Florida Keys Marine Structures

Custom Boathouses
Built for the Keys.

A boathouse in the Florida Keys has to do more than provide shelter — it has to withstand hurricane conditions, continuous saltwater exposure, and strict environmental regulations, while holding up for years. Aqua Pilings designs and builds boathouses and covered marine structures using materials and methods selected specifically for the Keys environment.

The Keys Difference

Not all boathouses
are built equal.

Building a boathouse in the Florida Keys involves constraints that most coastal construction does not. The coral rock substrate, constant saltwater exposure, and hurricane-force wind requirements all demand specific materials and construction techniques. On top of that, environmental regulations governing waterfront construction in the Keys are among the most detailed in the state — permits often involve Monroe County, FDEP, and federal review.

Every boathouse we build is designed around your specific property — the water depth at your dock, your lot lines, your vessel dimensions, and the applicable regulatory requirements for your location. No two projects are identical, and we do not treat them that way.

We handle the design, permits, and construction with the same crew throughout. When the project is complete, you have a structure that is built to code, properly permitted, and suited to the conditions of the Keys — not a generic coastal design installed by a crew that has never worked in this environment.

Engineered for Hurricane Conditions Framing, fasteners, and roofing systems specified to meet Keys wind load requirements — not standard coastal minimums.

Marine-Grade Materials Throughout Aluminum framing, concrete pilings, composite decking, and hardware rated for long-term saltwater exposure.

Designed for Your Property We assess your site, vessel, lot constraints, and permit requirements before drawing anything — no off-the-shelf solutions.

Full Permitting In-House Monroe County, FDEP, Army Corps, and HOA applications handled from drawings through final approval. You sign; we manage.

One Crew, Start to Finish No subcontractors. The same licensed team handles every phase of your project from site assessment through final walkthrough.

What We Build

Covered marine structures
for every property.

From single-slip covered structures to full boathouses with living space above, we build to your site requirements and budget. Each structure is custom designed for your property — not adapted from a standard plan.

Covered Boat Slips

A roofed structure over an existing or new dock slip — the most straightforward way to protect a vessel from sun, rain, and falling debris. Built with aluminum framing and roofing panels rated for Keys wind conditions.

Full Boathouses

Enclosed marine structures with full weather protection on three or four sides. Designed to accommodate specific vessel dimensions and provide complete protection from wind, saltwater spray, and storm conditions.

Davits & Gazebos

Davit systems for PWC and smaller vessels, and waterfront gazebo structures for outdoor living space at the water's edge — all constructed with saltwater-rated materials and built to Keys wind specifications.

Materials & Methods

Built to last in
a saltwater environment.

Standard construction materials fail quickly in the Florida Keys. Wood rots, standard steel corrodes, and hardware that works fine on the mainland degrades rapidly in continuous saltwater and high-humidity conditions. Every material we specify for a boathouse project is selected with the Keys environment in mind — not just for initial cost.

The result is a structure that holds up without constant maintenance and does not require early replacement. We would rather build it correctly once than see you dealing with repair costs in a few years.

Concrete pilings for structural foundation

Composite decking — no rot, minimal maintenance

Stainless steel and hot-dip galvanized hardware

Roofing systems rated for Keys wind loads

Common Questions

Boathouse questions
answered.

Questions we regularly hear from Keys property owners about boathouse construction, permitting, and what the process involves.

Call Us Directly

Who should consider building a boathouse in the Keys?

Waterfront property owners who want covered, dedicated storage and protection for their vessel — particularly those who keep a boat at their property year-round and want to reduce exposure to sun, rain, saltwater spray, and storm conditions. A boathouse is also a practical choice for owners who prefer not to pay ongoing marina slip fees.

When is the best time to plan and build a boathouse?

The dry season — November through April — is generally the best window for construction. However, planning and permitting need to start well in advance, as the regulatory process for waterfront structures in the Keys can take several months. We recommend beginning the conversation at least six months before your target construction date.

How is boathouse construction in the Keys different from other coastal areas?

The Keys have a combination of factors that most coastal areas do not: coral rock substrate that requires specific foundation methods, continuous saltwater and high-humidity exposure that eliminates many standard materials, hurricane wind load requirements that exceed most coastal building codes, and environmental regulations that govern what can be built over and adjacent to the water. Contractors without Keys-specific experience routinely underestimate these requirements.

Do you handle all the permits?

Yes. Boathouse construction in the Keys typically requires permits through Monroe County, FDEP, and in some cases the Army Corps of Engineers. We manage the entire process — drawings, applications, agency coordination, and follow-through to final approval. You sign where required; we handle everything else.

What areas do you serve?

We serve waterfront properties throughout the Florida Keys and South Florida — Key West, Stock Island, Big Pine Key, Marathon, Duck Key, Islamorada, Tavernier, Key Largo, Plantation Key, Key Biscayne, and the broader South Florida coastline. Reach out and we can confirm coverage for your specific location.
