Climate & Environmental Considerations
"Los Angeles construction must address extreme heat waves, high wildfire risks, and significant seismic activity. Hempcrete is an ideal material for this region because it is non-combustible, provides exceptional thermal mass to mitigate the urban heat island effect, and offers structural flexibility that performs well during earthquake events common in Southern California."

Frequently Asked Questions
Yes, hempcrete is legal for construction in Los Angeles. Following the 2022 inclusion of hemp-lime into the International Residential Code (IRC), Custom Green Construction Inc. ensures all projects meet California Title 24 energy standards and local seismic requirements, providing a fully permitted and compliant sustainable building alternative.
Hempcrete is highly effective during Los Angeles heat waves due to its high thermal inertia and breathability. It slowly absorbs and releases heat, keeping indoor temperatures stable and significantly reducing reliance on air conditioning. This natural regulation helps homeowners lower energy bills while maintaining comfort during peak Southern California summer temperatures.
