AI Executive Summary
Portland, OR has the oldest comprehensive Noise Code in the United States, established in 1975 and originally funded by the EPA and HUD as a national model for cities and towns across America. The code (Portland City Code Title 18) covers a broad range of noise sources across residential, commercial, and industrial zones, with quiet hours from 10 PM to 7 AM. Enforcement is managed by the Noise Control Program within Portland Permitting & Development. Portland is also unique in having a Noise Review Board — a quasi-judicial body that hears appeals and contested cases related to noise violations.
Specific Noise Restrictions
Construction
Construction noise is prohibited before 7 AM and after 6 PM on all days, and all day on Sundays and six legal holidays. Noise exceeding 60 dBA at the lot line is also prohibited during permitted hours. Commercial construction equipment and commercial transport vehicles are exempt from general quiet hours if not plainly audible in a dwelling unit.
Amplified Sound
It is unlawful to cause or permit any noise disturbance. Sounds plainly audible in any dwelling unit between 10 PM and 7 AM are prohibited. Amplified sound outdoors is subject to decibel limits by zone and may require a permit for public events.

Noise Review Board
Portland operates a Noise Review Board — a quasi-judicial body unique among U.S. cities — that hears appeals of noise violation decisions and contested enforcement cases. Residents and businesses can appeal enforcement actions before the board, which has authority to modify, reverse, or uphold penalties. This body has been a key part of Portland's noise governance since the code's founding in 1975.
Industrial & Mechanical Equipment
Heating, ventilation, air conditioning (HVAC), refrigeration, and other mechanical equipment must comply with property-line decibel limits by zone.
