Rules another office applies inside Town of Weston

Town of Weston does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

• Building code adoptedAdopted

  • This record rests on the Town by-law's cross-reference to the state building code, not on a Town adoption ordinance. The state code itself was not opened.

  “Terms or words not defined in this Section or elsewhere in this By-Law, but defined in the latest edition of the State Building Code (780 CMR), or in the Massachusetts General Laws, shall have the meaning given therein.”
