How Much Does It Cost to Install a Standby Generator in Melbourne, Florida?

An installed standby generator typically costs about $6,500–$9,000 for an essential-circuit system of around 14 kW and $9,000–$16,000 for a whole-home system of about 20 to 26 kW, based on our Florida planning ranges. Those estimates include the generator, automatic transfer switch, pad and installation. A gas line usually adds $400–$1,500, and permit fees and any propane tank are extra.

We found no published installed prices for Melbourne or Brevard County. This page applies the Florida ranges to Space Coast homes and covers the four things to settle before you compare quotes: size, fuel, placement and which office issues your permit.

Standby generator cost estimates for Melbourne and Brevard

Installed home standby generator cost (generator, automatic transfer switch, pad and installation)

Item	Estimated range	What affects it
Standby generator for essential circuits (about 14 kW)	$6,500–$9,000per system	Powers selected circuits such as the refrigerator, lights, some outlets and fans. Florida installer figures (2025).
Whole-home standby generator (about 20 to 26 kW)	$9,000–$16,000per system	Sized to run most of the home, often including central air. Larger units, long gas runs and load management cost more.

These are statewide planning ranges, based mainly on one Florida installer's 2025 published figures (shown below with other published estimates). They don't include permit fees, the gas line (priced below) or a propane tank. Larger units, long gas runs and load management cost more, and Space Coast quotes can land outside these ranges.

Essential circuits or the whole home

• Essential circuits (about 14 kW). The generator powers circuits you choose in advance, such as the refrigerator, some lights and outlets, and fans.
• Whole home (about 20 to 26 kW). The generator is sized to run most of the house, often including central air. If keeping the air conditioning on matters to you, price this size range.

At matching ends of our ranges, stepping up to a whole-home system adds about $2,500 at the low end ($9,000 − $6,500) and about $7,000 at the high end ($16,000 − $9,000). Ask each installer to show how they sized the unit: which appliances and air conditioners it should carry, and whether it uses load management to keep large loads from starting at once.

Basic, standard and premium installations

• Basic (low end). An essential-circuit generator on a standard pad close to the gas meter, with a short gas run and no changes to the electrical service.
• Standard (middle). A whole-home unit sized for central air, a whole-house automatic transfer switch and a moderate gas run.
• Premium (high end). A larger whole-home unit with load management, a long gas run or a new propane tank, a gas meter upgrade, electrical service work, or a spot that takes extra work to meet clearance rules.

What published Florida figures show

We found no installed generator prices published by a Melbourne or Brevard installer or cost guide. The closest figures:

• One Florida Panhandle installer's 2025 figures put a 14 kW system at about $6,500–$9,000 installed, 22 kW at $9,000–$13,000 and 26 kW at $11,000–$16,000.
• A 2026 consumer guide for Miami puts a whole-home standby generator at about $6,000–$15,000 installed.
• A national generator information website (undated) gives about $7,000–$15,000 for an installed whole-house generator.

These are published marketing and cost-guide estimates, not records of completed Brevard jobs, and they don't spell out exactly what's included. They broadly agree with our ranges, so use them as a sense check and judge each quote by its written scope. Our page on how we estimate costs explains where our ranges come from.

Where the money goes

A standby generator quote usually bundles several pieces of work:

• The generator. One undated Tampa cost-calculator page lists a 22 kW dual-fuel unit at about $6,000 for the equipment alone, before labor.
• The automatic transfer switch. It moves the house to generator power when the utility fails and keeps the generator from feeding power back into the utility lines. The same Tampa page lists the switch at $500–$1,200 for the equipment.
• The pad. The Tampa page lists one at about $390.
• Electrical work. Wiring from the generator to the transfer switch and panel, done by a licensed contractor under a permit.
• Gas piping. A line from the gas meter or propane tank to the generator. Length is the main variable.
• Permits and paperwork. Permit fees, plus a recorded Notice of Commencement, which the building department needs before the first inspection when the direct contract is over $5,000. Every budget on this page is above that.

Other generator costs

Item	Estimated range	What affects it
Gas line to the generator	$400–$1,500per job	Piping from the gas meter or propane tank. Longer runs, a new propane tank or a meter upgrade add cost.

A 2026 national cost guide gives about $400–$1,500 or more for a generator gas line, in line with our range. A long run around the house, a new propane tank or a meter upgrade pushes the cost up.

Natural gas or propane in Brevard

Standby generators commonly run on natural gas from the utility or on propane from a tank on your property. Dual-fuel units, like the one on the Tampa page, can use either.

Natural gas. A 2023 tariff filing with the Florida Public Service Commission lists Melbourne, Palm Bay, Cocoa, Rockledge, Titusville and Cape Canaveral among the Brevard communities in one gas utility's service territory, and a 2024 commission agenda item says that utility serves residential customers in Brevard. Being in a listed city doesn't mean there's a gas main on your street, and we didn't check whether other gas utilities serve parts of Brevard. Check your address with the gas utility before you get quotes, and ask whether your home would need a new meter or a meter upgrade.

Propane. Without gas service, the generator runs from a propane tank that you buy or lease from a propane supplier. We found no reliable price for a tank on a generator job, so ask for it as a separate line in each quote, along with an estimate of how long a full tank will run the generator at the load you expect.

Brevard County's generator permit page doesn't mention gas piping or tanks. Elsewhere in Florida, Lake Wales requires propane tanks to meet the NFPA 58 distance tables and wants a separate application for tank or gas piping work from a licensed plumbing or gas contractor, or an LP gas installer licensed by the Florida Department of Agriculture and Consumer Services. Broward County's generator checklist sets a 10-foot minimum from the fuel tank to the structure and to the property line. Those are other jurisdictions' rules, not Brevard's, so ask your building department whether gas or tank work needs its own permit and which tank setbacks apply.

We found no published source that compares installed costs for natural gas and propane systems.

Where the generator can go

Placement drives the length of the gas run and the permit review. In unincorporated Brevard, the location goes on the to-scale survey filed with the permit application.

• 5 feet from openings. One generator manufacturer's support article, citing NFPA 37 (a National Fire Protection Association standard for stationary engines), says outdoor generators must be at least 5 feet from wall openings, such as operable windows, doors, vents and window wells, and at least 5 feet from structures with combustible walls.
• 18 inches from a wall for some models. The same manufacturer's manuals list an 18-inch minimum rear clearance for some models. Its support page says that applies only to units marked with the Southwest Research Institute (SwRI) testing logo, and that local codes take precedence.
• Openings still count. New Hampshire's fire marshal's office, explaining NFPA 37, says the reduced spacing for tested units applies only to the distance from a combustible wall, never to the distance from a building opening. That is out-of-state guidance, not Florida law, but it shows how an inspector may read the rule.

We found no Florida Building Code text on generator clearances, and we couldn't confirm which edition of NFPA 37 Brevard County, Melbourne or Palm Bay enforces. Before you settle on a spot, ask your building department which clearances it requires and whether it accepts the 18-inch spacing for tested units.

Space Coast site checks

• Tight lots. Keeping 5 feet from windows, doors and vents, plus any setback your city or HOA applies, can rule out the side yard on a narrow lot. A spot farther from the meter means a longer gas run.
• Flood zones. If your home is in a FEMA special flood hazard area, ask the building department whether the generator or transfer switch has to sit at a minimum height. We didn't find a Brevard rule on this, so don't assume either way. Brevard County's Floodplain Administration page has an interactive flood zone map; inside a city, ask the city which floodplain rules apply.
• Salt air. On the barrier island or along the Indian River, ask the installer what the manufacturer's instructions and warranty say about salt-air exposure, and how the enclosure and its fasteners will hold up.
• HOAs. If you have a homeowners' association, check whether it must approve equipment on the outside of the home. HOA approval is separate from the permit; see HOA approval in Florida.

Permits in Brevard County and the cities

A permanently installed generator needs permits and inspections; our electrical permits guide explains the electrical side and who can do the work. Which office issues the permit depends on whether your home is inside city or town limits.

Unincorporated Brevard (Viera, Suntree, Merritt Island)

Brevard County Planning and Development issues a Residential Generator permit "for the installation of whole-house generator, including all electrical and plumbing." At our October 2026 check, the county's page said:

• Who applies. Building, electrical and general contractors can apply, and each can pull permits only for work within their license.
• Documents. The manufacturer's specifications and installation details, and a property survey drawn to scale showing where the generator will go.
• Review. County staff review the application before the permit is issued.
• Fees. A $25 application processing fee, due when the application is submitted. Permit fees come on top, and we didn't find the county's full fee schedule.
• Other documents. The page is only a guide, and the county may ask for more.

The page doesn't mention gas piping or a propane tank, so ask whether that work needs its own permit. Licensed contractors apply through the county's BASS online system. Our Brevard County permit guide covers the county process.

Melbourne, Palm Bay and other cities

• City of Melbourne. The Building Section takes permit applications through the city's EnerGov portal. We didn't find a Melbourne page specific to generators, so ask the Building Section what to submit. Fees are set by the city's building permit fee schedule, effective August 7, 2026.
• City of Palm Bay. The Building Department takes electronic submissions through its ePermitHub Digital Plan Room, while some city pages still point to its iMS e-Portal, so ask which one to use. Palm Bay also requires state-licensed contractors to register with the city before they pull permits there.
• Other cities and towns. West Melbourne, Satellite Beach, Indian Harbour Beach, Melbourne Beach and Cocoa Beach handle permits through their own offices. For Indialantic and some other towns, ask town hall who reviews permits. Wherever you are, ask whether gas or propane work is permitted separately.

Florida's 2026 $7,500 small-project permit exemption doesn't help here. It doesn't cover electrical, plumbing, mechanical, structural or gas work, and every generator installation includes electrical work.

Sample budgets

These illustrative estimates use only our planning ranges: each adds the system range to the gas line range ($400–$1,500). They aren't quotes, and they leave out permit fees, which vary by building department.

Scenario 1: Essential circuits in Melbourne. Assumptions: a single-story home inside Melbourne city limits, natural gas available at the street, a 14 kW essential-circuit system, a spot near the gas meter that meets clearances, and no electrical service upgrade. Math: $6,500 + $400 = $6,900 at the low end; $9,000 + $1,500 = $10,500 at the high end. Estimate: about $6,900–$10,500, plus Melbourne's permit fees.

Scenario 2: Whole home in Viera. Assumptions: a home in unincorporated Brevard with central air, natural gas service, a whole-home system of about 22 kW and a moderate gas run. Math: $9,000 + $400 = $9,400; $16,000 + $1,500 = $17,500. Estimate: about $9,400–$17,500, plus the county's $25 application processing fee and its permit fees.

Scenario 3: Whole home on propane in Satellite Beach. Assumptions: a barrier island home whose street has no gas main, a whole-home system running on propane, and a tank placed where the building department and propane supplier accept it. Math: the same as scenario 2, $9,000 + $400 = $9,400 and $16,000 + $1,500 = $17,500, with the gas line run from the tank instead of a meter. Estimate: about $9,400–$17,500 before the tank, which you would buy or lease separately, plus the city's permit fees. The tank is the missing number, so get it priced before you compare propane with other options.

Real quotes depend on your home's electrical system, the distance to gas, the generator brand and size, and what each installer includes.

Maintenance and running costs

A standby generator needs periodic servicing so it starts when the power goes out. A 2026 consumer guide for the Miami area puts a service or maintenance plan at about $400–$500 a year. We found no Space Coast figure. Ask what a plan covers, how often the technician visits and whether servicing is required to keep the warranty, and follow the maintenance schedule in the owner's manual.

Fuel is the other running cost. We didn't find reliable figures for how much natural gas or propane a generator uses during an outage, so ask the installer to estimate it for the unit and load you're buying.

Portable generators and carbon monoxide

If a standby system isn't in the budget yet, a portable generator is the usual stopgap. Don't connect one to house wiring without a proper transfer device, because it can feed power back into the utility lines. The U.S. Consumer Product Safety Commission says never to run a portable generator inside a home, garage, basement, crawlspace or shed, even with doors and windows open, and recommends running it at least 20 feet from the house with the exhaust pointed away. It also recommends carbon monoxide alarms on every level of the home and outside sleeping areas.

Common mistakes to avoid

• Choosing a size without a load list. Write down what must run, especially central air, before you compare kW ratings, and give every installer the same list. An undersized unit can't carry the house; an oversized one costs more than you need.
• Leaving the tank out of a propane budget. A propane quote that leaves out the tank isn't comparable with a natural gas quote. Ask for the tank, bought or leased, as its own line.
• Comparing bids with different scopes. The 2026 Miami consumer guide suggests checking that each bid includes the equipment, labor, permits, inspections and the concrete pad before you compare prices. Our guide to why contractor quotes differ shows how to line them up.
• Waiting for a storm. The same guide says installers in Florida's hurricane areas book up months ahead of hurricane season, which runs June through November. Planning in the off-season gives you more time.
• Skipping the permit to get power back faster. After a hurricane, be wary of anyone who offers that. See storm repair scams in Florida.

Next steps

1. Find your permit office. Confirm whether your home is in unincorporated Brevard or inside a city, using our Brevard County permit guide.
2. Check gas service. Look up your address with the gas utility. If there's no service, plan for propane.
3. Ask about placement early. Have each installer mark the proposed spot on a site sketch, with distances to windows, doors, vents and property lines, and confirm the clearance rules with your building department.
4. Get written quotes with the same scope. Each should list the generator model and size, transfer switch, pad and how the unit is secured to it, gas piping length, tank (if propane), permits, the Notice of Commencement, warranty and any service plan.
5. Check the contractor. Verify licenses on MyFloridaLicense.com and on Brevard County's Licensed Contractor Search, and ask who will do the gas work and what license they hold. Our guide to hiring a contractor in Melbourne walks through the checks.
