Sec. 20.712.005 - Intent.¶
The purpose of this Chapter is to provide minimum standards to safeguard life, health, property and public welfare and to promote traffic safety by controlling the design, quality of materials, construction, illumination, size, location and maintenance of signs and sign structures. These standards are a regulation for both applicants and the Mendocino Historical Review Board (MHRB) members to encourage signs that are of a quality design, pleasing in appearance and appropriate in size, materials and illumination to the activity to which they pertain. Further, these regulations are intended to encourage signs which are compatible with the architectural style, characteristics and scale which are historically appropriate as well as being compatible with the building to which they are attached and adjacent buildings and businesses. It is intended that these regulations will enhance overall property values and the visual environment by discouraging signs which contribute to visual clutter such as offsite signs, oversized signs, neon signs and excessive temporary signing. It is intended that commercial signs be designed for the purpose of identifying a business in a functional and attractive manner rather than to serve as general advertising for the business.

(K) The total permissible sign area for each home occupation and cottage industry shall be two (2) square feet.
