Building inspections

Building inspection process

March 2009 notice to all residential building permit holders:  DDES is re-implementing inspection for energy conservation and ventilation and indoor air quality (VIAQ) measures.  See Energy and Ventilation Required Inspections (PDF*, 26KB) for more information.

  • Permit approval notification. DDES permit customers are notified via U.S. mail when their building permit has been approved. The notification includes information about any outstanding fees or other conditions that may be required prior to issuance.

  • Permit issued. Once all of the requirements specified in the notification have been met, the permit may be picked up at DDES. A map and directions to DDES are available online.

  • Schedule inspection. After receiving the permit, customers will need to request a building inspection or, if required, a preconstruction conference.

    Preconstruction conferences. A preconstruction conference is required for all commercial and multifamily projects.

    A preconstruction conference also may be required for projects with significant site and building issues such as wetlands, shorelines, floodplain, geotechnical, steep-slope, erosion hazard, drainage, excavation near a property line, etc.

    A notice and condition will be added to the permit package if a preconstruction conference is required.

    When requesting a preconstruction conference online or by phone, please allow up to two working days for the conference to be scheduled.

Scheduling building and new construction fire inspections

Building inspection requests for unincorporated King County can be made 24 hours a day, 7 days per week by either of the two following options.  Note:  For building and new construction fire inspections only.  Other agencies do plumbing and electrical inspections.

Inspection requests received before 3 p.m. on a workday can be scheduled for inspection the following workday.

Approved plans must be on-site. It is the responsibility of the applicant and contractor to have the approved plans on the job site and to make inspection requests at the appropriate time and after any required approvals - such as plumbing and electrical inspections - have been completed.

How to contact a building inspector

DDES building inspectors are available via telephone from 7 to 8:30 a.m., Monday through Thursday, and can be reached by calling 206-296-6630.
