Section 661.200 - Smoking in Outdoor SpacesSmoking may be permitted in an outdoor space, provided that the outdoor space is physically separated from an enclosed work space and there is no migration of smoke into the work space.
(1) In accordance with M.G.L. c. 270, § 22, any outdoor space that has a structure capable of being enclosed, regardless of the materials or removable nature of the walls or covers, shall be regarded as an enclosed space when the walls or covers are in place.(2) The outdoor space shall be open to the air at all times. For purposes of 105 CMR 661.000, this shall mean that the space has thorough, unobstructed circulation of outside air to all parts of the outdoor space. An outdoor space shall be presumed to meet this test if: (a) the space has a ceiling and at least one half of the total surface area of the walls and other vertical boundaries of the space permits unobstructed flow of outside air into the space; or(b) the space has no ceiling and no more than two walls or other vertical boundaries of the space that obstruct the flow of air into the space exceed eight feet in height.(3) For purposes of 105 CMR 661.000, a ceiling shall include any top or covering that is placed or maybe placed over a space, or any other structure or arrangement above the space (including substantial coverage by umbrellas or awnings) that may impede the flow of air into the space, regardless of the type or nature of the materials or the partial or removable nature of the covering.(4) The local board of health shall be notified in writing prior to initiating construction or renovation of an outdoor space for the purpose of permitting smoking, if such construction or renovation requires notification of the local building department or a licensing authority.
