It defines occupancy arrangements so that this Part relates to formal tenancies and the full range of formal and informal occupancy arrangements including shared accommodation. It also defines family and defines antisocial behaviour as, for the purposes of this Part, affecting persons at or in the locality of the relevant house. Anti social behaviour is construed for the purposes of Part 8, as it is for Part 7, as behaviour which causes or is likely to cause alarm, distress, nuisance or annoyance at or in the locality of the house.
