Is your perfect Key West day one where you step from your veranda to a private ferry and end at a quiet beach, or one where you stroll to dinner and music along historic streets? If you are choosing where to anchor your life in Key West, you are likely weighing two icons: secluded Sunset Key and lively Old Town. Both deliver the island you love, yet the daily rhythm, access, and rules feel very different. In this guide, you will see how the two compare so you can match your lifestyle to the right address. Let’s dive in.

Quick snapshot: Sunset Key vs. Old Town

Sunset Key is a privately managed, 27-acre island community and resort a few hundred yards off Old Town’s harbor. The island experience centers on privacy, curated amenities, and boat-only access, with services framed by the on-island hospitality team. You can see the island’s setting and amenities on the operator’s page for Sunset Key Cottages, and the island’s size and history are summarized on the Sunset Key reference page.

Old Town is Key West’s historic core, formally recognized as the Key West Historic District and listed on the National Register. It is compact, walkable, and full of preserved architecture, museums, and public life. Learn more about the district’s character and boundaries from the Key West Historic District overview.

Privacy and community character

Sunset Key feels like a small, controlled-access neighborhood surrounded by water. Daily life is quiet and resort-like, with staff, ferry transfers, and house-by-the-beach calm. The tradeoff is that spontaneous errands or strolls into town require a quick boat ride. The operator frames the island as an exclusive, self-contained environment, which many second-home owners appreciate for low-maintenance living and privacy. Review the amenity and service approach on the island’s resort page.

Old Town offers a classic Key West street life. You get porches, pedestrians, galleries, and easy access to restaurants and cultural venues. Privacy is lower in exchange for convenience and variety. If you like to be out and about on foot, Old Town’s neighborhood scale favors you.

Access and day-to-day logistics

For Sunset Key, all access is by boat. The island’s ferry and restaurant shuttles depart near Opal Key on Front Street and run a short, single-digit-minute ride each way. For a sense of logistics and dock location, read the transfer details on the Latitudes reservation page. Boat access is part of the charm, but you will want to confirm schedules, guest policies, and delivery procedures with the island operator during due diligence.

Old Town is car-and-pedestrian friendly, but parking is limited. You will find a mix of metered street parking, municipal lots, and a City residential permit program. If you expect to drive daily or host frequent guests, plan for permits and seasonal congestion. This Key West parking guide gives a helpful overview of meters, residential permits, and garage options.

For emergencies and services, boat-only access on Sunset Key means response and heavy-item logistics operate differently than a standard in-town lot. Confirm the island’s emergency plans, utility arrangements, and waste removal with management. City resources cover broader emergency guidance and building FAQs, which you can review on the City of Key West site.

Architecture, preservation, and renovation rules

If you buy in Old Town, exterior work usually requires Historic Architectural Review Commission (HARC) approval and a Certificate of Appropriateness. Interior changes still need permits, and certain buildings must meet milestone inspection rules. These steps protect the district’s character and add time to projects. Get familiar with process expectations through the City’s HARC and building department FAQs.

On Sunset Key, architecture leans coastal-resort cottage and single-family homes in a unified landscape. Expect recorded covenants and island management guidelines that shape exteriors and operations. Request HOA and CC&R documents during due diligence so you understand design standards, maintenance allocations, and any use restrictions.

Amenities and lifestyle

Sunset Key delivers a near-resort lifestyle: private beach, zero-entry pool with pool bar, spa services, tennis, and the on-island restaurant Latitudes, supported by staff and housekeeping options. The experience is curated to feel seamless for owners who want privacy and service. Explore the amenity mix and service philosophy on the Sunset Key Cottages page.

Old Town is the heartbeat of Key West. You are minutes from Duval Street, Mallory Square, museums, galleries, and a wide mix of dining and nightlife. The variety is unmatched, and daily errands, workouts, and cultural outings are all on foot. See a high-level overview of this environment in the Key West Historic District summary.

Ownership, use rules, and short-term rentals

Whether you buy on Sunset Key or in Old Town, verify key documents early:

• Title and deed: Check for easements and any waterfront or dockage rights if you are a boater. Use the Monroe County Property Appraiser to pull parcel records and ownership history.
• HOA and management: Request recorded CC&Rs, recent HOA minutes, reserve studies, and assessment history for Sunset Key properties or Old Town condos and townhomes. The island operator’s page provides a sense of management and amenities for Sunset Key.
• Short-term rentals: Key West enforces permitting, inspection, and tax rules for transient rentals that can vary by property and zoning. If you plan to rent, confirm current requirements and any historic-district overlays with the City’s official FAQs.
• Building permits and inspections: Ask the City for any open or expired permits, code cases, and milestone inspection status. HARC approval applies to exterior work in the historic district.

Flooding, sea level rise, and insurance

Key West is low-lying and exposed to tidal flooding, storm surge, and long-term sea-level rise. For either location, order a current elevation certificate, confirm the parcel’s FEMA flood-zone designation, and secure quotes for homeowner, wind, and flood insurance. The City outlines floodplain basics and building rules in its FAQ resource, and NOAA’s Sea Level Rise Viewer helps you visualize future scenarios. Expect higher premiums and elevation requirements in AE or VE zones, and plan for mitigation such as elevating equipment or improving drainage.

Market and investment lens

• Supply and scarcity: Sunset Key is a finite, 27-acre island with limited parcels. That scarcity often supports a premium for privacy and resort integration. Old Town offers a wider range of property types and generally broader buyer demand. For current inventory and sales, pull comps through your broker and confirm parcel facts with the Property Appraiser.
• Rental potential: Old Town near the core often sees strong short-term demand due to proximity to attractions. Sunset Key can command exclusivity-driven rates if rentals are allowed by the HOA, but guest logistics follow island rules and ferry schedules. Always verify rental eligibility and local permits before assuming income.
• Resale: Sunset Key appeals to a narrower, privacy-seeking pool comfortable with boat access. Old Town speaks to a diverse set of buyers who want central convenience and historic charm. Your time to sell and marketing strategy will vary by property and audience.

Due-diligence checklist

Use this quick checklist to protect your purchase:

• Pull parcel records, legal descriptions, and tax history from the Monroe County Property Appraiser.
• Request HOA and CC&R documents, recent meeting minutes, reserve studies, and assessment history for the property.
• If boating matters, confirm dock, marina, or mooring rights in writing and request any applicable agreements.
• Ask the City for permit history, open or expired permits, and any code enforcement. If in Old Town, confirm HARC jurisdiction and process via the City FAQs.
• Order an elevation certificate, verify FEMA flood-zone status, and review NOAA’s Sea Level Rise Viewer for planning.
• Obtain homeowner, wind, and flood insurance quotes, and budget for mitigation.
