How Much Does It Cost to Fill In a Pool in the Bay Area?

If you are deciding what to do with an old swimming pool, you may have found yourself searching for the cost to "fill in" a pool rather than "remove" it. Those two phrases get used almost interchangeably — and for good reason, because filling in the hole is how most removal projects actually finish. Whether the whole shell comes out or part of it stays in place, the excavation gets filled and graded at the end.

So the cost of filling in a pool is, in practice, the cost of a pool removal project. Here is what that runs in the Bay Area, and what moves the number up or down.

The Short Answer

Most in-ground pools in the Bay Area cost somewhere between $15,000 and $40,000 to remove and fill, with many projects landing in the $18,000 to $30,000 range. Above-ground pools are usually the least expensive to take out and fill.

Two homes on the same street can still see very different numbers, though, because the price depends on your pool and your plans — not on the region as a whole.

"Filling In" a Pool Is Really Pool Removal

When someone says they want to fill in their pool, what they usually mean is that they want the pool gone — drained, broken up (or partly left in place), and the excavation turned back into usable ground. That is exactly what pool removal and pool demolition do. Demolition takes the structure apart; the backfill turns the empty hole back into level yard.

The distinction that actually matters is not the wording — it is the two choices that shape the whole project: how much of the pool comes out, and how the fill is placed. Those two decisions drive almost the entire cost. For the full comparison, see our guide to partial vs. full vs. engineered pool removal.

Part 1: How Much of the Pool Comes Out

Partial removal — leave part of the shell, fill around it

With partial removal, the upper portion of the pool is broken out, drainage holes are drilled into what remains, and the area is backfilled. Because less material has to be demolished and hauled away, this is typically the most affordable way to fill in a pool. It is a good fit when the space is only ever going to be landscaping — a lawn, a garden, a play area.

Full removal — take everything out, then fill

Full removal takes out the entire shell, concrete, rebar, and plumbing, hauls it off-site, and then backfills the empty excavation. It costs more than partial removal because there is far more material to break up and dispose of, but it leaves no buried structure behind. Many homeowners choose it simply because they want the pool truly gone.

Part 2: How the Fill Gets Placed

This is the part most homeowners do not hear about until they are comparing quotes — and it can matter more than the first question. There are two ways to fill a pool excavation:

• Non-engineered fill — soil goes in with little or no compaction. It is faster and cheaper upfront, but the ground settles on its own over time, sometimes for months, leaving dips and low spots. During that window, the area is not really usable.
• Engineered fill — soil is placed in compacted layers, tested, and documented. It costs more, but it stabilizes the ground quickly and is what you need if the area will ever support a structure.

We break down the tradeoff — and why "cheaper now" can mean "unusable for months" — in why non-engineered removal can leave your yard unusable. Some Bay Area jurisdictions also require engineered fill regardless of the removal method, so it is worth confirming for your city.

Can You Build Where the Pool Was Filled In?

Only if the fill was placed as part of an engineered full removal, with compaction testing and documentation. Building departments will not approve a permit for an ADU, addition, or garage over a former pool site without that documentation — even if the pool is completely gone and the yard looks perfectly level.

That is why, if there is any chance you will build something there later, engineered removal from the start is almost always the smarter move. Going back later to redo a standard fill so it meets construction standards is far more disruptive and expensive than doing it correctly the first time. See our guide to engineered pool removal for ADU construction.

What Else Drives the Cost

• Pool size and depth. More concrete, rebar, and debris to remove means more cost. Deeper pools also need more fill material to bring the ground back to grade.
• Equipment access. If machinery can reach the pool easily through a driveway or wide side yard, the project moves faster. Narrow gates, retaining walls, and sloped terrain can require smaller equipment and more labor.
• Removal method. Partial removal sits at the lower end; full removal costs more; engineered full removal adds the most because of the testing and documentation.
• Permits. Permit fees are set by your city or county and are separate from the contractor's quote. Learn more in do you need a permit to remove a pool in the Bay Area.
• Final finish. Rough grading is included in a removal; sod, garden beds, or a new patio are separate. Leaving the yard partially finished is one of the most common regrets after a budget-driven removal.

Why Homeowners Fill In Pools in the Bay Area

Across the region, pools built during the mid-century boom are now decades old, and many have reached the point where upkeep costs more than the pool is worth. Rising water and electricity rates, drought-era landscaping, and California's active ADU market all push homeowners toward removal. For many, a pool that once hosted summers now sits unused while still demanding chemicals, heating, cleaning, and repairs every month.
