Detroit noise ordinance: quiet hours, limits and complaints

Last updated: August 11, 2026

Quiet hours in Detroit

Between 10:00 p.m. and 7:00 a.m. anywhere in the city, Sec. 16-1-13(a) makes it unlawful to produce "non-motor vehicle noise" (sound plainly audible 50 feet away) by playing or reproducing music — vocals, instruments, speakers of any type, music players, televisions or mobile devices — by amplifying speech through a microphone, megaphone, bullhorn or other sound magnification device, or by using steam or compressed-air whistles or sirens. Construction has its own carve-out in the same section rather than separate daytime hours: Sec. 16-1-13(b) bans heavy construction equipment (pile drivers, jackhammers, drills or any other mechanical apparatus in building or construction operations) and the loading and unloading of vehicles or storage containers between 10:00 p.m. and 7:00 a.m., but only inside a residential zoning district or a district immediately adjoining one. Outside those hours the catch-all in Sec. 16-1-12 still applies at any time of day, and the motor-vehicle rules in Division C run 24 hours a day with no time window at all. 10:00 p.m. and 7:00 a.m. are the only clock times that appear anywhere in Chapter 16.

Decibel limits — or rather, the lack of them

There are none. Detroit's noise article contains no decibel figure of any kind — no sound-level table, no zoning-based dB limits, no meter or measurement procedure. I searched the live text of Chapter 16 and of zoning Article XII and Article XIV: the strings "decibel", "dB", "dBA" and "sound level" return zero matches in all three. The entire standard is distance-based audibility. Sec. 16-1-1 defines "Non-motor vehicle noise" as sound "plainly audible within 50 feet of its source" and "Motor vehicle noise" as sound "plainly audible at a distance greater than ten feet from the motor vehicle." The zoning code's own noise performance standard, Sec. 50-14-587(1), does not add numbers either — it points straight back to Chapter 16 ("The City's noise standards are provided for in Article I of Chapter 16 of this Code, Environment"). Do not attribute a decibel number to Detroit; the closest thing to a numeric standard in the whole scheme is a 150-foot separation for outdoor speakers (Sec. 50-14-587(2)) and a vibration displacement table in inches (Sec. 50-14-588), neither of which is a sound-level limit.

What the ordinance actually says

Sec. 16-1-1 (Definitions): "Non-motor vehicle noise means sounds emitted from any source other than a motor vehicle that can be attributed to a person that is plainly audible within 50 feet of its source."

Sec. 16-1-1 (Definitions): "Motor vehicle noise means any sounds emitted from a motor vehicle, either by its physical or electrical components, or by noise-emitting instruments or devices within it, that are plainly audible at a distance greater than ten feet from the motor vehicle."

Sec. 16-1-12 (General prohibition of noise): "It is unlawful for any person to create, assist in creation, permit, continue or permit the continuance of any unreasonably loud or disturbing noise which annoys disturbs, injures, or endangers the health, peace, safety, or welfare of others within the corporate limits of the City." (the missing comma after "annoys" is in the codified text)

Sec. 16-1-13(a) (Specific prohibitions of activities constituting noise violations): "It is unlawful to engage in, assist in, permit, continue or permit in the continuance of any of the following activities within City limits where the activity produces non-motor vehicle noise between the hours of 10:00 p.m. and 7:00 a.m. unless exempted by Section 16-1-14 of this Code: (1) The performance or reproduction of music through vocals, musical instrument or instruments, speakers of any type, music players, televisions, or mobile devices; (2) The amplification or reproduction of speech through use of a microphone, megaphone, bullhorn, any other sound magnification device; or (3) The use of any steam or compressed air whistles or sirens."

Sec. 16-1-13(b): "It is unlawful to engage in, assist in, permit, continue or permit in the continuance of any of the following activities within a zoning district classified for residential use or immediately adjoined by a zoning district classified for residential use where the activity produces non-motor vehicle noise between the hours of 10:00 p.m. and 7:00 a.m. unless exempted by Section 16-1-14 of this Code: (1) The use of heavy construction equipment including pile drivers, jackhammers, drills, or any other mechanical apparatus in building or constructions operations; or (2) The loading and unloading of vehicles or storage containers." ("constructions operations" is as printed in the code)

Sec. 16-1-11 (Applicability, non-motor vehicle noise): "The provisions of this division apply to all sources of sound except: (1) Motor vehicles in operation on a public right-of-way; (2) Aircraft in flight or in operation at the Coleman A. Young Municipal Airport; (3) Railroad equipment in operation on railroad rights-of-way."

Other provisions that prohibit motor vehicle noise, and the penalties for violation thereof, are contained in the Michigan Vehicle Code, being MCL 257.1 et seq., which is incorporated by reference into this Code through Section 46-3-1, Adoption of Michigan Vehicle Code."

Sec. 16-1-22 (General prohibition of motor vehicle noise): "It is unlawful for any person to produce or reproduce motor vehicle noise as defined in Section 16-1-1 of this Code unless pursuant to an exemption to this division."

Sec. 16-1-23 (Specific prohibitions of motor vehicle noise): "It is a noise violation to produce or reproduce motor vehicle noise by the following means: (1) The use of a horn or warning device within a motor vehicle for purposes other than to warn other drivers of an emergency; (2) Any use of a siren, whistle, or bell in a motor vehicle unless otherwise permitted in this Code; or (3) The production or reproduction of sound within or around a motor vehicle, including the use of internal or external speakers, while a motor vehicle is in motion or at rest."

Sec. 16-1-2(a) (Violations and penalties): "A person who violates any provision of this article is guilty of a misdemeanor for each violation, and, in the discretion of the court, may be fined up to $500.00 and sentenced to a maximum of 90 days in jail, or both, for each violation, except for a violation of Section 16-1-23 of this Code."

Sec. 50-14-587(1) (Zoning, operational performance standards — Noise): "General. The City's noise standards are provided for in Article I of Chapter 16 of this Code, Environment;"

Sec. 50-12-407(b) (Zoning, urban agriculture — motorized equipment): "Motorized equipment within a residential zoning district or residential planned development district shall be restricted to hours beginning at 8:00 a.m. and ending at 8:00 p.m. Equipment, such as fans, necessary for the operation of greenhouses is exempted from this provision."

How to file a noise complaint in Detroit

Call the Detroit Police Department's Telephone Crime Reporting (T.C.R.) non-emergency number at (313) 267-4600. Detroit routes noise to the police rather than to a 311-style service line: detroitmi.gov's Report Crime page lists "Make a noise complaint" verbatim among the reasons to call that number, alongside reporting an abandoned vehicle and neighbor trouble. Use 911 only for an emergency or a crime in progress. Because the standard is audibility rather than decibels, a useful complaint records the time, the address you were standing at, and the fact that the sound was plainly audible from roughly 50 feet away (about ten feet, for a vehicle on a public street) — no sound-meter reading is required and none will be taken. Noise is charged as a misdemeanor, so persistent problems can also be raised with your City Council district office. The Improve Detroit app handles infrastructure and property-condition reports (potholes, illegal dumping, abandoned vehicles, running water, trees) and does not carry a noise category.

Worth knowing

Renumbering trap: the noise ordinance is widely cited online as "Chapter 36," which was correct under the 1984 Code. The Municode editor's note confirms that Ord. No. 02-16, § 2, adopted November 17, 2015 (eff. 2-3-2016), "amended Chapter 36 of the 1984 Code in its entirety to read as herein set out," and the December 2019 recodification moved it to Chapter 16 (Environment), Article I, Secs. 16-1-1 through 16-1-24. Any page still quoting the pre-2016 Chapter 36 — including its old outdoor-speaker permit scheme and 250-foot residential rule — is quoting repealed text. The current article has no speaker-permit regime at all. The version of the ordinance circulating as a PDF on nonoise.org is that repealed 2016-era text. Vehicle rules run 24/7 but only on the public right-of-way. Sec. 16-1-22 makes producing "motor vehicle noise" (plainly audible more than ten feet from the vehicle) unlawful at any hour with no quiet-hours window, and Sec. 16-1-23(3) reaches a car stereo "while a motor vehicle is in motion or at rest." Important scope limit that is easy to miss: Sec. 16-1-21 says Division C "apply only to motor vehicles in operation on a public right-of-way." A car blasting a stereo in a private driveway or a parking lot therefore falls outside Division C and is judged under the Division B 50-foot / 10 p.m.-7 a.m. rules instead. Penalties are separately scheduled, and the escalating fines apply only to Sec. 16-1-23 (the specific motor-vehicle prohibitions), not to the article generally: Sec. 16-1-2(b) sets minimum fines of $100 for a first conviction, $200 for a second, and $300 plus up to 90 days in jail for a third or subsequent conviction. Every other violation of the article is a misdemeanor punishable under Sec. 16-1-2(a) by up to $500 and/or 90 days. Coverage gaps: Division B expressly does not apply to motor vehicles operating on a public right-of-way, aircraft in flight or operating at Coleman A. Young Municipal Airport, or railroad equipment on railroad rights-of-way (Sec. 16-1-11). Complaints about planes at City Airport or trains therefore have no municipal hook. Exemptions, stated precisely. Sec. 16-1-14 exempts "essential services" and "emergency services" as defined in Sec. 16-1-1, but only "to the extent they would constitute a noise violation pursuant to Section 16-1-13" — it does not exempt anyone from the Sec. 16-1-12 general prohibition. The essential-services definition is broad, covering utility and municipal construction and maintenance plus Michigan Department of Transportation work including resurfacing, restriping and emergency repairs, so overnight roadwork and utility digs are lawful under Sec. 16-1-13. On the vehicle side, Sec. 16-1-24 exempts only from Sec. 16-1-23 and covers emergency services and the reasonable use of sirens, bells or whistles by a historic vehicle in an authorized parade — it does not extend the essential-services exemption to vehicles. State law interacts rather than preempts: Sec. 16-1-21 notes that additional motor-vehicle noise provisions sit in the Michigan Vehicle Code, MCL 257.1 et seq., which Detroit incorporates by reference through Sec. 46-3-1. State vehicle rules run alongside the city's ten-foot test. The state statute does contain sound-level figures, but they are state vehicle-equipment standards and must never be presented as Detroit's limit. Scattered provisions outside Article I, all confirmed in Chapter 16's own cross-reference list: noisy animals are a public nuisance abatable under Sec. 6-1-7; alarms that keep sounding are a nuisance under Sec. 31-8-2 and must cut off within one hour under Sec. 31-8-4; loud music at a public dance hall is grounds to suspend or revoke the license (Sec. 5-10-29(b)); amplification-device violations are grounds to close down a carnival (Sec. 5-4-6); "sound cars" are barred from certain areas (Sec. 46-4-111); zoning Sec. 50-14-587(2) bars outdoor paging systems and speakers within 150 feet of R1-R6 or residential PD land or of a school or licensed child care center, with a narrow exception for drive-up teller windows under a porte cochere; and zoning Sec. 50-12-407(b) limits motorized equipment to 8:00 a.m.-8:00 p.m. in residential and residential PD districts, though that section sits in the urban-agriculture subdivision (its neighbours are Sec. 50-12-406 on agricultural nuisance and Sec. 50-12-409 on compost piles) and applies to those operations, not to household lawn care generally. There is no citywide leaf-blower or lawn-equipment ordinance. Pending but not yet codified: Ord. No. 2024-52 (adopted 12/20/24) adds a new zoning Sec. 50-14-486, "Noise," within a solar-generation-station design-standards subdivision. It is solar-specific and does not change the residential picture. No uncodified ordinance touches Chapter 16.

Document it before you report it

Detroit enforces mostly by audibility, but a log of measured levels still makes a complaint concrete and credible. Take a quick reading with the free online decibel meter — it runs in your browser and records nothing — and check how loud your block is on the Detroit noise map. For time-stamped measurement history you can show a landlord or code officer, the app keeps a log.
