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.
- Completed Building permit application
- Completed Commercial system development charge form
- Four copies of architectural plans and supporting documents for the proposed Alteration and the areas affected by such work as indicated in the Submittal Guidelines listed below:
- For Major Commercial Alterations, which includes projects with a valuation of $145,200 or more, with only minor changes to the exterior, please refer to the Major Commercial Alterations Submittal Guidelines.
- For Minor Commercial Alterations, which includes projects with a valuation of less than $145,200, and only minor changes to the exterior, please refer to the Minor Commercial Alterations Submittal Guidelines.
To submit for a permit, bring the completed building permit application and commercial system development charge form, required plans, additional materials and intake fees to the 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.
THINGS TO CONSIDER:
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.
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.
