A. Residential Exterior Building Design and Materials: In order to protect the historic integrity established by the existing buildings in the R-9 zone, the building design and exterior finishes of all new dwellings, including multiple-family dwellings, garages, or accessory structures, and new additions or exterior remodeling of existing buildings or accessory structures after July 31, 2010, shall comply with the following design requirements and materials. Covering of existing exterior brick with any other type of material or paint is prohibited. Properties which are on the local historic register are subject to the requirements of the local landmarks commission and are exempt from these standards if a certificate of historic appropriateness grants approval contrary to these standards.
1. Exterior Solid Wall Surface Materials:
a. Face brick (maximum brick size 2-5/8 inches by 9-5/8 inches). Synthetic brick is not permitted.
b. Wood lap or tongue and groove wood siding that creates horizontal lines, except that this material is not allowed as the main material for a multiple-family dwelling.
c. Hardiplank or similar nonvinyl or nonmetal siding material that creates a horizontal wood lap appearance, except that this material is not allowed as the main exterior material for multiple-family dwellings over two stories in height.
d. Stucco or stucco appearing material so long as there are breaks in the wall plane with brick or stone relief areas, except that this material is not allowed as the main material for a multiple-family dwelling.
e. A combination of brick as the base level material around all four sides of a single-family or two-family dwelling and stucco appearing material, wood or hardiplank type materials above the brick; provided that on single-story buildings the brick extends at a minimum to the bottom of the windowsills and for two-story structures the brick extends at a minimum to the beginning of the second story, and the transition between the two types of exterior materials is defined by a projection of the upper floor beyond the main wall or a break in the wall surface due to a porch roofline.
2. Exterior Solid Wall Accent Surface Materials: There are portions of a wall surface that can be designed as either areas of decoration to a building or provide a continuity of design depending on the design concept of the building. Materials used on gable ends of a building, dormers, bay projections, chimneys, quoins, pillars and other ornamental features have a wider variety of design patterns and materials and are not limited to materials with horizontal lines. Materials that are allowable for these features are:
a. the same brick, wood, stucco, or hardiplank or similar nonvinyl or nonmetal siding material that creates a horizontal wood lap appearance used on the main walls of the building.
b. stucco, wood, or synthetic materials that have a wood or stucco appearance and create a variation of patterns that accent the architectural feature.
c. brick, stone or synthetic stone in patterns different from the major wall material.
3. Windows on Wall Surfaces Facing a Public Street: The minimum amount of glass for the ground floor level of a single-family or two-family dwelling facing the street is 15% of the wall surface and, for single-family or two-family dwellings on a corner lot, 10% of the wall surface facing the side street. For two-story single-family or two-family dwellings, the minimum amount of glass for the second story is 10% of the wall surface facing the street and, for the second story of a single-family or two-family dwelling on a corner lot, 7.5% of the second story wall facing the side street. A multiple-family dwelling shall have, at a minimum, the same amount of glass on all levels of the building as the main level.
4. Roof Design and Materials: Only roof designs that either are gabled, gambrel, or hip design are permitted for single-family or two-family dwellings; except that multiple-family dwellings may have a flat roof. The minimum roof slope is three to twelve (3 rise to 12 length) for pitched roofs. The roof exterior surface for pitched roofs is limited to asphalt shingles, wood shake or shingle, tile or tile appearing material or composite materials that have the same visual appearance as the permitted materials.

Gambrel
Hip

b. The main entrance into a new multiple-family dwelling shall have a covered porch that faces the street.
c. The roof covering over the porch shall be an extension of the building design and building materials and shall have a minimum projection over the front door of four feet (4') and a maximum of eight feet (8').
d. Any new porch:
(1) shall be a minimum of five feet wide along the front face of the building and, for single-family dwellings and two-family dwellings, may extend the full length of the front of the dwelling;

7. Garage Requirement, Design, Exterior Material, Locations and Other Parking Regulations:
a. New attached garages shall have the same exterior wall treatment as the dwelling to which the garage is attached.
b. Detached new or remodeled garages located behind the home on an interior lot may have either the same exterior wall treatment as the dwelling or may use one of the solid wall surface materials listed under Subsection A.1.
c. A garage constructed after July 31, 2010, shall have the same roof slope as the dwelling, shall use the same material used in the gable ends of the roof of the dwelling if such roof treatment exists on the dwelling, and the eave line of the garage roof facing the street shall have the same detail/ornamentation that is present on the exterior of the dwelling facing the street. If no ornamentation exists on the dwelling, none is required on the garage. Roofing material for the garage shall be the same roofing material as the home.
d. A new garage constructed on an interior lot may be freestanding and set back behind the back line of the home or attached to the rear of the home with either a side or rear garage door for vehicle entry into the garage.
