  • Fire systems

Helpful Inspection Information

  • Inspection Process: Once your building permit is issued, use the inspection record you received at permit issuance to be your guide to inspection scheduling. Remember to keep the permit, inspection record, and all required documentation on-site and available for all inspections, including full-sized approved plans.
  • Schedule an Inspection Online at (MBP). If for some reason the MBP website is down (unexpected outage), please call our customer service center at (425) 388-3311 and if it is after hours, leave us a message with the permit number, inspection type, and date you would like the inspection.
    Please Note: All conditions must be met and all outstanding fees must be paid before you can schedule a final inspection on a Residential Building Permit. For example, associated Land Disturbing Activity (LDA), Driveway/Access/Culvert (D1), Trail (D4), Fire Systems (FSYS), and Flood Hazard (FH/FHZ) permits must be completed before you can receive final approval on a Residential Building Permit. For Commercial Building Permits, refer to the conditions on your permit. 
  • Contact your Inspector
  • Inspection Status is available online at MBP under Today's Inspections.
