Open Area Calculation
|
|
Note: The above sketch is illustrative only.
|
|
How to figure:
|
|
Step 1. Calculate Open Area
|
|
|
Lot area minus house footprint including porches,
decks, steps and bulkheads
|
|
|
|
Minus accessory building(s) footprint
|
|
|
|
Minus ponds and horizontal areas subject to
oceanic tidal action and areas below mean high water.
|
|
Step 2. Calculate Gross Floor Area
|
|
|
Sum of all floors including basement, cellar,
porches and accessory buildings
|
|
|
|
Excludes crawl space, attic space, and space
under a roof each of which is less than five feet in height
|
|
Step 3. Compare Open Area to Gross Floor Area
|
|
|
Depending on the zone of the property there
are two situations:
|
|
|
|
1.
|
Nearly all properties require one square foot
of open area for each one square foot of gross floor area;
|
|
|
|
2.
|
Only in the Business 1 Zone District and for
nonresidential uses in the Business Residential District is there
the requirement of one square foot of open area for each two square
feet of gross floor area.

B. Interpretation of dimensional regulations.
(1) The minimum front yard setback shall be determined
by a line parallel to the front lot line extending from one side lot
line to the other. In the case of corner lots, the front setback line
shall be observed for all bordering streets. Exterior steps and landings
not exceeding the minimum required egress width and depth and not
exceeding four feet in height as set forth in the State Building Code
may protrude into the minimum front setback area. No part of any building
shall be placed within or protrude into any of the setback areas except
for the following: steps only in the front yard setback as described
in this subsection and in all setback areas; cornices not exceeding
18 inches in width, eaves, chimneys, windowsills, signs, fences. Any
projection other than the foregoing exceptions requires a special
permit for use and dimension from the Board of Appeals. (See illustrative
sketch.)
(2) Open area as listed in Table 2 specifically excludes
those portions of a lot devoted to house footprint including porches,
decks (unless cantilevered), steps and bulkheads, accessory building(s)
footprint, ponds and horizontal area subject to oceanic tidal action
and areas below mean high water.
(3) Not more than one principal dwelling or other principal building shall be constructed or placed on a lot except as expressly set forth in §
200-11B(2) herein.
