Chesapeake, VA Noise from Specific Sources: HVAC & Mechanical Noise (2026)

Chesapeake's general noise standards, set out in Sec. 26-130's Table 1, cap sound at 55 dBA measured on residential property and 60 dBA on commercial or agricultural property, with octave-band limits reduced by 5 dB for tonal or impulsive noise. Those numeric limits, along with the nighttime rule in Sec. , would ordinarily catch a noisy air-conditioning condenser or heat pump running near a property line. Division 4 of the noise article removes that possibility for HVAC equipment specifically: Sec. 26-141(15) exempts 'noises generated by the operation of heating, ventilation and air conditioning units (HVAC units) attached to a building or structure' with no hour restriction, no decibel ceiling, and no distinction between residential, commercial or agricultural zoning.

The exemption sits alongside the article's other Division 4 carve-outs for emergency generators, agricultural equipment, church bells and city waste collection, reflecting the same legislative judgment that certain building-integral, non-discretionary noise sources shouldn't be litigated case by case. A resident who wants relief from a neighbor's especially loud unit has no noise-ordinance remedy under this article; any recourse would have to come through a different code section, such as a nuisance or property-maintenance provision, rather than Sec. 26-124 through 26-131's noise enforcement scheme.
