In most states, it is a legal requirement to have a fence around your pool to protect both swimmers and pool owners. These laws can vary by state, city, and county, so you must research the specific regulations in your area before installation. The rules may also differ for inground versus above-ground pools, with inground pools typically requiring a full fence. Additionally, most homeowners' insurance providers will require a fence around a residential pool before providing coverage. As a general rule, it's always best to have a fence for everyone's safety.

The generator in your saltwater pool conversion kit transforms sodium chloride—the same salt as table salt—into chlorine. A process called electrolysis sends electricity through the water to interact with the chlorine ion. This ultimately creates the chlorine that keeps your pool safe and clean. The cell in your saltwater chlorine generator is the part that converts the salt into chlorine.

Your aboveground pool might technically be able to stand without water, but you shouldn't consider it stable. Aboveground pools need the weight of water to provide adequate stability and prevent the walls from collapsing in. Be sure to fill your pool with water as soon as possible after installation.

Yes, you will need building permits for an inground pool, and your pool installation company should pull them for you. The permit filing fee will usually sit between $400 and $1,800, and it should appear on your contract or invoice. You may want to confirm with your contractor that they will pull all necessary permits. You might also need a permit for a new fence, as many municipalities have special fencing requirements for properties with pools. A fence permit costs between $50 and $500. This expense may not be included in your pool installation estimate.
