Is Planning Your ADU in Austin Feeling Overwhelming?
If you’re a homeowner in Austin trying to figure out how to add an accessory dwelling unit to your property, you’re likely running into more questions than answers before you’ve even broken ground.
Zoning Rules and Permit Requirements Feel Like a Maze
Austin's ADU regulations involve setbacks, lot coverage limits, and utility connection requirements that can stall your project before it starts.
Finding a Builder You Can Actually Trust Is Harder Than It Sounds
Many contractors take on ADU projects without the specialized experience needed to navigate Austin's permitting process or deliver a finished unit that adds real value.
The Cost and Timeline Uncertainty Keeps You Stuck
Without a clear picture of what your ADU will cost or how long it will take, it's difficult to commit - and easy to put the project off indefinitely.
Prime Construction & Remodeling works with Austin homeowners every day to cut through exactly this kind of uncertainty, bringing local expertise and honest guidance to every stage of your ADU project.

How Much Does an ADU Cost in Austin?
Most ADU projects in Austin fall between $150,000 and $350,000, though the final number depends on the size of the unit, the finishes you choose, and the condition of your existing lot. A garage conversion typically costs less than a detached, ground-up build, and second stories or high-end finishes will move the estimate higher.
