NOTE - The HHSRS assessment for Crowding and Space differs from other
Hazards. As with all Hazards, the dwelling is first assessed disregarding the current
occupiers. In most cases, this will mean that the dwelling will be satisfactory (ie,
average) having regard to the space available for sleeping, living and recreation. A
supplemental stage is necessary taking into account the current occupiers to
determine whether the dwelling is crowded - ie, is there a mis-match between the
size of the household and the dwelling. It is this Adjusted Hazard Score which should
be taken into account in deciding whether action is necessary.

RATING
As for all hazards, the current occupation is disregarded in the HHSRS assessment of
the dwelling. The dwelling provides adequate sleeping, living and recreational space for
up to 3 persons (irrespective of age and sex). On this basis, the dwelling is satisfactory.
However, there is a mis-match between the current occupying household and the house -
on which see below.

Unlike other hazards, with Crowding and Space the severity of the risk will depend on
the number of current occupants in the dwelling and the space available. In this case,
the household comprises 6 persons and this dwelling is suitable for occupation by 3
persons. This increases the likelihood of a harmful occurence, but not the spread of
health outcomes, giving a hazard score of 2,089 and a rating of band B.
