Building permits in Dallas County (Unincorporated)

Dallas County (Unincorporated) does not issue residential building permits. In unincorporated Dallas County the Department of Unincorporated Area Services requires a Notice of Residential Construction for new residential construction, additions, and major structural renovations, rather than a conventional city building permit. Site work such as grading, fill, excavation, drainage and any development in a floodplain, including fences, needs a Development Permit or Floodplain Development Application. Reach DUAS at 214-653-6565 or Development@DallasCounty.org. If your property is inside a city, contact that city instead.

That does not make the work unregulated. The construction standard still applies, trade licensing still applies, and separate approvals such as on-site sewage, floodplain development, and driveway access are handled by other offices. Below are the contact details for the office to ask, plus guides for the projects homeowners ask about most.

Texas does not have a single statewide building code or a statewide permitting agency; instead, state law adopts the International Residential Code as the municipal residential building code and municipalities enforce it locally, adding their own amendments. Permits are issued at the local level, and there is no statewide dollar-value threshold that exempts a project from needing a permit, so whether your work needs a permit in Dallas County (Unincorporated) depends entirely on the local jurisdiction. Many Texas counties also have limited authority to require building permits for one- and two-family homes in unincorporated areas, so if you are outside city limits the rules can differ sharply. Always confirm requirements directly with the building department that covers Dallas County (Unincorporated) before you begin.

Who issues building permits in Dallas County (Unincorporated)?
Nobody does. Dallas County (Unincorporated) does not run a residential building permit program, which is why this page lists Department of Unincorporated Area Services (DUAS) as the office to contact rather than as a permit issuer. Your mailing city is not always the authority over your property, so confirm which jurisdiction you are actually in before assuming this applies to you.
What still applies in Dallas County (Unincorporated) if there is no building permit?
The construction standard does. Work must still meet the International Residential Code, which Texas municipalities adopt and enforce locally under Chapter 214 of the Texas Local Government Code, and trade licensing rules apply regardless of whether a permit is issued. Separate approvals such as on-site sewage, floodplain development, and driveway access to a public road are handled by other offices and are unaffected. Ask Department of Unincorporated Area Services (DUAS) which of those reach your property before you start.
