Frequently Asked Questions

What are the parking spot constraints for a legal basement in Ancaster?

Under Hamilton Zoning By-law 05-200 (amended by By-law 22-132), zero additional parking spaces are required for a legal secondary suite in Ancaster. The property only needs to sustain the original parking spaces required for the primary residence.

What structural height restrictions apply to legal basement ceilings in Ancaster?

Under OBC Article 9.5.3.1, a secondary suite requires a continuous finished ceiling height of 1.95 meters (6'5"). Localized obstructions like heating ducts or structural beams are permitted to drop down to an absolute minimum headroom limit of 1.85 meters (6'1").

Can an Ancaster basement suite share the existing furnace and ductwork?

Yes. The Ontario Building Code permits a shared duct system only if it is outfitted with duct smoke detectors designed to instantly shut down the furnace fan upon smoke activation, preventing toxic migration. Alternatively, independent ductless mini-splits can be installed.
