A private dock behind the house is the reason most of my waterfront buyers are looking in Fort Lauderdale. The city has roughly 165 miles of navigable waterways and Port Everglades Inlet at its doorstep. But "private dock" on a listing tells you very little. Two homes on the same street can be completely different for boating.
I've been selling this coastline since 1995. Here's the checklist I walk every boating buyer through before they write an offer.
The Short Answer
Check six things, in this order:
- Usable dock length — frontage minus the side setbacks, not the frontage itself.
- Water depth at low tide — measured at the dock, not taken from the listing.
- Bridges on the route to the ocean — fixed bridges cap your boat's height.
- Canal width — whether you can turn the boat and get in and out without drama.
- Seawall condition and height — and whether it meets today's elevation rules.
- Permits — for the dock, lift and seawall.
The homes that combine deep water, a wide canal and no fixed bridges are the ones that carry the biggest premium — and hold it, because every future buyer with a boat wants them.
1. Dock Length — and Why Frontage Isn't Berth Size
As a rule of thumb, you want 10–15 feet more dock than boat for lines, fenders and safe boarding. A 30-foot boat wants about 40–45 feet; a 50-foot yacht about 60–65 feet.
The trap: 80 feet of waterfront does not mean an 80-foot boat. Fort Lauderdale requires docks and moored vessels to stay back from each side property line, so your usable berth is the frontage minus a setback on both sides. Each city sets its own rule — see our dock building rules by city. Corner and point lots, or lots on wide water, give you more room.
| Boat | Usable dock | Depth at low tide | Canal width |
|---|---|---|---|
| Jet ski / PWC | 20 ft | 3 ft | 30 ft |
| 20–35 ft center console / express | 45 ft | 5 ft | 50 ft |
| 35–60 ft motor yacht | 70 ft | 7 ft | 80 ft |
| 60–79 ft yacht | 90 ft | 8–9 ft | 100 ft |
| Superyacht (79–100 ft) | 115 ft+ | 10 ft | 120 ft+ |
| Large superyacht (100–199 ft) | Marina or wide-water estate | 12 ft+ | 150 ft+ / open water |
Rules of thumb for planning only. Depth figures assume your boat's draft plus a safety margin; confirm with your captain and a marine surveyor.
2. Water Depth at Low Tide
Depth decides the biggest boat the home can ever handle. Tides here swing roughly 2–3 feet, so a canal that looks fine at high tide can put you on the bottom at low tide.
- Under 5 ft: small boats, kayaks and paddle craft.
- 5–8 ft: most center consoles and express cruisers.
- 8 ft+: "deep water" — most yachts up to about 80 feet.
- 10–12 ft+: premium; what larger motor yachts need.
Leave at least a foot or more under the keel beyond your stated draft. And check the whole route, not just the dock — a shallow spot at the canal mouth matters as much as the depth behind the house.
3. Bridges and Ocean Access
Not every waterfront home reaches the ocean the same way:
- No fixed bridges: nothing between the dock and the inlet limits your boat's height. This is the premium category — much of the Las Olas Isles, Seven Isles, Harbor Beach and Rio Vista.
- Fixed bridge on the route: the lowest bridge sets the tallest boat you can own. Flybridges, towers, radar arches and sailboat masts are what get stopped.
- Drawbridges: no height limit, but you run on the bridge schedule.
- No ocean access: lakes and cut-off canals. Beautiful, but not a boating home.
Also look at which inlet you'll use. Port Everglades is a deep ship channel and handles any yacht. Hillsboro Inlet, which serves Lighthouse Point and Hillsboro Mile, is shallower and can be rough on an outgoing tide against an east wind — fine for most sportfish boats, but a real consideration for larger yachts.
On our listings, the ⚓ Route to the ocean button traces the water route from the dock, the inlet, distance, run time and the bridges along the way. If a listing says there's no ocean access, we don't show one.
4. Canal Width
A common guideline is about 2.5 times your boat's length to turn around comfortably. On a narrow canal, bigger boats back in or out and lean on thrusters. If you're running 40 feet or more, a canal under about 80 feet wide makes every trip a project. Wide water, turning basins and point lots are what large-boat owners pay up for.
5. Seawall Condition — and the New Height Rules
The seawall holds up your yard, your dock and, indirectly, your foundation. Warning signs: cracked or spalling cap, sinkholes or soil voids behind the wall, leaning panels and rust bleeding from the tie-backs.
There's also a newer issue buyers miss. Fort Lauderdale set a 3.9-foot NAVD88 minimum for new seawalls in 2016, and in 2023 adopted updated flood-resiliency standards aligned with Broward County's sea-level-rise model, which calls for higher tidal barriers (5.0 feet NAVD88) when walls are built or substantially repaired. The same rules added real-estate disclosure requirements. In plain terms: an older, low wall may have to be raised at its next major repair, not just patched. Ask for the wall's elevation, age and permit history.
Seawall repair and replacement is commonly priced by the linear foot and often lands in the six figures on a typical lot. That's negotiating leverage if you find it before closing.
6. Lifts, Power and the Dock Itself
- Lift capacity: must exceed your boat's wet weight — fuel, water and gear included.
- Lift width: wide-beam boats (about 14 ft+) often need a custom cradle.
- Shore power: 30-amp for small boats; 50- or 100-amp service for yachts running air conditioning.
- Materials: concrete and composite last; older wood decks and pilings need a close look.
The Pre-Offer Inspection, Step by Step
- Hire a licensed marine contractor or engineer — not just a home inspector.
- Inspect pilings at and below the waterline, and ask when they were installed.
- Check the seawall cap, face and backfill for cracks, movement and voids.
- Test shore power and dock lighting; ask whether it meets NFPA 303 and ABYC practice.
- Measure depth at the dock at low tide.
- Pull permits and final inspections for the dock, lift and seawall from the city.
- Read HOA rules on boat size, liveaboards and dock changes.
- Check the flood zone and ask about past flood claims and insurance cost.
The Costliest Mistakes I See
- Treating waterfront frontage as berth length.
- Trusting the listed depth instead of measuring at low tide.
- Forgetting to check bridges between the dock and the ocean.
- Skipping the seawall inspection — or not asking whether it meets current height rules.
- Inheriting unpermitted docks or lifts.
- Buying for today's boat when the next one will be bigger.
Where Boating Buyers Look
- Las Olas Isles — deep finger-island canals and the shortest run to Port Everglades.
- Seven Isles — gated, deep water, no fixed bridges.
- Harbor Beach — large estate lots, wide water, private marina and beach club.
- Rio Vista — no fixed bridges from most canals, via the New River.
- Coral Ridge — good value, but some canals sit behind fixed bridges. Verify each canal.
- Lighthouse Point — deep canals and big-boat culture, out Hillsboro Inlet.

Frequently Asked Questions
What is considered deep water in Fort Lauderdale?
Most buyers and captains treat 8 feet or more at mean low water as deep water — enough for most yachts up to roughly 80 feet. 10 feet or more is premium and is what larger motor yachts need. Under 5 feet limits you to smaller boats. Always measure at the dock at low tide; listing and county figures are often old.
Does 80 feet of waterfront mean I can dock an 80-foot boat?
No. Fort Lauderdale requires docks and moored boats to stay back from the side property lines, so the usable berth is the frontage minus a setback on each side. An 80-foot lot usually berths a boat noticeably shorter than 80 feet. Confirm the city's current setback rule and any neighbor or HOA limits for the specific lot.
What does 'no fixed bridges' mean?
It means there is no fixed (non-opening) bridge between the dock and the ocean inlet, so the height of your boat — flybridge, tower, radar arch or mast — is never limited. Opening drawbridges may still sit on the route and run on schedules. Always trace the actual route on a chart.
How high must a seawall be in Fort Lauderdale?
The city first set a 3.9-foot NAVD88 minimum for new seawalls in 2016, then adopted updated resiliency standards in 2023 aligned with Broward County's sea-level-rise model, which calls for higher tidal barriers (5.0 feet NAVD88 in the county model) when walls are built or substantially repaired. An older, low wall can therefore mean a required raise at your next major repair. Ask the seller for the wall's elevation and permit history.
Are private docks regulated in Fort Lauderdale?
Yes. Docks, boat lifts and seawalls need city building permits, and work on the water often also needs Broward County environmental approval, the Florida DEP and sometimes the U.S. Army Corps of Engineers. Unpermitted structures can become the buyer's problem, so request permits and final inspections during due diligence.
Is a seawall inspection really necessary?
Yes. A standard home inspector doesn't evaluate seawalls. A licensed marine contractor or engineer can spot cracked caps, voids behind the wall, leaning panels and failing tie-backs. Seawall replacement is commonly a six-figure job, so find out before closing — it's leverage for a credit or repair.
