Generator Placement & Setbacks in Fort Myers Homes
We’ve been getting a lot of calls lately from Fort Myers homeowners asking, “Where can I put my standby generator? Does it have to be a certain distance from the house?”
Good question — and it’s one we’re glad people are asking. Placement isn’t just about where it fits best or looks the cleanest. It’s about safety, code compliance, and making sure your generator runs reliably when you need it most.
We’ve installed hundreds of standby systems around Lee County — everything from 10kW units tucked behind small ranch homes to 26kW setups powering full estates. Every property’s a little different, but the rules stay the same: a generator needs to be placed where it’s safe, accessible, and compliant with local codes.
Here’s how we handle generator placement the right way — the same way we’d explain it standing in your yard, tape measure in hand, planning the install.
Start with Safety: Why Placement Matters
A generator is basically an engine. It burns fuel, creates exhaust, and generates heat — just like a car. So you can’t stick it anywhere that fumes might collect or heat might cause damage.
We’ve seen homeowners (and even some unlicensed installers) try to tuck generators under windows, inside screened lanais, or next to pool heaters — all bad ideas.
Carbon monoxide is colorless, odorless, and deadly. That’s why placement rules are strict, especially here in Fort Myers where outdoor living spaces are close to the house.
A safe placement keeps exhaust gases clear, noise levels manageable, and maintenance access easy.
Setback Rules for Fort Myers Homes
Lee County and the City of Fort Myers both follow the National Fire Protection Association (NFPA 37) and Florida Building Code (FBC) standards for residential generator installations.
Here’s what that means in plain English:
✅ 5 feet minimum from openings.
Your generator must be at least 5 feet away from any door, window, vent, or soffit intake. That’s measured horizontally, from the closest edge of the generator to the nearest opening.
✅ 3 feet from combustible walls.
If the wall is made of wood or has vinyl siding, you’ll need at least 3 feet of clearance. If it’s noncombustible (stucco, brick, or block), you can usually place the generator closer — sometimes as close as 18 inches, depending on the manufacturer’s guidelines.
✅ 18 inches from the house (minimum).
Most generator manufacturers (like Generac and Kohler) require at least 18 inches between the generator and the structure for ventilation and service access.
✅ 5 feet from propane tanks or gas regulators.
For propane-fed systems, you need separation between the generator’s exhaust and any LP equipment. That’s to prevent ignition risks.
✅ Away from property lines and fences.
Most Fort Myers neighborhoods require at least 5 feet from the property line and 3 feet from any fence to comply with fire codes and allow maintenance access.
Those numbers might vary slightly depending on your exact lot zoning, so we always double-check with the Lee County permitting office before finalizing a layout.
Noise Considerations
Modern generators are quieter than ever — most hover around 65–70 decibels at 20 feet, which is about the volume of a normal conversation.
But placement still matters for noise comfort, especially in tight neighborhoods.
We always try to position generators:
Away from bedrooms or patios.
Behind landscaping or utility walls when possible.
On the opposite side of the house from your neighbor’s outdoor living area.
In Fort Myers, HOAs often have additional noise or visibility rules. We’ve worked with dozens of associations and know how to design placements that pass both inspection and neighbor approval.
Pad and Mounting Requirements
You can’t just set a generator on bare ground — not in Florida, where rain and soft soil are part of life.
We install all units on elevated concrete or composite pads, usually 4 to 6 inches thick and slightly wider than the generator base.
That pad does three things:
Keeps the generator level and stable.
Elevates it above minor flooding or standing water.
Reduces vibration and noise transfer to the structure.
In coastal areas like Iona or Sanibel, where flooding risk is higher, we sometimes build custom elevated platforms — either masonry or structural aluminum — to keep the generator above FEMA flood elevation.
Accessibility for Service and Fuel
A generator’s not a “set it and forget it” system. It needs periodic maintenance — oil changes, filter replacements, and inspection. That means we need to leave enough space around it to work safely.
We follow these best practices:
3 feet clear on all service sides.
No overhangs or screens that block ventilation.
Pathway access from the driveway or yard (so techs aren’t wading through flowerbeds).
If your generator runs on propane, we also make sure the tank and regulator are easily reachable for refill trucks. Nothing’s worse than realizing your tank’s trapped behind a privacy fence when the roads are flooded.
Real Job Example: Fort Myers River District
We recently installed a 22kW Generac for a homeowner in the River District. It was a beautiful mid-century home with tight property lines and a lot of glass doors facing the backyard.
They wanted the generator hidden from view, but the only open area was along a stucco wall next to the air conditioning unit.
We mapped out the distances: 5 feet from windows, 3 feet from the AC, and 18 inches from the wall — just within manufacturer specs. We built a 6-inch concrete pad, installed a decorative fence panel for visual cover, and ran conduit underground to the main panel on the opposite side of the house.
The install passed inspection easily, looked clean, and didn’t block any windows or vents.
When Hurricane Milton rolled through a few weeks later, that generator kicked on within seconds and kept the entire house powered for nearly two days.
Permitting and Inspection
Every generator install in Fort Myers requires a permit. We handle the process from start to finish — electrical, gas, and site permits — and meet with the inspector once the job’s complete.
During inspection, the main things they check are:
Correct setbacks from openings and property lines.
Proper pad installation and anchoring.
Safe conduit routing.
Grounding and bonding compliance.
Gas line pressure and leak testing.
We coordinate everything so homeowners never have to deal with the paperwork or scheduling headaches.
Common Placement Mistakes We See
We’ve been called out to fix more than a few installations gone wrong. The most common issues?
Too close to the house — exhaust blowing under soffits or into attic vents.
Too close to windows or sliders.
No pad elevation — water pooling under the unit after rain.
Crowded service area — no room to work or open panels.
Unpermitted installs — which can delay resale or insurance claims.
These might not seem major until your first big storm — then you’ll wish everything had been done by the book.
How We Handle It
When you call us, we don’t just drop a generator where it fits. We:
Walk the property and measure every clearance.
Check local zoning and HOA rules.
Design a pad location that’s safe, quiet, and clean-looking.
Handle permitting, gas coordination, and inspections.
Test everything under load before we leave.
You’ll know your system’s built right — ready for the next storm, without risk of code issues or noise complaints.
Wrapping It Up
Generator placement isn’t guesswork. It’s planning, math, and experience — the kind you only get from doing it over and over in Florida’s climate.
When it’s done right, your generator runs quietly, safely, and automatically every time the grid goes down. When it’s done wrong, it can become a hazard.
👉 Call Coharbor Electric today to schedule your generator consultation. We’ll inspect your property, check all setback requirements, and design a code-compliant installation that looks clean, runs safe, and passes inspection the first time.
We make standby power simple, safe, and built to handle Fort Myers weather — because peace of mind starts before the next storm hits.
