Electric & gas: SDG&E
San Diego Gas & Electric
As of 2026-05-30, SDG&E's default residential plan is TOU-DR1, a three-period time-of-use plan with on-peak / off-peak / super off-peak windows and a 4-9 PM peak. TOU-DR2 offers a simpler two-period structure with the same 4-9 PM peak. Households with EVs, batteries, or heat pumps may benefit from TOU-ELEC (designed for electrified homes), or from EV-specific plans: EV-TOU-5 (whole-house TOU with the lowest overnight pricing for home charging and the Solar Billing Plan) and EV-TOU (a separate-meter option). TOU-DR-P and EV-TOU-5-P are event-based variants that add Reduce Your Use events (up to 18/year) with a $1.16/kWh event adder during 4-9 PM. Plans require 12-month commitments; homeowners should verify the current default and rate cards on the SDG&E pricing plans page before assuming a peak window or rate.

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 the City of San Diego typically require a building permit from the Development Services Department (DSD), typically filed by a C-39 licensed roofing contractor authorized to perform the work. 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) labeled and certified product meeting minimum Solar Reflectance Index (SRI) thresholds; alternative-compliance paths (additional attic insulation, radiant barrier, R-value above the deck) may apply for steep-slope assemblies. Properties containing a structure 45 years or older may trigger a DSD historical resource review; properties containing a designated historical resource or located within an adopted historic district always require a permit for renewal of roof coverings, and additional historical review applies before DSD will issue the reroof permit (per Information Bulletins 580 and 581). 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 DSD submission requirements, Title 24 compliance path, historical-resource status, and any solar-attachment scope with DSD before scheduling the reroof.
