Will a Generator Increase My Home Value?

Last updated: March 2026

Yes. A permanently installed standby generator adds 3 to 5% to your home's resale value. On a $400,000 home, that's $12,000 to $20,000 potentially recovering most or all of the installation cost at sale.

Something shifted in 2025: backup power generators cracked the top 10 remodeling projects in the national Cost vs. Value Report for the first time ever. Generators have been around for decades, but the market is finally catching up to what homeowners in Florida, Texas, and Michigan already knew: reliable power is a selling point, and buyers will pay for it.


The ROI

The national average return on investment for a standby generator installation is 54%: a $12,860 installation adds roughly $6,940 to resale value. That's based on the 2025 Cost vs. Value Report published by Zonda/Remodeling Magazine.

In storm-prone regions, the ROI jumps significantly. Florida, the Texas Gulf Coast, and the Carolinas see 100%+ ROI. the generator adds as much or more to the home's value as it cost to install.

The range across markets: 50 to 75% is typical nationally. Over 100% in areas with frequent or severe outages.


How That Compares to Other Home Improvements

A generator isn't the highest-ROI project you can do. But it holds up well against common renovations, especially in the right market.

ProjectAverage CostNational ROI
Garage door replacement~$4,500268%
Steel entry door~$2,400188%
Manufactured stone veneer~$11,300153%
Minor kitchen remodel~$28,000113%
Standby generator~$12,86054% national / 100%+ storm zones
Bathroom remodel~$25,25074–80%
Wood deck addition~$18,20078–95%
Major kitchen remodel~$155,00034%

At 54% nationally, a generator sits solidly in the middle of the pack: better than a major kitchen remodel, comparable to a bathroom renovation. In storm markets, it outperforms nearly everything on the list except the cheapest projects.

The difference: a garage door replacement doesn't prevent $25,000 in frozen pipe damage. A generator does. The ROI number only captures the resale value increase; it doesn't capture the avoided costs of outages, which can dwarf the installation price.


Where Generators Add the Most Value

The resale impact isn't uniform. It depends on where the house is.

Strongest markets:

  • Hurricane zones: Florida, Texas Gulf Coast, Carolinas, Louisiana
  • Ice storm regions: Michigan, Oklahoma, Maine, the upper Midwest
  • States with the most major outages (2000–2023): Texas (264 events), California (238), Michigan (174)
  • Rural areas with frequent or prolonged outages and limited grid redundancy

In these markets, buyers actively look for homes with generators. Properties with backup power sell faster, and agents use it as a differentiator in listings.

Weaker markets: Areas with stable grids and mild weather — parts of the Pacific Northwest, the desert Southwest — see less resale impact. The generator still adds value, but it's not the selling point it is in hurricane country.


How Appraisers Treat Generators

It's not straightforward, though.

A permanently installed standby generator is classified as real property: part of the dwelling structure, like your HVAC system or water heater. It falls under Coverage A (Building/Dwelling) in insurance terms. Appraisers can include it in their valuation.

A portable generator is personal property: like a lawn mower or a space heater. It falls under Coverage C (Contents/Personal Property). It adds nothing to the appraised value of the home.

The caveat: appraisers have mixed views on how much value to assign. In hurricane zones, generators are still rare enough — appearing in roughly 1 in 300 homes — that there isn't always enough comparable sales data for a standard adjustment. Some appraisers include a specific dollar figure. Others note it as a positive feature without assigning a hard number.

Depreciation also matters. A brand-new generator adds more value than a 10-year-old unit. If you're selling, having recent maintenance records and a transferable warranty makes the generator a stronger selling point.


The Insurance Discount

Beyond resale, a standby generator earns an ongoing discount on your homeowners insurance premium.

Typical discount: 2 to 10%, with most homeowners seeing about 5%. On a $1,500 annual premium, that's $75 to $150 per year.

Requirements:

  • Must be permanently installed (not portable)
  • Must have documented annual professional maintenance
  • Some insurers want proof of a maintenance agreement

Over 20 years: $1,500 to $3,000 in cumulative premium savings.

Portable generators get no insurance discount. The insurer doesn't care about a generator in your garage: they care about a permanently wired system that prevents claims automatically.

The bigger insurance story is the claims you never file. A standby generator prevents the burst pipes, the flooded basements, and the spoiled food that generate five-figure insurance claims. Avoided claims keep your premiums from spiking for years. The 5% annual discount is nice, but the real savings come from never triggering the rate increases that follow major claims.


Buyer Demand Is There

The market conditions are in your favor:

  • Only 15% of Americans currently have backup power. But 61% wish they did. That's a massive gap between desire and adoption.
  • 84% of Americans are concerned about growing power outages. Grid anxiety is real and rising.
  • The grid is aging: most of the nation's transmission infrastructure is past its designed lifespan. Reliability is going the wrong direction.
  • 2024 was the worst outage year in a decade: 11 hours average per customer, nearly double the prior decade.

The buyers who care most: families with children, seniors, remote workers, and anyone who's lived through a multi-day outage. In storm markets, "whole-home generator" in a listing is becoming as expected as "new roof" or "updated kitchen."


The Full Financial Picture Over 20 Years

Stack every financial benefit against the total cost of ownership and you get a clear picture:

Financial BenefitValue
Resale value increase (3–5% on $400K)$12,000–$20,000
Insurance premium savings (20 years)$1,500–$3,000
Avoided damage (one major event)$4,000–$30,000
Total potential benefit$17,500–$53,000
CostValue
Installation (22 kW)$12,000–$17,000
Maintenance (20 years)$4,000–$9,000
Fuel (20 years)$2,750
Batteries (20 years)$800
Total 20-year cost$19,550–$29,550

In storm-prone areas where a major event is likely over 20 years, the financial case is clear; the benefits match or exceed the costs. In mild-weather areas, it's closer to break-even on pure dollars. But that calculation doesn't include the value of never sitting in a dark house wondering when the power comes back.

Frequently Asked Questions

How much does a generator increase home value?
Three to five percent, or $12,000 to $20,000 on a $400,000 home. The increase is higher in storm-prone regions (Florida, Texas, Michigan) where buyers actively seek homes with backup power. Portable generators add nothing to resale value: only permanently installed standby units count.
What is the ROI on a standby generator?
54% nationally: a $12,860 installation adds about $6,940 in resale value. In hurricane and storm zones, ROI exceeds 100%. Among common home improvements, generators rank in the middle of the pack nationally but near the top in outage-prone markets.
Do home appraisers count generators?
Permanently installed standby generators are classified as real property (part of the dwelling) and can be included in appraisals. Portable generators are personal property and are not counted. Appraiser treatment varies: some assign a specific dollar figure, others note it as a positive feature without a hard number. Having maintenance records and a transferable warranty strengthens the valuation.
Does a generator lower homeowners insurance?
Yes: 2 to 10% discount on premiums, typically about 5%. Must be permanently installed with documented annual maintenance. On a $1,500 annual premium, that's $75 to $150 per year in savings. Over 20 years: $1,500 to $3,000. Plus the prevented claims (frozen pipes, flooding, food spoilage) that would spike your premiums for years.
Is a generator a good investment for my home?
In storm and freeze zones, yes; the financial math favors the generator over 20 years when you factor in resale value, insurance savings, and avoided damage from even one major outage. In mild-weather areas, the financial ROI is moderate, but you're also buying something that doesn't show up on a spreadsheet: the certainty that your family's comfortable no matter what happens to the grid.
