Final answer:
The minimum ceiling height for non-habitable basement spaces is typically 7 feet, as measured from the finished floor to the lowest point of the ceiling.
Step-by-step explanation:
The portion of the question you're asking about refers to the minimum ceiling height requirements for certain areas of a basement as specified in building codes. These codes vary by location, but a common standard for the minimum ceiling height in non-habitable spaces such as basements, hallways, bathrooms, toilet rooms, and laundry rooms is often 7 feet. This is typically measured from the finished floor to the lowest point of the ceiling (such as the bottom of ceiling beams).
