A. Floor Area Ratio Calculations: The following shall be included in the calculation of floor area for the purposes of determining floor area ratio in residential zoning districts:
1. All gross square footage of each floor above grade. A maximum of sixty four (64) total square feet shall be excluded from this computation for balconies or similar projections that are four feet (4') deep or less.
2. Roofed porches, including areas with open roof trellises.
3. Open porches, across all or part of the elevation of a house facing a street, that are greater than eight feet (8') deep.
4. Garages, sheds and gazebos, whether permanently fixed to the ground or freestanding.
5. That gross square footage of a basement with a ceiling in excess of three feet six inches (3'6") above grade.
6. Those portions of house attics, finished or unfinished, that have a clearance equal to or greater than seven feet (7') in height, even if the space is interrupted with crossties or has a truss design.
7. Open wood decks if the floor is more than three feet six inches (3'6") above grade.
8. Sun or other decks with rails higher than three feet six inches (3'6") on any floor of the house.
9. Open courtyards surrounded eighty five percent (85%) or more by perimeter walls.
10. The square footage of interior stairwells for each floor on which they are located.
11. Those portions of cathedral ceilings that are fourteen feet (14') or more in height shall be counted as two (2) stories.
B. Floor Area Ratio Guidelines; Review And Approval:
1. A completed floor area ratio worksheet is required for each lot on which a new building or structure is proposed or on which modifications are proposed to an existing building or structure (i.e., additions) that would increase the floor area from that which presently exists.
2. Copies of plats of survey, building plans and other drawings as necessary to demonstrate the basis of computations must accompany the completed floor area ratio worksheet. Additional support documentation shall be submitted as required by the Village to complete the review.
3. Worksheets prepared in conjunction with the construction of a new residential home or addition, etc., must be certified by an engineer or architect. Worksheets for other applications do not require certification.
4. All completed worksheets and support documentation must be submitted to the Village with a building permit application.
5. Upon receiving a completed worksheet with all necessary support documentation, the Building Commissioner, or appointed designee, shall, within two (2) weeks, determine whether the proposed improvements comply with the applicable floor area ratio requirement.
