- While luxury homes offer plenty of benefits, they’re often in vulnerable locations and may be highly susceptible to extreme weather.
- Hurricanes, wildfires, floods, and severe storms are just some of the dangerous and often very costly events blighting luxury home areas across the country.
- With widening insurance gaps and increasing extreme weather events likely, the costs will only increase for American homeowners.
While luxury homes are coveted by many, the same characteristics that make them desirable (coastal environment, visible mountain ranges, vast plains) often mean they’re vulnerable to disaster: hurricanes, wildfires, floods, and severe storms.
As extreme weather becomes both more frequent and more costly, this study, from trusted Houston insurance claims lawyers Barcus Arenas, PLLC, looks at where America’s most expensive homes are most susceptible to natural disasters. As well as state vulnerabilities, we’ll look at the specific counties suffering the most from extreme weather, the seasons that feature the most frequent extreme weather episodes, and the types of weather that cause the most damage.
Where Wealth Meets Risk
America’s most expensive homes are disproportionately vulnerable to disaster. Of the 5.99 million owner-occupied U.S. homes worth at least $1 million, 43.3% (2.59 million) are in high-loss counties. That means they are located in the top 20% of U.S. counties with the highest modeled expected annual losses from natural disasters.
To compare, just 16.4% of homes worth under $1 million are in high-loss counties, which means million-dollar homes are 2.6 times more likely to be in the country’s riskiest areas. Luxury features such as ocean views, waterfront lots, and mountain-view settings are often attached to a high risk of hurricanes, wildfires, earthquakes, and flooding.
The overlap between wealth and risk is equally clear within the high-risk counties, with 1 in 6 owner-occupied homes in high-loss counties worth at least $1 million, compared with 1 in 20 elsewhere. Of the 1,454 counties that feature at least 100 million-dollar homes, 237 qualify as high-loss counties; collectively, they hold more than 712,000 homes with a value of at least $2 million.
Nationally, there are 30.8 high-risk million-dollar homes for every 1,000 owner-occupied homes. A state comparison reveals the extent to which luxury homes are situated in disaster-prone areas.
High-risk Hawaii
Hawaii ranks first on the list. Its rate of 352.0 high-risk million-dollar homes per 1,000 owner-occupied homes is over 11 times the national average rate. All of its 109,200 million-dollar homes are situated in high-loss counties vulnerable to flooding, earthquakes, and tsunamis.
California ranks second; its rate of 275.7 per 1,000 is nearly nine times the national average rate. Its 2.09 million high-risk million-dollar homes represent an overwhelming 93.2% of its luxury housing, all of which are susceptible to wildfires, earthquakes, and flooding. California alone accounts for around 8 in 10 of the high-risk million-dollar homes in the U.S.
Florida ranks third (34.2 per 1,000). Its 202,500 high-risk million-dollar homes are all situated in hurricane-exposed enclaves such as Naples, Sarasota, Fort Myers, and the Keys.
South Carolina (23.2), Nevada (22.8), and Colorado (22.3) also feature prominently. South Carolina’s luxury coast (Charleston and Hilton Head) features 62.4% of the state’s million-dollar homes situated in high-loss counties. Nevada’s Lake Tahoe and Las Vegas markets, and Colorado’s wildfire- and hail-exposed Front Range and mountain resort counties, respectively feature 16,419 and 35,060 high-risk million-dollar homes.
Less Vulnerable Major Luxury Markets
While New York features the nation’s second-largest number of million-dollar homes (528,835), just 0.1 per 1,000 are at risk. Similarly, Texas (0.2 per 1,000), Massachusetts (1.5), New Jersey (2.0), and Washington (6.1) also feature substantial luxury markets with comparatively low modeled loss rates. (Eleven states and the District of Columbia feature no million-dollar homes in high-loss counties.)
Ultimately, owning a million-dollar property in Honolulu, Malibu, Naples, or Charleston is risky, with a high number of homes situated in an area where federal models anticipate intermittent disaster damage. When disaster strikes, high property values often mean costly rebuilds and insurance claims, leading to potentially expensive disputes with insurers.
The Counties Facing Greatest Risks
Of the 154 counties that feature at least 5,000 million-dollar homes, 42 rank in the nation’s top 20% for FEMA’s anticipated annual disaster loss rate; 28 rank in the top 10%.
The 25 riskiest markets feature 633,459 million-dollar homes, with 159,096 worth $2 million or more, across counties in California (12 counties), Florida (7), Hawaii (3), South Carolina (2), and Louisiana (1).
In the U.S., as noted, there are 30.8 high-risk million-dollar homes per 1,000 owner-occupied homes. Every top-ten county exceeds this rate, from nearly double the national figure in San Bernardino County to almost 13 times that rate in Maui County.
Major luxury counties can expect average annual losses of $1,493 per $1 million in building value. Every top-ten county exceeds $3,600, with the riskiest facing three to six times the typical rate.
South Carolina and Florida Lead the Coastal Risk
Rankings put Beaufort County, South Carolina (home to Hilton Head Island and Bluffton) as the riskiest major luxury market in the country (99.4th percentile). Its 8,816 million-dollar homes equal 141.0 per 1,000 homes, more than four times the national rate. Its expected annual losses are $5,617 per $1 million in building value, including $4,167 from hurricanes.
Collier County (home to Naples and Marco Island) ranks second (99.3rd percentile), with 26,751 million-dollar homes (11,081 of which are worth $2 million or more). Its rate of 210.5 per 1,000 is almost seven times the national average.
Monroe County (which includes the Florida Keys) ranks third (99.2nd percentile), with 317.5 million-dollar homes per 1,000 (more than ten times the national rate). Around one in three homes in the county is worth at least $1 million, while hurricanes and coastal flooding cause $4,740 in expected annual losses per $1 million.
Martin County (97.4th percentile), which is home to Jupiter Island and Stuart, completes Florida’s presence in the top ten. Its rate is 107.2 per 1,000; hurricanes account for $2,544 of the $3,626 expected in annual losses per $1 million.
California’s Luxury Market Risk: Wildfires, Earthquakes, Flooding
Riverside County (which includes Palm Springs, Palm Desert, and Indian Wells) ranks fourth (98.8th percentile). Its 35,603 million-dollar homes, or 66.4 per 1,000, face $4,860 in expected annual losses per $1 million.
San Bernardino County (96.5th percentile), home to Lake Arrowhead and Big Bear, has 24,913 high-risk million-dollar homes (59.5 per 1,000), and faces an expected $4,729 per $1 million in losses each year.
California wine country location Napa County (97.8th percentile) features 343.9 million-dollar homes per 1,000, over 11 times the national rate; Sonoma County (96.3rd percentile) has 276.2. Both have been subject to severe wildfires and respectively face anticipated annual losses of $4,333 and $4,816 per $1 million.
Hawaii: Subject to the Highest Expected Losses
Hawaii County (which covers the Big Island) ranks fifth (98.8th percentile) and features the list’s highest expected loss rate ($8,954 per $1 million in building value, roughly six times the rate for the typical major luxury county) and a rate of 147.0 million-dollar homes per 1,000.
Maui County (96.1st percentile) completes the top ten, and features the highest luxury concentration of all top-ranking counties: 396.7 million-dollar homes per 1,000, which is nearly 13 times the national average rate. (Nearly two out of every five island homes are worth at least $1 million.)
Other Notable Luxury Enclaves
Just outside the top ten, Marin County (95.7th percentile) features the highest density of luxury homes in the top 25: 753.0 million-dollar properties per 1,000, or roughly three in four homes.
Charleston County, South Carolina (94.4th percentile), faces $4,790 in expected yearly losses per $1 million. Orleans Parish, Louisiana (95.6th), Santa Barbara (93.3rd), Ventura (92.9th), and Honolulu (92nd) also feature prominently.
For homeowners in these markets, these figures highlight the potential financial exposure associated with a covetable location. When losses occur, they can lead to some of the country’s most costly and complex property insurance claims.
Which Disasters Threaten Luxury Homes
America’s million-dollar homes face a wide variety of disaster risks: from earthquakes and wildfires to hurricanes, hail, and flooding.
Earthquakes threaten the most luxury homes
Earthquakes are a serious potential issue for 39.0% of U.S. million-dollar homes (2.34 million), including 628,150 worth at least $2 million, in counties that rank in the top 10% for earthquake risk. These counties feature 228.1 million-dollar homes per 1,000 owner-occupied homes, more than seven times the national rate (30.8).
California is the most vulnerable area: Los Angeles County has 517,240 exposed homes, followed by Orange (280,899), Santa Clara (275,709), and San Diego (218,639). The expected annual earthquake losses are (on average) $1,448 per $1 million in building value ($2,258 in Alameda County).
Wildfires Threaten Luxury Western Markets
Wildfires are a risk for 10.9% of the million-dollar homes (651,180) in top-10% risk counties, at a rate of 127.2 homes per 1,000. San Diego County leads (218,639 homes), followed by Ventura (50,264), Riverside (35,603), and Santa Barbara (31,062).
Western resort markets also face significant levels of risk. Anticipated yearly wildfire losses are $3,168 per $1 million in Washington’s Kittitas County, $2,121 in Utah’s Washington County, and $1,990 in Montana’s Ravalli County.
Hail: an Overlooked Danger
Hail is a serious factor for 4.0% of million-dollar homes (237,082) in top-10% risk counties, especially in Colorado and Texas. Expected yearly losses reach $518 per $1 million in Denver and Arapahoe counties and $502 in Jefferson County. Austin’s Travis County features 45,884 at-risk luxury homes; Dallas County has 31,602. Though less of a headline factor than hurricanes, hail frequently damages roofs badly enough that repairs regularly cost thousands of dollars.
Hurricanes: the Costliest Danger
Although hurricanes threaten just 3.0% of million-dollar homes (178,185), they represent the highest in expected annual losses: $2,523 per $1 million in building value in top-10% risk counties. That’s 1.7 times the earthquake rate, 4.6 times the wildfire rate, and nearly eight times the tornado rate.
North Carolina’s Carteret County faces the highest losses at $5,371 per $1 million, followed by Beaufort County, South Carolina (4,167), Indian River County, Florida (3,861), and Georgetown County, South Carolina (3,852).
Florida’s Collier County features the most exposed luxury homes (26,751), followed by Charleston (18,989), Sarasota (15,698), and Lee County (14,012).
The Flooding Plus Wind Hazards Factor
Coastal flooding threatens 3.8% of million-dollar homes (229,011), concentrated in California’s Marin County (50,159), New Jersey’s Bergen County (32,449), and Massachusetts’ Essex County (24,326). The Florida Keys face the highest expected coastal flood losses, at $899 per $1 million.
Strong winds threaten 1.8% (105,967), mainly along the Jersey Shore. Monmouth County has 26,737 exposed luxury homes, facing $530 per 1 million anticipated yearly losses. Tornadoes threaten an additional 1.5% (90,078), in particular Dallas and Colorado ($334 per 1 million) and Oklahoma County ($238 per 1 million).
FEMA’s inland flood model has flagged 23.0% of million-dollar homes (1.38 million) in top-10% risk counties, chiefly involving Los Angeles, Santa Clara, and Honolulu. Hawaii County faces $4,438 per $1 million in anticipated yearly losses, emphasizing the fact that flood risk extends well beyond coastline areas.
A million-dollar home’s vulnerability to disaster largely depends on its location, with every hazard bringing its own distinct damage and insurance challenges.
Vacation Homes
America’s 4.74 million seasonal, recreational, and occasional-use properties face a disproportionate level of flood risk. Nationally, there are 56.3 vacation homes per 1,000 owner-occupied homes.
Overall, 21.1% of vacation homes are situated in counties that rank in the top 10% for coastal or inland flood damages (compared with 10.5% of primary residences). When it comes to coastal flooding, the gap widens to 9.1% versus 2.5%, meaning vacation homes are 3.7 times more likely to face high risk. If second homes are factored in, it adds 429,527 properties to these coastal counties and increases vulnerability by 20.6%.
In popular beach destinations, vacation homes may outnumber primary residences. Nantucket, Massachusetts, features 1,837 vacation homes per 1,000 owner-occupied homes, followed by Worcester County, Maryland (Ocean City, 1,591), and Cape May County, New Jersey (1,377). Cape May faces $746 in anticipated yearly coastal flood losses per $1 million in building value.
Cape Cod’s Barnstable County features the most flood-exposed vacation homes (55,061), followed by Cape May (49,655), Ocean County, New Jersey (39,863), and Sussex County, Delaware (38,223).
In the Carolinas, hurricane and flood risks overlap, with the Outer Banks in Dare County and the Crystal Coast in Carteret County respectively facing expected hurricane losses of $4,473 and $5,371 per $1 million. The Florida Keys feature the highest coastal flood losses of all vacation markets: $899 per $1 million.
Inland destinations are also vulnerable: Missouri’s Lake of the Ozarks (Camden County) has 1,416 vacation homes per 1,000 owner-occupied homes and ranks in the top 4% in the country for inland flood loss rate.
For second-home owners, distance can mean the risk can become especially problematic, with damage potentially unnoticed for days, and remote claims often triggering disputes over the timeline of events.
Never-Ending Storm Season
For many homeowners, the risk of a storm follows a familiar schedule, with hurricane season stereotypically thought of as largely restricted to between June and November. Yet as federal data clearly shows, damaging storms threaten America’s most expensive homes throughout the year.
NOAA Storm Events records show storms caused $61.7 billion in U.S. property damage between 2021 and 2025, $10.4 billion (16.8%) of which occurred outside hurricane season (between December and May). Even comparatively quiet months average over 200 damaging events (including 516 in December and 513 in February).
The main hazard changes throughout the year, with flooding and high winds causing damage costing $1.03 billion in January, winter storms leading to $427 million in damage costs in February, and tornadoes and hail costing a combined $2.17 billion in March and $4.63 billion in May. Additionally, flash flooding cost $2.59 billion in July, while tropical system damage led to damage costing $15.8 billion in August and $28.1 billion in September.
For luxury homeowners, there is no ‘safe’ month during which they can leave properties unattended or allow their insurance coverage to lapse.
Key Storm States for Luxury Homes
Fourteen states were subject to storm damage during every month in at least three of the five years analyzed. The states feature 64.9% of America’s million-dollar homes (3.88 million), compared with 48.6% of the country’s owner-occupied homes. If we include the states that feature damaging storms in at least 10 months of the year, it raises the share to 84.2% (5.04 million).
California leads with 2.24 million luxury homes (295.9 per 1,000 owner-occupied homes). January is the state’s costliest storm month, due to atmospheric river flooding; 57% of the overall damage occurs between December and May.
New York features 528,835 million-dollar homes (126.0 per 1,000) and is subject to year-round damage, from winter storms and nor’easters to tropical remnants during September.
Texas has 256,990 million-dollar homes, with May the main month for damage. Hail in Dallas, Austin, and the Hill Country causes 54% of damage that occurs outside hurricane season. Tennessee also suffers damage throughout the whole year, with 59% occurring during the offseason, largely due to tornadoes that threaten Nashville’s growing luxury market.
Hurricane States Face Offseason Threats
Florida, which is home to 350,856 million-dollar homes, recorded storm damage during every month of the year (tornadoes led regarding off-season losses). North Carolina and Virginia were also subject to damage during every month.
In Mississippi (85%), Alabama (83%), Missouri (88%), and Arkansas (97%), most storm damage occurs between December and May, largely due to spring tornadoes.
The Projected 2026 Pattern
Preliminary 2026 NOAA data for January to June show Florida, Texas, Tennessee, Virginia, Louisiana, Alabama, Kentucky, Mississippi, Missouri, West Virginia, and Idaho as all suffering from storm property damage during every month of the year so far.
For million-dollar homeowners, preparation, maintenance, and insurance coverage can’t be limited to specific seasons. Storms in February or May can be as devastating as those in September; additionally, claims outside the traditional storm season may face extra scrutiny from insurers.
Million-Dollar Repair Bills
For million-dollar homeowners, the highest costs often come after the storm when a property needs to be rebuilt. According to the Bureau of Labor Statistics, single-family homebuilding material costs have risen 50.6% since February 2020 (including by 9.7% during the past year). A repair that required $100,000 in materials before the pandemic would now cost about $150,600.
For insurance claims, the trend is similar. LexisNexis Risk Solutions’ U.S. Home Trends report found average homeowners insurance claim levels reached a record high in 2025, up 25.9% from 2024 and 93.2% from 2019.
Compounded Disaster Losses
FEMA estimates major luxury counties can expect average annual disaster losses of $1,493 per $1 million in building value, while the counties at most risk face three to six times more. Hawaii County’s expected losses may rise to $8,954 a year per $1 million, or $268,620 across a 30-year mortgage. Beaufort County, South Carolina, faces losses of $168,510 over 30 years, while Sonoma, Riverside, Charleston, and the Florida Keys each face more than $140,000 in anticipated losses per $1 million over 30 years.
Federal Flood Insurance Gaps
The National Flood Insurance Program (NFIP) caps building coverage at $250,000 and contents coverage at $100,000, covering (at most) a quarter of the bill for a property with a rebuilding cost of $1 million. Between 2020 and 2024, the average NFIP claim paid $63,691 (the median was $20,272).
Any costs that exceed these limits must be covered by private excess flood insurance, homeowners policies that are subject to exclusions and deductibles, or personal savings. For luxury homeowners, the gaps can result in costly disputes over claims.
Temporary Housing Adds Significantly to Costs
If a home becomes uninhabitable after a disastrous event, a homeowner must also cover costs for alternative accommodation, often for months or years. Census Bureau Household Pulse Survey data reveals that around 3.3 million American adults had to move into temporary accommodation due to disasters during a single year. For one in four, the displacement period lasted more than six months (in some cases, the homeowner was unable to return to the original property).
NFIP policies don’t cover temporary housing or extra living expenses while repairs are being carried out, leaving flood victims without private coverage to cover the bill.
HUD’s fiscal year 2026 data puts median U.S. rent for a four-bedroom home at $2,752 a month, but rents in many luxury disaster markets are much higher. Nantucket averages $5,571 a month ($66,852 a year), while Santa Clara County averages $5,453. For San Mateo and Marin counties, the average is $5,391.
Extended rebuilds quickly push costs even higher. A year’s rent for a four-bedroom home can reach as high as $55,032 on Maui, $54,312 in Napa, and $52,704 in Sonoma. Two years of temporary housing could exceed $100,000 in all three counties. Yearly rent costs $45,312 in the Florida Keys and $46,500 in Riverside and San Bernardino counties.
These estimates are conservative and reflect typical rents as opposed to the luxury accommodation many million-dollar homeowners might look for. Combined with rebuilding expenses, a major disaster can lead to six-figure costs before repairs even begin. Ultimately, disputes over extra living expense coverage, policy limits, and how long a property remains uninhabitable can become significant battles regarding sizable insurance claims.
The Potential Nightmare of a Dream U.S. Home
America’s 5.99 million million-dollar homes are disproportionately susceptible to natural disasters, with 43.3% situated in high-loss counties and vulnerable to risks from earthquakes, wildfires, hurricanes, and flooding.
Rising rebuilding costs, limited flood insurance coverage, and expensive temporary accommodation costs exacerbate the financial impact. Ultimately, a dream home can quickly turn into a nightmare, leaving luxury homeowners facing not only an ocean or mountain view but also six-figure losses and costly insurance wrangles.
