Can You Install an EV Charger in Your Garage in Mojave?
For most Mojave homeowners, the garage is the obvious first choice for an EV charger location — and in most cases, it's the right one. It offers weather protection, overnight charging convenience, and typically puts the charger closest to the electrical panel, which simplifies the wiring run and keeps installation costs down.
But "the garage works" doesn't mean the installation is automatically simple. Adding a Level 2 EV charger to a garage means adding a high-demand dedicated circuit to your electrical system — and whether that's straightforward or requires additional work depends entirely on your panel's current capacity and condition. Permits are also required, and in Mojave, those go through Kern County rather than LA County.
Bolt Blitz Electric, a licensed C-10 electrical contractor serving Mojave and surrounding areas, regularly installs EV chargers in residential garages throughout the high desert. Here's what you need to know before getting started.
Why the Garage Is the Most Practical EV Charger Location
Garages are the most common EV charger location in Mojave homes for good reason. The combination of practical advantages typically makes garage installations more cost-effective and more convenient than any alternative location.
Weather Protection
Mojave's extreme heat, dust, and occasional high winds are hard on outdoor electrical equipment. A garage installation protects the charger unit and its wiring from the conditions that shorten the lifespan of exterior installations.
Overnight Charging Convenience
Parking inside the garage overnight and plugging in before bed is the ideal daily EV charging routine — the vehicle is fully charged every morning without any additional effort.
Shorter Wiring Runs
In most Mojave homes, the electrical panel is located in or adjacent to the garage. Shorter distances between the panel and the charger mean less wiring, less conduit, and lower installation cost.
Secure and Accessible
A charger inside the garage is protected from unauthorized access and visible damage. It's also accessible for maintenance and inspection in a way that exterior or carport installations sometimes aren't.
Electrical Requirements for Garage Installation
Installing a Level 2 EV charger in a Mojave garage requires adding a dedicated 240-volt circuit from the electrical panel to the charger location. This is true regardless of where the charger is installed — but the garage's proximity to the panel often makes this the most efficient route.
Per NEC Article 625, EV chargers must be installed on a dedicated circuit — no other loads share the breaker or wiring. Per NEC Article 210, EV chargers are classified as continuous loads and must be calculated at 125 percent of their rated current when sizing the circuit. In practice, this means the most common circuit configurations are 40-amp, 50-amp, and 60-amp dedicated circuits depending on the charger's output rating — with the breaker and wiring sized to match.
Does Your Panel Have Enough Capacity?
Before any wiring is run, the electrical panel must be evaluated to confirm it can support the new dedicated circuit. Per NEC Article 220, a load calculation accounts for all existing circuits and their usage to determine how much remaining capacity is available. If the panel has sufficient headroom, the installation proceeds directly. If the panel is at or near capacity — which is common in older Mojave homes that were originally built with 100-amp service — a panel upgrade or subpanel installation may be required before the EV charger circuit can be safely added.
This evaluation isn't a formality — it's the step that determines whether your installation is a straightforward single-day project or one that requires additional work and coordination before the charger can go in.
Garage Installation Considerations
Even when the garage is clearly the right location, several installation factors affect how the work is planned and executed.
Key Factors That Affect Garage Installation
- Distance from panel to charger location — the closer the charger mounts to where the panel is located in the garage, the shorter the wiring run and the lower the material and labor cost. Even within the garage, placement on the wall closest to the panel makes a meaningful difference.
- Wall and mounting conditions — the charger must be mounted securely to a wall surface that can support the hardware. Per NEC Article 110, electrical equipment must be installed in a suitable, accessible location. Hollow drywall without backing may require additional support before mounting.
- Conduit requirements — in a garage where wiring runs along exposed wall surfaces rather than through finished walls, conduit is used to protect the conductors. The routing of that conduit affects both the appearance of the finished installation and the labor involved.
- Clearance and ventilation — the charger should be positioned with adequate clearance from stored items, vehicles in the garage, and heat sources. A well-chosen mounting location avoids these conflicts and keeps the charger accessible for daily use.
- Charging cable reach — the charger needs to be positioned close enough to where the vehicle parks that the charging cable reaches the charge port comfortably without being stretched across the garage floor or requiring the vehicle to park in an awkward position.
Permits Required for Garage EV Charger Installation in Mojave
Installing an EV charger in your Mojave garage requires a permit — because the work involves installing a new 240-volt circuit, adding a breaker to the panel, and running wiring that must be inspected before being put into service. This applies to garage installations just as it does to any other location.
Mojave is in Kern County, which means permits are processed through the Kern County permitting system rather than the LA County EPIC-LA system used in other parts of Bolt Blitz Electric's service area. This is an important detail for homeowners planning the timeline, as the permit process and scheduling work differently between the two counties.
Permit Processing for Mojave:

After installation is complete, a Kern County inspector verifies proper breaker sizing for the continuous load, safe wiring installation throughout the circuit run, correct grounding and bonding, and full compliance with the California Electrical Code. This inspection closes the permit and confirms the installation is approved. Work done without permits has no such verification — and unpermitted electrical work creates liability issues that surface during home sales and insurance reviews.
SCE and Utility Considerations
In some Mojave garage EV charger installations, Southern California Edison involvement is required — specifically when the panel evaluation identifies that a service capacity upgrade is needed alongside the panel upgrade. This is most common in homes with 100-amp service where the new EV charger load, combined with existing household loads, exceeds what the current service can support even after a panel replacement.
When SCE involvement is needed, it adds both time and a coordination step to the overall project. Your licensed electrician handles this coordination, but the utility's scheduling timeline is outside the contractor's control and should be factored into planning when a service upgrade is identified as a possibility.

EV charger installation involves 240-volt high-demand electrical work — the same voltage used by electric dryers and ovens, but drawing current continuously for extended periods during every charging session. While the physical mounting of the charger unit might seem manageable, the circuit work behind it involves real risk when done incorrectly and is regulated for that reason.
In California, EV charger installation must be performed by a licensed C-10 electrical contractor. DIY installation of the electrical components creates several compounding problems: the work won't pass the required inspection, the permit cannot be closed, the installation is unpermitted and creates liability, and the safety risks of improperly terminated high-voltage connections are genuine. The installation also won't qualify for most rebate and incentive programs, which require licensed contractor installation as a condition of eligibility. The cost of having an unpermitted installation corrected and brought into compliance almost always exceeds what professional installation would have cost from the start.
