A. 
Within the districts established by this chapter or amendments that may later be adopted, there exist lots, structures, uses of land and structures, and characteristics of use which were lawful before this chapter was passed or amended, but which would be prohibited, regulated, or restricted under the terms of this chapter or future amendment. It is the intent of this chapter to permit these nonconformities to continue until they are removed, but not to encourage their survival. It is further the intent of this chapter that nonconformities shall not be enlarged upon, expanded or extended, nor be used as grounds for adding other structures or uses prohibited elsewhere in the same district.
B. 
Nonconforming uses are declared by this chapter to be incompatible with permitted uses in the districts involved. A nonconforming use of a structure and land in combination shall not be extended or enlarged after passage of this chapter by attachment on a building or premises of additional signs intended to be seen from off the premises, or by the addition of other uses, of a nature which would be prohibited generally in the district involved.
C. 
To avoid undue hardship, nothing in this chapter shall be deemed to require a change in the plans, construction or designated use of any building on which actual construction was lawfully begun prior to the effective date of adoption or amendment of this chapter and upon which actual building construction has been carried on diligently. "Actual construction" is hereby defined to include the placing of construction materials in permanent position and fastened in a permanent location.
D. 
Where excavation or demolition or removal of an existing building has been substantially begun preparatory to rebuilding, such excavation or demolition or removal shall be deemed to be actual construction, provided that work shall be carried on diligently.
A. 
In any district in which single-family dwellings are permitted, a single-family dwelling and customary accessory buildings may be erected on any single lot of record at the effective date of adoption or amendment of this chapter, notwithstanding limitations imposed by other provisions of this chapter. Such lot must be in separate ownership and not of continuous frontage with other lots in the same ownership. This provision shall apply even though such lot fails to meet the requirements for area or width, or both, that are generally applicable in the district, provided that yard dimensions and requirements other than these applying to area or width, or both, of the lot shall conform to the regulations for the district in which such lot is located. Variances shall be obtained only through action of the Board of Adjustment.
B. 
If two or more lots or combinations of lots and portions of lots with continuous frontage in single ownership are not of record at the time of passage or amendment of this chapter, and if all or part of the lots do not meet the requirements established for lot width and area, the lands involved shall be considered to be an undivided parcel for the purposes of this chapter, and no portion of said parcel shall be used or sold in a manner which diminishes compliance with lot width and area requirements established by this chapter, nor shall any division of any parcel be made which creates a lot with width or area below the requirements stated in this chapter.
C. 
Any vacant lot existing at the effective date of adoption or amendment of this chapter whose area or dimensions do not meet the requirements of the district in which the lot is located may have a building permit issued for a use permitted for that zoning district without an appeal to the Board of Adjustment, provided the building coverage limit is not exceeded, parking requirements are met, and the yard and height provisions are reduced by the same percentage that the area of such lot bears to the zone district requirements, except that no side yard shall be less than half that required by this chapter or five feet, whichever is greater, and no building shall be required to have a height less than one story or 12 feet.
Where at time of passage of this chapter lawful use of land exists which would not be permitted by the regulations imposed by this chapter, and where such use involves an individual structure with a replacement cost exceeding $1,000, the use may be continued so long as it remains otherwise lawful, provided that:
A. 
No such nonconforming use shall be enlarged or increased, nor extended to occupy a greater area of land than was occupied at the effective date of adoption or amendment of this chapter;
B. 
No such nonconforming use shall be moved in whole or part to any portion of the lot or parcel other than that occupied by such use at the effective date of adoption or amendment of this chapter;
C. 
If any such nonconforming use of land ceases for any reason for a period of more than a year and a day, any subsequent use of such land shall conform to the regulations specified by this chapter for the district in which such land is located; and
D. 
No additional structure not conforming to the requirements of this chapter shall be erected in connection with such nonconforming use of land.
Where a lawful structure exists at the effective date of adoption or amendment of this chapter that could not be built under the terms of this chapter by reason of restrictions on area, lot coverage, height, yards, its location on the lot, or other requirements concerning the structure, such structure may be continued so long as it remains otherwise lawful, subject to the following provisions:
A. 
No such nonconforming structure may be enlarged or altered in any way which increases its nonconformity, but any structure or portion thereof may be altered to decrease its nonconformity;
B. 
Should such nonconforming structure or nonconforming portion of a structure be destroyed by any means to an extent of more than 50% of its replacement cost at time of destruction, it shall not be reconstructed except in conformity with the provisions of this chapter. Any remaining portion of the building or structure shall be removed from the premises without delay, and in any case, within 180 days of the date of the damage;
C. 
In the event that the cost of repair or replacement is 50% or less of the physical value, the building or structure may be repaired and used for the same purposes, provided that the original nonconformity is not exceeded, and repair or reconstruction is begun with 180 days of the date the building or structure was damaged. The new construction must comply with all new or revised ordinances other that the original noncompliance;
D. 
When a conforming or nonconforming building is destroyed by fire, explosion, or by any other cause, the debris from such building shall be removed from the premises within 30 days so that the same shall not remain as a nuisance thereon;
E. 
Should such structure be moved for any reason for any distance whatever, it shall thereafter conform to the regulations for the district in which it is located after it is moved;
F. 
Any existing lot on which a building or structure is located and which lot does not meet the minimum lot size, or a structure which does not meet all the yard requirements, may have additions to the principal building and/or construct an accessory building without an appeal to the Board of Adjustment, provided:
(1) 
The total permitted building coverage is not exceeded;
(2) 
The accessory building and/or any addition do not violate any other requirements of this chapter, such as but not limited to height, setback, and parking; and
G. 
If any such nonconforming use of land ceases for any reason for a period of more than a year and a day, any subsequent use of such land shall conform to the regulations specified by this chapter for the district in which such land is located.
If lawful use involving individual structures with a replacement cost of $1,000 or more, or of structure and premises in combination, exists at the effective date of adoption or amendment of this chapter, that would not be allowed in the district under the terms of this chapter, the lawful use may be continued so long as it remains otherwise lawful, subject to the following provisions:
A. 
No existing structure devoted to a use not permitted by this chapter in the district in which it is located shall be enlarged, extended, constructed, reconstructed, moved or structurally altered except in changing the use of the structure to a use permitted in the district in which it is located. However, within the C1-Commercial District, any commercial use and structure which existed and was permitted on May 13, 1992, but is now nonconforming may be extended or enlarged on one occasion during its permitted nonconformity, provided that the extension or enlargement does not exceed 50% of the gross floor area existing on May 13, 1992, and the extension or enlargement does not violate any other provisions of this chapter or other applicable town ordinances.
[Amended 3-10-2015 by Ord. No. 15-02]
B. 
Any nonconforming use may be extended throughout any parts of a building which were manifestly arranged or designed for such use at the time of adoption or amendment of this chapter, but no such use shall be extended to occupy any land outside such building;
C. 
If no structural alterations are made, any nonconforming use of a structure, or structure and premises, may as a special exception be changed to another nonconforming use, provided that the Board of Adjustment, either by general rule or by making findings in the specific case, shall find that the proposed use is equally appropriate or more appropriate to the district than the existing nonconforming use. In permitting such change, the Board of Adjustment may require appropriate conditions and safeguards in accordance with the provisions of this chapter;
D. 
Any structure, or structure and land in combination, in or on which a nonconforming use is superseded by a permitted use shall thereafter conform to the regulations for the district, and the nonconforming use may not thereafter be resumed;
E. 
When a nonconforming use of a structure, or a structure and premises in combination, is discontinued or abandoned for one year and a day (except when government action impedes access to the premises), the structure or premises in combination shall not thereafter be used except in conformity with the regulations of the district in which it is located; and
F. 
Where nonconforming use status applies to a structure and premises in combination, removal or destruction of the structure shall eliminate the nonconforming status of the land. "Destruction" for the purpose of this subsection is defined as damage to an extent of more than 50% of the replacement cost at time of destruction.
A. 
On any nonconforming structure or portion of a structure containing a nonconforming use, work may be done in any period of 12 consecutive months on ordinary repairs, or on repair or replacement of nonbearing walls, fixtures, wiring, or plumbing, to an extent not exceeding 10% of the current replacement cost of the nonconforming structure or nonconforming portion of the structure as the case may be, provided that the cubic content existing when it became nonconforming shall not be increased.
B. 
If a nonconforming structure or portion of a structure containing a nonconforming use becomes physically unsafe or unlawful due to lack of repairs and maintenance, and is declared by any duly authorized official to be unsafe or unlawful by reason of physical condition, it shall not thereafter be restored, repaired or rebuilt except in conformity with the regulations of the district in which it is located.
C. 
No structural alterations may be made other than those ordered by the Code Enforcement Officer to assure the safety of nonconforming building or structure.
D. 
Nothing in this chapter shall be deemed to prevent the strengthening or restoring to a safe condition of any building or part thereof declared to be unsafe by any official charged with protecting the public safety, upon order of such official.
Any use which is permitted as a special exception in a district under the terms of this chapter (other than a change through Board of Adjustment action from a nonconforming use to another use not generally permitted in the district) shall not be deemed a nonconforming use in such district, but shall without further action be considered a conforming use.
