ADU Rules

Arlington allows accessory dwelling units in limited residential zoning districts subject to Unified Development Code standards covering size, owner-occupancy, setbacks, and parking. Unlike California or Oregon, Texas has no statewide ADU mandate, so Arlington's local zoning controls whether, where, and how an ADU can be built.

ADU Permits

Arlington allows accessory dwelling units only in limited residential districts under the Arlington Unified Development Code (UDC) Article 4. Detached ADUs (called 'guest quarters' or 'accessory living quarters') typically require a Specific Use Permit (SUP) reviewed by Planning and Zoning Commission and approved by City Council. Building permits issue only after the SUP is granted. Texas has not preempted local discretionary review.
