There are several perks to building a deck around your inground or above-ground pool. Specifically, building a deck around a pool gives you space to lounge and sunbathe, easy access to monitor kids in the pool, extra room for entertaining and dining, an anti-slip surface for post-pool fun, and enhanced aesthetics.

An above-ground pool with a deck can increase your home's value by as much as 4% to 7%, but it depends on your local climate, potential buyers, and the size and condition of your pool. Some buyers see a pool as a liability instead of a luxury, especially if it's at the end of its life span. In general, it's best to add a pool and deck to your property if it will bring you enjoyment—not because it raises the value of your home.

Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.

Deck boards should be spaced no more than three-eighths of an inch apart. This is enough space to allow water and small debris to pass through without collecting on the surface, but not enough to create a tripping hazard. Certain materials, like pressure-treated wood, shrink over time, so they may need less space at installation.
