The performance standards contained in Part 2 of this Land Use and Development Code shall be fully observed, and any building renovations shall be consistent with the below Historic Preservation Review Standards as determined by the Planning Staff.
A. 
Every reasonable effort shall be made to provide a compatible use for the property which requires minimal alteration and/or replacement to the character-defining features of the structure, object or site and its environment or to use a property for its originally intended purpose.
B. 
The distinguishing original qualities or character of a structure, object or site and its environment shall not be destroyed. The removal or alteration of any historic material or distinctive architectural features is not allowed unless not removing or altering the historic material or distinctive architectural features makes use of the building or site highly impracticable economically.
C. 
All sites, structures and objects shall be recognized as products of their own time, place and use. Alterations that have no historical basis or create a false sense of historical development, such as adding conjectural features or elements from other properties, are not allowed unless highly impracticable economically.
D. 
Changes which may have taken place in the course of time are evidence of the history and development of a structure, object or site and its environment. Changes that have acquired significance in their own right shall not be destroyed.
E. 
Distinctive features, finishes and construction techniques or examples of skilled craftsmanship which characterize a structure, object or site shall be treated with sensitivity.
F. 
Deteriorated historic features shall be repaired rather than replaced unless economically impracticable. Where the severity of deterioration requires replacement of a distinctive feature, the new feature should match the feature being replaced in composition, design, texture and other visual qualities and, where possible, materials. Repair or replacement of missing historic features should be based on accurate duplications of features, substantiated by documentary, physical or pictorial evidence rather than on conjectural designs or the availability of different architectural elements from other structures or objects.
G. 
The surface cleaning of structures and objects, if appropriate, shall be undertaken with the gentlest means possible. Chemical or physical treatments, such as sandblasting, that cause damage to historic materials shall not be undertaken.
H. 
Every reasonable effort shall be made to protect and preserve the house's architectural significance.
I. 
Contemporary design for alterations and additions to the existing house shall not be discouraged when such alterations and additions do not destroy significant cultural, historical or architectural materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the size, scale, color, material and character of the property, neighborhood and environment.
J. 
Wherever possible, new additions or alterations to the house shall be undertaken in such a manner that, if such additions or alterations were to be removed in the future, the essential form and integrity of the property would be unimpaired.
