Maintain Building Systems at Appropriate Noise Levels
Periodically check that any noise-producing building systems, such as air circulation devices, don't exceed unreasonable noise levels. N.Y.C. Administrative Code Section 27-218 provides that no person shall cause or permit “unreasonable noise,” which is defined in the Building Code as any excessive or unusually loud sound that disturbs the peace or comfort of a reasonable person of normal sensitivities, or injures or endangers health or damages property. Unreasonable noise includes any noise over 10 decibels between 7 a.m. and 10 p.m.
