Policy and Procedures

The Portland Bureau of Transportation administers the on-street carpool parking program in order to improve access to the Central City and reduce the number of single-occupancy vehicles throughout the metropolitan area. Eligible carpoolers may purchase monthly permits.


Carpoolers must live outside the eligibility zone. Carpoolers must work or go to school within the district that they are carpooling to.  See map of eligibility zone and districts here.

  1. All members of the carpool must commute together and place of employment must be in to the Downtown Meter District or the Lloyd Meter District at least four days each week, both ways. The commute route must make common sense, and the carpool members must share at least 50% of the commute route together.
  2. Carpool members must be 14 years and older. All carpoolers must be Licensed Drivers (not required for students under 18)
  3. Carpoolers may drop off members within the boundary before parking, but all carpool members must work or go to school in the area within the boundary.

Carpool Parking Locations

Carpool parking is available at the following SmartPark parking garages: SW 1st & Jefferson, SW 3rd & Alder, SW 10th & Yamhill, NW Naito & Davis, and O’Bryant square.  For information on availability and pricing, contact SmartPark directly at or 503-790-9302. 

On-street carpool parking is available at 5-hour meters in the Downtown and Lloyd Meter Districts.

Parking is on a first-come first served basis. No spaces are reserved for individual carpools.

Application and Renewal Process for SmartPark Parking Garages

1. Go to SmartPark's web site to apply. 

2. The City reserves the right to not renew permits, with 30 days written notice, if the number of carpool spaces allowed in a SmartPark facility is reduced for any reason.

Application and Renewal Process for On-Street Parking

  1. New members must complete and sign the new member application. It is the responsibility of the contact person to review the policy and procedures with new carpool members. Payment is due on the 20th of the month previous to when you wish to start.
  2. Renewal forms will be mailed with monthly permits. Renewals and checks must be received by the 20th of each month to avoid $20 late fee. Permits are issued by  MAIL ONLY, no exceptions.
  3. The renewal form must be completed in full monthly, including any changes in members. Information regarding carpool members' names, addresses, phone numbers, work locations, and work hours must be kept current and updated.
  4. Permits are valid only for the month they are issued. There is no grace period for using a previous month's permit or prorating of monthly fees.
  5. Carpoolers providing inaccurate or incomplete information will not be issued a permit.
  6. Carpoolers must renew permits monthly, even during vacation periods, in order to remain in the program.
  7. Only a cashier's check or money order is accepted after more than one incident of a returned, non sufficient fund (NSF) check. There is a $35 returned check charge. Each carpool participant is financially responsible for keeping the payments up to day.


  1. The Portland Bureau of Transportation will verify information on carpool parking permit applications.
  2. Employment verification is required prior to any issuance of permits. If employment cannot be verified over the telephone by your firm's local human resources department, applicants must provide written employment verification and specific work hours on company letterhead issued from the respective personnel office.
  3. Carpool participants attending school (college, high school, or special trade schools) must attach enrollment verification and school hours from their school.


  1. The Portland Bureau of Transportation will randomly monitor a percentage of all carpool programs each month to determine authenticity.  
  2. An instance of not supplying accurate, completed or up-to-date information will result in the carpool members being ineligible for any carpool parking program administered by the Portland Bureau of Transportation for a minimum of one year.
  3. Carpool parking permits are not transferable.

Lost Permits

  1. Portland Transportation is not responsible for lost or stolen permits, gives no refunds, does not prorate, reserves the right to refuse to reissue a permit in the case of misuse, and will impose an appropriate replacement fee.

Parking Citations

  1. Vehicles parked incorrectly in the on-street program, or without a properly displayed current month's permit will be cited. There is no grace period for monthly permits.
  2. Permits must be visible to City of Portland Parking Code Enforcement Officers. Vehicles without a visible carpool permit hung from the rear view mirror with the side showing the month valid turned outward will be cited.
  3. In the event a citation is issued, carpoolers are responsible for following the procedures set forth by the Multnomah County Circuit Court (listed on the back of the citation).
