California C-29 Masonry Contractor License: Scope, Verification, and Unlicensed-Work Limits

The C-29 license is the California classification for masonry contractors — block, brick, stone, and concrete-masonry-unit walls, masonry fences, pavers, and masonry waterproofing. Any masonry job of $1,000 or more in combined labor and materials must be done by a licensed contractor; below that, a person can do minor work only if it isn't part of a larger project and they disclose they're unlicensed.

Summary — key takeaways

  • C-29 is the CSLB classification for masonry contractors.
  • It covers block, brick, stone, and CMU walls, masonry fences, pavers, and masonry waterproofing.
  • Masonry overlaps C-8 (concrete), C-27 (landscape pavers), and C-13 (fences without masonry).
  • Masonry work of $1,000+ (labor + materials) requires a licensed contractor (AB 2622, 2025).
  • An unlicensed mason may legally take only sub-$1,000 minor jobs, with disclosure.

What a C-29 masonry license permits

The C-29 classification covers masonry: concrete units (CMU/block), brick, stone, terra cotta, and similar units laid in mortar — structural and non-structural walls, masonry fences and planters, pavers set in or on a masonry base, and masonry waterproofing.

It overlaps neighboring trades: poured concrete flatwork is C-8, landscape pavers can fall under C-27, and a fence with no masonry is C-13. For a job that mixes, say, a poured footing and a block wall, confirm the contractor's classifications cover the actual work.

How masonry overlaps concrete, pavers, and fencing

Block and brick walls, stone veneer, and mortar-set pavers are C-29 work. Poured concrete driveways, patios, and slabs are C-8 concrete. Pavers installed as part of a landscape can be C-27. A fence built without masonry — wood, vinyl, chain-link, or iron — is C-13, not C-29.

These overlaps are why 'who do I hire' is confusing for hardscape. The safe move is to read the contractor's CSLB classifications and match them to your specific job.

What masonry work legally requires a licensed contractor

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.

An unlicensed person may legally perform only minor masonry work under $1,000 in combined labor and materials, and only if it isn't part of a larger project and they disclose they aren't licensed. Contracting at or above $1,000 without a license is a misdemeanor (Business & Professions Code §7028) — so an unlicensed mason quoting a $4,000 patio wall is the red flag, not the bargain.

How to verify a C-29 masonry contractor

Confirm the license is Active and the C-29 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-29 masonry contractors by city in the California masonry directory and see each one's dated CSLB status before you hire.

The masonry workers' compensation rule

A masonry 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.

Frequently asked questions

Do I need a licensed masonry contractor for a small job in California?

Only masonry work under $1,000 in combined labor and materials can be done unlicensed, and only with disclosure and if it isn't part of a larger project. At or above $1,000, hire an Active C-29 contractor.

How much can an unlicensed mason charge in California?

An unlicensed person may legally take only minor jobs under $1,000 in combined labor and materials. Contracting at or above that threshold without a license is a misdemeanor under Business & Professions Code §7028.

Does a general (B) contractor cover masonry work?

A B can perform masonry as part of a larger multi-trade project, but for a standalone masonry job it needs the C-29 classification or must subcontract the work to a licensed C-29 mason.

What license does a paver or block-wall contractor need in California?

Masonry block and brick walls and mortar-set pavers are C-29 work. Landscape pavers can fall under C-27, and poured concrete is C-8 — match the contractor's classifications to your job.
