As of 2026-05-30, SCE residential electric service runs on time-of-use (TOU) rate plans by default. The standard TOU option is TOU-D-4-9PM (4 PM-9 PM weekday peak window). Alternatives include TOU-D-5-8PM (5 PM-8 PM peak window for households that cannot shift evening load) and TOU-D-PRIME, a rate reserved for customers with an EV, plug-in hybrid, residential battery, or an electric heat pump for space or water heating. TOU-D-PRIME features lower peak rates paired with a higher daily basic charge (about $0.79/day, roughly $24/month). Under California's Net Billing Tariff (NEM 3.0), new residential solar customers in SCE territory must be on TOU-D-PRIME. Legacy tiered and earlier TOU plans (TOU-D-A, TOU-D-B, TOU-D-T) remain available to existing customers but are closed to new enrollment. Households planning heat pump HVAC, EV charging, battery storage, or whole-home electrification may want to compare TOU-D-4-9PM and TOU-D-PRIME; verify current per-kWh rates and plan rules at the provider site before switching.
As of 2026-05-30, LADWP residential electric customers default to rate schedule R-1A (Standard), a three-tier inclining-block structure (Tier 1 / Tier 2 / Tier 3). During summer high-demand months all three tiers price separately; in winter Tiers 2 and 3 are billed at the same rate. LADWP divides the City into two temperature zones (Zone 1 cooler, Zone 2 hotter inland) and gives Zone 2 a larger Tier 1 allowance. Bills also include a monthly Power Access Charge (PAC) that scales with the customer's highest energy use over the prior year. A time-of-use option, R-1B (TOU), is available on request. Important: LADWP is a municipal utility owned by the City of Los Angeles and is NOT regulated by the California Public Utilities Commission (CPUC); rates are set by the LA Board of Water and Power Commissioners. LADWP operates its own net-metering tariff (system cap 1 MW) and is NOT subject to CPUC's NEM 3.0 / Net Billing Tariff (NBT), which governs only the investor-owned utilities PG&E, SCE, and SDG&E. Homeowners should verify current rates on the LADWP residential rates page before sizing a project; LADWP filed rate increases for 2026.
$12,000–$26,000 — Installed cost for a single-family SoCal 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 reroofs, full PV install.
As of 2026-05-30, the LADWP Consumer Rebate Program pays a per-square-foot rebate for qualifying cool roofs installed over conditioned space: a base rebate of $0.20 per square foot and an enhanced rebate of $0.60 per square foot for products meeting higher solar-reflectance thresholds. Per-project caps and qualifying-product lists apply; homeowners should verify the current schedule on the LADWP CRP page before purchase. Roofing material must be CRRC-rated and meet LADWP's minimum 3-year SRI thresholds: for the base rebate, SRI greater than or equal to 78 (low-slope, less than or equal to 2:12) or SRI greater than or equal to 20 (steep-slope, greater than 2:12); for the enhanced rebate, SRI greater than or equal to 85 (low-slope) or SRI greater than or equal to 35 (steep-slope). LADWP residential electric account required; product must be installed over conditioned (heated/cooled) space. Application is post-installation and must be postmarked within 12 months of the purchase date.
As of 2026-05-31, residential reroof projects in the City of Los Angeles typically require a building permit from LADBS, typically filed by a C-39 licensed roofing contractor registered with LADBS. 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 in a Historic Preservation Overlay Zone (HPOZ) require HPOZ clearance from City Planning before LADBS will issue the reroof permit — this is reviewed under LAMC §12.20.3 and processed as a Certificate of Appropriateness, Certificate of Compatibility, or Conforming Work on a Contributing/Non-Contributing Structure, depending on the project scope. 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 LADBS submission requirements, Title 24 compliance path, HPOZ status, and any solar-attachment scope with LADBS and City Planning before scheduling the reroof.
