Portland is a growing, vibrant city that supports urban growth through construction projects and lively community celebrations. Sometimes events and building construction are expected to produce sound that is louder than our Noise Code allows. When this happens, the Noise Program may issue a noise variance to allow a project or event to exceed the City's Maximum Permissible Sound Levels ↗.
What is a noise variance?
A noise variance is an authorization or exception, granted exclusively by the Noise Control Officer or the Noise Review Board, that allows an individual, business, or organization to exceed the Maximum Permissible Sound Levels for a specific period or under certain conditions.
Do you need a noise variance?
You may need a noise variance if your activity will create noise that goes beyond what is normally allowed by the City’s Noise Code. City's Maximum Permissible Sound Levels ↗.
This includes activities like construction outside standard hours, amplified sound at events, live music, DJ or bands performances, or any loud activity that could disturb nearby homes or businesses.
If you're unsure whether your project or event requires a variance, it's best to review the Noise Code or contact the Noise Program for guidance before starting your activity.
