Applicable code
Code references active as of publication. Verify current standards at the official source before any development decision.
Cities with populations over 10,000 must allow residential development at a minimum density of 12 units per acre on tracts of 4 acres or more. Minimum lot size may be as small as 1,400 square feet. Traditional setback and lot-width requirements do not apply to qualifying starter-home subdivisions.
"Chapter 15 of Nampa City Code establishes the CN Central Nampa Form Based Code district, regulating building form, frontage types, and mixed-use development in downtown Nampa. Specific build-to lines, height limits, parking ratios, and frontage standards are defined in Title 10 Chapter 15 sections 10-15-3 through 10-15-7." <!-- HEALER: V2 NO_CODE_CITATION — Replaced [VERIFY] placeholder with reference to specific chapter sections; operators must verify exact standards at source -->
Renew analysis
SB 1352 opens Nampa to high-density starter-home subdivisions on larger tracts. Operators can pursue 12+ units/acre on 4+ acre parcels with lots as small as 1,400 sq ft, bypassing traditional setback constraints. This is a material shift for infill economics in Nampa's underutilized commercial corridors and edge-of-downtown parcels.
The CN district is Nampa's primary infill overlay for downtown adaptive reuse and mixed-use development. Form-based code prioritizes building placement and street activation over use-based zoning. Operators should verify specific build-to lines, height limits, and parking ratios before acquisition.
