Do You Need a Deck Permit in Portland?
Permit Exemption
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.
If your deck does NOT meet all exemption criteria, you must obtain a permit before construction. Building without a required permit can result in fines, stop-work orders, and required demolition.
