Collier is the largest county in Florida by land area, and only about nine per cent of its residents live inside a city. Naples, Marco Island and Everglades City are the only incorporated places. Everything else, including Golden Gate, Immokalee, Pelican Bay and the whole of Golden Gate Estates, is unincorporated county.
It is also tile country. A great deal of Collier housing carries concrete or clay tile, and tile hides its problems well: the tile itself often outlives the underlayment beneath it by a decade. Knowing whether you need a lift and relay or a full replacement is usually the whole question here.
