Permitting and Inspections
Portland homeowners should check Permitting and Inspections, zoning, flood information, rental registration, building permits, and Citizen Self Service before starting residential projects.
Permit and scope questions
Portland's Permitting and Inspections office provides building permits, online applications, fee schedules, permit type guides, codes, ordinances, and inspection resources through Citizen Self Service.
Zoning and placement
Zoning administration, flood information, maps, land use zoning, and zoning board issues can affect whether a residential project may proceed before the building permit is issued.
Building and trade review
Residential projects may involve building permit review, inspections, zoning staff meetings, rental inspections, and code compliance depending on the property and use.
Discuss your project early when: Call before applying if the project includes an addition, deck, basement finish, rental unit, exterior change, flood-prone property, zoning uncertainty, or work that affects occupancy.
