Code references active as of publication. Verify current standards at the official source before any development decision.
R-1 Estate Residential District — minimum lot size 1 acre, single-family detached dwellings, agricultural uses permitted, maximum density 1 unit per acre.
Investor implication: R-1 parcels require large lot assemblies for subdivision; best suited for estate-home flips or long-hold land banking in Area of Impact.
R-2 Low Density Residential District — minimum lot size 7,000 square feet, single-family detached dwellings, accessory dwelling units permitted per KCC 5-1-6 and KCC 5-3-4, maximum density approximately 6 units per acre.
Investor implication: R-2 is the primary infill district for ADU plays and lot-split opportunities in Old Town Kuna; verify ADU standards at KCC 5-1-6 before underwriting.
R-4 Low-Medium Density Residential District — minimum lot size, permitted uses, and density cap pending verification at https://library.municode.com/id/kuna/codes/development_regulations_code/title_5/chapter_3 — typically allows single-family attached, townhomes, and small multifamily.
Investor implication: R-4 supports attached-product infill; confirm dimensional standards at library.municode.com/id/kuna before site plan.
R-6 Medium Density Residential District — minimum lot size, permitted uses, and density cap pending verification at https://library.municode.com/id/kuna/codes/development_regulations_code/title_5/chapter_3 — typically allows multifamily up to 12-15 units per acre.
Investor implication: R-6 is the primary multifamily district; verify parking ratios and setback requirements before acquisition.
R-8 High Density Residential District — minimum lot size, permitted uses, and density cap pending verification at https://library.municode.com/id/kuna/codes/development_regulations_code/title_5/chapter_3 — typically allows multifamily up to 20+ units per acre.
Investor implication: R-8 parcels are rare in Kuna; most high-density development occurs through PUD overlay rather than base R-8 zoning.
C-1 Neighborhood Commercial District — small-scale retail, office, service uses serving adjacent residential neighborhoods, residential uses permitted on upper floors or as part of mixed-use development.
Investor implication: C-1 along Avenue B and Avenue G in Old Town Kuna supports mixed-use infill; verify parking requirements and FAR limits before underwriting.
C-2 General Commercial District — broader range of retail, office, service, and entertainment uses, higher intensity than C-1, residential uses permitted as part of mixed-use development.
Investor implication: C-2 parcels along major corridors (e.g., Meridian Road) support larger commercial or mixed-use projects; confirm traffic impact study requirements.
LI Light Industrial District — warehousing, light manufacturing, distribution, office uses, limited retail, residential uses generally not permitted.
Investor implication: LI parcels near railroad corridor support warehouse/distribution plays; verify truck access and loading dock requirements.
A Agricultural District — agricultural uses, single-family dwellings on large lots (typically 1+ acres), limited commercial agricultural uses permitted.
Investor implication: A-zoned parcels in Area of Impact are long-horizon land plays; confirm annexation timeline and future land use designation before acquisition.
PUD Planned Unit Development Overlay — allows flexible site design, mixed uses, density bonuses in exchange for open space, amenities, or affordable housing; requires master plan approval by Planning & Zoning Commission and City Council.
Investor implication: PUD overlay is the primary tool for higher-density residential or mixed-use projects; expect 6-12 month entitlement timeline and public hearing process.
Floodplain Overlay — parcels within FEMA-designated 100-year floodplain (primarily along Tenmile Creek) subject to additional development restrictions, elevation requirements, and floodplain development permit.
Investor implication: Floodplain parcels require elevation certificates and may face higher insurance costs; verify FEMA map status at msc.fema.gov before underwriting.
Setback requirements vary by district; illustrative ranges pending verification: R-1 typically 25-foot front, 10-foot side, 25-foot rear; R-2 typically 20-foot front, 5-foot side, 20-foot rear; commercial districts typically 15-foot front, 0-foot side (if shared wall), 10-foot rear. Exact setbacks by district must be verified at https://library.municode.com/id/kuna/codes/development_regulations_code/title_5/chapter_3 before any development decision.
Investor implication: Setback encroachments require variance; confirm buildable area before site plan to avoid costly redesigns.
Maximum building height; illustrative ranges pending verification: residential districts typically 35 feet (2.5 stories), commercial districts typically 45 feet, industrial districts typically 50 feet. Exact height limits by district must be verified at https://library.municode.com/id/kuna/codes/development_regulations_code/title_5/chapter_3 before any development decision.
Investor implication: Height limits constrain multifamily and mixed-use density; PUD overlay may allow height bonuses in exchange for public benefits.
Parking requirements; illustrative ranges pending verification: single-family 2 spaces per unit, multifamily 1.5-2 spaces per unit depending on bedroom count, commercial 1 space per 300-400 square feet depending on use. Exact parking ratios by use type must be verified at https://library.municode.com/id/kuna/codes/development_regulations_code/title_5 before any development decision.
Investor implication: Parking requirements drive site layout and cost; confirm ratios before land acquisition to avoid undersized parcels.
Kuna Ordinance 2026-05A (effective April 7, 2026) amended ADU regulations: removed owner-occupancy requirement, increased maximum ADU size to 900 square feet or 50% of primary dwelling (whichever is less), waived parking requirements within 1,500 feet of transit.
Investor implication: ADU plays in R-2 Old Town Kuna are now viable without owner-occupancy; verify transit proximity for parking waiver eligibility.
