Quiet hours in Philadelphia, PA — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Philadelphia enforces residential quiet hours between 10:00 PM and 7:00 AM under Phila. Code §10-403. During this period, sound at any residential property line must not exceed 5 dBA above background ambient noise. Loud parties, amplified music, shouting, and similar disturbances are prohibited.
Philadelphia regulates noise under Title 10, Chapter 10-400 of the Philadelphia Code, primarily §10-403 (Sound Levels). The code establishes a background-plus-decibel standard rather than absolute limits: sound measured at the property line of any residential property may not exceed background ambient noise by more than 5 dBA between 10:00 PM and 7:00 AM, or 10 dBA at other times. Sound emanating onto public streets or other residential properties is also regulated.
Section 10-403(2) addresses specific nuisance noises including shouting, loud parties, barking dogs, and amplified music audible across property lines during quiet hours. The Philadelphia Department of Public Health, Air Management Services (AMS) division, enforces the noise code in coordination with the Philadelphia Police Department for live disturbances. Commercial establishments with amplified entertainment must comply with stricter standards under §10-403(3) and may need a special amplified-sound license.
Residents file complaints through Philly311 (dial 311 or use the Philly311 app). Police respond to active disturbances; AMS handles measurement-based and chronic-source complaints.
Violations of §10-403 carry fines of $150 to $300 per offense, with each day constituting a separate violation. Repeat violations may escalate to $700+ and Class III code enforcement action. Commercial establishments may face license suspension. Police can issue Code Violation Notices on scene.
