Red Flags a GC or Owner Won't Pay — Protect Your Lien Rights
Most payment disputes in California construction are predictable. These warning signs appear before or during a project — recognize them early and take protective action while your preliminary notice and lien deadlines are still open.
Red Flag #1: No written contract — or a vague one
A property owner or GC who resists a written contract, or insists on a contract with no clear payment schedule, is a significant risk. California law allows oral contracts but they are difficult to enforce. Always get it in writing, including scope, price, and payment terms.
Red Flag #2: Requesting to start before the contract is signed
"Just get started and we'll sign the paperwork later." This is how payment disputes begin. Never commence work until the contract is executed and any required permits are obtained. Serve your preliminary notice the day you start.
Red Flag #3: Slow or excused payments on early draws
How a party pays on the first draw predicts how they will pay on all subsequent draws. Unexplained delays, partial payments, or requests for "just a little more time" on early invoices are serious warning signs. Verify the project's financing if you can.
Red Flag #4: Unusually low bids accepted from other subs
If the GC accepted a bid from another sub that is clearly below market cost, that sub may be set up to fail — and their non-payment dispute will delay your payment. Ask GCs about their subcontractor vetting process.
Red Flag #5: Owner is actively trying to sell the property
A property owner who is mid-sale while a project is underway has strong motivation to delay payment until closing — and may disappear after the sale closes. Record a preliminary notice on day one and consider recording your lien earlier rather than later.
Red Flag #6: No response to payment inquiries
If calls and emails go unanswered when payment is due, do not wait. Silence is not a payment dispute — it is a collection problem. Send a formal demand letter immediately and begin preparing your mechanics lien.
Red Flag #7: Disputing scope or quality after work is complete
A party who raises no concerns during the project but suddenly claims defective work or out-of-scope additions when the invoice arrives is a red flag. Maintain detailed contemporaneous records — photos, daily logs, signed change orders — that document the work as performed.
Red Flag #8: GC asking for unconditional lien waivers before payment clears
A GC who routinely asks subcontractors to sign unconditional lien waivers in exchange for a check (rather than after the check clears) is either uninformed or manipulative. Never sign an unconditional waiver until payment has confirmed in your account.
Red Flag #9: Project ownership is unclear or recently changed
Properties that have recently changed hands, are in trust, or have LLC or entity ownership structures can create complications for lien filing and enforcement. Verify the correct legal owner before starting work — the property records are public.
Red Flag #10: GC has prior CSLB complaints or lawsuits
Check the CSLB license lookup at cslb.ca.gov for the GC's license status, any disciplinary history, and any prior complaints. Also run a court record search. A pattern of payment disputes is the strongest predictor of future non-payment.
What to Do If You See These Signs
- Serve your preliminary notice immediately if you have not already
- Stop performing additional work until outstanding invoices are paid
- Send a formal demand letter in writing
- Prepare your mechanics lien — do not wait until the deadline is imminent
- Consult an attorney before the lien deadline passes
