What’s involved
- Sizing: a load calculation decides whether you power the whole house or key circuits like AC, refrigerator and lights.
- Gas: a licensed plumber sizes and runs the gas line; your meter may need an upgrade from the gas company.
- Electrical: a licensed electrician installs the automatic transfer switch.
- Pad and placement: a level pad with manufacturer clearances from windows, doors and property lines.
- Permits: electrical and plumbing (gas) permits with inspections.
What your HOA can and can’t do
Under Texas Property Code § 202.019, an HOA generally can’t prohibit a permanently installed standby generator. It can require licensed installation, reasonable screening if visible from the street or neighbors, set testing times, and regulate location, but location rules can’t raise installation costs by more than 10%.
Common questions
How much does a whole-house generator cost in Houston?
Remodeling’s 2025 report estimates about $13,289 in Houston for a typical backup generator project. Larger units, longer gas runs and meter upgrades cost more.
Can my HOA stop me from installing a generator?
Generally not. Texas Property Code § 202.019 protects permanently installed standby generators, with limits on placement and screening.
