1. 
Group Home Regulations — Findings And Intent.
a. 
Findings. The Board of Aldermen finds and determines that the policy of the City is to:
(1) 
Provide handicapped persons who are protected under Federal and State fair housing legislation equal opportunities to live within all residential zone districts within the City;
(2) 
Disperse the location of group homes throughout the City through reasonable separation requirements;
(3) 
Comply with the principles, policies and regulations of Federal and State fair housing legislation; and
(4) 
Support and enhance the viability and quality of neighborhoods and residential communities for the benefit of all City residents.
b. 
Intent. The intent of these regulations is to enable Type A group homes to locate in residential communities and to increase opportunities for integration of these homes in residential neighborhoods. For classes or groups of individuals not protected under Federal and State fair housing legislation or for Type A group homes exceeding the occupant limit specified in Section 405.080, these regulations are intended to provide a review process whereby the intended use of a group home is evaluated to determine its compatibility with the surrounding land uses and its conformance with applicable criteria of approval as more fully set forth herein.
2. 
General Provisions. Unless otherwise expressly stated, a Type A or Type B group home must meet the following minimum requirements:
a. 
Licensing. The applicant is or will be licensed by the State of Missouri to operate the facility or is not required to be licensed.
b. 
Separation. No group home may be located within a one (1) mile radius of any other group home, as measured by a straight line from the closest point of property line to property line.
c. 
Density. Each group home shall maintain a minimum living area equal to one hundred sixty (160) square feet per occupant exclusive of kitchen areas, dining areas and a common living area. Additionally, each such group home shall a minimum of one (1) full bathroom per three (3) residents.
d. 
Parking. The group home must have adequate off-street parking.
e. 
Building, Fire And Safety Codes. The proposed occupancy of the group home complies with or will comply with the requirements of the currently adopted building, fire and safety codes of the City as well as all applicable requirements of the zone district or planned unit development.
f. 
Threats To Public Safety. As authorized by 42 U.S.C. § 3604(f)(9), no group home shall provide housing to any individual whose tenancy would constitute a direct threat to the health or safety of other individuals or whose tenancy would result in substantial physical danger to the property of others.
g. 
The group home has no officer or staff member in its operating agency that has ever been convicted of a felony or misdemeanor involving moral turpitude.
h. 
The person granted a license under this Subsection has not had a license revoked under this Subsection in the last five (5) years.
i. 
The person granted a license under this Subsection has not been denied a license during the preceding three (3) years.
j.

3. 
Specific Provisions.
a. 
Special Use Permit. Any Type A or Type B group home as defined in this Code shall file an application and obtain a special use permit from the Board of Aldermen prior to occupancy. The policies and procedures for obtaining the necessary special use permit are detailed in Section 405.080(F)(3)(d) herein.
b. 
Reasonable Accommodations.
(1) 
The Federal Fair Housing Act, 42 U.S.C. § 3601 et seq., as amended, requires that local governments be prepared to make "reasonable accommodations" in order to permit housing for certain protected individuals to occur in residential areas. In response to a written application identifying the type of housing being provided and the portions of the Fair Housing Act that require reasonable accommodations be made for such housing, the City Building Inspector, or his or her designee, in consultation with the Board of Aldermen, is authorized to approve minor modifications of building setbacks, height, lot coverage or occupancy limits in order to provide reasonable accommodations without the need for an additional approval process.
(2) 
The Building Inspector, or his or her designee, may approve a type of reasonable accommodation different from that requested by the applicant if the Building Inspector concludes that a different form of accommodation would satisfy the requirements of the Federal Fair Housing Act with fewer impacts on adjacent neighborhoods. The decision of the Building Inspector shall be accompanied by written findings of fact as to the applicability of the Fair Housing Act, the need for reasonable accommodations and the authority for any reasonable accommodations approved.
c. 
Occupancy Limits. If an applicant for a Type A group home seeks to house more than eight (8) individuals (excluding support personnel) or is denied a reasonable accommodation to increase the number of occupants within the group home, it may seek approval for a Type B group home permit in conformance with Subsection (F)(3)(d) herein.
d. 
Special Use Permit — Type A And Type B Group Homes.
(1) 
General. In addition to the general requirements for all group homes specified in Section 405.080(F)(2) above, all Type A or Type B group home shall not locate or operate within the City unless it has received approval by the City in the form of a written special use permit in conformance with this Section.
(2) 
Purpose. The Type B group home review and approval procedure provides a discretionary approval process for group homes with potentially widely varying operating characteristics. The procedure encourages public review, agency referral and evaluation of a Type B group home's operating characteristics and site development features and is intended to ensure that a proposed group home will not have a significant adverse impact on surrounding uses and neighborhoods within the City.
(3) 
Pre-Application Conference. An applicant of a Type A or Type B group home shall schedule and attend a pre-application conference with appropriate City staff before filing a group home permit application. The purpose of the pre-application conference is to inform the applicant of applicable procedures, submittal requirements and other pertinent matters to assist the applicant in completing an application.

Any application that is not accompanied by the required fees shall be deemed incomplete.
(6) 
Notice. If the City determines that the application is incomplete, the appropriate City staff shall notify the applicant of that fact and specify the specific ways in which the application is deficient. No further processing of the incomplete application shall occur until the deficiencies are corrected.
(7) 
Planning And Zoning Review. Upon acceptance of a complete application and satisfaction of the referral process, the application shall be forwarded to the Planning and Zoning Commission. The Planning and Zoning Commission shall hold a public hearing on the application, and within sixty (60) days from the date of receipt of a complete application make a recommendation to the Board of Aldermen based on the approval criteria.

(12) 
Prohibition Of Permit Transfer. A group home special use permit is issued to a specific operator or organization and shall not be transferable to another individual or party for the same location during the term of the permit.

(13)

If any provision of this Section should be found by a court of competent jurisdiction to be invalid, such invalidity shall not affect the remaining portions or applications of this Section that can be given effect without the invalid portion, provided that such remaining portions or applications of this Section are not determined by the court to be inoperable.
