Old Aurora lots routinely run 200 ft deep - the longest average rear-yard depth of any town in York Region. That depth is why Aurora is one of the few GTA municipalities where a two-storey garden suite with its own private yard still clears the angular plane without a minor variance. Aurora permits additional dwelling units with the Aurora Village and Northeast Old Aurora heritage districts adding design review in the core.
Large mature lots in Old Aurora with 200 ft depths, and Oak Ridges Moraine constraints on the western edge.
Aging-in-place design plans for a body that will change: blocking in the walls for future grab bars, a bathroom sized for assistance today, and a single-storey layout so the unit never depends on stairs. Single-storey means a wider footprint, so on a Aurora lot we test the plan against lot coverage and rear-yard soft landscaping before committing to the layout. Proximity is the point - the unit sits on the same parcel as family, so -5.1°C winters never mean a drive across Aurora to check in.

Almost always. A single-storey plan removes the stair as a future failure point, and the cost is a wider footprint that has to clear Aurora lot coverage. Where coverage is tight, a two-storey unit with a fully self-contained ground floor is the usual compromise.
