- B1/3 of the area of that floorCorrect
- C1/4 of the area of that floor
- D1/5 of the area of that floor
Solution
Concept
Maximum area limit for mezzanine floor
Formula
NONE
Step-by-step solution
1. A mezzanine floor is an intermediate floor constructed between the main floors of a building. 2. Building regulations restrict its area so it does not count as a full structural story. 3. Standard bylaws restrict the maximum area of a mezzanine floor to 1/3 of the area of that floor. Answer: B
Explanation
A mezzanine is an intermediate floor constructed between the main floor and ceiling of a building. To prevent it from being classified as a full story and affecting structural and safety limits, building bylaws restrict its area to a maximum of 1/3 of the main floor area below it. Hence, 1/3 is the standard limit for a mezzanine floor area.
Why the other options are wrong
A) 1/2 of the floor area exceeds permissible limits and would qualify the mezzanine as a full story. C) 1/4 of the floor area is overly restrictive compared to standard building bye-law limits. D) 1/5 of the floor area is significantly less than the allowed 33.33% limit for mezzanine floors.
Shortcut
Mezzanine floor area is restricted to a maximum of 1/3 of the main floor area.
Common mistake
Selecting 1/2 or 1/4 of the floor area due to variations in different municipal building bylaws.
Correct answer: B) 1/3 of the area of that floor
