(1)If in the opinion of the local housing authority the condition of a house to which an order under section 370 applies (order applying management code) is defective in consequence of—
(a)neglect to comply with the requirements imposed by regulations under section 369 (regulations prescribing management code), or
(b)in respect of a period falling wholly or partly before the regulations applied to the house, neglect to comply with standards corresponding to the requirements imposed by the regulations,
the authority may serve on the person managing the house a notice specifying the works which, in the opinion of the authority, are required to make good the neglect.
(2)If it is not practicable after reasonable inquiry to ascertain the name or address of the person managing the house, the notice may be served by addressing it to him by the description of “manager of the House” (naming the house to which it relates) and delivering it to some person on the premises.
(3)The notice shall require the person on whom it is served to execute the works specified in the notice within such period, not less than 21 days from the service of the notice, as may be so specified; but that period may from time to time be extended by written permission of the authority.
(4)Where the authority serve a notice under this section on the person managing a house, they shall inform any other person who is to their knowledge an owner, lessee or mortgagee of the house of the fact that the notice has been served.
(5)References in this section to the person managing a house have the same meaning as in section 369 (and accordingly are subject to amendment by regulations under that section).
