[Ord. 984, 12/14/2015]
This Part shall apply to all nonconforming uses, structures and lots, as defined by this chapter. Nothing contained herein shall require any change in the overall layout, plans, construction, size or designated use of any development, building, structure or part thereof for which official approval and required permits have been granted prior to the effective date of this chapter or any amendment thereto.
[Ord. 984, 12/14/2015]
These regulations shall apply to any use of a structure or lot in any zoning district that is a nonconforming use as defined by this chapter. Whenever the boundaries of a zoning district are changed so as to transfer an area from one zoning district to another zoning district of a different classification, these regulations shall apply to any uses that thereby become nonconforming.
1301.1. 
Continuation and Sale. Where, at the effective date of adoption or amendment of this chapter, a lawful use of a lot or structure exists that is made no longer permissible under the terms of this chapter as enacted or amended, such use may be sold or otherwise transferred to other owners and may be continued as long as it remains otherwise lawful in accordance with the provisions of this Part.
1301.2. 
Enlargement or Expansion. No nonconforming use shall be enlarged or extended onto property which was not owned at the time the use became nonconforming. A nonconforming use shall not be enlarged or expanded unless the Zoning Hearing Board shall interpret that the enlargement or expansion is necessitated by the natural expansion and growth of trade of the nonconforming use. Any such enlargement or expansion shall conform to the area, height and yard requirements of the Zoning District in which it is located, unless the Zoning Hearing Board grants a variance.
1301.3. 
Change of Use.
A. 
A nonconforming use shall not be changed to any use other than a conforming use, except as permitted as a use by special exception by the Zoning Hearing Board in accordance with the following standards:
(1) 
The new nonconforming use will more closely correspond to the uses authorized in the district as permitted uses, conditional uses or uses by special exception.
(2) 
The new nonconforming use will be in keeping with the character of the neighborhood in which it is located and will have an equal or lesser impact on the neighborhood than the existing nonconforming use.
(3) 
Any change from one nonconforming use to another shall comply with the parking requirements of Part 11 for the new use and shall be subject to the area, bulk and buffer area regulations for such use in the zoning district where such use is authorized as a permitted use, conditional use or use by special exception.
B. 
When a nonconforming use is changed to a conforming use, the use thereafter shall not be changed to a nonconforming use.
C. 
In the R-1 and R-2 Districts, where a nonconforming use exists on a lot, a conforming use shall not be established on the same lot unless the nonconforming use is discontinued.
1301.4. 
Abandonment. When a nonconforming use of a structure and/or lot is discontinued or abandoned for 12 consecutive months, the structure and/or lot shall not thereafter be used, except in conformance with the regulations of the zoning district in which it is located.
1301.5. 
Damage or Destruction. Any nonconforming structure damaged by fire, flood, explosion or other casualty may be reconstructed and used as before if such reconstruction is undertaken within 12 months of such casualty and if the restored structure has no greater coverage and contains a cubic content no greater than before such casualty.
[Ord. 984, 12/14/2015]
These regulations shall apply to all nonconforming structures, as defined by this chapter, in all zoning districts.
1302.1. 
Structural Alteration or Enlargement. A nonconforming structure may be enlarged or structurally altered, provided that the enlargement or alteration does not encroach any further into a required yard setback than the existing nonconforming structure does, and further provided that no new nonconformities are created. All other alterations or enlargements shall require review by the Zoning Hearing Board, and after public hearing, the Zoning Hearing Board may determine undue hardship and may authorize a variance for the reasonable alteration or enlargement of such structure.
1302.2. 
Damage or Destruction. Should any such structure, other than a sign, be destroyed by any means to an extent of more than 75% of its replacement cost at the time of destruction, it shall not be reconstructed except in conformity with the provisions of this chapter. In the event that such damage or destruction is 75% or less than the replacement cost of the structure, repairs or reconstruction may be undertaken, provided that such restoration is started within 12 months of the date of destruction and the reconstruction does not increase the nonconformity of the structure.
1302.3. 
Moving. Should a nonconforming structure be moved for any reason for any distance whatever, it shall thereafter conform to the requirements of the Zoning District in which it is located.
1302.4. 
Signs.
A. 
Nonconforming signs may be repaired or reconstructed, provided that no structural alterations are made that increase the gross surface area of the sign; however, nonconforming signs that are damaged or destroyed to an extent of more than 51% of their replacement cost at the time of destruction shall not be reconstructed except in conformity with the provisions of this chapter. Replacement cost shall be determined by the Borough Engineer upon request by the Borough. The Borough Engineer shall inspect the sign and submit a report to the Zoning Officer within 10 working days of the Borough's request. The cost of the services of the Borough Engineer shall be borne by the applicant. Said cost shall not exceed the amount established from time to time by resolution of Borough Council.
B. 
Nonconforming signs shall not be enlarged, added to or replaced by another nonconforming sign, use or structure, except that the interchange of advertising panels shall be permitted, subject to obtaining the sign permit required by § 1202.12.
1302.5. 
Repair or Maintenance. Nothing in this chapter shall be deemed to prevent the strengthening or restoring to a safe condition of any structure or part thereof declared to be unsafe by any official charged with protecting the safety of the public, provided that all other requirements of this section are met.
[Ord. 984, 12/14/2015]
The following regulations shall apply to nonconforming lots, as defined by this chapter:
1303.1. 
Lot Area or Lot Width.
A. 
Where two or more adjacent lots of record with continuous frontage have less than the required area and width and are held by one owner, the lots shall be considered to be an undivided lot for the purpose of complying with this chapter. No division of any lot shall be made which does not comply with the requirements of this chapter. Any change in lot lines necessary to meet the minimum requirements of this chapter shall constitute a revision to the recorded plan and shall meet all applicable requirements of the Borough subdivision regulations.[1]
[1]
Editor's Note: See Ch. 22, Subdivision and Land Development.
B. 
Any lot of record existing at the effective date of this chapter and held in separate ownership different from the ownership of adjoining lots may be used for the erection of a structure conforming to the use regulations of the zoning district in which it is located, without a lot area or lot width variance, even though its lot area and width are less than the minimum required by this chapter; however, such lot shall comply with the front, rear and side yard, height and lot coverage standards of the zoning district wherein it is located.
1303.2. 
Front Yard Setback.
A. 
Where structures exist on adjacent nonconforming lots of record that have front yards that are less than the minimum depth required, the minimum front yard for an adjacent vacant nonconforming lot of record proposed to be built upon shall be the average depth of the nonconforming front yards for the existing structures on the adjacent nonconforming lots in the same block on the same side of the street.
B. 
On lots of record which have recorded building lines which exceed the minimum depth required by this chapter for the front yard, the recorded building line shall take precedence over the front yard required by this chapter in the zoning district in which it is located.
[Ord. 984, 12/14/2015]
1304.1. 
The owner of a nonconforming use shall make an application for registration of the nonconforming use, and upon presentation of documentation acceptable to the Zoning Officer that the use was lawfully in existence prior to the effective date of this chapter or any amendment that created the nonconformity, the Zoning Officer shall register the same on a map and by the Allegheny County Assessor's tax parcel number as a legal nonconforming use.
1304.2. 
In the course of administering this chapter and reviewing applications for zoning certificates, certificates of occupancy or variances, the Zoning Officer shall register all nonconforming structures and nonconforming lots as they become known through the application process.
