What is a Driveway Design Exception?
The City of Portland Bureau of Transportation has multiple rules which impact the design of driveways.
These include Title 17.28.110 - Driveways- Permits and Conditions, TRN 10.40- Driveways-Operation and Location, and TRN 10.42- Access Requirements for Parking Structures. If a project cannot meet the requirements but would still like to seek vehicular access, a Driveway Design Exception can grant an exception to the standards.
An overview of the changes that went into effect 1-1-2022 is available in the document below.
Applying for a Driveway Design Exception does not guarantee approval. The request will be reviewed by a PBOT Development Review Traffic Engineer. The engineer may approve, approve with conditions, or deny the request. Exceptions are granted only for a specific development proposal. They are not transferrable from one development proposal to another.
A Driveway Design Exception cannot modify a zoning code (Title 33) standard and does not alter completed land use reviews. A new or amended land use review may be required to incorporate changes from a successful Driveway Design Exception.
It is a good idea to discuss your case with PBOT Development Review staff before filing a Driveway Design Exception. If you have an in-process review such as a building permit or land use case, please work with the assigned PBOT reviewer. If you do not have an in-process review, you may contact PBOT Development Review staff by visiting the Development Services Center or calling 503-823-7002. Please leave a message and someone will return you call as soon as we can.
Who reviews Driveway Design Exception Requests?
Driveway Design Exception requests are reviewed by the PBOT Development Review traffic engineers. It is probable the engineer reviewing your request is not familiar with your project. Please do not assume the engineer knows anything about your project or will have time to do background research into matters which are not the result of PBOT requirements. If there are conflicts with requirements from other bureaus that are the reason why you are applying, please explain this in your submittal. If there are conflicts with utilities, street trees, or other physical barriers that would make meeting the standard difficult or prohibitively expensive, please explain this as well in your submittal.
What is the fee for a Driveway Design Exception?
There is a non-refundable fee of $250 per application. This applies whether the driveway is for residential, commercial or industrial use. (Portland Policy Document TRN-3.450) . Denials will not be refunded.

How long does the review take?
Plan on a minimum of 5 weeks for the initial review. Additional time may be needed for revisions. The more complex the situation, the longer the review is likely to take.
For DDE’s associated with a land use review, PBOT recommends the DDE be submitted at the time of land use application. The completed DDE must be submitted prior to PBOT considering the land use application complete. The DDE must be reviewed and approved by PBOT prior to PBOT supporting approval of the land use review.
For projects without a land use review, just a building permit, PBOT recommends submittal of the completed DDE with the initial building permit submittal.
I still have questions. Who can I contact?

What if I disagree with the outcome of a Driveway Design Exception request?
Safety is the primary consideration in reviewing Driveway Design Exceptions. Not all requests will be able to be accommodated. You may work with the traffic engineer reviewing your request to see if there is a way to modify the proposal to achieve approval. This may require submittal of a new application depending on the situation. Once a decision is issued, the Driveway Design Exception decision is final and conclusive. The decision may not be appealed under 17.28.110.
