Adding a sunroom addition to your home is a great way to enjoy lots of natural light and bask in the benefits of the outdoors without any of the nuisances that come with it, like bugs and yard debris. Before beginning construction on your sunroom project, it’s important to know whether or not you need to obtain a permit and what can happen if you don’t.  

What Is a Sunroom?

A sunroom is a room with abundant natural light provided by walls made of glass windows, mesh screens, or a combination of the two. Sunrooms may have low partial walls in addition to windows or mesh, and are often attached to the side or rear exterior of the house and accessible from inside. There’s a wide variety of types of sunrooms, ranging from screened-in Florida rooms to all-glass solariums.

You will need to obtain a building permit before building a sunroom. A sunroom is a major construction project involving a foundation, roof, windows, and many other components that are regulated by building codes. A permit ensures all work is performed legally and according to local regulations, and that your local building authority has signed off on the project.

Price Notice

Permits can actually be quite expensive. Talk to your contractors before starting your project to understand how much the required permits will cost you.

Hiring a contractor who builds sunrooms and is familiar with the local permit process and regulations will ensure your project proceeds smoothly, and you won’t run into any of the consequences for not obtaining the correct permits.

Risks of Not Getting a Permit

The cost of a sunroom can be a major investment, but failing to obtain a permit can cost you much more in fees or fines. In some cases, you may even be required to tear down the unpermitted work. A sunroom constructed without the proper permits can also lead to problems with your homeowners insurance coverage and can make it difficult when it comes time to sell your home.

Obtaining a permit may be inconvenient, but it’s a critical step for any construction project. As the homeowner, you’re responsible for confirming that the right permits have been pulled, but check with your local building authority to confirm whether you or your local sunroom contractor should be the one to apply.  

How to Obtain a Permit for a Sunroom

The permit application process varies by location, so before getting started, confirm what information and documentation you’ll need to provide. In most cases, you’ll need to provide a permit application fee and detailed design plans drawn up by a licensed professional that include sunroom size and other construction specifics. The building authority will review your plans and either approve them or let you know what alterations need to be made.

During and after construction, local officials will inspect your project to ensure it meets all codes and regulations. Once the project is complete, they’ll sign off on an approval, indicating that your sunroom addition is legal, compliant, and structurally sound.

Frequently Asked Questions

Sunrooms may count toward your home’s total square footage if certain conditions are met, depending on local regulations. You may be able to include a sunroom in your square footage if the room is fully enclosed, has a heating and cooling system, and meets the same construction standards as the rest of your home.

Sunrooms can add value to your home, offering a return on investment (ROI) of 20% for a screen room to 50% for a three- or four-season room. Sunrooms may be a more worthwhile investment in warmer climates, where many potential buyers are looking for this feature. In colder areas, a sunroom may be seen as more of a “nice-to-have” rather than a “must-have” and may not be as sought after.
