Building inspection process

March 2009 notice to all residential building permit holders: Permitting Department 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. Permitting Department 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 Permitting Department. A map and directions to Permitting Department 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.

  • The Inspection Voice Request Brochure User's Guide (PDF*, 43KB) gives detailed instructions.

Building Inspection requests received before 3 p.m. on a workday can be scheduled for inspection the following workday. Request for fire inspections will receive a return call the next business day to schedule a specific date and time for the inspection.

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. Failure to provide these documents can result in no inspection and may incur a re-inspection fee.
