The Act does not forbid smoking on balconies or outside of homes, but a housing company may apply to the municipality for a smoking ban in certain areas, such as balconies. Municipal authorities will impose a smoking ban if, under normal conditions and for either structural or other reasons, smoke could spread, for example, from one balcony to another. The spreading of the smoke is sufficient for the ban; no evidence of damage to health is needed, in contrast to the procedures of the Health Protection Act. It is also possible to intervene with stricter requirements in situations where smoke spreads from one residence to another via the structures of the building.
