What does it entail to retrofit a property with second suites?

I am sure many of us have come across listing or selling residential properties which have second suites, or commercial properties which have a residential component. Second suites can provide affordable housing for tenants, at the same time let tenants help pay the mortgage. Second suites may occupy a space at the back of the home, the upper floor or the basement.

In 2000, City of Toronto came out with a new provision that homeowners in the 416/647 area code in single or semi-detached homes are permitted to house second suites. To ensure safety standards for all residents, second suites must meet code compliance as follows:

• zoning requirements
• property and occupancy standards
• health and safety standards
• fire and electrical codes

The typical process for a property with an existing second suite:

• Municipal Licensing and Standards Zoning Property and Occupancy Standards Review
• Fire Safety
• Electrical Safety

The typical process for a property with a new  second suite: [If the home has never had a second dwelling, or if there is existing roughed in and you wish to install a kitchen and bathroom, then it will be considered as a new second suite]

• Buildings Division and Building Permit
• Fire Safety
• Electrical Safety

To prove that your property has been adjusted with an existing second suite previously, the building department officials may need documentation that the unit already existed. Otherwise it will be interpreted as new.
