Full Breakdown
Chapter 50's Article XIII dimensional-standards tables (Sec. 50-13-2 through 50-13-7) set minimum yard setbacks for every residential zoning district. In R1, a single-family dwelling needs a 20-foot front setback, side setbacks of at least 4 feet each with 14 feet combined, and a 30-foot rear setback, plus a 35% maximum lot coverage cap. Non-residential uses like schools and religious institutions instead use a length-and-height formula (Formula B) to compute the side setback. R2 through R6 districts carry their own, generally smaller, tables in the same article. The Buildings, Safety Engineering, and Environmental Department (BSEED) reviews building permits for compliance before construction.
Violations & Fines
BSEED can issue a blight violation for a structure that projects or encroaches into a required front, side, or rear setback: $250 for a first offense, $500 for a second, and $1,000 for third and subsequent offenses under Sec. 50-5-30.
