Does a 3 season room count towards square footage?

Whether a three-season room counts toward a homes square footage depends on how it is built, not just what it is called. In Hernando County and throughout Florida, conditioned (heated and cooled) space with proper insulation, a finished ceiling, and electrical that meets code is typically included in the gross living area (GLA) used for appraisals and MLS listing purposes. An unheated room with screen or glass panels is generally not included in the GLA, regardless of what the seller calls it. Three-season rooms by definition are not year-round climate-controlled spaces, which means most appraisers and MLS systems would not count them toward square footage. However, a fully enclosed addition with HVAC connected to the homes main system, proper permits, and a finished interior may qualify. The only reliable answer for a specific property is to review the permit history, confirm what the county records show as the living area square footage, and consult a licensed Florida appraiser if the classification is material to your pricing or financing decision. Buyers should verify square footage claims independently rather than relying on MLS data alone. Kevin Neely & Kaitlynd Robbins | K2 Sells, Keller Williams Elite Partners

Usually no—it typically isn’t counted unless it’s fully enclosed, permitted, heated/cooled, and finished to the same standard as the rest of the home.

Heated/cooled space is usually included in your total sq. footage. Although a screened porch is added "living space" it is not calculated as such. An increase in your sq. footage could result in increased property taxes for you (or for the new owner if your property is being sold).

In most cases, no. For a space to count as square footage, it typically has to be heated and cooled with a permanent system that’s connected to the rest of the home. Most 3 season rooms don’t meet that standard, so they’re not included in the official square footage. That said, they still absolutely add value. In the Knoxville market, buyers often love those spaces, especially when they’re well done and usable most of the year. I make sure they’re highlighted properly in the marketing so you still get credit for them, even if they aren’t counted in the total square footage. The key is making sure it’s positioned correctly so it helps your value without creating issues during appraisal.
