Your Legal Rights Under California Mechanics Lien Law

California Civil Code §8000 et seq. gives contractors, subcontractors, and suppliers powerful tools to collect unpaid amounts — and gives property owners equally strong defenses against improper liens.

Rights of Contractors, Subcontractors & Suppliers

If you performed work or supplied materials on a California construction project and were not paid, you have constitutional and statutory lien rights. California's mechanics lien law is one of the most contractor-friendly in the nation.

Critically, subcontractors and suppliers have independent lien rights against the property even if the property owner already paid the general contractor. This is a defining feature of California lien law and protects the downstream payment chain.

Rights of Property Owners

If a mechanics lien has been filed against your property — or if you're concerned one might be — you have strong legal options. Not every lien is valid, and even a valid lien may have procedural defects that can be exploited.

Property owners can also protect themselves proactively by requiring conditional and unconditional lien waivers at each payment milestone and by verifying that all subcontractors have been paid before releasing final payment to the general contractor.

Critical Deadlines

Note on the foreclosure deadline: Once you file a mechanics lien, you generally have 90 days to file a lawsuit to foreclose the lien (or reach a written agreement extending this period). Failure to foreclose within this window releases the lien automatically. However, if the owner records a Notice of Completion or Notice of Cessation, the deadline to file the lien itself may be shortened — to 60 days for direct contractors and 30 days for subcontractors and suppliers.

Preliminary Notice Requirements

The 20-day preliminary notice is a prerequisite to lien rights for most subcontractors and suppliers. It must be served on the property owner, the general contractor, and the construction lender (if any) within 20 days of first furnishing labor or materials.

Failure to serve a timely preliminary notice does not completely extinguish lien rights — but it does limit them. Without a proper preliminary notice, a subcontractor can only lien for work performed in the 20 days before the notice was actually served.

Direct contractors (those with a contract directly with the property owner) are exempt from the preliminary notice requirement.

Available Remedies

California law provides multiple parallel remedies for unpaid contractors and suppliers. These can often be pursued simultaneously:

• Mechanics Lien: A lien against the real property that can force a sale to satisfy the debt.
• Stop Payment Notice: A notice to the construction lender requiring it to withhold funds from the borrower equal to the unpaid claim.
• Payment Bond Claim: On public projects and many private projects, contractors must post a payment bond. Subcontractors can make claims directly against the bond.
• Civil Lawsuit: Breach of contract, quantum meruit (value of services rendered), and prompt payment penalty claims can all be pursued in superior court or small claims court.
