Garden City Infill Development Guide

Garden City Code Title 8 Chapter 2 Article B establishes base zoning districts with permitted and conditional uses defined in Table 8-2B-1. Single-family detached dwellings are permitted in R-1, R-2, R-3, and R-M districts. Duplexes and townhomes are permitted in R-2, R-3, and R-M. Multifamily structures are permitted in R-3 and R-M districts subject to density and dimensional standards.

Investor implication: Infill developers must confirm base district allowances before acquisition. R-M (medium-density residential) offers the widest range of housing types without conditional use permits, reducing entitlement risk.

Ordinance 1050-24 added the R-M (Medium-Density Residential) zoning district to Garden City Code Title 8, effective August 19, 2024. The R-M district permits single-family, duplex, townhome, and small multifamily uses by right, with density and dimensional standards calibrated for infill development.

Investor implication: R-M is the newest tool for infill operators. Properties rezoned to R-M since August 2024 carry lower entitlement risk than R-3 conditional use paths. Confirm parcel zoning via city GIS before underwriting.

Ordinance 1056-25, effective June 2025, amended Garden City's Planned Unit Development (PUD) provisions to allow flexibility in lot size, setbacks, and density in exchange for enhanced design standards and public amenity contributions. PUD approval is a discretionary process requiring Planning & Zoning Commission and City Council approval.

Investor implication: PUD is a tool for higher-density infill projects (10+ units) where base zoning is restrictive. Expect 90–120 day entitlement timelines and negotiated public benefit requirements (e.g., streetscape improvements, open space dedications).

Garden City's Live-Work-Create overlay district, established in the Chinden Boulevard corridor, permits mixed-use development with reduced parking minimums for live-work units and artist studios. Specific overlay provisions are codified in Garden City Code Title 8 Chapter 3 Overlay Districts.

Investor implication: Live-work infill projects in the overlay district benefit from parking reductions (as low as 0.5 spaces per unit for live-work studios). Confirm overlay boundaries via city zoning map before acquisition.

Idaho Senate Bill 1352, effective July 1, 2026, requires cities with populations over 10,000 to allow residential development at a minimum density of 12 units per acre on tracts of 4 acres or more. Qualifying starter-home subdivisions may use lots as small as 1,400 square feet, and local setback and lot-width requirements do not apply.

Investor implication: Garden City must allow 12 du/ac on tracts ≥4 acres starting July 1, 2026. Infill developers can override local dimensional standards on qualifying parcels. Confirm tract size and starter-home eligibility before underwriting.

Idaho Senate Bill 1354, effective July 1, 2026, requires cities with populations over 10,000 to allow at least one accessory dwelling unit (ADU) per residential lot. Cities may not impose owner-occupancy requirements or blanket square-footage bans. Existing HOA restrictions remain enforceable, but HOAs cannot add new ADU restrictions without written consent of all members.

Investor implication: SB 1354 does not directly govern new construction, but it creates a floor for ADU allowances that Garden City cannot restrict below. Infill projects with ADU components (e.g., detached ADU + primary dwelling) are protected from future local restrictions.
