Applying For My Permit

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

Erosion control plan (may be a part of the site plan) or completed simple site erosion control form, if the project will result in ground disturbing activity. Note: Erosion control measures shall be installed, even when a simple site erosion control form has been accepted.

SITE PLAN (Scale site plans to most appropriate scale, e.g. 1”= 10’ or 1/4”= 1’)

  • Property lines, with dimensions
  • Adjacent streets and any easements
  • Property address and R number
  • North arrow
  • Structure to be demolished and its use
  • Distance between remaining buildings and between remaining buildings and property lines
To submit for a permit, bring the completed building permit application and four (4) copies of site, architectural, and structural plans (for the area of proposed work and areas affected by such work ) along with intake fees to the Development Services Center.

If you are hiring sub-contractors to do work on your project, and know who they are when applying, they will be listed on your permit at that time. If you don't know when you apply for your permit, they can be added after issuance. Sub-contractors you hire must be registered with the State of Oregon and carry a current CCB license.
  1. Demolition Delay Ordinance (Title 24.55.200)
    To preserve housing in the city, the Portland City Code under Title 24.55.200 requires that the issuance of a demolition permit (for some residential structures) be delayed for 35 days. The delay gives other parties, such as a neighborhood association, notification of the proposal, and time to take action, such as offering to buy or move the house. Demolition delay applies only to the demolition of residences in residential zones. When an application for a building permit for a replacement dwelling on the same site is applied for and paid for at the same time, the demolition delay can be waived.

    Demolition delay does not apply to:
    • The demolition of any building in a commercial zone
    • The demolition of any accessory structures (garages and sheds)
    • Buildings that are subject to demolition proceedings, i.e. a hearing order with the appropriate number listed
    • Buildings that have been declared a dangerous building (link to enforcement/dangerous buildings under enforcement services)
    • Historic landmarks
  2. Soil Compaction
    After demolition, the site must be restored to conditions suitable for new construction. If the building to be demolished has a basement or foundation that will result in a replacement fill of 24” or greater, the replacement soil is required to be compacted, and a soils special inspection by an independent agency is required.
  3. Utilities
    A sewer cap is required if a house to be demolished is served by the City sewer. If the sanitary system was a septic tank or cesspool, then the abandonment of that system must be inspected under a decommission permit.
  4. Intent to Demolish
    If you, the applicant, are not the owner of the property listed on the deed, you will need a completed intent to demolish form signed by all property owners. If you recently purchased the property, you will need to show proof of ownership.

  5. Tree Code Requirements
    Title 11 Tree Code requirements are triggered by the criteria below, and must be met prior to a demolition permit being issued. Your permit can be taken in for review without tree preservation information, but you must complete your tree preservation requirements during the 35 day demolition delay period. Planning and Zoning won’t approve the demolition permit until the Title 11 Tree Code requirements are met. Because the permit can’t get issued until Planning and Zoning signs off on the application, failure to meet the Tree Code requirements could delay issuance of the permit. Information on Title 11 Tree Code requirements can be found at

    Please note: The tree preservation requirements under Title 11 DO NOT apply in the following situations
    • On sites smaller than 5,000 sq. ft.
    • On sites that have no existing trees 12” or more in trunk diameter, or no street trees 6” or more in trunk diameter
    • On sites where the applicant has brought an arborist report in with the application certifying that the trees on the site are dead, dying, or a nuisance species
    • On sites that are in a zone that allows more than 85% building coverage.
