Permit Fees
Deck permits across Oregon are administered at the city or county level, and requirements vary between jurisdictions. In Portland, the dominant building code in force is 2021 Oregon Residential Specialty Code (based on 2021 IRC with Oregon amendments). No building permit required if: no part of the walking surface is more than 30 inches above adjacent grade AND no portion of the deck is closer than 3 feet to an adjacent property line. Zoning requirements still apply even for exempt decks. That said, any deck that meets any one of the following usually requires a permit regardless of size: attached to the dwelling, over 30 inches above grade, covered with a roof, or serving a required exit door. Portland processes residential plan reviews in varies by project. contact portland permitting & development at 503-823-7300..
