Why it takes this long

  • 0% of permits were issued the day they were applied for, and 6% within 30 days (668 permits).
  • The longer step is building and inspection: about 3 months for the permit against about 11 months from permit to final, at the median.
  • 8% of finished jobs passed final inspection within 90 days of the permit.
  • Of the 611 permits issued from September 2022 to September 2024, 86 (14%) 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.

Days are counted between the dates on each city permit: applieddate, issue_date, completed_date. 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: Austin Issued Construction Permits (data.austintexas.gov 3syk-w9eu), read 2026-09-24.
