Where it comes to the knowledge of the landlord of a dwelling, or of his agent, that the dwelling is overcrowded, then, except in the cases mentioned in subsection (2), the landlord or, as the case may be, the agent shall give notice of the fact of overcrowding to the local housing authority within seven days after that fact first comes to his knowledge.
The obligation to notify does not arise in the case of overcrowding which—
has already been notified to the local housing authority,
has been notified to the landlord or his agent by the local housing authority, or
is constituted by the use of the dwelling for sleeping by such number of persons as the occupier is authorised to permit to sleep there by a licence in force under section 330 (licence of local housing authority).
A landlord or agent who fails to give notice in accordance with this section commits a summary offence and is liable on conviction to a fine not exceeding level 1 on the standard scale.
