Counts are permits issued per calendar month as Bozeman 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.
How long do permits take in Bozeman?
Based on 240 Bozeman permits applied for between Nov 2023 and Aug 2026, the typical (median) permit was issued 161 days after application, and the middle half of permits took 100–259 days. One in ten took longer than 394 days.

| Residential building | 166 days | 118–314 days | 104 |
| Commercial building | 126 days | 85–184 days | 47 |
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. How we calculate approval times.
Housing law — Montana
Montana's SB 528 (2023, effective 2024) requires municipalities statewide to allow at least one accessory dwelling unit by right on lots with a single-family home; the 2023 housing-reform laws survived an early challenge when the Montana Supreme Court reversed a preliminary injunction against them in 2024, allowing them to take effect.
SB 323 (2023) requires cities of 5,000 or more to allow duplexes on lots where single-family homes are permitted, with no stricter standards than for single-family homes.
