Full Breakdown
Rather than one setback table for every house, the Unified Development Code's Section 405.020 assigns front, side, corner-side and rear minimums to each residential building type, scaled to that type's lot size. Estate-lot detached houses, the largest single-family option, require a 50-foot front setback, 25 feet on the side and rear, and 50 feet on a corner side. Neighborhood-lot detached houses, a mid-size single-family type, drop to 25 feet front, 8 feet side, 25 feet corner side and 15 feet rear. Duplexes on a standard lot require 50 feet front when the lot fronts a collector street (20 feet on any other street), 10 feet side (0 feet where a party wall is used, with 20 feet minimum separation between buildings), 20 feet corner side, and 20 feet rear (4 feet for an alley-loaded detached garage).
Front-loaded and side-loaded duplex garages must additionally sit back at least 50 feet from a collector street and 20 feet from any other street. Community Development measures these distances from the building's exterior wall to the lot line during site plan and building permit review, and a house that cannot meet its building type's setback must either be redesigned or apply for a variance under Section 403.060.
Violations & Fines
Building closer to a property line than the applicable building type's setback is a zoning violation caught by Community Development during building permit plan review, or by code enforcement after construction; the City can require the encroaching wall, deck or garage be relocated or removed, and any occupancy permit can be withheld until the structure complies or a variance is granted under Section 403.060.
