Marina Homes — Hilton Head Island

Windmill Harbour stands apart on Hilton Head Island as the only private, inland deepwater marina community — a place where the boat slip is deeded alongside the home and the tidal creek is your backyard. Buyers searching for that specific combination deserve a guide built around the market, the process, and the details that matter before an offer is written.

On Hilton Head Island, 'marina access' means different things in different neighborhoods. At Windmill Harbour, it means a South Carolina Inland Waterway-connected marina with protected deepwater slips, a lock system that keeps water levels stable regardless of tide, and a residential community of single-family homes and villas that sits directly on the marina basin. That is a narrower and more specific asset than oceanfront, lagoon-front, or dock-on-creek properties elsewhere on the island — and it commands pricing and due diligence to match.

The buyers drawn to Windmill Harbour typically arrive with a boat already owned or on order, a clear-eyed interest in the cruising lifestyle, and questions the standard island buyer guide does not answer: How does the slip transfer work? What does the Windmill Harbour Community Association govern? Can the home be rented short-term? COAST brokered by eXp Realty has represented buyers across the Lowcountry's most specific waterfront niches, including marina communities, and this page addresses the questions that actually determine whether a Windmill Harbour home is the right acquisition.

What the Marina at Windmill Harbour Actually Is

Windmill Harbour is a gated community on the north end of Hilton Head Island, positioned along the Intracoastal Waterway. Its defining infrastructure is a lock-controlled marina basin — the lock separates the interior harbor from the waterway, stabilizing the water level inside the community and protecting vessels from tidal fluctuation. That engineering detail matters for boaters: it means calm, consistent water at the docks regardless of the Lowcountry's considerable tidal range.

The marina accommodates a range of vessel sizes, with slips available to community residents. Slip ownership and availability are governed by the Windmill Harbour Community Association (WHCA), not simply by the adjacent home deed, and the rules around slip transfer, rental, and sublease are specific to that governing document. Buyers should request and review the WHCA documents — covenants, conditions, and restrictions, slip ownership or lease records, and current HOA financials — before going under contract. South Carolina law requires sellers to provide HOA disclosure packages, and a buyer's agent at COAST brokered by eXp Realty will confirm that package is complete.

Where Marina Properties Sit Within the Hilton Head Market

Hilton Head Island's waterfront market segments across several distinct access types: oceanfront (Sea Pines, Palmetto Dunes, Forest Beach, Folly Field), lagoon-front (throughout Palmetto Dunes and Palmetto Hall), deepwater creek and sound-front (scattered across Port Royal Plantation and mid-island), and marina-basin (Windmill Harbour, and to a lesser degree Harbour Town in Sea Pines, where dock access is commercial rather than residential-deeded). Windmill Harbour is the island's clearest example of a community purpose-built around private marina infrastructure, which is why buyers searching specifically for a deepwater slip alongside a residential home consistently arrive there.

Harbour Town, in Sea Pines Resort, is frequently named alongside Windmill Harbour because of its iconic lighthouse and working marina, but Harbour Town's marina serves day visitors, charter boats, and transient vessels — not deeded residential slips. Sea Pines homeowners have access to South Beach Marina for some boating services, but that is a different arrangement from the Windmill Harbour model. Understanding that distinction is the first step in narrowing a marina-home search to properties where the slip is genuinely part of the residential ownership structure.

What Out-of-State Buyers Should Verify Before Closing

Buyers relocating from markets where HOA disclosures are minimal often underestimate the due-diligence scope in a Lowcountry gated community. At Windmill Harbour, the critical items beyond standard inspection and title work include: the WHCA governing documents and any amendments (particularly regarding slip assignment, transfer on sale, sublease rules, and vessel size restrictions); current HOA and marina association assessments and reserve fund status; whether a specific slip is included in the listing or sold separately; and the condition and category of the slip itself (floating dock, fixed pier, electrical and water service). South Carolina's real property disclosure requirements cover the home, but marina infrastructure is governed separately — your agent must know to ask.

Property tax in South Carolina is assessed at 4% of fair market value for a primary residence (owner-occupied, SC domicile) and 6% for secondary or investment property. For an out-of-state buyer maintaining another primary residence, the 6% rate applies until and unless SC domicile is established. That difference is meaningful at marina-home price points, and buyers should model both scenarios with a local CPA or tax advisor before making an offer. COAST brokered by eXp Realty can refer buyers to Lowcountry-based professionals with experience in exactly this calculation.

Short-Term Rentals, Long-Term Leasing, and the Windmill Harbour Covenant

Windmill Harbour is among the Hilton Head Island communities that prohibit short-term rentals under its community covenant — minimum lease terms (typically 90 days or longer) apply. This places Windmill Harbour in the same category as Hilton Head Plantation, Indigo Run, Long Cove Club, Palmetto Hall, Port Royal Plantation inside the gate, and Wexford: communities that prioritize residential stability over vacation-rental activity. Buyers whose acquisition thesis depends on short-term rental income should be directed instead to Forest Beach, Folly Field, Sea Pines, or Palmetto Dunes — communities where STR is permitted subject to the Town of Hilton Head Island's annual permit and business license requirements.

For buyers acquiring a Windmill Harbour home as a primary residence, second home, or long-term-rental asset, the STR restriction is not a barrier — it is part of the community's character. Long-term leasing of 90 days or more is generally permitted under the covenant, and the marina lifestyle tends to attract a tenant profile that values stability and access. Buyers considering any rental use should have their attorney or agent review the current WHCA covenants directly, since covenant amendments can change the terms, and the document — not marketing materials — governs.

Questions

Answered

Does a Windmill Harbour home come with a boat slip?
Not automatically — slip ownership or assignment is governed by the Windmill Harbour Community Association separately from the home deed, and availability varies by listing. Some listings include a deeded or assigned slip; others do not. Buyers should confirm slip status, slip number, governing documents for slip transfer, and any vessel size restrictions before going under contract. Your COAST brokered by eXp Realty agent will request this documentation as part of standard buyer due diligence.
Can I operate a short-term rental at Windmill Harbour?
No — Windmill Harbour prohibits short-term rentals under its community covenants, with minimum lease terms typically of 90 days or more. Buyers seeking short-term rental income should consider Forest Beach, Folly Field, Sea Pines, or Palmetto Dunes, where STR is permitted subject to the Town of Hilton Head Island's annual permit and business license process. Long-term leasing at Windmill Harbour is generally permitted under the covenant.
How does the Windmill Harbour lock system work, and why does it matter for boaters?
The marina basin at Windmill Harbour is separated from the Intracoastal Waterway by a lock, which equalizes water levels between the interior harbor and the waterway on a controlled schedule. This keeps dock water depth stable regardless of tidal stage — a meaningful operational advantage in the Lowcountry, where tidal range can exceed six feet. Boaters transit the lock on scheduled hours or by request; current lock hours and procedures are governed by the WHCA and should be confirmed before closing.
What is the difference between Windmill Harbour and Harbour Town for marina access?
Windmill Harbour is a residential community built around a private, lock-controlled marina basin where slips are associated with residential ownership and governed by the community association. Harbour Town, in Sea Pines Resort, features a working commercial marina that serves charter boats, transient vessels, restaurants, and day visitors — residential access to a deeded slip is not part of the Harbour Town home-ownership model in the same way. Buyers specifically seeking a residential slip alongside their home should focus their search on Windmill Harbour.
What property tax rate applies to a Windmill Harbour home purchased by an out-of-state buyer?
South Carolina assesses residential property at 4% of fair market value for an owner-occupied primary residence where the owner establishes SC domicile, and at 6% for secondary or investment properties. Out-of-state buyers who maintain their primary residence elsewhere will be assessed at the 6% rate until and unless they establish SC domicile. At marina-home price points, the difference between these two rates is substantial, and buyers should model both scenarios with a Lowcountry-based CPA before submitting an offer.
What HOA documents should I request before making an offer on a Windmill Harbour home?
At minimum: the WHCA Declaration of Covenants, Conditions, and Restrictions (including any recorded amendments); current HOA and marina association fee schedules and special assessment history; the reserve fund study and reserve fund balance; slip assignment records specific to the property; and marina rules governing vessel size, live-aboard restrictions, and sublease of slips. South Carolina law requires sellers to provide an HOA disclosure package, but buyers should verify it is complete and current. COAST brokered by eXp Realty will confirm all required disclosures are in hand before the inspection period closes.
Are there other marina-access communities on Hilton Head Island worth considering?
Windmill Harbour is the clearest example of a community purpose-built around a private residential marina basin. Elsewhere on the island, deepwater access takes different forms: deep-draft dock-on-creek properties in Port Royal Plantation and along Skull Creek, sound-front homes with private docks in various communities, and commercial marina access through Palmetto Bay Marina and South Beach Marina in Sea Pines. Each has distinct ownership, permitting, and access structures. A buyer with specific vessel requirements should have those parameters defined before touring — COAST brokered by eXp Realty can match the vessel spec to the right dock or slip type.
