Multi-tenant buildings shall provide uniform storefronts, doorways, windows, awnings and other design features for all ground floor tenants. Upper floors of said buildings shall at a minimum be coordinated with the ground floor through common materials and colors. Storefronts should include display windows with a sill height not less than two feet from grade.

New construction should use windows of similar sizes and shapes or incorporate other facade elements that establish the same pattern of other buildings in its context. Window and door sizes and shapes should not be significantly altered by any building renovation.

In new construction, dominant zones and horizontal lines that establish those zones should be included in the design. Such lines include the tops of display windows, sign fascias, cornices and belt courses.

Rhythms which carry through a block such as store front patterns, window spacing, entrances, canopies or awnings, etc., should be incorporated into new or renovated facades.

Fire escapes are prohibited on the principal facade of a building.

Facade renovations should be consistent with the original architectural style of the building. Original details should be retained; when it becomes necessary to introduce new features, they should harmonize with existing features. If windows and doors must be replaced, new materials that match the original design should be used.

Surface detailing should be integrated within the structure rather than applied for decorative purposes.

Exterior mounted mechanical and electrical equipment shall be architecturally screened.

The use of creative lighting schemes to highlight building facades and related areas of a site shall be encouraged, except that any such nonresidential lighting shall be shut off by 10:00 p.m. or one-half hour after the closing of such nonresidential use, whichever is earlier.
