Published by Town of Whitchurch-Stouffville under Second Suite Permits
A clause-by-clause comparison the Town of Whitchurch-Stouffville publishes for second-suite design, setting the Ontario Building Code's Part 9 requirements for houses existing less than five years against the relaxed Part 11 provisions for houses existing more than five years, covering room heights and areas, door and window dimensions, stairs and guards, fire separations, smoke alarms, ventilation and heating equipment. It is one of three second-suite guides the Town posts alongside its second-suite step guide and Q&A guide, and its 400-square-foot minimum suite size echoes the Town's comprehensive zoning by-law.
