Summary
Ground-based air-conditioning and heating equipment on new downtown Yonkers buildings can only go in the rear or interior side yard, at least five feet from any lot line, and never in a front or side-front yard. The zoning code also requires that equipment comply with the city's separate Noise Ordinance in Chapter 66.
All ground-based mechanical equipment, including, but not limited to, heating, ventilating, and air-conditioning units (HVAC), must be located only in the rear or interior side yard a minimum of five feet from any lot line. Ground-based mechanical equipment is prohibited within the front or side front yard. Ground-based mechanical equipment must comply with the City's Noise Ordinance.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: rev 4745274; v31 updated 2025-10-28; through 10-28-2025).
Full Breakdown
Section 43-223E, part of the downtown districts' design standards added to the Zoning Chapter in 2011, sets four rules for mechanical equipment on new construction in D-MX, D-IRT, UR-LD, UR-MD and UR-HD. Locating equipment inside the building is preferred and strongly encouraged, and ground-based equipment is discouraged generally, with the code directing that mechanical equipment be contained within buildings or roof-mounted wherever possible. Roof-mounted equipment that is used must be architecturally integrated into the design of the structure rather than left exposed. For any ground-based equipment that remains, § 43-223E(4) is explicit: heating, ventilating and air-conditioning units, along with all other ground-based mechanical equipment, must sit only in the rear yard or an interior side yard, set back a minimum of five feet from any lot line, and are flatly prohibited in the front yard or side front yard.
The same subsection cross-references Chapter 66, the City's Noise Ordinance, requiring ground-based equipment to comply with it as a separate, additional obligation on top of the siting rule.
Violations & Fines
A condenser or heat pump installed in a front or side-front yard, or closer than five feet to a lot line, fails § 43-223E(4) and can hold up building permit sign-off or certificate of occupancy for downtown construction until it is relocated or screened to comply. Equipment that also produces a noise disturbance can separately draw enforcement under Chapter 66, independent of the siting violation.
