Portland Maine Permitting and Inspections Guide

Portland homeowners should check Permitting and Inspections, zoning, flood information, rental registration, building permits, and Citizen Self Service before starting residential projects.

Permit takeaway

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.

Call before applying 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.
