Secondary Structure Design
Secondary structures, such as detached garages, sheds and studio
spaces, provide important spaces for many properties. They
should generally be subordinate to the primary structure in design
and visibility. When visible from the public realm, a secondary
structure in a traditional neighborhood should be visually
compatible in overall form with the primary structure. Where a
secondary structure is located near a shared rear or side lot line, it
should minimize impacts on neighboring properties. Illustrations
