Lien Lawaka: NOCaka: notice of substantial completion

Notice of Completion

In Plain English

A document filed when a project is finished that shortens the time remaining for others to file liens.

Definition

A notice of completion is a document recorded by the property owner after a construction project is substantially complete that triggers shortened deadlines for subcontractors and suppliers to file mechanic's liens. In California, for example, recording a notice of completion reduces the lien filing deadline for subcontractors from 90 days to 30 days after the notice is recorded. Not all states recognize or require this document.

Why It Matters in Bidding

A recorded notice of completion can sharply compress the window subs and suppliers have to file a mechanic's lien, so unpaid lower-tier parties must move fast once it appears. For estimators and credit managers, tracking project completion status feeds collection timing and the cash-flow assumptions baked into a bid's overhead and financing costs.

Example

After a California office tenant improvement wraps up, the owner records a notice of completion, and the electrical sub's accounting team, still owed retention, files its mechanic's lien within the shortened deadline rather than assuming it had the full standard period.

Frequently Asked Questions

Recording it generally shortens the time subcontractors and suppliers have to file a mechanic's lien. In California, for example, the subcontractor deadline drops from 90 days to 30 days after recording. Claimants who are still owed money must monitor for the recording and act quickly to preserve lien rights.
The property owner typically records it after the work is actually or substantially complete, within the period set by state statute. Recording too early or improperly can render it invalid, which is why the document's validity is sometimes contested when a lien deadline turns on whether it was properly filed.
No. It is recognized in some states, such as California, but not all jurisdictions require or even allow it. Because the document and its effect on lien timing are state-specific, contractors and suppliers should confirm the governing state's lien statute rather than assume the mechanism exists everywhere.
