Irondequoit, NY Building Setbacks & Zoning: Setback Rules (2026)

Section 235-11 of the Town of Irondequoit zoning chapter sets yard setbacks for the R-R, R-1, R-2 and R-3 Residential Districts.

Front yard. In R-1, R-2 and R-3 the front yard is at least 30 feet, and the front building line cannot vary more than five feet from the front building line of properties immediately adjacent. In R-R the front setback is at least 50 feet and no more than 75 feet. Porches, decks, stoops and protective coverings can project into a compliant front yard only if the platform or covering is less than 60 square feet and less than six feet in depth, and an attached platform must still keep a twenty-foot setback to the front lot line. Structures that miss the front yard minimum are limited to entry platforms and coverings of 20 square feet and four feet in depth. On a corner lot the front yard setback applies to every yard adjacent to a street, and on a through lot the minimum front yard applies on both streets.

Side yard. The principal building must sit a distance equal to 10% of the lot width from the side line, with a minimum of five feet. The requirement is capped at 15 feet in R-1, R-2 and R-3 and at 25 feet in R-R.

Rear yard. Principal structures need a 30 foot rear yard in R-1, R-2 and R-3 and 50 feet in R-R. Decks attached to the house keep a 20 foot setback from the lot line in all four districts.

New lots must meet the printed minimums: for R-1, R-2 and R-3, 80 feet of lot width, 120 feet of depth and 9,600 square feet; for R-R, 150 feet, 300 feet and 45,000 square feet. Detached accessory structures follow § 235-13 instead.
