When is the deadline to file a California mechanics lien?
The standard mechanics lien deadline in California is 90 days after project completion. However, if the property owner officially records a Notice of Completion, the deadline shortens to 60 days for direct contractors and 30 days for subcontractors. Missing these statutory deadlines typically invalidates your right to claim the property as security for unpaid work.
For Direct Contractors (Hired by the Owner)
If you hold a direct contract with the property owner, your deadline to file a claim is the earliest of the following two dates:
- 90 days after the entire work of improvement is officially completed; or
- 60 days after the property owner records a Notice of Completion or Cessation.
For Subcontractors, Suppliers, and Laborers
If you were hired by someone other than the property owner (such as a general contractor or another subcontractor), your filing deadline is significantly shorter if a notice is filed. Your deadline is the earliest of the following two dates:
- 90 days after the entire work of improvement is officially completed; or
- 30 days after the property owner records a Notice of Completion or Cessation.
20-Day Preliminary Notice Deadline
Before you can even consider your final recording deadline, you must meet the preliminary notice requirement.
- Deadline: You must serve a Preliminary Notice within 20 days of first providing labor or materials to the job site.
- Who must send it:
- Subcontractors, material suppliers, equipment lessors, and anyone without a direct contract with the property owner.
- Direct contractors must also send this notice to the construction lender, if one exists. (You can use a standard preliminary notice California PDF template to fulfill this requirement.)
PRO TIP: Filing Late Preliminary Notices
If you miss the 20-day window, you can still send the notice, but it will only protect the payment for work done in the 20 days preceding the notice and any work done thereafter.
Quick Table Summary: California Mechanics Liens Deadlines
The deadline to actually record your document with the California county recorder depends on two factors: your role on the project and whether the owner files a formal notice.
| Action | Who Must Comply | Deadline |
|---|---|---|
| Serve Preliminary Notice | Subcontractors, Suppliers, Laborers | Within 20 days of first furnishing labor or materials |
| Record Lien (No Notice of Completion) | Direct Contractors, Subcontractors, Suppliers, Laborers | 90 days after project completion |
| Record Lien (Notice of Completion Filed) | Direct Contractors | 60 days after notice is recorded |
| Record Lien (Notice of Completion Filed) | Subcontractors, Suppliers, Laborers | 30 days after notice is recorded |
| File Lawsuit to Enforce Lien | All Claimants | 90 days from the date you recorded your lien |

What Triggers the Start of the 90-Day Clock?
The clock begins ticking upon “actual completion” of the project. California law mechanics lien rules define completion as any of the following events:
- Actual completion of the work of improvement.
- The owner occupying or using the property, accompanied by a cessation of labor.
- A continuous cessation of all labor on the project for 60 days.
- The owner recording a Notice of Cessation after labor has stopped for a continuous 30 days.
The Enforcement Deadline: Filing the Lawsuit
Recording the document is not the final step. A recorded mechanics lien is temporary.
Deadline: You must file a lawsuit to foreclose on the property within 90 days of the date your lien was formally recorded by the county.
If you do not file a lawsuit or secure a formal extension within this 90-day window, the lien will expire and become void. At this point, the owner can demand that you record a California mechanics lien release to remove the expired claim from their property title.

FAQs: California Mechanics Lien Deadlines
Can I file a mechanics lien in California after 90 days?
No, you generally cannot file a mechanics lien in California after the 90-day deadline has passed. If you miss the statutory deadline, the county recorder may still physically file the document, but the lien itself will likely be invalid and unenforceable in court.
Do weekends or holidays affect the 90-day deadline?
Yes. The 90-day timeline is strictly calculated using calendar days. If your 90-day recording deadline or 20-day preliminary notice deadline falls on a weekend or a legal holiday, California law generally extends the deadline to the next regular business day. However, it is always safest to file before the weekend to ensure your rights are protected. File a Rush Lien with Northwest Lien Service →
What if I missed the 20-day preliminary notice deadline?
If you missed the 20-day preliminary notice deadline, you can still serve the notice late. However, your payment protections will be limited. A late notice will only protect your payment rights for work or materials provided in the 20 days immediately preceding the date you finally served the notice, plus everything provided afterward.

Does repairing defective work extend my recording deadline?
No, returning to the job site strictly to repair defective work or complete minor punch-list items generally does not extend your mechanics lien deadline. The clock starts ticking from the date the project was originally deemed substantially complete.
Can I extend the 90-day deadline to file a lawsuit?
Yes, you can extend the 90-day enforcement deadline, but ONLY IF the property owner agrees to sign a “Notice of Credit.” This document must be recorded at the county office before the original 90-day window expires, and it can extend your deadline to foreclose by up to one year from the project completion date.
