The Portland Noise Office is the City of Portland’s Bureau of Development Services (BDS) program that enforces the city’s noise control code. It handles complaints about excessive noise from construction, industrial activity, and other sources regulated under Portland City Code Chapter 18.02.
Background: Why Portland Has a Noise Office
Portland’s noise code was adopted in the 1970s to balance the needs of a growing city with residents’ right to quiet. The code sets specific decibel limits for different times of day and land use zones, and it gives the Noise Office authority to investigate complaints, issue citations, and require corrective action. The office operates within BDS, which also manages building permits and inspections—so noise enforcement is tied to the city’s broader regulatory framework.
The office’s primary focus is on stationary sources: construction sites, HVAC systems, industrial equipment, and commercial operations. It does not typically handle neighbor-to-neighbor noise like loud parties or barking dogs—those fall under other city bureaus or the police.
How the Portland Noise Office Works
When someone files a complaint, the Noise Office follows a standard process:
- Complaint intake: Complaints can be submitted online, by phone, or via the city’s 311 system. The office asks for the address, time of day, and description of the noise.
- Investigation: A noise inspector may visit the site to measure sound levels with a decibel meter. They also check whether the source is operating within permitted hours.
- Enforcement: If a violation exists, the office can issue a warning, a citation with a fine, or a stop-work order—depending on severity and history.
- Follow-up: The complainant is notified of the outcome, and the office may monitor the site for repeat violations.
The office’s authority is limited to code violations. It cannot mediate disputes or force private parties to negotiate.
Noise Limits and Permitted Hours
Portland’s noise code sets maximum sound levels measured in A-weighted decibels (dBA) at the property line of the noise source. The limits vary by zone and time of day:
- Residential zones: 55 dBA during the day (7 a.m.–10 p.m.) and 50 dBA at night.
- Commercial zones: 60 dBA during the day and 55 dBA at night.
- Industrial zones: 75 dBA at all times, with some exceptions.
Construction is generally allowed between 7 a.m. and 6 p.m. on weekdays and 8 a.m. to 5 p.m. on Saturdays. Work is not permitted on Sundays or major holidays without a special permit. The Noise Office can grant after-hours permits for emergencies or essential services.
Common Problems and Misconceptions
One frequent misconception is that the Noise Office can immediately stop any loud noise. In reality, the process takes time—an inspector must first verify the violation, which may require multiple visits. Another issue is that many people call about noise that isn’t actually covered by the code, such as:
- Traffic noise from public streets
- Airplane or train noise (federal jurisdiction)
- Voices or music from neighbors (handled by police as disturbance)
Also, the code’s decibel limits are not absolute—they allow for “reasonable” noise in context. For example, a construction site that briefly exceeds the limit during a concrete pour may not be cited if it’s within permitted hours and the excess is minimal.
How to File a Complaint
If you need to report a noise issue, here’s what to do:
- Note the date, time, and duration of the noise.
- Identify the source address and the type of activity (construction, industrial, etc.).
- Call the city’s 311 line or submit an online form through the BDS website.
- Provide your contact information if you want a follow-up (anonymous complaints are accepted but harder to investigate).
For urgent safety issues—like a gas leak or imminent hazard—call 911 instead. The Noise Office does not handle emergencies.
Alternatives and Related Resources
If your complaint isn’t about a stationary source, you have other options:
- Neighbor noise (parties, loud music): Contact the Portland Police Bureau non-emergency line.
- Barking dogs: Multnomah County Animal Services handles animal noise.
- Construction before 7 a.m.: Still a Noise Office issue, but you can also report it to the BDS building inspector if it’s an active site.
For chronic problems, you can also attend a neighborhood association meeting or contact your city commissioner’s office to advocate for code changes.

Frequently Asked Questions
What hours can construction make noise in Portland?
Construction noise is allowed from 7 a.m. to 6 p.m. on weekdays and 8 a.m. to 5 p.m. on Saturdays. It is prohibited on Sundays and major holidays unless the contractor has a special permit from the Noise Office.
Can I get a noise complaint dismissed if I’m within the decibel limit?
Yes. If a noise inspector measures your activity and it is below the applicable limit for your zone and time of day, the complaint will be closed without a citation. However, the code also prohibits “unreasonable” noise, so even a low-decibel sound could be a violation if it’s persistent and disruptive.
How long does the Noise Office take to respond?
Response times vary. The office prioritizes complaints about after-hours construction and industrial noise. In most cases, an inspector will visit within a few business days. For ongoing issues, you can submit multiple complaints to document a pattern.
Does the Noise Office handle noise from bars or restaurants?
Yes, but only if the noise comes from mechanical equipment like HVAC units or exhaust fans. Live music or patron noise is typically handled by the police or the OLCC (Oregon Liquor and Cannabis Commission) as a public disturbance.
What are the fines for violating Portland’s noise code?
Fines start at $100 for a first offense and can go up to $1,000 or more for repeat violations. The Noise Office may also issue a stop-work order for construction sites that repeatedly violate the code, which can cost contractors far more in delays.
