What records explain accessory dwelling units at a Fort Erie home?

Section 6.43 of Zoning By-law 129-90 permits, in a residential zone inside the urban boundary with full municipal water and sanitary sewer service, up to two accessory dwelling units in a single-detached, semi-detached or rowhouse/townhouse dwelling beside the main unit, or one inside the house and one detached accessory dwelling unit on the lot. Each accessory unit may take up to 40% of the main dwelling's floor area or 100 square metres, whichever is less, or the whole basement, and needs one parking space on the lot, with tandem parking allowed. A detached unit in a new accessory building has its own limits: 15% lot coverage, a rear or interior side yard, and a height of no more than the main dwelling's or 8 metres.

The Town says its zoning by-law is under review, together with a new Community Planning Permit System, so the section can change. 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.
