EV-ready: ≥ 50-A dedicated 240-V circuit OR conduit + breaker space to garage parking; one space per dwelling

Description

ZERH-certified homes must include EV-charging readiness: AT LEAST one parking space served by either (a) a fully-installed Level-2 EV charger or (b) a dedicated 240-V, 50-A circuit + receptacle at the parking space, OR (c) a 1-in conduit from the main panel to the parking space + dedicated breaker space + service capacity. The conduit path must be labeled 'EV Charger' inside the panel.

Why this exists

Same logic as PV-readiness — retrofitting a 50-A charger to a finished garage costs $1500-3000 in electrical + drywall; routing the conduit at framing is $100. Architects designing for ZERH (or any future-oriented home) should make this a standard part of garage electrical.
