2. Survey & Design: Hire a surveyor to map trees and impervious cover.
3. Financing: Explore HELOCs, renovation loans, or cash-out refinances.

The HOME (Home Options for Mobility and Equity) Initiative is a series of code amendments adopted by Austin City Council starting December 2023. It allows property owners to build up to 3 housing units on single-family zoned lots, removes parking requirements, and relaxes other restrictions to increase housing supply.
Under the HOME Initiative, any residential lot in Austin with at least 2,500 sqft can have up to 3 units. Key requirements include compliance with building coverage (40% max) and impervious cover (45% max) limits.
Under the HOME Initiative, there is no longer a size limit for ADUs. Previously, ADUs were capped at 1,100 sqft. Now, size is only limited by building coverage (40% max) and setback requirements.
No. The HOME Initiative removed parking requirements for additional units on single-family lots. You can build up to 3 units without providing any off-street parking.
The minimum lot size for a property with multiple units is 2,500 sqft. However, HOME Phase 2 (May 2024) also allows single-family homes on lots as small as 1,800 sqft.
