What an EV charger permit costs in Harris County
How to apply in Harris County
In Harris County, in most of the US, installing a Level 2 (240 volt) home EV charger is handled as an electrical permit built around a load calculation and a single line diagram showing the new dedicated circuit. A Level 1 charger that simply plugs into an existing 120 volt outlet typically needs no permit unless new wiring is added.
What most EV charger permit applications include:
- For Harris County, a Level 2 charger needs its own dedicated 240 volt circuit and requires an electrical permit with inspection, since each outlet installed for EV charging must be fed by an individual branch circuit with no other outlets on it (NEC 625.40).
- For Harris County, the application includes an electrical load calculation showing the existing service panel has enough spare capacity for the added EVSE demand, worked out using the standard dwelling load calculation method (NEC 220.83).
- For Harris County, the breaker or other overcurrent device feeding the charger must be sized for continuous duty, rated at not less than 125 percent of the equipment's maximum load (NEC 625.41).
- Plan submittal typically includes a single line diagram showing conductor size, breaker size, conduit, and panel rating, plus the charger's manufacturer specifications, since the EVSE itself must be a listed product (NEC 625.5).
- For charging equipment rated over 60 amps or over 150 volts to ground, the application has to show a disconnecting means installed in a readily accessible location and capable of being locked open (NEC 625.43).
- For Harris County, the charger must be shown connected and fastened in place according to the manufacturer's installation instructions, whether it is hardwired or a plug in unit on a dedicated receptacle (NEC 625.44).

Inspections and closing out your permit
In Harris County, a Level 2 EV charger installation gets a rough wiring inspection if any new conductors will be hidden inside walls, ceilings, or run underground, then a final inspection that checks the dedicated circuit, breaker sizing, any required GFCI protection, the disconnect, and the charger's listing before the permit closes.
- In Harris County: if new EVSE conductors will be concealed in a wall or ceiling, or run underground, they must pass a rough wiring inspection before being covered, since that inspection confirms the dedicated branch circuit required for the charger (NEC 625.40).
- In Harris County: at final inspection, the breaker or other overcurrent device serving the charger is checked to confirm it is properly rated for the continuous EV charging load (NEC 625.41).
- In Harris County: any receptacle installed for EV charging, as opposed to a hardwired connection, has to be checked for ground fault circuit interrupter protection (NEC 625.54).
- In Harris County: where the EVSE is rated over 60 amps or 150 volts to ground, the inspector confirms a lockable, readily accessible disconnecting means was installed (NEC 625.43).
- In Harris County: the inspector verifies the charger, along with its fittings and associated equipment, carries a nationally recognized testing laboratory listing (NEC 625.5).
- In Harris County: mounting height is checked against the manufacturer's instructions, with the coupling means generally required to sit at least 18 inches above an indoor floor or 24 inches above outdoor grade unless the equipment is listed otherwise (NEC 625.50).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Harris County permit portal or by phone at (713) 274-3900.

- Under Texas law (Tex. Occupations Code 1305.003(a)(6), 1301.051; Tex. Local Government Code 233.157(c)): Texas licenses individual construction trades rather than general contractors, so no state statute requires a license to act as your own general contractor on your own house. For electrical work, the state licensing law does not apply to work performed in or on a dwelling by a person who owns and resides in it, but only where no municipal ordinance specifically regulates that work, so city electrical licensing and permit rules still control inside city limits (Occupations Code 1305.003(a)(6)). For plumbing, a property owner does not need a state license to perform plumbing in the owner's homestead (Occupations Code 1301.051). In opt-in counties' unincorporated areas, an individual who builds their own house or acts as their own contractor is exempt from the Class C misdemeanor penalty for inspection notice failures if they intend to use the home as their primary residence (Local Government Code 233.157(c)). None of these exemptions waive local permit or inspection requirements where they apply. Confirm how Harris County applies this before you apply.
