Inglewood, CA Noise from Specific Sources: HVAC & Mechanical Noise (2026)

Section 5-39 of the Inglewood Municipal Code, part of the City's 1988 noise ordinance (Ord. 88-29), makes it unlawful to 'operate, cause to operate or permit the operation of any machinery, equipment, device, pump, fan, compressor, air-conditioning apparatus, or similar mechanical device' if the resulting noise at the property line exceeds the ambient noise base level by five dB(A). The ambient noise base level is the pre-existing background sound level established for the zone under a separate section of Article 2, and Code Enforcement or the Inglewood Police Department measures a complaint against that baseline rather than a single fixed decibel number, so the same air-conditioning unit can be legal on a busy commercial block and a violation on a quiet residential street.

, Section 5-39 carries no time-of-day exemption for HVAC or mechanical equipment. Section 5-41 separately regulates construction noise and requires a permit from the Permits and Licenses Committee for late-night work, but that permit process does not extend to routine air-conditioning or refrigeration equipment covered by Section 5-39. Emergency repair and utility restoration work is exempt from the neighboring construction-noise section under Section 5-42, but that carve-out likewise does not reach ordinary HVAC operation. Rooftop condensers, pool pumps and commercial refrigeration compressors placed near a residential property line are the most common subjects of complaints under this section.
