Southfield City Zoning Code

ARTICLE 8

- MULTIPLE-FAMILY RESIDENTIAL DISTRICTS—MEDIUM RISE RMM AND HIGH RISE RMU

Sec. 5.91.- Intent.

The Multiple-Family Residential Districts (Medium Rise) are designed to provide sites for medium-density multiple-dwelling structures adjacent to secondary and major thoroughfares and freeway service drives. This district is designed to provide a zone of transition between secondary and major thoroughfares and/or more intensive uses of land such as high rise office or high rise multiple-family uses and the less intensive uses of land such as low rise multiple-family uses and/or single-family residential. This district is further designed to provide a zone of medium height limitation which may be more desirable than the RMU (High Rise) District which permits unlimited height and could be detrimental to established areas.

The Multiple-Family Residential Districts (High Rise) are designed to provide sites for high-density multiple-dwelling structures adjacent to high traffic generators commonly found in the proximity of Regional Shopping Centers and areas abutting major thoroughfares and expressways. This district is further provided to serve the residential needs of persons desiring the apartment-type of accommodation with central services as opposed to the residential patterns found in the one (1) family residential and RM, Multiple-Family Residential Districts. This district is further designed so as to provide a zone of transition between these major thoroughfares and high traffic generators and other residential districts through more open space.

Sec. 5.92. - Site plan review.

In an RMM or RMU Multiple Family Residential District, no building, structure or land shall be erected or used in an RMM or RMU Multiple Family Residential District unless the site plan therefor has been approved per the provisions of section 5.22.

(Ord. No. 1793, § 6, 8-19-24)

Sec. 5.93. - Uses permitted.

(1)

(b)

The proposed use must be in accord with the spirit and purpose of this chapter and not be inconsistent with, or contrary to, the objectives sought to be accomplished by this chapter and principles of sound planning.

(c)

The proposed use is of such character that the vehicular traffic generated will not have an adverse effect upon, or be detrimental to, the surrounding land uses or the adjacent thoroughfares.

Failure to begin construction within twelve (12) months of approval of the city council shall make the approval null and void unless an extension is requested, in writing, by the applicant and the request is granted by the city council.

(e)

In approving a special use, the city council may attach reasonable conditions regarding the location, character and other features of the proposed use as they may deem reasonable in the furtherance of the intent of this section.

(2)

Uses.

Sec. 5.96. - Area and bulk regulations.

See article 22, schedule of regulations, which limits the height and bulk of buildings, determines the permitted development area and provides minimum yard setback requirements in the RMM and RMU Districts.

It is the intent of this schedule to incorporate a sliding scale density provision which will prevent high density developments in low profile and low rise buildings which will provide a good living atmosphere and environment by controlling the open space in relationship to the dwelling units.

The distance between buildings on the same lot is regulated by the building distance formula and where, because of the building arrangement, the formula is not applicable, the minimum distance between buildings shall be thirty (30) feet (9.15 meters).

The area and bulk regulations shall be regulated as set forth in the "schedule of regulations" in article 22 except that: carports or garages may be located within fifty (50) feet (15.25 meters) of a side or rear property line where such lot line abuts a multiple-family zoning district or a nonresidential zoning district.

Sec. 5.97. - Building distance formula.

In all Multiple-Residence Districts, the minimum distance between any two (2) buildings shall be regulated according to the length and height of such buildings.

The formula regulating the required minimum distance between two (2) buildings (referred to as building "A" and building "B") is as follows:

S = LA + LB + 2(HA + HB) / 6

WHERE

S = Required minimum horizontal distance between any wall of building A and any wall of building B or the vertical prolongation of either.

LA = Total length of building A

The total length of building A is the length of that portion or portions of a wall or walls of building A from which, when viewed directly from above, lines drawn perpendicular to building A will intersect any wall of building B.

LB = Total length of building B

The total length of building B is the length of that portion or portions of a wall or walls of building B from which, when viewed directly from above, lines drawn perpendicular to building B will intersect any wall of building A.

HA = Height of building A

The height of building A at any given level is the height above natural grade level of any portion of portions of a wall or walls along the length of building A. Natural grade level shall be the mean level of the ground immediately adjoining the portion or portions of the wall or walls along the total length of the building.

HB = Height of building B

The height of building B at any given level is the height above natural grade level of any portion or portions of a wall or walls along the length of building B. Natural grade level shall be the mean level of the ground immediately adjoining the portion or portions of the wall or walls along the total length of the building.

Sec. 5.98. - Landscaping.

Landscape plans and green infrastructure/low impact development methods required per article 4section 5.31(21)(b).
