Auburn, AL Building Setbacks & Zoning: Setback Rules (2026)

01 and its Table 5-1 govern conventional single-family subdivisions citywide (outside the Neighborhood Conservation District, which instead uses Table 5-2's per-zone NC-4 through NC-150 schedule). For lots under 20,000 square feet, the table requires a 25-foot street yard, a 6-foot minimum side yard, a 20-foot side-street yard, 15 feet of total side yard, and a 20-foot rear yard, on a 70-foot-wide lot (60 feet for lots under 10,000 square feet). Requirements grow with lot size: 20,000-29,999 square foot lots need a 10-foot side yard and 30-foot rear yard; 30,000-39,999 square foot lots need a 12-foot side yard and 35-foot rear yard; and lots of 40,000 square feet or more need a 15-foot side yard, 25-foot side-street yard, and 40-foot rear yard.

35 on lots under 20,000 square feet. Flag lots follow separate minimum standards under Section 517, and lots on a curve are measured per the City of Auburn Subdivision Regulations, Article IV, Section (E)(2). Certain features may still project into or sit within a required yard: awnings, canopies, roof overhangs, and balconies up to 3 feet; bay windows up to 2 feet; clotheslines; driveways, fences, walls, and hedges (if they violate no other Ordinance provision); and uncovered decks no taller than 30 inches may come within 5 feet of the property line.

Section 503's angle-of-light-exposure setback formula, which scales setback to building height by zoning district, expressly does not apply to conventional subdivisions covered by Table 5-1.
