Plex & multi-unit management in Newmarket.
Newmarket has required registration of second units since 2013, so most legal suites in town have an 'N' plate by the door and a 'B' added to their address. The rental market is anchored by Southlake Regional Health Centre on Davis Drive and by GO and VIVA commuters. We manage registered additional residential units and the houses they sit in, with one statement per property.

Newmarket, specifically.
Plex & multi-unit management in Newmarket: the local picture
Old Newmarket, around Main Street South and the historic core near Fairy Lake, has Victorian and Edwardian houses, several long divided into suites. Gorham-College Manor and Bristol-London, built from the 1960s to the 1980s, have bungalows and back-splits with basements suited to second units. Glenway, Stonehaven and Summerhill Estates add larger 1980s to 2000s houses, and Woodland Hill and Copper Hills newer ones. Southlake Regional Health Centre is the dominant employer, and many of its staff rent close by. The VIVA rapidway on Davis Drive and Newmarket GO on the Barrie line carry most other tenants, along with York Region's head office staff.
Newmarket's By-law 2013-13, as amended, requires every house with an additional residential unit to register through a one-time application. Owners file documents from the fire department and the Electrical Safety Authority, or a final building permit inspection, and pay a one-time fee. Each ARU needs a private entrance, a kitchen, living and sleeping space and a bathroom. Provincial changes since 2022 allow most urban residential lots to carry up to three units. We keep the registration, ESA and fire records together and test alarms on a schedule, because a registered unit is only as good as its upkeep.

Is Newmarket a good market for a duplex?
Demand is steady, driven by Southlake, York Region offices and commuters on the Barrie GO line. Older bungalows near Davis Drive convert well. We do not promise returns, but we will price each suite from current comparables and show you realistic running costs before you buy.
