Buildings, structures, and uses existing at the time of passage of this article shall be exempted from required parking. Alterations that do not increase the gross square footage of the building, or the structure existing in the Artisans & Industry Special District are exempt from providing new or additional off-street parking.

Parking or loading spaces existing at the time of passage of this article shall not be eliminated or reduced in number except that the location, size, layout of such existing spaces may be changed in conjunction with site plan review.

New buildings and structures. Parking shall be provided as per the requirements contained in Article X, Off-Street Parking and Loading, for any new buildings, structures or increases in gross square footage of existing buildings.

Certain retail, restaurant, eating and drinking establishment, indoor commercial recreation, health club and gymnasium and personal service uses are permitted in the Artisans and Industry Special District on the ground floor only. The gross square footage of these retail, restaurant, eating and drinking establishment, indoor commercial recreation, health club and gynasium and personal service uses shall not exceed, in total, an area equal to or less than 20% of the gross floor area of the building.

Ground floor. For the purposes of the Artisans and Industry Special District, the term "ground floor" shall mean that story of a building or structure that has direct access from the adjacent street or land. In cases where a building or structure has access on more than one level due to the slope of the land and the construction of the building or structure, the owner may select the floor that will be considered the ground floor for all retail, restaurant, eating and drinking establishment, indoor commercial recreation, health club and gymnasium and personal service uses. Such "ground floor" designation shall apply to all future retail, restaurant, eating and drinking establishment, indoor commercial recreation, health club and gymnasium and personal service uses in the building.

Primary entrance. For the purpose of regulating signage for the certain retail, restaurant, eating and drinking establishment, indoor commercial recreation, health club and gymnasium and personal service uses, a primary entrance to these uses shall be established and designated when the building permit is applied for.

Signage restrictions. Due to the National Register of Historic Places designation of the buildings in the district and the City's interest in preserving the aesthetic resource, signage shall be limited in the following manner.

Retail, restaurant, eating and drinking establishment, indoor commercial recreation, health club and gymnasium and personal service uses. Signage for these uses shall be located at the exterior primary entrance leading directly to the use and shall be located no higher on the building or structure than immediately above the ground floor windows. Such signage shall be sized so as to not cover architectural features of the building including, but not limited to, window sills, window lintels, belt courses, and the like. Signage for retail, restaurant eating and drinking establishment, indoor commercial recreation, health club and gymnasium and personal service uses shall not be permitted elsewhere on the building except as a part of a flush-mounted directory sign no larger than three feet by three feet adjacent to entrances that are not the primary entrance to the use.
