Basement Finishing Permit Requirements in Litchfield Park, AZ
ZIP 85340 carries the postal name Litchfield Park but the incorporated City of Litchfield Park is tiny (3.3 sq mi, ~6,847 pop), only about 20 percent of the ZIP's ~33,778 residents. The remainder is large unincorporated Maricopa County county islands (Planning & Development is the AHJ there) plus slivers of Goodyear and Buckeye, with the city's own FAQ confirming most 85340 addresses outside city limits get services from Maricopa County. This is a genuine multi-AHJ ZIP with no single dominant municipality, so the recommendation is to LEAVE IT UNMAPPED (accuracy over coverage); the best-guess primary AHJ recorded here is unincorporated Maricopa County. Both the City of Litchfield Park and Maricopa County have adopted the 2018 IRC.
