Town of Fairfax

Fairfax states it implements the California Building, Electrical, Plumbing, and Mechanical Codes, and its permit application requires a construction permit before work subject to those codes. The application is used for building, electrical, plumbing, mechanical, and demolition permits.

• Exempt Fairfax's public-facing materials reviewed do not post a Fairfax-specific exempt-work list
• Exempt Because Fairfax applies the California Building, Electrical, Plumbing, and Mechanical Codes, permit exemptions generally follow the applicable California code exemptions administered by the local enforcing agency
• Exempt California mechanical-code administration materials referenced by the State note that work exempt from permits and minor changes or repairs not affecting structural features, egress, sanitation, safety, or accessibility may be exempt, as determined by the enforcing agency

Note: Exemptions do not authorize work that violates any other law or code requirement. Fairfax applicants should confirm claimed exemptions with the Building Official before starting work.

Building code

Fairfax reported that the Town Council updated its building and fire codes on November 5, 2025, after previously adopting code updates in 2022. The Planning and Building page states the Town implements the California Building, Electrical, Plumbing, and Mechanical Codes.

Permit validity

Fairfax's application and inspection card state the permit expires 180 days from issuance. One written extension of up to 180 additional days may be requested from the Building Official before expiration.

Owner-builder

Fairfax uses a formal owner-builder declaration in the permit application and separately posts an owner-builder advisory. The Town warns that owner-builders may assume responsibility for construction management, worker injuries, payroll/tax compliance, and liability if unlicensed workers are used.

Contractor requirements

The permit application requires either a California licensed contractor declaration or an owner-builder declaration citing Business and Professions Code Sections 7031.5 and 7044. Owners contracting the work must use licensed contractors to rely on that exemption path.
