A sub's CSLB license was suspended or expired mid-job: what California GCs should do

Short answer

CSLB says you can't actively contract with an expired, inactive or suspended license. CSLB also says work done during a bond suspension is considered unlicensed.
Common causes are a lapsed workers' comp policy, a canceled bond, an unpaid judgment or a missed renewal.
Under B&P §7031, a contractor generally can't sue to get paid unless licensed the whole time the work was done, and whoever paid an unlicensed contractor can sue to get the money back.
Pause the sub's work, save a dated copy of the record, ask the sub why, and talk to your lawyer before you pay for work done during the gap.

Why it matters

You checked the license before the sub started. It was Active. Three weeks later it isn't. That happens, and it changes your risk on the job. Under B&P §7031, a contractor generally can't sue to collect pay for licensed work unless they were licensed at all times while doing it. And whoever used an unlicensed contractor can sue to get back what they paid. A license that lapses mid-job can put payments for that stretch of work in dispute.

Your own license is in play too. Contracting with an unlicensed contractor is a cause for CSLB discipline (B&P §7118). See risks of hiring an unlicensed sub.

What the CSLB statuses mean

Active. CSLB defines it as licensed and able to perform work (CSLB terms).
Expired. A license that hasn't been renewed. Active licenses expire every two years. CSLB says work done while a license is expired counts as unlicensed work (CSLB renewal information).
Inactive. Still licensed, but not allowed to perform work (CSLB terms).
Suspended. CSLB's renewal page says you can't actively contract with an expired, inactive or suspended license (CSLB).

Read the whole record, not just the status line. It usually says why, and the reason tells you how quickly the sub can fix it.

Common reasons a license is suspended

CSLB lists these among the main reasons (CSLB, suspended licenses):

Workers' comp. The insurer canceled the policy, the policy expired, or the contractor has no comp and hasn't filed an exemption. By law, failing to keep required workers' comp suspends the license automatically, effective the date coverage lapsed (B&P §7125.2). The law requires CSLB's notice to explain that a pending suspension may show on the record for up to 45 days before the suspension periods are posted.
Bond. The surety canceled the contractor's bond, or a judgment or paid claim reduced it. CSLB says any work performed while the license is under a bond suspension is considered unlicensed (CSLB, bond suspensions). See the contractor's license bond.
An unpaid civil court judgment that isn't resolved in time.
A qualifier who left and wasn't replaced within 90 days.
Discipline for a violation of contractors' law.

Can the gap be fixed after the fact?

Sometimes, and it depends on the cause. Check the official source for the sub's situation:

Expired license. CSLB says the registrar must reinstate an expired license retroactively if a complete renewal application and fees arrive within 90 days of the expiration date. Later renewals run from the date CSLB receives them, which leaves a break (CSLB renewal information).
Bond suspension. CSLB may lift a bond suspension retroactively in some cases, for example when a late bond was caused by circumstances beyond the licensee's control (CSLB).
Workers' comp suspension. The license can be reinstated once the contractor shows proof of compliance (B&P §7125.2).

Section 7031 also has a narrow "substantial compliance" exception for a contractor who was licensed before, acted reasonably and in good faith to stay licensed, and fixed the problem promptly. A court decides that at a hearing. Don't count on it. Ask your lawyer.

What to do, step by step

Save the record now. Take a dated screenshot or PDF of the CSLB record from CSLB's Instant License Check or Sub Check. Note the status, the reason and any dates shown.
Pause the sub's work. Don't let them keep working on your job until the license shows Active again.
Call the sub and ask why. A missed renewal or a late bond can sometimes clear quickly. Ask for paperwork: the renewal receipt, the new bond, or proof of comp.
Check workers' comp right away. If the cause is comp, the sub's crew may have been working without coverage. Under Labor Code §2750.5, someone doing licensed work needs a valid license to count as an independent contractor. Call your own insurance agent.
Hold payments and talk to your lawyer. Before you pay for work done during the gap, get advice on your subcontract and §7031.
Write it down. When you found it, who you talked to and what they said.
Check again before restarting. Look the license up again the day the sub returns. Save that copy too.
Have a backup. If it won't clear soon, you may need another licensed sub in the right classification.

Common questions

Can a sub keep working while the license is suspended?

CSLB says you can't actively contract with an expired, inactive or suspended license, and that work done during a bond suspension is considered unlicensed. Pause the work until the record shows Active.

Do I have to pay a sub for work done while their license was suspended?

That's a legal question for your lawyer. Under B&P §7031, a contractor generally can't sue to collect pay for licensed work unless licensed the whole time, and whoever paid an unlicensed contractor can sue to get it back. There is a narrow substantial-compliance exception a court decides.

What does "Inactive" mean on a CSLB record?

CSLB defines it as a license that is still held but isn't permitted to perform work. An inactive license doesn't need a bond or workers' comp, and the contractor has to reactivate it before doing work.

If a sub renews an expired license, is the gap erased?

CSLB says an expired license is reinstated retroactively if a complete renewal application and fees arrive within 90 days of expiration. Later renewals leave a break. Check the record for the dates.

How often should I check a sub's license during a job?

Before they start, before each payment, and when a workers' comp policy or the license itself reaches an end date. Save a dated copy each time.
