What you should research before submitting for a permit or land use review. Find out what you need for a permit or land use review.
- Legal description of the property (called the Tax Roll on Portland Maps)
- Owner's name & address
- Tax Account number (also called the R number or Property ID on Portland Maps)
This information is available on Portland Maps under the Property Description in the Assessor Detail. If there is not an address, you can use the Tax Account Number.
Utilities and services Information
- Fire access
- Public streets
- Sanitary sewer
- Stormwater facilities
- Water supply
This information is also available on Portland Maps. Streets that are publicly maintained will appear white on Portland Maps. If there is no water or sewer nearby, it can be expensive to connect.
System development charges
These are fees charged to new development, additions and changes of use. These fees help offset the impact your project will have on the City’s storm and sanitary sewer systems, parks and recreation facilities, water, and street systems.
Permit history and land use decisions
Research the permit history of the property. For commercial sites, you should know what the last permitted occupancy or use was. For residential sites, if you are altering a home or duplex, check to see what was done with a permit. For commercial and residential sites, you should also know if there are any land use decisions that could impact your project.
Some information may be on Portland Maps. How to Access Public Records has information on requesting permit plans and land use records.
Other things to learn about a site
Some sites may need more research. For example:
- Oregon Department of Environmental Quality has information about environmental clean up sites
- Multnomah County Health Department has information on small water systems (Not through by Water Bureau)
- Oregon Department of Transportation if the site is close to state highways or infrastructure.
- Local water and drainage districts
Public Works permitting
When properties develop, public services are needed to serve these developments. Services such as sanitary sewer, water, street improvements and stormwater management are necessary.
You need a Public Works permit for privately funded public improvements in a public right-of-way in the City of Portland. Because these improvements are for public use, City staff must review and approve plans before construction.
A public works improvement and permit may be required as part of a building permit review or as part of a Land Use Review, such as a subdivision. At the time of these reviews, staff will inform an applicant of the requirements. The Public Works Permit Process has more information
Projects that typically require a Public Works Permit include:
- Curb and street pavement construction
- Sewer mainline extensions
- Sidewalk reconstruction
- Stormwater facilities for street drainage
- Street lighting
- Water main extensions for subdivisions in proposed (new) public rights-of-way
