Abstract: A sprinkler regulation marking template for facilitating marking of a structure to provide an indication of space which must be left unobstructed to permit proper functioning of sprinklers. The sprinkler regulation marking template includes a main member that has an abutment portion and an extension portion. The abutment portion has a straight edge designed for positioning against a ceiling proximate a sprinkler. The extension portion extends from the abutment portion and includes a plurality of holes. Each of the holes is positioned in spaced relationship to the straight edge such that each hole is positioned for facilitating placing a mark on a structure beneath the ceiling such that the mark is positioned an associated pre-determined distance away from the ceiling for providing a visual indication of a spraying area of the sprinkler for facilitating positioning of objects outside of the spraying area to prevent interference with functioning of the sprinkler.
