L. Additions
1. Locate exterior additions at the rear of or on an inconspicuous side of a historic building, limiting the size and scale in relationship to the historic building, and using appropriate proportions.
2. Design new additions so that it is clear what is historic and what is new.
3. Consider the attached exterior addition both in terms of the new use and the appearance of other buildings in the historic district. Additions shall be distinguishable from the historic building, but shall be compatible in terms of mass, materials, size, texture, and scale. Additions shall be designed so they can be removed without destroying the form of the historic building.
4. New additions should not be visible from streets.
6. Do not cause a loss of historic character through a new addition.
M. Auxiliary or Outbuildings
1. The design of outbuildings such as garages shall acknowledge and suggest the function of original outbuildings that would have been located in the neighborhood.
2. The design of features like garage doors that face the street shall mimic carriage house doors from an era consistent with the primary building on the lot.
3. Garages shall be located to the rear of the primary building on the lot.
4. Materials used in constructing outbuildings or accessory buildings may only use materials and design characteristics selected from the following list: wood lap siding with a four inch lap or board and batten; a 12/12 roof pitch; overhanging eaves; exposed rafter tails; wood windows; masonry but not exposed concrete block or split-face block; garage doors appearing to be carriage doors or plank doors with x-bracing or perimeter reinforcing timbers.
Roofs
2. The eaves on additions or new buildings shall have an overhang that mimics existing buildings near the property. A minimum eave overhang of at least eight inches must be retained or used on new buildings or additions to existing buildings.
3. Repair or replace roof details (chimneys, roof cresting, finials, attic vent windows, molding, bargeboards and other unique roof features). Use some of these details in designing new buildings.
4. Materials used in roofing existing buildings or new construction shall duplicate the roofing materials originally found in the neighborhood. Asphalt or fiberglass shingles can be appropriate, as are wood, slate, standing seam metal, or metal shingle or tile roof coverings. The color of roofing materials should be a dark green, charcoal gray, black or dark reddish brown to simulate the original roof colors.
5. Do not place solar collectors or modern skylights on roof areas that are visible from the street, and do not install them where they interfere with decorative roof elements.
B. Windows
1. Original windows shall be reused if possible. It will be much less expensive and much better historically to retain the original windows, and it is inappropriate to replace them with new windows that differ in size, material or pane division.
2. If replacement windows are necessary, they shall be the same overall size as the originals, with the same pane division and the same muntin depth, width and profile. They shall be the same materials as the original windows, which were generally wood.
3. True divided lights shall be used in replacement window sashes with more than one pane.
C. Porches
2. Design elements to be incorporated in any new porch design must include tongue and groove wood floors, beadboard ceilings, wood posts and/or columns and sawn and turned wood trim when appropriate. If balustrades are required, they must be designed with spindles set into the top and bottom rails.
5. Porches and balconies visible from a street may not be enclosed unless the enclosure provides as much transparency as existed prior to the enclosure and is designed to be immediately removable.
D. Entrances
6. Service (rear) entrances may not be altered to make them appear to be formal entrances by adding paneled doors, fanlights, transoms or sidelights.
7. Secondary entrances must be compatible with the original in size, scale and materials, but clearly secondary in importance.
