Full Breakdown
Under Town of Babylon Code §§ 213-65, 213-68 and 213-69, an A Residence District lot needs a front yard of at least 40 feet (extendable to 60 feet under a block-face averaging rule), two side yards totaling at least 35 feet with neither under 15 feet, and a rear yard of at least 40 feet. Lots held in single and separate ownership since July 25, 1954 get reduced minimums, side yards down to 28 feet total (10 feet least) and a 25-foot rear yard, but that exception applies only to those specific legacy lots, not to development generally.
Violations & Fines
Building within the required front, side or rear yard without a variance is a zoning violation under § 1-15: a $250 to $2,500 fine, with each day treated as a separate offense.
