Quiet Hours
The City of Merced has no citywide quiet-hours decibel ordinance. The only codified time-based limit is the industrial zoning standard (MMC 20.12.030), barring noise beyond the property line of residentially-abutting uses from 10 p.m. to 7 a.m. Late-night disturbances are handled via the Disruptive Parties chapter (MMC 9.64) and California Penal Code 415.

Some RestrictionsConstruction Hours
The City of Merced Municipal Code does not set citywide construction-hours limits; a full-text code search returns no construction-hours provision. Construction noise is limited project-by-project through conditions of approval (site plan review, interface and temporary-use permits) and the General Plan Noise Element, not a fixed start/stop time in the code, unlike cities that codify a 7 a.m.–6 p.m. window.

Few RestrictionsBarking Dogs
Merced has a real, codified barking-dog rule. Under MMC 6.04.040(C), no owner may permit an animal to make loud or disturbing noises without provocation, including chronic howling, yowling, barking, or whining. Persistent animal noise is an 'animal nuisance' (MMC 6.04.010(D) and 6.04.280), enforced by the Animal Control division of the Merced Police Department through a sworn complaint and abatement-hearing process.

Some RestrictionsLeaf Blower Rules
The City of Merced has no leaf-blower ordinance. A full-text Municipal Code search returns zero results for 'leaf blower'—no city ban, decibel cap, or hours restriction. Gas blowers are instead governed by California's statewide small off-road engine zero-emission law (Health & Safety Code 43018.11), and blower noise can be addressed as a general nuisance.

Few RestrictionsAmplified Music & Events
Merced has no general decibel ordinance for amplified music, but it regulates amplified sound in specific settings. Sound amplification in city parks requires an exclusive-use permit and must not unreasonably detract from public enjoyment (MMC 14.08.020-14.08.030). Advertising vehicles with loudspeakers need a City Council permit (MMC 10.12.154). Disruptive amplified gatherings on private property fall under MMC 9.64.

Some RestrictionsAircraft Noise
The City of Merced does not regulate aircraft noise directly; flight operations are federally preempted. The code adopts FAA air-traffic and flight rules by reference for the Merced Regional Airport (MMC 2.32.030, 2.32.050). The city manages noise through land use: the Airport Environs (/AE) overlay requires nearby development to follow the County Airport Land Use Compatibility Plan (MMC 20.22.020).
