Separation or subdivision of a lot. Where a lot is formed hereafter from the part of a lot already occupied by a building, such separation or subdivision shall be effected so as not to violate any of the requirements of this chapter with respect to the existing building, including yards and other required spaces in connection therewith. No zoning permit shall be issued for the erection of a building on the new lot thus created unless there is full compliance with all the provisions of this chapter and Chapter 204, Subdivision of Land, of this Code.
D. 
Irregularly shaped lots. Where a question exists as to the proper application of any of the requirements of this chapter to a particular lot or parcel because of the peculiar or irregular shape of the lot or parcel, the matter shall be referred to the Zoning Board of Appeals and dealt with in accordance with the applicable provisions of § 235-62.

Before a fence (other than a temporary one) shall be erected, a zoning permit must be obtained from the Building Inspector. A request for a permit shall be accompanied by a site plan which shall show the height and location of the fence in relation to all other structures and buildings and in relation to all streets, lot property lines and yards. These restrictions shall not be applied so as to require a permit for, nor restrict, the erection, alteration, or reconstruction of fences for agricultural uses on farms or temporary fences (i.e., snow fences, garden fences, etc.), provided such temporary fences shall not exceed four feet in height, shall be at least 50% open construction and shall not pose a hazard to persons or traffic circulation. A temporary fence shall be removed once it is no longer being used or is necessary for its intended purpose.

(3) 
Fences may be erected, altered or reconstructed to a height not to exceed eight feet above ground level when located more than 20 feet from the street right-of-way line.
(4) 
These restrictions shall not be applied so as to restrict the erection of a wall for the purpose of retaining earth.

Fencing used to enclose a tennis court may be permitted up to 10 feet in height provided that such fencing is not closer than 25 feet to a side or rear property line.
(6) 
No fence shall be erected in a special flood hazard area, except for fences connected with an agricultural use when it can be demonstrated that such fence would not restrict the flow of floodwaters nor have an adverse impact on any buildings.
(7) 
The finished side of the fence shall face the adjoining properties.
B. 
Commercial and industrial fences shall be reviewed and approved by the Planning Board as part of the site plan approval process.
Where in any district a commercial or industrial use is created adjacent to an existing residential use, a buffer strip shall be established by the nonresidential use along the lot line adjacent to the residential use.
Outside solid-fuel-burning devices shall not be installed in an R District or within 500 feet of such district. When installed outside the R District (and the required five-hundred-foot buffer), such units shall be installed and operated in a manner as will not allow smoke or fumes to enter buildings on surrounding properties.
