What is the code minimum ceiling height of a Tiny House?

Monday, June 7, 2021

Habitable space and hallways of a Tiny House must have a minimum ceiling height of 6 feet 8 inches, per International Residential Code (IRC AQ103.1). Bathrooms, toilet rooms and kitchens can go as low as 6 feet 4 inches, but any obstructions, such as beams, ducts, or lighting, should not extend below these minimums.

    Lofts are exempted from these requirements. They must have a minium floor area of 35 square feet, and portions of a loft with a sloped ceiling height below 3 feet do not count towards the minimum floor area (IRC AQ104.1.3). But one exception is allowed: when under a gable roof with a minimum 6/12 slope, the minimum height to be counted towards floor area is lowered to 16 inches.
