A generator install touches your gas service, your electrical service and usually your HOA. Knowing the steps makes it much easier to compare quotes and spot what’s missing.
The process, step by step
- Site visitThe installer checks your panel, gas meter, legal placement spots, drainage and flood exposure.
- Load calculationAC tonnage, heat type, appliances and pumps decide the generator size and transfer switch.
- QuoteYou pick the brand, size and coverage, and get an itemized written price.
- Gas checkThey confirm your meter and piping can feed the generator plus your other gas appliances. If not, they request a meter upgrade.
- Permits and HOAPermits from the City of Houston or your local city. HOA approval first in many communities.
- Pad and setThe unit goes on a pad with proper clearances. Raised if the lot floods.
- Gas and electricalA licensed plumber runs gas. A licensed electrician installs the transfer switch and load modules.
- Inspection and startupAfter inspection, they fire it up, simulate an outage and show you the controls and app.
What pushes the price up
- Long runs from the gas meter or panel to the generator spot
- A gas meter upgrade
- Service-rated transfer switch and extra load modules
- An old or full panel that needs replacing
- Raised pad, trenching or concrete cutting
- City permit and inspection fees

Questions to ask every installer
| Ask this | Why it matters |
|---|---|
| Who does the gas and electrical work? | Both trades need proper licensing. Know if it’s subcontracted. |
| Can I see the load calculation? | It’s the basis for the size you’re paying for. |
| What’s not included? | Pad, permits, meter upgrade and startup are common gaps. |
| Are you factory-authorized for this brand? | It can affect warranty registration and service. |
| How busy do you get after storms? | You want service when it counts. |
Winter and early spring are the quiet months for Houston installers. Start then and you’ll usually get faster site visits, permits and equipment.

Common questions
How long does it take from start to finish?
The install itself is often one to three days. Start to power-on is usually several weeks because of permits, HOA review, equipment and any gas meter upgrade. It can stretch after a big storm.
Do I need a permit in Houston?
Yes. Standby generators generally need electrical and gas permits plus inspections. Your installer should pull them.
Can I install one myself?
Not safely or legally in most cases. It involves gas piping and service-entrance electrical work, and has to pass inspection.
