Full Breakdown

The noise ordinance's exemption list covers only three sources, and temporary construction, repair, or demolition work is one of them, but only for work performed between 7:00 a.m. and 7:00 p.m., excluding Sundays and federal holidays. Work outside that window, or occurring on a Sunday or holiday, loses the exemption and must instead meet the same decibel limits and cumulative-time thresholds set for the property's zone under Section 16.20.125(B). The building official enforces the standard as noise control officer, and violations may be abated as a public nuisance under Section 16.20.120.

Violations & Fines

Running construction equipment before 7 a.m., after 7 p.m., or on a Sunday or federal holiday strips the noise exemption, exposing the activity to the zone's standard decibel limits and nuisance abatement.

Frequently Asked Questions

Can construction crews work in Hesperia on Sunday?
The noise exemption for construction, repair, and demolition work applies only 7:00 a.m. to 7:00 p.m.; it does not cover Sundays or federal holidays under HMC § 16.20.125(E)(3).
What happens if a contractor runs equipment at 6 a.m.?
The construction noise exemption no longer applies, so the noise must comply with the zone's regular decibel limits: 55 dB(A) at night in residential districts.
