Chino Hills, CA Noise from Specific Sources: Generator Noise (2026)

070 gives 'Generator' its own line among the accessory features permitted in a residential yard, separate from the 'Mechanical Equipment' row that covers items like pool pumps and compressors. A generator cannot sit in the front yard at all, and it needs at least a five-foot setback from the rear, interior side, and street-side property lines, the same distance the table gives a built-in barbecue, fireplace, or water feature; that is a wider buffer than the three-foot setback the table sets for general mechanical equipment.

020, the citywide exterior sound level chapter that sets numeric decibel limits by receiving zone and time period. Because Chino Hills sits in a wildland-urban interface area and loses power during Public Safety Power Shutoffs, portable and standby generators are common, and this screening-plus-noise combination is the specific local check that applies to them on top of whatever electrical permit the installation needs under Title 15. The rule in Table 10-1(B) applies citywide to residentially zoned properties.
