Markham is one of York Region's most dynamic municipalities, combining established suburban communities like Unionville and Markham Village with high-growth new development areas in Cornell, Wismer, and Greensborough. The city's significant technology and commercial sector adds a substantial commercial HVAC design component alongside residential work.
Building permits in Markham are issued by the City of Markham Building Standards Department. Our stamped mechanical drawing packages — CSA F280 calculations, duct layout, HRV design, and Schedule 1 documentation — are formatted to their requirements.
Markham's design outdoor temperature for CSA F280 heat loss is approximately -19°C to -21°C. New construction in Cornell and Wismer generates steady demand for standard residential mechanical packages. The Unionville and Old Markham Village areas generate renovation and addition work requiring mechanical updates to existing homes.
Markham's technology corridor along Highway 7 and the corporate campus areas of Buttonville and Markham Centre include significant commercial HVAC design opportunities. We serve medical offices, dental clinics, tech office fit-outs, and retail spaces throughout Markham with ASHRAE 62.1-compliant mechanical designs.
