How Much Does a Lanai Enclosure Cost in Florida?
Lanai enclosure costs in Southwest Florida depend primarily on the type of enclosure, the square footage, and the roof design. Here’s a breakdown of what to expect in 2026:
| Enclosure Type | Cost per Sqft | 300 Sqft Estimate |
|---|---|---|
| Screen Only | $10 – $25 | $3,000 – $7,500 |
| Acrylic Windows | $15 – $40 | $4,500 – $12,000 |
| Glass Enclosure | $30 – $55 | $9,000 – $16,500 |
| Sunroom Conversion | $97 – $200 | $29,100 – $60,000 |
These ranges reflect current pricing across Lee and Collier counties. Roof style adds 0-25% to the base cost — flat/shed roofs are the most economical, while hip roofs require more engineering and materials. Add-ons like electrical work, upgraded screen doors, concrete pads, and permits can add $175 to $9,300 depending on what you need.
Factors That Affect Your Lanai Enclosure Cost
Size is the biggest cost driver. A small 150 sqft screen enclosure might cost $1,500–$3,750, while a large 500 sqft glass enclosure could run $15,000–$27,500 before add-ons. Materials matter too — hurricane-rated acrylic panels and insulated glass cost significantly more than standard aluminum screen framing.
Roof style impacts both material costs and engineering requirements. Gable and hip roofs add 15-25% over a flat roof because they require more aluminum framing, additional fasteners, and more complex engineering to meet Florida Building Code wind load requirements. Permits are required in Lee County (approximately $175) and your contractor must be licensed — Precision Aluminum holds Florida license #CBC1262890.
Site conditions also affect pricing. Uneven ground may require concrete work. Existing structures may need reinforcement. Electrical for fans, lighting, or outlets adds $500-$2,500 depending on the scope. The best way to get an accurate number is to call us at (239) 673-8357 for a free on-site estimate.

Does a lanai enclosure increase home value?
Yes, lanai enclosures typically provide a 50-75% return on investment in Southwest Florida. A screened lanai adds usable living space and is one of the most desirable features for Florida homebuyers. Glass enclosures and sunroom conversions can return even more because they add climate-controlled square footage.
What is the difference between a lanai and a sunroom?
A lanai is a covered outdoor space, typically screened, that is open to outside air. A sunroom is a fully enclosed, climate-controlled room with glass or insulated walls. Lanais cost $10-$55/sqft while sunroom conversions cost $97-$200/sqft. Many Southwest Florida homeowners start with a screened lanai and later convert to a sunroom.
