Whether you are building on property located in the City of Los Angeles Methane or “Methane Buffer Zone,” Playa Vista (Los Angeles South Bay area) or within the Building Restriction Zone designated by the Orange County Fire Authority, you will need a certified methane soil gas investigation report.
