Rules and Regulations
Indiana’s Private Swimming Pool Laws

Although owning a pool is fun, it also entails a good deal of responsibility. Indiana requires residential swimming pool owners to adhere to state and local laws. Gaining a better understanding of these pool laws can help ensure your pool is compliant and meets all state and regional codes.

Because state and local laws can change over time, it’s important to do your research beforehand to be sure your pool is up-to-code. Working with a professional builder can help you more easily navigate the most recent codes, as well as help you secure the proper permits to build your new pool.

Here are some of the most common questions about pool regulations in Indiana.

Do I need a permit to build a pool in Indiana?

If you plan to build a pool in Indiana, you will require a permit issued by the state. Indiana state permits require that a pool must be built at least 10 feet away from any structure on the property and be situated in either a backyard or side yard. Your local municipality may have additional permitting requirements. For instance, Indianapolis requires a Residential Development Permit application, which must be accompanied by site plan drawings, as well as a structural, improvement and drainage permit.

As another example, the town of Hebron, IN requires pool permit applications to be accompanied by a site plan, as well as a picture or brochure of the pool’s style. An additional permit is required for pool fencing. Hebron’s legal guidelines also require prospective pool owners to work with installers, contractors or subcontractors who have registered with the town for that year.

Because laws can change over time, it’s important to investigate what permits you are responsible for obtaining so that your pool is compliant. Working with a licensed professional builder can help you better understand the most current updates to any state and local pool laws in Indiana.

How much does a pool permit cost in Indiana?

The cost of a pool permit in Indiana varies depending upon where you live and specific permits required. The state of Indiana has a schedule of fees that apply to those who plan to install a swimming pool. Categorical processing fees for swimming pools are $0.02 times the gross cubic footage of the pool.

Other local governments throughout the state have their own permit fees. For instance, Hebron, IN charges $150 for an in-ground pool permit and $50 for a pool fence permit under the town’s Improvement Location Permit plan.

Because permitting fees and requirements may change over time, check with your local building office to understand which fees and applications you are responsible for, depending on where you live.

How tall does a pool fence have to be in Indiana?

Indiana requires that all residential pools must be surrounded by a fence or barrier at least 4 feet high. Your fence must also have self-closing, self-latching gates and surround the pool on all sides. Please keep in mind that this is the minimum requirement for fencing and that your city, town, or municipality may have additional height requirements to ensure your pool fencing is compliant.

Do you have to have a fence around a pool in Indiana?

The state of Indiana requires that all residential pools under 48” high must be surrounded by a self-latching, self-closing fence at least 4 feet high. This fence must encircle the pool on all sides. Residential pool owners who have an inground pool may be exempt from this fencing requirement if they have an approved 400-lb autocover on their pool in lieu of fencing.

Please note that this is the minimum requirement across the state and that your city or town may have additional rules in place. Be sure to check with your local building office to be sure you are operating from the most recent guidelines.

If my backyard is already fenced, do I need a fence around my pool in Indiana?

Even if you already have a fence prior to building a pool, it must be compliant with Indiana state and local requirements for pool fencing. This may require you to upgrade your existing fence. Overall, the state requires that all residential pools under 48” high must be surrounded by a fence at least 4 feet high on all sides. However, residential pool owners may be able to bypass this requirement if they have an approved 400-lb autocover.

Because laws can change over time and local laws in your municipality may be more prohibitive than those overarching the state, Indiana residents should check with their local building office to be sure their pool and fence meet all legal requirements. Working with a licensed professional builder can help you better understand these laws and your responsibilities as a pool owner.

Seasonality
Owning a fiberglass pool in Indiana means enjoying a low-maintenance, durable backyard retreat—but seasonal care still helps you get the most out of your investment. Here’s what to keep in mind throughout the year:

Spring: Many Indiana homeowners open their fiberglass pools in April, though a mild winter may tempt some to start as early as mid-March. Spring brings high pollen counts—especially between April and June—along with plenty of blowing leaves and blossoms. Pollen grains often appear as tiny green or yellow specks floating on the surface. Skimming regularly and keeping filter baskets clear will prevent clogs and maintain optimal circulation.

Fall: Heated fiberglass pools often extend the swimming season into early fall. However, Indiana’s beautiful, tree-filled landscapes also mean plenty of leaves and debris. An automatic pool cover can help keep your pool clean, reduce maintenance time, and protect your water chemistry—allowing you to enjoy crisp autumn swims before closing for the season.

Winter: Before freezing temperatures set in, close your fiberglass pool properly by removing water from plumbing lines, protecting skimmers, and ensuring all equipment is winterized. While many pool owners handle this themselves, professional services are available for added peace of mind. A high-quality winter pool cover—different from an automatic cover—is designed to withstand heavy snow loads and protect your fiberglass shell during Indiana’s harshest weather.

Planning a Backyard Fiberglass Pool in Indiana? Here’s What to Know:

• Average number of sunny days annually: Around 186, giving you plenty of warm-weather opportunities to enjoy your pool.

• Average summer temperature (June–August): Typically ranges from 83°F to 87°F, with moderate to high humidity perfect for cooling off in the water.

• Average winter temperature (December–February): Usually between 17°F and 35°F, meaning most pools are closed in colder months unless equipped with heating for year-round use.

• Average pool temperature: Stays between 78°F–85°F in summer, and can be maintained at 70°F–75°F in spring and fall with a pool heater, extending your swim season.

• Average annual precipitation: About 42 inches, which supports healthy landscaping but can increase the need for debris removal and water chemistry balancing.
