Why standby generator installation comes up in Houston
After Hurricane Beryl in 2024 left more than two million CenterPoint customers without power in summer heat, many Houston families added standby generators sized to run central air. A natural-gas unit with an automatic transfer switch is the most common choice, and the gas meter may need upgrading to supply it. Units must sit outdoors with clearance from windows, doors and property lines, and in flood-prone areas they should be raised on a platform.
Some HOAs set screening rules. Permits come from the City of Houston's permitting center, and gas work needs its own permit.
- After hurricanes and the 2021 winter storm, standby generators and portable-generator inlets with interlocks became some of the most requested projects in the area.
- After repeated hurricanes and the February 2021 winter storm, standby generators and generator inlets with interlocks are among the most requested electrical projects in the Houston area.
- A whole-home standby unit needs a transfer switch, a correctly sized natural-gas line and placement that meets clearance rules; in flood-prone areas, mounting height matters too.
- Adding a larger AC system, a pool, an EV charger or a standby generator often requires an upgrade.
- Permits in Houston
- Inside city limits, electrical permits come from the City of Houston's permitting center; unincorporated Harris County and suburban cities have their own rules. Texas electricians are licensed by TDLR.

How the work is done
1. Load and site review
The electrician decides which circuits to back up, sizes the unit, and picks a compliant spot outdoors.
2. Permits and fuel
Electrical and, often, gas or propane permits are pulled, and the fuel supply is checked for capacity.
3. Install unit and transfer switch
The pad, generator, automatic transfer switch and wiring are installed; a gas fitter connects the fuel.
4. Inspection and startup
The work is inspected, the unit is started, and the transfer is tested.

Standby Generator Installation in Houston: questions
Do I need a permit for standby generator installation in Houston?
Usually, yes. Inside city limits, electrical permits come from the City of Houston's permitting center; unincorporated Harris County and suburban cities have their own rules. Texas electricians are licensed by TDLR. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Houston?
If the work affects the meter or service, the electrician coordinates with CenterPoint Energy (lines and meters); retail provider of your choice, which owns the meter and service drop.
What size standby generator do I need?
It depends on what you want to run. Essential circuits may need a smaller unit; whole-house backup with central air needs more. A load calculation decides.
Standby or portable generator?
A portable generator with an inlet and interlock costs less but has to be set up and refueled by hand. A standby unit starts and switches over by itself.
Can a standby generator run on propane?
Yes. Most run on natural gas or propane; the fuel supply must be sized for the unit.
How close to the house can it go?
Manufacturers and local codes set clearances from windows, doors, vents and property lines; the installer follows both.
