What is an ADU?
An Accessory Dwelling Unit (ADU) is a self-contained living space on the same property as your main home. ADUs can be:
Detached structures in your backyard
Garage conversions
Above-garage apartments
Attached additions with separate entrances
mart Reasons Austin Homeowners Choose ADUs
Rental Income
Generate $1,500-$3,000+ monthly from long-term or short-term rentals. Many ADUs pay for themselves in 5-8 years.
Multi-Generational Living
House aging parents or adult children while maintaining privacy for everyone.
Increased Property Value
ADUs typically add $150,000-$300,000 to your property value—often more than construction costs.
Home Office or Studio
Create a dedicated workspace separate from your main home.
Guest Accommodations
Provide comfortable, private space for visiting family and friends.
