Washington, D.C., has joined the growing list of cities that are requiring new buildings to include EV parking in their plans.

As reported by Smart Cities Dive, new and refurbished commercial and multi-unit buildings in Washington, D.C., that have at least three off-road parking spaces will be required to make at least 20% of those spaces available to accommodate electric vehicle (EV) charging infrastructure, under a new law that took effect this year.

The new requirement came in response to public concern that families in apartment buildings or without garages did not have access to EV chargers, a barrier to purchasing a car. The make-ready rule is part of the city’s goal to have at least 25% of new vehicles registered by 2035 be zero-emissions. Similar make-ready requirements have been adopted or introduced over the past year in cities including Orlando, Florida, Pittsburgh and Salt Lake City as part of a broad effort to increase EV access.
