Overview
Worth knowing
- R-3 'Older Neighborhood' designation: District specifically targets established residential areas with potentially narrower lots and reduced setbacks
- Recent UDC adoption: Unified Development Code (Ordinance 59-25) effective December 1, 2025 modernizes zoning structure; pre-UDC districts R-1/R-2/R-3 superseded by new residential district types
- Three-tiered residential strategy: R-1 (standard single-family), R-2 (alternate single-family), R-3 (historic/older neighborhoods) preserves distinct neighborhood character types
