The maximum lot coverage for all buildings in each zone shall be as specified on the attached Schedule of Zone Requirements.[1] Coverage of any lot by principal and accessory buildings shall be limited such that the ratio of the combined building footprint area compared with the area of the lot shall not exceed the established for the zone.

In the Commercial Recreation 40 (CR-40) Zone, tennis courts or swimming pool facilities, which are covered with temporary structures for seasonal use or play for no more than seven months each year, shall be considered at a ratio of 50% in determining building coverage.

The minimum yard depths in each zone shall be as specified on the attached Schedule of Zone Requirements.

Every part of a required yard shall be open and unobstructed from the ground upward except as follows:

All yards facing on a public street shall be considered front yards and shall conform to the minimum front yard requirements for the zone in which the property is located. For residential through lots, the area of the lot generally considered and designated the rear yard for accessory use and appurtenant accessory structures shall be considered the rear yard for zoning and land use purposes, except that the front yard setback for the applicable zone shall be maintained for all structures, including fences, along the associated right-of-way. No driveway access shall be permitted and no driveway shall be constructed within this yard area.

Sight triangles shall be maintained to provide adequate visibility for vehicular and pedestrian traffic. Sight triangles shall be kept free of visual obstructions which might otherwise be established, constructed, placed or allowed to grow within this area. Obstructions to vision shall include hedges, fences, walls, parking spaces or driveways and other objects except essential street appurtenances such as traffic safety or control signs and devices, utility poles or shade trees which are either less than one foot in caliper or which have had all limbs below eight feet removed.

Sight triangles at street intersections. An area of unobstructed sight shall be maintained within a triangular area at the intersection of two or more streets extending from a plane 18 inches above curb level to a plane 10 feet above curb level. The triangle shall be formed by the two intersecting street lines bounding the lot, or the projection of such lines, and by a line connecting points on each street line located 25 feet from the intersection of the street lines.

Sight triangles at side lot lines. An area of unobstructed sight shall be maintained within a triangular area at the intersection of any side lot line and any street line extending from a plane 30 inches above curb level to a plane eight feet above curb level. The triangle shall be formed by the intersecting street line and side lot line and by a line connecting points on each line located six feet from the intersection of the lines.

Sight triangles at other locations. Sight triangles may be required on any site plan or subdivision plat in such locations and at such dimensions as are specified by the design standards for such development.

No sign, nor any part of a sign, shall obstruct a sight triangle.

The maximum height of any building or structure in each zone shall be as specified on the attached Schedule of Zone Requirements.

The height limitations created hereunder for all uses other than single- or two-family residences may be exceeded by: not more than four feet by architectural appurtenances and enhancements such as pediments, parapets, walls, turrets or cornices; not more than six feet by rooftop equipment such as skylights, heating and air-conditioning equipment and ventilators; not more than 10 feet by chimneys, stair or elevator towers, or noncommercial radio and television antennas or lightning rods; and further provided that the cumulative total of such facilities shall not cover more than 15% of the building roof area. Architectural appurtenances such as spires, belfries, cupolas, domes or similar structures shall be permitted to exceed the height limitations herein by not more than 10 feet only if they are located on nonresidential buildings and are proven to the satisfaction of the Board (or Land Use Officer, if not part of a development application) to be the minimum height necessary to serve the purpose for which they are constructed. On principal single- and two-family structures, the permitted height may be exceeded by up to 10 feet by chimneys or lightning rods if they are proven to the satisfaction of the Land Use Officer to be the minimum height necessary to serve the purpose for which they are constructed.

The height limitations created hereunder shall apply to chimneys, ventilators, skylights, tanks, stair towers, elevator towers, appurtenances usually carried above the antennae attached to a building, except that the same may exceed said height limitations by not more than 15 feet except that skylights, heating and air-conditioning equipment and ventilators may exceed the height limitation by no more than 10 feet. Such features shall not exceed, in total coverage, 10% of the total roof area. In single-family residential zones and on properties adjacent to single-family residential zones any such appurtenances which exceed the height limit by more than five feet shall not be located nearer to any property line than a distance equal to its height above ground.

Freestanding accessories. Water towers, noncommercial radio and television antennae and flag poles which are erected as freestanding accessories and which might normally exceed the height limitations established by this chapter may be erected to a height which can be demonstrated to the satisfaction of the Land Use Officer as necessary to accomplish their intended function, except that in residential zones and on properties adjacent to residential zones, no such structure may be located nearer to any property line than a distance equal to its height above ground.

Signs or display. No sign, nameplate, display or advertising device of any kind whatsoever shall be inscribed upon or attached to any chimney, tower, tank or any other structure which extends above the height limitations established in this chapter.

Barns on farms. On farms only, barns may be erected to a height which can be demonstrated to the satisfaction of the Land Use Officer as necessary to accomplish their intended function, except that no such barn shall exceed 35 feet in height.

Barn setback requirements. In residential zones and on property adjacent to residential zones, no barns may be located nearer to any property line than a distance equal to its height above ground.

In the Commercial Recreation 40 (CR-40) Zone, one field house type structure, up to 20,000 square feet in size, may be erected to a height not to exceed 46 feet, provided a setback of a minimum of 500 feet from any property zoned for residential use is maintained.

In the OR-2, OR-5 and OR-10 Zones, the maximum permitted building height may be increased to a maximum of four stories and 80 feet, provided that the following criteria are met:
