• Getting Started

    A building permit is required for alterations in commercial and multifamily buildings, even when no structural changes are made.

    If your project includes increasing the footprint of the structure or altering any exterior feature beyond same size replacement of doors and windows, view commercial new construction.
     
    Change of Use or Occupancy
    For an overview of requirements for projects that change the use of a space or building, see our Change of Occupancy Brochure and Change of Use or Occupancy information page. Depending on the complexity of the project, 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. Visit Plan Review staff at the Development Services Center or call (503) 823-1456 for life-safety summary information.
     
    If your project includes work that would change the occupancy or use of an existing building, visit Building staff and Planning and Zoning staff at the Development Services Center before you prepare your materials and plans.
     
    See State Codes information for the current building codes in effect. Depending on the scope of work, your project may also require electrical, plumbing and mechanical permits.
     
    Alterations to unreinforced masonry buildings may trigger additional seismic strengthening.

    Determine what the system development charges will be for your project.

    Early Assistance:
    The bureau offers four early assistance levels for commercial customers.

    The City also recognizes that some projects need special assistance due to the complexity of the project. These projects may be assigned a City development liaison to assist the developer and the development team through all phases of the project from early assistance, city review, construction and final occupancy. Visit staff at the Development Services Center to discuss whether a development liaison is appropriate for your project.

    Applying For My Permit

    The following information must be submitted when applying for a permit for a commercial alteration/tenant improvement. Since every project is unique, there may be some situations where you will be asked to provide additional information.

     

    APPLICATION

    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.

    Plan Review Process

    Some simple Commercial Alteration permits can be issued "over the counter" while you wait. You will meet with review staff from different departments who will check your construction documents to verify the proposed construction will meet the various codes. During the review, if information is missing, or if corrections are needed, you will be asked to return with that information.

    If the project is more complex and a review cannot be completed over the counter, 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 flowchart.

    The bureaus/review groups that will check a commercial alteration project include:


    Inspections

    The yellow 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, if there is any ground disturbing activity, then erosion control measures must be installed, inspected and approved, prior to beginning any other work.
