Basement Suites in Aurora - Design, Permits, Construction

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. North-GTA snowfall of 148 cm and -5.1°C winters give Aurora a May-October working season - foundations for basement suites go in before the ground closes, with interior finishing carried through the cold months.

A basement suite lives or dies on two measurements taken inside the existing Aurora house: finished ceiling height under the joists, and whether a code-compliant egress window can be cut without undermining the foundation wall. Where the head height is short, we underpin or bench the footing - a wet-trades sequence that runs year-round indoors, which is why basement work is the form we schedule outside the May-October window. Fire separation between the two dwellings, an independent exit, and interconnected alarms are the three items that most often turn an existing finished basement into a non-compliant one.
