[HISTORY: Adopted by the Village Board of the Village of
Grafton 11-18-2019 by Ord. No. 020-2019. Amendments noted where applicable.]
A.
Intent. The intent of this section is to provide a means for automatic
detection of fire conditions and/or to provide warning notification
throughout all buildings and occupancies built hereinafter, structurally
altered, and/or added to. Fire alarm systems are intended to provide
additional life safety and help reduce property loss through early
detection of fires, providing warning to occupants and automatically
notifying the Fire Department of fire.

contractor.
A.
Intent. The intent of this section is to require the installation
of automatic fire sprinkler, fire control and/or fire suppression
systems to improve the protection of life and property within the
municipality. It will establish a minimum standard for fire safety
through the standardization of the design, installation, testing and
maintenance requirements for automatic fire sprinkler suppression.
B.
Code compliance. All automatic fire sprinkler fire control and/or
fire suppression systems installed, modified, altered and/or repaired

reasonable time frame as determined by the Village Engineer. If the
property owner does not complete the specified corrective action by
the deadline specified by the Village Engineer, such corrective action
shall be undertaken by the Village. If the corrective action is undertaken
by the Village, the owner of the private property on which the fire
hydrant is located shall be liable for all costs and expenses incurred
by the Village for the corrective action, including but not limited
to the cost of any materials and the actual labor cost incurred by
the Village, through its employees, agents, or subcontractors.

public safety, or public health, the corrective action shall be undertaken
by the Village without advance notice to the property owner, and the
property owner shall be liable for all costs and expenses incurred
by the Village for the corrective action.
F.
