Noise Ordinances in Folsom, CA: What Residents Actually Need to Know

If you live in Folsom or are thinking about moving there, noise ordinances are one of those things you probably won't think about until they affect you directly. Folsom has 7 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.

Vehicle Noise

Modified exhaust, loud mufflers, and excessive acceleration on Folsom streets violate CA Vehicle Code §27150-27151 (muffler requirement) and §23130 (vehicle noise limits). Folsom Police enforce both state vehicle code and Folsom Municipal Code §8.42 for stationary vehicle noise.

Key details: Muffler Required: CVC §27150. dBA Limit: 80 dBA @ 50 ft (cars). Sideshows: CVC §23109 misdemeanor. Stationary Noise: FMC §8.42. Referee: BAR inspection required.

CVC §27150/27151 citation ~$25-$196 plus referee inspection requirement. Sideshow/exhibition: misdemeanor with vehicle impound up to 30 days.

Decibel Limits

Folsom caps interior noise inside a receiving dwelling unit at 45 dBA daytime and 35 dBA nighttime for sustained sound, with lower thresholds for brief spikes, measured under a strict testing protocol.

Key details: Section: Municipal Code § 8.42.050. Sustained limit, day: 45 dBA (5+ min/hour). Sustained limit, night: 35 dBA (5+ min/hour). Brief spike limit, day: 55 dBA (<1 min/hour). Simple-tone reduction: -5 dBA for tone/speech/music.

The community development director or an authorized deputy serves as enforcement officer under Section 8.42.020 and investigates complaints using the calibrated-meter protocol in Section 8.42.030. A property owner cited for exceeding Table 8.42.050 may apply to the enforcement officer for a variance under Section 8.42.090, with a written decision appealable to the city council within 15 days; violations that are not resolved through a variance are handled as noise disturbances subject to the city's general administrative and criminal enforcement provisions.

Quiet Hours

Folsom exempts residential property maintenance noise, like mowers and power tools, from its general noise limits only between 7 a.m. and dusk on weekdays and 8 a.m. to dusk on weekends, functioning as the city's quiet-hours cutoff for yard and maintenance work.

Key details: Section: Municipal Code § 8.42.060(D). Weekday window: 7 a.m. to dusk. Weekend window: 8 a.m. to dusk. Covers: Residential property maintenance noise. Outside window: General noise standards apply.

A resident who runs maintenance equipment outside the 7 a.m. to dusk weekday or 8 a.m. to dusk weekend windows loses the Section 8.42.060(D) exemption and can be cited for a noise disturbance under the general standards enforced by the community development director. The property owner or operator may seek a variance from the enforcement officer under Section 8.42.090, with a written decision appealable to the city council within 15 days of the enforcement officer's determination.

Construction Hours

Folsom limits construction noise to 7 a.m. to 6 p.m. on weekdays and 8 a.m. to 5 p.m. on Saturday and Sunday; construction noise outside those hours forfeits its exemption and must meet the city's ordinary decibel limits.

Key details: Section: Municipal Code § 8.42.060(C). Weekday hours: 7 a.m. to 6 p.m.. Weekend hours: 8 a.m. to 5 p.m.. Outside hours: Must meet Tables 8.42.040/050. Enforcement officer: Community development director.

Construction noise outside the 7 a.m.-6 p.m. weekday or 8 a.m.-5 p.m. weekend windows is enforced by the community development director as a noise disturbance under the general exterior and interior dBA tables; a contractor or property owner can request a variance under Section 8.42.090, with a written city decision appealable to the city council within 15 days. Repeated violations can be pursued through the city's broader administrative enforcement provisions in Chapters 1.08 through 1.10.

Barking Dogs

Folsom bans letting a dog or other animal make chronic, unprovoked noise that rises to a nuisance, howling, yowling, barking, or whining, under Municipal Code Section 7.04.060, with a carve-out for reasonable noise from licensed veterinary hospitals, shelters, and farm facilities; a violation is an infraction enforced by animal services.

Key details: Governing section: FMC § 7.04.060. Standard: Unprovoked, chronic disturbance. Exemption: Vet hospitals, shelters, farm uses. Charge level: Infraction. Enforcement: Animal services officer.

A violation of Section 7.04.060 is an infraction. Under the general infraction fine schedule at Section 7.02.100, a first violation carries a fine up to $50, a second violation of the same provision within a year up to $100, and a third or further violation within that year up to $250, unless a different fine is specified elsewhere in Title 7.

The rules around barking dogs in Folsom lean permissive, but that does not mean anything goes.

Amplified Music & Outdoor Sound

Folsom bans sound amplifiers in city parks and recreation facilities unless a special permit is obtained first. Section 9.68.020(7) makes using 'any sound amplifiers' in a park an infraction absent that permit, part of a broader list of park-use restrictions enforced under Chapter 9.68 with escalating fines for repeat violations.

Key details: Rule: Sound amplifiers banned in parks without special permit. Governing section: Folsom Municipal Code § 9.68.020(7). Skate park rule: Personal amplified sound barred, director may authorize events. First-offense fine: Up to $50, rising to $250 for repeat violations. Separate track: Private-property amplified noise falls under Chapter 8.42.

Using a sound amplifier in a Folsom park without a special permit is an infraction under Section 9.68.030, punishable by a fine up to $50 for a first violation, $100 for a second violation within a year, and $250 for each additional violation within that year. Parks and recreation staff and code enforcement officers can cite violators on site.

Compared to other cities, Folsom takes a harder line on amplified music & outdoor sound. The enforcement and penalty structure reflects that.

Leaf Blower Rules

Folsom permits leaf blowers during daytime hours only (7 AM-7 PM weekdays, 8 AM-7 PM weekends). California AB 1346 bans sale of new gas-powered leaf blowers statewide as of January 1, 2024. Electric/battery blowers remain legal but subject to noise hour limits.

Key details: Hours: 7 AM-7 PM weekday, 8 AM weekend. Gas Sales: Banned CA-wide 1/1/2024 (AB 1346). Existing Gas Use: Legal but discouraged. Air District: SMAQMD. Ordinance: FMC §8.42 general noise.

Noise citations $100-$500 for use outside hours. No separate fine for gas blower use by homeowners; retail sale violations enforced by CARB.

Compared to other cities, Folsom takes a harder line on leaf blower rules. The enforcement and penalty structure reflects that.
