2012 Building Code

Ontario's building regulatory system has undergone significant changes. Whether you are proposing to build a new commercial building, renovate an office, build a new home or plan to construct an addition to your own home, this new legislation will affect you.

Ontario’s new Building Code (2012) has been approved and replaces the previous building code regulation released in 2006. The new Code includes many new provisions and several hundred technical changes in the minimum standards for building construction across Ontario.

While most of the requirements of the new Code came into force on January 1, 2014, there were also transitional provisions with respect to permits issued before December 31, 2013, or where working drawings, plans and specifications were substantially completed before December 31, 2013.

Supplementary SB-12 “Energy Efficiency for Housing” Amendments

On July 7, 2016 the Ministry of Municipal Affairs and Housing (MMAH) released amendments to Supplementary Standard SB-12. Building permit applications received after December 31, 2016 will be required to conform to the new SB-12 amendments, highlights from the Code News below:

·New prescriptive compliance packages that provide minimum 15 per cent energy efficiency improvement over existing packages

· Drain water heat recovery units as a mandatory requirement for all prescriptive compliance packages

·Heat or energy recovery ventilators as a mandatory requirement in all packages in order to protect indoor air quality as homes get increasingly “air tight”

· Thermal U and effective RSI values along with nominal RSI values to provide added flexibility in the choice of different assembly structures e.g. basement wall and roofs

· Credits for reducing air leakage to encourage better energy conservation

· Table to clarify requirements for developing a reference building

· Revised air-leakage rates for the reference building to encourage testing and improved air tightness

· Clarification to provide credits for renewables, dedicated ventilation systems and broader types of HVAC equipment

·Refer to Supplementary SB-12 “Energy Efficiency for Housing” Amendments

O.B.C. Sewage Systems – Part 8

Effective January 1, 2017: CAN/BNQ 3680-600, “Onsite Residential Wastewater Treatment Technologies” is the new national standard for testing wastewater residential treatment technologies. This will affect sewage system designers, treatment manufacturers and installers.

This standard will replace the current criteria for treatment units set out in the Ontario Building Code, and the list of treatment units found in Supplementary Standard SB-5 which are deemed to meet these Code requirements.

Supplementary Standard SB-5 will be revoked on January 1, 2017 and many of the existing Building Materials Evaluation Commission (BMEC) Authorizations have since been revoked.

Construction Site Fencing

Construction that occurs adjacent to pedestrian walkways/roadways, with close proximity to occupied buildings, and areas close to schools, parks, recreational or other public facilities must be fenced or hoarded to prevent access. Prior to commencing construction contact Building Services for specific requirements.

Designer Qualifications

The Ontario Building Code Act requires designers of certain construction projects to be pre-qualified in the knowledge of the Ontario Building Code by writing and passing technical exams. Designer qualifications vary based on the scope and nature of the design activity undertaken; however, if you are the owner of a house, you are allowed to take responsibility for the design, preparation of the plans, and specifications, without having to be pre-qualified. This includes the construction of a new house, addition, renovation, or the construction of an accessory building, such as a garage, shed and deck.  Also, the homeowner may take responsibility for sewage system design and construction.

If you are considering hiring a design consultant, you need to ensure that your design team is qualified and registered for the type of project you are proposing. Designers are required to declare their registration, qualifications, and design responsibility on the provincial Building Permit application form and on every Building Permit submission document.

Architects are qualified and registered by the Ontario Association of Architects and Engineers are qualified and registered by the Professional Engineers of Ontario.

Architects and Engineers are not required to be registered or qualified with the Ministry of Municipal Affairs and Housing.

As the owner of the property, you are responsible for ensuring that you have hired qualified people. For more information regarding designer qualification and exemptions, please contact the Ontario Ministry of Municipal Affairs and Housing (MMAH). Designer qualifications can be viewed through the MMAH or by accessing their on-line Public Registry(QuARTS).
