Buildable Infill
Kuna's buildable infill is the play. Mid-block corner lots, alley-accessed parcels, and lots adjacent to utility stubs are where our investor pipeline concentrates. Entitlement clocks are faster than Meridian's.
Lot Splits, ADUs & Duplexes
Kuna adopted Ordinance 2026-05A on April 7, 2026, removing the owner-occupancy requirement and waiving parking within 1,500 feet of a transit stop. Maximum ADU size: 900 square feet or 50% of primary.
The city's updated Future Land Use Map (March 2025) added Medium Density Residential and Mixed-Use designations in northeast and northwest growth corridors, expanding the infill envelope considerably. We track lot geometry against setbacks to pre-qualify viable parcels before underwriting.
