Any rural or residential lot in the unincorporated area of the county may be issued a development permit for the placement of one single-wide or multi-sectional manufactured home built after June 15, 1976. The unit must be on a permanent foundation system, which means either on a slab/stem wall foundation or on a state approved system. Re-roofing, re-siding and structural additions must conform to the Maricopa County Comprehensive Building Code. Manufactured homes are also permitted in a mobile home park.
