The Impact of Installing EV Chargers in Condominiums

The Impact of Installing EV Chargers in Condominiums​

The installation of electric vehicle (EV) chargers in mid- and high-rise condominiums presents significant challenges and risks for the entire building. These buildings typically have an electrical service designed to meet the demands of their time, not anticipating future increases. The introduction of high-demand appliances like EV chargers can lead to a series of issues that affect both individual unit owners and the entire homeowner association (HOA).

Electrical Capacity and Demand​

Condominium buildings are designed to accommodate the electrical load anticipated at the time of their construction. When unit owners start installing EV chargers, the electrical demand significantly increases. Unlike individual condominium unit panels, EV chargers are connected to the main electrical service of the building, typically located in common areas such as parking garages or outside parking lots. This central connection places a considerable additional load on the building’s electrical system.

Electrical Service and Wiring Upgrades​

Most existing electrical systems in condominium buildings are not designed to handle the additional load of multiple EV chargers. This often necessitates upgrades not only to the main electrical service but also to the wiring that feeds the parking garage or lot. Buildings often need to upgrade their entire electrical service to accommodate the increased demand from EV chargers. This process requires detailed planning and possibly multiple permits, as work will be conducted in common areas.

Load Calculations and Permits​

The installation of EV chargers demands detailed electrical load calculations for both the main electrical service and the building's overall electrical capacity. The local Building Department will require these calculations to ensure that the main electrical service and the feeders to the parking areas can handle the increased load. This creates a domino effect, as adding one high-demand appliance impacts the entire electrical system of the building.

Potential for System Overload​

As more unit owners install EV chargers, the cumulative electrical demand can easily exceed the building's capacity. This can lead to situations where the electrical service feeding the parking areas becomes overloaded, potentially tripping and causing power outages for multiple units or the entire parking area. The first-come, first-served nature of such upgrades can result in inequities, where some owners can install EV chargers while others cannot, potentially affecting property values and creating dissatisfaction among residents.

HOA Challenges​

HOAs face significant challenges when unit owners request to install EV chargers. Allowing such installations can force the HOA to consider expensive upgrades to the entire building's electrical system, a cost that would ultimately be borne by all unit owners. Furthermore, locating these chargers in common areas such as parking garages or outside parking lots adds logistical and management challenges. To prevent these issues, many HOAs have established rules regulating the installation of EV chargers. However, more HOAs need to adopt such regulations to safeguard the interests of all residents.

In Summary​

Installing EV chargers in condominiums can be detrimental and costly for the entire building and its residents. The increased electrical demand, the need for extensive electrical upgrades, and the potential for system overload outweigh the individual benefits of convenient vehicle charging. This one-sided opinion underscores the importance of comprehensive HOA rules to regulate the installation of EV chargers, protecting the community from significant financial and operational burdens.
 
Illinois public act 103-0053

"EV-capable" means parking spaces that have the electrical
panel capacity and conduit installed during construction to
support future implementation of electric vehicle charging
with 208-volt or 240-volt or greater, 40-ampere or greater
circuits. Each EV-capable space shall feature a continuous
raceway or cable assembly installed between an enclosure or
outlet located within 3 feet of the EV-capable space and a
suitable panelboard or other onsite electrical distribution
equipment. The electrical distribution equipment to which the
raceway or cable assembly connects shall have sufficient
dedicated space and spare electrical capacity for a 2-pole
circuit breaker or set of fuses. Reserved capacity shall be no
less than 40A 208/240V for each EV-capable space unless
EV-capable spaces will be controlled by an energy management
system providing load management in accordance with NFPA 70,
shall have a minimum capacity of 4.1 kilovolt-ampere per
space, or have a minimum capacity of 2.7 kilovolt-ampere per
space when all of the parking spaces are designed to be
EV-capable spaces, EV-ready spaces, or EVSE-installed spaces.

Okay, then -- Level 2.

Thanks.
