Philadelphia noise ordinance: quiet hours, limits and complaints

Last updated: August 11, 2026

Quiet hours in Philadelphia

Philadelphia's noise chapter does NOT set a general city-wide quiet-hours window such as 10 p.m. to 7 a.m. The decibel limits in § 10-403 apply around the clock, so a violation at 2 p.m. is measured the same way as one at 2 a.m. The time-of-day rules that do exist are source-specific. Construction is the main one: § 10-402(11) defines "Regular Construction" as work between 7 a.m. and 8 p.m. Monday through Friday, or between 8 a.m. and 8 p.m. on weekends and legal, national or state holidays, and § 10-403(8) exempts only regular construction (plus emergency and public works construction) from the decibel limits. Outside those hours the exemption falls away and construction must meet the ordinary limits, which the City's own guidance describes as no more than five decibels above the background sound level from 8 p.m. to 7 a.m. on weekdays and 8 p.m. to 8 a.m. on weekends. The other timed rules: amplified radios or similar devices in the public right-of-way abutting a residential property are barred from 9 p.m. to 8 a.m. (§ 10-403(7)(a)); consumer fireworks are barred after 9 p.m. (§ 10-403(12)); lawn maintenance equipment is only exempt from the residential limit between 8 a.m. and 8 p.m. (§ 10-403(2)(a)); and the Board of Health's Noise and Excessive Vibration Regulations, Section II.A, bar ash, trash or garbage collection that creates noise at residential sites between 9 P.M. and 7 A.M. without prior written permission of the Department.

Decibel limits

The limits are relative to the "background sound level," defined in § 10-402(1) as the measured sound level in the area, exclusive of extraneous sounds and the sound contribution of the source in question. They do not vary by zoning district; they vary by the type of property the sound comes from and the type of property it reaches. Residential source: not more than 3 dB above background measured beyond the property boundary, and not audible more than 100 feet from the property boundary (§ 10-403(2)). Non-residential source: not more than 5 dB above background at the property boundary of the nearest occupied residential property, or 10 dB above background at the nearest occupied non-residential property (§ 10-403(3)). Near a hospital, nursing home, house of worship, courthouse, school, library or day care facility: 3 dB above background at that facility's property boundary, and this stricter figure overrides any looser limit elsewhere in the chapter (§ 10-403(1)). Air conditioning and refrigeration units are carved out of the 3 dB residential rule and instead get 5 dB above background at the nearest residential boundary and 10 dB at the nearest non-residential boundary (§ 10-403(2)(b)). Concert venues (seating capacity more than 1,000, per § 10-402(3.1)) and stadiums have the one absolute limit in the chapter: 70 decibels measured at the property boundary of the nearest occupied residential property (§ 10-403(5)). Motor vehicles: 5 dB above background measured from 25 or more feet (§ 10-403(14)). Sirens may not exceed 128 decibels more than 10 feet from the source (§ 10-403(10)(a)), and burglar/vehicle alarms must shut off within 15 minutes (§ 10-403(10)(b)). Vibration may not exceed 0.15 inches per second beyond any property boundary or 30 yards from a moving source (§ 10-403(11)). Two limits are audibility-based rather than metered: sound from a special assembly occupancy audible more than 100 feet from its property boundary (§ 10-403(4)), and more than 5 animal sounds in a five-minute period audible more than 50 feet from the property boundary (§ 10-403(6)).

What the ordinance actually says

§ 10-403(2): "Sound From Residential Properties. No person shall create or cause, or permit the creation of, sound originating from a residential property audible at a distance greater than one hundred feet from the property boundary or that exceeds 3 decibels above background level measured beyond the property boundary except for the following:"

§ 10-403(3): "Sound From Non-Residential Properties. No person shall create or cause, or permit the creation of, sound originating from a property used for a non-residential purpose that exceeds: (a) 5 decibels above background level measured at the property boundary of the nearest occupied residential property; or (b) 10 decibels above background level measured at the property boundary of the nearest occupied non- residential property."

§ 10-403(1): "Sound Near Protected Facilities. No person shall create or cause, or permit the creation of, sound that exceeds 3 decibels above background level measured at the property boundary of any hospital, nursing home, house of worship, courthouse, school, library or day care facility. This provision shall apply, notwithstanding the potential applicability of a less restrictive standard in this Chapter."

§ 10-402(11): "Regular Construction. Construction between the hours of 7 a.m. and 8 p.m., Monday through Friday, or between the hours of 8 a.m. and 8 p.m. on weekends and legal, national or state holidays."

§ 10-403(8): "Exception for Construction Activity. The restrictions of subsections (1) through (5) and (7)(b) do not apply to regular construction and emergency and public works construction, provided that all equipment used in connection with such construction is maintained and operated in compliance with all applicable law."

§ 10-403(7)(a): "abutting a residential property by amplification from a radio, tape player or similar device between the hours of 9 p.m. and 8 a.m., unless used in connection with an earplug or earphones which will prevent significant emanation of sound from such device; or"

§ 10-403(5): "Sound From Concert Venues and Stadia. No person shall create or cause, or permit the creation of, sound originating from a concert venue or stadium that contributes to a total sound level, exclusive of extraneous sounds, that exceeds 70 decibels measured at the property boundary of the nearest occupied residential property."

§ 10-403(6): "Animal Sounds. No person shall cause or permit more than 5 expressions of sound from one or more animals (such as individual barks from one or more dogs) during a five minute period from any property audible at a distance greater than 50 feet from the property boundary."

§ 10-403(14): "Sound Emanating From a Motor Vehicle. Notwithstanding anything to the contrary in subsection (7) (\"Sound Created in the Right-of-Way\"), no person shall create or cause, or permit the creation of, sound emanating from a motor vehicle, at a level of five decibels above background level measured from a distance of 25 or more feet."

§ 10-402(1): "Background sound level. The measured sound level in the area, exclusive of extraneous sounds and the sound contribution of the specific source in question."

§ 10-402(9): "Property Boundary. In the case of a single-family dwelling, or a property used solely for non-residential purposes, the legal property line. In the case of a structure containing two-family, multi-family or other non-single- family residential dwellings, the legal property line and any partition between separately occupied units within the property."

§ 10-403(11): "Excessive Vibration. No person shall create or cause, or permit the creation of, vibration levels that exceed 0.15 inches per second beyond any property boundary or 30 yards from any moving source."

§ 10-405(1): "The Department shall investigate complaints about noise or excessive vibration, make observations and maintain surveillance of the discharge or escape of noise or excessive vibration. The names and addresses of complainants shall be kept confidential by the Department."

§ 10-406(1): "The penalty for an initial violation of this Chapter is a fine of not less than one hundred dollars ($100) and not more than three hundred dollars ($300)."

How to file a noise complaint in Philadelphia

Two separate routes, and picking the wrong one wastes your call. For commercial and industrial noise, including construction sites, bars, clubs, restaurants, rooftop HVAC and stadium noise, contact the Philadelphia Department of Public Health's Air Management Services complaint line at (215) 685-7580 or email dphams_service_requests@phila.gov; the City's page states that complaints are investigated the same day they are received. For noise from individuals or residential sources, such as a neighbour's party, stereo or barking dog, the City directs residents to call 911 or contact their local police district rather than Air Management Services. Philly311 (dial 311 inside the city, or (215) 686-8686) can route a request if you are unsure which applies. § 10-405(1) requires the Department to keep the complainant's name and address confidential.

For the general playbook — documenting the problem, talking to a landlord or HOA, when 311 beats 911 — see the noise complaints guide.

Worth knowing

Relative, not absolute. The headline rule is that almost every limit is stated as decibels above the background sound level, not as a fixed dB ceiling. That means a violation depends on how quiet the block already is: the same stereo can be legal on a busy avenue and illegal on a quiet residential street. The only fixed numbers in the chapter are 70 dB for concert venues and stadiums, 128 dB for sirens, and the vibration figure. Anyone quoting "Philadelphia's noise limit is X dB" as a flat number is wrong. Party-wall rule. § 10-402(9) defines "Property Boundary" for a two-family, multi-family or other non-single-family residential building to include "any partition between separately occupied units within the property," so the 3 dB-above-background residential limit is enforceable through a shared wall between apartments, not just at the street-facing lot line. Construction is exempt only during its window. § 10-403(8) does not give construction a looser limit; it removes the limits of subsections (1) through (5) and (7)(b) entirely during "Regular Construction" hours and for emergency and public works construction. Step outside 7 a.m.-8 p.m. weekdays or 8 a.m.-8 p.m. weekends and holidays and the ordinary 5 dB-above-background residential limit snaps back into force. Unamplified human voice is exempt from the residential limit (§ 10-403(2)(d)), so shouting neighbours are not a Chapter 10-400 matter. Animals get their own count-based test instead of a dB test. Automated vehicle-noise enforcement. Bill No. 210870 (passed by Council June 23, 2022, signed by the Mayor September 13, 2022) added both the 5 dB motor-vehicle rule and § 10-412, authorising an "Automated Vehicle-Noise Enforcement System" of stationary cameras and decibel meters, administered like a parking violation through the Philadelphia Parking Authority, with the registered owner liable regardless of who was driving unless the vehicle was reported stolen and unrecovered. Permits and carve-outs. Permitted demonstrations on City property are exempt from the right-of-way rules under § 10-403(7)(c), but the Board of Health's Noise and Excessive Vibration Regulations, Section II.B, then impose 10/5/3 dB-above-background caps on amplification at those permitted demonstrations. § 10-403(13) exempts aircraft, airport and railroad operations, licensed fireworks displays, religious bells and chimes lasting no more than 5 minutes in any one hour, school bells, clock and bell towers, and consumer fireworks on federal holidays. The consumer-fireworks subsection cross-references the Fire Code rather than setting its own standard, which is where Pennsylvania's state fireworks law flows through. Enforcement is split in practice. § 10-404(1) gives enforcement power to three bodies at once: the Department of Public Health, the Police Department and the Department of Licenses and Inspections. In practice the City routes commercial and industrial noise to the Health Department's Air Management Services and noise from individuals and residences to the police. § 10-405(1) provides that the Department shall keep complainants' names and addresses confidential. Fines escalate from $100-$300 for a first violation to $500-$700 for a fourth within twelve months, and each day a violation continues counts as a separate violation (§ 10-406).

Document it before you report it

Philadelphia's limits are measured numbers, so a reading is direct evidence of how loud it really is. 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 Philadelphia noise map. For time-stamped measurement history you can show a landlord or code officer, the app keeps a log.
