Portland's Carpool Program

Portland offers two options for carpoolers looking to use the public parking system, an on-street carpool permit and a SmartPark Garage carpool permit. Both programs are designed to reduce congestion, improve air quality, and reduce the number of single-occupant vehicles throughout the metropolitan area. Carpool permits are currently available in the Downtown and Lloyd Meter Districts (click here for map).

General Requirements

  • The intent of the carpool program is to provide carpool options for those who do not have easy access to public transportation. Carpoolers must live outside the area identified in this map to qualify for a carpool permit.
  • There is a 2-person minimum.
  • All members of the carpool must commute together to the Downtown Meter District or the Lloyd Meter District  at least four days each week, both ways. The carpool members must share at least 50% of the commute route together.
  • 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 members must be 14 years and older. All carpoolers must be Licensed Drivers (except for students 14 years old to 18 year old).

Financial Incentives for Carpooling

TriMet offers a CarpoolCheck program that allows companies to pay part of their employees' carpool parking costs at selected parking locations in downtown Portland where there is a monthly parking fee. CarpoolChecks are accepted for both the on-street and SmartPark Garage carpool permit program, and are also accepted by most of the operators in the downtown area. If you are an employee interested in the Carpool Check program, please contact your company's carpool program administrator. If you are a company interested in funding a Carpool Check program, please call (503-962-7670) or email TriMet for more information.
