EV Charger and Robotaxi Charging Installation in Houston, TX

Houston's public network is unusually fast-heavy: 639 of its 1,585 ports, about 40%, are DC fast in AFDC data pulled Oct 14, 2026, so Level 2 at workplaces and apartments is where the gap is.

Medical Center staff garages, Energy Corridor campuses and Galleria-area apartments need Level 2. Fast charging fits fleets near the Port of Houston and the airports, plus retail along the beltways where drivers stop briefly.

Our general Houston EV charging station installation guide covers the service; here are the city data, the utility setup and the flood and depot planning.

AFDC data from Oct 14, 2026 lists 404 public stations in Houston with 946 Level 2 and 639 DC fast ports.

That is about two fast ports for every three Level 2, a far higher fast share than most large cities. Long drives and large retail lots favor quick stops, but apartments and offices still have too few Level 2 ports for all-day parking.

The EV charging ports database tracks Houston's count month by month.

The 404 stations average 3.9 ports. The fast-charging share reflects big highway and retail sites; residents of apartments without assigned spaces still have few Level 2 options near home.

CenterPoint Energy delivers the power and no commercial charger program is listed; owners buy energy from a retail electric provider.

As in Dallas, the ERCOT split means a service request with CenterPoint and a rate chosen from a retailer. Fleet sites often benefit from plans with cheap overnight energy.

Many Houston owners also ask about backup power after long storm outages; we can plan space for batteries or a generator, priced separately.

The Houston Permitting Center targets 15 business days for commercial review; NEC Article 625 sets the wiring rules and the U.S. Access Board the accessible-space guidance.

Houston has no zoning, but it does set off-street parking minimums by use in Chapter 26. Converting stalls must keep the count legal, so we check before drawing.

In flood-prone areas, floodplain rules decide equipment height. The accessible charger is placed first.

Houston has no zoning code, but deed restrictions and the city's off-street parking rules still apply, so we read both before converting stalls.

With no CenterPoint rebate, Houston projects use the Texas programs on the AFDC state page and retail time-of-use plans.

Owners here can no longer plan on 30C; the IRS Instructions for Form 8911 end it for chargers placed in service after June 30, 2026.

Fleet leases and tenant demand drive most Houston projects.

With no CenterPoint program, Texas programs on the AFDC page and a retail plan's off-peak pricing are where the savings come from.

Twelve Houston Level 2 ports run about $47,300 to $106,500 installed and four DC fast ports about $197,000 to $592,000, by our estimate.

Houston's BEA index of 98.6 sits slightly under the national average. We scale national per-port costs and AFDC's installation guidance to it; raised pads in floodplains add cost.

Expect roughly 8–16 weeks for a Level 2 job on spare capacity and 26–52 for a fast-charging job with new service, after permits, by our estimate.

Per port, Houston comes to about $3,942 to $8,875 for Level 2 and $49,250 to $148,000 for fast charging at the BEA index, by our estimate. Raised pads in flood-prone areas and soft clay soils add cost; so does waiting on CenterPoint for a new transformer.

Houston chargers run on the same software as our gates: we set session prices, start idle fees after a grace period, watch every port around the clock, enforce charging-only stalls and send a monthly report.

Storm season adds a step: before a named storm we can shut down chargers remotely and inspect them after.

The Houston parking management page covers gates and enforcement; EV charging parking management covers the charging side.

Bush Intercontinental's normals show 111 days a year at 90°F or hotter and a coldest-month low near 44°F. Heat and humidity work on connectors and cooling fans, so we inspect them on a summer schedule and keep spare parts close.

Houston's 639 fast ports lead the table; Austin, about 146 miles west, has 309.

Baton Rouge and New Orleans have their own utilities outside ERCOT, and Austin has a city-owned utility, so Houston's wires-and-retailer setup is shared only with Dallas among nearby metros.

Dallas, about 223 miles north, shares the Texas retail power market but runs on Oncor's wires instead of CenterPoint's.
