In Dallas, Texas, accessory dwelling units (ADUs) on single-family lots are regulated through local zoning and building permit processes. This guide explains who enforces ADU rules, how to apply for permits, typical compliance checks, and common issues to avoid. It summarizes official application pathways and enforcement contacts so homeowners and contractors can plan a compliant ADU project in Dallas.

Overview of the Permit Process

Most ADU projects require review under the city zoning rules and a building permit from the Sustainable Development and Construction department; local development standards may limit size, placement, parking, and occupancy.

Applications & Forms

How the Review Works

Plan reviewers check zoning compliance, building code compliance, electrical, plumbing, mechanical systems, and required inspections during construction. Typical milestones include permit intake, plan review, correction responses, permit issuance, required inspections, and final approval.

  • Plan review: expect at least one plan review cycle and possible correction requests.
  • Inspections: foundation, framing, mechanical/electrical/plumbing, and final inspections are typical.
  • Fees: applicable permit fees are listed in the city fee schedule or the permit portal; specific ADU fees are not specified on the cited guidance page.
Keep copies of all approved plans and inspection reports on-site during construction.
