Common Questions

C-47 General Manufactured Housing license FAQ

The C-47 (General Manufactured Housing) installs, moves, and services factory-built manufactured and mobile homes, including their foundations and utility connections. The B (General Building) license is for site-built structures. If your work is setting and servicing manufactured homes, you need the C-47; if you build homes on site from the frame up, you need the B.

Yes, on single-family placements. The C-47 scope allows connecting gas, water, sewer, and electrical utilities at a single-family manufactured-home placement. Broader multi-family utility work, or standalone plumbing and electrical jobs, may require a C-36 or C-10.

No. The C-47 covers manufactured homes, mobilehomes, and multifamily manufactured homes. It specifically excludes recreational vehicles, commercial coaches, and factory-built housing. The classification is also co-regulated with the California Department of Housing and Community Development (HCD).

Most students are exam-ready in 4–6 weeks of CSLS prep. Adding CSLB application processing (typically 2–4 weeks), exam scheduling, and posting your $25,000 bond, the full path usually runs 2–4 months from start to license-in-hand.

4 full-time-equivalent years of journey-level manufactured housing installation experience within the past 10 years; CSLB prorates part-time work. Qualifying work may be as a journeyperson, foreperson, supervising employee, contractor, or owner-builder. This can include work as a journeyman, foreman, or supervising employee. Up to three years can be satisfied with approved technical training, apprenticeship, or education.

The C-47 trade exam covers manufactured-home installation standards, foundation systems, tie-downs, utility connections, and HCD regulations. You need the current version-specific CSLB passing score to pass. With CSLS exam prep, 99% of students pass on their first attempt, backed by our 100% Money-Back Guarantee.

Plan on roughly $885 in mandatory costs before exam prep: the $450 application fee, the $200 initial license issuance fee, about $150 for the first-year premium on your $25,000 bond, and around $85 for fingerprinting. Exam prep is separate.
