1. The purpose of the R1 zone is to provide regulated areas for Single-Family Dwelling uses at four different low-to-medium density levels. The R1 zone includes the R1-15, R1-12, R1-10, and R1-5 zones. Any R-1-12 and R-1-10 zones shown on the zoning map or elsewhere in the Land Use Code are references to the R1-12 and R1-10 zones, respectively.
2. The purpose of the R2 Zone classification is to accommodate a need for moderate density residential districts incorporating both Single-Family Dwellings and Two-Family Dwellings. Any R-2 zone shown on the zoning map or elsewhere in the Land Use Code is a reference to the R2 zone.
3. The purpose of the R3 Zone classification is to provide residential areas that will accommodate the development of a wide variety of dwelling types, ranging from Single-Family Dwellings through Multiple-Family Dwellings with their associated necessary public services and activities. The R3 zone includes the R3-A and R3-S zones. The "A" in R3-A stands for attached, and generally allows all types of residential dwellings except stacked residences. The "S" in R3-S stands for stacked, and generally allows all types of residential dwellings, including stacked, but excluding single-family detached. The R3 zone is also to provide an orderly transition from less intensive, lower density uses to more intensive, higher density uses. Any R-3 zone shown on the zoning map or elsewhere in the Land Use Code is a reference to the R3 zone.

(Ord. of 1956, § 10-2; Ord. No. 96-35; Ord. No. 99-25; Ord. No. 2006-24; Ord. No. 2009-14; Ord. No. 2009-15; Ord. No. 2010-20; Ord. No. 2015-7, Exh. A, 5-5-2015)

The uses listed below correspond with certain uses listed in the Land Use Tables in Section 104-12-3. Due to the nature of the use, each shall be further regulated as follows:

1. Dwelling Unit design standards. All Dwellings except for a Single-Family Detached Dwelling, shall be designed in accordance with the following minimum design standards:
   
   1. Rooflines. Rooflines shall be broken every 50 feet, with no less than a 12-inch shift between adjacent rooflines.
      
   2. Building massing. The wall massing of building facades shall be broken at least every 30 feet with no less than a six-inch shift in the plane of adjacent walls.
      
   3. Building material. Each building facade that faces the street shall consist of brick, stone, or wood, or a faux material, such as fiber cement, that is hard for the Land Use Authority to distinguish from real brick, stone, or wood. Metal may be used for accent material covering less than 25 percent of any facade, excluding area for window and door openings. At least one of the building materials used on the building facade shall also be used on all other sides of the building.
      
   4. Colors. At least two muted earth-toned colors generally visible from the site are required.
   5. Repetitious building facades. When multiple Dwelling Units with substantially similar floor plans will be located on the same Street Block whether mirrored or not, no less than seven unique Dwelling Unit facade patterns that use unique architectural design features and materials shall be used and distributed in a manner that avoids the obvious repetition of the same pattern, whether mirrored or not, within visual proximity of another. This provision shall not apply to a stacked Multi-Family Dwelling or to any Dwelling Unit within a building that has one common street-facing front entrance and a street-facing facade that gives the visual appearance of a Single-Family Dwelling.
      
2. Temporary building or use. The building or use shall be removed upon completion or abandonment of the construction work.

 ¹ This minimum lot area notwithstanding, at no time shall any subdivision or other development project have a Dwelling Unit density greater than specified in Section 104-12-5.010. After a subdivision or development project has received final approval under these standards, all excess Dwelling Unit density not included in the approval shall be forfeited unless the density in the entire original project area is reconsidered for compliance with density regulations specified in Section 104-12-5.010 and all owners within the affected area consent to the reconsideration.

 ¹ More than one story is when any part of a second story exists behind the facade wall that faces the Side Yard, excluding area within a basement. For example, if a second story is under a gabled roof, and the gable faces the subject Side Yard, then that side of the building is more than one story; but if the gable faces the Rear Yard or Front Yard, and all of the second story on the facade that faces the subject Side Yard is above the roof's eve, then that side of the building is one story.

² No minimum Side Yard Setback is required for a detached garage that shares a common wall with a similarly proportioned and appearing garage on the adjacent lot, as long as both garages are built at the same time.
