Can you build 3 homes on a lot in Austin? Yes, and the lot can be small.

Yes. Under HOME Phase 1, up to three homes are allowed on a single-family lot in Austin, on the SF-1, SF-2, and SF-3 zoning districts that cover most houses in the city. This has been in force since applications opened on February 5, 2024. The three units can include a tiny home of 400 sq ft or less. You still have to meet the building rules for height, setbacks, and lot coverage, but you no longer need a rezoning to add the second and third home.

HOME stands for "Home Options for Mobility and Equity," the City of Austin's name for its 2023–2024 housing reforms (some press also calls it "Home Options for Middle-income Empowerment"). It came in two phases. Phase 1 lets owners build up to three homes on a single-family lot. Phase 2 cut the minimum lot size so lots can be split into smaller parcels. Together they are the biggest change to Austin single-family zoning in decades.

As small as 1,800 sq ft. HOME Phase 2 cut the minimum lot size from about 5,750 sq ft (a standard that had stood for roughly 80 years) down to 1,800 sq ft, effective August 16, 2024. This is the change that lets owners split a larger lot into more parcels. For example, an 8,000 sq ft lot can now be divided into roughly four separate parcels, each able to hold its own home. This lot-subdivision path is what makes HOME different from a simple "add more units" rule.

No. This is a common myth, and it is wrong. A December 12, 2023 ruling by Judge Jessica Mangrum (Acuña v. City of Austin) voided three OTHER 2022 ordinances (Vertical Mixed Use 2 (VMU2), Residential in Commercial, and Compatibility) because the city had not followed proper notice and protest-rights steps. HOME was not one of those three ordinances. HOME passed the City Council separately, by a 9–2 vote, and both Phase 1 and Phase 2 have been continuously in force. No court has struck HOME down.

Usually no. Austin removed its minimum parking requirements citywide in November 2023, so a home built under HOME generally carries no parking mandate. You can still build parking if you or your tenants want it, but the city no longer forces you to. On a small lot this matters a lot. A required parking pad can crowd out the space you need for a third home or a lot split, so removing the rule makes the small-lot math work far better.

Yes. Both HOME Phase 1 and Phase 2 are the operative zoning law in Austin in 2026. The City is actively processing applications: as of July 6, 2026 it had reviewed 829 applications, approved 657 of them, and approved 1,309 new homes in total. On May 8, 2026 the City Council voted 9–1 to refine some rules (lot width, side yards, and the subdivision process), but that is a refinement, not a repeal. The core rights to build three homes and to use the smaller lot size are intact.

As of the City's own data updated July 6, 2026, HOME had approved 1,309 new homes. That came from 657 approved applications out of 829 that had been reviewed. These figures are from the City of Austin Development Services page, which is the primary source and is updated as applications move through review. The approval rate, about 79% of reviewed applications, shows the program is functioning, not stalled.

Yes, by a wide margin so far. Looking at 2025 sales, 57 HOME homes sold at a median price of about $750,000, while 115 new homes built outside HOME sold at an average of about $1.58 million. That is roughly half the price. The reason is straightforward: HOME homes sit on smaller lots and are smaller buildings, so the land and construction cost per home is lower. This price gap is the main argument supporters use for keeping and expanding the program.

It voided three separate 2022 ordinances. The first was Vertical Mixed Use 2 (VMU2), which added height and density along some corridors. The second was Residential in Commercial, which allowed homes on commercially zoned land. The third was Compatibility, which had changed the height limits near single-family homes. Judge Mangrum found the city did not follow the required notice and protest-rights process for these three. HOME was passed through a different process and was never part of that case.

HB 24, passed by the Texas Legislature in 2025, raised the threshold for a valid zoning protest to 60% of affected property owners and removed some notice requirements. This matters because the legal theory that had threatened Austin's reforms rested on protest-rights and notice defects, the same kind of defect that sank the three 2022 ordinances. By raising the bar for protests, HB 24 weakened that line of attack, making it harder to challenge HOME or similar reforms on those grounds going forward.

Yes. When the City Council voted on HOME Phase 1 in December 2023, there were about 16,000 property-owner protests on the record. Under the old rules a protest of that size could have forced a supermajority vote or blocked the change. The Council adopted HOME anyway, by a 9–2 vote. This is part of why the myth that HOME was "struck down" spread. The fight was loud, but the protests did not stop it, and no court reversed it.

On May 8, 2026 the Council voted 9–1 to adjust three technical parts of HOME: minimum lot width, side-yard setbacks, and the process for subdividing a lot. These are fixes based on the first two years of real projects, not a rollback. City staff are expected to bring the detailed revisions back around December 2026. So far about 40 small-lot buildings and 6 lot subdivisions have advanced under Phase 2, and the refinements are meant to make those paths smoother, not to close them.

Yes, if your lot is large enough. Because HOME Phase 2 cut the minimum lot size to 1,800 sq ft, you can now subdivide a larger lot into several smaller parcels that each meet the minimum. As an example the City has cited, an 8,000 sq ft lot can be split into roughly four parcels. Each new parcel can then hold its own home, and the smaller parcels can also use the three-home allowance from Phase 1. The May 2026 refinements are partly aimed at making this subdivision process clearer.

Start with the City of Austin Development Services HOME amendments page, which is the primary source for the rules, the application process, and the live approval count. It links to the ordinance text and the application forms for both phases. Because the May 2026 refinements will change some technical numbers around December 2026, check that page for the current lot-width and side-yard rules before you plan. For your specific zoning district, look up your parcel in the City's property profile tool, which shows whether you are on SF-1, SF-2, or SF-3.
