Overview of Philadelphia's Noise Ordinance
Philadelphia regulates noise through Chapter 10-400 of the city code, which covers excessive noise and sounds. The ordinance applies to all noise sources including construction, commercial operations, entertainment venues, motor vehicles, and residential activities.
Unlike some cities that set specific decibel limits, Philadelphia's code largely uses a "plainly audible" standard — meaning sound that can be heard across a property boundary is potentially in violation. This makes documentation critical if you're filing a complaint.
Key Noise Limits and Rules
Residential Noise
No person may make unreasonable noise that disturbs the comfort or repose of others. During quiet hours (9 PM - 8 AM), the standard is stricter — any noise plainly audible beyond the property line of the source may be a violation.
Common violations include loud music, barking dogs, loud parties, and amplified sound systems. Air conditioning units and other mechanical equipment must comply with noise standards when operating near residential boundaries.
Construction Noise
Construction is permitted between 7:00 AM and 8:00 PM on weekdays. Work outside these hours requires a special permit from Licenses & Inspections (L&I). Emergency repairs are exempt.
Construction noise typically ranges from 80-110 dB. Use our free decibel meter to document noise levels from nearby construction sites.
Commercial and Entertainment
Bars, restaurants, and entertainment venues must keep noise levels from disturbing nearby residents. The city can impose conditions on entertainment licenses, including sound level limits and required sound insulation.
Outdoor amplified music events require permits and must comply with specific noise limits set by the managing agency.
Motor Vehicle Noise
Excessive vehicle noise from modified exhausts, stereo systems audible at 75+ feet, and unnecessary horn honking are prohibited. Philadelphia police can issue citations for excessively loud vehicles under both city code and state motor vehicle regulations.
How to Measure and Document Noise Violations
If you're dealing with ongoing noise issues, documenting the problem strengthens your complaint. Here's how to build a case:
Measure the sound level
Use our free online decibel meter to record noise levels from inside your home. Readings above 70 dB indoors typically indicate excessive outside noise.
Export your readings
DecibelPro lets you export CSV reports with timestamped readings, peak levels, and averages. This creates a paper trail for your complaint.
Keep a noise log
Record dates, times, duration, and type of noise. Note how the noise affects your daily activities. This pattern of disturbance is important for enforcement.
Record audio/video evidence
If safe and legal to do so, record the noise from your property. Video showing the time of day and audibility adds weight to complaints.
How to File a Noise Complaint in Philadelphia
Option 1: Call 311
Dial 311 from any phone in Philadelphia. The non-emergency line operates 24/7. Describe the noise issue, provide the exact address, and note how long it has been going on. You'll receive a service request number for tracking.
Option 2: Philly311 App or Website
Submit a complaint through the Philly311 mobile app or website. You can attach photos and descriptions, pin the location on a map, and track the status of your complaint online.
For Emergencies: Call 911
If the noise is associated with dangerous activity, violence, or an immediate threat to safety, call 911 instead of 311.
Penalties for Noise Violations
Philadelphia can impose fines for noise code violations. First offenses typically result in a warning or a fine of $150-$300. Repeat violations can escalate to $300-$2,000 per offense. Chronic violators may face daily fines and potential license revocation for commercial establishments.
For construction noise violations, L&I can issue stop-work orders and fines. Venues can have their entertainment permits suspended or revoked for repeated noise violations.
