Pool removal in Ontario needs a building permit from the city's Building Department, and Pool Removal California found 10 businesses offering in-ground pool removal there, 2 with an active state licence. Ontario requires the entire shell removed, so a partial fill-in is not an option without the Building Department's approval.

A pool removal in Ontario needs a licensed contractor or an owner-builder permit, because Industry Bulletin 24-07 keeps permitted work outside the $1,000 unlicensed-work exemption. The state classification guide explains the A, C-12, C-21 and C-53 classes most pool jobs use.
Ontario's Building Department requires a building permit to demolish or remove an in-ground pool or spa, applied for through the Citizen Portal, which the city has required since July 2023. A homeowner, a B general contractor, a C-53 pool contractor or a C-21 demolition contractor may apply. Information Bulletin 111, effective 16 October 2024, asks for a site plan drawn to scale showing the pool's location, size and depth and its clearances from property lines, nearby structures and retaining walls. The permit fee follows the valuation table on the city's building fee page, with plan check at 80% of the permit fee and a minimum permit fee of $47.50.
| Permit | Building permit |
|---|---|
| Issued by | Ontario Building Department |
| Published fee | Valuation-based; plan check 80% of permit fee, $47.50 minimum |
| City document | Information Bulletin 111 |
| Confidence | Medium |
The plan goes through a concurrent review by Building, Planning, Engineering, Landscape, OMUC Environmental and Public Works, and a tracking number is assigned once the plan check fee is paid. A resubmittal waits until every department has finished its review.
Before the final inspection, Information Bulletin 111 requires:
The bulletin names one inspection, the final, which can be booked at (909) 395-2362 or online.
Ontario allows one route: the whole shell leaves the site. The bulletin does not address leaving a shell in place, so a partial fill-in needs the Building Department's approval before anyone plans on it. The fill can be self-compacting material such as sand, or clean fill dirt compacted to at least 90% under the ASTM D1557 test, and the plan must show which.
The fill-in questions page sets the two methods side by side, with typical timelines of one to four days for a partial fill-in and three to seven for a full removal.
No contractor publishes Ontario prices. Because Ontario allows only full removal, the statewide full-removal range of about $8,000 to $30,000 is the one to plan around. The city's charges add the valuation-based permit and plan check, plus hauling: a 7-day bin at $95 and $369.29 for each inert or construction load on the July 2026 rate sheet.
The California pool removal cost guide covers what moves a quote, from side-yard access to fill dirt and the compaction report.
An approved Construction and Demolition Recycling Plan is a condition of any building or demolition permit in Ontario. The plan commits the job to divert at least 65% of its debris and to use the City of Ontario hauling service, unless the contractor self-hauls in company-owned trucks and containers and keeps weight receipts, and it ends with a final compliance report to Integrated Waste. The program carries no extra fee. On the city's July 2026 rate sheet, a 7-day temporary bin rents for $95, an inert or construction load adds $369.29 for disposal, and loads over 12 tons pay $115 a ton.
Pool water has to go somewhere before demolition starts. Ontario's pool maintenance guidance lists three routes: reuse the water on landscaping, send it to the sewer between midnight and 6 am, or dechlorinate it to zero residual and wait 24 hours before draining to the street or storm drain. Water treated with metal-based algaecides such as copper sulfate goes to the sewer, and the city's stormwater rules ban chlorinated water and algae solids from the storm drain.
Sellers in Ontario should keep the finaled permit, because the state's seller disclosure form asks about fill on the property and about unpermitted work.
Contractors listed for Ontario also work in neighbouring communities, including Rancho Cucamonga, Upland, Montclair, Chino, Fontana and Eastvale. Neighbouring cities set their own permit rules, so a job outside Ontario city limits follows that city's building department or, in unincorporated areas, the county.

Pool Removal California is an independent referral directory. The site is not a contractor and does not remove pools. Listed businesses may pay a referral fee when a homeowner is put in touch with them through the site, and that fee never changes the listing order: contractors with an active state licence appear first. The full referral disclosure and listing criteria explain how each business was checked.
