How is Nampa zoned?
Nampa regulates land through 30 zoning districts, and the residential codes state lot size: RS4, RS6, RS7, RS8.5, RS18 and RS22. RS6 is the largest district in the city at roughly 8,142 acres, more than four times the next residential district.
The distinctive district is Enclave at roughly 2,766 acres, the third largest classification. An enclave designation covers unincorporated pockets surrounded by the city, and at that scale it is a genuine feature of Nampa's geography rather than a technicality. A site in an enclave sits inside the city's boundary but is not governed by a conventional city district.
The Gateway Business districts, numbered 1 and 2 and together covering roughly 877 acres, are a corridor-specific commercial framework rather than a generic business category.
Two institutional districts cover single anchors: University at roughly 192 acres and Healthcare at about 107. Zoning each separately makes their footprints explicit.
Light Industrial is the second largest district at roughly 3,169 acres, with heavy industrial at about 640 and an industrial park district at roughly 528. Community Business covers roughly 1,943 acres. A two family duplex district covers about 1,116 acres, giving real middle-density capacity, and two multiple family districts add roughly 966 more. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
