The Four Types of Lanai Enclosure
Before pricing, it's important to understand the spectrum of lanai enclosure options, because costs vary dramatically by type.
Type 1 — Screened only: Aluminum frame with screen panels, open to the sky except where it attaches to the home's roof. Lowest cost, maximum airflow and light.
Type 2 — Covered screen room: Same screen walls but with a solid or screen roof panel extending from the home. Provides rain protection directly under the covered area.
Type 3 — Full solid roof: Aluminum or insulated panel roof covers the entire lanai. Year-round rain protection, can support ceiling fans and lighting. Most popular option for entertaining.
Type 4 — Florida room (enclosed): Solid walls with impact glass or acrylic windows. Essentially an addition — fully climate-controlled or ventilated year-round room.

Permit Requirements
All lanai enclosures in Florida require a building permit. Requirements vary by county but generally include engineering drawings for wind load calculations, inspections at framing and completion stages, and compliance with Florida Building Code Section 1609 (wind loads). Budget $200–$600 for permit fees depending on project value and county.
