Summary
Boston's Zoning Code treats electric vehicle charging as an accessory parking use, but caps it at four Direct Current Fast Charging stations, with no cap on Level 1 or Level 2 chargers. Non-residential lots and buildings with three or more units must reserve one ADA-accessible charging space with an access aisle, prioritized on a use-last basis.
Accessory Electrical Vehicle Charging. Vehicle charging infrastructure accessory to a lawful parking use and including no more than four Direct Current Fast Charging (DCFC) stations or any number of level 1 and level 2 electrical vehicle charging stations as defined by the US Department of Energy. For charging stations associated with non-residential uses or residential uses with three or more units, at least one charger must be provided on a space which meets the size requirements for accessible spaces outlined in the Americans with Disabilities Act (ADA) including an access aisle. This space would be in addition to any fully accessible (non-charger) spaces required by the ADA. For facilities with more than one EV charger, the accessible EV charger space shall follow a "use last" model, including signage, as defined by the U.S. Access Board's Design Recommendations for Accessible Electric Vehicle Charging Stations. Such use shall not be subject to the provisions of Section 8-2.5b.
Full Breakdown
S. Department of Energy, is allowed under the same accessory classification. Below that threshold, ordinary accessory parking already covers chargers on its own: the Article 8 definition of "Accessory Parking" states that parking accessory to a residential use may include up to two electrical vehicle chargers, and that three or more chargers reclassifies the installation as Accessory Electrical Vehicle Charging, pulling in the separate DCFC cap and ADA rules. For non-residential uses, and residential buildings with three or more units, at least one charger must sit on a space meeting the Americans with Disabilities Act's accessible-space and access-aisle dimensions, in addition to any fully accessible non-charger spaces the ADA already requires elsewhere on the lot.
S. Access Board's Design Recommendations for Accessible Electric Vehicle Charging Stations. 5(b), but the Zoning Code expressly exempts Accessory Electrical Vehicle Charging from that area limit, along with Accessory Parking and a short list of other utility-type accessory uses. The Building Commissioner enforces the Zoning Code citywide under Section 5-1.
Violations & Fines
Installing a fifth DCFC station, or skipping the required ADA-compliant, use-last accessible charging space at a qualifying non-residential or multi-unit site, takes the installation outside the Accessory Electrical Vehicle Charging exemption. That can trigger Table A/B use review as a distinct, potentially conditional or forbidden use in the applicable district. The Building Commissioner enforces the Zoning Code under Section 5-1, and noncompliant installations risk a stop-work order or denial of the occupancy or building permit tied to the charging infrastructure.
