Commercial EV charging is no longer a perk — it is infrastructure your tenants, employees, and customers expect. Houston commercial property owners who installed chargers in 2022 are seeing higher lease-up rates, longer tenant stays, and real revenue from session fees. Those who wait are competing for tenants with a visibly shorter amenity list.
At Solivance Electric LLC, we design and install commercial EV charging systems across Houston, Cypress, Katy, and Memorial. This guide covers what property owners actually need to know before calling for a quote.
Level 2 vs DC Fast Charging — Which Fits Your Property?
The right charger type depends entirely on how long cars sit at your property.
Level 2 Charging (7–19 kW)
Level 2 is the workhorse of commercial EV charging. It uses standard 208V or 240V power, delivers roughly 20–30 miles of range per hour, and costs a fraction of DC fast equipment. It is the right answer for:
- Office buildings and workplaces (8-hour dwell)
- Apartment and condo parking (overnight dwell)
- Hotels, gyms, and long-dwell retail
- Fleet yards with overnight parking
DC Fast Charging (50–350 kW)
DC fast chargers deliver 100+ miles of range in 20 minutes, but they run on 480V three-phase power, require significant service capacity, and cost 8–15x more per port than Level 2. They fit:
- Highway-adjacent convenience retail
- Fleet depots with short turnaround
- Quick-turn retail (grocery, pharmacy, drive-thru)
- Dedicated public charging plazas
Site Assessment — What We Look At First
Before we quote a single port, we walk the site and collect:
- Existing service capacity. Size of the main service, panel schedule, and existing peak demand.
- Charger locations. Distance from panel to parking, trenching or conduit requirements, accessibility, and future expansion.
- Utility service. Whether the transformer on site can support added load, or whether a utility upgrade is required.
- ADA, signage, and code compliance. Required accessible stalls, clearance, signage, and local amendments.
Load Calculation — The Step Most Contractors Skip
The biggest mistake we see on commercial EV projects is contractors quoting charger installs without running a real NEC Article 220 load calculation. That is how buildings end up with nuisance trips six months later, or with a stranded panel that cannot support anything else.
A proper load study looks at existing metered demand over 12 months, applies the correct diversity factors, and confirms whether load management (which throttles charger output during peak building load) can keep you under service capacity. Many commercial buildings can add four to eight Level 2 ports without upgrading the main service when load management is deployed correctly.
When the calculation shows the service cannot support the planned load, the honest answer is a panel upgrade alongside the chargers. We build that into the quote rather than discovering it mid-install.
Permitting — What to Expect in Houston
Every commercial EV charger install in the City of Houston, Cypress, Katy, and Memorial requires an electrical permit and inspection. On DC fast-charging projects, you will also coordinate with CenterPoint on service size and transformer capacity, which can add weeks to the timeline.
We file the permit, schedule the inspection, and handle any utility coordination. The only thing we ask of the property owner is access and a decision on charger model and networking.
ROI and Tenant Attraction
The financial case for commercial EV charging looks like this:
- Tenant attraction and retention. Surveys from major commercial brokers consistently show EV charging in the top five amenities prospective tenants ask about.
- Session revenue. Networked Level 2 ports in Houston commonly bill $0.20–$0.40 per kWh, netting $200–$600 per port per month in high-use workplace and multifamily settings.
- Federal tax credit. The Alternative Fuel Vehicle Refueling Property Credit covers up to 30% of installed cost (subject to eligibility and location).
- Lease differentiation. Commercial properties advertising EV charging lease faster and support modestly higher rents in competitive submarkets.
Cost Range — Houston Market, 2026
Real installed pricing for commercial properties in our service area:
- Single Level 2 port (wall-mount): $1,800–$3,500 installed
- Dual-port Level 2 pedestal, networked: $4,500–$8,500 installed
- 4-port Level 2 installation with load management: $15,000–$28,000
- Single DC fast charger (50–150 kW): $45,000–$120,000+ installed
Costs vary with trenching distance, panel work, utility requirements, and charger model.
Start With a Site Assessment
The cheapest way to get to a real number on your project is a one-hour site walk with an electrician who installs commercial EV chargers for a living. We will tell you honestly whether your building needs a service upgrade, how many ports it can support, and what the all-in number looks like.
