The Fresno noise ordinance, set out in Chapter 10, Article 1 of the Fresno Municipal Code, limits residential noise to 50 dBA between 10:00 p.m. and 7:00 a.m., 55 dBA in the evening, and 60 dBA during the day, and treats any sound that exceeds the neighborhood’s ambient level by more than five decibels at your property line as a violation. If you live in unincorporated Fresno County rather than inside city limits, a different and stricter ordinance applies.
Decibel Limits by Zone and Time of Day
Section 10-102 sets baseline decibel levels for three types of districts. These figures are the floor. If the actual background noise in your area is already louder than the number below, that higher ambient level becomes the standard.
- Residential, 7:00 a.m. to 7:00 p.m.: 60 dBA
- Residential, 7:00 p.m. to 10:00 p.m.: 55 dBA
- Residential, 10:00 p.m. to 7:00 a.m.: 50 dBA
- Commercial, 7:00 a.m. to 10:00 p.m.: 65 dBA
- Commercial, 10:00 p.m. to 7:00 a.m.: 60 dBA
- Industrial, anytime: 70 dBA
The residential limit drops in two steps as the evening progresses. At 60 dBA during the day, normal conversation and household activity sit well within bounds. The 50 dBA overnight limit is roughly the volume of a quiet office, low enough that a loud stereo, an idling truck, or an industrial fan easily exceeds it. All readings use A-weighted decibels on slow response, which approximates what the human ear actually perceives.1Municode Library.

The Five-Decibel Rule
The table is only the starting point. Under Section 10-106, the actual enforcement trigger is any noise that exceeds the ambient level at the affected person’s property line by more than five decibels. For condominiums and apartments, the measurement point shifts to inside the adjoining living unit.2Municode Library. Fresno Code of Ordinances – Article 1 Noise Regulations – Section 10-106 Prima Facie Violation
In practice, the city doesn’t just compare a noise to a fixed number. If your neighborhood already sits at 55 dBA because of nearby traffic, 55 becomes the baseline, and your neighbor’s noise becomes a violation once it pushes past 60 dBA at the property line. Formal enforcement uses a specified measurement procedure with fifteen-minute averages taken before and during the offending noise, but most complaints about loud parties or blaring music get resolved through officer discretion rather than a full measurement session.3Municode Library. Fresno Code of Ordinances – Article 1 Noise Regulations – Section 10-104 Monitoring
What Kinds of Noise the Ordinance Covers
Section 10-105 makes it unlawful to create any sound that causes “discomfort or annoyance to any reasonable person of normal sensitiveness” in the area. The code lists specific sources that fall under this rule:
- Amplified sound from radios, televisions, musical instruments, stereos, and any other device used to produce or amplify sound or the human voice
- Animals or fowl creating persistent cries or behavioral sounds
- Mechanical equipment such as fans, pumps, air conditioning units, engines, compressors, and generators
- Construction equipment such as pile drivers, hammers, saws, drills, derricks, and hoists
The “reasonable person” standard means enforcement doesn’t hinge on the most noise-sensitive neighbor. Officers weigh duration, frequency, and intensity against what’s normal for the area. A dog barking once at the mail carrier isn’t a violation; a dog barking continuously for hours likely is. Music played in your living room at a normal volume is fine, but if it’s clearly audible across property lines at a level that would bother an average person, it crosses the line.4Municode Library. Fresno Code of Ordinances – Article 1 Noise Regulations – Section 10-105 Excessive Noise Prohibited
Construction and Permitted Work
Section 10-109 exempts construction, repair, or remodeling done under a valid building, electrical, plumbing, or mechanical permit from the standard decibel limits, provided the work happens between 7:00 a.m. and 10:00 p.m. on any day except Sunday. Site preparation and grading fall under the same exemption. Emergency work is exempt at any hour, any day.5Municode Library. Fresno Code of Ordinances – Article 1 Noise Regulations – Section 10-109 Exceptions
Two things trip people up here. The exemption runs until 10:00 p.m., not 7:00 p.m., so a contractor running a saw at 9:00 p.m. on a Tuesday is within the window if a permit covers the work. And the work has to be under a government-issued permit. Weekend yard work with a lawnmower or leaf blower doesn’t come with a building permit, so that noise isn’t covered by this exemption and remains subject to the standard decibel limits and the reasonable-person test.
How To Report a Noise Complaint
For an active disturbance like a loud party happening right now, call the Fresno Police Department non-emergency line at (559) 621-7000. Don’t call 911 unless another crime is also in progress, such as a fight or underage drinking. The dispatcher will ask where the noise is, how many people are involved, and whether anything else illegal appears to be happening. Give your name and contact information so an officer can follow up.6City of Fresno. Neighborhood Nuisances
For ongoing or non-urgent issues, like a neighbor’s persistently noisy equipment or a commercial property generating regular disturbances, report through the city’s FresGO system or by calling 3-1-1. City of Fresno Code Enforcement relies on residents to file reports through those channels, and the reports create a documented record that supports later enforcement action.7City of Fresno.

Penalties for Violations
The noise article itself does not contain its own penalty schedule. Violations are handled under the city’s general enforcement provisions, which can include administrative fines and, for persistent offenders, misdemeanor charges. Because the specific fine amounts sit in the general penalty code rather than in the noise article, the exact dollar figures depend on how the city classifies the offense and whether it escalates through repeated violations.
If you’re dealing with a neighbor who won’t stop after a warning, the documented history matters. Complaints filed through FresGO or 3-1-1 create the paper trail that lets code enforcement move from informal resolution to formal citations.
City of Fresno vs. Unincorporated Fresno County
If your address is in unincorporated Fresno County rather than inside city limits, a separate ordinance applies. The county adopted a new noise control ordinance in 2024 that measures noise by how many cumulative minutes it occurs within any one-hour window:
- 30 minutes or more per hour: 50 dBA daytime / 45 dBA nighttime
- 15 minutes per hour: 55 dBA daytime / 50 dBA nighttime
- 5 minutes per hour: 60 dBA daytime / 55 dBA nighttime
- 1 minute per hour: 65 dBA daytime / 60 dBA nighttime
- Any duration: 70 dBA daytime / 65 dBA nighttime
Daytime runs from 7:00 a.m. to 10:00 p.m. and nighttime from 10:00 p.m. to 7:00 a.m. The county also applies a five-decibel reduction for noise that consists primarily of speech, music, or recurring impulsive sounds like hammering.8County of Fresno. Fresno County Noise Control Ordinance No. 24-021
County penalties are spelled out more explicitly than the city’s. Some violations are infractions; others are misdemeanors carrying up to six months in jail and a fine of up to $1,000. Administrative penalties start at $250 for a first violation, rise to $500 for a second within six months, and reach $1,000 for a third or subsequent violation in that same window.8County of Fresno.

Civil Remedies When Enforcement Doesn’t Work
When code enforcement and police involvement don’t resolve the problem, California law offers a separate path. Under California Civil Code Section 3479, anything “offensive to the senses” or that interferes with the “comfortable enjoyment of life or property” qualifies as a nuisance.9California Legislative Information. California Civil Code 3479
A private nuisance lawsuit requires you to show that the interference is substantial, not just mildly annoying, and that a reasonable person in your position would find it unreasonable. Courts weigh the severity and duration of the noise against the social value of the activity causing it. A successful case can bring money damages or an injunction ordering the noise to stop. California small claims court handles smaller disputes without an attorney. Written complaints, code enforcement reports, and recordings collected over time strengthen any eventual claim.
