Kuna is southwest Ada County. Lower basis than Meridian, faster growth than Eagle, and the most active annexation conversation in Ada County. Our investor network has focused here for three years on annexation-and-build plays.
Flips
Flip ARV range
$380K–$480K
Typical
Kuna flip product is thinner than Meridian's but increasing with turnover. Rehab budgets pencil tighter than Meridian.
SFH Rentals
Kuna SFH rentals run at Meridian's basis with slightly softer rent. Tenant quality is stable and vacancy is competitive.
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's displayed code is current through Ordinance 2025-37, while multiple 2026 Title 5 ordinances postdate it. Renew Atlas does not state an exact current ADU standard until the full sequence is reconciled in enactment order.
The public zoning and future-land-use map also predates the 2026 actions. Use the map only for screening and obtain a current city record for a parcel conclusion.
Annexation & Development Land
Annexation window basis
12-to-24-month horizons typically clear at 50–65% of post-annexation comparable.
Kuna's annexation pipeline is the most active in Ada County in percentage-of-city-limits terms. We've represented acquisitions in the 12-to-24-month-to-annexation window where basis clears at 50–65% of post-annexation comparable.

Renew take
Kuna's growth is annexation-driven. The 2023 FLUM expansion is what's pulling the curve up. The land thesis here is timing: catch parcels in the 12-24 month pre-annexation window where basis runs 50-65% of post-annexation comparable.
Kuna's annexation pipeline: track the City Council pre-annexation queue; the FLUM gates the 2027-28 land repricing.

Renew take
Kuna sits in the entry-tier Ada County band, the lowest-basis flip and rental product in the county. New-build supply pulls the median up but the resale 1990s-stock cohort is the investor target.
New-build absorption: when D.R. Horton/Lennar inventory days cross 90, resale comps flatten and the flip math compresses.

Flips

Neighborhoods
4 Kuna neighborhoods. Each with its own read.
Primary and secondary investment neighborhoods with stat cards, Renew takes, risks, and ordinance-level code references.
Old Town Kuna
Historic core south of Avalon Street on the original Avenue B-G grid. Lot-split-viable parcels, alley-accessed lots, and adaptive-reuse opportunities concentrate here. Primary infill target — Ord. 2026-05A (April 7, 2026) removed owner-occupancy on ADUs and waived parking within 1,500 ft of transit. Lot geometry diligence (setbacks, alley access, utility stubs) is the underwriting work.
Neighborhood brief →Production-builder · family rentalsNorth Kuna
Newer production-builder subdivisions north of Deer Flat Road and along King Road. Family-rental demand backed by the Kuna School District and Meridian-commuter spillover. 2025 Future Land Use Map update added Medium Density Residential and Mixed-Use designations across the northeast and northwest growth corridors, expanding the entitlement envelope.
Neighborhood brief →Larger lots · ag-to-residentialSouth Kuna
Bordering the Snake River Birds of Prey National Conservation Area. Larger lots, agricultural-to-residential land entitlement activity along Swan Falls Road and Kuna-Mora Road. Water rights and irrigation district standing (Boise-Kuna Irrigation, Nampa-Meridian) are the dominant diligence items.
