California C-13 Fencing Contractor License: Scope, Verification, and Permit vs. License

The C-13 classification covers building and installing fences, gates, railings, guardrails, and backstops of wood, vinyl, chain-link, or metal — the enclosure trades.

It excludes masonry walls, which are C-29. It can overlap C-23 (ornamental iron railings and gates) and the D-28 doors-and-gates specialty (automatic and access-control gates) — so for an iron railing or a motorized gate, confirm the contractor's classifications match.

A contractor's license is the credential to do the work; a building permit is the city's approval for a specific project. They're different things, and conflating them is the most common fence confusion. Many California cities require a permit for fences above a height threshold — often six or seven feet — regardless of who builds it.

So a fence project can need both: an Active C-13 contractor and a city permit. Confirm who is pulling the permit (a licensed contractor pulls it in their own name) and that the height complies with local rules.

Any project where combined labor and materials total $1,000 or more must be performed by a CSLB-licensed contractor — the threshold rose from $500 to $1,000 on January 1, 2025 under Assembly Bill 2622 (Business & Professions Code §7048). Below $1,000, a narrow minor-work exemption can apply only if the job isn't part of a larger project and the worker discloses, in advertising and bids, that they aren't licensed.

A short run of fence under $1,000 in combined labor and materials can be unlicensed, with disclosure. A full perimeter fence is well over the threshold and should go to an Active C-13.

Confirm the license is Active and the C-13 classification is listed — on the CSLB "Check a License" tool or on the contractor's profile in this directory. Match the license to the business you're hiring. Check that the $25,000 contractor bond is on file (Business & Professions Code §7071.6) and that workers' compensation coverage — or a valid exemption — is shown.

Browse Active C-13 fencing contractors by city in the California fencing directory and see each one's dated CSLB status before you hire.

A fencing contractor must carry workers' compensation insurance for any employees. A contractor that genuinely works alone can currently file a no-employee exemption, so the CSLB record may show an exemption rather than a policy — confirm one or the other before you hire.

Senate Bill 1455 will extend that requirement to every CSLB licensee — regardless of employees — on January 1, 2028, with CSLB's exemption-verification process live by January 1, 2027. Five high-risk classifications already carry no exemption at all — C-8 (concrete), C-20 (HVAC), C-22 (asbestos abatement), C-39 (roofing), and D-49 (tree service) — and must hold coverage regardless of employees.
