Guest and Visitor 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.

A guest suite is used intermittently, which changes the mechanical design rather than the structure: the unit has to hold heat at -5.1°C while empty without running a full system, so setback controls and freeze protection matter more than capacity. We still build and permit it as a full dwelling in Aurora - kitchen, bath, separate entry - because a unit permitted as habitable space keeps every future option, including renting it. Plumbing runs are detailed for seasonal shut-off and drain-down, an item that generic ADU drawings almost never include and that a 148 cm snow climate makes non-optional.
