The MH One-Family Manufactured Housing District is intended to provide suitable sites for manufactured single-family detached dwelling buildings in an environment of like dwellings in developments that are characterized by somewhat higher dwelling density levels than are characteristic of the other single-family residential dwelling districts in the city, and by the fact that some manufactured dwelling buildings are permitted by federal and state law to exist in the district without conforming to the local codes and ordinances that are applicable to single-family dwelling buildings in the city's other one-family residential districts.

(Ord. No. 802, § 1, 12-14-2020)

(6)

Should a manufactured housing development permit the keeping and storage of recreational equipment, such as, but not necessarily limited to, boats, including jet skis, snowmobiles and utility trailers, adequate area for the parking and storage of such equipment shall be provided in accordance with the following guidelines:

a.

They shall be restricted to a central or collective parking area.

(7)

All manufactured home pads or supporting piers, as well as all anchoring devices, shall be designed to, and shall comply with, the applicable standards of the Mobile Home Commission Act (MCL 125.2301 et seq.).

(8)

Each manufactured home shall be provided with a skirt, which shall extend downward in a vertical line perpendicular to the bottom of the home, to the manufactured home pad, or to the surface of the ground directly under the outside edge of the home. The skirt shall extend completely around the home structure in a uniformly continuous manner and shall consist of material approved by the state manufactured housing commission. All skirting shall be securely anchored in place in a manner acceptable to the state manufactured housing commission.

(9)

A manufactured housing development shall provide the equivalent of one deciduous tree for every other home site within the development; except an existing tree on a home site may count towards this requirement, provided the tree is in a healthy, growing condition. An existing tree's state of health shall be determined after site construction and final grading of the area around the site has been completed. Deciduous trees planted to fulfill this requirement shall have a caliper (diameter) of not less than two inches at a point ten inches above the ground at the base of the tree, and no such tree shall be less than ten feet in height at the time of planting. A general rule to follow would place such trees no closer than 40 feet on centers.

(10)

General lighting within a manufactured housing development shall follow the guidelines set forth and regulated in Rule 929 of the Michigan Manufactured Housing Code, as amended.

(11)

In addition to the foregoing requirements of this subsection, the following standards shall also apply:

a.

Dwelling density. A manufactured housing development shall contain sites averaging 5,500 square feet per home site; except, when averaging lot area, no home site shall be reduced in size by more than 20 percent, or result in any lot containing less than 4,400 square feet. For each square foot of land area gained through the reduction of lot area below 5,500 square feet, at least an equal amount of land shall be dedicated as open space area within the manufactured housing development. Any open space gained through lot averaging shall be in addition to that required under R125.1946, Rule 946 and R125.1941 and R125.1944, Rules 941 and 944 of the Michigan Administrative Code, as amended.

b.

Dwelling setbacks. Each individual manufactured home shall be placed on a home site of sufficient width and area so that the site will permit the home to comply with the minimum required front, sides and rear yard setback requirements set forth in Rules 941 and 944 of the Michigan Manufactured Housing Code, as amended.

c.

Building height. The maximum height of a building designed to serve as a community center or similar use in a manufactured housing development shall not exceed two stories or 35 feet in height, whichever results in the lesser building height. Storage or service buildings shall not exceed 15 feet in height.

d.

Floor area. In a manufactured housing development, no manufactured home shall contain less than 720 square feet of floor area, measured from the outside walls of the structure.

e.

Parking. Motor vehicle parking spaces within a manufactured housing development shall be provided in accordance with the applicable requirements of Rule 925 and Rule 926 of the Michigan Manufactured Housing Code, as amended.

f.

Site plan review. A site plan shall be submitted to the city for review by the planning commission. The site plan shall be a general plan view drawing containing all applicable information set forth by the city's site plan review procedures. An adequate number of copies of the site plan, along with a copy of the site plan review application form, shall be submitted. When the planning commission finds the site plan to be in order and in compliance with the applicable requirements of this chapter, it shall approve the site plan. Upon granting site plan approval, the city shall forward a copy of the approved site plan and all correspondence pertaining to the site plan to the state manufactured housing commission. During its review of the site plan, should the manufactured housing commission cause significant revisions to be made to the approved site plan, additional copies of the revised site plan shall be forwarded to the Trenton Planning Commission for revised site plan approval. Upon granting revised site plan approval, the city shall forward the approved site plan and all correspondence pertaining to the site plan to the manufactured housing commission. For purposes of this subsection, minor revisions to a site plan approved by the city shall not warrant subsequent review and approval by the city. The manufactured housing commission staff may, at its discretion, determine if the revisions to an approved site plan are significant enough to warrant resubmitting a revised site plan to the city for further review and approval.

g.

Screening. Whenever a manufactured housing development shall provide an area for the storage of recreational equipment, as set forth in this section, or wherever a peripheral property line of a manufactured housing development fronts on a public road right-of-way, the following screening requirements shall apply:

i.

On-site storage areas. When included as part of a manufactured housing development, the storage area shall provide, in addition to the required security fence, landscape screening in the form of planting materials composed of evergreen trees or shrubs, or combinations thereof, which shall not be less than three feet in height at the time of planting and which shall be spaced so as to create a continuous screen at maturity. The screen shall be of a uniform nature and shall be required on all sides of the storage area that abut home sites within the manufactured housing development or abut a single-family residential zoning district along a peripheral property line.

ii.

Abutting public road rights-of-way. A screening buffer shall be provided. The buffer screen shall be placed between the road right-of-way line and the development, and may consist of a landscaped earth berm, or evergreen trees or shrubs, or combinations thereof. When evergreen planting materials are used, they shall follow the spacing and height guidelines set forth in Article XXVII in this chapter.

iii.

Exterior equipment screens. The applicable requirements of Article XXVII in this chapter pertaining to exterior equipment and trash receptacle screening, may apply to all site-built buildings erected in a manufactured housing development.

h.

Loading and unloading. A site-built building erected within a manufactured housing development may be subject to the applicable requirements of Article XXVI in this chapter pertaining to off-street loading and unloading.

i.

Residential entranceways. Any entranceway structure erected in conjunction with a manufactured housing development, including but not limited to, walls, columns and gates, and which is designed and intended to mark an entrance to a manufactured housing development, may be erected in any required yard, provided the restricted clear corner vision requirements of Article XXIX in this chapter.

j.

Clear corner restriction. No fence, wall, shrubbery, sign or decorative entranceway structure, or other obstruction to vision over two feet in height, measured from the established street grade, shall be placed within a triangle formed at the intersection of two public street rights-of-way lines, or within a triangle formed at the intersection of a public street right-of-way line and the nearest edge of an intersecting private drive entrance into a manufactured housing development. The clear vision triangle shall be formed by a straight line drawn between such right-of-way lines, or right-of-way line and driveway edge, from a point 25 feet back from their point of intersection.

k.

Permits. In regard to any manufactured housing unit in the city, the building department shall conduct inspections for a fee, established by ordinance, to determine if a manufactured home in a manufactured housing development has been installed in accordance with the manufacturer's setup instructions or the applicable requirements of the Michigan Manufactured Housing Code, particularly part 6 of the code, and shall conduct inspections when the city has reason to believe that the Manufactured Housing Act or code has been violated, as set forth in Sections 17(2) (MCL 125.2317) and 36 (MCL 125.2336) of the Mobile Home Commission Act. The city shall review and act on plans and inspect and issue building and occupancy permits for any site-built building in a manufactured housing development, and enforce the standards of this article, construction codes and all other ordinances of the city.
