Group Homes.
(1)
Purpose. The City has determined that it is necessary
and desirable to provide suitable sites for group homes in residential
areas while, in furtherance of the recognized goals of deinstitutionalization
and dispersal, assuring that group homes are not unduly concentrated
in neighborhoods so as to afford mentally or physically disabled persons
every opportunity to be integrated in the community. To that end,
group homes in residential districts shall comply with the following:
(a)
To promote deinstitutionalization and dispersal,
no group home may be located within five hundred (500) feet of another
group home, measured by the straight line distance between the nearest
points of the exterior walls (exclusive of overhangs) of the buildings
within which the relevant facilities or uses are located;
(b)
Adjoin any lot upon which another group home already
exists; or
(c)
Be separated from any lot upon which an existing
group home already exists only by a street or roadway.
(2)
The exterior appearance of the home and property,
occupancy limitation, signage and other standards applicable to single-family
dwellings shall apply equally to group homes.
b.
Foster Homes.
2.
Churches, synagogues and other houses of worship.
3.
Municipally owned or operated parks or playgrounds.

that no such building shall be located within a required yard or within
twenty-five (25) feet of any lot line and no trees shall be removed
for the placement of such temporary building. The temporary building
shall be removed upon the earlier occurring of one (1) year from initial
placement of the temporary building or upon the completion or abandonment
of the work, unless express written permission to continue the location
of such temporary building is granted by the Board of Aldermen upon
good cause shown.

premises or visit the premises with a frequency of more than one (1)
visit per day; and
(4)
No steady or concentrated visitation of clients
to the premises which would disrupt the residential character of the
surrounding neighborhood results from the conduct of the customary
home occupation and, in the case of customary home occupations involving
teaching or other types of instruction, visitation shall be limited
to one (1) pupil at a time except for occasional seminar groups.
b.
Persons wishing to maintain a home occupation in accordance
with this Section shall submit to the Code Enforcement Official a

the application. Upon receipt of a complete application, the Code
Enforcement Official shall verify whether the proposed home occupation
complies with the foregoing requirements and, accordingly, shall issue
or deny the application for the home occupation. Following approval
of an application in accordance with this Subsection, any change in
the amount of floor area occupied by the home occupation as certified
in the original application or any change in the type of home occupation
shall require a new application, together with the payment of the
application fee and review and approval in accordance with this Section.
