This might clear some things up...
From the National Fire Safety Protocol, from Lacors, signed by the Secretary of State for housing, and Secretary of State of fire safety:
Which authority should take the lead
enforcing role for fire safety?
The table below lists the authority that will
normally take the lead in inspection and
enforcement action in different types of
property.
1 Single dwellings, including shared
housing, (Fire risk assessment
not required) LHA
No RA therefore no RRO.
Not quite as simple as that Civvy.
Unshared private dwellings fall outside Article 2 of the Order. Where there is a shared house and the tenancy agreement demonstrates that residents have joint occupation, and the premises are their dwelling, the house will fall outside Article 2. For it will be a single shared house, rather than a building containing parts used in common by the occupants of more than one private dwelling.
The position is more complicated in respect of premises where the tenancy agreements disclose exclusive occupation of bedrooms, but common use of other parts of the premises, such as kitchens, bathrooms and sitting rooms, along with facilities in the premises.
Where a tenant has significant and substantial use of shared parts, this will result in the bedroom being just part of the tenant’s dwelling, rather than his dwelling.
There are no conclusive tests to determine what will be sufficiently significant to identify whether premises are a part, or the whole, of the tenant’s dwelling, the existence of a shared sitting room will be an indicator that the exclusively occupied bedroom is only part of the tenant’s dwelling. In such circumstances, should this indicator, and the range of other circumstances in the premises, evidence that the sharing of areas is significant and substantial, the tenant will not have a separate dwelling. The Order will, therefore, not apply.
and finally just to be picky.....we shouldnt really use the term RRO, there are many RROs but only one fire safety order.
