It is the intent of this section to allow a variety of major home occupation pursuits as specially permitted uses in residential districts while recognizing the substantial governmental goal of preserving and maintaining the residential atmosphere, appearance and character of residential districts. A major home occupation may be allowed as a special permitted use in the A-80, RR-80, RS-25, R-7.2, R-1-15, R-1-10, R-2, RMF and PD Districts. It is recognized that while major home occupation pursuits are specially permitted under the conditions provided for in this section, it is the primary purpose of this section to preserve and maintain the residential atmosphere, appearance and character of residential districts. It is the stated intent that the special permitted major home occupation use will always be second and subordinate to the principal residential use of the premises and that the major home occupation will not harm other residential uses of the property or adversely affect neighboring premises. Under no circumstance shall a special permitted major home occupation become so extensive that it predominates the principal permitted residential use of the premises. It is further the intent of this section to establish specific performance standards and controls to limit major home occupations so as to minimize the adverse impacts a home occupation could have on a neighborhood or district and to assure that it does not become the predominant use of the property. Finally, it is the intent of this section to exclude family or group family day care as first defined in New York State Social Services Law, § 390, Subdivision 1, Paragraph (d) and (e), which are exempt from the provisions of this chapter, from having to comply with these regulations.
