A nonconforming lot shall be developed in conformity with all applicable Township regulations except as provided below. However, if it is a lawful preexisting nonconforming lot of record, it may still be developed even if the lot's area and/or width do not meet the Township's requirements. Improvement of a lawful preexisting nonconforming lot cannot otherwise violate other dimensional requirements or increase the existing nonconformity, except pursuant to an approved zoning variance.
A. Residential use of a nonconforming lot. A single, permitted by right principal residential use and its customary accessory uses may be constructed, reconstructed or expanded on a lawful preexisting nonconforming lot, provided all of the following additional requirements are met:
(1) The lot must be a lawful preexisting nonconforming lot of record. All federal, state and local wetland regulations shall be met.
(2) Sewer or septic system and applicable well requirements shall be met.
(3) If the subject lot is in a recorded subdivision having yard setback requirements set forth on the recorded subdivision plan or in the recorded deed, those delineated yard setbacks shall be applied in place of the zoning yard requirements.
(4) If no yard setback requirements are set forth on the recorded plan or in the recorded deed, the following shall be applied for a single-family dwelling unit:
(a) Lots having a width of 100' or greater but less than 150' shall have a minimum side yard setback of 20'.
(b) Lots having a width of 79' or greater but less than 100' shall have a minimum side yard setback of 15'.
(c) Lots having a width of 49' or greater but less than 79' shall have a minimum side yard setback of 12'.
(d) Lots having a depth less than 100' shall have a minimum front yard setback of 30'.
(e) Lots having a depth less than 100' shall have a minimum rear yard setback of 20'.
(f) Triangular lots shall have a minimum front yard setback of 25'.
(g) Triangular lots shall have a minimum rear yard of 15'.
B. Non-residential use of a preexisting nonconforming lot. If a lawful preexisting nonconforming lot is proposed for or occupied by a principal non-residential use, then a building may be constructed on it for any use permitted by right in that district in which the lot is located provided that all requirements are met except for the existing lawful nonconformity, including the off-street parking and loading requirements and yard requirements for the applicable district.
