Sec. 27.04. - Frontage types.

A.   Urban general.

   1.   Intent. The intent of the Urban General frontage type is to create a pedestrian-friendly, compact, mixed-use district. This frontage type is intended for the most density in Dearborn, in the East and West Downtowns and along primary corridors.

   B.   Storefront.

      1.   Intent. This additional designation in Urban General District requires ground floor storefront uses and architectural requirements in order to preserve the walkable, active downtown interface with the public realm. Storefront buildings shall also meet the design specifications for the Urban General Frontage, except as provided herein:

         (a)   Fenestration.

            i.   Ground floor fenestration shall comprise between 70% and 90% of the ground story façade.

            ii.   Ground floor windows may not be made opaque by window treatments (except operable sunscreen devices). A minimum of 80% of the window surface shall allow a view into the building interior for a depth of at least 12 feet.

            iii.   The bottom of the window must be no more than 3 feet above the adjacent exterior grade.

         (b)   Horizontal articulation.

            i.    Horizontal articulation is the arrangement and proportion of façade materials and elements (windows, doors, columns, pilasters, and bays) into discreet bays.

            ii.    For each block frontage, facades shall be divided into discreet horizontally articulated bays at no greater than 60 feet each.

            iii.    Adjacent façades shall contain different wall materials and rhythm of bays to distinguish each storefront in the horizontal plane.

            iv.    There shall be a minimum of one functional entrance every full 25 feet of frontage.

         (c)    Ground floor articulation.

            i.    Storefront buildings shall be designed to create a distinct and separated ground floor area through the use of a horizontal expression line, such as a string course, change in material or textures, awnings or canopies, or sign band between the first and second stories.

   C.   Urban mixed-use.

      1.     Intent. The intent of the Urban Mixed-Use frontage type is to accommodate a flexible variety of uses and scales; preserve historic detached houses; integrate context-sensitive mixed-uses; and serve as a transition from the denser Urban General frontage types to surrounding residential neighborhoods.

D.   Mixed Residential.

   1.    Intent. The Mixed residential frontage type is intended to accom modate a mixture of housing types. Historically, these areas were single-family neighborhoods that have transitioned over time to include a mixture of housing types. Historic single-family houses should be retained where possible for their character and infill housing should respect the established scale and massing.

Illustrative example of the intent of this district.

 

Detached Single Family Homes	Must comply with the regulations for RA- One Family Residential District as outlined in Sections 29.02 and 2.05. All standards related to single-family homes, including those found in Article 2, Article 4, and Article 5, must also be met.
	Homes determined to be new construction per Article 3.00 must also comply with the parking setback in Section 27.04 D.
