How Nashville Handles Noise Ordinances: A Practical Guide

Nashville maintains 167 local ordinances across all categories, and 7 of those deal specifically with noise ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Nashville falls on the strict-to-permissive spectrum compared to other cities.

Aircraft Noise

Metro's citywide noise ordinance does not cover aircraft or airport operations. Title 9 expressly exempts airport uses from every decibel and hour limit it sets.

Key details: Governing provision: Metro Code § 9.10.030. What it says: Title 9 does not apply to airport uses. Airport oversight instead: Metro Nashville Airport Authority, Ch. 2.60. Enforcement under Title 9: None: airport uses excluded.

Not applicable. Title 9's penalties and enforcement (Metro Police, NDOT, Codes and Building Safety) do not reach airport uses under this exemption.

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

Decibel Limits

Metro Nashville caps overnight noise from business equipment, vehicles, and heavy machinery at 70 Db(A) near residential structures, rising to an 85 Db(A) ceiling for facilities in the DTC and contiguous CF zoning districts, between 9:00 p.m. and 6:00 a.m.

Key details: Standard nighttime limit: 70 Db(A), 9 p.m.–6 a.m.. DTC/CF district limit: 85 Db(A), same hours. Measurement point: 4 ft, nearest residential wall. Enforcement agencies: Police, NDOT, Codes and Building Safety. Exempt: Emergency, metro, and utility vehicles.

Exceeding the 70 Db(A) (or 85 Db(A) in DTC/CF zones) overnight limit is a Title 9 noise violation enforced by Metro Police, NDOT, and Codes and Building Safety; each incident of excess noise is a separate offense.

Amplified Music & Outdoor Sound

Metro Nashville bans sound amplification equipment audible from a neighbor's property line, but downtown's DTC district follows numeric decibel limits instead.

Key details: Standard outside DTC: plainly audible at property line. DTC/CF business-hours limit: 85 Db(A) at 50 feet. DTC/CF after-hours limit: 70 Db(A) at 50 feet. Live music in DTC/CF: exempt from 85 Db(A) cap. Enforcement: MNPD, NDOT, Codes and Building Safety.

Playing amplified sound audible from a neighbor's property line breaks the rule regardless of the actual decibel level; the Metro Nashville Police Department, Nashville DOT, and Codes and Building Safety enforce and can cite violators.

Quiet Hours

Metro Nashville bars business and commercial noise above 70 Db(A) near homes between 9 p.m. and 6 a.m., with a relaxed 85 Db(A) limit inside downtown DTC/CF zoning districts.

Key details: Curfew hours: 9:00 p.m. to 6:00 a.m.. Standard limit: 70 Db(A) at residential wall. DTC/CF district limit: 85 Db(A). Applies to: Business/commercial activity, not residents. Enforced by: Metro Police, Codes, NDOT.

No fixed fine is set in this section; Metro Police, Metro Codes Administration, and NDOT enforce Title 9 noise violations, and penalties are set under the general Title 9 enforcement and penalty provisions.

Vehicle Noise

Metro Nashville bans loud mufflers, cut-out exhaust and car stereos audible 50+ feet from the vehicle or 200+ feet for exhaust noise.

Key details: Muffler: Required, in good working order. Exhaust audibility limit: 200 feet or into a dwelling. Stereo/amp audibility limit: 50 feet from vehicle. Minimum fine: $50 per violation. Exempt: Emergency and Metro-owned vehicles.

Minimum $50 fine per Metropolitan Code of Laws § 9.20.020(A)(7); each violation is charged as a separate offense, and police can cite both muffler and stereo-volume violations independently.

Barking Dogs

Metro Nashville bans keeping any dog, bird, or animal whose frequent or loud continued noise disturbs neighbors' comfort: a violation is a public nuisance enforceable by court injunction, per Metropolitan Code of Laws § 8.12.010.

Key details: Citation: Metropolitan Code of Laws § 8.12.010. Prohibited conduct: Frequent or loud continued animal noise. Enforcement: Court injunction, not a fixed fine. Coverage: Metro Nashville-Davidson County, not satellite cities.

A violation is declared a public nuisance; any court of competent jurisdiction can enjoin it, ordering the noise stopped under Metropolitan Code of Laws § 8.12.010(B).

Construction Hours

Metro Nashville bans outdoor construction, repair, or demolition work between 7:00 p.m. and 7:00 a.m. citywide (except on IWD, IR, and IG zoned parcels), tightening to 8:00 p.m.-6:00 a.m. in summer and in three downtown subdistricts year-round.

Key details: Standard hours: 7 p.m.-7 a.m. barred. Summer hours (Jun-Aug): 8 p.m.-6 a.m. barred. Downtown exception: Gulch/Hope Gardens: 8 p.m.-6 a.m. year-round. Enforcement: Dept. of Codes Administration. Exception process: Variance permit from codes director.

Working outside the permitted hours without a qualifying exemption or an approved variance is a code violation enforced by the Department of Codes Administration, which can cite the responsible party and order work stopped.

The Bottom Line

Nashville'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 Nashville is broadly strict or permissive.
