What that means for a Washington Terrace install
With about 69% of homes built before 1980, Washington Terrace is a city where we'd always start with a load calculation. Many homes of that era were built with smaller electrical services, and EV charging is a large, continuous load.
- In homes this age, the right first step is a load calculation. It tells you whether a 32-, 40- or 48-amp charger fits, or whether a panel upgrade or load-management device is needed.
- Smaller lots and single-car garages are common, so an outdoor-rated charger on a driveway-side wall is often the practical choice.
- Washington Terrace is Rocky Mountain Power territory, so the Schedule 1 time-of-use option is available to most homes.
Across Weber County, 3,378 battery-electric vehicles were registered as of February 2026, and Washington Terrace accounts for about 1% of them.[2]
Charging costs on Rocky Mountain Power in Washington Terrace
Most Washington Terrace homes are Rocky Mountain Power customers. RMP's Schedule 1 time-of-use option treats only 6 to 10 p.m. on non-holiday weekdays as on-peak. Off-peak base energy is 6.6111¢ per kWh from October through May and 7.4705¢ from June through September, versus on-peak prices of 29.7498¢ and 33.6173¢.[3] Surcharges and taxes are extra, and the rate applies to your whole home, so it pays off when you can keep big loads out of the evening window.
RMP's Wattsmart Drive program, run through your car maker's app for supported brands, pays up to $100 in bill credits the first year and up to $50 each following year in exchange for letting RMP briefly manage charging.[4] There is no RMP rebate for the home charger itself in 2026.[5] If your bill isn't from Rocky Mountain Power, these programs won't apply.
Permits and inspection
The electrician pulls the electrical permit through Washington Terrace City's building process, and the work is inspected before it's energized. Utah adopted the 2023 National Electrical Code effective July 1, 2025, and most one- and two-family homes follow the electrical provisions of the International Residential Code as amended by Utah.[6][7] Current code requires GFCI protection for many EV outlets; your electrician will confirm exactly what your install needs.
