Full Breakdown
Montgomery County Code Chapter 59, the Zoning Ordinance, ties the EV-ready requirement to site plan and building permit review administered by the Department of Permitting Services. Section 59.6.2.5.F sets the design standard: each EV-ready space must be at least 9 feet wide, located in a highly visible, preferential spot in the lot, and wired with conduit and an electrical room sized for a future 120-volt charging station. The mandate applies to new multifamily, commercial, and mixed-use parking facilities built after May 12, 2014 with 100+ spaces, it does not apply inside Rockville, Gaithersburg, Poolesville, Brookeville, Laytonsville, Barnesville, or Washington Grove, which run their own zoning codes.
Violations & Fines
Violating Chapter 59 is punishable by a civil fine up to the maximum allowed under the Maryland Land Use Article; each day the violation continues counts as a separate offense (§ 59.7.8.1).
