What Happens When a General Contractor Fails to Pay a Subcontractor in California?

Getting paid is important, so what happens if a general contractor fails to pay a subcontractor? California laws protect against these kinds of issues, but non-payment can also have practical effects that ripple throughout a project. Knowing the potential consequences and how to handle them is key to protecting your rights.
At Plumtree & Brunner, LLP, our California construction lawyers help you deal with non-payment issues to subcontractors and beyond. Protect your investment, your business, and your license with a skilled legal team by your side.
Why General Contractors Fail to Pay Subcontractors
Nonpayment can happen for many reasons, including:
- The owner has not paid the general contractor
- The GC disputes the subcontractor’s work or invoices
- Cash‑flow problems or mismanagement within the GC’s business
- Change‑order disagreements
- Delays, defects, or scope conflicts
- Intentional withholding to pressure the subcontractor
Regardless of the reason, California law does not allow general contractors to simply ignore payment obligations. Once payment is late, subcontractors gain access to powerful remedies.
California’s Prompt Payment Laws Apply
California has strict prompt‑payment statutes that require general contractors to pay subcontractors within a specific timeframe after receiving payment from the owner. A GC must pay a subcontractor within 7 days of receiving funds for that subcontractor’s work.
If the GC fails to pay:
- The subcontractor may be entitled to 2% monthly interest on the unpaid amount.
- The GC may face disciplinary action from the Contractors State License Board (CSLB).
- The subcontractor can pursue civil remedies, including breach‑of‑contract claims.
These rules apply even if the GC claims the owner has not paid, unless the subcontract specifically allows conditional payment terms, which California courts scrutinize closely.
Subcontractors Can File a Mechanic’s Lien
One of the strongest tools available to subcontractors is the mechanic’s lien. If the GC fails to pay, the subcontractor can record a lien against the property to secure the unpaid amount.
A mechanic’s lien places pressure on both the GC and the property owner, because the lien clouds title and can halt refinancing or sale. Owners often demand that the GC resolve the issue quickly to clear the lien.
Stop Payment Notices
Subcontractors can also file a stop payment notice, which freezes funds before they reach the general contractor. This remedy is especially effective on public works projects, where mechanic’s liens are not allowed.
A stop payment notice:
- Directs the owner or lender to withhold funds from the GC.
- Ensures money is set aside to pay the subcontractor once the claim is resolved.
- Can significantly disrupt the GC’s cash flow, prompting faster resolution.
On private projects, a bonded stop notice can reach construction loan funds, adding even more leverage.
The Subcontractor May Sue the General Contractor
If informal negotiation fails, subcontractors can pursue litigation. Common claims include:
- Breach of contract
- Quantum meruit (payment for the value of work performed)
- Prompt‑payment penalties
- Unfair business practices
- Claims against the GC’s license bond
Impact on the Project and the Owner
When a GC fails to pay a subcontractor, the consequences extend beyond the two parties:
- Work may stop, causing delays.
- The owner may face liens, even if they already paid the GC.
- Other subcontractors may become nervous, increasing the risk of additional claims.
- Lenders may freeze disbursements, slowing construction progress.
Owners often intervene quickly to avoid liens, stop notices, and schedule disruptions.
How General Contractors Can Mitigate Damage
If a GC has failed to pay a subcontractor, immediate action can reduce legal exposure:
- Communicate openly with the subcontractor.
- Resolve invoice disputes quickly.
- Release payment as soon as funds are available.
- Document all communications and change‑order issues.
- Avoid retaliation or threats, which can escalate the dispute.
Protecting Yourself as a Subcontractor

Subcontractors should take steps early to protect their rights:
- Serve preliminary notices on every project.
- Track payment deadlines carefully.
- Document work performed and communications.
- Use mechanic’s liens or stop notices promptly when payment is late.
- Consult a construction attorney if the GC continues to delay.
