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

The C-29 classification covers masonry: concrete units (CMU/block), brick, stone, terra cotta, and similar units laid in mortar, in 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.

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.

Any project where labor, materials, and all other items 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 is casual, minor, and standalone (not part of a larger project), requires no building permit of any kind, no one is employed on the job, and any advertising discloses that the person is not licensed.

An unlicensed person may legally perform only minor masonry work under $1,000 in labor, materials, and all other items, and only if it isn't part of a larger project, no one is employed on the job, 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.

Confirm the license is Active and the C-29 classification is listed, either 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.

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. Since January 1, 2026 (SB 291), a licensee caught employing workers without coverage faces minimum penalties of $10,000 per violation for a sole owner and $20,000 per violation for a partnership, corporation, or LLC, and cannot renew without current coverage.

Senate Bill 1455 will extend that requirement to every CSLB licensee, regardless of employees, on January 1, 2028, with CSLB's exemption-verification process due 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 C-61/D-49 (tree service), and must hold coverage regardless of employees.
