Heritage Regulation 2012

The following additional security measures must be taken for the protection of a building that is to be unoccupied for a continuous period of 60 days or more—

if an electronic surveillance or alarm system is installed, the system must be connected to a police station or a commercial security provider,

if no electronic surveillance or alarm system is installed, arrangements must be in place for regular surveillance of the building, work or relic, as appropriate to its nature and location.

This clause does not apply to any outbuilding within the curtilage or site of a building unless the outbuilding has been constructed or adapted for use as a dwelling.

The use of a building for storage of goods or materials does not constitute occupation of the building for the purposes of this clause if the building ordinarily has another use or is a building of a kind not ordinarily used for storage.
