Frequently asked questions — Dallas County, Texas
Does Dallas have zoning unlike Houston?
Yes. Dallas has a comprehensive zoning code with single-family, multifamily, commercial, and industrial districts. This is a major difference from Houston. Always check the Dallas zoning map before purchasing property or designing a project — the permitted use and development standards depend entirely on the zoning district.
How did Dallas change its ADU rules?
In 2022, Dallas updated its zoning to allow detached ADUs (backyard cottages/garage apartments) in all single-family districts. Previously ADUs were heavily restricted. The change was driven by housing affordability concerns and has significantly increased ADU permit applications in Dallas.
Why do hail storms affect permit timelines in Dallas?
The Dallas-Fort Worth Metroplex is in Tornado Alley and receives significant hail events, often multiple times per year. Large hail events generate thousands of roofing permit applications simultaneously, creating backlogs of 2–4 weeks for roofing permits even though normal processing is 1–3 days.
Is the Dallas County government involved in building permits?
No. Dallas County government (the county commissioners court) does not issue building permits. All permitting in Dallas County is handled by the individual incorporated cities. There is virtually no unincorporated land in Dallas County.
