Riverside's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Riverside, California, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Amplified Music & Outdoor Sound

Riverside bans loud music or noise from sound amplifying equipment or a live performance that carries 25 feet or more beyond the property, structure, or unit where it starts. RMC § 7.35.010(D) applies around the clock, there's no daytime carve-out, layered on top of Chapter 7.25's separate decibel limits. Code Enforcement and police cite on a 'plainly audible' distance test, not a meter reading.

Key details: Governing section: RMC § 7.35.010(D). Audibility threshold: Plainly audible 25+ feet from property line. Applies: Any time: no daytime exemption. First-offense fine: $100 administrative citation. Max criminal penalty: $1,000 fine and 6 months jail.

Riverside enforces noise complaints either as a criminal misdemeanor or infraction under RMC § 1.01.110 (up to $1,000 and six months in County jail for a misdemeanor, up to $250 for an infraction) or through administrative citations under Chapter 1.17, $100 for a first offense, $500 for a second, and $1,000 for a third within the same violation type. Each day a violation continues is a separate offense.

Leaf Blower Rules

Riverside does not ban gas leaf blowers, but RMC § 7.35.010(B)(6) prohibits operating any lawn or garden tool between 10 p.m. and 7 a.m., and § 7.35.020(D) limits residential property maintenance to 7 a.m. to 10 p.m.

Key details: Permitted hours: 7 a.m. - 10 p.m.. Prohibited hours: 10 p.m. - 7 a.m.. City-wide gas blower ban: No. Code sections: RMC §§ 7.35.010(B)(6), 7.35.020(D). State backdrop: CARB AB 1346 SORE rule (2024).

Operating a leaf blower or mower outside the 7 a.m.-10 p.m. residential maintenance window, or after 10 p.m./before 7 a.m. when it disturbs neighbors, can trigger Title 7 fines under § 7.15.010 ($500 / $750 / $1,000). Equipment must also be 'sufficiently muffled and maintained so as not to create a noise disturbance' per § 7.35.010(B)(6).

This is not one of those rules that cities tend to ignore. Riverside actively enforces its leaf blower rules requirements.

Aircraft Noise

Riverside bans operating aircraft at the Municipal Airport in a way that causes unnecessary noise, and pilots must follow detailed VFR departure, approach, and pattern-altitude procedures designed to route flights away from housing.

Key details: Core rule: no unnecessary aircraft noise, ground or air. Pattern altitude: 1,800 MSL (2,300 MSL for jets). Missed-approach floor: 1,200 MSL. Sensitive area: avoid Ramona High School, Magnolia Ave.. Governing section: RMC § 12.08.190.

Operating an aircraft at Riverside Municipal Airport in a manner causing unnecessary noise, or disregarding the listed VFR departure, approach, and pattern-altitude procedures, violates RMC § 12.08.190 and is enforceable under the Code's general penalty section, RMC § 1.01.110, as an infraction (up to $250) or misdemeanor (up to $1,000 and/or six months in jail), separately for each day of violation.

Barking Dogs

Riverside doesn't ban barking outright: it runs a formal nuisance process under RMC Chapter 8.10. A dog crosses the line once its barking, howling or crying runs continuously for ten minutes, or intermittently for 30 minutes, on five or more separate days within a 30-day span. Animal Control investigates, issues a written warning notice, and can escalate repeat offenders to a hearing before the City's Administrative Hearing Officer.

Key details: Noise threshold: 10 min continuous or 30 min/5+ days in 30 days. First enforcement step: Written noisy animal warning notice. Hearing timing: Set 10-30 days after complaint. Compliance deadline: 5 days after mailed determination. Enforcing office: Animal Control Director / Hearing Officer.

Ignoring an Administrative Hearing Officer's abatement order is itself unlawful under §8.10.090, exposing the responsible party to administrative citations and administrative civil penalties under RMC Chapter 1.17, plus continued liability for each day the noisy-animal nuisance persists. If those remedies fail, §8.10.095 authorizes the City Attorney to file a civil action in Riverside County Superior Court to force abatement of the nuisance directly.

Construction Hours

Riverside limits permitted construction, repair, remodeling, and grading noise to daytime hours: 7 a.m. to 7 p.m. weekdays and 8 a.m. to 5 p.m. Saturdays. RMC § 7.35.020(G) ties the exemption to holding a valid City permit, work outside those hours, or without one, loses its noise-law exemption. No exemption exists at all on Sundays or federal holidays.

Key details: Weekday construction hours: 7:00 a.m.–7:00 p.m.. Saturday construction hours: 8:00 a.m.–5:00 p.m.. Sunday/holidays: No construction noise exemption at all. Permit required: Valid City permit needed for exemption. Governing section: RMC § 7.35.020(G).

Construction noise outside the permitted hours, or performed without the required City permit, loses its § 7.35.020(G) exemption and can be cited as a noise disturbance under § 7.35.010. Enforcement runs through RMC § 1.01.110 (misdemeanor, up to $1,000 and six months in jail, or a $250 infraction) or Chapter 1.17 administrative citations starting at $100 and rising to $1,000 for repeat violations, with each day a separate offense.

The Bottom Line

Riverside's noise ordinances rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Riverside is broadly strict or permissive.

Keep in mind that Riverside can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
