Mei Lin

Mei Lin is 9Builders sustainability and home systems contributor, covering green building practices, HVAC, solar, and whole-home maintenance for Bay Area homeowners. Her coverage includes Title 24 compliance, heat pump retrofits, solar-plus-storage economics under California NEM 3.0 rules, and Passive House principles adapted for mild Bay Area microclimates. Mei writes practical maintenance guides tuned to the seasonal rhythms of Northern California — roof and gutter care before atmospheric rivers, wildfire defensible space, and summer cooling strategies for homes without central AC. She also tracks rebate programs and utility incentives that change year over year.
