ADU Electrical Service with Pacific Gas and Electric (PG&E)

How to get a service upgrade, a new or separate meter, or a relocated service from Pacific Gas and Electric (PG&E) when you add an ADU, and what our electrical plans give you for that application.

Who PG&E serves

Investor-owned utility providing gas and electric service across a large service area in northern and central California. Of the California places we cover, 267 are served mainly by Pacific Gas and Electric (PG&E), and together they issued 34,032 ADU building permits from 2021 through 2025.

How PG&E handles new and upgraded service

Pacific Gas and Electric (PG&E) handles new service, service upgrades and meter changes through its Your Projects portal. This is separate from the building permit, so start it as soon as the electrical load calculation shows what the ADU needs. The steps PG&E describes:

  1. Submit an application through Your Projects and upload required documents, including permits if applicable.
  2. PG&E assigns a dedicated Job Owner who contacts the applicant and reviews project details, documents and load details.
  3. Pay an engineering advance if the Job Owner says one is required.
  4. Express Connect only: PG&E performs a load assessment; if existing infrastructure is insufficient the project moves to the standard New Project process.
  5. Field meeting or job-site walkthrough if necessary.
  6. Engineering and design: PG&E reviews load requirements and system capacity, confirms meter location and service route, prepares construction drawings and a cost estimate.
  7. Review PG&E's construction documents, then sign and pay the contract (Your Projects or DocuSign); complete any easements or land requirements the Job Owner directs.
  8. Site readiness: customer completes required trenching and site work (call 811 before digging) and any agency or PG&E inspections; a new account is set up if the location has not previously had PG&E electric service.
  9. Schedule PG&E construction with the Job Owner; PG&E crews perform the work.
  10. Arrange for the local government agency to inspect the electric panel; once it passes, contact PG&E to schedule the meter connection (meter set and energization).

What PG&E asks for

  • Project scope and timeline
  • Blueprints or plans (floor plans, line drawings, site plans)
  • Load requirements / load sheets, including appliances or equipment to be installed
  • Photos (listed for Express Connect)
  • Permits, if applicable
  • Meter panel details such as rating, UL listing and location (exterior wall, readily accessible, 36 inches of clear working space)

Our ADU electrical plans include the NEC Article 220 load calculation, panel schedule and single-line diagram, which cover the load and equipment information on this list. Site-plan and service-location details come from your architectural set.

A separate meter for the ADU

PG&E offers 'adding a meter and/or service' for an ADU as a residential project type (Express Connect up to 320 amps, or the New Business 'Residential add meter' type). Electric Rule 18 states PG&E will furnish and meter electricity to each individual residential dwelling unit (with listed exceptions), and that, consistent with Gov. Code 66338, junior accessory dwelling units (JADUs: no more than 500 sq ft and contained entirely within a single-family residence) are not considered residential dwelling units and are not required to be separately metered or to have a separate address. The Greenbook says that when more than two dwellings or buildings (e.g., a primary home and ADUs) are on one lot, applicants must consult their PG&E Job Owner on acceptable service-termination and meter locations before wiring, and that PG&E normally provides one service per enterprise, premise or parcel, with listed exceptions.

Whether a separate meter makes sense depends on the load calculation, the existing service size and the cost of the utility work. See when a separate service is required instead of a subpanel.

Service requirements

Meter location, clearances and service equipment must follow Greenbook - TD-7001M Electric & Gas Service Requirements (2026 edition; publication 04/22/2026, effective 06/22/2026). We show the meter and service equipment on the electrical plan so the location can be confirmed with PG&E early.
