The details seem to be easier that your OP? Or do the stair lighting etc still apply? I agree we want better houses, but there needs to be common sense. Your OP stated that it needs celling insulation, and if the ceiling is not accessible it needs to be. Well, are we talking 10k here????
We do need a minimum, but it smacks of someone in an office writing down an ideal rental. Being clean, and dry and safe should just be about repairs and a few updates. It doesn't need to be a Health Award winning home, it just needs to be dry and warm.
They should have fired the 22yo graduate and hired a sparky, plumber and builder to draft the report.
