Overview
The rough-in inspection for the heating system, distinct from Markham's heating final information sheet for the same trade at completion: it is often conducted to coincide with the framing and plumbing rough-in inspections, before insulation goes in. It confirms the system is sized and installed to meet heating and ventilation needs for a healthy living environment. A provincially qualified building inspector reviews the supply air system, return air system, exhaust systems and mechanical ventilation, matched by a reverse-side deficiency checklist.
