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 Shell Permit Acknowledgement Statement (if your project includes space that defers occupancy to a future tenant improvement permit)
- Completed Commercial system development charge form
- Four (4) copies of Site and Building construction drawings:
- See Submittal Standards and drawing criteria listed in handout Commercial – New Construction, Additions, Alterations with Exterior Work, or Structural Changes
- Erosion control plan. Note: erosion control measures must be installed, inspected and approved, prior to beginning any further ground disturbing activities.
- Mitigation form and/or a stormwater plan
To submit for a permit, bring these forms, and four (4) copies of the required plans, additional materials and intake fees to the Development Services Center.
The General Contractor must be identified prior to the building permit issuance.
Depending on the scope of work, your project will most likely require separate electrical, plumbing and mechanical permits. These permits must be obtained by the sub-contractors prior to performing the work. Sub-contractors you hire 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 contains space that will not be built out and ready for occupancy at the time the permit is finaled, a separate Tenant Improvement permit will be necessary in order to obtain first occupancy of the space. Since changes between the first Shell permit and the subsequent TI permit are common, a signed Shell Permit Acknowledgement Statement is required.
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.
