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. I found out that utilities in Southern California do not require a separate meter for an ADU unless the owner requests it. However, this is not the case for PG&E in Northern California. If the homeowner lives in Northern California, an additional factor must be considered.
  • A separate address for the ADU. Some cities require a separate address for an ADU. If an ADU has a separate address, then PG&E recognizes it as a separate residence, and requires a separate meter for the ADU. Other cities do not require a separate address and will issue a separate address on request. In these cities, if the homeowner does not request a separate address, then a separate meter is not required.
