Frequently Asked Questions

What are the Town of Milton's parking rules for secondary suites?

Milton’s zoning bylaws stipulate that a property containing a legal second dwelling unit must provide a minimum of 1 dedicated, off-street parking space designated solely for the basement tenant. This parking space must be configurationally viable alongside the primary residence's required parking spaces and cannot violate front-yard landscaping or municipal right-of-way restrictions.

How is fire safety and sound isolation separation handled between floors?

To achieve compliance with the Ontario Building Code, a physical fire separation must be constructed between the upper and lower units. We install continuous Type X fire-rated drywall over resilient channels on the ceiling cavity, pack the joist spaces tightly with mineral wool sound/fire insulation, and deploy hardwired, interconnected smoke and carbon monoxide detectors.

Can a Milton basement suite share the existing furnace and ductwork?

Yes, provided an engineered mitigation strategy is implemented. The Ontario Building Code permits a shared duct system only if it is outfitted with duct smoke detectors and automatic fire dampers engineered to close instantly upon smoke detection, preventing toxic migration. Alternatively, we regularly install independent ductless mini-split units for complete zonal efficiency.
