Top ZIP codes by recent activity
Permit activity in Sioux Falls
Igni counted 11,944 permits issued in Sioux Falls over the last 12 months (Oct 2025 – Sep 2026) — down 3.4% on the 12,368 in the 12 months before. The forecast expects about 4,406 over the next 6 months.
The source's volume stepped up around July 2017 (×1.8) — likely a change in what the city publishes, so we don't compare year over year across it.
Forecast: Holt–Winters, typical error ±10% in backtests one to six months ahead. How we forecast
| Permit type | Last 12 months | Year over year | Forecast, next 6 months |
|---|---|---|---|
| All permits | 11,944 | Down 3.4% | ≈ 4,406 |
| Residential building | 3,904 | Down 2.8% | ≈ 1,345 |
| Commercial building | 1,063 | Up 23.6% | ≈ 455 |
| Trade (electrical, plumbing, mechanical) | 6,977 | Down 6.8% | ≈ 2,583 |
| ADU | 0 | —* | — |
* No year-over-year figure: the source's volume for this permit type stepped up within the last two years — likely a change in what the city publishes — so the two 12-month windows are not comparable.

Counts are permits issued per calendar month as Sioux Falls publishes them to its open-data feed — not a complete census; a change in what the city publishes moves them too. The current month is left out, and the most recent months are provisional. A forecast is a statistical estimate with a range, not a prediction for any project. Informational only.

Typical, not guaranteed: individual permits vary with project scope, application completeness and plan-review workload. Days are calendar days from application to issuance; applications still pending are counted as not-yet-issued rather than dropped. Informational only, not legal advice.
