Philadelphia noise rules: limits, barking dogs and how to complain

Philadelphia’s noise law is Chapter 10-400 of the Philadelphia Code, “Noise and Excessive Vibration.” Unlike many cities, it does not switch on at 10 p.m. The limits for noise from a home apply around the clock, and they are tight.

Noise from homes and apartments

Section 10-403(2) bars sound from a residential property that is either:

• audible more than 100 feet from the property boundary, or
• more than 3 decibels above the background level, measured beyond the property boundary.

For apartments and other multi-unit buildings, the “property boundary” is the legal property line plus any partition between separately occupied units (§ 10-402(9)). So in a rowhouse split into apartments, sound coming through the shared wall at more than 3 dB above background is covered. “Background sound level” means the normal sound in the area without the source in question (§ 10-402(1)).

The residential rule has exceptions in § 10-403(2):

• Lawn equipment between 8 a.m. and 8 p.m., if it is working properly and has its muffler
• Air conditioners and refrigeration units, which instead may not exceed 5 dB above background at the nearest occupied home, or 10 dB above at a non-residential property
• Animals, which have their own rule (below)
• The unamplified human voice

That last exception is worth knowing. Loud talking or shouting without a speaker is not covered by the residential decibel rule. Amplified music is.

Barking dogs

Section 10-403(6) is unusually specific. No one may allow more than 5 sounds from one or more animals (the code’s example is individual barks) within a five-minute period if they can be heard more than 50 feet from the property boundary. Zoos, vet clinics, shelters and similar facilities are exempt.

If you are keeping a log, count barks over five-minute stretches. That is the measure the code uses.

Businesses and bars

Sound from a non-residential property may not exceed 5 dB above background at the nearest occupied home, or 10 dB above background at a non-residential property (§ 10-403(3)). Concert venues and stadiums are capped at 70 decibels at the nearest occupied home (§ 10-403(5)).

Street noise and other rules

• Amplified sound from a radio or similar device in the public right-of-way next to a residential property is banned from 9 p.m. to 8 a.m. unless the person uses earphones (§ 10-403(7)).
• Home and car alarms may not sound for more than 15 minutes (§ 10-403(10)).
• Consumer fireworks are barred after 9 p.m. except as the Fire Code allows (§ 10-403(12)).
• Vehicle noise may not be more than 5 dB above background measured from 25 feet (§ 10-403(14)).

Construction

Section 10-403(8) exempts regular construction from most of the decibel rules, as long as equipment is maintained and operated legally. The city’s Air Management Services page says construction noise affecting homes should be no more than 5 decibels above background from 8 p.m. to 7 a.m. on weekdays and 8 p.m. to 8 a.m. on weekends, with exceptions for emergencies and public works.

Who to contact

The City of Philadelphia says to report noise from individuals or residential sources by calling 911 or contacting your local police district. The Philadelphia Police list 311 as their non-emergency number. For a problem that keeps coming back, the police department has a Neighborhood Concern (Roll Call Complaint) form.

Noise from commercial and industrial sources goes to Air Management Services: (215) 685-7580 or [email protected]. The city says those complaints are investigated the same day.

Under § 10-404, the Department of Public Health, the Police Department and the Department of Licenses and Inspections can all enforce the chapter.

Penalties

Fines under § 10-406 rise with repeat violations within twelve months:

• First violation: $100 to $300
• Second: $200 to $400
• Third: $300 to $500
• Fourth or later: $500 to $700

Each day a violation continues counts as a separate violation.

Keeping a record

A 3 dB margin is small, which makes a running record more useful than a single complaint. The Noisy Neighbor iPhone app logs each incident with the time, duration and estimated average and peak levels, and you can add notes such as a bark count. It exports the log as a PDF report or a complaint letter for your landlord. The app’s readings are uncalibrated estimates, so they show the pattern; an official measurement still has to come from the city.
