Do we need to prohibit smoking on the roof of a multi tenant office, hotell and retail building. The architect have designed an outdoor environment on the roof including vegetations, pounds, open space (teracce), hot spots for social acitivity etc. We anticipate many tenants and visitors want to use this roof space to smoke.
Is is enough to prohibit smoking 25 feet from entries, outdoor intake and operable windows? Or is the only way forward do prohibit smoking over the entire roof?
