Pool Bonding and Grounding: What Fails Inspections in Older Sarasota Waterfront Homes | CoHarbor Electric

We walked a property near Casey Key a while back for a buyer’s inspection — gorgeous older home, pool right off the lanai, the kind of place that looks like it hasn’t had a single problem in forty years. Inspector flagged the pool bonding within about ten minutes of getting to the equipment pad. Turned out the bonding grid had been partially disconnected years earlier during a deck resurfacing job, and nobody ever tied it back in. Nothing visibly wrong. No sparks, no tripped breakers, nothing the homeowners had ever noticed. Just a code violation quietly sitting there the whole time, waiting for someone with the right eyes to look for it.

That’s pool bonding in a nutshell. It’s one of the least visible things on a property and one of the most commonly flagged items on an inspection, especially in a market like Sarasota where a huge share of the housing stock has a pool.

Why Pool Bonding Gets Its Own Rulebook

Most electrical work in a house falls under the general provisions of the National Electrical Code. Pools, spas, and the equipment around them get their own dedicated section — NEC Article 680 — because water and electricity together create a genuinely different risk profile than a kitchen outlet or a bedroom ceiling fan. Article 680 exists to keep stray voltage from ever having a path into the water or the surrounding deck, and bonding is the mechanism that does that.

Bonding isn’t the same thing as grounding, even though people use the words interchangeably. Grounding gives electricity a path back to the source in the event of a fault. Bonding ties all the metal components around a pool — the rebar in the deck, the pump housing, ladders, handrails, the pool light niche, metal fencing within range — into one electrically continuous system, so nothing near the water can develop a different electrical potential than anything else near it. If bonding is broken or incomplete, you can end up with a situation where a piece of metal near the pool is carrying a small stray voltage that has nowhere to safely go. That’s the scenario Article 680 is built to prevent.

What This Looks Like in an Older Sarasota Home

We see this most often in homes built before pool bonding requirements were as thorough as they are today, and especially in properties that have had any kind of deck, pool, or landscaping work done since — decades of homes around Manasota Key and Osprey fall right into that window. Every time someone resurfaces a deck, replaces a pool light, upgrades equipment, or does landscaping near the bonding grid, there’s a chance for a connection to get cut, corroded, or simply never reconnected. Nobody’s doing this maliciously. It’s usually just a subcontractor who wasn’t thinking about the bonding grid because bonding a pool wasn’t their job that day.

Salt air compounds the problem here in a way it wouldn’t further inland. Bonding connections are typically bare copper conductors and clamps, and coastal humidity and salt exposure corrode those connections faster than they would in a drier climate. A bonding connection that was solid a decade ago can be compromised today just from environmental wear, with nobody having touched it.

What an Inspector Is Actually Checking

For a home with a pool, an inspector working through the electrical portion of a purchase or 4-point inspection is typically looking at:

• Continuity of the bonding grid around the pool structure itself
• Bonding of the pump, filter, heater, and any other equipment on the pad
• GFCI protection on pool pump circuits and any pool-adjacent receptacles — required under NEC 680 regardless of when the pool was built
• Condition of the equipment disconnect near the pad
• Whether pool lighting fixtures are properly bonded and rated for wet-location use
• Any visible corrosion or disconnection at bonding lugs and clamps

Most of this isn’t visible just by looking at the pool. It requires actually accessing the equipment pad and, in some cases, testing continuity with a meter — which is part of why this gets missed by homeowners doing a casual walk-through before listing or buying.

Why This Matters More for Buyers Than It Might Seem

If you’re buying an older waterfront property in Sarasota with a pool, bonding issues are exactly the kind of thing that’s invisible until someone with the right training looks for it — and exactly the kind of finding that turns into a real repair cost, not a cosmetic negotiation point. Reconnecting or repairing a bonding grid isn’t usually a massive job, but it does typically require pulling a permit with Sarasota County and getting it inspected once the repair’s done, since it’s life-safety-related work, not routine maintenance.

We’d rather a buyer know this going in than find out from their own post-closing inspector three months after they’ve moved in.

The Mistake We See Most Often

Assuming that because the pool’s been in use for years without incident, the bonding must be fine. Bonding failures don’t usually cause a dramatic event. They sit there as a latent risk — a “this shouldn’t be the case, but nothing bad has happened yet” situation — right up until a fault occurs somewhere in the system and there’s no safe path for it to go. That’s exactly the kind of risk a 4-point or purchase inspection is designed to catch before it becomes a real problem, not after.

The second mistake is treating any pool-adjacent electrical work as something a pool contractor’s electrician fully handles on their own. Pool contractors are excellent at pool equipment. Bonding grid integrity, especially on an older property where decades of unrelated work may have touched it, is worth a dedicated look from an electrician who’s specifically checking Article 680 compliance, not just installing new equipment.

Getting a Bonding Issue Fixed

If bonding comes back flagged on an inspection, the fix usually involves reconnecting or replacing compromised bonding conductors, re-terminating corroded connections, and confirming continuity across the full grid with a meter. It’s typically a same-day job for a straightforward repair, though anything requiring deck or equipment pad access can take longer. Sarasota County requires a permit and inspection for pool bonding repairs, and that inspection is usually scheduled within a few business days of the call.

Have Your Sarasota Pool’s Bonding Checked by Coharbor Electric

If you’re buying, selling, or just own an older waterfront home in Sarasota, Casey Key, Osprey, or anywhere nearby with a pool on the property, it’s worth having the bonding and grounding checked by someone specifically looking for Article 680 compliance — not just a general walk-through. Coharbor Electric is licensed and insured, and we’ve found more than a few quietly disconnected bonding grids on properties that looked, and functioned, perfectly fine on the surface. We can’t promise every pool passes inspection with zero findings, but we can promise an honest look at what’s actually happening at the equipment pad. Reach out to Coharbor Electric before that bonding issue becomes someone’s discovery instead of yours.
