San Francisco insulation upgrades pay back fast given PG&E rates and SF cool climate (but heating-dominant). Most pre-1980 SF homes have R-13 to R-30 attics — well below the modern R-49+ target. Air sealing before insulation matters in older Mission and Inner Sunset homes. BayREN/PG&E rebates available. NeedInstall connects you with SF insulation contractors who handle BayREN paperwork, blower-door testing, and proper detailing for older homes.
SF attic top-up to R-49+: $2,500-$6,000 (premium market). Wall dense-pack: $5,000-$12,000 retrofit. Basement spray-foam: $4-$7 per board foot. CA requires a C-2 insulation license. BayREN/PG&E rebates ($1,000-$5,000+). Title 24 + HERS testing required.
