The Town of Newmarket has initiated a Town-wide Official Plan Amendment and Zoning By-law Amendment to implement Provincial legislation and regulation changes regarding Additional Residential Units. 

Additional Residential Units are separate, self-contained dwelling units with a private entrance, cooking, sleeping, and sanitary facilities, provided for the exclusive use of those residing within the unit. An Additional Residential may be located within the primary dwelling (referred to as an Attached Additional Residential Unit) or within an accessory building or structure (referred to as a Detached Additional Residential Unit) on the same lot as the primary dwelling. 

The purpose of the Official Plan Amendment is to update the Town of Newmarket’s Official Plan policies to conform to current Provincial policy that allows up to three residential units as-of-right on parcels of land where single-detached, link, semi-detached, and townhouse dwellings are permitted. These units may be configured as follows: 

Up to one (1) primary dwelling unit and two (2) additional residential units within the primary building; or 

Up to one (1) primary dwelling unit and one (1) additional residential unit within the primary building and one (1) additional residential unit in a detached ancillary building on the same lot. 

The Zoning By-law Amendment proposes to amend Zoning By-laws 1979-50, 2010-40, and 2019-06 to implement general zone provisions to regulate Attached and Detached Additional Residential Units. Specific zone standards are also proposed to regulate the location, size, height, and access requirements for Detached Additional Residential Units.
