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.
