The 30-Second Verdict
A Florida room (glass-enclosed sunroom) costs $20,000–$60,000 but adds year-round livable space usable even in summer heat and adds more to appraisal value. A screened porch costs $5,000–$20,000, requires less permitting, and is beloved by Florida buyers for outdoor living without insects. Both add significant value; budget determines the winner.

Frequently Asked Questions
Do Florida rooms or screened porches add more value to a home?
Florida rooms (conditioned, glass-enclosed) add more to appraised value because they count as heated/cooled square footage. However, screened porches have very broad buyer appeal in Florida and often return 60–80% of construction cost at resale. The right choice depends on budget and how you use the space.
What's the difference between a lanai and a screened porch in Florida?
In Florida, 'lanai' and 'screened porch' are often used interchangeably. Technically, a lanai is a Hawaiian-influenced covered outdoor room — typically at pool level with a screen enclosure. A screened porch usually refers to an elevated deck or patio area with screen walls. Both serve the same core function: pest-free outdoor living.
Do I need a permit for a screened porch in Florida?
Yes — any permanent structure addition in Florida requires a building permit. A screened porch or pool enclosure typically requires a simpler permit than a fully enclosed addition. Always hire a licensed contractor who pulls permits; unpermitted additions can cause serious issues at sale.
