Full Breakdown
3, sets yard setback minimums that fall as density rises. In the RL-1 and RL-2 low-density single-family districts, the minimum front setback is 30 feet or the average front setback of abutting structures, whichever governs, but the Ordinance caps the requirement so that in no case is a setback greater than 45 feet required. RL-3 reduces the front setback to 25 feet, with a maximum of 35 feet. Interior side setbacks in the RL districts are 8 feet in RL-1 and RL-2 and 7 feet in RL-3; corner side setbacks run 15 feet in RL-1, 12 feet in RL-2, and 10 feet in RL-3, though the Ordinance allows the corner side setback to be reduced for residential uses to preserve a minimum buildable width, never below 7 to 8 feet.
Rear setbacks are a flat 35 feet in all three RL districts. The medium-density RM-1 and RM-2 districts shrink the front setback to 5 feet or the average of abutting structures, whichever is less, with a 5-foot interior side setback and a 25-foot rear setback. The high-density RH-1 and RH-2 districts scale setbacks to building height: structures 35 feet tall or less need only a 5-foot front setback (or the abutting average, whichever is less) and a 25-foot rear setback, while structures taller than 35 feet require a 20-foot front setback, a 12-foot corner side setback, and a 35-foot rear setback.
Multi-family interior side setbacks in RH-1/RH-2 increase with height: 12 feet or 15% of lot width for structures up to 35 feet, plus one additional foot of setback for every 2 feet of height above 35 feet.
Violations & Fines
A building erected without meeting the applicable yard setback is a violation the Zoning Officer enforces under Article 17. The Officer issues written notice by certified mail giving the owner 15 days to respond with a remedy; if the violation creates a hazardous condition, correction can be ordered within 24 to 48 hours under § 315-17.4. Unresolved violations void the certificate of occupancy and trigger a Municipal Court summons.
