EV Charging Site Assessment Checklist for Property Managers

Before your board approves a single dollar for EV charging, a site assessment is the most important step you can take. A thorough assessment reveals what your building already has, what it needs, and — critically — how much the full project will actually cost. Skipping this step is the single most common reason EV charging projects go over budget.

A site assessment typically takes one to three hours and is conducted by a licensed electrician or a specialized EV charging installer. Many installers offer it for free or for a nominal fee that's credited toward the final contract. Bring the assessment report to your board meeting before any vote — it transforms a vague conversation into a concrete decision.

Think of the assessment the same way you'd think of a home inspection before buying a property. You wouldn't close without knowing the roof condition; don't commit to an EV project without knowing your electrical capacity.

The electrical panel is the starting point for any site assessment. The assessor will check your main service capacity (measured in amps), document the available spare circuit breakers, and determine whether your current panel can support EV charging without an upgrade.

Most Level 2 chargers draw between 40 and 80 amps each. A building with 10 parking spaces and a plan to install 10 chargers might need 400 to 800 amps of additional capacity — before any load management software is applied. Smart load management systems can dramatically reduce that number, which is why the assessor should also document whether your building's electrical system is compatible with dynamic load balancing.

Once the electrical picture is clear, the assessor will walk the parking area to understand the physical constraints of installation. The layout determines how much conduit and trenching is needed — two costs that are easy to underestimate if you're working from a floor plan alone.

For surface parking lots, the assessor will look for the most direct conduit pathway from the electrical room. For parking garages, they'll evaluate the ceiling clearance, column spacing, and whether chargers can be wall-mounted or need pedestal-mounted units. Underground or enclosed parking adds fire code and ventilation considerations that must be addressed before finalizing a layout.

Your local utility company has its own requirements for EV charging installations — and its own timeline. Many utility interconnection reviews take four to twelve weeks, so understanding what's required early is essential for planning your project schedule.

The assessor should identify your utility, check for any existing make-ready programs (where the utility installs and pays for wiring upgrades), and note the meter configuration for your building. If your building has a single master meter, you'll need to decide how to handle billing: pass costs through association fees, install a separate submeter for EV circuits, or use a charging network that handles billing directly with residents.

Every EV charging installation requires a permit from your local building department, and the permit requirements vary by city and state. A good assessor will flag the major code considerations upfront so there are no surprises in the permitting process.

The National Electrical Code (NEC), specifically Article 625, governs EV charging equipment installations nationwide. Local jurisdictions may adopt additional requirements or amendments. In parking garages, NFPA 88A (Standard for Parking Structures) addresses ventilation and fire suppression requirements that affect where chargers can be placed and how many are allowed per zone.

ADA compliance under the Americans with Disabilities Act requires that EV charging spaces meet the same accessibility standards as regular accessible parking — proper dimensions, slopes, and connection to an accessible route. Plan for at least one ADA-compliant charging space from the start, even if you're installing just a handful of units.

Once you have the written assessment report, the next step is translating its findings into a phased action plan your board can approve. Most assessments will reveal that a full build-out is feasible but that the upfront electrical infrastructure cost is the largest variable.

Use the assessment to request at least two to three competitive bids from licensed EV charging installers. Each bidder should receive the same assessment report as a baseline so bids are comparable. Be wary of bids that don't address electrical panel upgrades, utility coordination, or permitting fees — those line items rarely disappear, they just show up later.

Finally, review which incentive programs apply to your building. The federal 30C tax credit covers 30% of installation costs up to 100,000 dollars per property. Many utility companies offer additional make-ready rebates that can cover wiring upgrades entirely. A thorough assessment gives you the information you need to claim these programs correctly — and to walk into your first contractor meeting knowing exactly what you're buying.
