You are quite right, Anthony B, this fire officer would not normally have visited the property. Also, as it is now no longer classed as an HMO because there are only 2 people living at it (previously there were 3), the Housing Officer is no longer particularly interested in it.
BUT - and this is a big BUT - now that the fire officer has seen it, he is basing his opinion on his handbook and the interpretation of what is classed as 'a single private dwelling'. His interpretation is that the RRO applies to 2 or more unrelated sharers. However, he has since stated that his local authority is currently 'expecting guidance ...... with regard to the standards that we should be applying, but, as yet, they have not been published'.
IF the applicable number of occupants is 2 rather than 3 (as with HMOs), this really complicates matters. He further states that 'there are 2 pieces of legislation that apply to this type of property, the Housing Act 2004 and the Regulatory Reform (Fire Safety) Order 2005, RRO. Both acts impinge on each other with the Housing Act taking primacy'. The Housing Act I can deal with - the RRO is much too complicated for the likes of me!
Hopefully, the number will be agreed as 3 and then I will know where I stand!
