Before a facility manager signs off on a lightning protection budget, the first question is almost always the same: what is this actually going to cost? It’s a fair question, and the honest answer is that lightning protection system cost varies more than most contractors will tell you upfront. A single-family home in Clearwater might run $450 to $2,681. A mid-size commercial building in Tampa can land anywhere between $10,000 and $35,000. A hospital campus with a helipad, server rooms, and a medical-grade grounding requirement? That number climbs higher still. This guide breaks down what drives those ranges, what you should expect to pay at each building type, and how to frame the investment as a financial decision — not just a safety checkbox.
