The R-4 One-Family Residential District is designed to permit and encourage the erection of specialized single-family dwelling types in areas of the city where this type of housing is proposed on the city's adopted master plan for future land use map. The areas depicted on the master plan map for such development contain residential dwellings. Therefore, the intent of the R-4 One-Family Residential District is to encourage the ultimate redevelopment of these neighborhoods or portions of them, with specialized housing configurations designed to provide an alternative type of quality housing environment.

(Ord. No. 802, § 1, 12-14-2020)

In the R-4 One-family Residential District no building or land shall be used and no building shall be erected except for one or more of the following specified uses, unless otherwise provided in this chapter:

(1)

One-family residential dwellings as regulated in this article.

(2)

Family day care home and group day care home, as defined in this chapter and regulated by state statute.

(3)

Foster family home and foster family group home, as defined in this chapter and regulated by state statute.

(4)

Publicly owned and operated libraries, parks, parkways, and recreational facilities.

(5)

Public, parochial, and other private elementary schools offering courses in general education, but not operated for profit.

(6)

Accessory buildings and structures customarily incident to any of the above permitted uses.

(Ord. No. 802, § 1, 12-14-2020)

The following uses shall be permitted subject to the conditions hereinafter imposed for each use and subject further to review by the planning commission at a duly advertised public hearing:

(1)

All uses permitted and as regulated in Article IV of this chapter.

(2)

One-family attached or detached dwellings in clusters, subject to the requirements of Article XXIV, Schedule of Area Regulations, in this chapter. All such development shall commence at block ends unless an entire block frontage has been approved for cluster housing. When the construction of attached dwellings is approved for an entire block frontage, construction may commence anywhere along the block frontage.

(3)

Single-family detached or attached dwellings permitted under the standards of this district may be developed as single-family site condominiums in accordance with the applicable standards of this chapter and the State Condominium Act 59 of 1978, as amended, or platted in accordance with the Trenton Subdivision Control Ordinance, and the State Land Division Act 591 of 1996, as amended, and Act 525 of 2005.

Since it is the intent of the R-4 district to permit the redevelopment of previously platted land, the replatting of property may become necessary. In that case, care will need to be taken by the developer and the city to make certain that the applicable standards of the Michigan Public Acts 591 and 525 is complied with regarding the replatting of previously subdivided land.

(4)

All single-family dwelling units, attached or detached, shall be provided with a fully enclosed garage. The garage may be an integral part of the main dwelling building, or it may be attached to the dwelling or detached from the dwelling, but in all cases access to the garage shall be from the rear of the building via an improved public alley located at the rear of the property.

(5)

A detached garage shall be located no closer to a public alley right-of-way than three feet and shall observe all building height restrictions of the zoning code pertaining to detached accessory buildings in residential districts.

(6)

Except as permitted in this section, a detached accessory garage shall observe the minimum side yard setback requirements of the zoning code applicable to detached accessory buildings in residential districts.

(7)

For detached dwelling units, one side wall of a detached garage may be located directly along a side yard line of the dwelling it is intended to serve, provided that a five-foot-wide accessible maintenance easement is placed on the abutting property adjacent to the full length of the garage wall. The wall may have windows but no doors. All stormwater run-off from that part of the garage roof along the side yard line shall be channeled to a public drain via the maintenance agreement, except a garage wall of a detached dwelling located on a side yard line may be partly or fully in common with the garage wall of a detached garage on the abutting property. Each garage that is attached to another garage shall be fully enclosed by four walls including the door wall, except a single wall may serve as the common wall between two attached garages. Not more than two detached garages serving two detached dwellings shall be attached one to another.

(8)

When a rear yard is enclosed by a privacy fence or hedge, the restricted clear corner vision requirements of the city's fence control standards shall apply.

(9)

The minimum off-street parking requirements of the zoning code for single-family dwellings may be satisfied by erection of a two-car garage. If a one-car attached garage is erected, the driveway to the garage may serve as a usable parking space, provided the driveway shall be at least 23 feet by nine feet. If a one-car detached garage is erected at the rear of the property, a hard-surfaced parking space equal to 23 feet by nine feet shall be placed on the property next to the garage.

(Ord. No. 802, § 1, 12-14-2020)

The following conditions where applicable shall apply to development in the R-4 districts:

(1)

All public overhead electrical and other communication lines extending from existing utility systems in the block, to a new dwelling unit in the district shall be placed underground.

(2)

When an entire block is to be developed or redeveloped under the guidelines of this district, all public overhead electrical and communication lines existing above ground at the time of construction shall be placed underground within the development or redevelopment area, at the time of construction.

(3)

In those instances where it can be shown that high current in certain electrical lines precludes placing them below ground within a development area, the zoning board of appeals may permit those particular lines to remain above ground provided:

a.

The lines cannot be relocated out of the development area.

b.

The lines are placed within the alley rights-of-way.

c.

The lines are placed on poles of uniform height, diameter, and color.

(4)

In the R-4 district, application of the following detached dwelling unit design guidelines shall apply:

a.

Not more than two walls of any detached garage shall be in common with the wall of another garage serving the same group of attached dwelling units. Walls of detached garages shall not be in common with a wall of any garage serving any other dwelling cluster.

b.

(10)

No accessory building or structure shall be permitted except in conjunction with a principal permitted use. This may include a private marina as defined in this chapter, provided the requirements of Article IV, in this chapter are met.
