Thats where it gets complicated Red , there are lots of laws involved , the front of the property is in one district the back is in another , so both sets of rules apply , also since not ony has it got neighbouring houses it by chance adjoins a nature reserve which brings in more regulations .
It is not a building codes issue really it is a health and safety one ,together with some public nuisance for good measure . Mainly involving fire risk , noxious fumes and an unpleasant smell .

This is to explore the myth about rights without responsibilities from the closed "smoking" topic but without the emotional baggage that some dragged into that .
