The Ideal Preservation Approach
The size, type, and placement of windows are important defining features of historic structures. To preserve the historic appearance and value of a structure, the original windows should be preserved whenever possible. The ideal approach would involve the following:
· Providing adequate protection and regular maintenance to windows to prevent their deterioration
· Repairing rather than replacing damaged windows, using similar materials
· Replacing windows that cannot be repaired with windows of similar type, for example, replacing original wooden sash windows with new wooden sash windows
· Maintaining the original size, shape, and rhythm of window openings on portions of structures visible from the street
The more nearly a project conforms to the ideal, the more likely it will be approved.
Window Projects NOT Requiring a COA
If a property owner proposes any of the following projects, a COA is not required:
· Cords, weights, or sashes are to be repaired
· Broken window panes are to be replaced using similar glass
Window Repair or Replacement as a Minor Alteration Requiring a COA from City Staff
If a property owner proposes any of the following projects, the city Planning and Development Services Manager will evaluate the COA application for consistency with the ideal preservation approach:
· An original window is to be repaired with similar materials and left in its original opening
· An original window is to be replaced with the same type of window
· Unhistorical elements or materials are to be replaced with historical elements or materials
Window Modification or Replacement as a Major Alteration Requiring a COA from the Commission
If a property owner proposes any of the following projects, the Historic Preservation Commission must evaluate the COA application for consistency with the ideal preservation approach:
· Historic window trim is to be altered or removed
· Historic window accent material such as wood, cast iron, or bronze is to be removed
· Replacement windows are to be installed that do not fit historic openings
· The historic appearance of windows it to be modified using designs, materials, and finishes that noticeable change the sash, depth of reveal, muntin configurations, glazing, or frame
· Windows are to be replaced because of broken glass, broken counter-weight ropes, stuck sash, or high air filtration when they could be repaired
· Any project that is referred to the Commission by the Planning and Development Services Manager because of the particular design issues involved
