Chapter 1
Scope and Administration
• Chapter 1 has historically been re-written by Kentucky
so as to address Kentucky specific needs and interests
regarding building construction and code application.
• The 2013 KBC follows the same formatting as the 2012
IBC.
• Many of the KY amendments to Chapter 1 is code text
carried forward from the previous edition and many you
have seen since the1980 edition of the KBC. However,
there are a few new sections we will review.

2007 KBC
2013 KBC
New text added via IBC
• Section 101.3 Purpose
o IBC text was deleted as an
amendment to create this
section in the 2007 edition.
• Section 101.3 Intent.
o The purpose of this code is
to establish the
minimum/maximum
requirements … and safety
to life and property from fire
and other hazards
attributed to the built
environment and to
provide safety to fire
fighters and emergency
responders during
emergency operations.
The underscored language is not new to the code but is new to the KBC.
The 2013 KBC no longer deletes this text. The new language extends the codes intent
beyond that of establishing safeguards for the public and building occupants.
It extends application to the protection of our fire fighters and first responders during
any emergency operation and event.

102.6.1 Moved structures.

this code for new buildings and

apply to manufactured homes.
Exception: Industrialized buildings
moved into or within the

Section 506.2.1
Width Limits
• Revised text and new equation via 2012 IBC added for
clarification
• 506.2.1 Width limits. To apply this section the value of W shall
not be less than 20 feet. Where the value of W varies along
the perimeter of the building, the calculation performed in
accordance with Equation 5-2 shall be based on the
weighted average calculated in accordance with Equation 53 for portions of the exterior perimeter walls where the value of
W is greater than 20 feet…W shall be measured perpendicular
from the face of the building to the closest interior lot line.
Where the building fronts on a public way, the entire width of
the public way shall be used. Where two or more buildings
are on the same lot, W shall be measured from the exterior
face of each building to the opposing exterior face of each
adjacent building, as applicable.
40
Equation 5-3
W=(L1 x w1 + L2 x w2 + L3 x w3 + L4 x w4)/F
• L = length of a portion of exterior perimeter wall
• w = width of open space associated with that
portion of exterior perimeter wall (Remember: must be
greater than 20)
• F = building perimeter that fronts on a public way or
open space having a width of 20’ or more
41
W=(L1 x w1 + L2 x w2 + L3 x w3 + L4 x w4)/F
W = (75 x 30 + 125 x 20 + 75 x 0 + 125 x 30)/325
W = (2250 + 2500 + 0 + 3750)/325

Where does “W = 26.15 “ go?
