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

Chapter 285 of the Troy City Code, adopted by the Troy City Council in Rensselaer County, New York, puts the yard minimums inside each residential district section under the heading Lot characteristics. In the R-1 Single-Family Residential Detached district (§ 285-52) the minimums are 25 feet in front, 30 feet in the rear, and 10 feet on each side, or 20 feet on one side if the lot uses a zero lot line design. The R-2 Two-Family district (§ 285-53) drops the front setback to 20 feet, keeps the rear at 30 feet, and sets sides at five feet each or 10 feet on one side with a zero lot line design.

The R-3 Multiple-Family Medium-Density district (§ 285-54) requires 15 feet in front, 20 feet in the rear, and 10 feet total for the sides. The R-4 Urban Neighborhood district (§ 285-55) requires 10 feet in front, 20 feet in the rear, and 10 feet total of both sides.\n\nThree general rules in § 285-51 control how those numbers work. Under subsection B, no building may be erected or altered to have narrower or smaller rear yards, front yards or side yards than the district specifies. Under subsection C, yard space counted toward one building cannot be counted again for another building.

Under subsection D, no lot, yard or setback can be reduced below the minimum, and a space already under the minimum cannot be reduced further. Subsection E applies area requirements such as setbacks to new construction only, so existing structures with or without a change of use do not have to meet the zone's area requirements, and adding dwelling units to an existing building counts as new construction. Subsection G bars the Director of Code Enforcement from altering, waiving or interpreting the specific requirements of §§ 285-52 through 285-67, so relief from a setback goes through the Zoning Board of Appeals as an area variance.
