(b1) Restoration (ENCOURAGED) Maintaining the original or unimpaired character of the district as it was at the time of construction. Any restoration done must return the structure to its original state. Authenticity of a restoration would require the removal of incompatible exterior elements and the replacement of all damaged or deteriorated elements with replicas of the same design and materials. New construction shall conform to the guidelines for defined elements of preservation regarding height, proportion, and building materials. A Certificate of Appropriateness (CoA) applicant shall be responsible for documenting the authenticity of the proposed work to the satisfaction of the commission. (b2) Rehabilitation (ADOPTED) Maintaining the existing character of the district, and whenever possible returning it to its original condition. Any rehabilitation would not require the removal of all non-original materials but would encourage the removal of all such materials which are incompatible with the defined elements of preservation for the district. The design of new construction or alteration would not require the duplication of the original design and construction, but should be compatible with existing structures and the district’s defined elements of preservation. The use of original materials or construction techniques would be encouraged, but contemporary methods and materials would be acceptable when compatible. [..] II. EXISTING STRUCTURES A. BUILDING MATERIALS Original exterior building materials in the district include brick, stucco, clapboard, wood shingles, and brick or stone masonry. In some instances, vinyl, composite and aluminum siding have been applied over the original material. Required Original exterior building materials shall be retained when possible. Deterioration of wood materials shall be prevented through repair, cleaning and painting. The existing architectural detail around windows, porches, doors and eaves shall be retained or replaced by replicas of the same design when deteriorated beyond repair. Masonry, including brick and stucco structures, shall be maintained, and properly cleaned only when necessary to halt deterioration or to remove stains and shall be done in a method acceptable for the preservation of th e surface: i.e. low-pressure water and soft natural bristle brushes. Brick or masonry mortar joints should be repointed only when there is evidence of moisture problems, or when sufficient mortar is missing to allow water to stand in the mortar joint. Existing mortar shall be duplicated in composition, color, texture, joint size, method of application and joint profile. When repairing stucco, stucco mixture shall be used. A professional shall make a study of the old stucco, to determine the exact mixture and underlayment used in the original work. Some repair methods are not compatible with the original techniques and may cause early disintegration of the repair work and the original work. Ample ventilation must be afforded the structure when siding is installed, in order to prevent increased deterioration of the structure from moisture and insects. Recommended Whenever possible, the original building materials should be restored. When maintaining or repairing original siding is not feasible, aluminum, vinyl or composite siding may be used. When used over wood surfaces, this siding should be the same size and style as the original wood. Every effort should be made to retain the original trim around windows, doors, cornices gables, eaves and other architectural features. Property owners should contact the Historic Preservation Commission of South Bend and St. Joseph County prior to initiating any restoration or rehabilitation effort. [ Address and contact information is listed in the front of the Guidebook.] The Commission is an invaluable source of information about all facets of rehabilitation and restoration – materials, methods, contractors and the like. Prohibited Wood siding shall not be resurfaced with new materials that is inappropriate or was unavailable when the building was constructed, such as artificial stone, brick veneer, asbestos or asphalt shingles. Sandblasting or the use of harsh detergents shall not be used on masonry including brick, stucco, limestone, flagstone and sandstone. This method of cleaning erodes the surface material and accelerates deterioration.
