Data through January 2025 · updated 19 Oct 2026
3,821 building permits were issued in the City of Auburn from February 2023 to January 2025, about 1,910 a year. HVAC permits lead with 1,642, then plumbing (665) and solar (170). 60% were for homes. The city's file names contractors, but the file has no job value, so we only count permits per firm and don't rate, rank or profile firms from it: these pages show what was built, where, when and how fast the city signed it off.
Building, mechanical, plumbing, side-sewer, demolition, fire-protection and sign permits issued by the City of Auburn for property inside city limits, in both its King County and Pierce County parts (Lea Hill, Lakeland Hills, West Hill and downtown). Electrical permits are issued by the Washington State Department of Labor & Industries and are not in this file. Unincorporated King County permits (the separate King County page) and neighbouring cities such as Kent, Federal Way, Algona and Pacific are not in this file. Street, utility, storm, grading and right-of-way permits are left out.
The permit file can't tell you who does good work. Ask for the contractor's license number and look it up at the Washington State Department of Labor & Industries, then ask the city whether they pulled the permit for your job.
Permits issued February 2023 through January 2025, every kind of work with 100 or more. Last 12 months on file is Feb 2024–Jan 2025. Homes is the share issued as residential permits.
