Bill or Act:
Summary of Decision:
O. Reg. 191/14, regarding wood frame construction, amends O. Reg. 332/12 (Building Code) made under the Building Code Act.
Changes to the Building Code allowing up to six-storey wood-frame buildings starting January 1, 2015.
The changes give builders a safe option that can help make building a home more affordable and support more attractive, pedestrian-oriented buildings that enhance streetscapes while continuing to protect the safety of residents and firefighters.
New safety requirements for wood frame buildings that include building stairwells with non-combustible materials and roofs that are combustion resistant now make Ontario's regulations the most rigorous in Canada.
Safe and flexible building options that help make housing more affordable and support our forest industry is part of the government's plan to invest in people, build modern infrastructure and supporting a dynamic and innovative business climate.

Summary of Proposal:
The Ministry of Municipal Affairs and Housing (MMAH) is proposing amendments to Ontario Regulation 332/12 (Building Code) under the Building Code Act, 1992. The purpose of the proposed amendments would be to permit the construction of up to six storey wood-frame buildings. The Building Code currently permits the construction of up to four storey wood-frame buildings.
To facilitate mid-rise wood frame construction for residential buildings and office buildings, MMAH is considering the following amendments to the Building Code regulation:
-To facilitate mixed uses, certain other building uses would be permitted on the first and second floors of mid-rise wood frame residential or office buildings, including restaurants, stores, and medical offices.
-Limits on building height to top floor (18m from first floor, 20m from fire access route)
-Limits on building area to 25% of that of non-combustible buildings
-Minimum building perimeter requirements
-Non-combustible stairwells with a fire-resistance rating of at least 1.5 hours
-Enhanced automatic sprinklering, including balconies and decks
-Increased fire protection in concealed spaces
-Non-combustible exterior cladding
-Combustion-resistant roof cladding
-Improved fire service access to the building
A policy paper providing further details of the proposed changes will be available online until May 4, 2014.
