Electric & gas: PG&E
Pacific Gas & Electric
As of 2026-05-30, PG&E's default residential electric plan is E-TOU-C, a time-of-use plan with a 4-9 PM peak window. Alternatives include E-TOU-D (5-8 PM peak), EV2-A (whole-home TOU optimized for EV charging, lowest rates 12 AM-3 PM daily), and E-ELEC (a newer flat-rate-style plan for fully-electric and NEM 3.0 solar households, and the default plan when registering new residential solar under NEM 3.0). In March 2026, PG&E restructured residential rates under AB 205's income-graduated fixed charge framework, adding a flat Base Services Charge (~$24/month for non-CARE households; CARE/FERA pay a reduced fixed fee) paired with a per-kWh price cut. Households planning heat-pump HVAC, EV charging, or whole-home electrification may want to compare E-TOU-C, EV2-A, and E-ELEC; verify current rates and plan rules at the provider site.
$15,000–$30,000 — Installed cost for a single-family Bay Area home reroofing with architectural asphalt shingles (roughly 1,800–2,500 sq ft roof area) including tear-off of one existing layer, underlayment, flashing, ridge venting, Title 24 cool-roof compliance where applicable, and solar-ready prep (reinforced rafters and flashings sized for future PV penetrations), pre-incentive. Excludes structural reframing, tile roofing, full PV install, and historic-district custom materials.
You may qualify for incentives — verify current programs and eligibility before relying on them.
Permit snapshot
building permit
As of 2026-05-31, residential reroof projects in San José typically require a building permit issued by the Planning, Building and Code Enforcement (PBCE) Department; applications are submitted via the SJPermits.org online portal. For a like-for-like reroof, plans are typically not required, but the project is reviewed against weight, material, and code criteria — if the overall roofing weight exceeds 7 pounds per square foot, the existing roof structure must be justified by California Residential Code or California Building Code rafter span tables or by engineering calculations. California Title 24 Building Energy Efficiency Standards 'cool roof' requirements typically apply when 50% or more of the roof surface over conditioned space is replaced; in that case, CRRC-rated roofing products are typically required and documentation may be requested at permit or inspection (Title 24 also provides alternative-compliance paths such as R-38 ceiling insulation, an attic radiant barrier, no ducts in the attic, or R-2 above the roof deck — verify which path applies). If the reroof involves removing and reinstalling, relocating, or altering existing solar PV, HVAC, or other rooftop equipment, additional electrical or mechanical sub-trade permits are typically required. Properties on the City's Historical Resources Inventory typically require an additional Planning review. Verify current submission requirements, Title 24 compliance path, and any solar-attachment scope with the Building Division before scheduling the reroof.
