Important things to know about commercial permits
A building permit is required to construct a new commercial structure or multi-family residential project with three or more units and to add to, repair, alter, or change occupancy of existing structures.
Before you apply for a permit, research the following items:
- the zoning of the property
- the applicable codes
- existing permits on site
- occupancy of the existing building
- the permit cost
- SDC charges
- feasibility of the project
- time a permit remains active
Codes in effect in Portland include City Codes, such as Titles 24 and 33, as well as State building codes. See our Codes page for more information.
Find out how to research your property and where to locate the information in preparation for your permit application.
Determine what your fees will be.
Determine what the system development charges will be for your project.
For projects with complicated building or fire code issues you may need some assistance. Customers may request a preliminary Life Safety meeting. Review the Life Safety Preliminary Meeting Request Packet for information.
Land use Early Assistance requests help applicants prepare a complete project proposal, usually a land use review application. A Land Use Pre-Application Conference is required for all Type III and IV land use reviews prior to submittal of the application. They are also available but optional for lower tier Land use reviews.
Applications must show how they meet the building code with a code summary. The building code summary is critical to convey design assumptions made for the building.
Change of Occupancy
Projects that change the occupancy or use of the existing space can be very complex. The Change of Use or Occupancy brochure has information on this type of project.
Fire Life Safety Summary
For very complex projects, the Fire Life Safety Summary may be needed. This summary form has more detail about sprinkler, fire alarms, detection systems and other construction information about the building.
If your project contains space that will not be built out and ready for occupancy at the time the permit is finalized, a separate Tenant Improvement permit will be necessary to establish 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.
What you need for a commercial new construction or addition building permit (submittal standards)
As part of the review process, a complete submittal is required which includes a completed building permit application, life safety completeness checklist for commercial permits, a Shell TI Acknowledgement statement, architectural, structural, electrical, mechanical, plumbing and landscape drawings.
Your project will most likely need separate electrical, plumbing and mechanical permits. These permits are applied for separately once the project has been approved for issuance.
Review the drawings requirements:
- Drawings, drawn to scale where necessary to verify compliance with code.
- Drawings may be handwritten/drawn if clear and legible. Text or note shall be in print.
- Minimum drawing size: 11x17. All required information is to be clear and legible. Minimum printed text is to be 3/32” or the equivalent 12-point font.
- Cannot use professional's drawings without the permission of the professional who signed the original drawings. For example, an architect’s stamped plan set cannot be used without their permission.
Prepare the following information:
- Building permit application
- Erosion control plan. Install erosion control measures before beginning any further ground disturbing activities. These measures must have an approved inspection.
- Life Safety Completeness Checklist for Commercial Permits
- Commercial system development charge form
- Simplified approach form and/or stormwater plan
- Review the submittal standards and drawing criteria listed in this handout: Submittal Requirements Commercial - New Construction, Additions, Alterations with Exterior Work or Structural Changes
- Complete a Shell Permit Acknowledgement Statement if your project includes space that defers occupancy to a future tenant improvement permit
How to submit your building permit application and plans
Schedule an a Building Permit Intake Appointment.
Smaller projects are submitted through the Single PDF process.
Larger projects are submitted through PDX E-plans using ProjectDox.
Plan review process
After you pay intake fees, your project will be "under review". The plans will be taken in for further review. You will be sent a checksheet requesting any clarifications or corrections. For additional information on the review process, see the permitting process overview.
The bureaus/review groups that commonly check this type of project are:
- Planning and Zoning review
- Life safety review
- Structural review
- Site Development review
- Bureau of Fire and Rescue
- Bureau of Environmental Services review
- Portland Bureau of Transportation review
- Bureau of Parks and Recreation review
- Urban Forestry review
- Water Bureau review
Every project is unique and additional information may be required for review. If additional information is required to verify the work meets state and/or city requirements, a checksheet requesting any clarifications or corrections will be issued to the applicant identified on the permit application.
Permit status can be reviewed on Portland Maps permit/case search. All first reviews must be complete before you can submit checksheet corrections. Before contacting Permitting Services to schedule an appointment to submit your checksheet corrections, please look your permit up on Portland Maps to ensure all reviews are complete.
When the last technical review is approved, your permit will be pre-issued. Pre-issuance is the last permit check. This step ensures all required reviews took place, all required approval stamps are on the plans, and the fees are charged correctly. The applicant listed on the building permit will be contacted when the permit is ready. Staff will provide instructions on how to obtain the approved permit and pay the final fees. The permit is not issued until all fees are paid.
Get ready for inspections
The inspection card lists all the inspections you will likely need during your construction project, and what work needs to be done first.
Once your building permit is issued, erosion control measures and sometimes tree protection measures must be installed, inspected and approved prior to beginning any further ground-disturbing activities.
All permits need a final approval inspection to be complete.
Commercial inspections, results and corrections
To schedule an inspection, call the automated inspection request line. You will need your IVR or permit number and the three digit code for the inspection. You must call before 6:00 a.m. or the inspection will be scheduled the following business day.
Get the results of the inspection on Portland Maps permit/case search the next day.
Not approved - there are some reasons why the work did not get approved:
- no access - the inspector may not have been able to inspect the work
- incomplete work
- code violations
The inspector will list the corrections needed on the inspection report. Call for a reinspection after making the corrections. Use the same three digit inspection code.
If you make the corrections the same day, wait until 5:00 p.m. to request a reinspection. The inspector needs to enter their results before you can schedule the reinspection. There is a reinspection fee charged for more than one reinspection for a single issue.
Contact commercial inspectors
If you have questions before your inspection, you can talk to an inspector. The commercial inspector area map lists the inspector's name, area, and phone number.
Because of vacation or illness, your inspector may be different than the one listed on the map. If you have questions after your inspection, find out which inspector to call. Their contact information will be on the inspection results and on Portland maps.
