Pool Repair on Sanibel, FL: City Permits and Island Water

Pool repair on Sanibel

Pool work on Sanibel goes through the City of Sanibel Building Department, whose pool checklist and new permit-exemption guidance are specific to the island. The services on offer are the ones available across Lee County, among them pool resurfacing, leak detection, heater repair and pool deck resurfacing.

What the pool checklist asks for. Sanibel’s pool permit checklist goes further than a list of drawings:

• Renovations: “Pool renovation projects shall provide required information verifying that Entrapment protection for all existing suction outlets (drains) are in compliance with the requirements of ANSI/APSP 7.” In other words, a renovation has to show that the existing drains meet the entrapment standard.
• Equipment must comply with the Florida Building Code’s energy conservation section 403.9, “as applicable”.
• Pools whose pool and deck together exceed 1,000 square feet need an inspected temporary construction fence before the permit is issued.
• Once a slab is placed, work stops until the city has approved an Elevation Certificate and a spot survey.

The city’s pool and spa application, dated March 2026, has boxes for a pool heater, new or replacement, gas or electric, and for a deck. On the city’s permitting information page, “Contractors shall have the required licenses, registration, and insurance”; a state license can be checked at myfloridalicense.com.

The 2026 exemption, and what it leaves out. From July 1, 2026, the city says, state law (HB 803) exempts some single-family work from permits. Its own summary lists what is not eligible “regardless of cost”: electrical, plumbing, mechanical and gas work, structural work including pool barriers and fences, and any work on a property partly or entirely within a flood hazard area. Heater, pump and barrier work appears to fall within those categories; the Building Department is the place to confirm.

Water from deep brackish wells. Island Water Association describes itself as “a non-profit, member-owned water utility serving over 5,300 accounts on Sanibel and Captiva Islands.” Its 2025 report says the raw water comes from the Suwannee Aquifer, “approximately 700 to 900 feet below the surface”, and that its salt content “is the primary reason that Reverse Osmosis (R.O.) is used”. The utility’s own “How it’s made” page names the Suwannee and Hawthorne aquifers and wells of 500 to 900 feet, so the two pages differ on the detail. Either way, the water reaching a Sanibel pool has been through reverse osmosis, and the utility rates it mildly soft.

What is added to it. After reverse osmosis, IWA’s “How it’s made” page says, the water “is mixed with chlorine for disinfection and to remove naturally occurring hydrogen sulfide”, and sodium hydroxide and a corrosion inhibitor are added “for pH adjustment” and to keep copper in home plumbing from leaching. The utility’s FAQ gives a pH of 7.6 to 7.7. Those are the starting numbers a Sanibel pool owner balances a fresh fill from.

Homes that are older and owner-occupied. The Census Bureau’s American Community Survey (2020-2024) counts 8,564 housing units in the city, with a median year built of 1983. 37.5% date from 1979 or earlier and 49.2% from 1980 to 1999. 54.6% are single-family detached homes and 31.8% are in buildings of ten or more units. At 89.9%, the share of occupied homes lived in by their owners is the highest of any place this site covers.
