Q: What is a Mechanical Deduction?
A: A Mechanical Deduction is a floor area deduction where the area used for Mechanical Equipment is subtracted from the Total Zoning Floor Area of a proposed building. When planning a building, Mechanical Deductions should be taken to ensure that the maximum Zoning Floor Area for a site is achieved. Mechanical Deductions should not exceed 2% of the area of the building. Mechanical Deductions may include Plumbing Shafts, Mechanical Equipment Rooms, and similar areas. Key Plans illustrating the location, dimension, and area of each Mechanical Deduction must be provided and tabulated to satisfy DOB requirements.
