Does my North Shore home need a permit for generator installation?

Yes. St. Tammany Parish requires a permit for standby generator installations, and its Department of Permits and Inspections publishes generator and transfer switch guidelines that took effect January 1, 2026. The process includes plan review, permit issuance, and post-installation inspections. After Hurricane Ida, parish permit officials called for tighter generator placement rules because of carbon monoxide incidents, and the inspection protects your family, not just the paperwork. If you live in Hammond or Ponchatoula, you're in Tangipahoa Parish, and if your address sits inside a city limit, the city may issue the permit instead. We confirm which office handles your address, then submit the application and coordinate your inspection.

What size generator do I need for my North Shore home?

Size depends on your electrical load, not square footage alone. Our electricians run a full load calculation covering your HVAC systems, refrigerator, freezer, sump pump, water heater, and any other circuits you choose to keep live. Most homes in St. Tammany Parish are well supported by 20 kW or 26 kW air-cooled systems, and Generac's air-cooled Guardian line tops out at 26 kW. If your home has two or more AC systems, or you're adding an EV charger or hot tub, you may need a 30 kW liquid-cooled unit. A correctly sized generator avoids nuisance shutdowns during peak summer heat, which is exactly when you need it most.

What fuel options are available for home generators in North Shore, LA?

Natural gas and liquid propane are the two primary options, and the right one depends on what already runs to your property. If you live in Folsom , Robert , or Pearl River, you may sit beyond the gas main and rely on an above-ground propane tank, which means you'll monitor the tank level during an extended outage. Natural gas has no tank to refill, but your gas line has to carry the generator's full demand alongside your furnace, water heater, and range, and we check that before we order the unit. The fuel type affects equipment selection, installation scope, and long-term operating performance. We confirm your fuel source during the site visit and plan the installation around it, including the gas permit the parish requires for the line work.

How long does a generator installation take in North Shore, LA?

Most residential standby installations take one to two days on-site once the permit is in hand. Permit review time depends on how busy your parish or city office is, and we give you a realistic project timeline when we write your estimate. If your home needs a panel upgrade or gas line extension, you'll want to factor in extra time for those trades. Starting before hurricane season opens in June means we can finish the permit, the install, and the inspection before the first storm threatens your power.

Will my generator automatically turn on during a power outage?

Yes. Your standby generator starts on its own through the automatic transfer switch, and no one needs to be home or flip a manual switch. The controller waits a few seconds to confirm the outage is real, which keeps a brief flicker from the grid from triggering a start. Once utility power returns, the ATS switches your home back to the grid and shuts the generator off. If you work in Hammond or Ponchatoula and an outage hits during the day, the automation keeps your sump pump and refrigeration protected even when nobody's home.

Can a generator power my whole home in North Shore, LA?

Yes, with proper sizing. A correctly sized standby generator runs your entire electrical load, including central air conditioning. In Louisiana's summer heat, keeping the AC running during a multi-day outage isn't about comfort. It's a health issue. If you live in Madisonville with a single 3-ton or 4-ton AC system, you can typically run everything on a 20 kW unit. If you have two AC systems or other high-draw equipment, we size a larger unit based on a load calculation. We also offer load management options that let a smaller generator handle a larger home by staggering high-draw appliances, which keeps two AC condensers from starting simultaneously and tripping the system.

What affects the cost of a whole house backup generator in North Shore, LA?

Six things we measure at your property decide the total: generator size, fuel type, the distance from the pad to your gas line and electrical panel, the amperage of the transfer switch, any panel upgrades your service needs, and the permit steps your address triggers, such as an Elevation Certificate in a flood zone. After our site visit, you get a written estimate that itemizes the generator, transfer switch, concrete pad, electrical labor, and permit paperwork. You can compare each line before we schedule anything, and we explain any line you want to understand better.

Should I choose a standby generator or a portable generator with an interlock kit?

If you want power the moment the grid drops, choose standby. If you want a smaller commitment, a portable generator works with an interlock kit, which lets you feed selected circuits through your panel without back-feeding the utility lines. You roll the generator outside, run a cord to a power inlet, start the engine, and flip your breakers in the right order, which means someone has to be home to do it. Portable units also need refueling every 8 to 12 hours, and safety agencies say to keep them outdoors and at least 20 feet from your house because of carbon monoxide. If you already own a portable generator, we install the interlock kit or a dedicated outlet for it, and we can add a standby unit later.

Where can a standby generator go on my property in St. Tammany Parish?

Your generator needs at least 5 feet of space from walls, combustible materials, and every opening into your home, including windows, doors, soffit vents, dryer exhaust, and gable vents. A one-hour fire-rated wall, such as brick, can reduce the wall clearance to 18 inches. The parish also wants 3 feet between the generator and your AC units, gas meter, electrical panel, shrubs, fences, and property line, plus 10 feet from outdoor HVAC intake openings. If your house sits on piers, we seal the crawl space for 5 feet on both ends of the generator to keep exhaust gas from collecting underneath. If you're in flood zone A or V, we get the signed and sealed Elevation Certificate that includes the generator's height. We point the exhaust away from your house and aim for 15 feet from your neighbor's home, which the parish recommends, on every standby generator installation in St. Tammany Parish.

Do I need a panel upgrade before generator installation in North Shore, LA?

Sometimes, and we check before we quote. Your transfer switch has to match your service size, and a full 100-amp or 125-amp panel leaves no room for generator circuits. We confirm your main breaker size and meter base before we order the transfer switch, and we look at your panel's bus rating, open breaker spaces, and corrosion on the breakers, which humid Gulf Coast air speeds up in older homes. If you're also planning an EV charger or a hot tub, we may recommend bringing a 125-amp service up to 200 amps first. Then the generator, the new loads, and the transfer switch all work off the same upgraded panel.

Is my generator installation backed by a warranty?

As a Generac dealer, we install equipment covered by Generac's factory warranty on residential standby units. Warranty terms vary by model, and we review those specifics with you at the time of sale. Our work also carries the Neighborly Done Right Promise®. Proper permitting and inspection through the parish also protect your warranty, because most manufacturers require code-compliant installation to honor coverage. Keeping up with the maintenance schedule in Generac's owner's manual counts toward coverage too, and we can walk you through it.

How We Handle Your Home Generator Installation, Start to Finish

Before we recommend a unit, we walk your panel and run a generator load sizing calculation across the circuits you want backed up: HVAC, refrigeration, lighting, sump pump, and any medical equipment. Sizing too small leads to nuisance shutdowns and overloaded circuits. We get it right the first time.
Your standby generator sits outside on a concrete pad and connects to your panel through an automatic transfer switch (ATS). We wire the ATS to monitor your utility feed constantly. When it detects an outage, it signals the generator to start and isolates your home from the grid within seconds. Without that isolation, a running generator can back-feed the utility lines and create a lethal hazard for line workers making repairs.
We set the pad, run the gas and electrical lines, and file your parish permit before we pull the first wire. When we finish, we meet the inspector at your home, since St. Tammany Parish runs the electrical and gas inspections on the same day and needs access inside your house.

Choose Mr. Electric: Why a Generac Dealer Makes Your North Shore Installation Easier

If your home in Mandeville or Covington already sits on Atmos Energy gas lines, your standby generator can run on natural gas that typically keeps flowing during a power outage. That's the key advantage over portable units: no fueling runs in a storm, no carbon monoxide risk from running equipment in a garage, no manual startup when the lights go out at 2 a.m. We handle the gas line connection, the transfer switch wiring, and the concrete pad, and you deal with one crew from the first visit to the final inspection.

When the next storm stalls overhead, you don't want to find out what your generator can't run. Hurricane season runs from June through November, and St. Tammany and Tangipahoa parishes see some of the most frequent and prolonged outages in the state. If the grid stays down for four days, what keeps your refrigerator cold and your sump pump running? Hurricane Ida knocked out power to over one million Louisiana customers in 2021, and communities from Covington to Slidell sat without electricity for days. We're whole-home generator installers and a Generac standby generator dealer, which gives you access to factory warranty support and parts. Our electricians average 10 years of experience, and they know the wiring configurations common to North Shore homes.

If your house still has its original service panel, we check it before we set a generator. We've worked in older homes in Lacombe and Pearl River with original service panels, and we know when electrical panel upgrades need to happen before a generator goes in. When your panel needs more capacity, we handle that work in the same project. Your transfer switch then connects to equipment that can carry the load.

You also get one team handling the permit. We quote by the job, not the hour, so before our electricians touch a wire, you receive a written estimate that itemizes every part of the job, which shows you the whole house backup generator cost line by line. The Neighborly Done Right Promise® backs every installation: if something isn't right, we make it right. Mr. Electric of North Shore, LA serves Madisonville, Hammond, and Ponchatoula along with the rest of the North Shore, and you can contact us today to plan your installation.
