Step One, Look Up the License
Ask for the license number. Type it into the CSLB license lookup. Check that the name matches the person or company you are talking to. Check that the status is current and active.
Do this even when someone you trust sent the contractor, including us. It takes a minute.
Step Two, Check the Class
The CSLB says a C-8 is the CSLB license class for concrete work. It covers forming, pouring, placing and finishing flat and mass concrete. concrete contractor forms, pours, places and finishes mass, pavement and flat concrete. That fits driveways, patios, walks, slabs and concrete walls.
A B general contractor can also run a concrete job. The B may hold C-8 or may hire a licensed C-8 for the concrete. Read general contractors and concrete before you sign, and ask for the name and license of any sub.
For work in the street, ask the city which license it wants. The CSLB guide says an A general engineering contractor may do concrete work that is part of roads and similar fixed works.
Step Three, Know the $1,000 Rule
Since January 1, 2025, AB 2622 set the minor work limit at $1,000. Below that, an unlicensed person may take the job only if it needs no permit and they hire no help. An unlicensed person who advertises must say they are not licensed.
Anyone who claims to be licensed or qualified as a contractor cannot use this exemption. Over $1,000 in labor and materials, hire a licensed contractor.
Step Four, Get It in Writing
A written contract should name the contractor and license number, the exact work, the slab thickness and base, the finish, the start and end dates, the price and the payment schedule. It should say who gets permits and who calls 811.
Never pay in cash with no receipt. Never let work start on a handshake.
Step Five, Call 811
Whoever digs must call 811 at least two working days before digging, per Government Code 4216.2. Ask your contractor to show you the ticket.
