is of official record by deed or a subdivision duly recorded in the
plat records of Carroll County as of the effective date of this chapter,
provided:
C.
In any district except the C Conservation District,
where dwellings are permitted, if neither a public water supply or
sewerage system is accessible or if an acceptable community water

subject, however, to the requirements of the Maryland State Department
of Health.
Where the average setback line of at least two
existing buildings on lots which are on the same side of the street
or road and within 200 feet of the lot in question is less than the
minimum setback prescribed by this chapter, the minimum setback line
shall be the average setback line of all buildings within 200 feet

nor shall such structure be used for any purpose than a use incidental
to the main use of the building.
B.
In any R or B District, the height of a building may
be extended to three stories, but not over 40 feet, if each side yard
is increased in width 1/2 foot for each additional one foot of height
above the normal maximum limit.
C.
On any lot where the average finished slope adjoining
the building exceeds 7% grade, one story in addition to the number

The Board may authorize, upon appeal, in accordance with § 180-105 variances from height, lot area, lot width, yard regulations, parking space requirements, sign regulations, and distance requirements specified in § 180-16. The Board may grant such variance only in cases where the strict compliance with the terms of this chapter would result in practical difficulty and unreasonable hardship, and only if in strict harmony with the spirit and intent of such regulations and only in a manner so as to grant relief without substantial injury to public health, safety, and general welfare.
