Every Part 3 house must be licensed under this Part unless—
it is an HMO to which Part 2 applies (see section 55(2)), or
a temporary exemption notice is in force in relation to it under section 86, or
a management order is in force in relation to it under Chapter 1 or 2 of Part 4.
A licence under this Part is a licence authorising occupation of the house concerned under one or more tenancies or licences within section 79(2)(b).
Sections 87 to 90 deal with applications for licences, the granting or refusal of licences and the imposition of licence conditions.
The local housing authority must take all reasonable steps to secure that applications for licences are made to them in respect of houses in their area which are required to be licensed under this Part but are not so licensed.
In this Part, unless the context otherwise requires—
references to a Part 3 house are to a house to which this Part applies (see section 79(2)),
references to a licence are to a licence under this Part,
references to a licence holder are to be read accordingly, and
references to a house being (or not being) licensed under this Part are to its being (or not being) a house in respect of which a licence is in force under this Part.
