So the situation is that from July 1 2019, all rental properties must have insulation in the ceiling and under floors "where practicable". Seems fairly straight forward so far.
I have a 1970's rental property which is in a 2 storey block of 10. My particular unit is on the first floor, but there is no unit underneath on the ground floor - the entire space under my unit is occupied by 3 parking spaces, and only one of these spaces belongs to my unit. Essentially my unit is suspended in mid-air and held up by concrete block walls on 3 sides, with the 4th side open to allow vehicles to park underneath.
The floor of my unit is made of cast concrete panels, and is obviously held up by the 3 concrete walls downstairs along with a chunky concrete beam where the opening is.
I am wondering how practicable it is for me to install underfloor insulation, and what type I could use. I obviously own the top side of my concrete floor. And presumably I also own the underside of my floor - the ceiling above my designated parking space. But one potential sticking point could be that I don't know who owns the underside of my floor where the other two parking spaces are. Technically the underside of my floor is the ceiling of those parking spaces, so it could be argued that the two neighbouring property owners actually own two thirds of the ceiling space below my unit, so it may not be practicable for me to install insulation in those two areas unless the other owners agree. There are electrical wires which don't belong to me running across that ceiling area which complicates things further - I most likely have no right to cover those cables up, but nor am I enthralled at the thought of having to pay to relocate those cables.
It's an interesting conundrum. Whilst I would like nothing better than to turn up there tomorrow and apply insulating spray foam to the whole ceiling of the carport area, I feel like that could potentially be considered trespassing, and of course there is the cabling issue to address first.
At this stage I don't know who the other owners are. It's a case of traipsing down to the council offices to find out their name and address for service, and then sending them letters I guess.
It's a long shot, but has anyone else found themselves in a similar situation?
