FAQ

Frequently Asked Questions

Find answers below regarding our custom pool construction, engineering standards, and preconstruction phases.
Can I build up to three units on my property in Austin, Texas?

Yes. This is because of Phase 1 of the HOME initiative in Austin, which allows single-family homes zoned SF-1, SF-2, and SF-3 to build three units by-right. Compliance with these new rules will require expert ADU construction in Austin, so your project remains within the maximum building coverage limitations.

You can legally utilize ADUs in Austin, TX, for long-term leasing without any restrictions. However, for short-term rentals such as Airbnb, according to the city’s regulations, secondary structures that were constructed after 2015 cannot be leased for more than 30 days in a year, and an STR permit is required.

Not always. While standalone ADUs in Austin, TX historically required individual utility hookups, units built with only one bathroom can often share the primary home’s water line. Experienced ADU building contractors will evaluate your specific lot layout to minimize municipal utility connection costs.

Austin’s updated zoning rules have eliminated the old 10-foot structural separation requirement between primary homes and secondary units. However, your ADU construction in Austin must still comply with the International Residential Code (IRC) fire safety standards, which dictate specific fire-rated wall protections if units are built close together.

This depends on how complicated the design is, how much engineering work is involved, and how quickly we can get permits. Normally, a custom installation will take about eight to twelve weeks after the start of excavation. As part of our preconstruction process, we give you an itemized project schedule from first dig to final fill.

First, verify your lot’s zoning and check for any neighborhood deed restrictions. Then, hire specialized ADU building contractors to pull architectural plans, request a unique secondary address from the city, and submit a New Construction Permit Application through Austin’s Residential Plan Review department.
