ADU rules in Little Elm, TX — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
ADUs are not permitted by-right in residential zones under Chapter 106. A zoning variance or special use permit from the Town Council is required.
Little Elm's zoning ordinance under Chapter 106 does not include provisions for accessory dwelling units, granny flats, or secondary living quarters in single-family residential zoning districts. Texas does not have a statewide ADU mandate, and individual municipalities retain full zoning authority over secondary dwelling approvals. Accessory structures in Little Elm are defined as subordinate to the principal dwelling and limited to uses customarily incidental to the primary residential use such as storage, workshops, or garages. Converting any accessory structure to habitable living space would require meeting all building code requirements for habitable space including egress windows, HVAC, plumbing, and electrical service, as well as obtaining a zoning variance or special use permit. A request for ADU use would go before the Planning and Zoning Commission and Town Council for approval. Properties in planned development districts may have additional restrictions through their development agreements. Residents interested in ADU options should contact the Little Elm Planning Department at 214-975-0472 to discuss feasibility.
