Do I Need a Permit to Install an EV Charger in Colorado?
Quick Answer
Level 2 (240V) chargers yes. Level 1 (120V plug-in) no.
Colorado-specific rules
Colorado's statewide energy floor, HB22-1362 (2022), requires any jurisdiction that adopts or updates a building code between July 1, 2023 and July 1, 2026 to adopt the state's EV-Ready (and electric-ready) provisions on top of a 2021 IECC floor. Electrical permitting and adopted editions otherwise vary by jurisdiction (Colorado is home-rule) — confirm who issues your permit with your city or county.

Level 1 vs Level 2
Level 1 chargers plug into a standard 120V outlet and do not require a permit. Level 2 chargers require a dedicated 240V circuit (usually 40-50 amps) and always require an electrical permit. Level 2 is what most EV owners install for practical daily charging speeds.
Panel Capacity
A Level 2 EV charger draws 40A and requires a 50A breaker. Many older homes have 100A or 150A panels that may not have capacity. If your panel is full, you'll need a sub-panel or panel upgrade ($1,500-$3,000 additional). An electrician can do a load calculation to determine if your current panel can handle it.
Installation Location
Most home EV chargers are installed in the garage, near the electrical panel. Longer runs from the panel to the charger increase wire cost. Outdoor installations require a weatherproof-rated charger (NEMA 4 or 4X enclosure).
Rebates and Incentives
Many utilities offer rebates for residential EV charger installations. Federal tax credits may also apply. Check current programs with your utility before installation — rebates often require pre-approval and may have specific equipment requirements.
Bottom Line
Level 2 chargers need an electrical permit ($40-$75). Fast approval, one inspection. Check for utility rebates first.
