How to Get Your Masonry (C-29) Contractor License in California

How to Get Your Masonry (C-29) Contractor License is the CSLB classification for contractors whose work includes installs concrete units, baked clay products, concrete, glass and clay block, natural and manufactured stone, terra cotta, refractory materials and related masonry work. If your projects center on CMU walls, structural and non-load-bearing masonry; retaining walls, flatwork and staircases; precast masonry, glass block and decorative masonry; masonry veneer, fireplaces, chimneys and outdoor cooking areas, this is the license to investigate. The application requires a qualifying individual, documented experience, the Law and Business examination, and the Masonry (C-29) trade examination. This guide lays out the scope, application sequence, study priorities, and the records to assemble before filing.

Do you need the C-29 license?

CSLB describes this classification as work involving installs concrete units, baked clay products, concrete, glass and clay block, natural and manufactured stone, terra cotta, refractory materials and related masonry work. In practical terms, the license fits a contractor who regularly performs CMU walls, structural and non-load-bearing masonry; retaining walls, flatwork and staircases; precast masonry, glass block and decorative masonry; masonry veneer, fireplaces, chimneys and outdoor cooking areas. The boundary matters when a project combines trades: a C-29 license does not automatically authorize ceramic tile installation, which is generally C-54; standalone structural steel erection; unrelated plumbing, electrical or general building work.

Use the classification description as a scope check before you sign a contract. If the job includes a separate trade, plan a properly licensed subcontractor or confirm whether another classification is required. The license code is a business authorization, not a blanket permission to perform every task on a construction site.

Experience and application requirements

The qualifying individual must document at least four years of experience at a journeyman level or higher in the classification. CSLB lists journeyman, foreman, supervising employee, contractor, and qualifying owner-builder experience as possible categories; a responsible person with firsthand knowledge must verify the claim. There is no general education requirement, although CSLB may grant up to three years of credit for qualifying education or training, with at least one year of practical experience (CSLB qualifying experience).

Before filing, build a folder with the business information, the qualifying individual's work history, the Certification of Work Experience, and any training records. Describe the actual masonry tasks performed, not only the employer's job title. Specific dates, project types, and duties make the certification easier for the verifier to review.

The application process, step by step

1. Choose the business structure and qualifier. Decide whether the applicant will be a sole owner, corporation, LLC, or another eligible entity, then identify the person who will satisfy the experience and examination requirements.
2. Document the four years. Ask a qualified certifier who observed the work to complete the certification. Keep payroll, project, apprenticeship, or other supporting records available if CSLB asks for them.
3. Submit the original application. The current CSLB fee table lists $450 for one classification. Use the current form and follow CSLB's mailing or online instructions.
4. Wait for CSLB's review and examination notice. Processing time varies. Do not schedule the PSI examinations until CSLB refers you and the notice tells you how to pay and schedule.
5. Schedule both examinations with PSI. Each examination is separate. PSI states that candidates receive 3-1/2 hours for each examination and may retake a failed exam after 21 calendar days (CSLB examination FAQ).
6. Complete the issuance file. After passing, submit the required bond, workers compensation documentation or eligible exemption, and the initial license fee. CSLB's issuance instructions control the final documents (CSLB issuing a license).

What the C-29 exams cover

The trade examination is closed-book, computer-based, and multiple choice with four choices per question. The official CSLB guide says questions are written to have one best answer, a calculator is provided when needed, and there is no penalty for guessing. The current content outline is:

Study from the official guide for the version that matches your exam date. The weights are approximate, so do not ignore a smaller section; instead, use the table to decide where your first review hours should go. The Law and Business examination is separate and covers contracts, business management, employment, safety, insurance, and related rules (CSLB Law and Business guide).

A practical preparation path

Start with the official CSLB examination study guides to learn the vocabulary and topic outline. Then use Peerless Masonry (C-29) Study Guide Book, CSLB Masonry (C-29) practice examination, and the online practice exam to turn each topic into retrieval practice. A useful weekly loop is: read one topic, write a short job-site explanation in your own words, answer a focused set of questions, and record why each missed answer was wrong. Increase mixed practice only after the topic-level errors are shrinking.

Aim to score at least 85% consistently on fresh practice sets before scheduling or sitting for the exam. That is a preparation target, not a CSLB-published passing score. The goal is to show that you can recognize the best answer under time pressure, not that you memorized one question set.

After you pass

Passing the exams does not by itself activate the license. Review the bond and insurance requirements, answer CSLB's issuance request, and pay the correct initial license fee for the business structure. The standard contractor bond is $25,000, but the amount of a bond is not the same as the premium you pay to a surety; an RME or certain corporate qualifiers can require a separate $25,000 bond (CSLB bond requirements).

FAQ

Can I use experience from another trade for the C-29 license?

Only experience that supports the classification should be claimed for this application. Related work may help if it actually demonstrates masonry duties, but a job title alone does not establish qualifying experience. Use the CSLB form and ask a person with firsthand knowledge to verify the work in detail.

Does the C-29 trade exam have a public fixed passing percentage?

CSLB tells candidates the percentage required at the test site, but it does not publish one universal public passing percentage for every trade exam. Treat 85% on practice sets as a readiness target, then follow the instructions in your CSLB and PSI notices.

Do I need a school to qualify for this license?

No. CSLB does not require a general school credential to qualify. You need the required experience or approved credit, a valid application, and passing examinations unless a waiver applies. A school, book, or practice program is a preparation choice, not a substitute for the CSLB application requirements.

What if my project crosses into another classification?

Pause before signing and map each scope item to a license classification. For example, ceramic tile installation, which is generally C-54; standalone structural steel erection; unrelated plumbing, electrical or general building work. Use a properly licensed subcontractor or obtain the classification that covers the additional work. When the boundary is uncertain, check CSLB's classification descriptions or obtain professional advice before advertising or contracting.

How should I prepare if I am working full time?

Use short, repeatable sessions rather than saving all study for one weekend. Review the official outline, focus on the largest weighted sections, complete mixed practice under timed conditions, and keep an error log. The California contractor license roadmap can help place exam preparation inside the larger application sequence.
