Things You Should Consider Before Installing an EV Charger at Your Home

Owning eclectic vehicles is a big deal. They provide countless benefits and advantages. However, you get slightly bound when the car’s charging is involved. EV cars use an electrical cord to charge the same way as they dispense energy.

You can install an EV charger in San Jose homes and be good to go. This may sound good initially, but it can be a huge hassle. There are many important factors to consider when installing an EV charger in a home or private space, and we are unveiling them all in this informative blog.

Permits and Regulations 

According to the government of San Jose, For installing an EV charger in San Jose homes, the regulations and permit requirements vary based on the property type:

  1. Single-Family/Duplex Properties:
    • Level 1 Chargers: No permit needed unless installing a new 120v outlet, which requires an electrical permit.
    • Level 2 Chargers: Both electrical and, if specified by the manufacturer, mechanical permits are required. Plans are not necessary for the permits.
    • At inspection, provide information on UL listing number, panel rating, charging load, circuit size, possible second meter, and the location of the utility panel and EV Supply Equipment (EVSE)​​.
  2. Multifamily Properties:
    • Assigned Parking Spaces: Obtain a permit using Over-the-Counter (OTC) plan review service.
    • Common Areas/Public Housing Facilities: Follow the process for Commercial/Industrial Properties​​.
  3. Commercial/Industrial Properties:
    • Submit plans for building and electrical permits.
    • The process depends on whether the installation exceeds 80% of panel/system capacity.
    • A Permit Adjustment from the Planning Division may be required​​.
  4. Plan Requirements:
    • Electrical plans must comply with the 2022 California Electrical Code and San José Municipal Code, including load calculations and overcurrent protection.
    • Site plans should address grading, drainage, landscaping, lighting, accessibility, and equipment anchorage​​.

Installation Site and Charging Speed

The next important factor is deciding where the installation will be placed. It has to be a place away from things that could alter or damage the flow of electricity to your charger. While you may prefer to place it near the car and garage, outdoor spaces may require weatherproofing to protect the charging site.

Moreover, there are charger levels that can help you determine the total mileage your EV can give. Charging speed has level 1 with a slower pace, while Level 2 has a better speed and more impressive results for the users. 

Electric Capacity

Another important factor you must confirm before purchasing an EV is how much electrical capacity your home has. The connection in your home must comfortably support and supply the EV without obstructing the rest of the flow.

Level-2 chargers require at least 40 amps and 240 volts to function properly. Ensure your panels can support that on top of the other components without faults and hindered supplies. If unsure, take an electrician’s help to assess and gauge the overall capacity.

Professional Assistance 

Professional EV charger installers may be a little costly, but they are worth the price. An expert has all the knowledge and types of equipment to not only collect your requirements, build a plan, and provide suitable suggestions. Alternatives can also be provided based on any issues that need addressing. Professionals are more equipped to perform the task successfully and ensure task safety and maintenance. 

Cost and Expenses

Your budget associated with the car itself is a different thing. But the installation charges are an added factor you must consider beforehand. It’s not a one-time thing. After placing it, the charger will need an active electrical supply to keep functioning. That means your electricity bills will spike a bit, and the management expenses for smooth running will also need to be considered. 

Smart Features and Cord Length 

Understand the smart charging features of your EV and how compatible they will be with your routine and usage. This could include sensors, fast charging, sustainable features, etc.
Moreover, get a charging cord with enough length to charge your car from the supply point comfortably. Any obstacles affect charging quality and overall security.

Be careful with the EV’s warranty. Every part of the vehicle has a distinct purpose and can be utilized to its full potential, but there is a limit to how long it can go in the given environment. Pay attention and don’t overutilize the EV and its parts more than they have been suggested. 

Access Control and Safety

EV chargers aren’t secure enough to be used carelessly. Ensuring that an aware user controls them can prevent accidents and prolong safe usage. Given the instructions or the installer’s directions, you must operate everything carefully and stick to the conditions required for longevity and security. 


Like every other vehicle, EVs require optimal maintenance. Therefore, you must often check your charger, installation site, and more factors to ensure everything is clear. In case of minor issues, contact the manufacturer or an expert to resolve them soon. If left unattended, they might become a more expensive problem.
