Moreno Valley's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Moreno Valley, California, there are 7 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.

Aircraft Noise

Moreno Valley controls aircraft noise exposure through land-use compatibility zoning rather than a decibel ordinance. MVMC Section 9.07.060 applies the March Air Reserve Base/Inland Port Airport Land Use Compatibility Plan, including a designated B2 High Noise Zone, to development near the base.

Key details: Governing plan: March ARB/Inland Port Airport ALUCP (2014). High-noise designation: Zone B2, High Noise Zone. Total compatibility zones: 8 (M, A, B1, B2, C1, C2, D, E). State authority: PUC §§ 21670-21679.5. Council override vote: Two-thirds, 45-day notice.

There is no separate fine schedule for aircraft-noise zoning; compliance is enforced through the entitlement process. A general plan amendment, zoning ordinance, or discretionary project approved within the airport influence area without the required ALUC consistency review or finding is subject to challenge and, once built without proper approval, becomes a Title 9 violation under MVMC Section 1.01.200, chargeable as a misdemeanor (up to $1,000 fine and/or six months in jail under Section 1.01.230) or as an infraction at the city attorney's discretion.

This is not one of those rules that cities tend to ignore. Moreno Valley actively enforces its aircraft noise requirements.

Decibel Limits

Moreno Valley caps nonimpulsive sound reaching residential property at 60 dB(A) daytime and 55 dB(A) nighttime, and commercial property at 65 dB(A) daytime and 60 dB(A) nighttime, measured 200 feet from the source. Separate hearing-damage thresholds bar higher levels regardless of zone.

Key details: Residential daytime limit: 60 dB(A). Residential nighttime limit: 55 dB(A). Commercial daytime limit: 65 dB(A). Measured at: 200 feet from source property line. Max fine: $1,000 and/or 6 months jail.

Violating any sound level limit is a misdemeanor punishable by a fine of up to $1,000 and/or six months in county jail, though the citing officer or city attorney may instead prosecute it as an infraction or issue a civil citation under Chapter 1.10. The property owner, tenant, or lessee is jointly responsible along with whoever caused the sound if they knew or should have known of the violation, and a violation can be declared a public nuisance subject to court-ordered abatement or injunction.

Construction Hours

Moreno Valley restricts construction citywide to 7 a.m. to 7 p.m. Monday through Friday and 8 a.m. to 4 p.m. on Saturday under Municipal Code Section 8.14.040(E). No construction is allowed on Sundays or holidays without written approval from the building official or city engineer.

Key details: Weekday hours: 7 a.m. to 7 p.m., Mon-Fri. Saturday hours: 8 a.m. to 4 p.m.. Sunday/holidays: No construction without written OK. Who approves exceptions: Building official or city engineer. Governing code: MVMC Sec. 8.14.040(E).

Construction outside the permitted hours without written approval is a violation of Title 8, enforced by the building official; violations of the Moreno Valley Municipal Code are punishable under the general penalty section, 1.01.230(A), by a fine of up to $1,000, imprisonment in the county jail for up to six months, or both, with each day of a continuing violation treated as a separate offense under Section 1.01.200(B). A building inspector can also refuse to conduct inspections at a site that is out of compliance, and the building official may issue a stop-work order for ongoing violations.

Vehicle Noise

Moreno Valley bans operating any motor vehicle so its sound exceeds the 60/65 dB(A) zone limits when the Vehicle Code doesn't already cover it, and separately caps vehicle stereo systems at plainly audible 50 feet away on public property outside the right-of-way. Fines reach $1,000.

Key details: Stereo audibility limit: Plainly audible at 50 feet. Applies on: Public space/property open to public. Right-of-way vehicles: Governed by CA Vehicle Code instead. Max penalty: $1,000 fine / 6 months jail. Legal basis: MVMC § 11.80.030(D)(1),(3).

A vehicle noise violation is a misdemeanor carrying a fine of up to $1,000 and/or up to six months in county jail, though it may instead be charged as an infraction or resolved through a civil citation under Chapter 1.10 at the discretion of the citing officer or city attorney. The vehicle's driver and any responsible possessor of the vehicle share liability, and repeated violations can support a public nuisance abatement action.

Barking Dogs

Moreno Valley makes it unlawful to keep a dog that "habitually barks, whines or makes loud or unusual noises" enough to disturb neighbors' peace and quiet under Section 10.02.110. The chief animal control officer only investigates a barking complaint once it is submitted in writing and signed by the complainant.

Key details: Governing section: MVMC § 10.02.110. Standard: Disturbs 'ordinary sensitivity' neighbors. Who is liable: Owner or anyone controlling premises. Complaint requirement: Written and signed, not anonymous. Cross-reference: 'Noisy animals' listed in §10.02.100(G)(1).

A violation of Section 10.02.110 is enforced only after a signed, written complaint reaches animal services; the chief animal control officer then investigates and can pursue the same administrative and civil citation remedies available under the rest of Chapter 10.02, including referral for spay/neuter enforcement under Section 10.02.100(G) when the barking dog is also unaltered.

Amplified Music & Outdoor Sound

Moreno Valley caps amplified sound at 60 decibels in city parks and bars stationary or handheld sound equipment anywhere in the city from creating a noise disturbance. Section 11.40.040(V) sets the park decibel limit, while Section 11.80.030(D) regulates radios, loudspeakers and amplifiers on private and public property citywide.

Key details: Park sound limit: 60 decibels from all equipment. Loudspeaker distance rule: 50 feet, plainly audible standard. Outdoor dining rule: Not audible beyond the lot line. Citywide misdemeanor fine: Up to $1,000 and 6 months jail. Governing sections: Sections 11.40.040(V) and 11.80.030(D).

Violating the park amplified sound limit is an infraction under Section 11.40.100(B). Violating Chapter 11.80's citywide noise rules is a misdemeanor under Section 11.80.060, punishable by a fine up to $1,000, up to six months in county jail, or both, though the citing officer or city attorney may instead prosecute it as an infraction or a civil citation under Chapter 1.10.

Quiet Hours

Moreno Valley's noise code defines nighttime as 10:01 p.m. to 7:59 a.m., during which residential sound cannot exceed 55 dB(A) at the property line. Construction, power tools and noncommercial loudspeakers face additional nighttime curfews under Municipal Code Chapter 11.80, enforced by police and code enforcement.

Key details: Nighttime hours: 10:01 p.m. to 7:59 a.m.. Residential nighttime limit: 55 dB(A). Construction/demolition curfew: 8 p.m. to 7 a.m.. Max penalty: $1,000 fine and/or 6 months jail. Measurement point: 200 feet from property line.

Section 11.80.060(A) makes any Chapter 11.80 violation a misdemeanor punishable by a fine up to $1,000 and/or six months in county jail, though the citing officer or city attorney may instead pursue it as an infraction or civil citation under Chapter 1.10. Property owners, tenants, managers or agents share joint and several responsibility with the person causing the sound if they knew or should have known of it, and a violation endangering public health or safety may be declared a public nuisance subject to court-ordered abatement.

The Bottom Line

Moreno Valley'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 Moreno Valley is broadly strict or permissive.
