A building protection system includes a switch, a transmitter, a receiver and a controllable shut-off valve disposed within the inlet line of a utility, such as water or gas, provided to a building. The switch is used to close or open the shut-off valve to stop the flow of the utility into the building. The receiver is proximate the valve, while the transmitter and switch are remote from the valve. In one embodiment, the switch is a manual switch that can be used to generate a valve open or a valve closed signal. The switch and transmitter can be wall-mounted, such as in a garage, or can be integrated into a hand-held device, such as a remote control. In other embodiments, the switch is associated with a condition sensor, such as for sensing a utilities leak or for sensing a temperature outside a certain pre-determined limit value. In still further embodiments, the building protection system includes an auto-dialer for automatically dialing a pre-determined list of phone numbers in response to a sensed condition or in response to closing the utility shut-off valve.
