The ceiling height affects a two-story house’s average height. A storey is often measured as 10 feet. A two-story house would be around 20 feet high given the assumption of 8-foot ceiling heights and a 2-foot allowance for the infrastructure of the roof.
Some homes naturally exceed 20 feet in height due to their higher ceilings. But figuring out stories isn’t always as easy as doubling the first floor of the house’s story height. The estimates are also impacted by the roof pitch and, if different from the first floor, the height of the second floor ceilings. However, some city laws restrict the height of two-story homes for aesthetic reasons.
