ADU rules in Peoria, AZ — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Peoria allows Accessory Dwelling Units on single-family lots following Arizona HB 2720. ADUs must be smaller than the primary dwelling, meet setback requirements, and comply with building codes.
Arizona HB 2720 requires cities with populations over 75,000, including Peoria, to allow ADUs on any lot where a single-family dwelling is permitted. ADUs must be self-contained units with sleeping and sanitation facilities and may include a kitchen. They must be smaller in square footage than the primary dwelling. Detached ADUs must meet zoning setback requirements. ADUs require building permits and must comply with all applicable building codes. The city may establish design standards for compatibility with the primary residence.
Unpermitted ADUs must be brought into compliance. Construction without permits results in code violations and required permitting.
