Yes. If local regulations are not as strict as LEED you must create a policy that complies with LEED standards (and communicate this policy to building users) to achieve this prerequisite. Exterior signage that communicates the policy is required so that all occupants, visitors, and passersby are made aware of the exterior smoking policy.
Municipal law requires that our building be completely smoke-free inside. It also bans smoking next to the building, but it’s not as stringent as the 25 foot LEED requirement. Do we have to make another policy that bans smoking within 25 feet?
