Full Breakdown
Chapter 30, Sec. A defines a setback as the line, equidistant from the lot line, that establishes the closest point at which a principal building may be erected. The Sec. 3 table sets the actual minimums for the three Single Residence districts. For lots created on or after December 7, 1953: SR1 requires a 40-foot front, 20-foot side and 25-foot rear setback; SR2 requires 30 feet front, 15 feet side and 15 feet rear; SR3 requires 30 feet front, 10 feet side and 15 feet rear.
5 feet in SR2 and SR3, and the same 25/15/15-foot rear setbacks. Sec. B lets the front setback average with the setbacks of the nearest buildings on either side rather than meeting the district minimum outright, but in no case may any part of a building in a residence district come nearer than 10 feet to the street line. Sec. D allows specific features to project into the required setback without triggering a violation: steps, landings and bulkheads; heat pump compressors kept within 5 feet of the exterior wall; up to 8 inches of exterior insulation; doorway vestibules up to 4 feet deep; and roof overhangs and gutters up to 3 feet.
Sec. G lets the City Traffic Engineer order removal, at the owner's expense, of any setback obstruction that creates a traffic hazard, following a City Council public hearing. The Sec. 1 table was most recently amended by Ordinance No. C-67 on October 20, 2025.
Violations & Fines
Building or expanding a structure inside the required setback without City Council relief violates Chapter 30. Sec. 7.9.2 fines a violator up to $300 for each day the encroachment continues, and the Commissioner of Inspectional Services will not issue a building permit for plans that violate the Sec. 3.1.3 setback minimums. The Commissioner investigates written complaints, orders violations to cease, and enforcement decisions are appealable to the Zoning Board of Appeals within 30 days.
