BEST PRACTICES FOR ADDITIONS TO CONTRIBUTING HISTORIC BUILDINGS
An addition to a contributing building in a local historic district should be set back from the front facade, be
minimally visible and be designed to be in proportion with the original structure. The models below illustrate a
range of appropriate and inappropriate additions to contributing main buildings.

ONE-STORY, REAR ADDITION
The rear addition illustrated at
right is appropriate because it is
minimally visible from the street
and is subordinate to the original
building.

ONE-STORY REAR ADDITION
WITH CONNECTOR
This rear addition with a connector
is appropriate because its location
makes it minimally visible from the
street. It also uses a connector to
distinguish between the original
structure and the addition.

CAMELBACK ADDITION ON
ONE STORY
This camelback addition is
appropriate because it is set back
to the rear of the original structure
and is kept in proportion with the
original structure.

INAPPROPRIATE CAMELBACK
ADDITION ON ONE-STORY
The addition shown to the right is
inappropriate because even though
it is set back from the front of
the original building, it is out of
scale and overwhelms the original
structure.

INAPPROPRIATE TWO-STORY
ROOFTOP ADDITION
The roof-top addition illustrated
at right is inappropriate because
it substantially alters the primary
facade of the historic building
