The provisions of this chapter shall apply to every use and zoning lot in every zoning district.

If before the effective date of this ordinance, or amendment thereof, a building permit was lawfully issued for a structure not in conformity to this ordinance, or such amendment, the construction authorized by such permit may not be started after such date.

In any district in which garage apartments are permitted, a garage apartment which contains not more than one dwelling unit may be established in addition to a principal dwelling structure provided, however, that such garage apartment will be the only additional dwelling unit on the lot. The first floor area of any garage apartment must not exceed 1,250 square feet.

Home occupations are permitted in the RC, AG, AR, and OCM Districts and will conform to the following conditions:

1. All home occupations, collectively, will not occupy more than one-third of the gross floor area of such dwelling unit.
2. There will be no exterior evidence of any home occupation.
3. No article, product, or service sold in connection with such activity will be other than those produced on the premises.
4. No mechanical equipment will be used in connection with such activity other than such equipment as is customary for domestic or household purposes.
5. No full-time employees will be engaged in such home occupation.
6. In addition to other uses deemed unacceptable, the following uses will not be considered home occupations:
   1. Animal hospitals, kennels or stables
   2. Dancing schools
   3. Funeral homes
   4. Medical or dental offices or clinics or hospitals
   5. Employee dispatch centers
   6. Restaurants
   7. Tourist homes
7. Zoning permits will be required for all home occupations.

All commercial and industrial uses established following the effective date of this ordinance will be required to provide screening between the commercial or industrial use (including parking for such use) and adjacent residential uses.

Screening will consist of a twenty foot (20') width of opaque vegetation, to include trees and shrubs in the following combination per one hundred feet (100'):

• 22-26 large shrubs
• 3 understory trees
• 3 canopy trees

Existing vegetation may be used to meet screening requirements. If existing vegetation is of sufficient density, as determined by the Zoning Administrator, the buffer width may be reduced to fifteen feet (15').
