Future buyers of condos lacking sprinklers will undoubtedly discount the value of those condos to reflect that fact, and conversely current owners of those units will achieve an economic benefit from their installation. If public money is to be used to pay for improvements to privately owned buildings, then the public must be assured that a mechanism is in place to recapture that increase in value when those condos are sold in the future. Otherwise current owners will be receiving a windfall profit because the public has paid to remedy their lack of foresight.
