What records explain additional dwelling units at a Clarington home?

Section 3.2 of Zoning By-law 84-63 permits additional dwelling units within any legally permitted single detached, semi-detached or townhouse dwelling and within an accessory building on the same lot, for a maximum of three dwelling units on a lot. None is permitted in the Environmental Protection Zone, and in the Greenbelt's Protected Countryside they are permitted only in single detached dwellings or accessory buildings that existed on July 1, 2017. The Municipality's page says two units may be permitted, one in the house and one in an accessory building, in Courtice, Bowmanville, Newcastle, Orono, the hamlets outside the Oak Ridges Moraine and the 'white belt'; one in parts of the moraine and the Greenbelt; and none on Natural Core and Natural Linkage lands, floodplains or Environmental Protection zones.

The house must have two parking spaces and each additional unit one more, and a unit in an accessory building has its own limits on floor area, setbacks, lot coverage and height, 5.25 metres in Urban Residential zones. Section 3.2 says additional dwelling units must be registered with the Municipality, and its page says a unit is considered registered once the building inspector grants occupancy; a unit from before July 14, 1994 needs a Fire Code inspection. A general permission does not make an existing basement apartment lawful; registration, the building permit and inspections are the records that do.

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