As a homeowner or property manager in Gresham, understanding local plumbing codes is crucial for maintaining safe, efficient, and compliant plumbing systems. Whether you’re planning a remodel, new installation, or routine maintenance, following Gresham’s plumbing regulations helps avoid costly fines, unsafe conditions, and ensures your plumbing functions properly for years to come.
In this ultimate 2025 guide, Einstein Pros Gresham breaks down everything you need to know about the current plumbing code to keep your home’s plumbing up to standard.
What Is the Gresham Plumbing Code?
Gresham’s plumbing code adopts the Oregon Plumbing Specialty Code (OPSC), which aligns closely with the 2021 Uniform Plumbing Code (UPC), with some local amendments specific to Gresham and Multnomah County.
The code sets the minimum requirements for plumbing system design, materials, installation, and maintenance to protect public health and safety. It covers all aspects — from water supply and drainage to venting and fixture installation.

Key Updates in the 2025 Gresham Plumbing Code
The 2025 edition incorporates important updates that homeowners and contractors should be aware of:
- Water Efficiency Requirements: Increased emphasis on water-saving fixtures such as low-flow toilets and faucets, in line with Oregon’s water conservation goals.
- Backflow Prevention: Stricter rules on installing backflow prevention devices to protect potable water from contamination.
- Ventilation Standards: New standards for venting systems to improve plumbing airflow and prevent sewer gases.
- Materials & Pipe Standards: Certain materials like lead-based solder and galvanized steel pipes are restricted or banned.
- Greywater Systems: Updated guidelines for greywater reuse and recycling systems, promoting sustainable water use.
Common Plumbing Permits in Gresham
Any plumbing work that involves installation, replacement, or significant repair requires a permit issued by the City of Gresham Building Division. Examples include:
- Installing or replacing water heaters, tanks, or pumps
- Adding new plumbing fixtures (toilets, sinks, showers)
- Re-piping or altering water or drainage lines
- Installing backflow prevention devices
- Setting up greywater or rainwater systems
Always check permit requirements before starting work to ensure compliance. Einstein Pros Gresham can help guide you through this process smoothly and efficiently.
