The Ontario Building Code is administered by the Building and Development Branch of the Ministry of Municipal Affairs and Housing. The Building Code is a regulation made under the Building Code Act. It:

• focuses primarily on ensuring public safety in newly constructed buildings, but also supports the government's commitments to energy conservation, barrier-free accessibility and economic development
• sets out objectives and requirements for new construction
• does not provide standards for existing buildings, with the exception of small on-site sewage systems
• establishes the qualification and registration requirements in Ontario for certain building practitioners
