Farmington Hills's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Farmington Hills, Michigan, there are 9 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.

Barking Dogs

Animal noise in Farmington Hills is enforced through two parallel authorities: the general Sec. 17-101 noise standard (with residential 60/55/50 dB(A) Table A caps) and Code Chapter 6 (Animals), Article III (Dogs and Other Animals), which addresses dog-control nuisance. The Sec. 17-101(g)(7) exemption for 'the unamplified human voice' does not extend to dog barking, so persistent barking that exceeds the Table A caps - or that constitutes an intermittent / pure-tone unreasonable sound under Sec. 17-101(e) - is enforceable. Oakland County Animal Control / the Farmington Hills Police Department handle complaints.

Key details: Noise Code Authority: Sec. 17-101 + Sec. 17-101(e) intermittent / pure-tone clause. Animal Code Authority: Code Ch. 6 (Animals), Art. III Dogs and Other Animals. Receiving-Property Cap: 60 day / 55 evening / 50 night dB(A) residential. Human-Voice Exemption Scope: Sec. 17-101(g)(7) limited to UNAMPLIFIED HUMAN voice - dogs not covered. County Animal Control: Oakland County Animal Control / Animal Shelter & Pet Adoption Center.

Sec. 17-101 violations are city ordinance infractions; Table A measurements (50 dB(A) at the receiving property line 10 p.m. - 7 a.m.) or Sec. 17-101(e) intermittent-sound findings support citation. Chapter 6 (Animals), Article III dog-control violations are separately citable. Each day of continuing violation is a separate offense. Repeated nuisance findings can trigger Oakland County Animal Control impoundment or dangerous-dog proceedings under MCL 287.286a. MCL 750.167 disorderly persons is the statewide misdemeanor backstop.

Industrial Noise

Industrial-source noise in Farmington Hills is governed by Sec. 17-101(c) Table A using a tiered receiving-property cap: 70 dB(A) anytime where the industrial source is in IRO / LI-1 districts AND all adjacent properties are industrial / business; reduced to 60 dB(A) anytime where any adjacent property is residential. There is no nighttime reduction on the industrial source-class line, but the residential-receiving 50 dB(A) night cap remains the practical adjacent-property test. Sec. 17-101(g)(8) exempts public-works projects. Major Farmington Hills industrial / office-research concentrations include the Twelve Mile / Haggerty / I-275 corridor and the Northwestern Highway / Orchard Lake Road business / office spine.

Key details: Code Authority: Sec. 17-101(c) Table A + Sec. 17-101(e) intermittent / pure-tone. Industrial-to-Industrial Cap: 70 dB(A) anytime (source in IRO/LI-1, all adjacent industrial/business). Industrial-to-Residential Cap: 60 dB(A) anytime (any adjacent residential property). Business / Office Cap: 65 dB(A) day (7a-7p) / 50 dB(A) night (7p-7a). Public Works Exemption: Sec. 17-101(g)(8).

Industrial sources exceeding the Sec. 17-101(c) Table A caps (70 dB(A) industrial-to-industrial, 60 dB(A) industrial-to-residential, 65 dB(A) business-to-business day, 50 dB(A) business night) at the adjacent property line are city ordinance infractions; each day of continuing violation is a separate offense. Sec. 17-101(e) supports citation of intermittent or pure-tone industrial sounds (compressors, chillers, generators) below Table A peaks. Site-plan, conditional-use, and zoning buffer-yard conditions can be separately enforced through Building / Zoning. Public-works projects under Sec. 17-101(g)(8) are exempt. BNSF / CN / CSX rail and FRA train-horn rules are federally preempted. MCL 750.167 is the state misdemeanor backstop.

Quiet Hours

Farmington Hills regulates noise under Code of Ordinances Chapter 17 (Nuisances), Article VII (Pests and Sanitation), Section 17-101 (Noise), adopted by Ord. No. C-10-2004 (8-23-04). Unlike many Michigan cities that rely on a pure reasonableness standard, Farmington Hills codifies a numeric A-weighted decibel table tied to clock-time and zoning district. In residential districts (RA, RP, RC, SP, MH) the maximum permitted sound level at an adjacent property is 60 dB(A) from 7:00 a.m. to 7:00 p.m., 55 dB(A) from 7:00 p.m. to 10:00 p.m., and 50 dB(A) from 10:00 p.m. to 7:00 a.m. - giving the city a de facto residential quiet period of 10:00 p.m. to 7:00 a.m. backed by an enforceable 50 dB(A) cap. MCL 750.167 (disorderly persons) provides the statewide unreasonable-noise backstop.

Key details: Code Authority: Farmington Hills Code Sec. 17-101 (Ch. 17 Nuisances, Art. VII). Enabling Ordinance: Ord. No. C-10-2004 (adopted 8-23-04). Residential Day Cap (7a-7p): 60 dB(A) at adjacent property. Residential Evening Cap (7p-10p): 55 dB(A). Residential Night Cap (10p-7a): 50 dB(A).

Chapter 17 violations are city civil/ordinance infractions enforced through the Farmington Hills Police Department and Special Services. Penalties under Chapter 1 of the Code apply to Chapter 17 violations not otherwise specified, with each day of continuing violation chargeable as a separate offense. MCL 750.167 (Michigan disorderly persons - unreasonable noise) is a parallel state-law misdemeanor available to officers. Special exception relief from Table A is available under Sec. 17-101(f) by application to the Zoning Board of Appeals sitting as an administrative review board.

Outdoor Music

Outdoor music in Farmington Hills is regulated under Sec. 17-101 (Noise) plus the Sec. 17-101(f) special-exception path. The city does not maintain an entertainment-district overlay - all outdoor amplification must stay under Table A caps at the adjacent property line unless a Zoning Board of Appeals special exception is granted. City-sponsored events at Heritage Park (Founders Festival), the Farmington Hills Cultural Arts amphitheater, and the Costick Activities Center operate through special-event permits with conditioned amplification limits. Sec. 17-101(g)(5) exempts outdoor school and playground activities.

Key details: Code Authority: Sec. 17-101 + Sec. 17-101(f) special-exception path. No Entertainment District Overlay: All outdoor music defaults to Table A receiving caps. Residential Receiving Caps: 60 day / 55 evening / 50 night dB(A). School / Playground Exemption: Sec. 17-101(g)(5) - school athletic and entertainment events. Church Bells / Chimes Exemption: Sec. 17-101(g)(6).

Outdoor amplified music exceeding Sec. 17-101(c) Table A at the adjacent property line is a city ordinance infraction; each day is a separate offense. Sec. 17-101(e) intermittent / pure-tone supports citation of bass thumping below Table A peaks. Permit-condition violations (operating outside conditioned hours, exceeding conditioned levels) trigger permit revocation, denial of future permits, and on-scene Police shutdown. Sec. 17-101(g)(5) outdoor school / playground exemption protects school athletic and entertainment events. Sec. 17-101(g)(6) protects church bells / chimes. MCL 750.167 disorderly-persons is the state misdemeanor backstop.

Construction Hours

Section 17-101(g)(1) exempts construction activity from the Table A dB(A) maximums, cross-referencing Section 18-164 (Buildings and Building Regulations) for the operative construction-hour limits. The result is that construction noise during permitted hours is not measured against the residential 60/55/50 dB(A) table - construction operates under the building-code window rather than the Chapter 17 numeric cap. Construction outside the permitted Sec. 18-164 window loses the exemption and is enforceable under the Table A receiving-property dB(A) caps.

Key details: Code Authority: Sec. 17-101(g)(1) exemption + cross-reference Sec. 18-164. Numeric Cap When Exempt: None during permitted hours. Numeric Cap When Outside Window: Residential 60 day / 55 evening / 50 night dB(A) (Table A). Public Works Exemption: Sec. 17-101(g)(8) - public agency maintenance / repair / improvement projects. Special Exception Path: Sec. 17-101(f) Zoning Board of Appeals.

Construction noise outside the Sec. 18-164 permitted window loses the Sec. 17-101(g)(1) exemption and is enforceable under the Table A residential 60/55/50 dB(A) caps at the adjacent property line. Section 17-101(a) and (e) reasonableness violations are city ordinance infractions; building-permit conditions can be separately enforced by stop-work order. MCL 750.167 disorderly-persons charges are a Michigan misdemeanor backstop. Report to Farmington Hills Police non-emergency or Special Services / Building Division.

Farmington Hills is more permissive than most cities when it comes to construction hours. That said, there are still limits.

Leaf Blower Rules

Farmington Hills does not publish a leaf-blower-specific ordinance and does not ban gas-powered blowers. Leaf blower and lawn-equipment use is governed by Sec. 17-101(g)(4), which exempts 'lawn care and yard maintenance' from the Table A dB(A) caps - but only when the activity occurs between 8:00 a.m. and 9:00 p.m. Lawn equipment operated before 8:00 a.m. or after 9:00 p.m. loses the exemption and is enforceable against the residential 60/55/50 dB(A) Table A caps, which effectively bars commercial-grade gas blowers at those hours in residential areas.

Key details: Code Authority: Sec. 17-101(g)(4) lawn care / yard maintenance exemption. Exempt Hours: 8:00 a.m. to 9:00 p.m.. Gas Blower Ban: None. Outside-Window Cap: Table A residential 60 day / 55 evening / 50 night dB(A). State Preemption: None - Michigan has not preempted local leaf-blower rules.

Lawn equipment operation before 8:00 a.m. or after 9:00 p.m. loses the Sec. 17-101(g)(4) exemption and is enforceable against Table A: 60 dB(A) (residential day), 55 dB(A) (residential evening), 50 dB(A) (residential night) at the adjacent property line. Citations are city ordinance infractions; each day is a separate offense. Sec. 17-101(e) supports citation of repetitive lawn-equipment cycles even below Table A on the unreasonable-interference test. HOA covenant violations are civil and enforced by the association. MCL 750.167 (disorderly persons) is the state-law backstop.

Farmington Hills is more permissive than most cities when it comes to leaf blower rules. That said, there are still limits.

Amplified Music & Events

Amplified music in Farmington Hills is regulated under the general Sec. 17-101 noise framework. Sound from amplification systems, bands, DJs, and outdoor PA systems must stay under the Table A dB(A) caps at the adjacent property line: 60 dB(A) (7a-7p), 55 dB(A) (7p-10p), 50 dB(A) (10p-7a) in residential districts; 65 dB(A) day and 50 dB(A) night in business / office districts. Sec. 17-101(g)(7) exempts only the 'unamplified human voice' - amplified speech and amplified music are NOT exempt. Special exception under Sec. 17-101(f) is available from the Zoning Board of Appeals for one-off events.

Key details: Code Authority: Sec. 17-101 + Sec. 17-101(e) intermittent-sound clause + Sec. 17-101(f) special exception. Residential Receiving Cap: 60 day / 55 evening / 50 night dB(A). Business / Office Receiving Cap: 65 day / 50 night dB(A). Exemption Scope: Sec. 17-101(g)(7) limited to UNAMPLIFIED human voice. Special Exception Path: Zoning Board of Appeals (sitting as administrative review board).

Amplified-music violations are Sec. 17-101 ordinance infractions: each day of continuing violation is a separate offense. Citations issue under Table A (residential 60/55/50 dB(A); business 65 day / 50 night) or Sec. 17-101(e) intermittent-sound findings. Bass thumping below Table A peaks can still be cited under the intermittent-sound / pure-tone clause. MCL 750.167 disorderly-persons (unreasonable noise) is the state misdemeanor backstop. Police on-scene shutdown authority is available. Special-exception relief under Sec. 17-101(f) requires Zoning Board of Appeals approval in advance.

Aircraft Noise

Aircraft-in-flight noise is preempted by the Federal Aviation Administration under the Airport Noise and Capacity Act of 1990 (49 U.S.C. 47521 et seq.). Farmington Hills lies approximately 25 miles northwest of Detroit Metropolitan Wayne County Airport (DTW / KDTW) and is regularly overflown by DTW arrivals and departures. Bishop International (FNT) and Oakland County International Airport (PTK / KPTK) in Waterford Township also contribute regional GA and corporate-jet overflight. Sec. 17-101 does not regulate aircraft, and Sec. 17-101(g) practices defer to the federal framework. The DTW Noise Compatibility Program (FAA Part 150) is the public complaint and mitigation channel.

Key details: Local Aircraft Noise Rule: None - federally preempted (FAA / ANCA 1990). Primary Airport: Detroit Metropolitan Wayne County Airport (DTW / KDTW) ~25 mi SE. Airport Operator: Wayne County Airport Authority (WCAA). Secondary GA Airport: Oakland County International Airport (PTK / KPTK), Waterford Township. Noise Program: DTW FAA Part 150 Noise Compatibility Program; ATCT fanning departure procedures.

No city-issued noise citation is possible for aircraft in flight - federally preempted by ANCA 1990 and FAA jurisdiction. Submit DTW aircraft noise complaints through the Wayne County Airport Authority Noise Compatibility Program; submit Oakland County International (PTK) complaints to the Oakland County International Airport administration. The federal community-wide mitigation mechanism is the FAA Part 150 study process. Sec. 17-101 has no aircraft provisions. Military and Coast Guard operations are federally operated and exempt from local enforcement.

The rules around aircraft noise in Farmington Hills lean permissive, but that does not mean anything goes.

Decibel Limits

Farmington Hills is one of the comparatively few Michigan cities with a codified dB(A) limit table. Sec. 17-101(c) Table A sets numeric caps at the adjacent property line by zoning district and time of day, measured with an ANSI-spec A-weighted sound level meter calibrated before and after the reading. Residential receiving (RA, RP, RC, SP, MH): 60 dB(A) 7a-7p, 55 dB(A) 7p-10p, 50 dB(A) 10p-7a. Business / office (OS, B, ES, P): 65 dB(A) 7a-7p, 50 dB(A) 7p-7a. Industrial (IRO, LI-1): 70 dB(A) anytime industrial-to-industrial, 60 dB(A) anytime industrial-to-residential.

Key details: Code Authority: Sec. 17-101(c) Table A; Sec. 17-101(b) measurement method. Residential Day Cap (7a-7p): 60 dB(A). Residential Evening Cap (7p-10p): 55 dB(A). Residential Night Cap (10p-7a): 50 dB(A). Business / Office Day Cap: 65 dB(A) (7a-7p).

Source emissions exceeding Sec. 17-101(c) Table A at the adjacent property line are city ordinance infractions; each day of continuing violation is a separate offense. Sec. 17-101(e) intermittent / pure-tone citations do not require a Table A exceedance. Officers must use ANSI-spec calibrated sound-level meters with A-weighted filters where Table A is invoked. Sec. 17-101(f) special-exception relief is available from the Zoning Board of Appeals. MCL 750.167 disorderly-persons charge is the state-law misdemeanor backstop and does not require a meter reading.

Compared to other cities, Farmington Hills takes a harder line on decibel limits. The enforcement and penalty structure reflects that.

The Bottom Line

Compared to many U.S. cities, Farmington Hills gives residents more room on noise ordinances. 3 of the 9 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

All of the above reflects Farmington Hills's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
