How do I look up a permit for a property?

Most concerns that occur during construction are handled by the City’s building inspectors. You can use PortlandMaps to find the specific inspectors assigned to any permit. You can search by address and then click on the “Permits” tab under the Permits & Zoning heading. Click on the specific permit and scroll down to the “Activity” section. There will be a button with a number and an up/down arrow. Click on this button to expand the activity list. Scroll to the bottom of the list of see the inspections. If you scroll to the right of this list, it will tell you the name and phone number of the assigned inspector.

You can also call the general information line at 503-823-7300. Please describe your concern and the operator will direct your call accordingly.

I’m concerned that my neighbor’s construction will harm my tree. What can I do?

In many, but not all, situations, tree protection is required during construction. In most cases, the city can only require protection for trees that are on the site where the construction is happening. The city does not have the authority to force applicants to protect trees whose trunks are not at least partially on the site where the construction is happening. If you think construction may impact a tree which is shared with the property where the construction is occurring, please call the planner who reviewed the building permit. You can use PortlandMaps (general guide in PDF) to find the name and phone number of the planner or call the Zoning Hotline at 503-823-7526. Please note that it takes 1 to 2 business days to receive a call back from the zoning information line. 

If the tree is outside the construction site, the issue is a civil matter that must be resolved between yourself and your neighbor. The City’s Office of Community & Civic Life has resources for helping neighbors resolve conflicts through their neighborhood mediation program.
