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

Glendale's mechanical-equipment noise rule sits in the subdivision code rather than the general noise ordinance. 040 targets vibration: any permanent mechanical equipment, expressly including fixed and built-in domestic appliances, that the building official determines is a source of vibration or noise must be shock-mounted, isolated from the floor and ceiling, or otherwise installed in a manner the building official approves to cut down on the noise and vibration reaching neighboring units. That same section's subsection C separately requires drip pans under clothes washers, dishwashers and water heaters, and individually metered utilities for each unit.

The rule does not stop at brand-new condominiums. 040 into every conversion project that received its building permit after June 9, 1994, exempting only the sanitary sewer fee from that cross-reference, so a converted apartment building's air conditioning and heating equipment faces the identical shock-mounting and isolation standard as a ground-up condo project. Because the building official makes the vibration-source determination and approves the installation method case by case, the standard functions as a discretionary condition of subdivision or conversion approval rather than a fixed decibel limit, layered on top of, not a substitute for, the citywide fixed-noise-source rules elsewhere in the Municipal Code.
