Residential
V VI VII VIII

ADS 5.11.1 Intent.

In order to visually terminate an exterior wall on a flat-roofed building, a cornice on a parapet wall shall be used. This cornice provides a minimal amount of protection to the wall that a pitched roof overhang would normally provide.

Standard:

ADS 5.11.2 Parapets with a Cornice.

Flat roofs shall incorporate a parapet and cornice into all building fronts. The cornice shall wrap a minimum of four (4) feet around corners. Flat roofs projecting from a building front shall include a cornice around the entire projection.

ADS 5.11.3 Parapets without a Cornice.

Simple parapets with a stone or brick cap without a cornice are allowed on building sides other than a building front.
