What records explain additional residential units at an Orangeville home?

Section 5.29 permits attached additional residential units in a detached, semi-detached, linked or townhouse dwelling, and detached units in an accessory building on the same lot as one of them: at most two attached units, or one attached and one detached, for three dwelling units in all. Each unit may have at most two bedrooms and needs one parking space beyond the home's own, at least 2.6 metres wide, and a 1.2-metre unobstructed path from the street or lane to its entrance. A detached unit is limited to 4.3 metres in height, or 6.1 metres above a private garage, and never taller than the main dwelling, with lot coverage of 45% and at least 4 metres from the main dwelling.

The Town's guide says every additional unit must be connected to municipal water and sewer through the main dwelling and needs a building permit, and that Town staff can verify whether an existing unit was established in compliance with by-law and code requirements. A general permission does not make an existing basement apartment lawful; the building permit and inspections are the records that do.

Extra units allowed is in the free check as a summary of the Town's rule, from our hand-kept table of city rules, and the full report reads the lot's zone where the Town's zoning map is open data we can use; where it isn't, the report's line says where the Town publishes it. Neither is confirmation that a particular unit holds a permit or may be occupied.
