Default Ceiling Heights in an unfinished basement

Single Detached home

Issue: Unfinished Basement height under beams and ducts

During frame walk in the basement I noticed that the HVAC ducts are below the beam, the height from the floor to the HVAC duct is below 6ft. When we finish the basement that height will reduce further to 5 ft or less. As a health and safety matter, the Ontario Building Code regulates a minimum ceiling height in the basement. From what I read in the building code, the minimum height under beams and ducts is 1950 mm (6.397638 Feet).

When I approached the builder with my observation, I was told that the minimum height does not apply to unfinished basement. Please help me with this issue.

Does the building code for ceiling Heights apply to unfinished basement ?
