Full Breakdown
Hesperia's development code sets maximum sound levels measured at the property line of the receiving land use, not the source. Residential zones (A-1, A-2, R-1, R-3, RR) are capped at 55 dB(A) overnight (10 p.m.-7 a.m.) and 60 dB(A) during the day; commercial zones cap at 65 dB(A) and industrial zones at 70 dB(A), both around the clock. A violation occurs when a source exceeds the standard for more than 30 minutes in any hour, with shorter allowed spikes at higher decibel add-ons. The building official serves as noise control officer, and daytime construction (7 a.m.-7 p.m. weekdays) is exempt.
Violations & Fines
Enforced by the building official as noise control officer; prosecuted under HMC § 1.12.030 as a misdemeanor (up to $1,000 fine, 6 months) or reduced infraction ($100-$500).
