FAQ

How do I know if construction is illegal?
Illegal construction usually lacks a posted permit, involves work after a stop-work order, or violates zoning/building regulations; if unsure, report it and L&I will inspect.
Can I remain anonymous when I file a complaint?
The city allows complainant confidentiality in many cases; check the intake options on the L&I report page for privacy details.
Will reporting stop the work immediately?
If the site presents an immediate safety hazard, L&I may issue a stop-work order and inspect; otherwise, the complaint enters the inspection queue.

  2. Submit the complaint using the L&I report page or call 311 to log the issue.
  3. Track the complaint number and follow up with L&I for inspection scheduling.
  4. If L&I issues penalties or orders, read appeal instructions and submit an appeal or correction plan within stated deadlines.
