Section 79: Powers of entry: with warrant
A lay magistrate may issue a warrant under this section authorising a person named in the warrant to enter and search the premises specified in the warrant. The warrant may only be issued if two conditions are satisfied:
A person acting on behalf of the council, reasonably requires to enter or search the premises to establish whether an offence has been committed, a requirement imposed by a notice has been or is being complied with or any of the matters mention in Section 77(1) (a), (b) & (c) (that is, whether living accommodation is an HMO, whether to grant, vary or revoke a licence, or whether to exercise any function under the Act).
The premises are unoccupied or temporarily vacant, or applying to the owners or occupiers for entry would defeat the purpose of the entry or the search, or entry has already been sought under Section 78 but has been refused.
The section sets out a number of safeguards governing the issue and execution of warrants.
