Old pools out, new pools dug
San Diego’s pool-era suburbs are fifty years old now, and every year more owners do the math on a backyard hole that costs real money to keep blue. Removal runs $6,000 to $12,000 for a partial fill and $9,000 to $20,000 for full removal that leaves buildable ground, both published on the cost guide. Going the other direction, we dig new pools for $2,500 to $8,000 and hand your pool builder a clean hole. Either way the ground ends honest: compacted, documented and ready for whatever comes next.
Why pools are coming out
The arithmetic changed. A pool that made a 1972 backyard the envy of the block now costs four figures a year in water, power and chemicals, and the same footprint has become the most valuable dirt on the lot: it is exactly where the ADU wants to go. Santee, Chula Vista’s west side and the El Cajon grid hold thousands of these decisions in waiting, and the removal-plus-pad package has become one of our signature projects. One machine mobilization covers the demolition, the engineered fill and the new pad, with compaction reports for the permit file.
The choice between partial and full removal is a future-use question, and we price both on the same visit so it gets decided with numbers. Partial fill is honest money for ground that will stay landscape. Full removal costs more and buys ground the city will let you build on, plus a cleaner disclosure story when the house eventually sells. What we will not do is bury a shell and call it buildable, because that shortcut always surfaces, usually under someone else’s foundation.
Pool questions, answered
What is the difference between partial and full pool removal?
Partial fill breaks the shell walls down, punches drainage holes in the floor and fills the void with compacted material, at $6,000 to $12,000. Full removal takes the entire shell out and rebuilds the hole with engineered compacted fill, at $9,000 to $20,000. Anything structural ever going over the footprint, an ADU included, requires the full version, and a partial-filled pool must be disclosed when you sell.
Can an ADU sit where our pool is now?
Yes, after full removal with compaction testing, and it is one of the most common projects we run. The pool comes out, the pad goes in and one mobilization covers both, which typically saves 15 to 25 percent against separate projects.
How long does a pool removal take?
Usually three to six working days on site: a day or two of demolition, the fill and compaction in lifts, then finish grading. Permits and utility disconnects add lead time up front, and we walk you through the county or city requirements for your address.
What does digging a new pool cost?
The excavation side runs $2,500 to $8,000 published, with access and ground setting the number. Tight gates mean smaller machines and more days; the granite that shows up in east county and Poway digs slower than the coastal soils. Your pool builder handles everything after the hole.
