South Portland regulates land through 47 zoning districts, and the residential districts are lettered rather than named: A, AA, G and further variants. Residential District A is the largest in the city at roughly 2,236 acres. Because the letters carry no descriptive information, the district code here has to be looked up rather than read.
Several districts are named for specific places, which is the city's distinguishing feature. The Shipyard District covers roughly 100 acres, Mill Creek Core about 52, Spring Point roughly 40, West End Residential about 134, and a Western Avenue Commercial Corridor roughly 65. Naming five separate places in a roster of this size shows a city that regulates by location as much as by category.
The Shipyard District in particular is a working classification rather than a heritage one, sitting alongside light industrial at roughly 832 acres and a nonresidential industrial district at about 744.
The commercial ladder is graduated: commercial at roughly 450 acres, central and regional commercial at about 390, suburban commercial at roughly 310, general commercial at about 184, and a transitional version of the central and regional district at roughly 56.
A conditional residential and limited commercial use district covers roughly 68 acres, and a numbered facility district about 85. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
