Selling a waterfront home is one of the most detail-heavy moves in Greenwich, CT real estate, and the water side of the sale is where surprises tend to hide. A generic checklist will not tell you how Connecticut's coastal rules apply to a home on the waterfront or tidal areas in Greenwich.  You are going to need a seasoned Realtor and a team of expert advisors to work with you as a team. 

I have lived in Greenwich for more than 50+ years and have helped numerous clients buy and sell here since 1985. For many waterfront owners, selling is part of a major life transition. My job is to make sure nothing about the water side of the sale catches you or a buyer off guard.

What makes selling a waterfront home different?

The water is the reason buyers want your home, and it is also the part they will examine most closely. A waterfront sale goes smoothly when you can answer three questions before a buyer asks them: what water access comes with the property, what the flood picture looks like, and what condition the shoreline structures are in.

Your water access. In Connecticut, docks, floats and other structures in tidal and coastal waters are regulated by the Department of Energy and Environmental Protection (DEEP). Even adding a float to an existing dock requires a permit, and moorings are authorized through the harbor master. A buyer's attorney will ask whether your dock was permitted. A permitted dock is a real asset. One with unclear records can become a negotiating point late in the sale. Find your permits now, and if you cannot, raise it with your attorney early.

Your flood picture. Connecticut's Residential Property Condition Report asks sellers about flood zone status, flood insurance and any federal assistance received for flood damage. Since July 1, 2026, Connecticut mortgage lenders must give borrowers a signed, plain-language flood insurance notice at least 10 days before closing on most one-to-four family purchases and loans, whether the property sits in a mapped flood zone. This is a good moment for buyers near Long Island Sound, the Mianus River or the Byram River to ask their insurance agent about a flood insurance quote early. Buyers need to pay closer attention as a result. Sellers locate your flood insurance declarations, any elevation certificate, and a record of past water events and the improvements you made afterward.

Your shoreline structures. Seawalls, bulkheads and stairs to the water will be inspected, sometimes by a specialist. Work along the shoreline generally requires state and town review, which takes time. Starting a major repair right before listing is rarely wise. An engineer's assessment you can share with buyers often serves you better.

Why are waterfront properties different? Because the Town of Greenwich requires permits and land use review for any work done on or near the water. It might require State of Connecticut review also. Buyers planning changes will want to understand what may be possible, and they should hear that from the right professionals rather than from assumptions.

What should I gather before listing a Greenwich waterfront home?

Having these ready before the first showing puts you in a stronger position and shortens the back-and-forth once you have a buyer:

• Permits for your dock, float, seawall and any past work near the water

• A current survey showing your property along the waterline

• Flood insurance declarations and any elevation certificate

• A written history of any water events and the improvements made afterward

• Service records for major systems, especially anything that has been raised or protected from flooding

• Any engineering reports on seawalls or bulkheads

How do I decide when it is time to sell after decades on the water?

For most people, selling a waterfront home is not a market decision. It is a life decision: being closer to children and grandchildren, spending more of the year somewhere else, or starting a chapter that looks different from the last one. I encourage clients to start with that picture and work backward to the sale.

A few practical points help. Plan the timing of your next home before you list, so you are never rushed into either decision. If family members share in the decision, bring them in early. And speak with your CPA, because a home owned for many years can carry a significant gain.

Frequently asked Questions

How do I know if my dock is permitted?
Start with your own records and the paperwork from when you bought the home, then check with CT DEEP, which regulates structures in tidal and coastal waters. If the records are unclear, raise it with your attorney before listing, because a buyer's attorney will ask.

Do I have to disclose flooding when I sell a home in Connecticut?
Yes. The Residential Property Condition Report asks about flood zone status, flood insurance and federal flood assistance. Since July 1, 2026, Connecticut lenders must also give buyers a written flood notice before closing. Honest, well-documented answers protect you and keep the sale on track.

Should I repair my seawall before I sell?
Not automatically. Shoreline work generally requires state and town review and can take months, so for many sellers an engineer's assessment shared with buyers is the better path. The right answer depends on the wall's condition and your timeline.

Can a buyer add a dock or expand a waterfront home in Greenwich?
It is never guaranteed. New docks and significant work near the water are reviewed by the state and by the Town of Greenwich, and a new owner may not be allowed to build what a neighbor has. Buyers should confirm what is possible with the appropriate professionals before relying on it.

When should I start preparing to sell a waterfront home?
Earlier than you would for an inland home, ideally several months ahead. Finding permits, surveys and flood documents, and getting any engineering assessments, takes time. Having them ready before buyers ask puts you in a stronger position.
