5,943 permits from 1,919 contractors across 10 kinds of work in the City of St. Louis, October 2023 through September 2026: about 1,981 a year. Remodel & Alteration is the biggest trade with 1,904 permits. The busiest month for filings is October.
Firms are distinct business names on the file. A linked usual filed value opens what that work costs. Finished is the share of permits a year or more old that the city closed out. Days to finish run from issue to the city's completion date, not from application.

The file we publish splits exactly into the last 12 months on file and the 24 months before them, so these are 12-month periods ending September 2026, not calendar years. Per year scales each period to 12 months. Counts cover the 10 kinds of home work we track, not every permit St. Louis issues.
| Period | Months | Permits | Per year |
|---|---|---|---|
| Oct 2023–Sep 2025 | 24 | 3,804 | 1,902 |
| Oct 2025–Sep 2026 (last 12 months) | 12 | 2,139 | 2,139 |

Source: City of St. Louis building permits. The window is October 2023 through September 2026; a permit filed after that isn't here yet.
A filed value is what the contractor wrote on the permit when they applied. It is not a quote and not the final bill.
Counts are permits, not jobs: one job can need several permits, and one permit can cover several visits.
