Every other city page on this site defines itself against this one. Pasadena is not Houston. Bellaire is not Houston. Cypress is not Houston. So it is worth setting out what an address actually inside the city limits means for a charger installation, because the boundary is not where most people think it is and the rules inside it are unusual.
The city limits are not intuitive
Houston’s boundary is not a circle. Annexation and the strip-annexation of highway corridors left the city reaching well past anything you would draw from the map.
Kingwood sits far north of the city proper, past Humble, and permits through the City of Houston. Atascocita, immediately across the river, goes to Harris County. Clear Lake is City of Houston too, a good twenty miles south of downtown with Seabrook and Webster as independent neighbours.
Meanwhile Bellaire, West University Place and Southside Place sit entirely surrounded by Houston and run their own building departments.
If you are unsure, the address decides it, not the postal city on your mail. We check before quoting, because it changes the permit office, the fee and the inspection schedule.
Permits go through iPermits
City addresses permit through the Houston Permitting Center. Electrical work of this class — new circuits, panel changes, service upgrades — requires a permit pulled by a licensed electrical contractor and an inspection afterwards.
This is not optional and it is not a formality. It is also not a reason to inflate a quote: the permit is a modest line item, and any installer treating it as a major cost driver is telling you something about how they price.
No zoning means your deed restrictions decide
Houston is the largest city in the United States without a zoning ordinance. What governs your property instead is the private deed restriction attached to your subdivision.
For a charger this matters in one specific way: where you may mount equipment on a street-facing elevation. A zoning code would give you a setback rule you could look up. A deed restriction gives you a document, sometimes decades old, that may or may not say anything about exterior equipment — and in Houston the city can enforce those private restrictions rather than leaving it to neighbours, which is unusual and makes the document worth reading rather than assuming.
The document is recorded and you can pull it. For most of the city it sits in the Harris County Clerk’s real property records, and your civic club or HOA will normally have a copy to hand. What you are looking for is any clause covering exterior equipment, mechanical equipment, or alterations visible from the street.
In practice most installations go in a garage or on a side or rear elevation, and the question never arises. Raise it early only if you want the unit somewhere visible from the street.
Recorded restrictions vary subdivision by subdivision and are amended over time. Our team confirms what applies at your address before committing to a mounting position.
Inner-loop services are the real constraint
The Heights, Montrose, the Third Ward, Garden Oaks and Acres Homes carry housing built between the 1920s and the 1940s. Renovation has been uneven. Some of those homes have had a full service replacement; some are still on 60-amp or 100-amp equipment behind a modernised kitchen.
Adding a 40-amp continuous load to that is a question with three possible answers — it fits, it fits with load management, or the service has to grow — and only a whole-home load calculation separates them. We would rather do the calculation than sell you the largest of the three answers by default.
Post-2000 infill on the same streets is generally on 200-amp service and usually has room.
Historic districts
Houston has protected historic districts — several in the Heights, others including Old Sixth Ward, Avondale, Westmoreland and Glenbrook Valley — where exterior alterations visible from the street go before the Houston Archaeological and Historical Commission for a Certificate of Appropriateness.
Where a charger lands depends entirely on where it goes. Inside the garage is not an exterior alteration and does not trigger review. On a rear or alley elevation — which, given how Heights lots are laid out, is where most of these go anyway — it generally does not either. On a street-facing wall it may.
The certificate is a scheduling matter, not an obstacle: applications are heard on a published calendar. It only becomes a problem when nobody raises it until the crew is on site.
District boundaries and review criteria are set by the commission and do change. Our team confirms whether your address and intended mounting position need a certificate before scheduling the work.
Flood-prone addresses
After Harvey the city tightened its floodplain rules considerably, raising elevation requirements for construction in the mapped floodplains.
It is worth being precise about what that does and does not reach. Those rules govern new construction and substantial improvements to a structure. Adding a charger is neither, so the ordinance does not by itself impose an elevation requirement on your installation.
What it should change is where the equipment goes. On a property that took water in 2017, mounting a charger and its disconnect at standard height is a decision you get to regret exactly once. We site equipment above the recorded flood level on those addresses as a matter of course. Decided at the survey it usually costs nothing; decided on installation day it costs a return visit.
If your street flooded in 2017, tell us at the first call.
Floodplain maps and the city’s elevation requirements are both revised periodically. Our team confirms what currently applies at your address before the work is scheduled.
What we install here
Level 2 charging and Tesla Wall Connectors lead, with panel upgrades and load management close behind inside the Loop.
Your electricity is delivered by CenterPoint Energy regardless of which retail provider you buy from — the meter and the service drop are theirs, and a service upgrade is scheduled through them.
Call (346) 406-1223 and we will confirm your permit authority before anything else.
