ADU rules in Keller, TX — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Texas has no statewide ADU mandate, and Keller zoning does not broadly permit ADUs in single-family districts. Guest quarters without kitchens may be allowed as accessory structures, but rental units need PD zoning.
Texas does not have a statewide accessory dwelling unit mandate comparable to California SB 9 and SB 10 or Oregon HB 2001. ADU authority rests entirely with each city, and Keller has not adopted a broad by-right ADU ordinance for single-family residential districts. Under Keller zoning, single-family residential districts generally allow one principal dwelling per lot. Accessory structures such as detached garages, pool houses, workshops, and guest quarters are permitted subject to size limits, setback requirements, and design standards, but these accessory structures typically cannot contain a full second kitchen, separate utility metering, or a separate street address that would convert them into independent dwelling units. A freestanding guest house with a wet bar, bedroom, and bathroom is often allowed as accessory use, but the moment it includes a full cooking facility or is rented as a separate unit it crosses into ADU territory that Keller zoning does not recognize in most single-family districts. Families exploring ADU-style arrangements for aging parents or adult children sometimes pursue a planned development rezoning or a variance, and a handful of mixed-use and higher-density overlay districts may allow them by right. Short-term rental of any accessory unit is separately regulated under the Keller short-term rental ordinance and zoning. HOA covenants in most Keller subdivisions prohibit separate rental dwellings entirely.
