Generator Permit Requirements in Show Low, AZ
The City of Show Low is an incorporated city (pop. 11,732, 2020) in Navajo County and runs its own Building Safety Department at City Hall, 180 N. 9th St. Permits line is 928-532-4042, administration 928-532-4050, and the 24-hour inspection line is 928-532-4055. ZIP 85901 is a large rural ZIP (about 260 sq mi) where the City of Show Low covers only roughly 15.78 percent; the balance is unincorporated Navajo County and CDPs (Linden, White Mountain Lake, Wagon Wheel, Lake of the Woods, etc.) permitted by Navajo County Planning and Development Services (1100 E. Thornton Rd., Show Low), so addresses must be checked against city limits to pick the correct AHJ.
