Austin Granny Flats & In-Law Suites
Close enough to help. Separate enough to live independently.
A granny flat, or in-law suite, is the middle path between multigenerational living under one roof and moving a parent across town. We tailor any plan below for aging in place during design.

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.
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.
