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.

Permit snapshot
building permit
As of 2026-05-31, residential reroof projects in San Francisco typically require a building permit from the Department of Building Inspection (DBI). A licensed C-39 roofing contractor registered with the City of San Francisco is typically required to apply online. 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 — for low-slope roofs this typically means installing a Cool Roof-rated (CRRC) membrane meeting minimum Solar Reflectance Index (SRI) thresholds; alternative-compliance paths (e.g., higher attic insulation, radiant barrier, R-value above the deck) may apply for steep-slope assemblies. Properties in any of San Francisco's many historic districts or with individual historic-resource designations may additionally require Planning Department review for visible changes to roof profile, material, or color — this is typically a discretionary process that can add weeks. If the reroof involves removing, reinstalling, relocating, or altering existing solar PV, HVAC, or other rooftop equipment, additional electrical or mechanical sub-trade permits are typically required. Verify current submission requirements, Title 24 compliance path, historic-review status, and any solar-attachment scope with DBI and Planning before scheduling the reroof.
