Broomfield, CO Parking Rules: EV Charging (2026)

Table R409.5.3.1, amended by § 15-07-010(D), sets tiered electric-vehicle infrastructure requirements by building type and parking-lot size. For Group R-3 and R-4 occupancies of three stories or less with fifteen or fewer parking spaces, no EVSE-installed spaces are required but 20 percent of spaces, and never fewer than two, must be EV-ready. Once such a building exceeds fifteen spaces, 2 percent must be EVSE-installed (charger already in place), 8 percent EV-ready (wiring in place, charger pending), and 10 percent each EV-capable and EV-capable-light (conduit only).

Group R-2 apartment buildings face steeper numbers: those with ten or fewer spaces need 10 percent EVSE-installed and 15 percent EV-ready, and those with more than ten spaces need 5 percent EVSE-installed, 15 percent EV-ready, 10 percent EV-capable and 30 percent EV-capable-light. A parallel commercial table, C410.5.2.1 under § 15-07-010(H), applies the same tiered structure to non-R-2 commercial buildings. Builders must show the required spaces, and the conduit routing that serves them, on construction documents submitted with the permit application under § 15-03-080(A)(8)-(9), and the building official verifies compliance before a permit issues.
