The short answer: in Collier County, a straightforward lanai rescreen runs roughly $700 to $5,000, a new screen enclosure typically lands between $7,000 and $19,000, and converting a lanai into true air-conditioned living space is a different project entirely, usually $22,000 to $75,000 and up. The spread is wide because “lanai renovation” covers everything from new mesh panels to a permitted structural addition. Here is how the numbers break down, what Collier County requires, and where budgets actually go in Southwest Florida.
Key takeaways
- National cost data from HomeAdvisor puts a new pool or lanai enclosure at $12,168 on average, with most projects between $7,051 and $18,831. Screen enclosures run $8 to $15 per square foot.
- Florida contractor pricing is consistent with that: one high-volume screen builder publishes $2,000 to $6,000 for a basic lanai screen, $6,000 to $12,000 for larger custom patios, and $10,000 to $35,000 for standard pool cages.
- Rescreening an existing structure is the budget play, at $700 to $5,000 depending on damage and mesh choice.
- Full conversion to a sunroom or conditioned room averages $47,000 nationally, at $150 to $300 per square foot, with four-season builds reaching $120,000.
- Collier County treats screen enclosures as permitted aluminum structures (permit type PRAS), and Florida’s hurricane code requires engineered wind-load design, so unpermitted work is a real liability here.
- Converting a lanai into living area can trigger a county impact fee review if the home’s total living square footage crosses a fee tier.
What lanai work actually costs
Lanai budgets split into three tiers: repair what exists, rebuild or add an enclosure, or convert the space into conditioned living area. National figures from HomeAdvisor’s cost guides and published 2025 pricing from Lafferty Aluminum and Screening, a Florida enclosure builder with more than 6,000 installations, frame the ranges below. Naples pricing tends toward the upper half of state ranges, reflecting Collier County labor costs and the engineering that coastal wind zones demand.
| Project | Typical cost | Basis |
|---|---|---|
| Rescreen or repair existing enclosure | $700 to $5,000 | HomeAdvisor national data |
| Basic lanai or patio screen enclosure | $2,000 to $6,000 | Florida contractor published pricing |
| Larger or custom patio enclosure | $6,000 to $12,000 | Florida contractor published pricing |
| New pool or lanai enclosure, most projects | $7,051 to $18,831 (average $12,168) | HomeAdvisor national data |
| Standard pool screen enclosure | $10,000 to $35,000 | Florida contractor published pricing |
| Large or two-story pool cage | $30,000 to $60,000+ | Florida contractor published pricing |
| Sunroom or conditioned conversion | $22,000 to $75,000 (average $47,000) | HomeAdvisor national data |
Tier one: rescreen and refresh
If the aluminum frame is sound, replacing tired or storm-damaged screen panels is the highest-return move on the list. HomeAdvisor puts rescreening and enclosure repair at $700 to $5,000, with the final number driven by how many panels need work and which mesh you choose. Standard 18-by-14 fiberglass mesh is the economical option. Upgrades change the experience of the room: 20-by-20 no-see-um mesh keeps out the tiny biting insects that regular screen ignores, and privacy screen (often sold as Florida Glass, a vinyl-laminated mesh) blocks sightlines and windblown debris on lower panels. While the crew is there, budget for new fasteners and door hardware. Corroded screws and sagging doors are usually what makes a lanai feel worn, not the screen itself.
Tier two: a new screen enclosure
A new enclosure is where Southwest Florida realities show up in the quote. Every legitimate bid in Collier County includes engineered drawings and wind-load calculations, because Florida Building Code treats a screen enclosure as a structure that has to survive hurricane-force wind, not a glorified tent. Roof style matters to price: flat roofs cost least, while mansard and gable profiles add material and labor. Height matters too, since two-story cages covering a pool and second-floor balcony need heavier framing.
Expect $8 to $15 per square foot for screen enclosures per HomeAdvisor, which matches the $10,000 to $35,000 window Florida builders publish for standard pool cages. Timelines run longer than most owners expect: four to twelve weeks from contract to completion is typical once engineering and permitting are counted. If your lanai project is part of a larger condo update, read our guide to condo remodeling in Naples first, because association approval adds its own clock.
Tier three: converting the lanai to living space
Enclosing a lanai under air is the project that transforms how a Naples home lives, and it is priced accordingly. You are adding walls or glazing, insulation, electrical, and conditioned air to a space that was engineered as outdoor area. HomeAdvisor’s sunroom data puts the average at $47,000, with most projects between $22,000 and $75,000 and a per-square-foot range of $150 to $300. A three-season room with windows but limited insulation runs $10,000 to $40,000. A true four-season room, insulated and tied into HVAC, runs $25,000 to $120,000. Labor alone typically accounts for 40 to 60 percent of the total.
Two Collier-specific cautions. First, conversions that add living area can trigger an impact fee review; the county assesses fees when the home’s total living square footage crosses into a higher tier, and its Impact Fee office publishes a calculator for exactly this scenario. Second, floodplain rules matter near the coast. Enclosing space below required flood elevations brings FEMA’s substantial improvement math into play, which the county’s Floodplain Management section administers. Neither is a dealbreaker. Both are reasons the permit conversation happens before the contractor conversation. The same sequencing logic applies to interior projects, as we covered in our Naples kitchen remodeling cost guide.
Permits in Collier County, in plain terms
Collier County publishes application requirements by permit type, and screen enclosures fall under the aluminum structures category, permit type PRAS. Applications run through the county’s online permitting portal, and the county notes that a screen enclosure or pool added after a primary permit requires its own separate permit. Plan on providing a site plan, engineered drawings, and product approval documentation for the components used. Permit fees themselves are modest relative to the project: HomeAdvisor cites $30 to $325 for enclosure permits nationally and $250 to $1,500 for room additions, and reputable Florida enclosure contractors build permitting and engineering into their quotes and handle the filings.
Homes inside Naples city limits should confirm whether their permit runs through the city’s building department rather than the county. And regardless of jurisdiction, hire licensed contractors and verify the license. Florida law makes unlicensed contracting a crime for the contractor, but the practical damage lands on the homeowner: no enforceable warranty, insurance complications, and problems at resale when unpermitted work surfaces in an inspection.
Where the money goes in Southwest Florida
Four factors move a Collier County lanai quote more than anything else. Size and height come first, since material and labor scale together. Engineering comes second: coastal wind zones require structural calculations that inland projects skip. Foundations come third, because a new or extended concrete slab or paver deck adds real cost. Mesh and finish choices come last but compound across hundreds of square feet. When comparing bids, make sure each one states the mesh type, the aluminum gauge, and whether engineering and permit costs are included. The cheapest number on the table is often the one missing those three lines.
Frequently asked questions
Do I need a permit to rescreen my lanai in Collier County?
Replacing screen mesh in an existing, permitted enclosure is generally treated as maintenance, but structural work, panel framing changes, or a new enclosure requires a permit under the county’s aluminum structures category. Collier County publishes a list of work exempt from permits, and checking it, or calling the Building Plan Review and Inspection Division, takes minutes. When a contractor offers to skip the permit on structural work, treat that as a red flag, not a discount.
How long does a lanai enclosure project take in Naples?
Florida enclosure builders quote four to twelve weeks from consultation to completion, and the range is mostly permitting and engineering rather than construction. The build itself often takes days once materials arrive. Full conversions to conditioned space run longer, typically two to four weeks of construction after permits are issued, plus HVAC and electrical inspections.
Does enclosing a lanai add value to a Naples home?
Screened outdoor space is close to a baseline expectation in Southwest Florida, so a clean, permitted enclosure protects value more than it multiplies it. Conditioned conversions add usable square footage, and HomeAdvisor estimates sunroom additions return roughly 49 percent of their cost at resale. The stronger case is livability: a converted lanai is the room that gets used twelve months a year.
