    Healthy Homes for Oregon — Marine Damp, Smoke Season, Cascadia

    Virtual Home Health Score assessments on both sides of the Cascades. GaiaCrete™ detailed for Oregon's specialty energy code and marine climate. Founding Mr Hemp House® dealer territories open by ZIP code.

    • Persistent marine rain and mold

      Western Oregon's long wet season keeps walls and crawlspaces damp for months, and mold grows without any dramatic leak event.

    • Annual wildfire smoke

      Oregon smoke episodes now recur every late summer, pushing hazardous particulate into homes with no filtration plan.

    • Cascadia seismic exposure

      Oregon sits above the Cascadia subduction zone, so structural and non-structural bracing requirements shape how walls are built.

    What Climate Zone 4C-5B Means for Oregon Homes

    Oregon splits sharply at the Cascades: a marine Zone 4C west side with eight months of rain, and a dry Zone 5B-6B high desert east. West-side homes fight persistent low-grade moisture and mold rather than dramatic weather. Statewide, late-summer wildfire smoke has become an annual indoor air event, and Oregon's energy code is among the more demanding in the country.

    • Oregon Residential Specialty Code and Oregon Energy Efficiency Specialty Code

      Oregon writes its own specialty codes based on the I-Codes, with energy requirements stricter than the base IECC.
