A partial removal means draining out the water and filling the structure left behind. And while a total pool removal can cost between $15,000 and $20,000 versus the $5,000 to $12,000 figure for a partial removal, it may pay off in the long run. While specific laws and regulations can vary depending on where you live — you can check local property disclosure laws, or consult with a real estate agent — generally you're not allowed to build over a filled-in pool. That means you can't use that space to add square footage to the home or house an additional structure. Even if you weren't planning a backyard expansion, if could become an issue should you decide to put your house on the market.
