A. 
Context of character. Residential structures located within commercial districts are at risk of losing their traditional neighborhood character over time as investment continues and changes in use occur. Understanding the elements that define neighborhood character is the first step in preserving it and ensuring that new construction harmonizes with the context. The traditional character of neighborhoods is defined by buildings, as well as trees, fences, sidewalks, and landscaping. Mature street trees located between the sidewalk and the curb define the character of most village streets.
B. 
Purpose. The purpose of these design standards is to preserve the integrity of the traditional neighborhood character of residential structures located within commercial districts. While some residential structures may have been or will be converted to a nonresidential use, these design standards are intended to ensure that the original design and residential integrity of the structure is maintained over time. It is for this reason that future investment in these structures shall preserve and enhance the overall walkability and historic character of the Village through the observation of the guidelines and standards provided herein.
A. 
Structures under regulation. These design standards shall apply to all structures originally built for residential purposes within the Village's commercial zoning districts. This shall include residential structures still occupied by a residential use, such as single-, two-, or three-family dwellings, and converted residential structures now occupied or proposed to be occupied by a nonresidential use, such as retail or office enterprises.
B. 
Historic structures. For this purpose of this article, the term "historic structure" shall refer to all historic properties, local landmarks, and contributing structures identified in the Village of Hamburg Historic District as listed on the National Register of Historic Places. This shall also include all local landmark properties and properties within historic districts so designated by the Historic Preservation Commission under Chapter 44 of the Village of Hamburg Code.
C. 
Supplemental building design standards. The guidelines and standards provided herein are to be used in conjunction with the Village of Hamburg Building Design Standards, which include illustrative examples of the provisions set forth herein. Where there is a conflict in procedure or regulation of property between this chapter and the Building Design Standards, the requirements of this chapter shall take precedence.
D. 
Property owner guidance. Property owners should refer to the guidelines and standards of this article and the Village of Hamburg Building Design Standards as a source of inspiration, innovation, and distinctive solutions when undertaking changes, modifications, or adaptive reuse of single- and two-family structures and properties.
A. 
Site plan review. All exterior, environmental changes proposed for single-or two-family structures within a commercial district shall require site plan review and approval as provided for by Article 44 of this chapter.
