HOMES IN CEDAR MILL
The median home was built in 1992. A first or second replacement is common in homes this age.
70% of homes heat with utility gas, so gas water heaters with existing venting are common here.
U.S. Census Bureau, American Community Survey ACS 2024 5-year ↗ (2020-2024). Heating fuel is what homes use to heat the house. It often, but not always, matches the water heater’s fuel.
LOCAL CONDITIONS
Oregon's statewide guidance says a replacement water heater in an existing home still has to meet today's code for earthquake straps, raising the heater in a garage, the relief valve drain line, thermal expansion protection and combustion air. Pipe sizing, a drip pan and existing water pressure above 80 psi don't have to be brought up to code.
The water heater item is only $37, but Washington County's $236 minimum plumbing fee (FY 2026-27) applies. A basic swap costs $264.32 with the state surcharge.

Tualatin Valley Water District (TVWD). In 2025, 73% of TVWD's supply came from Portland's Bull Run and Columbia South Shore sources, with the rest from the Joint Water Commission and ASR; Willamette Water Supply System deliveries are expected as early as late 2026.: Soft: Portland Water Bureau supply 6–11 ppm (under 1 grain per gallon); Joint Water Commission supply about 34 ppm (2 grains per gallon). Mixing in groundwater in summer can raise hardness a bit.
