ADU Electrical Service with Anaheim Public Utilities
How to get a service upgrade, a new or separate meter, or a relocated service from Anaheim Public Utilities when you add an ADU, and what our electrical plans give you for that application.
Who Anaheim Public Utilities serves
Municipal electric and water utility of the City of Anaheim, California. Of the California places we cover, 1 is served mainly by Anaheim Public Utilities, and together they issued 1,713 ADU building permits from 2021 through 2025.
How Anaheim Public Utilities handles new and upgraded service
Anaheim Public Utilities handles new service, service upgrades and meter changes through its Meter Spot Report process. This is separate from the building permit, so start it as soon as the electrical load calculation shows what the ADU needs. The steps Anaheim Public Utilities describes:
- Call the APU Utility Inspector to request a Meter Spot Report; the inspector visits to confirm the new panel/meter location and sizing meet electric codes and APU standards.
- With the Meter Spot Report and construction plans, obtain a building permit from the City of Anaheim Building Division.
- Construct; the contractor typically installs the panel and customer-side conduit/cable while APU crews install utility equipment (utility cable, transformer, meter) per a service plan from APU's electric designer where needed.
- Call for the building inspection listed on the permit; the Meter Spot Report must be on site at the Building Division inspection for installing, relocating or upgrading a residential service panel.
- Customers reconfiguring the number of services must obtain a building permit and, as necessary, a service plan from the Utility (Rule 16.B.3.b).
What Anaheim Public Utilities asks for
- Meter Spot Report (issued by APU)
- Construction plans for the building permit
- Load calculation by the electrician (the City's checklists state a Meter Spot Report is required when the load calculation calls for an upgrade)
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.
Service requirements
Meter location, clearances and service equipment must follow City of Anaheim Electric Rates, Rules and Regulations, Rule No. 16 (Service Connections and Facilities on Customer's Premises); APU Electrical Engineering Design Manual (rev. 2021). We show the meter and service equipment on the electrical plan so the location can be confirmed with Anaheim Public Utilities early.
