How Much Does a Boat Dock Add to Home Value? The 2026 Data

Say you found two similar homes a few blocks apart, both on a navigable canal you can run a boat out of. One has a dock. One doesn't. How much more should you expect to pay for the one with the dock? We went looking in closed sales, and homes with a dock sold for about 8% more per square foot across South Florida, roughly 16% more in the Florida Keys, and close to even in Miami-Dade. Where you're buying changes everything.

If you've been reading other articles on this, you've probably seen a confident number like "a dock adds 20%." We didn't want to repeat someone else's stat, so we ran our own. And the honest answer is more useful than a single percentage, because it depends a lot on which market you're shopping.

How We Got the Number

Here's the thing that trips up most "dock adds X%" claims: dock homes usually sit on nicer water in pricier neighborhoods. So if you just line up dock sales against no-dock sales, you're really measuring the zip code, not the dock.

We fixed that by comparing neighbors. For every home that sold with a dock, we pulled the no-dock homes that sold within a mile, on the same kind of navigable water, and looked at price per square foot. Same area, same ocean access, the only real difference being the dock. We tossed out lakefront and dead-end no-access canals on both sides, since you can't get a boat to open water from those anyway.

Dock homes sold for 54% more overall. Compare them to the house down the street, though, and the gap shrinks to about 8%.

That gap between 54% and 8% is the whole point. The navigable water is what you're really paying a premium for. The dock adds a real, meaningful layer on top of that, but it's a smaller number than the internet wants you to believe.

The Premium Isn't the Same in Every Market

Here's where it gets interesting. The 8% average hides three very different markets.

Miami-Dade surprised us. A dock barely moved the needle. The reason is that Miami-Dade waterfront price per square foot is mostly land value, luxury, and Biscayne Bay views. A big share of those sales are teardowns, where the buyer is paying for the lot and the water and plans to bulldoze the house and the dock with it. On a teardown, the dock is worth nothing. It's coming out.

Broward is the cleaner picture, and probably the most useful number for a typical buyer. Lighthouse Point, the Las Olas Isles, the canal grid off the Intracoastal: these are neighborhoods full of working boaters, and the data says they pay about 12% more for a home that already has a dock.

Why the Keys Pays the Most

The Keys gap is the highest, and one caveat up front: it rests on about 90 matched homes, a smaller sample than Broward or Miami-Dade, so read it as directional rather than precise. That said, two forces would plausibly push it up down there.

First, scarcity. Building a new dock in Monroe County is genuinely hard. Mangrove-protection rules and dock permitting get in the way, so a home with an existing permitted dock may hold something a no-dock home next door can never add. The listings hint at it: Keys listings mention grandfathered docks and mangroves about ten times more often than mainland listings do, and a quarter of Keys waterfront listings lead with the dock as a headline feature, versus under 2% on the mainland. That is a correlation, not proof, but it lines up with the scarcity story.

In the Keys, you can't always build a dock. An existing permitted one is harder to replicate, and that tends to get paid for.

Second, demand. In the Keys, boating is much of the point. A waterfront home you can't keep a boat at is a weaker product there than in Miami, where plenty of buyers want the view and never plan to own a vessel. Scarce supply, motivated demand. That is the likeliest reason the Keys number runs high.

Which Dock Features Actually Matter

The premium isn't a flat figure stamped on every dock. What you have changes what it's worth, and the order of importance is consistent across every market we looked at.

Ocean access is the whole ballgame

A dock behind three fixed bridges with seven feet of clearance is close to useless for anyone running a 36-foot center console. A dock with a clean Intracoastal route and no bridges to the inlet is worth dramatically more. Bridge-free, deep-water access is the single biggest swing factor, which is exactly why it carries the most weight in our scoring.

The seawall, the dock, the lift

After access, buyers look at what's actually built and what shape it's in. A solid seawall, a real dock, and a working boat lift each add to what you can do with the property on day one. A failing seawall does the opposite. If the cap is cracking or the wall is bowing, the buyer sees a big repair bill coming and knocks it off the offer. So the gear matters, but condition matters just as much as having it.

Room to actually use it

A dock is only worth what your boat can do from it. How big a boat fits, how wide the canal is to back out and turn around, whether you can get to open water without waiting on a drawbridge. Wider canals and bigger slips are worth more because they fit more boat. Add the little stuff, shore power and fresh water at the dock, and you've got a setup someone coming out of a marina slip will happily pay for. None of it beats ocean access. All of it adds up.

How DockScore™ Fits In

DockOnly's DockScore™ takes everything above and rolls it into one number from 0 to 100, so you can compare two listings without becoming a marine surveyor. It weighs the things this article is about, ocean access first, then how usable the dock setup is and how big a boat the spot can really handle. Higher scores go to the homes with the kind of water and dock potential buyers actually pay up for.

One thing worth knowing: DockScore™ rates potential, not the current condition of the wood. A lot on deep ocean-access water can score high even before anyone builds a dock, because the expensive, hard-to-get part, the water and the permitting position, is already there. It won't tell you whether the seawall is cracking. That's what an inspection is for. What it gives you is a fast, consistent read on which listings have the bones worth chasing. A high score isn't just a nicer afternoon on the boat. It's a head start on resale, because the next buyer wants exactly what you want now.

An Honest Word on the Numbers

A few caveats, because we'd rather you trust the rest. We sorted homes by what the seller disclosed in the MLS, and that cuts both ways. Our "no dock" group means no dock was disclosed, not a guarantee the home has none, so some no-dock homes probably do have a dock, which would shrink the gap. At the same time, sellers tend to advertise their better docks, so the "dock" group likely skews toward nicer setups, which would widen it. We also didn't control for square footage, age, renovations, or view. So treat 8% as a solid directional read, not a precise appraisal adjustment. It tells you the dock is worth real money; it doesn't set the exact figure on your specific house.

We also report medians, not averages, on purpose. Waterfront teardowns throw off insane per-square-foot averages, and one $40,000-a-foot lot can wreck a mean. The median is the number that describes the typical sale.

The Bottom Line

If you're selling, get your paperwork together before you list. A current seawall inspection, your dock permits, and photos of the lift in operation cost you almost nothing and quietly protect your price when the buyer's agent goes looking for reasons to negotiate.

If you're buying, know which market you're in. In Broward and the Keys, an existing permitted dock is worth paying up for, especially in the Keys where you may never get to build one. In Miami-Dade, don't overpay for a dock at the median; the water is what you're buying. Either way, search dock homes on DockOnly and sort by DockScore™, so the premium you're paying is backed by boating you'll actually use.

Methodology: DockOnly analysis of closed single-family waterfront sales in Miami-Dade, Broward, and Monroe Counties, from 2023 through the latest available 2026 sales, sourced from the Miami MLS. We classified dock presence from seller-disclosed MLS data, restricted both groups to navigable ocean-access water, and matched each dock home to nearby no-dock sales within one mile (median price per square foot, three or more comps required). Because we compare medians of real closed sales, these are solid market-level figures. They control for location but not for every home-specific factor like size, age, or renovation, so use them to understand what a dock is worth in a given market, not as an exact appraisal of one address. The Keys number draws on a smaller pool of about 90 matched homes, so it is the least precise of the three, but it points clearly in the same direction.
