Do I need a permit for water heater replacement 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.
