Hiring a pool contractor
At a glance: In California a pool job of $1,000 or more needs a contractor licensed for the work, normally a C-53 Swimming Pool contractor. The contract must include a scale drawing and equipment specifications, and the down payment is capped at 10 percent or $1,000, whichever is less[1][2][4].
Who can legally build a pool in California?
Any contracting job of $1,000 or more, including pool construction or repair, must be done by a contractor with a current, valid license in the classification for the work[1]. Pool builders are licensed as C-53 Swimming Pool contractors; a general building contractor may contract for pool work only if it holds the C-53 classification, hires a licensed pool contractor, or oversees the pool as part of a larger project. Landscape contractors may contract for a pool as part of a larger landscaping project. Plumbers, landscapers and other specialists cannot be responsible for the whole pool project.
What about salespeople?
Licensed contractors may employ registered home improvement salespeople (HIS). A salesperson who sells or negotiates a pool contract away from the contractor’s place of business, for example in your home, must be registered with CSLB and should be ready to show the registration. CSLB advises checking that the pool company you are dealing with is listed on the salesperson’s registration[1].
How does CSLB suggest choosing a contractor?
CSLB recommends verifying the license or HIS registration online, asking to see identification, getting referrals from friends, family or trade associations such as a builders’ exchange or pool and spa association, getting at least one current and one completed reference from the contractor, and getting at least three bids[1].
What must a pool contract include?
A written contract is required for home improvement projects over $500, and changes must be made by a signed written change order[2]. A swimming pool contract must include a plan and scale drawing showing the shape, size, dimensions and construction and equipment specifications. The contract should describe products and work in detail, include a detailed payment schedule, say who will obtain permits, give a completion date, cover clean-up and identify the contractor’s business address and license number. Any warranty should be in writing.
The contract must also include these notices[3]:
- The right to cancel within three business days of signing, if the contract was solicited somewhere other than the contractor’s place of business (cancellation must be in writing)
- A Notice to Owner about California’s mechanics lien law
- A description of what counts as substantial commencement of work
- A notice that failing to substantially start work within 20 days of the start date, without lawful excuse, violates Contractors License Law
- Whether the contractor carries commercial general liability insurance, and the insurer’s name
How should payments be made?
For a pool contract the down payment may not exceed 10 percent of the price or $1,000, whichever is less[4]. CSLB advises not paying in cash, not letting payments get ahead of the work, and not making the final payment until the final plastering is complete and any equipment, decking or fencing required by the contract is installed. Keep a job file of all papers, photographs, lien notices and warranties.
What if there is a problem?
CSLB suggests raising problems with the contractor first, in writing. If that does not resolve them, a homeowner can consult a lawyer or file a construction complaint with CSLB, which can be reached at (800) 321-2752[3].
How does San Diego Pools measure up on these checks?
On the public records: license 410251 is active in the C-53 classification, with a bond and workers’ compensation on file[5]; the company publishes its license number on its website; and BBB shows no complaints closed in the last three years[6]. Its published packages list inclusions and exclusions, and its warranty terms are in writing[7][8]. What a published page cannot show is the contract itself, so the payment schedule, notices and drawings above are still worth checking line by line. See license and credentials.
