Local Rules VaryTexas ADU Intelligence
Texas ADU Rules
Texas ADU requirements can vary substantially by municipality, county, zoning district, and property. Homeowners should begin with the rules of the specific jurisdiction where the property is located.
At a Glance
What to know about ADUs in Texas.
These are the major statewide points to understand before drilling into city, county, and property requirements.
01
Rules can vary by city and county
02
Zoning and deed restrictions may affect ADU development
03
Parking, setbacks, size, and use requirements may be local
04
Property-specific research is especially important
Important
Local requirements still matter.
A statewide ADU proposal considered during the 2025 legislative session did not complete passage. Do not assume that one statewide ADU standard applies to every Texas property.

Local Texas guides are coming.
We're building city and county guides to complement this statewide information.
Before Choosing a Plan
Start with the property, not just the floor plan.
The plan works best when it follows the real-world conditions of the building site.
01
Understand the State
Start with the broader Texas ADU framework and the statewide rules that may apply.
02
Research the Locality
Check the city or county rules that may add requirements, limits, or approvals.
03
Verify the Property
Review zoning, setbacks, utilities, septic, access, and other property-specific conditions.
04
Choose the Plan
Use what you learned to narrow down the ADU plans that make sense for the site.

Before You Build
Verify current requirements.
