How Long Does a Standby Generator Installation Take, and What Permits Does It Need?

Homeowners often ask for a number of days, and we understand why. You want to know when the power will be backed up. The honest answer is that a standby generator installation is a chain of steps, and the total time depends on how smoothly each link goes. A simple install on a lot with an easy gas connection and a quick permit moves differently than one that needs a longer gas run, a service panel change or extra review.

Part of the timeline is work our crew does on your property. Part of it is waiting on other people, such as the permit office, the inspector, the gas provider or the utility. Those waits are the hardest to predict, so we will not promise a date we do not control. What we can do is walk you through each stage so you know what is happening and why.

Every home is different, but most installs follow this general path.

1. Site visit. We look at where the generator could sit, where the gas line and electrical panel are, and what the neighbors and property lines allow. This is also when we ask what you want to keep running.

2. Sizing. We work out the electrical load the generator needs to carry, including air conditioning and other motors that draw extra power when they start. Sizing is a calculation, not a guess, and it comes before a final proposal.

3. Permit. The permit application goes to the city or county that covers your address. Requirements differ from place to place, so we go by what the permit office for your address asks for.

4. Pad. The generator sits on a level base. Depending on the site and local rules, that may be a poured pad or a prefabricated one. Concrete may need time to cure before the unit is set.

5. Gas line. A licensed professional runs the fuel connection from your meter or tank to the generator. Where applicable, the gas provider may need to be involved, particularly if the meter needs attention.

6. Electrical. Conductors are run between the generator, the transfer switch and your panel, and the work is done to local code.

7. Transfer switch. This device moves your home from utility power to generator power and back, and it keeps generator power from flowing out onto utility lines. It is set up as part of the electrical stage.

8. Inspection. The inspector for your area reviews the work. If something needs correcting, it is fixed and rechecked.

9. Utility coordination. Where applicable, the utility may need to review the installation. We handle that paperwork, but we cannot speed up a review that is out of our hands.

10. Startup. Once the work passes, the generator is started, tested under load, set up with its exercise schedule, and we show you how it works.

A standby generator touches gas, electricity and sometimes the footprint of your property, so it is normally treated as permitted work. The specifics, including what is submitted, what is inspected and how long it takes, are set by the city or county that covers your address. If you live in an area with a homeowners association, there may be an additional approval for where the unit can go.

We do not ask homeowners to pull permits themselves. As your licensed electrical contractor, we prepare the application and schedule inspections. Be wary of anyone who offers to skip the permit. An unpermitted generator can cause trouble with insurance, with a home sale and, most importantly, with safety.

A word on timing: the permit office and inspectors work on their own schedules, which can be busier after storms and during hurricane season. Ask us where your application stands at any time.

Several things can add time, and most of them are worth knowing about before you sign anything.

Permit and inspection backlogs are the first. The second is the gas side, since a longer run or a meter that needs review takes extra steps. A third is the electrical service. If your panel is full or aging, it may need work before the transfer switch can go in. Equipment availability can also play a role, particularly if demand surges ahead of a storm. Finally, weather matters. Rain can delay concrete, trenching and outdoor work in this part of Texas.

If you are thinking about a generator, starting early helps. A calm month gives everyone more room than the week a storm is forecast.

Decide early which circuits or how much of the house you want covered, because that drives sizing. Tell us about any HOA rules and send over approval letters. Make sure we can reach the gas and electric meters and the area where the unit will sit. Keep your contact information current so inspection appointments are not missed.
