Michigan Noise Laws (2026): Quiet Hours, Exhaust Limits, Fines

Michigan law puts decibel limits on vehicle noise statewide. Vehicles may not exceed decibel limits measured at 50 feet, such as 82 dBA where the speed limit is over 35 mph and 76 dBA where it is 35 mph or less for vehicles outside the statute's separately listed classes (MCL 257.707c), and the state occupies "the whole field of vehicle noise regulation" (257.707e(2)). In state parks, recreation areas, forest campgrounds and pathway trailheads, Department of Natural Resources rules set quiet hours from 10 p.m. to 8 a.m. (Mich. Admin. Code R 299.921(n), 299.927(r)). State law also sets muffler and decibel limits for motorboats, snowmobiles and off-road vehicles (MCL 324.80156, 324.82126, 324.81133). Quiet hours for homes, and rules on parties, barking dogs and construction hours, come from city, township and village ordinances where they exist.

Michigan noise laws at a glance

Michigan's vehicle noise limits

Exhaust systems. "A motor vehicle, while being operated on a highway or street, shall be equipped with an exhaust system in good working order to prevent excessive or unusual noise and shall be equipped to prevent noise in excess of the limits established in this act" (MCL 257.707b(1)).

Decibel limits. "A motor vehicle must not be operated or driven on a highway or street if the motor vehicle produces total noise exceeding 1 of the following limits at a distance of 50 feet" (MCL 257.707c(1)). For "a motor vehicle or a combination of vehicles towed by a motor vehicle not covered in subdivision (a) or (b)," the limits are "Eighty-two DBA if the maximum lawful speed on the highway or street is greater than 35 miles per hour" and "Seventy-six DBA if the maximum lawful speed on the highway or street is not more than 35 miles per hour" (257.707c(1)(c)). Motorcycles and mopeds are limited to 86 DBA where the speed limit is over 35 mph and 82 DBA at 35 mph or less (95 DBA on a stationary run-up test at 75 inches), and vehicles of 8,500 pounds or more to 90 and 86 DBA (88 DBA on a stationary run-up test) (257.707c(1)(a), (b)). Other vehicles also may not exceed 95 DBA on a stationary run-up test 20 inches from the end of the tailpipe (257.707c(1)(c)(iii)).

Muffler equipment. "A person shall not operate a vehicle on a highway or street if the vehicle has a defect in the exhaust system that affects sound reduction, is not equipped with a muffler or other noise dissipative device, or is equipped with a cutout, bypass, amplifier, or a similar device" (257.707c(3)).

Penalty. "A person who violates this section is responsible for a civil infraction and shall be ordered to pay a civil fine of not more than $100.00" (257.707c(7)). The court also orders costs, which "must not be ordered in excess of $100.00" (MCL 257.907(4)). A violation of 257.707b or 257.707c(1), (3) or (5) is a civil infraction (257.707d(2)). In court, "If it is shown that the noise level of a motor vehicle is in excess of the DBA levels established in this act, that evidence shall be prima facie evidence that the motor vehicle was producing excessive noise in violation of this act" (257.707d(4)).

Local vehicle noise rules must match the state's. "This act occupies the whole field of vehicle noise regulation. A city, county, village, or township shall not adopt or enforce vehicle noise rules unless the rules are identical to the requirements of this act" (MCL 257.707e(2)).

Horns. "The driver of a motor vehicle shall when reasonably necessary to insure safe operation give audible warning with his horn but shall not otherwise use the horn when upon a highway" (MCL 257.706).

Boats, snowmobiles and off-road vehicles

Motorboats. "A person shall not operate a motorboat on the waters of this state unless the motorboat is equipped and maintained with an effective muffler or underwater exhaust system that does not produce sound levels in excess of 90 dB(A) when subjected to a stationary sound level test as prescribed by SAE J2005 or a sound level in excess of 75 dB(A) when subjected to a shoreline sound level measurement procedure as described by SAE J1970" (MCL 324.80156(1)). A violation is a state civil infraction with "a civil fine of not more than $150.00"; "A person who violates this section a second or subsequent time is guilty of a misdemeanor, punishable by imprisonment for not more than 90 days and a fine of not less than $100.00 or more than $500.00" (324.80156(6)). Official speed trials and sanctioned races under a permit, manufacturer testing and historic vessels are excepted (324.80156(4)).

Snowmobiles. A snowmobile must have "a muffler in good working order and in constant operation from which noise emission does not exceed" 78 decibels at 50 feet for a snowmobile manufactured after July 1, 1977, or 88 decibels stationary for one manufactured after July 1, 1980, under the SAE standards the statute names (MCL 324.82126(2)). Organized races on a course used solely for racing, and race preparation on private property with the owner's permission in compliance with local noise ordinances, are exempt (324.82126(3)).

Off-road vehicles. An individual may not operate an ORV without a spark arrester type muffler approved by the U.S. Forest Service, and "Exhaust noise emission shall not exceed 86 Db(A) or 82 Db(A) on a vehicle manufactured after January 1, 1986, when the vehicle is under full throttle, traveling in second gear, and measured 50 feet at right angles from the vehicle path" (MCL 324.81133(1)(f)).

Quiet hours in Michigan state parks and on state land

The Department of Natural Resources' State Land Use Rules define "Quiet hours" as "the hours between 10 p.m. and 8 a.m. during which time an individual may not knowingly cause noise that disturbs another" (R 299.921(n)). In state parks, recreation areas, forest campgrounds and pathway trailheads, the rules make it unlawful to "Knowingly cause any noise that may disturb another during quiet hours" (R 299.927(r)).

At any hour, on land owned or under the control of the department, it is unlawful to "Engage in any violent, abusive, loud, boisterous, vulgar, lewd, or otherwise disorderly conduct" (R 299.922(e)) or to "Use a loudspeaker, public address system, or sound-amplifying equipment of any kind without written permission, except for an electronic game-calling device that is lawfully used while hunting, or to operate a motor, motorboat, motor vehicle, radio, television, generator, or any other device in a manner that produces excessive noise" (R 299.922(o)).

The DNR's camping FAQ for state parks restates: "Quiet hours are between 10 p.m. and 8 a.m." It adds: "The use of fuel-powered generators is not allowed during established quiet hours (10 p.m. to 8 a.m.)."

A person who violates a DNR rule "is responsible for a state civil infraction and may be ordered to pay a civil fine of not more than $500.00" (MCL 324.504(14)).

Does Michigan have statewide quiet hours for homes?

Apart from the DNR rules for state land, none of the statutes on this page sets quiet hours for homes, construction hours or a decibel limit for a neighbor's music. Those rules come from local ordinances.

Townships. A township board "may adopt ordinances regulating the public health, safety, and general welfare of persons and property, including, but not limited to," a list of subjects such as fire protection, traffic and public amusements, "and may provide sanctions for the violation of the ordinances" (MCL 41.181(1)). Noise is not named in that list, which is open-ended.

Cities. A city may "pass all laws and ordinances relating to its municipal concerns subject to the constitution and general laws of this state" (MCL 117.4j(3)). The penalty for violating a city ordinance, other than a municipal civil infraction ordinance, "must not exceed a fine of $500.00 or imprisonment for 90 days, or both" (117.4i(k)).

Municipal civil infractions. "Whether or not authorized by the city charter, the legislative body of a city may adopt an ordinance that designates a violation of the ordinance as a municipal civil infraction and provides a civil fine for that violation" (MCL 117.4l(2)). An ordinance may not make an act a municipal civil infraction if that act is a crime under, among other laws, the Michigan penal code, the Michigan vehicle code, or "Any law of this state under which the act or omission is punishable by imprisonment for more than 90 days" (117.4l(3)). When a court finds a person responsible for a municipal civil infraction, "Costs of not more than $500.00 shall be ordered," and the judge or magistrate also orders a justice system assessment of $10.00 in addition to any fine or costs (MCL 600.8727).

Fireworks. A local unit of government may adopt an ordinance "prescribing the hours of the day or night during which a person may ignite, discharge, or use consumer fireworks," but the ordinance "shall not regulate the ignition, discharge, or use of consumer fireworks" after 11 a.m. on December 31 (until 1 a.m. on January 1), the Saturday and Sunday immediately before Memorial Day and before Labor Day, June 29 to July 4, and July 5 if it is a Friday or Saturday (until 11:45 p.m. on those days) (MCL 28.457(2)). Such an ordinance "shall impose a civil fine of $1,000.00 for each violation of the ordinance and no other fine or sanction" (28.457(3)).

To find and use your local rules:

• Read the code. Look up your city, township or village code of ordinances, usually linked from the municipal website or available from the clerk, and check the noise, nuisance or public peace chapter.
• Who to call. The local police or sheriff's non-emergency line takes complaints about ongoing disturbances; an ordinance enforcement or code compliance office may handle recurring problems.

Is a loud neighbor disorderly conduct in Michigan?

Not under any general noise clause. Michigan's disorderly person statute, MCL 750.167(1), lists specific kinds of disorderly persons. The categories closest to noise are "A person who is intoxicated in a public place and who is either endangering directly the safety of another person or of property or is acting in a manner that causes a public disturbance" (750.167(1)(e)) and "A person who is engaged in indecent or obscene conduct in a public place" (750.167(1)(f)). None of the listed categories is phrased in terms of loud or unreasonable noise. "Except as provided in subsection (2), a person convicted of being a disorderly person is guilty of a misdemeanor punishable by imprisonment for not more than 90 days or a fine of not more than $500.00, or both" (750.168(1)).

Subsection (2) covers funerals. Within 500 feet of a funeral, memorial service, viewing, procession or burial, a person may not "engage in any conduct intended to disrupt the funeral, memorial service, viewing, procession, or burial and that disrupts" it (MCL 750.167d(1)(c)). A violator is a disorderly person guilty of a felony punishable by up to 2 years, a fine of up to $5,000, or both, or up to 4 years, a fine of up to $10,000, or both after a prior 167d conviction (750.168(2)).

A separate statute covers public disturbances: "Any person who shall make or excite any disturbance or contention in any tavern, store or grocery, manufacturing establishment or any other business place or in any street, lane, alley, highway, public building, grounds or park, or at any election or other public meeting where citizens are peaceably and lawfully assembled, shall be guilty of a misdemeanor" (MCL 750.170). It prescribes no penalty of its own, so the general misdemeanor rule applies: "imprisonment for not more than 90 days or a fine of not more than $500.00, or both" (750.504). The statute speaks of a "disturbance or contention" in the places it lists, not of noise as such.

For a loud neighbor at home, the usual tool is the local noise or nuisance ordinance.

Suing a neighbor over noise

"All claims based on or to abate nuisance may be brought in the circuit court. The circuit court may grant injunctions to stay and prevent nuisance" (MCL 600.2940(1)). "When the plaintiff prevails on a claim based on a private nuisance, he may have judgment for damages and may have judgment that the nuisance be abated and removed unless the judge finds that the abatement of the nuisance is unnecessary" (600.2940(2)). The statute does not define nuisance or mention noise.

If the noise comes from a rental unit, the lease and the landlord may also matter; see Michigan landlord-tenant laws for the rental basics. For fireworks, see Michigan fireworks laws.

Shooting ranges and farms

Shooting ranges. Under the Sport Shooting Ranges Act, a person who owns, operates or uses a sport shooting range that conforms to generally accepted operation practices "is not subject to an action for nuisance, and a court of the state shall not enjoin or restrain the use or operation of a range on the basis of noise or noise pollution, if the range is in compliance with any noise control laws or ordinances that applied to the range and its operation at the time of construction or initial operation of the range" (MCL 691.1542(2)). Subsection (1) gives the same protection against civil liability and criminal prosecution over noise. In addition, "Rules or regulations adopted by any state department or agency for limiting levels of noise in terms of decibel level which may occur in the outdoor atmosphere do not apply to a sport shooting range exempted from liability under this act. However, this subsection does not restrict the application of any provision of the generally accepted operation practices" (MCL 691.1542(3)).

Farms. Under the Right to Farm Act, "A farm or farm operation shall not be found to be a public or private nuisance if the farm or farm operation alleged to be a nuisance conforms to generally accepted agricultural and management practices according to policy determined by the Michigan commission of agriculture" (MCL 286.473(1)). The subsection does not name noise; it covers public and private nuisance claims.
