Caldwell Zoning Guide

Caldwell establishes residential zoning districts including R-1 (Single-Family Residential), R-2 (Two-Family Residential), R-3 (Multiple-Family Residential), and R-4 (High-Density Residential), each with specific permitted uses, lot size minimums, and density standards.

Investor implication: District classification determines maximum density, permitted uses, and development feasibility. R-1 limits single-family only; R-3/R-4 enable multifamily plays. Verify district boundaries via city GIS before acquisition.

Minimum lot sizes vary by district: R-1 typically requires 6,000–7,000 sq ft; R-2 allows smaller lots for duplexes; R-3/R-4 use density-based standards rather than strict lot minimums.

Investor implication: Lot size drives feasibility for splits, ADUs, and infill. R-1 parcels under 6,000 sq ft may be nonconforming; verify buildability before acquisition. R-3/R-4 density rules enable higher unit counts on smaller footprints.

Standard setbacks in residential districts: front 20–25 feet, side 5–10 feet, rear 20 feet. Specific requirements vary by district and lot configuration.

Investor implication: Setbacks constrain buildable area and ADU placement. Verify exact setbacks per district before site planning. Nonconforming structures may limit expansion or ADU feasibility.

Caldwell applies overlay districts for specific areas including downtown mixed-use zones, urban renewal districts, and buffer zones along major corridors such as Gunfire Road. Overlays modify base zoning with additional standards for landscaping, setbacks, and permitted uses.

Investor implication: Overlay zones add compliance layers that can increase costs or delay approvals. Downtown overlays may enable mixed-use infill; buffer overlays may restrict density. Check overlay status before LOI.

Nonconforming uses and structures existing prior to zoning changes may continue but face restrictions on expansion, modification, or rebuilding after damage. Abandonment for specified periods may terminate nonconforming status.

Investor implication: Nonconforming properties carry redevelopment risk. Expansion or major rehab may trigger full compliance with current code. Verify nonconforming status and rebuild rights before acquisition.
