What is the acceptable level of noise in my area?

The Noise Program scientifically measures the level of noise in decibels based on the zone in which you live or work to determine if a source of noise violates the code. The table below shows the allowable decibel levels set by the zoning of where the noise is coming from (source zone), as it is heard and measured with a noise meter at a separate property where the noise is heard (receiver zone). 

We have decibel meters that can be loaned out to help you determine if a violation might exist. Please note, our meters are only to help determine a baseline sound so a Noise Inspector can follow up, if needed and require a deposit of $60. This meter loaning  program is currently on hold due to the pandemic.

**We cannot discuss sound readings taken with cell phones apps or multi-meters as their level of accuracy is not reliable.**

Noises Addressed by Noise Program

The Noise Program’s primary focus is to address and educate the public on the following types of noise disturbances within Portland city limits:

  • Amplified sounds (speech, music, events, parades)
  • Commercial and industrial operations
  • Residential HVAC equipment
  • Motor vehicles (in rare cases)
  • Home equipment and powered tools
  • Leaf blowers
  • Construction and construction equipment

If you believe that there is a possible noise violation and wish to report it to our office, please only report the incident and location once. Duplicate reports will only slow down the process.

If you are submitting a complaint about construction work on a city street, please indicate if the work is being done by Portland Bureau of Transportation, Bureau of Environmental Services, or the Portland Water Bureau. If the construction work is being done by any of these City of Portland bureaus, please check their website first for detailed information about the project before contacting our office.

For a single event such as a neighbor’s loud party, we recommend you talk directly with your neighbors about the issue before contacting our office.

Once a case is opened, the complainant will receive an email from the Noise Office with the case number and next steps. If the warning letter does not resolve the issue after two weeks, the complainant should email the Noise Office directly with the recent dates and time frames of incident they reported. A follow-up email is far more helpful than continuously submitting an online complaint.

What to do if you believe noise is violating The City of Portland’s Noise Code

For most neighbor-to-neighbor noise concerns, the very first place to begin is to reach out to your neighbor. Many times, issues can be resolved by working together. Check out these resources from Civic Life on how to have safe and constructive conversations:

  • Contact Civic Life’s Community Safety Program at (503) 823-4064 to set up a free Neighbors Together training for you and your neighbors!
  • Civic Life's Constructing Civic Dialogues provides no-cost training on communication and conflict resolution to the public. Learn more about upcoming trainings here.

The Noise Program has decibel meters that can be loaned out to help determine if a violation might exist (the loaner program is temporary suspended due to the pandemic). Our meters only help to determine a baseline sound so a noise inspector can follow up, if needed. We cannot discuss sound readings taken with cell phones apps or multi-meters as their level of accuracy is not reliable.

Submit a Noise Complaint

If your complaint falls within the Noise Program’s primary focus criteria (see above list), you can fill out an online complaint form. When the program receives a complaint, it will be reviewed to see if it qualifies as a Noise Code violation. If it does not, the case will be closed. If it does, the Noise Program will issue a warning letter to the source of the noise. If that does not resolve the issue, a noise control officer will make direct contact with the source of the noise to try and resolve it and may possibly issue a citation.

For more information, contact the Noise Program at 503-823-7350 or noise@portlandoregon.govduring regular business hours (8:00 am to 5:00 pm). If you are reporting noise currently in progress after 10:00 pm, please contact the Police non-emergency line at 503-823-3333.
