Why it takes this long
- 57% of finished jobs passed final inspection within 90 days of the permit.
- Of the 291 permits issued from September 2022 to September 2024, 144 (49%) had no final inspection on record by September 2026. They may still be under way, dropped or never inspected; the records do not say which. They are left out of the build time; any of them that finishes will have taken more than two years, so counting them would make the typical time longer.
- The permit wait is not shown: 4 permits with both dates, under 30.
Days are counted between the dates on each city permit: applieddate, issueddate, completeddate. Median and middle half: half of the jobs took longer than the median; the middle half runs from the 25th to the 75th percentile. A figure is shown only when it rests on 30 or more permits. Kinds of work are sorted by the same rules as our contractor lists. Source: Seattle Building, Electrical and Trade Permits (data.seattle.gov 76t5-zqzr, c4tj-daue, c87v-5hwh), read 2026-09-24.
