Multifamily EV charging: house load or assigned meters — those are different designs, and the stalls people will actually use
Multifamily EV charging sits on house load or on assigned meters, and those are different designs. Load management, billing, and the existing service decide whether the job is a few assigned stalls or a networked garage.
The garage cannot run every stall at once
Sharing the feeder is commercial EV load management.
A stall that has to be billed
Measurement, not a guess from the house meter, is submetering.
The building service is the limit
House load, unit load, and the utility on one schedule is multifamily service upgrade.
Multifamily EV charging: california expects EV-ready spaces — and every stall needs an owner on the bill
New and renovated multifamily in California carries EV-ready and EV-capable requirements under the building code, and every stall that charges has to land on someone’s bill. The design is a metering and cost question as much as a circuit one.
-
EV-ready by code
CALGreen and Title 24 set how many spaces must be EV-ready or EV-capable in qualifying multifamily. Meeting it at construction is a fraction of the cost of retrofitting a finished garage.
-
House meter or submeter
Charging on the house meter socializes the cost across every tenant; a submeter per stall attributes it. Which one the property wants changes the whole electrical layout.
-
An old garage retrofit
Adding stalls to an existing structure is a panel, a feeder, and often load management before a single charger hangs — the concrete and the conduit are the hard part.
When multifamily EV charging isn’t the right job
Tenant or assigned stalls on a residential property are this job. Employee stalls on a commercial service are not.
It is employee or fleet charging at a workplace
That is workplace EV charging.
You only need to measure the stall
That is submetering.
Multifamily EV charging questions
Can we put it all on house load?
Sometimes. House load that cannot take unmanaged charging is why load management and assigned meters exist. Sharing the feeder is commercial EV load management.
How do we bill the stall?
That is submetering. This job is the stalls, the meters, and the service they sit on.
The board wants twenty stalls next year.
Then the existing service may be the limit. A building increase is multifamily service upgrade — not a stack of house chargers.
Is this the same as workplace charging?
No. Tenants, house meters, and assigned stalls are this job. A workplace lot is workplace EV charging.
