Plex & multi-unit management in Richmond Hill.
Richmond Hill's multi-unit houses range from 1950s bungalows on wide Richvale lots to large 1990s homes in Bayview Hill and Oak Ridges with finished basements. The City permits additional residential units subject to zoning and a building permit, and it now offers a pre-approved detached ARU model for garden suites. We manage the main house and the suite as one rental property with one monthly statement.

Richmond Hill, specifically.
Plex & multi-unit management in Richmond Hill: the local picture
The best lots for extra units are in Richvale, west of Yonge, and Crosby, east of it, where postwar bungalows sit on deep parcels. Mill Pond and the old village core near Yonge and Major Mackenzie have older houses that call for careful, heritage-aware work. Bayview Hill, Westbrook and Jefferson add newer detached houses with large basements, while Oak Ridges, north of Bloomington, has suites tucked into houses near Lake Wilcox. Tenants include Mackenzie Richmond Hill Hospital staff, commuters on the VIVA Blue line along Yonge and on the Richmond Hill GO line, and workers at the offices around Highway 7 and Leslie.
Richmond Hill permits additional residential units in zones that allow detached, semi-detached and townhouse dwellings, under section 3.18 of its Comprehensive Zoning By-law, and a suite is legal only with a building permit. Ontario's rules let most urban residential lots carry three units in all. For a garden suite, the City's pre-approved detached ARU model can shorten the permit process, though site, servicing and conservation authority approvals still apply on lots near ravines. Inside the house, the Fire Code expects interconnected smoke alarms and a fire separation between suites, and we keep both serviced and documented.

- Consolidated reporting. Every unit on one statement, with per-unit ledgers.
- Capital planning. Roof, windows, boiler — budgeted before they become emergencies.
Is my Richmond Hill basement apartment legal?
Only if it has a building permit and meets the zoning rules for additional residential units. Many suites were finished without one. We can review the property history, arrange a fire safety check and help you decide whether to legalize before we lease the unit.
Does Richmond Hill have pre-approved garden suite plans?
Yes: the City offers a pre-approved detached additional residential unit model, submitted with a declaration form, which can speed up the building permit. Your lot must still meet zoning, servicing and any conservation authority requirements, so treat it as a starting point rather than a guarantee.
