In Washington state, you must file a mechanics lien within 90 days after the last work was performed or materials were supplied. If you sent a pre-lien notice, that timeframe may change.
Key points
- 90-day deadline from last work or materials provided.
- Pre-lien notice can affect timing.
- File in the county where the project is located.
