What the record shows
The table in section 16.13 of Zoning By-law 2024-100 permits up to three accessory dwelling units with a one-unit dwelling connected to full municipal services in a residential zone, one with a one-unit dwelling on private or partial services or in a non-residential zone, two with a two-unit dwelling and one with a three-unit dwelling; each unit has at most two bedrooms and 100 square metres, with limits tied to the main home's floor area that don't apply to a unit entirely in a basement. Only one detached accessory building on a lot may hold units, it may be no more than 45 metres from the main dwelling, the units can't be severed, and no unit may sit in an area subject to natural hazards such as wetlands, erosion hazards or flooding as defined in flood plain studies and the Bay of Quinte Lake Ontario Shoreline Management Plan. The City's page summarises this as up to three units on a property in the urban area.
The City's page says a unit becomes legal and registered once a building permit has been issued, the required inspections are passed and a final inspection and occupancy permit are issued, and that registered units are listed in the City's Accessory Dwelling Unit Registry, updated monthly; only registered units are considered legal. A permission in the zone does not make an existing basement apartment lawful; the permit and registry records are where that is answered.
