CALIFORNIA CONSTRUCTION GUIDE  

OWNER-BUILDER EXEMPTION (B & P 7044) 

Who is considered to be an owner-builder? 

An owner-builder is any individual or group of individuals who own the property or building on which they plan to construct, alter, repair, improve, or remodel a building or structure. Also, a tenant may be considered an owner-builder (case-by-case). 

Is an owner-builder required to have a CSLB license? 

An owner-builder does not need to have a CSLB license, but there are limitations. 

A license is not required if: 

• The owner-builder does the work himself or herself or through his or her own employees, with wages as their sole compensation, and the structure(s) is/are not intended for sale; or 

• The owner-builder contracts with properly licensed subcontractors. This exemption applies to the construction of a single-family residential structure and limits the number of structures intended or offered for sale to four or fewer in a calendar year. 

The number of structures is unlimited if the owner-builder contracts with a General Building (B) contractor. 

Is a homeowner required to get a CSLB license if he/she wants to improve his/her home? 

A homeowner improving his or her principal place of residence does not need to have a CSLB license if all of the following exist: 

• The work is performed prior to sale; 

• The homeowner resides in the residence for the 12 months prior to completion of the work; and 

• The homeowner has not taken advantage of this exemption on more than two structures during any three-year period. 

Does the owner-builder exemption apply to an individual who builds homes for resale (speculation homes), and are there any limitations? 

Yes, the owner-builder exemption would apply to an individual who builds homes for resale under any of the following conditions: 

• Licensed tradesmen are hired to perform all work on the project (provided no more than four structures per calendar year are intended for resale); 

• A licensed general contractor is hired to perform and/or subcontract the completion of all work on the project (In this case, there is no restriction on the number of structures completed per calendar year.); or 

• The owner-builder performs the work, all or in part, and resides in the completed structure for one year prior to resale. (This applies to not more than two structures in a three-year period.) 

Are there any trades that property owners are prohibited from performing themselves? 

Yes, property owners are prohibited from performing well-drilling work covered under the Well Drilling (C-57) contractor classification. 

MINOR WORK EXEMPTION (B & P 7048) 

Is it true that a contractor’s license is not required if the work to be performed is under $500? 

Yes, B & P Section 7048 (Small Operations) provides an exemption from licensure for minor work if the aggregate contract price, including labor, materials, etc., is less than $500. This exemption does not apply if the “minor work” is part of a larger project. 

EXAMPLE: A homeowner is having a kitchen remodeled at a total cost of $6,000 and decides to sublet the flooring work, which is only $300. The person doing the flooring would not be exempt from licensure because the overall cost of the project was over $500. In addition, jobs cannot be broken down into hourly fees in order to sidestep the $500 threshold. 

CONTRACTOR LICENSE VERIFICATION 

Are local jurisdictions required by state law to verify a contractor’s license prior to the issuance of a permit? 

Yes. Any city or county that requires the issuance of a permit shall also require a written and signed statement from a licensed contractor stating that he or she is licensed, the number of the license, and that it is in full force and effect. Contractors are required by law to provide this information. (B & P 7031.5; Health and Safety Code 19825) 

Is there a similar requirement for unlicensed individuals who want to pull a permit? 

If the individual pulling the permit is exempt from licensure under Contractors License Law, then he or she must provide a written and signed statement giving the basis for the alleged exemption, and provide a workers’ compensation insurance declaration as required under Health and Safety Code 19825. 

MULTIPLE CLASSES FOR A PROJECT 

Is it possible that more than one classification could be appropriate for a single project? 

Yes. It is possible that similar contractor classifications might be utilized for a single project. 

EXAMPLE: Grading and paving a road can be performed by either a General Engineering (A) contractor or an Earthwork & Paving (C-12) contractor. 

GENERAL ENGINEERING (A) CONTRACTOR (B & P 7056) 

Can a General Engineering (A) contractor contract to perform the work of a single trade (specialty work) if that specialty work is an integral part of the scope of work for a General Engineering contractor? For example, a General Engineering contractor can build a freeway, which can include pouring concrete and putting up fences. Can they take a contract for concrete work only or to build a fence only? 

A General Engineering (A) contractor can contract to perform all or any part of a project that falls under the “A” classification. California Code of Regulations (CCR) Section 834(a) states: 

“...a general engineering contractor shall operate only within those areas defined in Section 7056 of the B & P Code.” 

Therefore a General Engineering (A) contractor could take a contract to build a fence or pour concrete if the work was originally or currently part of the type of projects listed in B & P Code Section 7056 (airports, roads and similar “fixed works”). 

GENERAL BUILDING (B) CONTRACTOR (B & P 7057) 

How is a General Building (B) contractor defined in Contractors License Law? 

B & P Section 7057(a) broadly defines General Building (B) contractor as “a contractor whose principal business is in connection with any structure built, being built, or to be built...requiring in its construction the use of at least two unrelated building trades or crafts...” . However, framing or carpentry projects may be performed without limitation. As further explained below in questions 13 and 14, a General Building contractor may contract for a project that involves a single trade, provided certain conditions are met. 

The last part of the first paragraph of Section 7057 states “... or to do or superintend the whole or any part thereof.” What does this mean? 

Any projects, or portions thereof, that are identified under Section 7057 as appropriate for the General Building (B) contractor classification may be completed by a “B” contractor through the licensee’s own forces, and/or by overseeing (superintending) the work of properly licensed subcontractors. 

Can a General Building (B) contractor take a “prime contract” for a single specialty trade? 

A General Building (B) contractor may take a prime contract for any specialty project (even if less than two trades) if they hold the specialty classification or subcontract the work to an appropriately licensed specialty contractor. 

Can a General Building (B) contractor take a “subcontract” for work involving a single trade if he plans to subcontract the work out? 

No, as provided in B & P Section 7057(b), a General Building (B) contractor cannot take any subcontract (a subcontract is when the “B” does not have a direct contractual relation with the owner of property) for any single trade project (excluding framing or carpentry), unless he/she holds the required specialty license classification.  For example, a “B” contractor may take a prime contract (contract directly with the owner of the property) to roof a home, and subsequently subcontract the work to a licensed roofing contractor. However, a “B” may not take a subcontract to roof a home, and subsequently subcontract the work out. 

How does the CSLB differentiate between a prime contract and a subcontract? 

A prime contract is a contractual relationship made directly between the owner of the property and the contractor. A subcontract is when the contractor does not have a direct contractual relationship with the owner of the property. In other words, the subcontractor contracts with the prime contractor.  

What prime contracts or subcontracts can a General Building (B) contractor take? 

A General Building (B) contractor can take a prime contract or subcontract for: 

a. Framing or carpentry projects; 

b. Projects that require at least two unrelated building trades other than framing or carpentry (This is known as the “two-or-more trades” rule: see note below.); or 

c. Any specialty projects (even if less than two unrelated trades) for which the “B” contractor also holds the required specialty class. 

NOTE: 

1. Framing or carpentry cannot be used to help satisfy the “two-or-more trades” rule. 

2. For a project that falls under a Specialty license classification, such as Plumbing 

(C-36) or Electrical (C-10), work that is “incidental and supplemental” to the completion of the project cannot be used to help satisfy the “two-or-more trades” rule. Incidental and supplemental work is defined by regulation, in relevant part: 

“…work in other [license] classifications is ‘incidental and supplemental’ to the work for which a specialty contractor is licensed if that work is essential to accomplish the work in which the contractor is classified…” 

Can a General Building (B) contractor take a contract for fire protection or well drilling work? 

Section 7057(c) prohibits a General Building (B) contractor from taking a contract for any project that includes work covered under a Fire Protection (C-16) or Well Drilling (C-57) classification, unless the General Building (B) contractor either holds the C-16 or C-57 class or subcontracts the work to a properly licensed specialty contractor. 

Can a General Building (B) contractor pull a roofing permit when the work involves replacing facia board, painting eaves and applying a new roof cover? 

A General Building (B) contractor can perform roofing (or re-roofing) work with his/her employees only if it is one portion of a project involving at least two unrelated trades, executed under either a prime contract or a subcontract. 

To fully comply with the provisions of B & P Section 7057, the contract in question would have to include the installation of roofing products and the work of at least one other specialty trade that is NOT an integral component of the roofing project. 

NOTE: 

The work involved in completing a re-roofing project frequently involves the installation of sheet metal as a flashing material, or some carpentry work to replace building components damaged as the result of moisture intrusion. This work is classified as being incidental and supplemental. As such, it is defined by Board Rule 831, and refers to work that is “essential” to completing the re-roof and is, therefore, not unrelated to the project and cannot be used in determining the “two or more unrelated trades” rule as it pertains to a “B” contractor. If you issue a building permit to a “B” contractor that you believe is violating the “two or more trades” rule, you should contact the CSLB so that the issue can be properly reviewed. 

The first paragraph of B & P Section 7057 refers to "chattels.” What are chattels? 

Chattels are moveable items of personal property, such as furniture, automobiles, or livestock. 

EXAMPLE: An equipment shed is a structure that is designed to house “chattels.” 

CONCRETE (C-8) CONTRACTOR (CCR 832.08) 

Can a Concrete (C-8) contractor contract and pull permits for a lattice patio cover? 

No, a Concrete (C-8) contractor can only work with wood when it is part of formwork for concrete. 

FIRE PROTECTION (C-16) CONTRACTOR (CCR 832.16) 

What is the proper license to install fire protection systems? 

B&P Section 7026.12 is very specific. It states: As defined in the California Code of Regulations Section 832.16 Fire Protection contractor, “The installation of a fire protection system, excluding an electrical alarm system, shall be performed only by a contractor holding a fire protection contractor classification...or by an owner-builder of an owner-occupied, single-family dwelling, if not more than two single-family dwellings on the same parcel are constructed within one year...”. 

LANDSCAPING (C-27) CONTRACTOR (CCR 832.27) 

Can a Landscaping (C-27) contractor pull permits and perform work involving gas lines and/or electrical circuits when yard lighting or a pre-manufactured spa or an outdoor barbecue is part of the landscaping contract? 

Yes, a Landscaping (C-27) contractor may pull permits and contract for such work, provided the work is part of or incidental to an overall landscaping project. 

NOTE: 

As a result of legislative changes to Business and Professions (B&P) Code Section 7027.5, a Landscaping (C-27) contractor may enter into a prime contract for the following improvements: 

• A swimming pool that is included within the landscaping project that the Landscaping (C-27) contractor is supervising provided that, if the landscaping contractor does not hold the Swimming Pool (C-53) classification, the construction of the swimming pool is subcontracted to a single contractor that does hold the Swimming Pool (C-53) contractor classification; 

• An outdoor residential cooking center that is included within the landscaping project that the Landscaping contractor is supervising. Any work that is outside of the field and scope of activities authorized to be performed under the Landscape (C-27) contractor classification may only be performed by a contractor holding the appropriate specialty license, or a General Building (B) contractor performing work in accordance with the requirements of subdivision (b) of Section 7057; or 

• An outdoor fireplace, provided that it is included within a residential landscape project that the contractor is supervising and is not attached to a dwelling. Any work that is outside of the field and scope of activities authorized to be performed under the Landscape (C-27) contractor classification may only be performed by a contractor holding the appropriate specialty license, or a General Building (B) contractor performing work in accordance with the requirements of subdivision (b) of Section 7057. 

Can a Landscaping (C-27) contractor contract and pull permits for patio covers or outdoor decks? 

A Landscaping (C-27) contractor may contract and pull permits for “non-watertight” patio covers or outdoor decks. 

If a patio cover is attached to the house, what classification(s) can build it? 

Patios with lattice-type covers can be built by a General Building (B) contractor, a Carpentry (C-5) contractor, or a Landscaping (C-27) contractor. 

Are there any restrictions on the size, height, or type of deck for which a Landscaping (C-27) contractor can contract or pull permits? 

Generally, there are no restrictions on the size, height, or type of deck. However, certain structural work may be precluded, which CSLB will review on a case-by-case basis. 

Can a Landscaping (C-27) contractor build a perimeter wall? 

Yes, but only if the perimeter wall is part of a total landscaping project. 

27. Can a Landscaping (C-27) contractor do a single trade, i.e. concrete, masonry, carpentry? 

Yes, a Landscaping (C-27) contractor may undertake any single trade contract, provided such work is a part of: 

“...landscape systems and facilities...which are designed to aesthetically, architecturally, horticulturally, or functionally improve the grounds within or surrounding a structure or a tract or plot of land...” (CCR 832.27). This includes items such as lattice-type patio covers, and masonry block walls that are decorative in nature. 

If an outdoor wall is built simply for its aesthetic value, what classification is required? 

A Landscaping (C-27) contractor or Carpentry (C-5) contractor would be appropriate if carpentry skills are required. A masonry wall would require either a Landscaping or Masonry (C-29) contractor. A General Building (B) contractor may perform this work if it is part of a larger construction project that falls within the scope of work the General Building (B) contractor classification as defined in B & P Section 7057. 

PLUMBING (C-36) CONTRACTOR (CCR 832.36) 

Can a Plumbing (C-36) contractor contract and pull permits for the installation of a seepage pit or other components of a septic system? 

A Plumbing (C-36) contractor may contract and pull permits for installation of a seepage pit or other components of a septic system. A General Engineering (A) contractor or Sanitation System (C-42) contractor may also perform this work. All three licenses are appropriate to install or repair all septic systems.  

What license classifications are allowed to install or repair building sewers? 

General Engineering (A) contractors, Plumbing (C-36) contractors, Sanitation System (C-42) contractors, and Pipeline (C-34) contractors may install and/or repair building sewers. A General Building (B) contractor may perform this work if it is part of a larger construction project that falls within the "B" contractor classification scope of work as defined in B & P Section 7057. 

What license or certification is appropriate to remove underground storage tanks? 

Underground storage tank removal requires the Hazardous Substance Certification in addition to the appropriate license classification. 

A General Engineering (A) contractor is appropriate to install and/or remove underground storage tanks for any purpose whatsoever at any location. 

A Plumbing (C-36) contractor is appropriate to install and/or remove any underground storage tank that provides a service to a building. This includes storage tanks for service stations. 

A Limited Specialty Service Station Equipment (C-61/D-40) contractor is appropriate to install and/or remove underground fuel storage tanks with a capacity of up to 20,000 gallons at service stations or any other site. 

A General Building (B) contractor is appropriate to install and/or remove an underground storage tank only if such work is performed within the meaning of B & P Section 7057, the definition of a General Building contractor. 

ROFING (C-39) CONTRACTOR (CCR 832.39) 

Can a Roofing (C-39) contractor pull a repitch/reroof permit, including the framing and structural work that is involved? 

Generally, structural changes are inappropriate for the C-39 contractor on a reroof/repitch. However, certain projects may require special consideration. CSLB will make a determination on a case-by-case basis. 

SWIMMING POOL (C-53) CONTRACTOR (CCR 832.53) 

Can a Swimming Pool (C-53) contractor contract and pull permits for a patio cover? 

No, a Swimming Pool (C-53) contractor cannot contract or pull permits for a patio cover. 

SIGN INSTALLATION 

What classification of license is appropriate for the installation of signs? 

If the installation of a sign falls under the definition of contracting (B &P 7026), the following licenses would be appropriate: 

Electrical Signs 

• Electrical (C-10) contractor 

• Electrical Sign (C-45) contractor 

Non-Electrical Signs 

• Electrical Sign (C-45) contractor 

• Sign Installation (C- 61/D-42 Limited Specialty) contractor 

NOTE: 

Installation of any sign that falls under the purview of the Outdoor Advertising Act [California Administrative Code, Title 4, Chapter 6] does not require a contractor’s license. Billboards are the most common. These types of installations require registration with the California Department of Transportation. 

ALARM COMPANY OPERATOR (B & P 7054) 

Is an alarm company operator required to be licensed by the Bureau of Security and Investigative Services (BSIS) and the Contractors State License Board? 

Burglar Alarm Systems 

• Under Contractors License Law (B & P Section 7054), individuals who install, maintain, monitor, sell, alter, or service burglar alarm systems do not have to be licensed by CSLB if they are licensed by BSIS. 

Fire Alarm Systems 

• Fire alarm work is subject to Contractors License Law and requires an Electrical (C-10) contractor license. 

STRUCTURAL PEST CONTROL OPERATOR 

Is a structural pest control operator who is licensed by the Structural Pest Control Board required to have a contractor’s license when making structural repairs caused by wood-destroying pests or organisms? 

Business and Professions Code Section 7051 of the Contractors License Law states, in relevant part: “This chapter does not apply...to a licensed structural pest control operator acting within the scope of his or her license...”. This section of the license law provides a conditional exception to the contractor licensing requirement for licensed pest control operators. The operator can perform relevant repairs to the deteriorated portions of the structure, but only to the extent that is necessary in order to correct a condition for which a license has been granted by the Pest Control Board. If you believe that a pest control operator has performed construction work in violation of this condition, thoroughly document the situation and contact the CSLB. 

(Structural Pest Control Act, Chapter 14, Article 1 Section 7505 and Article 4 Section 8560). The key is replacement of damaged members. 

AGRICULTURE EXEMPTION (B & P 7049) 

What is an agriculture exemption? 

B & P Section 7049 provides an exemption from licensure for any “construction or operation incidental to the construction and repair of ... farming, dairying, agriculture, viticulture, horticulture...”. However, if a licensed contractor performs work included in the agriculture exemption, CSLB has jurisdiction over complaints (B & P 7049). 

ADVERTISING 

Are licensed contractors required to include their license numbers in advertisements? 

Yes. Any time licensed contractors advertise their services, whether on paper, over the air waves or on the Internet, a license number must appear. This includes but is not limited to letterhead, business cards, and any type of directory listing, airwave transmissions, newspaper ads, vehicle lettering, or any form of advertising (B & P 7030.5). 

Is it against the law for an unlicensed individual to advertise construction services? 

No, provided the advertisement includes a statement that the individual does not hold a contractor’s license (B & P 7027.2). An advertisement by an unlicensed individual must include a statement, such as “not state licensed.” 

NOTE: Even if the ad correctly states that the individual is unlicensed, he/she can only perform contracting services that total less than $500 in labor and materials.  Larger projects cannot be broken down into pieces, not charged by the hour in order to sidestep the $500 threshold. 

WORKERS’ COMPENSATION INSURANCE VERIFICATION 

Are local jurisdictions required by state law to verify workers’ compensation insurance prior to issuing a permit? 

Under Labor Code Section 3800(a), city and county building departments “...shall require that each applicant for the permit sign a declaration under penalty of perjury verifying workers’ compensation coverage or exemption from coverage as required by Health and Safety Code Section 19825. 

Does CSLB maintain a record of workers’ compensation coverage for licensed contractors? 

Yes. CSLB is required to maintain a record of workers’ compensation coverage or exemption. This information is available on the CSLB Web site, www.cslb.ca.gov or by calling the toll-free automated assistance number, 800.321.CSLB (2752). 

NOTE: 

All Roofing (C-39) contractors are required to carry a workers’ compensation insurance policy, regardless of whether they have employees. 

AMOUNT OF DOWN PAYMENT 

Is the amount of a down payment fixed by law? 

Yes. Contractors License Law states that a down payment for any home improvement contract may not exceed $1,000 or 10 percent of the contract price (excluding finance charges), whichever is less. A contractor is exempt from this restriction when s/he furnishes a performance and payment bond, lien and completion bond, or a bond equivalent or joint control that is approved by the Registrar of Contractors and that covers full performance and payment. 

CONTRACTOR FIRED, NEW ONE HIRED 

Does CSLB get involved when a consumer fires one contractor and hires another? 

If there are no violations of the Contractors License Law, CSLB has no jurisdiction over the firing or hiring of a contractor. 

CONTRACTOR STAMPS & SIGNING PLAN CHECK DOCUMENTS 

What laws are involved when a licensed contractor signs and submits drawings for a building department’s plan check? 

Licensing laws for design professionals (architects, engineers) require a stamp and signature on construction drawings as evidence of responsibility. This is usually done in a specific location on the drawings. 

Licensed contractors do not have a similar stamp and/or signature requirement. However, under the Architects Practice Act (Act), anyone who prepares plans for others, including those who are not licensed architects, is required to sign their documents. Since the Act allows licensed contractors to prepare plans for work they will install themselves, such as designing/building mechanical and electrical systems, they are required to sign the construction documents they create for building department approval. (B & P Code Section 5536.1)  

Can licensed contractors use a stamp on a drawing submitted to a building department? 

A stamp can be used by a licensed contractor only if it provides truthful and factual information about their CSLB license and/or qualifications of a person or business submitting the drawing. It should not be confusingly similar in appearance to those required by licensed or registered design professionals (architects, engineers).  

A licensed contractor can use a stamp to provide additional clarifying information when complying with the signature requirements of the Architects Practice Act. However, the licensed contractor may be violating the law if a stamp is used or placed in a manner that might misrepresent or lead one to believe that the person is qualified to prepare construction drawings beyond that which is authorized by law. (B & P Code Section 5536.1) 

What constitutes a misrepresentation of a licensed contractor’s stamp? 

Misrepresentation can occur when a licensed contractor places a stamp in a signature block designed for an architect or engineer. It can also occur when a licensed contractor stamps drawings for non-exempt project types or for work other than that which the licensed contractor is authorized to design and build. 

What are the requirements for an architect’s stamp? 

The law (Business and Professions Code Section 5536.1) specifies that the 

architect’s stamp must contain five different items: 

• The words: “State of California” 

• The term: “Licensed Architect” 

• The architect’s name 

• The architect’s license number 

• Renewal date of the license 

The stamp must be a circular shape that is 1- to 2-inches in diameter. The design of the circle may include solid lines (thin or thick) or broken lines, such as dashes or dots. Other possibilities include a rope or beaded effect or words forming the circle. “Ren.” refers to the renewal date. 

Embellishments (stars, graphic designs) are also acceptable as long as the stamp is legible. The stamp shall not be of the embossing type. The previous page shows basic examples of recommended formats for a California architect’s stamp. For more information, visit the California Architects Board Web site: www.cab.ca.gov. 

GENERAL COMPLAINT INFORMATION 

How can a homeowner find information on how to file a complaint with CSLB? 

The easiest way to locate information is to log onto CSLB’s Web site, www.cslb.ca.gov. Consumers can also call CSLB’s toll-free automated assistance number, 800.321.CSLB (2752). 

Will the Board investigate if a complainant wishes to remain anonymous? 

There is a “confidential” box on the complaint form for individuals who wish to remain anonymous. However, this limits the type of complaints investigated since CSLB cannot mediate a workmanship complaint with a licensed contractor unless the contractor is informed of the details of the job (site, homeowner, complainant issues). 

How long does a person have to file a complaint? 

CSLB has jurisdiction over licensed contractors for up to four years from the date of an illegal act for patent defects and up to 10 years for latent “structural” defects. Jurisdiction for unlicensed contractors is up to four years from the date of the illegal act. [B & P 7091(a)(b) & B & P 7028(d)] 

How does CSLB define “structural defect?” 

Based on the California Code of Regulations (CCR), the three elements below are required for a defect to be considered a “structural” defect as referenced in B&P 7091: 

• There is a failure or probable failure in the load-bearing portions of a structure; 

• The failed portions were not constructed in compliance with the Code (this requires a violation notice from the building official); and 

• The failure or condition results in the inability to use the affected portion of the structure for the purpose for which it was intended. 

What if there is a warranty extending past four or ten years? 

If a complaint is filed with the CSLB alleging that a contractor has violated the terms of a warranty, the CSLB must file a legal action to discipline the licensee the date that the complaint was filed, whichever is later, within 18 months after the warranty expires. 

What kinds of complaints can be forwarded to CSLB for investigation? 

Complaints within CSLB’s jurisdiction involve failure of a licensed contractor to fulfill the terms of an agreement, including poor workmanship; the requirement of a down payment in excess of the amount allowed by law; job abandonment; failure to pay subcontractors or material suppliers; building code violations; use of false, misleading or deceptive advertising; violations of the Home Improvement Act; and violations of the Swimming Pool Act. 

Does CSLB investigate fraud reported by consumers? 

Yes. Fraud is a cause for disciplinary action. (B & P 7116) 

What is the minimum documentation required by CSLB to pursue a complaint against a licensed contractor for performing construction work? 

There is no minimum documentation required to pursue a complaint. However, the contractor must be identifiable and there must be an alleged violation of the Contractors License Law. All complaints are reviewed to determine whether they are within the CSLB’s jurisdiction. 

HOW BUILDING OFFICIALS REFER CASES TO CSLB 

Does CSLB accept referrals from building officials? 

Yes, there are procedures in place for building officials to refer cases and for CSLB to address those referrals. 

Is there a special form to be used by building officials? 

Yes, a special referral form for building departments to use can be found in the “Building Officials” section on the CSLB Web site, www.cslb.ca.gov.  

What other documents should building officials include? 

Filing the following documents with the complaint form may help shorten the time of an investigation: 

• Certified copies of permits and applications for permits; 

• Certified copies of correction notices; and 

• Certified copies of letters of citation to respondent. 

Do building officials have to appear as a witness? 

Very rarely will a building official need to testify during the hearing process. 

What happens to the complaint when it reaches CSLB? 

CSLB Intake and Mediation Center supervisors have been instructed to review complaints from building officials upon receipt and assign the appropriate priority based on the seriousness of the complaint. As with all complaints, those involving serious health and safety matters are given highest priority. 

Who should I contact if I have questions about a complaint? 

Contact the CSLB office nearest you for general complaint information.  

DESCRIPTION OF CSLB LICENSE CLASSIFICATIONS 

The California Contractors State License Board issues licenses to contract in particular trades or fields of the construction profession. Each separate trade is recognized as a “classification.” Licensed contractors may add any classification for which they are qualified. Classification statutes are cited from California Business and Professions Code Sections 7008 and 7056-7059. 

CSLB ISSUES LICENSES FOR THE FOLLOWING CLASSIFICATIONS: 

Class “A” — General Engineering Contractor 

The principal business is in connection with fixed works requiring specialized engineering knowledge and skill. 

Class “B” — General Building Contractor 

The principal business is in connection with any structure built, being built, or to be built, requiring in its construction the use of at least two unrelated building trades or crafts. 

Class “C” — Specialty Contractor 

There are 41 separate “C” license classifications for contractors whose construction work requires special skill and whose principal contracting business involves the use of specialized building trades or crafts. 

GENERAL CONTRACTORS 

General Engineering (A) Contractor 

A General Engineering contractor is a contractor whose principal contracting business is in connection with fixed works requiring specialized engineering knowledge and skill, including the following divisions or subjects: irrigation, drainage, water power, water supply, flood control, inland waterways, harbors, docks and wharves, shipyards and ports, dams and hydroelectric projects, levees, river control and reclamation works, railroads, highways, streets and roads, tunnels, airports and airways, sewers and sewage disposal plants and systems, waste reduction plants, bridges, overpasses, underpasses, and other similar works, pipelines and other systems for the transmission of petroleum and other liquids or gaseous substances, parks, playgrounds and other recreational works, refineries, chemical plants and similar industrial plants requiring specialized engineering knowledge and skill, powerhouses, power plants and other utilities plants and installations, mines and metallurgical plants, land leveling and earthmoving projects, excavating, grading, trenching, paving and surfacing work and cement and concrete works in connection with the above mentioned fixed works. (Business and Professions Code Section 7056) 

General Building (B) Contractor 

(a) A General Building contractor’s principal contracting business is in whole or partial connection with any structure built, being built, or to be built, for the support, shelter and enclosure of persons, animals, chattels, or moveable property of any kind requiring in its construction the use of at least two unrelated building trades or crafts, or to superintend the whole or any part thereof. This does not include anyone who merely furnishes materials or supplies under Section 7045 without fabricating them into, or consuming them in the performance of the work of the general building contractor. (b) A General Building contractor may take a prime contract or a subcontract for a framing or carpentry project. However, a general building contractor shall not take a prime contract for any project involving trades other than framing or carpentry unless the prime contract requires at least two unrelated building trades or crafts other than framing or carpentry, or unless the general building contractor holds the appropriate license classification or subcontracts with an appropriately licensed contractor to perform the work.
