California Notice Deadlines — A Quick Reference

Missing a notice deadline in California can forfeit your right to payment. These are the critical dates every California contractor needs to know.

4 min read

California construction law is unforgiving with deadlines. Miss one and you can permanently lose payment protections that took months of work to earn. The dates below apply to private projects — public project deadlines differ.

Preliminary Notice — 20 days

Serve your preliminary notice within 20 days of first furnishing labor or materials. If you miss this window, a late notice only protects work done in the 20 days before the late notice was served. Everything before that window loses lien protection.

Mechanics Lien — 90 days (or 30 days)

Record your mechanics lien within 90 days after completion of the work of improvement. If the owner records a Notice of Completion or Notice of Cessation, this window shrinks to 30 days for subcontractors. Check the county recorder's office regularly on active projects.

Enforce the Lien — 90 days after recording

After recording your mechanics lien, you must file a lawsuit to enforce it within 90 days. If you don't file suit in time, the lien expires and becomes unenforceable.

Stop Payment Notice

Can be served at any time before the owner or lender has disbursed funds. Most effective early — once money has been paid out, a stop payment notice has less impact.

Payment bond claim — Little Miller Act

On public projects, serve notice of your bond claim within 30 days of recording a stop payment notice, or within 6 months after you last provided labor or materials.

The safest approach

Treat preliminary notices as standard operating procedure — send one on every private project, every time, on day one. Build it into your project startup checklist so it never gets missed.

Deadlines can vary based on project type, contract terms, and specific circumstances. This is a general reference for educational purposes only, not legal advice. Consult a California construction attorney for guidance on your specific situation.
