Where this pathway usually breaks. And where it actually works.
Kuna's district structure allows density scaling from R-2 (single-family) through R-8 (multifamily), with mixed-use overlays in Old Town Kuna and along major corridors. Infill operators should target R-4 and R-6 districts for duplex/triplex/fourplex projects where lot assemblage is feasible.
Lot size minimums and density caps determine feasibility for lot splits, duplexes, and small multifamily projects. Verify district-specific standards before acquisition to confirm unit count and parking requirements align with pro forma.
Setback and height limits constrain buildable envelope on infill lots, particularly in R-2 and R-4 districts. Alley access may allow reduced rear setbacks; verify with Kuna Planning & Zoning before site plan submission.
Parking requirements can consume significant lot area on small infill parcels. Confirm whether shared parking agreements or on-street parking credits are allowed in Old Town Kuna or mixed-use zones to maximize unit count.
SB 1352 overrides local density caps for qualifying projects, enabling higher-density infill on larger assemblages (4+ acres). Kuna must comply by July 1, 2026. Operators should target parcels at or above 4 acres for maximum unit count under this state mandate.
SB 1354 guarantees ADU rights statewide, removing local owner-occupancy barriers. Kuna must align its ADU ordinance by July 1, 2026. Investors can plan for ADU income on infill acquisitions, but verify HOA covenants on a per-parcel basis.
Mixed-use infill in Old Town Kuna and along major corridors may allow higher density and reduced parking if ground-floor commercial is included. Confirm whether residential-only projects are permitted in mixed-use zones or if commercial component is mandatory.
