The regulations and standards of this chapter are intended to preserve and protect the single-family residential character and the historic and architectural integrity of the HC Historical Claremont District while allowing for sensitive and compatible alterations, additions, and in-fill development. The character-defining features of the area, including scale, density, setbacks, development patterns, architecture, workmanship, materials, and landscape, must be maintained. Existing architectural elements and materials should be preserved in alterations and repairs. The restoration of deteriorated materials is encouraged. New additions and new development shall be sensitive to existing design patterns and scale. New materials shall be compatible with existing materials.
The HC Historical Claremont District is the oldest residential area in the City. The history of the neighborhood is evident in the large number of historically significant structures still maintained as single-family residences. The homes exhibit a variety of building styles from the turn of the century to the 1940's, and they show a quality of workmanship and character not often found in current times. An interesting and livable pattern of urban design has resulted from the area's earliest stages of development. The homes vary in size, but are usually set back amidst tall trees on streets laid in a grid pattern featuring parkways planted with street trees. One development pattern evident is that large homes are mixed with small homes, and the corner house tends to be larger and more predominant, serving as anchors for the rest of the block. Another pattern is that garages are frequently accessed from or located to the rear of properties, making for an attractive streetscape.
The HC District enriches the entire community. The scale and density of the buildings, architectural styles, relationship of buildings with open areas, mature landscaping, and residential continuity of the area contribute considerably to the City's unique small town character, and help to mark Claremont as a distinctive place. The district provides a sense of history by evoking early stages of the City's history.
No building, structure, or land shall be used, and no building or structure shall be erected or altered in the HC District, except in accordance with the provisions of this chapter. Non-residential uses, housing facilities of a commercial nature, educational and non-profit institutional uses, and parking lots are incompatible with the HC District, and shall be prohibited uses as specified in this chapter. In addition, all new construction, exterior modifications, and site changes shall be subject to architectural review pursuant to Chapter 16.300.

Such uses or development may be continued, rehabilitated and reconstructed subject only to architectural review pursuant to Chapter 16.300, provided there is no intensification of use and any reconstruction of structures duplicates the size, location and footprint of the destroyed structures.
