Construction Noise and Regulations
City of Portland regulations on construction noise. (Code section 18.10.060)
Permissible Hours and Noise Levels -- From 7 a.m. to 6 p.m. Monday through Saturday, the City permits a very liberal standard for construction noise (85 dBA at a 50' distance). This means that, provided your equipment is in good repair and muffled (if possible), it will be compliant. The few kinds of equipment that cannot meet this level – (for example: jack hammers, concrete saws, and pile drivers) are exempt from the standard during the daytime period.
Outside Permissible Hours -- Outside permissible hours, different rules apply. First, the exemptions for jackhammers and other noisy equipment do not extend to other hours. Also, most importantly, work at other hours must meet the "baseline permitted decibel levels" of the area in which the work is taking place. Experience has shown that although you will probably have no problems with work in an industrial zone, you will likely be in violation of the code for exterior work (e.g., clearing, grading, excavating, framing, roofing, etc.) in a residential zone or near residential use before 7 a.m., after 6 p.m., or on Sundays, or holidays.
Complaints -- When complaints are received, it is usually because of the hours of operation rather than the noise. The 7 a.m. start time includes noise generated by warm-up and maintenance. If we receive a complaint, we will contact you, and request that you take care of it. Most complaints stop here.
Possible Citations -- If additional legitimate complaints are received, be aware that each individual or organization responsible can receive a citation and fine of $5,000 for each violation. If needed, a court-ordered “stop work” order can also be obtained.
Noise Variances -- There are times when work must occur outside of the permissible hours and you may apply for a noise variance. Construction noise variances may be issued if the need is valid and livability impacts are minimized. Accelerated review fees will be required for applications submitted fewer than ten business days prior to the event.
Ensure to submit your noise variance application on time: Submission must be at least 4 business days before activity.
Long term construction projects usually are required to present their application before the Noise Review Board. Completed applications to be reviewed by the Noise Review Board must be submitted 45 business days prior to the Noise Review Board meeting.
Noise regulations do not apply for emergency work "…necessary to restore property to a safe condition following a public calamity, work to restore public utilities, or work required to protect persons or property from imminent exposure to danger."
