Pool service sits on a line most trades never have to draw. The same truck does work that needs no license and work that does, sometimes on the same visit, and where that line falls decides what you may put in an ad.
Florida. Chapter 489 of the Florida Statutes sets out three pool licenses: commercial pool/spa contractor, residential pool/spa contractor and swimming pool/spa servicing contractor. Water treatment that needs no equipment work needs no license, and neither does cleaning a pool in a way that leaves its structure and equipment alone. Repairing or replacing existing equipment, installing new equipment, adding a heater, replacing perimeter or filter piping, and cleaning that means taking equipment partly apart are servicing contractor work, though filter changes are excluded. Once a company holds a license, the number belongs in every offer of services, bid, contract and advertisement, regardless of medium, and a missing number draws a notice of noncompliance first, then a possible fine if it is not fixed within 30 days.
California. The Contractors State License Board’s C-53 Swimming Pool Contractor builds pools, spas and hot tubs, including solar heating equipment. Every licensee has to put its number in all forms of advertising, in the statute’s words. The contractor law does not apply to a job under $1,000 in total, labor and materials included, that needs no building permit.
Arizona. The license number carries the letters “ROC” in front of it on published advertising, and on internet ads unless the ad links straight to a page showing the licensee’s name and number. Anyone relying on the small-job exemption loses it by advertising without the words “not a licensed contractor.”
Commercial pools. The federal Virginia Graeme Baker Pool and Spa Safety Act requires public pools and spas, a definition that takes in pools for apartment complexes, residential developments and hotels, to be equipped with anti-entrapment devices or systems that meet the ASME/ANSI A112.19.8 standard. One with a single main drain that is not unblockable also needs at least one backup, such as a safety vacuum release system or an automatic pump shut-off. A violation counts as a violation of the Consumer Product Safety Act. Backyard pools are outside that section, which is why a commercial bid and a residential page should never share copy.
The Pool & Hot Tub Alliance says it plainly: there is no uniform state licensing for pool professionals. So the plan starts with a written list of what you are licensed to do in each state you work in, and the ads say exactly that and nothing more.
