Surprise adopted its current Accessory Dwelling Unit standard by Ord. No. 2025-43 (Sec. 1, Exh. A), effective 12-17-24, in LDO Chapter 106, Article XI (Sec. 106-11.1 through Sec. 106-11.7). Confirmed live this session: the adopted local standard matches the HB2720 by-right figures. Per Sec. 106-11.3: on a single-family lot with a primary dwelling, up to 1 attached and 1 detached ADU are a permitted use (up to 1 attached and 2 detached on lots of 1 acre or more if at least one ADU is a restricted-affordable dwelling unit). An ADU's size may not exceed the lesser of 75 percent of the primary home's gross floor area or 1,000 square feet. Per Sec. 106-11.4: the ADU is subject to the same setbacks, lot coverage, and height limits as the primary single-family dwelling, except the rear and side setbacks are reduced to a minimum of 5 feet, no additional parking space or in-lieu fee is required, and the ADU is not required to match the primary home's exterior design. ADUs are not permitted on the same lot as a duplex or other multifamily development, and the standard excludes lots on tribal land or in the vicinity of a military or public airport (A.R.S. Sec. 28-8461, 28-8486). Arizona's statewide ADU law (HB2720, 2024, codified at A.R.S. Sec. 9-461.18) required cities and towns over 75,000 residents to adopt these by-right standards by January 1, 2025; Surprise's 2020 census population (143,148; 2024 estimate approximately 167,564) is well above that threshold, and its Article XI standard was adopted one day before the deadline.
