The Building Department retains historic building permit records that exceed the requirements of the Washington State Archives, Office of the Secretary of State records retention schedule.
All permit records were kept from as far back as the 1950s. Most residential building plans were not kept past the required 6-month retention period after the project was completed.
The Building Permit Office scanned in all permits up to 2018 and are available upon request. All other permits and their supporting documentation dated after 2018, can be accessed through our online permit portal by putting in the address. Advanced searches of permit types, date ranges and such can be performed under the advance search tab.
