What that means for a Farmington install
With about 54% of homes built in 2000 or later, many Farmington installs are a short run from a modern panel to the garage. A load calculation still matters if you also have central AC, an electric range, a hot tub or a second EV.
- Newer Farmington homes usually have an attached garage with the panel on a shared wall, the easiest and least expensive kind of Level 2 install.
- Older homes closer to downtown Farmington and up toward the bench are more likely to need a load calculation, or a load-management device, before adding a 40- to 60-amp circuit.
- Many Farmington subdivisions have HOAs. A garage-mounted charger rarely needs approval, but an outdoor pedestal or a charger on the front of the house may.
Across Davis County, 7,660 battery-electric vehicles were registered as of February 2026, and Farmington accounts for about 12% of them.[2]
Charging costs on Rocky Mountain Power in Farmington
Most Farmington 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 Farmington 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.

Farmington EV charger FAQ
Is a Level 2 charger worth it if I live near Station Park and there's public charging?
Public charging is convenient, but home charging overnight on Rocky Mountain Power's time-of-use off-peak rate is typically far cheaper per kWh than public Level 2 or DC fast charging.
Does my Farmington HOA need to approve a charger?
It depends on your CC&Rs. Inside the garage, usually not; on an exterior wall or a pedestal, check first.
Is there an EV charger rebate in Farmington in 2026?
There's no utility rebate for a home charger right now. Rocky Mountain Power removed its residential charger rebate effective Jan. 1, 2026, and the federal 30C credit ended for chargers placed in service after June 30, 2026. See our 2026 rebate guide for what's still available.
