What does a C-53 license allow?
CSLB defines a C-53 Swimming Pool contractor as one who constructs swimming pools, spas or hot tubs, including installation of solar heating equipment, using trades and skills such as excavation, steel placement, plumbing, shotcrete and finish work[2]. CSLB’s homeowner guidance adds that any pool job costing $1,000 or more must be done by a contractor licensed in the classification for the work, and that a general building contractor may also contract for pool work only in the ways the rules allow[3].
What do the bond and workers’ comp entries mean?
A contractor bond is a surety bond filed with CSLB as a condition of holding a license; the record names the surety, the bond number and the amount. A bond is not insurance for the homeowner’s project, and its amount is small compared with the cost of a pool. The workers’ compensation entry shows the license holder reported having employees and filed proof of coverage, which fits the company’s statement that most of its work is done by its own employees. Liability insurance is a separate matter: CSLB says a pool contract must state whether the contractor carries commercial general liability insurance and name the insurer[4].
What does the BBB profile say?
The Better Business Bureau profile lists San Diego Pools as BBB-accredited since 3 August 2011 with an A+ rating, and showed no customer complaints closed in the last three years when checked[5]. It lists the business start as 4 July 1976, incorporation on 31 October 2011, the alternate name Crown Us Inc, and Kenneth William King III (owner) and Katie King-Acosta (manager) as management. BBB ratings and accreditation are BBB’s own programmes, not government licenses.
What memberships and affiliations does the company show?
The company’s pages display badges for APSP membership, BBB accreditation, Pentair and Yelp[6]. APSP stands for the Association of Pool & Spa Professionals, a trade association. This reference has not confirmed a current membership listing; the company is the best source for which memberships are current.
How do I check the license myself?
- Open the CSLB license check page and search for license number 410251, or the business name “San Diego Pools”.
- Confirm the status is active and the classification is C53 (or that the contractor holding the contract has the classification for the work).
- Open the personnel list to see who is named on the license.
- If a salesperson visits you at home, ask to see their home improvement salesperson registration and check that it lists the company.
Those steps follow CSLB’s own advice for pool projects[3].
