Frequently Asked

Are ADUs legal in Austin, Texas?

InvestmentBy Laurel Seymour

Quick Answer

Yes. ADUs (accessory dwelling units) are legal in Austin and permitted on most single-family lots within the city limits. Austin's HOME initiative (adopted 2023–2024) significantly expanded ADU eligibility by removing the owner-occupancy requirement, reducing minimum lot sizes, and relaxing setback rules. In 2026, both detached and attached ADUs can be built on eligible properties, and both the main home and the ADU can be rented simultaneously.
