The City of Portland’s Bureau of Development Services has created a code guide for cannabis businesses - Marijuana Producers and Marijuana Processors, specifically - who are obtaining permitting for their building.

Here is a link to the guide:

This code guide should be helpful both for future business owners who have not yet chosen a site, and for business owners who already have a site for their business and are in the process of getting the building properly permitted.

The code guide covers items such as:

  • Building occupancy classifications for different kinds of cannabis businesses
  • Ventilation requirements
  • Mechanical permitting
  • Exhaust and air intake
  • Detection and alarms

Marijuana Producers and Marijuana Processors in the City of Portland are REQUIRED to obtain final permitting for their building before being granted a City of Portland Marijuana Regulatory License and beginning operations. In some cases, a Temporary Certificate of Occupancy may be used to satisfy this requirement. More information on using a Temporary Certificate of Occupancy to satisfy cannabis business licensing requirements can be found by clicking here.

The cannabis business code guide may also be found in both the “Learn About Portland Cannabis Rules” or the “Apply/License Cannabis Businesses” sections of the City of Portland’s Cannabis Program website at
