Retiring in Key West, Florida

The southernmost city in the continental United States, a genuinely walkable historic Old Town island community with no trauma center of its own, a single evacuation road, and some of the highest homeowners and flood insurance costs in Florida.

A genuinely walkable, historic island city at the end of the road, appealing to retirees who want Old Town’s compact charm and a real island lifestyle while accepting no trauma center, limited traditional beaches, and some of Florida’s highest insurance costs.

Part of the The Florida Keys region.

Golf
Not a defining recreational amenity on the island; retirees seeking golf typically look toward the Middle or Upper Keys or the mainland.
Waterfront
Genuine, though limited relative to mainland Florida given the island’s small footprint; Sunset Key and select Old Town-adjacent parcels offer direct water access, while most of the island’s recreational water access runs through public parks and marinas rather than private waterfront lots.
55+ housing
No large-scale dedicated 55-plus development was identified as a defining feature of Key West in this research; retirees are broadly distributed throughout Old Town, Truman Annex, and the island’s newer developments.
Walkability
Old Town Historic District is described as one of the most walkable destinations in Florida, given the island’s compact roughly 4-by-2-mile footprint, connecting the Hemingway Home & Museum, the Truman Little White House, and the Southernmost Point buoy within a genuine walking or bicycling radius.

Key West sits at the end of the 113-mile island chain, a compact roughly 4-by-2-mile island whose Old Town Historic District is described as one of the most walkable destinations in Florida, anchored by the Hemingway Home & Museum, the Truman Little White House, and the Southernmost Point buoy. Lower Keys Medical Center, an HCA-affiliated acute-care hospital with 33 medical specialties, serves as the island’s primary healthcare facility, but it holds no trauma-center designation; critical trauma patients are transported by helicopter, typically a 50-to-55-minute flight, to one of three Miami-Dade Level I trauma centers, most commonly Ryder Trauma Center at Jackson Memorial Hospital. Key West carries genuinely limited traditional beach access compared with mainland Florida coastal cities, relying instead on Smathers Beach, Fort Zachary Taylor Historic State Park’s snorkeling, and the remote, ferry-or-seaplane-only Dry Tortugas National Park roughly 70 miles offshore. US-1, the Overseas Highway, is the sole road connecting the entire island chain to the mainland, and Florida’s stated hurricane-evacuation policy requires local governments to maintain no more than a 24-hour clearance time for permanent residents, with mandatory evacuation triggered once a storm reaches Category 3 because no shelter in the Keys is certified for anything stronger than Category 2. Reported homeowners insurance in Key West averages roughly $9,835 per year, among the highest in Florida, and Monroe County’s Rate of Growth Ordinance (ROGO) caps new residential building permits countywide, a structural constraint on housing supply that applies to Key West alongside its own limited buildable land and historic-preservation rules.

Who Key West Tends to Fit

  • Retirees who want a genuinely walkable historic downtown, with Old Town’s compact grid connecting the Hemingway Home, Truman Little White House, and Southernmost Point
  • Those drawn to a real island lifestyle with deep diving, snorkeling, and fishing culture, including access to the remote Dry Tortugas National Park
  • Buyers interested in a gated, historic community option via Truman Annex, a 45-acre former naval station now HOA-governed with a rental cap
  • Those who want direct commercial-airline access via Key West International Airport (EYW), which completed a new terminal in April 2025 and added Avelo Airlines service in November 2025
  • Retirees comfortable with, and prepared for, Monroe County’s uniquely high homeowners, wind, and flood insurance cost structure as a real, ongoing cost of island living
  • Those who want a genuinely low municipal-scale, walkable retirement setting rather than a sprawling car-dependent city
  • Buyers drawn to a genuinely distinctive literary and cultural heritage, anchored by the Hemingway Home and an active gallery district along Duval and White Streets
  • Those who want the flexibility of a private-island living option via Sunset Key, accessible only by launch, at the very top of the local luxury market

Who May Prefer Somewhere Else

  • Buyers who want a trauma center within their own city — Lower Keys Medical Center holds no trauma designation, and critical patients require a roughly 50-to-55-minute helicopter flight to Miami-Dade
  • Those who want a single, low-cost evacuation route — US-1 is the sole road off the island chain, and mandatory evacuation triggers at Category 3 given the lack of any stronger-storm-rated shelter in the Keys
  • Retirees wanting a single reliable homeowners-insurance figure — Key West’s reported average around $9,835/year is itself one of many Keys-wide estimates that can range further depending on construction, elevation, and flood zone
  • Buyers who want traditional white-sand barrier beaches as a daily amenity — Key West’s beach access is genuinely more limited than most other Florida coastal retirement markets researched
  • Those who want abundant new-construction inventory — Monroe County’s ROGO permit cap and Key West’s own limited buildable land and historic-preservation rules constrain new housing supply significantly
  • Retirees wanting certainty on Lower Keys Medical Center’s exact licensed bed count, which was not independently confirmed via a direct primary-source check in this research
  • Those who want a genuinely quiet, low-tourism setting — Key West’s economy and daily street life are heavily shaped by a large, constant visitor population
  • Buyers wanting a single confirmed median-price figure, since Key West’s reported figures varied across different trailing-window statistics from the same data source

Housing Market

Median sale price: $1,049,306 (as of 2026).

Old Town offers a traditional grid of individually owned historic homes, generally not HOA-governed, while Truman Annex offers a gated, HOA-managed 45-acre former naval-station community with its own rental cap, both within genuine walking distance of downtown.

Concentrated in newer developments and gated compounds rather than Old Town’s traditional historic single-family grid; Sunset Key offers a private-island, launch-access alternative at the higher end of the market.

Genuinely limited, constrained by Monroe County’s Rate of Growth Ordinance permit cap, the island’s finite buildable land, and Key West’s own historic-preservation rules; recent activity centers on affordable/workforce housing projects like the Lofts at Trumbo and Garden View Apartments rather than open-market inventory.

Property Taxes & Homestead

Monroe County’s countywide millage held at roughly 2.6929 mills for FY2025-26, with an aggregate millage of roughly 3.3975 for FY2026-27, an increase of about 7.45% over the prior year; Monroe County is frequently cited as having one of the lowest county millage rates in Florida, though high assessed property values still produce a high total dollar tax bill for many owners.

Standard Florida homestead exemption (up to $50,000 off assessed value) and the Save Our Homes 3%/CPI annual assessment-growth cap apply to primary residents, with the filing deadline always March 1 of each year.

Insurance, Flood & Hurricane Risk

Key West homeowners insurance averages roughly $9,835 per year, cited as one of the highest rates in Florida; Keys homeowners typically need three separate policies (standard homeowners, private windstorm, and flood) because standard carriers largely exclude wind and flood coverage in this zone, with combined annual totals commonly running $8,000 to $13,000 and reported extremes reaching $30,000-plus depending on construction age, elevation, and flood zone.

Monroe County properties fall mainly in FEMA Zone AE (inland, lower relative risk) or Zone VE (direct coastal, wave-action exposure, highest risk), with a minimum lowest-floor elevation of Base Flood Elevation plus one foot required for qualifying structures; Florida law is phasing in mandatory flood insurance based on replacement cost, moving toward requiring coverage on all structures regardless of value by January 2027, a genuinely significant near-term cost consideration for Key West buyers.

Hurricane Irma made landfall in the Florida Keys on September 10, 2017 as a Category 4 storm with 132 mph sustained winds; Key West itself was relatively spared by a last-minute northward wobble in the storm’s track, with roughly 18 inches of surge above roadway on Atlantic Boulevard versus the roughly 5 feet that had been forecast, while the worst structural damage concentrated further north between Cudjoe Key and Marathon; Keys-wide, an estimated 25% of homes were destroyed or severely damaged and more than 4,000 homes were destroyed or badly damaged.

Monroe County properties fall mainly in FEMA Zone AE or Zone VE, and Florida’s statewide mandatory flood insurance phase-in is moving toward requiring coverage on all structures regardless of value by January 2027; buyers should obtain an individual flood-zone determination for any specific Key West address given how significantly risk and required elevation vary by location on the island.

HOA, CDD & Condo Fees

Truman Annex operates as a gated, HOA-managed historic community with its own city-imposed rental cap; Sunset Key operates as a private-island community accessible by launch; most of Old Town’s traditional historic single-family grid is not HOA-governed.

No Community Development District was identified within Key West in this research; the island’s governance structure centers on city and county authority alongside individual HOA-governed compounds like Truman Annex.

Healthcare

  • Lower Keys Medical Center — An acute-care hospital with 33 medical specialties and 63 practicing physicians. Exact licensed bed count was not independently confirmed in this research. Holds no trauma-center designation; critical patients are transported by helicopter to Miami-Dade Level I trauma centers, a flight of roughly 50 to 55 minutes.

Airports & Transportation

  • Key West International Airport (EYW) — approximately 2 miles
  • Miami International Airport (MIA) — approximately 159 miles (~241 min drive)

Key West participates in the broader statewide October-through-April snowbird pattern, with Florida’s population rising by up to roughly 5% during the winter season, though no Key West-specific seasonal traffic statistic was independently confirmed in available research; the island’s tourism-driven economy and single-road geography make seasonal and event-driven congestion a well-known local pattern.

Lifestyle

Golf is not a defining recreational amenity on the island itself; retirees seeking golf typically look toward the Middle or Upper Keys or the mainland.

Key West carries a deep, genuine boating, diving, and sportfishing culture, with charter operations serving both the nearshore reef tract and the remote Dry Tortugas National Park roughly 70 miles offshore, reachable only by ferry or seaplane.

Old Town Historic District is described as one of the most walkable destinations in Florida, given the island’s compact roughly 4-by-2-mile footprint, connecting the Hemingway Home & Museum, the Truman Little White House, and the Southernmost Point buoy within a genuine walking or bicycling radius.

The Studios of Key West anchors an active gallery and arts district along Duval and White Streets, complementing the island’s deep literary history tied to the Hemingway Home & Museum and its broader historic-preservation identity throughout Old Town.

Snowbird vs Full-Time

Key West participates in the broader statewide October-through-April snowbird pattern, with Florida’s population rising by up to roughly 5% during the winter season, though no Key West-specific seasonal population multiplier was independently confirmed in available research.

Compare Key West

Key West vs Marathon for Retirement: Walkable Historic City vs Middle Keys Hub Compared

Key West and Marathon anchor opposite ends of the practical Florida Keys retirement decision, roughly 47 miles apart along the same single-road US-1 corridor. Key West offers a genuinely walkable historic Old Town core, direct commercial-airline access, and a real cultural and literary identity, but sits at the very end of the island chain, farthest from mainland Miami trauma care. Marathon sits roughly halfway between Key Largo and Key West, offering more natural beach access via Sombrero and Coco Plum beaches and a rebuilding Baptist Health hospital campus, but carries a documented history of the most severe Hurricane Irma structural damage anywhere in the Keys and has no scheduled commercial airline service. Neither city has a trauma center; both rely on the same Keys-wide pattern of helicopter transport to Miami-Dade Level I facilities for critical care. Housing costs run genuinely high in both markets, with Marathon’s reported median actually running higher than Key West’s in the research reviewed, a reversal of what many buyers might expect given Key West’s larger population and tourism profile. The practical choice tends to come down to whether a buyer wants Key West’s walkable historic-city lifestyle and direct air access, or Marathon’s more natural, mixed-generation community character and central Keys position.

Nearby Places to Compare

  • Marathon

    The Middle Keys’ primary hub, home to a rebuilt Baptist Health hospital campus following severe Hurricane Irma damage, Sombrero and Coco Plum beaches, and the historic Old Seven Mile Bridge, with the same single-road evacuation constraint as the rest of the Keys.

  • Big Pine Key

    The unincorporated Lower Keys anchor community and home of the National Key Deer Refuge, sitting almost exactly between the region’s two hospitals in Marathon and Key West — a genuinely quieter, more residential alternative to Key West’s density and Marathon’s commercial core, in the specific stretch of the Keys that took the single most severe concentration of Hurricane Irma’s 2017 structural damage.
