The Smalley
Rough estimates for the plans on this site — not prices of ADUs we have built or sold. Estimate for a typical Austin site. Finishes, site conditions, and neighborhood- and city-level policies that apply to a specific parcel can all move this figure significantly. A site survey is the only way to an accurate number.

Common questions
How long does it take to build?
We're still gathering data points on how quickly we can build adus, but on average 6-9 months.
I understand the code has changed in Austin regarding how big ADUs can be – can you summarize the current regulations?
The previous land development code - which one can still develop under - limited ADUs to 0.15 FAR (FAR = floor-to-area ratio - floor area of your structure as compared to the size of your lot) or 1100 square feet, whichever is smaller. For instance, if you had a 6000sf lot, your ADU would be limited to 900 square feet.
With the addition of the HOME Amendment Phase 1, landowners have a lot more options regarding secondary and now tertiary structures. In practical terms, the new limit for a single structure is .4 FAR or 2300sf, whichever is larger.
Does your ADU service include design/build or construction management services?
Because ADU is a design-build company we can offer services from concept to keys. Wherever you are in the process - whether it be in the design phase or whether your project is permitted and ready for construction - ADU can help you reach your goals with your ADU build.
General information, not legal or code advice — Austin’s rules change, and what applies to your lot depends on the property. Ask us or the City for specifics.
