Buying a Waterfront Home in Sewall's Point

You can stand in two Sewall's Point houses on the same afternoon, both on the water, both roughly the same size, both with a dock out back, and find a seven-figure gap between them.

The photos will not explain it. The listing sheet usually will not either.

What explains it is a short list of things that are hard to see and expensive to fix. Here is that list, in the order it tends to matter. If you are still deciding whether the town itself fits, start with our guide to living in Sewall's Point.

The short version

1. Which side of the peninsula you are on

Sewall's Point has water on three sides. The St. Lucie River runs the south and west edge. The Indian River runs the east edge. They meet at the southern tip.

Those are not the same body of water and they do not shop the same way.

The east side faces the Indian River and the Intracoastal channel. The west and south face the St. Lucie. Depth varies, exposure to weather varies, sunrise and sunset views are opposite, and the run to the inlet is different from each.

There is also the third category people forget: the interior. A meaningful share of Sewall's Point homes are not on the water at all. Those buyers get the town, the canopy, and the address without the waterfront price or the waterfront maintenance. For a lot of buyers that is the smarter buy, and nobody ever pitches it to them.

2. Depth at your dock, at low tide

"Deep water" is a phrase, not a measurement.

The only version of that claim worth anything is a real depth reading at your dock at mean low water. Not average. Not what the neighbor says. Low tide, at the dock, on that property.

The reason this matters so much here is that the difference between four feet and six feet at low tide is the difference between two entirely different boats. If you own a boat already, or you know what you plan to buy, we need that number before we start narrowing streets. It changes the list.

Get it verified. A survey, a sounding, or a walk with someone who knows the water. Not a listing adjective.

3. The bridges

Two bridges cross the river here on A1A. The Evans Crary Bridge on the Stuart side, and the Ernest Lyons Bridge on the Hutchinson Island side. The first bridges here opened in 1958. Before that, the peninsula was close to isolated.

They are fixed spans, with roughly 65 feet of clearance.

For the overwhelming majority of buyers, 65 feet is a non-issue. Center consoles, express cruisers, most sportfish, no problem.

Where it becomes the entire conversation is sailboats with tall rigs and larger yachts with tuna towers. If that is you, which side of the bridges your dock sits on and what your air draft is decides your whole search. Answer that first and you will save yourself three months.

Ocean access from Sewall's Point runs out through the St. Lucie Inlet. That inlet has a reputation among local boaters, and it earns it. Conditions there can be genuinely difficult, particularly for smaller boats and particularly on an outgoing tide against an east wind. It is not a reason to avoid the area. It is a reason to talk to someone who runs it regularly before you buy the boat.

4. The seawall

This is the one that catches people.

A seawall is a structure with a lifespan. On a peninsula where a lot of the waterfront was built out decades ago, plenty of those walls are original or first-replacement. They fail slowly, then all at once, and replacement is a serious number.

What to look for and ask about:

• Age of the seawall and whether it has ever been replaced or capped
• Cracking, bulging, or a lean toward the water
• Soil settling or sinkholes in the yard behind the wall, which is often the first real sign
• Whether there are permits on file with the town for past work
• Whether the wall is shared with a neighbor, and what the arrangement is

A marine contractor inspection on a waterfront purchase in Sewall's Point is not optional in our opinion. It costs a fraction of what it saves.

5. The dock itself

An existing, permitted, in-good-condition dock with a working lift is a real asset with a real replacement cost.

"Room to build a dock" is a project, and projects in a town with its own building department and its own permitting process take time.

Things worth confirming:

• Is the dock permitted, and are the permits on file
• What is the lift capacity, and when was it last serviced
• Pilings: age, condition, and whether they have been wrapped
• Power and water at the dock
• Whether any of it extends past the property line into a neighbor's riparian rights

6. Septic or sewer

This is the current, live issue in Sewall's Point, and almost nobody outside the town is tracking it.

Historically, homes here were on septic. The town has been running a septic-to-sewer conversion program, supported by state grant funding, converting parcels in the lower-lying areas to sewer service through Martin County Utilities. By late 2025 the sewer lines themselves were reported complete, with grinder pump installs still going in across lower-lying streets, including the Pineapple Lane to Oakwood Drive area and the Sewall's Meadow to Delano Lane area. The state grant behind the work set a June 2026 deadline. Connection has been reported as voluntary unless a septic system fails, at roughly $8,000 to $12,000 per connection. Ask the town where your specific street landed.

For a buyer, the practical questions are:

• Is this specific address on septic or on sewer today
• If it is on septic, is it in a phase area that is scheduled or eligible
• If it is eligible, what is the connection cost and who pays it, you or the seller
• If it is on septic and staying there, when was the system last inspected and pumped, and where is the drain field relative to any pool or addition you are planning

This has come up in negotiations and it will come up more. Ask the question early. If a seller does not know the answer, that is useful information too.

7. Flood zone, elevation, and insurance

On a peninsula that is roughly 71% water by area, this is not a footnote.

Get the flood zone and the elevation certificate before you get emotionally committed. Then get an actual insurance quote, not an estimate, on that specific address. Windstorm, flood, and homeowners, priced together.

Insurance in Florida has moved enough in the last few years that a quote from a friend's policy three years ago is not a guide to anything. And on a waterfront home, the insurance line can be large enough to change what price you can carry.

Roof age drives this too. On a town where a lot of the stock is older, roof age is frequently the single item that decides whether a carrier will write the policy at all.

One more thing: the trees

Sewall's Point requires a permit to remove a tree, and runs a Heritage Tree Program. That canopy is a big part of why the town looks the way it does, and it is protected on purpose.

If your plan involves a pool, an addition, a new driveway, or anything that means removing a mature tree, find out what the town will and will not approve before you close. This is a normal, workable process. It is just not a process most buyers know exists, and it does not exist the same way in an unincorporated area.

For sellers in Sewall's Point

The list above cuts both ways.

If you own here, the items on this list are exactly what a serious buyer's agent is going to poke at. Which means they are also the items that either support your price or quietly cost you money at the negotiating table.

Three things worth doing before you list:

1. Get the seawall and dock looked at. If they are in good shape, that is a documented selling point. If they are not, you want to know before a buyer's inspector tells you, because then you control how it gets handled.
2. Have the septic or sewer answer ready in writing. Whichever it is, know it and be able to prove it.
3. Have the depth number. At the dock, at low tide. A seller who can answer "how deep at my dock" with an actual number sells to boaters faster than one who says "deep water."

What Sewall's Point waterfront costs

The range in this town is wide, and it is wide for the reasons in this article.

Interior, non-waterfront homes trade in one bracket. Waterfront with a good dock and good depth trades in another. Estate waterfront at the confluence trades in a third that has very little to do with the other two.

The aggregator sites are unreliable here and disagree with each other by wide margins, because a single large closing swings the numbers in a town of fewer than 1,000 homes. We would rather send you the actual MLS picture: active count, median list, twelve-month closings, median sale, and days on market.

Common questions about buying waterfront in Sewall's Point

Does Sewall's Point have ocean access?
Yes, out through the St. Lucie Inlet. What varies by address is your depth at the dock, your route, and whether the fixed A1A bridges with roughly 65 feet of clearance are between you and open water.

Are the bridges in Sewall's Point fixed or drawbridges?
The A1A bridges, the Evans Crary and the Ernest Lyons, are fixed spans with roughly 65 feet of clearance. That works for the great majority of powerboats. Sailboats with tall rigs need to confirm air draft and which side of the bridges they are docking on.

Is Sewall's Point on septic or sewer?
Both, depending on the address. The town has been running a phased septic-to-sewer conversion with state grant support, connecting parcels in lower-lying areas to Martin County Utilities service. The sewer lines were reported complete in late 2025. Confirm the status and any connection cost for the specific property before you write an offer.

How deep is the water at Sewall's Point docks?
It varies significantly by street and by side of the peninsula. There is no single answer, which is exactly why the listing phrase "deep water" is not enough. Get a real depth reading at mean low water for the specific dock.

Do I need a permit to remove a tree in Sewall's Point?
Yes. The town requires a tree removal permit and runs a Heritage Tree Program. Factor this in if you are planning a pool, an addition, or major landscaping.

Can I buy in Sewall's Point without being on the water?
Yes, and a lot of buyers should. Interior homes get you the town, the canopy, and the address at a very different price, with no seawall and no dock to maintain.

What should I inspect on a Sewall's Point waterfront home?
Beyond a standard home inspection: a marine inspection of the seawall and dock, a verified low-tide depth reading, the septic or sewer status, roof age, the elevation certificate, and a real insurance quote on that address.
