If a sunroom counts as square footage is largely based on the type of sunroom, how it’s built and local building codes. Here’s a breakdown to help you make sense of it:
Four-Season Sunrooms: When a sunroom is fully insulated, heated and cooled and constructed to the same standards as the rest of your home, it is typically considered part of the total squared footage in your home. These are designed for year-round use and often are included in the total living area.
Three-season sunrooms: These types of sunrooms are not well insulated and are designed for use only in warmer months. Since they aren’t totally conditioned spaces (they don’t have heating and/or cooling), they usually don’t count in the total square footage. But if they’re completed and finished and usable, some appraisers or local regulations allow for them to be counted.
Unfinished Sunrooms: A sunroom is generally not considered in the square footage if it is unfinished or lacks proper insulation.
For the best answer as it applies to your case, it’s recommended to reach out to a neighboring appraiser or structure authorized official. Our sunrooms by Archsky are designed with compliance to all regulations in mind, so you can enjoy a functional and aesthetically pleasing addition to your home!
