Noise Ordinances in Bishop, CA: What Residents Actually Need to Know
If you live in Bishop or are thinking about moving there, noise ordinances are one of those things you probably won't think about until they affect you directly. Bishop has 10 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.
Leaf Blower Rules
Bishop does not ban leaf blowers, but its noise ordinance prohibits operating any noise-creating blower or power fan unless the noise is muffled. Loud, unmuffled blower use can be cited as an unlawful noise.
Key details: Code section: BMC 8.12.020(M). Requirement: Blower/fan must be muffled. Outright ban: No; muffling required. Decibel limit: None specified. General standard: No loud, unnecessary noise.
Unmuffled or disturbing blower operation is a prohibited noise under BMC 8.12.020(M), abatable and citable by Code Enforcement/police.
Quiet Hours
Bishop bans any loud, unnecessary or unusual noise that injures the health, peace or safety of others. Construction is expressly allowed only between 7 a.m. and 10 p.m., so nighttime is the city's protected quiet window.
Key details: Code chapter: BMC Chapter 8.12. Construction window: 7 a.m. to 10 p.m.. Night audibility test: 50 ft, 10 p.m.-8 a.m.. Standard: Loud, unnecessary or unusual. State backstop: Penal Code 415.
Enforced as a Municipal Code misdemeanor/infraction abatable nuisance; police respond to disturbances. Penal Code 415 disturbing-the-peace is a separate criminal offense.
Construction Hours
Bishop's noise ordinance carves out construction and repair activity, allowing it only between 7 a.m. and 10 p.m. Building or repairing before 7 a.m. or after 10 p.m. is not shielded and can be cited as unlawful noise.
Key details: Allowed hours: 7:00 a.m. to 10:00 p.m.. Code section: BMC 8.12.010. Applies to: Construction and repair activity. Parking-lot sweepers: No noise before 7 a.m.. Decibel cap: None; nuisance standard.
Work outside 7 a.m.-10 p.m. is enforceable as unlawful noise under Chapter 8.12, abatable and citable through Code Enforcement/police.
Vehicle Noise
Bishop prohibits excessive or unusual motor-vehicle noise, needless horn use and running engines without an effective muffler. Screeching tires, revving, backfiring and loud exhaust are all cited examples of unlawful vehicle noise.
Key details: Code section: BMC 8.12.020(A),(I),(N). Horns: Danger warning only. Exhaust: Effective muffler required. Examples: Screeching, revving, backfiring. Diesel idling: Prohibited if disturbing.
Prohibited noises under BMC 8.12.020(A),(F),(I),(N); citable by Bishop Police, alongside California Vehicle Code muffler/exhaust enforcement.
Barking Dogs
Bishop treats keeping any animal or bird that causes frequent or long, continuous noise disturbing neighbors as an unlawful noise. Persistent barking is a code violation abatable through the city, in addition to Bishop's animal-control rules.
Key details: Code section: BMC 8.12.020(E). Trigger: Frequent or long continuous noise. Standard: Disturbs comfort or repose. Also see: Title 6 Animals; Ch. 8.06 Nuisances. Enforcement: Police / Code Enforcement.
Enforced as a prohibited noise/public nuisance under BMC 8.12.020 and Chapter 8.06; owners may receive abatement notices and citations.
Industrial Noise
Bishop's noise code targets several commercial and industrial sources: parking-lot sweepers before 7 a.m., early garbage collection before 6:30 a.m., unmuffled blowers and engines, and idling diesel trucks or buses that disturb residents.
Key details: Parking-lot sweepers: Not before 7 a.m.. Garbage trucks: Not before 6:30 a.m.. Diesel idling: Prohibited if disturbing. Blowers/engines: Must be muffled. Code section: BMC 8.12.020.
Prohibited noises under BMC 8.12.020(F),(G),(H),(J),(M), abatable as public nuisance and citable by the city.
Aircraft Noise
Bishop's city noise code does not regulate aircraft. Aircraft-in-flight noise is governed by the FAA under federal law, and Bishop Airport is operated by Inyo County, so complaints go to the airport and FAA rather than the city.
Key details: City aircraft rule: None in BMC. In-flight noise: FAA / federal preemption. Local airport: Inyo County-operated. Airport name: Eastern Sierra Regional. Complaints to: Airport / FAA.
No city penalty for aircraft-in-flight noise; complaints route to Inyo County airport management and the FAA.
Amplified Music & Events
Bishop prohibits playing radios, instruments or sound devices so as to disturb neighbors' peace and quiet. Sound plainly audible 50 feet away between 10 p.m. and 8 a.m. is prima facie evidence of a violation.
Key details: Code section: BMC 8.12.020(B). Night audibility test: 50 ft, 10 p.m.-8 a.m.. Daytime standard: Must not disturb neighbors. Advertising sound: Prohibited (8.12.020(C)). Decibel meter: Not required.
A prohibited noise under BMC 8.12.020(B); the 50-foot/10 p.m.-8 a.m. audibility test supports citation and abatement.
Decibel Limits
Bishop's noise code sets no numeric decibel limits. Instead it uses a plainly-audible-at-50-feet standard for nighttime amplified sound and a general prohibition on loud, unnecessary or unusual noise disturbing neighbors.
Key details: Decibel limits: None in Bishop code. Primary test: Plainly audible at 50 feet. When: 10 p.m. to 8 a.m.. General rule: No loud/unnecessary noise. Code chapter: BMC Chapter 8.12.
Enforcement rests on the disturbance and 50-foot audibility tests in BMC 8.12.010-8.12.020, not on decibel readings.
Outdoor Music
Bishop bars casting amplified sound onto the street for commercial advertising and prohibits any outdoor music or sound device that disturbs neighbors. Nighttime outdoor sound plainly audible 50 feet away is presumptively unlawful.
Key details: Advertising sound: Prohibited (8.12.020(C)). Outdoor amplified music: Not to disturb neighbors. Night test: Audible 50 ft, 10 p.m.-8 a.m.. Code section: BMC 8.12.020(B),(C). Loudspeakers: Regulated outdoors.
Prohibited noises under BMC 8.12.020(B)-(C); abatable and citable, especially advertising sound cast onto public streets.
