The installation of an alarm system within the Village of Spring Grove requires a permit. The State of Illinois requires all persons, firms, or companies that advertise and install alarm systems to be licensed by the State. Applications for an alarm system installation should be submitted to the building department. It will then be forwarded to the Chief of Police to verify the contractors licensing status with the State. This is a very inexpensive permit that is set-up to protect the residents of Spring Grove from non-complying alarm contractors. The last thing a homeowner who is seeking to add security to their home wants to do is have the system installed by an unknown person, firm, or company.
