Austin's Custom ADU Builders, Built for Real Budgets
An ADU is its own dwelling, not just an extra room – which means its own foundation, its own utilities, and its own permitting path separate from the rest of your home. As Austin’s custom ADU builders, we design every unit around your specific lot, whether that’s a detached backyard studio, a garage conversion, or a unit built above an existing garage.
Custom doesn’t mean expensive here. As one of the more affordable ADU builders in Austin, we run every project on a fixed-price contract, so the number we quote after design is the number you pay at closeout – no scope creep, no surprise change orders.
ADU Types We Build in Austin, TX
Detached Backyard ADU
A fully standalone unit in the backyard, with its own foundation, utilities, and entrance. The most common type for rental income or a fully private guest space. Current Austin rules allow this on most qualifying lots without a special variance.
Garage Conversion ADU
Converting an existing garage into a legal, livable ADU with a kitchenette and bathroom, not just a finished room. Often the fastest and most cost-effective path, since the structure and foundation already exist.
Above-Garage ADU
A second-story unit built above an existing or new garage, keeping the footprint small while adding a fully separate living space. Height and setback rules apply specifically here, and we handle that design work as part of the project.
Attached ADU
A unit built onto the main house with its own entrance, kitchen, and bathroom. Distinct from a simple room addition because it functions as an independent dwelling. A good middle ground between a detached unit and a full in-law suite.
Why Austin Homeowners Choose AW as their Custom ADU Builders

Frequently Asked Questions

Do I need to live on the property to build an ADU in Austin?
No. Austin removed its owner-occupancy requirement, so you can build and rent an ADU whether or not you live in the main house.
How big can an ADU be in Austin, TX?
Generally capped at the lesser of 1,100 square feet or 15% of the lot area, with a separate cap for second-story space. Exact limits depend on your lot and zoning.
Can I have more than one ADU on my property?
In many cases, yes. Austin's HOME Initiative allows up to three total dwelling units on many single-family lots, depending on lot size and zoning.
Can I use my ADU as a short-term rental?
ADUs built after October 1, 2015 are limited to 30 days of short-term rental use per year. Long-term rental has no such cap.
How much does an ADU cost to build in Austin?
Costs vary by type and size. A garage conversion typically costs less than a detached new-construction unit of the same size. As affordable ADU builders, and as Austin ADU builders who scope every job individually, we provide a fixed-price quote after your feasibility assessment.
How long does it take to build an ADU?
Permitting typically takes several weeks to a few months; construction runs an additional few months depending on type and size.
Are you licensed and insured for ADU construction?
Yes, fully licensed and insured in Texas, with all permitting and inspections handled by us.
