Building attachments such as porches, balconies, and stoops infuse neighborhoods with activity and movement. To incentivize these, codes should permit these attachments to be constructed within the setback zones, where they may be considered a bonus to the building.
Awnings and arcades on commercial building afford a dual benefit: providing shade for shoppers and increasing the physical presence of the shop. These should be constructed over the public sidewalk. Many codes will have to be modified to allow a true arcade, which puts livable area above the public right-of-way and fully shades and protects the sidewalk.
