What a Filled-In Pool Does to Your Property Value and Your ADU Plans
Filling a pool in is the cheaper option. It can also attach a recorded restriction to part of your lot that the next owner inherits.

Most of the pools we are asked to remove in Orange County went in between the 1960s and the 1980s. By now the replaster, the tile, the coping and the equipment have all come due at once, and the owner decides the yard is worth more without a pool in it.
The cost side of that decision is covered in our guide to pool removal cost in Orange County. This article is about something homeowners are told far less often: the method you choose changes what the land underneath is allowed to become, and one of the two options can put a permanent restriction on part of your lot.
The two methods, briefly
In a partial backfill, sometimes called a fill-in or abandonment, the top of the pool wall is broken off and the shell stays in the ground. Holes are cut through the floor so groundwater and rain drain away instead of collecting in a concrete bathtub under your lawn. California building departments are usually specific about this: a typical requirement is at least three holes of at least 24 inches in diameter, no more than eight feet apart. The broken concrete goes in the hole, soil or gravel goes on top, and the surface is graded.
In a full removal, the entire shell comes out: walls, floor, rebar, plumbing lines, skimmers and the equipment pad. Everything is hauled off rather than buried, and the hole is backfilled in compacted lifts with approved material.
The part that decides everything: compaction testing
Engineered backfill is normally compacted to 90 percent relative compaction under ASTM D 1557, verified by an accredited soils agency, with a final compaction report from a licensed civil or geotechnical engineer submitted to the building department. That report is what turns a hole in the ground back into land you can build on.
When a pool is filled without that engineered, tested compaction, the result is classified as uncertified or non-engineered fill. Building departments generally allow it, but they allow it for landscaping only, and they frequently require a covenant to be recorded against the property restricting that area from carrying any building or structural support.
Read that again, because it is the whole decision: the cheaper method can attach a permanent, recorded restriction to a portion of your lot. It does not expire when you sell. The next owner inherits it.
What that does to your property value
A filled pool is a material fact in a California sale, so it gets disclosed either way. The question is what you are disclosing. Engineered fill with a compaction report on file is a clean document handed to the buyer. Uncertified fill with a recorded covenant is a restriction the buyer's agent, appraiser and lender will all read.
The practical effect is on what the yard can become. If that area can never hold a structure, it cannot hold an addition, a garage, a casita or an ADU. In California, where an ADU is often the single highest-value thing an owner can add to a suburban lot, giving up the buildable part of the back yard to save money on a demolition is a trade worth making deliberately rather than by accident.
When partial backfill is the right call
It is the right call more often than you might expect. If the pool sits in a side yard or a corner you will only ever landscape, if you are staying in the house, if the budget is tight, or if access is so tight that hauling out the full shell means hand work and many truck loads, partial backfill is sensible and we will tell you so.
When full removal is worth the difference
Choose full removal if the pool occupies the part of the lot where an ADU, addition or garage would logically go; if you are preparing the property for sale and want the cleanest possible disclosure; if the pool is large relative to the yard; or if you simply do not want to hand the next owner a deed restriction.
Permits and utilities in Orange County
Either method is permitted work. Expect a demolition permit, and a grading permit based on the volume of fill. Gas to the heater and power to the pump both have to be disconnected properly, and the work is inspected. Requirements and the exact wording of any covenant vary between Orange County cities, so the specifics for your address come from your own building department. We handle the permit coordination and the inspections as part of the job.
Getting a straight answer for your yard
The right method depends on where the pool sits, what you plan to do with the property, and how long you intend to stay. We will walk the yard, tell you which method fits, and price both so you can see the real gap rather than guessing at it.
