A. 
A use, building or structure lawfully in existence as of the effective date of this chapter and nonconforming with it or any subsequent amendment may be continued, except as otherwise provided herein with respect to specific uses. Upon request, the Building Inspector may issue certificates of nonconformance to owners or operators of bona fide nonconforming uses, buildings or structures who desire confirmation of their rights hereunder.
B. 
It is the purpose of this article to limit the injurious impact of nonconforming uses, buildings, lots and structures on other adjacent properties within a particular district and the community as a whole, while recognizing that alterations, continuations and extensions of nonconforming uses, buildings or structures may not be contrary to the public interest or the general purpose of this chapter, when failure to allow such alteration, continuation or extension would itself lead to neighborhood or district deterioration.
C. 
It is further the purpose of this article to set forth those standards which are to be applied by the Town in determining the reasonableness of proposals to alter, continue or extend a nonconforming use and to establish when Town review and approval shall be required for such actions.
D. 
The protections extended by this article to existing nonconforming uses, buildings, lots or structures, commonly known as "grandfathering," shall not extend to any nonconforming activity occurring subsequent to the effective date of this chapter, as amended.
A. 
Normal maintenance and repair activities, such as painting, replacing a roof or fixing gutters, shall be permitted. Also permitted are alterations, such as adding or removing windows, and interior renovations that do not structurally alter buildings, add living areas or result in extended or increased nonconforming use of a building, lot or structure.
B. 
Increases in outside storage or display of retail or wholesale inventory, which in the ordinary course of business would be sold within one year, shall be permitted, provided they do not eliminate parking spaces, unoccupied open spaces or accesses required by this chapter. Notwithstanding this provision, however, the Planning Board, in reviewing any special use application for expension or upon determining, with respect to any present use, that a condition exists which requires remedies, may establish limits on such storage or display or require removal of inventory (altogether or to another location on the site) to preserve adequate sight distances and residential buffers or otherwise protect public health, safety and welfare.
A. 
If any nonconforming use, building or structure is damaged, it may be restored or reconstructed by building permit issued within five years of the date of the damage.
B. 
A nonconforming use, building or structure may be reestablished within a period of five years after it has been discontinued or vacated.
C. 
A nonconforming use, building or structure may be considered abandoned under any one of the following circumstances:
(1) 
The intent of the owner to discontinue the use is made obvious by the posting of signs, boarding up of windows, failure to pay taxes or assessments or other measures that demonstrate the enterprise is going out of business or the use is otherwise ending; or
(2) 
The building has not been occupied for five years or more and/or the use has not been exercised; or
(3) 
The nonconforming use has been replaced by a conforming use or changed to another use under permit from the Town.
D. 
The Town Planning Board may, subject to site plan review, permit the reestablishment of an abandoned use where the structure is particularly suited to such use and difficult to adapt to other conforming uses, provided the use has not been abandoned for more than five years. The Town Board may extend this period for good cause but not more than an additional five years by other than a zoning amendment.
E. 
The Building Inspector, on determining these circumstances exist, shall, by certified mail, so notify the property owner of record, informing the owner the use is considered abandoned and may not be reestablished once a period of 12 additional months has expired. If an owner cannot be reached through the mail, the Building Inspector shall publish the notice once in a newspaper of general circulation in the Town and/or post the property and the owner shall be presumed to have been notified.
Excepting for activities provided for above, single- and two-family residential uses and accessory uses, all changes, additions, and expansions to nonconforming uses shall be considered special uses. No change, addition, or expansion shall result in a more intensive category of use. A nonconforming retail enteprise could be converted to a barber shop, for example, but not to an industrial use. Permits for changes, additions, or expansions shall be granted only after a determination by the Planning Board that the following conditions have been, or will be, satisfied.
A. 
There shall be no expansion in the amount of land area outside a nonconforming facility (outdoor area) used for storage of materials, supplies and/or products, except as provided herein.
B. 
Where the nonconforming activity is one which necessarily results in the storage of large quantities of material, supplies or products outside (such as a lumberyard), the Planning Board may require dense evergreen screening sufficient to shield all such materials from the view of adjacent landowners and/or the traveling public.
C. 
No addition, change or expansion of a nonconforming use shall further violate setback and/or height regulations of the district in which it is located; however, a nonconforming single- or two-family residential use shall be granted an exception from this requirement upon receipt of an area variance from the Zoning Board of Appeals.
D. 
There shall be no increase in the amount of stormwater runoff for the site over what was existing as of the date of the enactment of this chapter. A professional engineer or other appropriate professional may be relied upon to recommend appropriate measures to control stormwater runoff. Such measures shall be attached as conditions of approval by the Planning Board.
E. 
In no case will a change, addition or extension of a nonconforming use be allowed that would result in a traffic increase that would decrease the level of service for the highway, the diversion of traffic closer to a nearby residence or a reduction of any of the parking and unloading requirements of this chapter where additional parking or loading would otherwise be required due to the change, addition or expansion. If the total number of parking spaces for the site is to be increased more than 25% over those available as of the date of this chapter, the Planning Board may require vegetative screening of the parking area from nearby residential areas.
F. 
The use may only be expanded or extended onto another property of record if that property is immediately adjacent to the lot on which the original structure or use was located as of the effective date of this chapter or amendments hereto and the use is not one which has been altogether prohibited as a new use under this chapter.
G. 
Should the use proposed for expansion or extension be one which is specifically prohibited as a new use in the Town or is determined by the Planning Board to be one similar to such a use or of such a nature as to impose health, safety or welfare concerns which cannot be satisfied by the imposition of the conditions permitted under this chapter, the requested expansion or extension shall be denied.
A structure may be erected on any lot of record, existing at the time this chapter is enacted; provided no front yard is reduced in size and no side yard is reduced to less than 50% of the requirement for the district in which it is located or 20 feet, whichever is greater; and a sewage disposal system meeting New York State standards, including well and septic isolation distances, can be placed on the lot should public facilities be unavailable.
