Patio Lanais & Sunrooms in Jupiter, FL
Jupiter homeowners build near salt air, wind-driven rain, and in some areas flood-zone rules, so a patio enclosure here has to be designed for the coast, not just for shade. Preventive Maintenance builds insulated aluminum lanais, conventional wood-and-concrete lanais, and air-conditioned additions in Jupiter. We handle the plans, permits, and common HOA notices, and every project starts with an inspection of your slab, roof, and tie-in.
Key Takeaways
What building near the water means in Jupiter
Jupiter sits at the northern end of Palm Beach County, close to the Atlantic and the Intracoastal. That shapes four things we check on every job.
Salt air. Coastal air wears down hardware faster than inland air. We specify aluminum framing and corrosion-resistant fasteners, and we look closely at flashing and sealant details, since small leaks near the coast turn into bigger problems quickly.
Wind-driven rain. Summer storms here often push rain sideways. Roof edges, glass seals, and drainage matter more than the look of the finished room.
Flood zones. Some Jupiter properties sit in mapped flood zones. A fully enclosed, air-conditioned room is usually treated differently from a screened lanai, and that can affect elevation requirements and permitting. We check your flood zone during the inspection so it does not surprise you later.
Slab and soil. Coastal lots are often sandy. If your patio slab has cracked, settled, or drains toward the house, we find that before we build on it. If your patio has pavers instead of a slab, they usually need to be evaluated or replaced before a roofed structure goes on top.
Who this is for
This is for Jupiter homeowners with a covered or open patio, a pool-side lanai, or a screen room that gets too hot, too wet, or too buggy to use. It also suits people who want an extra room such as an office, guest space, or Florida room and would rather build than move.
| Option | Roof | Air-conditioned | Cost |
|---|---|---|---|
| Aluminum lanai | Insulated aluminum | Usually not | About $52/sf on an existing slab |
| Conventional lanai | Insulated aluminum | Usually not | About $65/sf on an existing slab |
| Addition | Flat TPO or sloped concrete tile | Yes | About $250/sf |

What it costs
Typical projects run 12' x 20' to 20' x 20', and we build custom sizes. As illustrated examples only, not quotes:
| Size | Aluminum lanai | Conventional lanai | Addition |
|---|---|---|---|
| 12' x 20' (240 sf) | about $12,480 | about $15,600 | about $60,000 |
| 20' x 20' (400 sf) | about $20,800 | about $26,000 | about $100,000 |
For comparison, new construction runs about $350 per square foot, which is why adding on is usually cheaper than moving. Converting an existing patio into a room has no fixed price per square foot. It depends on slab versus pavers, whether the roof stays, impact glass, insulation, electric, AC, and any HOA delay. The patio to sunroom cost guide walks through each factor.
Process and permits
We inspect, design with you, handle any HOA notice, prepare plans and pull the permit, then build. The addition tie-in uses a ledger, or joists and trusses on the tie-beam, depending on your existing structure. We hold 5 state contractor licenses and EPS licenses. Structural, electrical, and HVAC work should always be done by licensed professionals.
Palm Beach County is outside the High-Velocity Hurricane Zone that covers Broward and Miami-Dade, but Jupiter is still a high-wind area and structures are designed for it. We confirm the exact requirements for your address. Read more in Sunroom Permits, HOA & HVHZ in South Florida.
