Summary
In Buena Park, exterior air conditioning equipment cannot exceed a 60 dBA noise rating and must also meet the city's separate Chapter 8.28 noise standards. The rule, found in the zoning code's environmental-effects chapter, exempts only self-contained window-mounted air conditioners installed in single-family dwellings.
In addition to the requirements of Title 8, the following noise standards shall be met where applicable: ... B. Air Conditioning Equipment. Exterior air conditioning equipment, other than self-contained window-mounted units in single-family dwellings, shall have a decibel rating of no more than 60dBA and shall comply with the City's noise standards pursuant to Chapter 8.28.
Full Breakdown
344 (Development Standards, Environmental Effects), sets noise standards that apply on top of the citywide noise rules in Title 8. 28. The same section's subsection A sets a companion acoustical-design standard for new residential development: interior spaces in dwellings and group quarters must be designed to keep the community noise equivalent level (CNEL) at or below 45 decibels, and outdoor private or common open areas at or below 65 decibels CNEL, unless it is not reasonably possible, in which case the project must still achieve the lowest noise level reasonably possible within at least 100 square feet of open area per unit.
Both standards were adopted by Ordinance No. 1754, effective June 24, 2025. 040. 28's separate noise limits, is out of compliance with the zoning code regardless of whether a neighbor files a complaint, because the standard is a development requirement, not a complaint-only nuisance rule.
Violations & Fines
A violation of Title 19, including the Section 19.344.010(B) air conditioning noise limit, is a misdemeanor under Section 19.148.010 unless the code specifically labels it an infraction, punishable by a fine of up to $1,000, up to six months in jail, or both. Each day the violation continues is a separate offense. The City may also pursue civil nuisance abatement under Section 19.148.030, including a restraining order or injunction, and recover attorneys' fees if it elects to seek them at the start of the action.
