Why it takes this long

  • 1% of permits were issued the day they were applied for, and 41% within 30 days (553 permits).
  • The time to final inspection is not shown: the city's permit data has no final inspection date.

Days are counted between the dates on each city permit: Date_Entered, Date_Issued. 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: Metro Nashville Building Permits Issued (ArcGIS Building_Permits_Issued_2), read 2026-09-24.
