5 tips to know before installing multi-family EV charging

During the first half of 2021, electric vehicle (EV) sales surged in all three major markets — the United States, Europe, and China, according to Power Technology. From the prior year, sales increased 160% to 2.6 million units. The growth in electric vehicle sales supports increased demand for EV charging stations.


88% of electric vehicle charging happens at home, according to a J.D. Power survey. Typically, charging occurs in single-family residences with dedicated parking, where EV charging station installation is fairly straightforward.


According to America’s Rental Housing 2020 more than one-third of Americans are currently renting their homes. Likewise, many multi-family properties are missing on-site EV charging stations, hindering EV adoption. That barrier also impacts owners who live in multi-unit dwellings (MUDs) such as apartments and condominiums.


For example, California is one of the highest contributing states for EV infrastructure in North America, with 50% market share of EV sales in the United States. However, among the 90% of EV charging equipment in homes, only 18% are stationed in multi-family housing. “Right to charge” laws require a portion of parking in new MUDs to include EV charging stations. However, installing EV charging in existing multi-family properties can be challenging without proper guidance.


Nevertheless, apartment and condo dwellers will increasingly expect communities to provide EV charging. This expectation benefits properties as EV charging can help attract and retain residents, raise property values, and increase brand value in competitive markets. Below are 5 things to consider as a property owner when choosing multi-family EV charging stations.


Designated versus community parking spots

“For existing buildings, equitable access to charging stations remains the biggest challenge,” said Andrew Croll, Senior Director of Commercial Sales, Enel X Way e-Mobility. Access depends mainly on the distance from parking spots that need EV charging to the electrical panel. MUDs generally apply two approaches:


  • Designated charging: At these properties, each resident has a dedicated parking spot. But if EV owners are spread throughout a parking garage, installing charging infrastructure can prove difficult — from pulling the wire and running conduit to permitting and conducting coring studies.
  • Community charging: In other complexes, select spots are dedicated to EV charging stations. This configuration lets MUDs put charging stations close to the electrical panel and keep construction costs down.


A final consideration is whether charging stations can be wall-mounted, which saves money on electrical prep work, instead of pedestals requiring running conduit through landscaping, asphalt, and sidewalks.


Paid or free charging

You must also decide whether to bill for EV charging. Before COVID-19, electric vehicle charging stations in MUDs weren’t used much until residents arrived home from work, usually during times when electricity prices were lower. However, demand for charging has changed with today’s home and office hybrid working models.


If MUDs want to recoup the higher kilowatt-hour costs for charging during the day, they need smart charging stations to calculate electricity usage and pricing. Smart charging features like those of the Enel X Way JuiceBox Pro also help manage costs. For example, in Los Angeles, utility rates are highest from 2-5 pm in the summer. Load balancing lets properties sync power consumption with utility rates. During the afternoon hours, a MUD may want 40-amp charging stations to dispense only 6 amps until the price drops later in the day.


In addition, the ability to access state and/or utility incentives typically requires “smart” network-connected chargers that collect data and analyze usage, which helps utilities better integrate EVs and renewables into the grid and lower demand.


EV-ready or make-ready infrastructure

For multi-unit dwellings built without EV charging infrastructure in mind, a limited electrical supply may create a constraint when planning charging stations. That limitation can be critical if a MUD decides to provide dedicated EV charging at every parking spot. Load balancing can help solve this problem.

Load balancing lets MUDs group multiple EV charging stations on a single circuit. By capping the amount of electricity pulled at any moment, load balancing eliminates the need for additional electrical wiring. At the Sage Condominiums in Phoenix, AZ, the Enel X Way JuiceBox’s load balancing feature lets the electrician install up to three EV charging stations on a single circuit, saving thousands of dollars in electrical costs.


Level 1, 2, or 3 charging

While more than 15 states now have building codes that require the installation of EV charging stations, multi-family property owners have a choice between three levels of charging, as shown below.





Multi-family property owners generally choose Level 2 chargers due to their charging time, size and cost.


Incentives versus rebates versus credits

Multi-family property owners can pay far less for EV charging equipment, installation and/or make-ready costs by taking advantage of billions of dollars in federal, state, and utility incentives.


The federal government offers a tax credit for EV charging hardware and the cost of installing it. The credit covers 30% of the cost, with a maximum of $30,000 for commercial installations. The credit covers 30% of the cost, with a maximum of $30,000 for commercial installations. Note that starting January 1, 2023, installations must meet specific census tract requirements to qualify, such as being located in a low-income or non-urban area. Many states offer incentives, which can cover from 50% to 100% of the total project costs, including the EV charging station and electrical infrastructure and installation.


Some of the most lucrative commercial incentives come from utilities with established EV charging programs. “Utilities are the drivers for rebates because they want drivers filling up on kilowatt-hours as opposed to gallons of gasoline,” said Croll. Given the urgent need to make charging stations more accessible in MUDs, many of these programs offer extra incentives for multi-family properties.


Incentive eligibility is often dictated by the zip code where you’re installing charging stations. Property managers need a savvy partner like Enel X Way to help them sort through incentives and identify the best programs for them.

Bonus tip: Start now

Do your due diligence on EV charging, including getting quotes on the scope of work you have in mind. This way, you’ll be ready to take immediate advantage of an incentive when it becomes available.
