What this means in practice

Deadlines often differ by role. The period for a general contractor who dealt directly with the owner can be different from the period for a subcontractor or supplier, and residential projects can have their own rules. Check which category fits before relying on a single number.

The event that starts the clock matters as much as the length of the period. Depending on the statute, it can be the last day labor or materials were furnished, completion of the project, or the recording of a notice of completion or commencement by the owner. Keeping dated records of the last work performed helps establish the start date.

Recording a lien is not the end of the process. If the debt is not paid, the claimant generally has to file a lawsuit to foreclose the lien within the enforcement period, or the lien expires. When the debt is paid, the owner will usually want a signed lien release recorded so the title is clear.

General information, not legal advice. Laws change, and cities can add their own rules, so check the current statute before you rely on it.
