Adding a sunroom to your home is a great way to enjoy warm weather and the natural beauty of the outdoors with all of the comforts of staying inside. But is a sunroom a good investment? Depending on the type of sunroom and how it’s constructed, this add-on can offer a 20% to 50% ROI. Learn more about what factors affect the added value of a sunroom so you can decide if it’s the right project for your home.

Factors That Influence Sunroom Value

Sunrooms vary widely in size, use, and construction—all of which can affect their value. Even where your home is located can influence how much of an ROI you can expect. We delve deeper into some factors affecting a sunroom’s value.

Location

While a sunroom is an appealing addition no matter where you live, they may be more in demand in warmer climates. In some hotter areas, buyers may prefer a home with a sunroom, so not having one may cause prospective buyers to skip your listing. In colder areas, sunrooms can’t be used year-round, so while it may be a nice feature, it’s not as much of a must-have as in hotter climates, and the resale value will reflect that.

Pro Tip

Also, a very important factor is placement. If your sunroom faces south it’ll get more sun but might need more cooling. If it faces west it can get hot in summer afternoons, despite AC.

Size

A sunroom’s size will be a major contributing factor in determining its value. The larger the sunroom, the more value it’ll add to your home. Below are some common sunroom sizes and the average resale value they add.

Size (Sq. Ft.)Average Resale Value
100$3,000–$15,000
150$4,500–$22,500
200$6,000–$30,000
300$9,000–$45,000
400$12,000–$60,000

The type of sunroom you build will make a difference in its value. A screened-in sunroom like an Arizona room will be worth more than a screen porch, but less than a three- or four-season room. A three-season room, which normally lacks insulation and a heating system, will bring a more moderate ROI than a four-season room, which can be fully enclosed and outfitted with heating and cooling systems.

Construction

Sunrooms that are fully integrated into the design of the house, using the same materials, will bring the highest ROI. Sunroom additions that are a different style than the rest of the house or appear to be a lesser build quality won’t make as much of an impact on home value. The sunroom’s foundation, flooring and roofing quality, and overall structural integrity can make a big difference when determining how much value it adds.

DIY vs. Hiring a Pro

Adding a sunroom to your home is serious structural work, so you’ll want to hire a local sunroom contractor to ensure it’s built to code, that you have any permits you need to build a sunroom, and that the design and quality are what you expect. Look for a contractor who builds sunrooms in the style you’re interested in—there are many different types of sunrooms to choose from.

If you’re looking to keep costs down when adding a sunroom, you may be able to DIY some of the finish work like adding trim, installing flooring, hanging drywall, or painting. It’s a good idea—and sometimes legally required—to leave the major construction to experienced, licensed professionals.

How to Estimate the Added Value of a Sunroom

To estimate the added value of a sunroom, consider the following factors:

  • Look at market demand. If a majority of homes in your area have sunrooms, it may be a feature buyers consider non-negotiable.

  • Explore tax and insurance implications. Adding a sunroom will not only affect your home’s value, but also the amount of tax you pay and your insurance premiums. Find out in advance how a sunroom will affect your recurring payments.

  • Calculate costs versus potential return: The total cost to build your sunroom includes labor, materials, permits, land prep, and added features. Compare the building costs to the potential increase in value to see how it stacks up.

  • Determine the effect on your property. If you have a small yard, adding a sunroom may reduce your usable yard space and make your property less appealing to buyers. Determine the ideal size to maintain a balance between indoor and outdoor use of your property. 

Cost to Install a Sunroom

A sunroom addition costs an average of $150 to $300 per square foot. Costs will vary based on size, materials, necessary site prep, labor, utilities, and more. Sunrooms like screen rooms that have a more basic structure and fewer features will cost less than four-season rooms and sunrooms with premium options, HVAC extensions, and upgraded features. 

Is a Sunroom Worth It?

Whether a sunroom is worth it or not depends on the homeowner, the local real estate market, the room’s construction and function, and other factors. Not sure if a sunroom is the right choice for your home? Weigh the pros and cons to help decide.

Adds lots of natural lightHigh up-front cost

Frequently Asked Questions

A sunroom will add more value to your home than a deck, but with a much higher up-front cost. Depending on its construction and function, a sunroom may be counted as additional living space, while a deck is strictly an outdoor feature. Both will increase your home’s value, but the sunroom will have a much bigger effect.

A well-constructed and well-maintained sunroom can last as long as the rest of your house. If you build the sunroom to the same standards using the same quality materials as the house and perform regular maintenance to ensure the room stays in top condition, it can bring you decades of enjoyment.
