Patio Lanais & Sunrooms in Boynton Beach

In Boynton Beach, the first question is often not "what can I build?" but "what will my community approve?" Many neighborhoods here are HOA-managed, and approval time can decide your schedule. Preventive Maintenance builds insulated aluminum lanais, conventional lanais, and air-conditioned additions in Boynton Beach, and we prepare the plans, the permit, and the common HOA notices so the design matches what your community will accept.

Start with your HOA

Boynton Beach has many planned communities where exterior changes need approval before work starts. That affects a lanai or addition in three ways.

Appearance rules. Associations often care about roof color and style, screen or glass color, and how the new structure looks from the street. If your home has a tile roof, matching it on an addition is a common request.

Approval time. Review can take weeks, and an incomplete package can restart the clock. We prepare the common notices and drawings so the first submission is complete.

Order of operations. We usually design to the HOA's rules first, then permit, then build. Starting construction before approval is how projects get stopped.

If you have no HOA, the process is simpler and often faster. We will tell you which applies at inspection.

What we usually see on Boynton Beach homes

Many homes in planned communities have a rear patio or screened area on a concrete slab, often beside a pool. Common issues are slabs that slope toward the house, pavers laid over the patio, and existing screen enclosures with their own framing that has to be removed or worked around. Afternoon thunderstorms are routine through the wet season, so we pay close attention to where roof runoff goes, especially on tight lots.

Which option fits

Aluminum lanai: the fastest and lowest-cost way to get a shaded, bug-free space. Insulated aluminum roof, with screen or impact-glass walls.

Conventional lanai: wood-and-concrete construction for a closer match to the house.

Addition: a finished, air-conditioned room with a flat TPO or sloped concrete tile roof, tied in with a ledger, or with joists and trusses on the tie-beam.

See Lanai vs Sunroom: Which Should You Build? for a deeper comparison.

Cost

Our figures are about $52 per square foot for an aluminum lanai and about $65 per square foot for a conventional lanai on an existing concrete slab, about $250 per square foot for an addition, and about $350 per square foot for a new home. Typical sizes run 12' x 20' to 20' x 20', with custom sizes available.

As examples only: a 12' x 20' (240 sf) lanai is about $12,480 aluminum or $15,600 conventional, and the same footprint as an addition is about $60,000. At 20' x 20' (400 sf), that becomes about $20,800, $26,000, and $100,000. These are illustrations, not quotes.

Converting a patio into a room has no single price per square foot. HOA-required changes, such as matching roof materials, can also move the number. See the patio to sunroom cost guide.

Timeline, permits, and wind

Plan on 3–6 months on average. We hold 5 state contractor licenses and EPS licenses; structural, electrical, and HVAC work should be done by licensed professionals. Boynton Beach is in Palm Beach County, outside the High-Velocity Hurricane Zone that applies in Broward and Miami-Dade, but structures here are still designed for Florida wind and rain.
