We think that this would be classified as an enclosed garage and require mechanical ventilation but the door is ~5% of the total SF and meets natural ventilation. There is also a 525 SF private garage bay with the same door as the above parking garage.

  3. Garage Ventilation R-2 Occupancy - The Building Code Forum

    Does IBC Section 1203.4.2 and IMC Section 401.6 require a mechanical exhaust system because of the exhaust fumes from the motor vehicles? The only "incorrect" statement above is relating to the garage doors. There are actually two garage doors for four stalls, not "Each stall is provided with a separate overhead door opening", as written.

    Our Ohio code for both residential and commercial is based on the 2009 ICC codes. I can solve the problem this time, I was just bringing up to this forum because I was totally surprised to see that 100 CFM of mechanical exhaust is now required in EVERY residential kitchen both in multi-family and single family.

    Re: Repair Garage Ventilation IMC section 502.14 also requires mechanical ventilation. Also I see the note "mechanical exhaust required" on table 403.3 as meaning just that--ventilation has to be by mechanical means, not natural. If natural ventilation were allowed in these occupancies, why the footnote saying mechanical exhaust required?
