Summary
Hempstead treats a noisy air-conditioning unit the same as any other mechanical nuisance: § 144-3(N) of the Unreasonable Noise chapter bans operating machinery, equipment, pumps, fans, exhaust fans, attic fans, air-conditioning apparatus or similar mechanical devices in a manner that creates unreasonable noise across a real property boundary, with no set hours or decibel figure.
N. The operation of any machinery, equipment, pump, fan, exhaust fan, attic fan, air-conditioning apparatus or similar mechanical device in such a manner as to create an unreasonable noise across a real property boundary.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: rev 4863878; v67 updated 2026-04-28; through 04-28-2026).
Full Breakdown
' That makes placement and maintenance the practical compliance tools, since the code does not distinguish between a window unit, a central air condenser or a commercial rooftop system; each is an 'air-conditioning apparatus' or 'similar mechanical device' under the plain text. The same subsection reaches other household and commercial equipment side by side with air conditioning, including sump pumps, exhaust fans and general machinery, so a noisy pool pump or rooftop HVAC unit at a business is evaluated under the identical boundary-crossing standard. A resident whose sleep or use of their yard is disrupted by a neighbor's or a business's air-conditioning unit can bring a complaint to Town code enforcement citing § 144-3(N) directly.
Violations & Fines
A violation of § 144-3(N) is punishable under § 144-7 by a fine of up to $250, imprisonment for up to 15 days, or both, for each offense. Because there is no time exemption, a unit found in violation can be cited regardless of when the complaint is made.
