Counts are permits issued per calendar month as Austin 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. How we calculate approval times.
Housing law — Texas
Texas has no statewide zoning or ADU mandate, so accessory-dwelling rules are set city-by-city; a 2025 statewide ADU-by-right bill did not become law. Austin's HOME reforms now allow up to three units on most single-family lots.
Reform is local: Austin's HOME initiative cut minimum lot sizes and allowed more units per lot, while 2025 state laws eased lot-size minimums and commercial-to-residential conversions.
