South Tucson, Arizona has adopted: South Tucson is a separately incorporated city (population roughly 5,000, land area approximately 1 square mile) that is entirely surrounded by, but administratively and legally independent of, the City of Tucson -- it is sometimes called 'The Pueblo within a City.' South Tucson runs its own Planning, Zoning and Development Services Department, which independently reviews building plans and issues its own building, electrical, plumbing, mechanical/HVAC, sign, demolition, and remodel permits; it does NOT contract building-permit administration to the City of Tucson or to Pima County.

Title 9).
