The Licensing and Registration Office administers the rental housing registration and schedules the property inspections for buildings that contain short term and long term rental units within the City of Portland. All property owners are required to annually register residential rental units with the City's licensing and registration Office by December 31st or within thirty (30) days of renting a property.  This includes rooms, apartments, condominiums, and houses.

Guidance on Rental Units

A rental unit can be a rented room, apartment, house or condominium for any length of time:
  • Long term (>30 days) - Leased or month-to-month residential units; or
  • Short term (<30 days) - Any type of overnight, weekly or summer or seasonal residential rental through AirBnB, similar websites and other means
Please note: An Owner is not required to register the unit they occupy for Long Term only, but must register rental units, and have their own unit inspected for safety purposes.  We inspect the entire building.  A fire or other hazard in the owner's unit may impact the safety of the rental units.
