In-Law and Multigenerational Suites in Aurora: local conditions
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.
In-Law and Multigenerational Suites on a Aurora lot: what's involved
An in-law suite is a second dwelling for family, and the building department reviews it exactly as it reviews a rental: separate entry, fire separation, interconnected alarms and the Aurora egress requirement apply regardless of who lives there. Where it is carved out of the existing house, the sequence is interior and weather-independent; where it is detached, it follows the May-October season like any new build. Sound separation is the item families care about most and codes address least - we detail resilient channel and insulated party assemblies beyond the minimum rating.

Yes. A self-contained second dwelling in Aurora needs an exit that does not pass through the primary unit, along with rated fire separation and interconnected alarms. The requirement is about the dwelling, not the relationship - a suite for family is reviewed identically to a rental.
