Direct Answer: SB 342 takes effect January 1, 2027. It softens license lapse penalties on public works, commercial, and institutional jobs. Private residential property of 25 units or fewer was carved out, so homeowners keep the old rule.
Most people call me about a patio or a fireplace, not about contractor law. But a homeowner in Moss Landing recently finished a detailed repair request to me with one line that stuck: please confirm your license and insurance information. That is the right instinct, and a law taking effect soon makes it matter even more.
Senate Bill 342 was signed by Governor Newsom on September 30, 2026, and it becomes effective January 1, 2027. It changes what happens when a contractor’s license lapses in the middle of a job.
The short version for anyone here in Monterey County: if you own a house in Carmel Valley or Pacific Grove, your protection does not change. If you manage a commercial building in Monterey, some of your leverage in a payment dispute goes away in January.
What SB 342 and the California contractor license lapse change actually do in 2027
California’s Business and Professions Code section 7031 has always been blunt. If a contractor performed work while unlicensed, that contractor generally cannot sue to get paid, and the owner can generally recover everything already paid out, even for work that was done well.
That applied even when the lapse was short and accidental. A missed renewal date or a bond gap for a few weeks could wipe out payment on an entire project.
SB 342 amends section 7031 and limits that outcome on larger project types. Starting January 1, 2027, on the covered categories below, a contractor whose license lapses mid project can still be paid for the work performed while licensed, and the owner can generally only claw back payments tied to the unlicensed period.
The categories the new law reaches include:
- Public works projects
- Commercial projects
- Institutional projects
- Multifamily and common-interest-development construction
The law was announced in the Governor’s legislative update on September 30, 2026. For contractors, this is relief from an all or nothing penalty. For the people paying the bills on those projects, it is a reduction in leverage.
Homeowners were carved out, and that is good news for you
Private residential work on property of 25 units or fewer was excluded from the new rule. The old all or nothing consequence still applies there.
So if you are having a stone patio built in Pebble Beach, a fireplace facing redone in Carmel, or a block retaining wall rebuilt in Salinas, nothing about your remedy changes on January 1.
If your mason works while unlicensed, section 7031 still gives you the strong position it always has. That is worth understanding before you sign anything, because the remedy only helps if the problem is a licensing lapse rather than sloppy work.
A few things this protection does not do:
- It does not fix a failed wall or a cracked patio on its own
- It does not put your project back on schedule
- It does not cover you for injuries if the contractor carries no workers compensation
- It does not substitute for checking the license before the first stone is set
I have walked onto jobs where someone else’s retaining wall was built with no drainage and no proper footing depth. A legal remedy after the fact is a poor trade for a wall that holds. If you are already seeing movement, these are the signs a wall needs a masonry contractor rather than a patch.
Who the January 1, 2027 change covers
Here is the split in plain terms. Project type decides which rule applies to a mid project license lapse.
| Project type | Rule starting January 1, 2027 | What it means for the owner |
|---|---|---|
| Single family home, Monterey Peninsula | Old rule stays in place | Strong existing remedy under section 7031 is unchanged |
| Private residential property, 25 units or fewer | Carved out of SB 342 | Same protection as before the law |
| Commercial or institutional building | Covered by SB 342 | Clawback generally limited to the unlicensed period |
| Public works project | Covered by SB 342 | Contractor can be paid for work performed while licensed |
| Multifamily and common-interest developments | Covered by SB 342 | Less payment leverage in a license dispute |
What Peninsula commercial owners and property managers should change in January
If you manage commercial property around Monterey, this is the part that affects your contracts. After January 1, discovering a lapse halfway through the job will not hand you the whole payment back.
That pushes the work to the front end. Verification at contract signing and during the job becomes the real protection, not a dispute afterward.
For masonry work specifically, I would build these into your process:
- Record the C-29 or B license number in the contract itself, not just on a proposal
- Note the license expiration date and set a reminder before it hits on long jobs
- Request current certificates for the bond and general liability, plus workers compensation
- Re-check the license status at any major draw or milestone payment
- Keep a dated screenshot of each check in the project file
This matters more on older buildings here. Monterey’s unreinforced masonry hazard-reduction requirements mean some facade and wall work is tied to a compliance deadline, not just a maintenance budget.
A stalled job on a URM building is expensive in a way a stalled patio is not. If you are weighing scope on an aging structure, this breakdown of when a commercial block wall needs more than a patch covers what usually drives that call.
When to check a mason’s license on a job
Four checkpoints that work for both homeowners and commercial owners, and take about five minutes each.
How I would verify a license in five minutes
The Contractors State License Board runs a free check-a-license tool on its website. You type in a name or license number and it shows status, classification, bond, and workers compensation.
For masonry, the classification you want is C-29. A general B license can also cover masonry inside a larger project, but a C-29 is the specific masonry designation.
What I look at, in order:
- Status reads active, with no suspension
- Classification matches the work being quoted
- Bond is on file and current
- Workers compensation is reported, not exempt, if a crew is coming
- The business name on the contract matches the name on the license
If anything looks off, ask before you pay a deposit. A legitimate contractor will not mind. Our license is CSLB #1073620, and I would rather a homeowner check it than wonder.

Frequently Asked Questions About SB 342 and License Lapses
Does SB 342 affect my home patio or fireplace project?
No. Private residential work on property of 25 units or fewer was carved out, so the existing section 7031 rule still applies to your project exactly as it did before January 1, 2027.
What counts as a license lapse?
A lapse is any stretch where the license is not active. Common causes are a missed renewal, a bond that was not kept in place, or a workers compensation certificate that expired. It can happen to an otherwise solid contractor, which is why re-checking mid job is worth the five minutes.
I manage a small apartment building. Which rule applies to me?
That depends on the unit count and project type, and the line sits at 25 units. Private residential property at or under that threshold stays under the old rule. Multifamily above it falls into the categories SB 342 covers. For anything near the line, have your attorney read the project specifics before you sign.
Does a licensed mason mean I will not have workmanship problems?
It does not. Licensing is a floor, not a ceiling. On the Peninsula, most failures I get called out to trace back to base preparation and drainage, not paperwork. Salt air and moisture cycling here are hard on mortar, and the way joints fail in this climate has more to do with material choice and workmanship than with license status.
Should I ask for license and insurance proof in writing?
Yes, and homeowners here do it regularly. One recent request for a damaged block wall repair listed the scope in detail and closed by asking for license and insurance confirmation. That is a reasonable ask on any job, residential or commercial.
