California-Ready Healthy Homes — Title 24, Wildfire, and Indoor Air
Home Health Score assessments statewide. GaiaCrete™ contributes to Title 24 and CALGreen compliance. Founding Mr Hemp House® dealer territories open by ZIP code.
Wildfire and smoke exposure
California wildfires drive indoor air quality events that last weeks. Sealed homes with active ventilation, low-VOC materials, and mold-resistant assemblies protect health when the outdoor air is unbreathable.
Title 24 compliance
California's Title 24 pushes higher envelope performance and low-carbon material specification every code cycle. GaiaCrete™ and healthy building material selection help projects meet and exceed compliance.
Seismic and moisture events
California homes must handle seismic loading, atmospheric river moisture events, and rebuild cycles. Monolithic vapor-permeable wall systems perform better across all three.
What Climate Zone 3B-5B (varies) Means for California Homes
California's climate zones range from coastal Mediterranean to inland dry to alpine cold. The state also leads the country on building code stringency — Title 24 sets efficiency, indoor air quality, and low-carbon requirements above baseline IECC — making healthy, low-carbon construction not just a preference but increasingly a code minimum.
California Building Standards Code (Title 24)
Includes Part 6 Energy Code and Part 11 CALGreen — the country's most comprehensive green building code framework.
Start With Your Home Health Score in California
Digital Home Health Score screening is available nationwide. In-person Professional Healthy Home Assessments are not yet scheduled in California. Contact Mr Hemp House® for current product, dealer, consultation, and installation availability. Availability varies by market.
Home Health Score
A free screening that scores your home across indoor air quality, moisture and mold risk, building materials, and ventilation — so you know where to look first.
Healthy Home Assessment
A professional walkthrough of materials, moisture conditions, and ventilation, delivered as a prioritized action plan. Screening and guidance — not a medical or diagnostic service.

- Thermal planning reference R-2.5+ per inch
- Class A surface burning characteristics (ASTM E84) — material behavior, not an hourly assembly rating
- Alkaline mineral composition may be less conducive to some biological growth conditions
- 100% Biobased Carbon Content (ASTM D6866-22)
- Vapor-permeable, hygroscopic, no added VOCs
- Net carbon sink by design
Actual thermal performance varies by formulation, density, moisture content, installation method, and complete wall assembly. Final whole-wall thermal performance depends on the complete assembly, including material density, framing, finishes, thermal bridging, moisture conditions, and installation.
