Basement Ventilation/ air flow


I just finished my basement and on the final inspecion the building inspector asked about fresh air/ oxygen flow in the basement. The finished are in my basement is completely below grade and has no windows. I did install a "sani dry" system that removes humidity and circulates clean air. Is this enough or do I need to allow "new, fresh" air to come in some way.

Probably not. If the inspector is stating that you need combustion air for the hvac & water heater, your choice is either get direct vent high efficiency, or change over to electric.

This is the first time I have ever heard of a finished basement without egress windows approved by an Inspector. Or are there no bedrooms and one exterior (egress) door?

Where are you located?

Just finished a walk out basement. As I recall, you need a minimum amount of ventilation (fresh air, measured in sq ft of open glass or doorway). Its a percentage of habitable space, though for the life of me I dont remember what it was.

May have something to do with fire.

GBR...must be a ventilation section in the code book.
