Frequently Asked Questions
What is the #1 mistake California contractors make when filing mechanics liens?
Missing the 20-day Preliminary Notice deadline under Cal. Civ. Code § 8200. Every sub-tier claimant (subcontractor, supplier, equipment lessor, design professional NOT in direct contract with the owner) must serve the notice on the owner, direct contractor, and construction lender within 20 days of first furnishing labor or materials. Late notices have rolling-cure protection under § 8204 but only protect work within 20 days BEFORE the notice was served. Missing the deadline entirely or serving a defective notice (wrong form, wrong recipients, wrong service method) bars mechanics lien, stop notice, AND payment bond rights — the single largest cause of California construction-payment recovery losses.
Why does the California Notice of Completion matter so much to unpaid contractors?
Under Cal. Civ. Code § 8182, property owners record a Notice of Completion within 15 days after substantial completion to SHORTEN the Claim of Lien recording deadlines under § 8414. Direct contractors get 60 days from the Notice (instead of 90 days from completion); sub-tier claimants get only 30 days (instead of 90 days). A recorded Notice of Completion is the owner's most powerful defensive tool against unpaid contractors. Unpaid contractors must monitor the county recorder regularly after substantial completion — a recorded Notice of Completion silently triggers the accelerated 30- or 60-day clock and many contractors miss it until the recording deadline has already passed.
What is a California § 8480 Demand to Commence Action and why should I worry about it?
Cal. Civ. Code § 8480 allows a property owner to serve a written "Demand to Commence Action" on a mechanics lien claimant — typically when the owner needs to clear title for a sale, refinance, or new financing. After service, the claimant has only 60 days to commence the foreclosure action in California Superior Court, far shorter than the natural 90-day deadline under § 8460. Failure to file within 60 days makes the lien unenforceable. If you have a recorded California Claim of Lien and the owner serves a § 8480 demand, you must act immediately — there is no extension and no negotiation that resets the 60-day clock.
What is the California "double payment" doctrine and how does it help unpaid sub-tier contractors?
California is a "double payment" jurisdiction under Cal. Civ. Code § 8400 et seq. — sub-tier claimants (subcontractors, suppliers) can lien the property even when the owner has paid the general contractor in full. The owner's only protection against the double-payment exposure is obtaining proper conditional and unconditional lien waivers (Cal. Civ. Code §§ 8132-8138) from each sub-tier claimant at every progress payment and final payment. If the owner failed to collect sub-tier waivers, unpaid sub-tier claimants can recover from the property via mechanics lien foreclosure even if the GC was paid in full. This is one of the strongest claimant-side protections in U.S. construction-payment law.
What contents are required on a valid California Claim of Lien?
Under Cal. Civ. Code § 8416, a California Claim of Lien must be verified by the claimant under penalty of perjury and contain: (1) the demand amount after deducting just credits and offsets; (2) name of the owner or reputed owner; (3) general statement of the kind of work, services, equipment, or materials furnished; (4) name of the person who employed or hired the claimant; (5) description of the property sufficient for identification, including legal description if known; (6) verification signature; (7) mailing of a copy to the owner within 30 days of recording to preserve attorney's fees under § 8416(c). Defective Claims of Lien missing required content are unenforceable — strict statutory compliance is required.
How long do I have to file a foreclosure suit on my California mechanics lien?
Cal. Civ. Code § 8460 gives the claimant exactly 90 days from the recording of the Claim of Lien to commence a foreclosure action in California Superior Court. This is a statute of repose and cannot be tolled, extended by agreement, or excused for hardship. The deadline can be shortened to 60 days if the owner serves a § 8480 Demand to Commence Action. If the deadline is missed, the lien expires automatically by operation of law and the property owner can record a release. Most California mechanics lien losses come from missed § 8460 deadlines, not from denied claims on the merits — disciplined deadline tracking is the determinative factor.
