Having a Separate Electric Meter for an ADU
When adding an ADU to a property, some homeowners definitely want to have a separate electric meter, especially if they are going to rent out the ADU. Other homeowners who are going to use the ADU for family members may not have the need for a separate meter, and also may not want to spend additional money to install an additional meter.
Homeowners who want to have a separate electric meter can request this and pay the costs associated with having a separate meter.
However, for homeowners who don’t want to have a separate meter, the situation is more complicated. The homeowner may be able to have just one meter, depending on the following factors:
- The rules of the utility company. Some utility companies (e.g., those in Los Angeles) do not require a separate meter for an ADU unless the owner requests it. However, this is not the case for other utility companies (e.g., PG&E in Northern California.) If the homeowner lives in an area where the utility requires a separate meter, an additional factor must be considered.
- A separate address for the ADU. Some cities do not require a separate address for an ADU and will issue a separate address on request. In these cities, if the homeowner does not request a separate address, then a separate meter may not be required (check with the local utility). However, some cities require a separate address for an ADU. There are two kinds of separate addresses:
- The ADU’s address is the address of the main residence is followed by A, B, or ½. For example, the main house’s address is 2466 and the ADU’s address is 2466A. In this case, a separate meter may not be required (check with the local utility).
- The ADU’s address is an entirely separate number. For example, the main house’s address is 2466 and the ADU’s address is 2468. In this case, a separate meter is required.
