The manufacturer makes the EV charging station the standard in new homes

The Edison Electric Institute estimates that 26.4 million electric vehicles will be on US roads by 2030 and nearly 12.9 million charging stations will be needed to support them.

Since the most convenient place for most EV owners to charge their vehicle will be at home, builders are beginning to pre-wire or install charging units in new single-family homes.

The International Code Council recommends that new homes be built with charging stations, and building codes requiring EV-ready construction already exist in places like Atlanta, Denver, Seattle and California.

Edmond-based STK Homes announced this summer that an EV-240-volt outlet and wiring will now be standard in every home it builds.

“As cars evolved, we thought this would be a good feature to put in our homes,” said Madi McFarland, the company’s marketing coordinator.

Just as smart home technology to control devices like lights, security and thermostats has become the norm, “we think it will be too,” McFarland said.

As of Sept. 1, the 50-amp circuit needed to support a Level 2 EV charger for a vehicle had been installed in 26 homes, she said.

STK Homes builds homes in the Edmond and Norman areas, as well as Yukon, Kingfisher and Enid. It closed 150 homes in 2021 and has a target of 250 this year.

Home prices range from $200,000 to $700,000, McFarland said. Either way, all will have EV outlets and wiring in the future, she said.

21OAK.com reports that the ICC’s recommendation to include electric vehicle charging capability in residential construction will encourage more homebuilders to install this feature.

A Tier 2 charger can vary in terms of the product itself as well as setup costs, but will typically cost up to $3,500 in total, according to the report.

While most electric cars come with a Level 1 charger included, many EV owners upgrade to a Level 2 charger, which powers the vehicle faster and more efficiently.

Having the necessary infrastructure in place should save owners money, according to the ICC. A study shows that EV-ready homes will cost an additional $920, but adding the electrical work later could cost around $3,550.

McFarland said charging stations are just another way for STK Home upgrades to exceed minimum standards. Every home receives a Home Energy Rating System (HERS) audit to ensure energy efficiency, she said.

“The average HERS score for an STK home is 55. This means that new STK homes are 45% more energy efficient than standard, minimally built homes, which have an average HERS score of 100,” said Jeremiah Bryant of ‘Eco Home Services home energy design and building science company.
