All signs affixed to a building or structure shall be regulated
as follows:
A. General building sign regulations.
(1) A building sign shall not project horizontally more than five feet
from the wall of a building or side of a structure.
(2) A building sign shall not project vertically above the top of a building,
structure wall or parapet. A building sign is also permitted on the
roof of a building or structure only if such sign does not project
vertically above the roofline of a building or structure. See Figure
10 for examples.
Figure 10. The top image would be permitted as a roof sign that
does not extend above the highest point of the roof. The bottom image
would not be permitted as the sign extends above the highest point
of the roof.
|
(3) No building sign shall be closer than two feet to the right-of-way
line.
(4) Any building sign which extends laterally from a building wall above
a sidewalk or similar pedestrian/bicycle facility by more than 12
inches shall have a clearance of at least eight feet below a building
sign.
(5) Any building sign located above a driving surface shall have a minimum
clearance of 16 feet.
B. Sign area. All building signs shall be restricted in terms of area,
as noted below including an overall sign area for all signs as follows:
(1) No sign which projects more than 12 inches horizontally from the
wall of a building or structure shall have a sign area greater than
15 square feet if single-faced or 30 square feet if double-faced.
(2) Any sign located on the roof of a building or structure as permitted in §
170-11A(2) shall not be permitted to have a sign area greater than 32 square feet if single-faced or 64 square feet if double-faced.
(3) All other building signs shall have no restrictions in terms of number given that the total area of all building signs do not exceed the total permissible sign area pursuant to §
170-11C.
C. Total permissible sign area. The total sum of the area of all signs affixed to a building except those exempted pursuant to §
170-8, Exempted signs, shall be calculated as follows:
(1) Calculating the total permissible sign area of building signs shall
be done based on the gross floor area (GFA) of either the entire building
or individual tenant spaces using the following methods:
(a)
Single-tenant building. Permissible sign area shall be based
on the GFA of the entire structure.
(b)
Multitenant building.
[1]
For multitenant buildings in which all tenants have their own
external entrance available for use by the general public, the total
permissible sign area shall be based on the GFA of the individual
tenant space.
[2]
If a multitenant building has a mixture of tenants with their
own external entrances available for use by the general public and
tenants that do not, the total permissible sign area shall be calculated
based on the GFA of each individual tenant space with their own external
entrances plus the total calculated permissible sign area calculated
on the GFA of the remainder of the building.
(c)
Multibuilding lot. Gross floor area shall be measured for each
building on a given lot separately utilizing one of the two appropriate
methods above.
(2) The total permissible sign area for all building signs that are not exempt pursuant to §
170-8, Exempted signs, or located in the Planned Research and Business Park District or the Medical Campus District shall be calculated based on the GFA as noted above utilizing the following formula.

(4) Number of. The number of building signs shall not be limited given that the area of all building signs meet the total permissible sign area standards as noted in §
170-11C above or except as follows:
(a)
There shall be no more than one sign that extends horizontally from the wall of a building or structure as permitted in §
170-11A(1). If the building is a multiple-tenant building, then there shall be no more than one building sign that extends horizontally from the wall per tenant.
(b)
There shall be no more than one sign that extends vertically above the wall of a building or structure as permitted in §
170-11A(2). If the building is a multiple-tenant building then there shall be no more than one building sign vertically above the wall per tenant.
(5) Height. A building sign may be mounted at any elevation on the side
of a building. However, if said sign is mounted to a parapet, it shall
be mounted in a fashion that no portion of such a sign exceeds 25
feet in height as measured from the existing average grade directly
below the sign on said parapet.
(6) Exemptions from sign area calculations. Signs conveying messages
on buildings of importance for the purposes of public health, safety
and welfare shall be exempted, as follows:
(a)
The following words shall be exempt from area calculations of §
170-11:
[1]
"Fire" or "Fire Station."
[2]
"Police" or "Police Station."
[4]
"Emergency" or "Emergency Room."
[6]
Any other similar term or symbol conveying the identification

170-11C.
D. Brightness. All electronic or digital signs shall be equipped with
automatic brightness level controls to reduce light levels at night,
and under cloudy or other darkened conditions in accordance with the
following:
(1) All electronic or digital signs shall have installed ambient light
monitors and shall at all times allow such monitor to automatically
adjust the brightness level of the electronic or digital sign based
on ambient light conditions so as to minimize and keep consistent
sign brightness.
(2) The maximum brightness levels for such signs shall not exceed 5,000
nits when measured from the sign's face at its maximum brightness
during daylight hours.
(3) The maximum brightness levels for such signs shall not exceed 500
nits when measured from the sign's face at its maximum brightness
between sunset and sunrise, as those times are determined by the National
Weather Service.
(4) Written certification from the sign manufacturer must be provided
at time of sign permit application certifying that the light intensity
of the sign has been preset not to exceed the illumination levels
established by this section, and that the preset intensity level is
protected from end user manipulation by an approved method such as
