Build a Deck
Permits from the Planning and Building Divisions are required for all decks over 2.5 feet (30 inches) above the ground or decks that are covered by a roof or canopy for an area of 200 square feet or greater.
The permitting process ensures the structure is safe, complies with setbacks, and is not harmful to utilities or public infrastructure.
Application Review Criteria
If your deck, porch, or porch cover requires a building permit, the Planning Division will review your applications for compliance with Oregon City Municipal Code. Generally speaking, the following chapters of the code are directly applicable to decks, patios, and covers:
- The property's underlying zone
- OCMC 17.54.030 - Supplemental Zoning Regulations and Exceptions
However, different properties have different characteristics, configurations, and dimensions. Depending on the circumstances, an Accessory Structure application might involve additional review if the project requires a Variance or is located in:
- A historic district or historically designated lot
- The Flood Management Overlay District
- A Geologic Hazard area
- The Natural Resource Overlay District
- The Willamette River Greenway District
- A Non-conforming lot, site, or structure
For changes to designated Historic structures, or homes within a Historic District, see the Historic Review Resources page for more information.

Planning Review Fees
Once we receive an Accessory Structure application, Planning Division staff must take time to review it to ensure the project complies with all relevant codes. The fees we charge are related to the time and effort typically required to review your project.
