Applying For My Permit

The following information must be submitted when applying for this permit type. Since every project is unique, there may be some situations where you will be asked to provide additional information.

To submit for a permit, bring these forms, and (4) copies of the required plans, additional materials and intake fees tothe Development Services Center.

Separate Plumbing, Electrical, and Mechanical permits are required for alterations to those systems. Sub-contractors performing this work must be registered with the State of Oregon and carry a current CCB license.


Code Summary
Applications must show how they comply with the building code. A code summary is critical to convey design assumptions made for the building. Please see the Building Code Summary Worksheet

Change of Occupancy
Projects that change the occupancy of the existing space can be very complex. Please see both our Brochure on Change of Occupancy and additional information on this type of project.

Life Safety Summary
For very complex projects, a life-safety summary may be needed. This is similar to a code summary, but has more detail about sprinkler, fire alarms, detection systems and other construction information about the building. Please see the handout for Fire and Life Safety Summaries (FLSS) for more information.

Shell Permits
If your project is in a space that was originally permitted as a “Shell”, meaning it was not built out and ready for occupancy under the prior permit, your permit will be taken in and routed to the original reviewer. Under the Shell permit, the owner was required to complete the Shell Permit Acknowledgement Statement as part of that submittal.

Seismic Strengthening Requirements
Portland City Code, Title 24.85 contains criteria that may trigger requirements for additional seismic strengthening when the work involves an existing building.
