Marion County Plumbing Permit Requirements
Marion County is responsible for issuing all building permits in its unincorporated areas. For properties within incorporated cities that have contracted with Marion County for building inspection services, permit jurisdiction may vary by permit type.
The Oregon Plumbing Specialty Code (OPSC) is enforced as part of the Marion County Building Code. Specific plumbing permit requirements and application forms can be found on the Marion County Building and Planning website. For detailed information on when a plumbing plan review is required, refer to the county's Design and Code Information resources.
For properties in unincorporated areas, Marion County's Building Inspection Division reviews construction and remodeling plans. They also administer the Onsite Sewage Treatment and Disposal Program within the county.
A plumbing permit is generally required for the following types of work:
- Replacement of water heaters or underground piping.
- Alterations to piping within walls, ceilings, or under floors.
- Installation of a plumbing fixture where none previously existed.
- Emergency repairs or alterations to a section of pipe five feet or longer.
A permit is typically not required for minor repairs such as replacing a sink, toilet, or faucet that is not concealed, or repairing countertops, shower heads, rain gutters, or downspouts.
When applying for a plumbing permit, two sets of plans must be submitted for review. Certain complex installations, such as medical gas systems, commercial potable water pressure booster pump systems, or water service lines with an interior diameter of two inches or larger (unless designed by a licensed engineer), may require additional plan review.
