Tenant Improvement Blueprint

Permit Required

Tenant improvement permits are required any time a commercial tenant space is altered. This includes but is not limited to adding, removing and moving walls. If you are not sure if you require a permit, please contact the Permit Center at 425-837-3100.

Submittal Overview
  1. Gather all documents as required per the Tenant Improvement Submittal Requirement Packet (see below)
  2. Save all documents in PDF format per the Electronic Plan Requirements
  3. Visit to MyBuildingPermit.com to apply

Application Steps

We process tenant improvements as a combo permit, meaning all mechanical, plumbing and building permits are combined into one application and permit. If you are a plumbing or mechanical sub-contractor, please make sure your plans were included in the tenant improvement building permit set. Contact the Permit Center if you are not sure.
