Replacing a water heater in Oatfield.
Oatfield is unincorporated, so Clackamas County issues the plumbing permit to replace a water heater. It's the stretch along Oatfield Road, named for the pioneer Oatfield family, between Milwaukie and Gladstone and west of I-205. Most homes are owner-occupied houses from the 1960s and 1970s. Oatfield completely surrounds the tiny city of Johnson City, which uses a different permit process.
Oatfield is an unincorporated community in Clackamas County, so county offices handle permits.
- Permit to replace with the same type
- Yes · Clackamas County Building Codes Division
- Permit fee
- Clackamas County Building Division Fees, 2026/2027: the water heater item is $31.75, but you pay the $123 plumbing minimum, plus Oregon's 12% state surcharge (about $137.76).
- Who gets the permit
- The state Building Codes Division says the permit belongs to whoever does the work, homeowner or contractor. A hired company needs a Construction Contractors Board license and the right state plumbing contractor license; licensed contractors can use state plumbing minor labels ($140 for 10) for water heater replacements. The county takes homeowner applications, with homeowner responsibility forms, by email or at its Oregon City lobby.

HOMES IN OATFIELD
What Oatfield homes are like.
1975Median year built
64%Built before 1980
85%Owner-occupied
61%Heat with utility gas
87%Single-family homes
About 64% of homes were built before 1980. Older homes often have older venting, smaller closets and shutoff valves that should be checked before install day.
61% of homes heat with utility gas, so gas water heaters with existing venting are common here.

LOCAL CONDITIONS
What’s different in Oatfield.
A county island around Johnson City
Oatfield completely surrounds Johnson City, a separate city. Clackamas County's permit table sends building and plumbing permits in Johnson City, Milwaukie and Gladstone through those cities, with the county handling only electrical. In unincorporated Oatfield, the county issues every permit. Find out which side of the line your property is on before a plumber applies.
Ask: Is my address in unincorporated Oatfield or inside Johnson City, Milwaukie or Gladstone?

1960s–70s houses, mostly owner-occupied
Census estimates put nearly half of Oatfield homes in the 1960s and 1970s and about 85% in detached houses; roughly 85% of households own their home. About 61% heat with gas, and a few still use oil. In houses this old, Oregon's replacement rules often mean adding things the original install never had: earthquake straps, raising a gas heater in the garage, a thermal expansion tank and a proper relief-valve drain.

Oatfield Road's water main is being replaced
Oak Lodge Water Services, which supplies Clackamas River water to Oak Grove, Jennings Lodge and parts of Milwaukie and Gladstone, named the Oatfield Road main in its 2020 Water Master Plan as one of the biggest sources of main breaks. Its board approved the design in November 2023, with construction planned over three fiscal years. Breaks and new connections can stir sediment into home lines, so flush your heater after any outage or boil notice on your street.
Ask: If water service was recently shut off for main work, can you flush the tank and check the inlet screen?

Soft Clackamas River water
Whether you're billed by Oak Lodge or Clackamas River Water, the water comes from the Clackamas River, which Clackamas River Water calls soft. Mineral scale is less of a worry for a new heater here than in hard-water areas.
