Secondary Dwelling Units in Greater Sudbury

SECTION 1:

New Provisions in the City of Greater Sudbury

On July 12, 2016, City Council approved the amendment to the Official Plan and Zoning By-law 2010-100Z to permit Secondary Dwelling Units within the City of Greater Sudbury. This follows The Strong Communities through Affordable Housing Act, which requires that municipalities across Ontario amend their planning documents to facilitate the creation of secondary units. Secondary dwelling units provide a form of affordable housing and help owners offset the cost of homeownership. http://www.qreatersudburv.ca/business/zoninq-bv-laws/ What is a Secondary Dwelling Unit? A secondary dwelling unit is a separate living space with a kitchen, bathroom, sleeping and possibly shared laundry facilities or a space with the required connections and hook-ups, located on the same property like your house (detached, semi-detached, row or street townhouse). You can live in it, allow your family members to live in it, or rent. It cannot be severed from a lot of the primary dwelling unit and/or sold. There are three different types that may be constructed in the City of Greater Sudbury;

SECTIONS 3: Zoning Requirements for Creating a New Secondary Dwelling Unit There are basic requirements that must be met before an authorized secondary dwelling unit can be created. Before constructing a new secondary dwelling unit, your property must meet the following requirements:

1. The primary dwelling unit must be a single-family, semi-detached, row or street townhouse dwelling or a building accessory thereto;

2. Only one secondary dwelling unit will be permitted per lot;

3. The exterior facade cannot have an additional entrance facing a public road or an additional exterior entrance above the first storey;

4. No additional exterior stairs or stairwells for entrances below finished grade along a wall facing a public road;

5. The property must be able to accommodate an additional parking space;

6. Secondary dwelling units in accessory buildings on Rural, Agricultural and Rural Shoreline Zones cannot exceed 45% of the gross floor area of the primary dwelling and must be located no more than 30 metres from the main house at their closest;

7. Secondary dwelling units in accessory buildings cannot be in the form of a mobile home dwelling in all Residential, Commercial and Future Development Zones;

8. Secondary dwelling units in accessory buildings may be in the form of a mobile home dwelling in Rural, Agricultural and Rural Shoreline Zones;

9. On lots in residential zones that do not abut a shoreline, accessory buildings or structures containing a secondary dwelling unit shall only be permitted in a rear or interior yard;

10.The secondary dwelling unit must be registered as stated in the “Registration of Secondary Units” By-law 2017-14 4

3. b) When am I not allowed a Secondary Dwelling Unit? Secondary dwelling units are not permitted:

1) Within a dwelling that is deemed to be a permitted use in Section 4.16 of CGS Zoning By-law 2010-100Z;

2) Within a dwelling located in an Environmental Protection (EP) Zone;

3) Within a dwelling that is permitted accessory to a permitted nonresidential use in Section 4.40.2 of CGS Zoning By-law 2010-100Z;

4) On a lot containing a garden suite; or

5) Within a building or structure accessory to 1), 2) or 3) above.

3. c) What Is Legal Non-Conforming Status and how is it obtained? Legal non-conforming status applies to use that was legally established prior to the passage of a zoning by-law which no longer provides that use. In order to apply for legal non-conforming status, a lawyer must send a letter requesting that the dwelling be reviewed for legal non-conforming status, provide evidence to prove that the second unit has continued to be in existence prior to any zoning by-law being in place and provide the required fee. Once a request for legal non-conforming status has been submitted, an investigation of all City of Greater Sudbury records and any other available records will be assessed to determine if the legal non-conforming status will be granted by the Chief Building Official. If a legal non-conforming status is granted, the owner will need to contact the City of Greater Sudbury Fire Prevention Services to request a fire retrofit inspection and pay the required fee. Fire safety requirements for an existing secondary unit are found in the Ontario Fire Code, Section 9.8 “Two Unit Residential Occupancies”. Further upgrading may be required and a building permit may be required to start that work. If a legal non-conforming status is not granted, the owner will be required to obtain a building permit and follow the requirements in Section 5.

SECTION 4: How Do I Legalize A Secondary Dwelling Unit 4.

a) For new secondary units created after July 12, 2016:

i. Confirm that the proposed secondary unit is permitted in Zoning By-law 2010-100Z.

4. b) For secondary units created prior to July 12, 2016:
