In general, from a developer's standpoint the height of each floor follows the below rule of thumb. This is a generalization and sometimes you have different heights - for example Third + Shoal's top floors are double height so that they can have mezzanine floors added if the tenant wants that.
Deck-to-deck means the physical measurement between the ceiling (bottom of the upper floor) to the floor (top of the lower floor). You also have to account for about 6-8 inches of concrete - depending on the floor load - on each floor to get the actual height.
And again, these are
generalizations:
Parking garage floors - 8.5 to 11 feet deck-to-deck (you want a minimum 7-foot clear, taking into consideration the beams and the fire sprinklers) Shorter floors mean more parking.
Residential floors - 9.5 to 12 feet deck-to-deck
Office floors - 12 to 14 feet feet deck-to-deck
The reason office floors have a higher deck-to-deck height is because of all the stuff that has to go in the ceiling. From A/C to cabling to fire sprinkler systems to whatever. A/C vents in residential buildings are much smaller & thinner.
