Definitions for these terms are required because, in some situations, the function and availability of some of the grounds for possession under Schedule 2 are determined by provisions linked to these terms, as set out below:
the application of the one year- restriction on use of Grounds 1A and 6 month restriction on use of Ground 6 at the start of a tenancy may be determined by whether a "notice of a compulsory acquisition" was given and an "acquiring authority" intends to acquire or redevelop the property.
the use of Ground 6B may be determined by whether the housing meets HMO regulations.
the use of Ground 5F may be determined by whether a tenant lives in "managed accommodation". The application of Grounds 2ZA, 2ZB, 5E, 5F and 18 is determined by whether the housing meets the definition of "supported accommodation" (which incorporates "support services", as separately defined).
the use of Grounds 1, 1A, 2ZA, 2ZB, 4A, 5F, 5G and 6 are linked to a "relevant date". In most cases, this date is the date specified in the section 8 notice, or, for Grounds 2ZA, 2ZB or 5F, the date when that notice is served; but where the court uses its power to dispense with the requirement for notice, the "relevant date" will be the date on which proceedings for possession began.
	A definition for "housing association" is required because the definition of ‘"supported accommodation" in the Act refers to "housing association". A "housing association" is included on the list of specified landlords that may provide ‘supported accommodation".
	The definitions of "HMO" and "housing association" are taken from the Housing Act 2004 and the Housing Associations Act 1985, respectively.
