2.1 Basic Dwelling Unit Definition
The Municipal Act and Zoning By-law definition for a residential unit or “Dwelling Unit” includes the following characteristics:
2.2 Types of Residential Dwellings
Below are the traditional types of residential dwellings which are typically permitted in Residential Zones only.
Single-Detached Dwelling
A separate residential building containing only 1 Dwelling Unit (ie a house).
Semi-Detached Dwelling
The whole of a building divided vertically into 2 single Dwelling Units by a solid common wall extending throughout the entire structure, from the base of the foundation to the highest point of the roof line with each unit having an independent entrance directly from the outside.
Townhouse
A building divided vertically into not less than 4 and not more than 8 attached, non-communicating Dwelling Units.
Street Townhouse
A Townhouse with each Dwelling Unit on a separate lot with frontage on a street.
Duplex
The whole of a building divided horizontally into 2 separate Dwelling Units, each of which has an independent entrance.
Triplex
The whole of a building divided into 3 separate Dwelling Units, each of which has an independent entrance, either directly from outside or through a common vestibule.
Fourplex
The whole of a building divided into 4 separate Dwelling Units, each of which has an independent entrance, either directly from outside or through a common vestibule, but does not include a Townhouse or Street Townhouse.
Apartment Building
The whole of a building containing 5 or more Dwelling Units and which has a single common entrance.
Boarding/Lodging House
A Boarding or Lodging House is defined in the Zoning By-law as “a dwelling in which the proprietor supplies, for gain lodging, with or without meals, to more than 3 persons, but does not include a Group Home, Hotel, Hospital, Nursing Home, or other establishment otherwise classified or defined in this By-law”.
Boarding, Lodging and Rooming Houses are regulated in the Ontario Fire Code as “houses and private rest homes” in which residents do not require care or treatment because of age, mental or physical limitations, where:
Bed and Breakfast
A Bed and Breakfast is permitted in a Single-Detached Dwelling occupied by the owner and used incidentally for commercial purposes to provide overnight accommodation and meals to the traveling and vacationing public, but does not include a Boarding or Lodging House, Hotel, Hostel, Group Home or other establishment otherwise classified or defined in this By-law.
Group Home
A Group Home is defined in the Zoning By-law as a Dwelling Unit in a Residential Zone in which 3 to 6 residents, who require specialized, personal care, live under responsible supervision.
A Group Home is not defined in the Ontario Fire Code, but the Code regulates most types of care facilities under section 9.4 or 9.3. There are Fire Code exemptions for residential occupancies regulated under the Ministry of Community and Social Services.
Dormitory
A student dormitory is not defined in the Zoning By-law but is permitted only on lands owned by a College, or other premises exempt by the Zoning By-law.
Other Uses Not Specifically Defined or Permitted
Other residential-type uses such as hostels, hospices, shelters, halfway houses, seasonal camps, etc. may or may not be permitted depending on the exact nature of the use and the Zone in which it is proposed. Please consult with City staff for more information.
4.1 Boarders
Nothing in any of the laws above can prevent the keeping of not more than 2 roomers or boarders in any Single-Detached Dwelling, Semi-Detached Dwelling, Triplex, Fourplex or Townhouse. On the east side of the new canal, the provision is similar but worded somewhat differently.
In this instance the boarders cannot have a separate dwelling unit and must live within the confines of the existing single dwelling unit. This essentially implies renting a sleeping room only.
4.2 Two Unit Houses
Notwithstanding any existing City Zoning By-law in Ontario, the Province of Ontario has amended the Planning Act as follows:
Other regulations which may restrict the second unit are the Ontario Fire Code section 9.8, and the City Property Standards By-law.
For further information refer to City brochure “Apartments in Houses”.
4.3 One Dwelling Unit
Notwithstanding any existing City Zoning By-law in Ontario, the Province of Ontario has amended the Planning Act as follows:
This amendment resulted from changes in the traditional family whereby it became impossible to restrict previous “Single-Family Zones” to persons who were related, without promoting discrimination. The change necessitated the concept of a Single-Detached Dwelling and a Single Dwelling Unit.
Unrelated persons can live together in a Single Detached Dwelling or in 1 Dwelling Unit provided the manner in which the building is used complies with the definition of a Dwelling Unit previously described in this brochure. A key feature is using the unit as a “single housekeeping unit in which no occupant has exclusive possession of any part of the unit”. This clearly implies a group sharing arrangement where no rooms are locked and where everyone has equal access to all areas. Bathrooms and kitchens are shared as in a traditional family. A proprietor cannot live at the premises and exercise control over tenants.
The concept was tested recently in a St. Catharines Court Case where several unrelated students rented a “detached house” as a group. The Court determined that since all students as a group leased the complete house under one Tenancy Agreement with a single monthly lump sum rental payment, it should properly be defined as a Single Detached Dwelling and not a Boarding, Lodging or Rooming House. The Justice further stated that social concerns such as noise, parking, traffic and littering should be dealt with by the by-laws specifically passed for those purposes and not by land use by-laws.
The Fire Department has requested the owner and occupants to contact the City Fire Prevention Officers in any case, to review the fire safety issues of such houses with respect to the Fire Code.
