If you have a ‘feature’ that bco would wince at say for example a dodgy temporary staircase - would that deem it not habitable? . So you live on site but not habitable . Another condition we all need is fire alarms - yet I have none installed . So bco might deem these things as not complete . I’m just concerned as I get the robot from the council out for tax valuation they obviously have to add the property to the list - but I don’t want the word habitable anywhere .
Perhaps get the fire brigade to take a look ? . Fairly certain they will be shocked - they surely could write a short letter stating ‘ dangerous ‘ , ‘ incomplete’ and not fit for habitation perhaps ???
