Electric Vehicle Supply Equipment Permitting & Inspection Guidelines

Guidelines that provide an overview of code requirements for the installation of Electric Vehicle Supply Equipment in single family, multifamily, and office buildings.

In many parts of the United States, navigating building permits required for distributed energy resources such as solar, storage, and electric vehicles (EVs) can be a daunting process.  Under a three-year project, funded by the Department of Energy, the New Buildings Institute (NBI; an EMPOWERED partner) has led the development of a series of guidelines to streamline the permitting and inspection processes for distributed energy resources to reduce carbon emissions, save people money, and help balance energy supply and demand on the grid.

These guidelines provide an overview of code requirements for the installation of Electric Vehicle Supply Equipment in single family, multifamily, and office buildings. By providing specific and replicable lists of permitting and inspection requirements, local jurisdictions can streamline the permitting and inspection process by reducing informational barriers while helping ensure the design and installation of these distributed energy resources are consistent, code compliant, and safe.

In 2023, NBI will pilot these guides in several jurisdictions across the country to refine their content.

We’d appreciate any feedback on these guidelines that you would be willing to provide on these resources by filling out the questionnaire below:

Single Family Guidelines

These guides provide an overview of code requirements for the installation of Level 2 Electric Vehicle Supply Equipment (EVSE) installations and 120V or 240V outlets in single family buildings. The guides reference the 2020 NEC and 2017 NEC, download the respective versions below. 

Multifamily and Office Guidelines

These guides provide an overview of code requirements for the installation of Level 2 Electric Vehicle Supply Equipment (EVSE) installations and 120V or 240V outlets in Multifamily and Office buildings. The guides reference the 2020 NEC, 2021 IBC and 2017 ICC A117.11 as well as the 2017 NEC 2018 IBC and 2017 ICC A117.11, download the respective versions below.
