Insulation
vapor barrier
The NC Building Code Council has approved the removal of the interior
vapor barrier in most of the State. This code change can now be
accepted in Mecklenburg County which will no longer require the
installation of a paper face product or 4 mil poly coverage on wall
cavities.

Code Update
Final enforcement date for the next residential Code change is
scheduled for June 1st, 2006. With this the requirement for Low E
glazing will be required (SHGC).
•
NC Code Commentary-work will begin on developing a Code
Commentary (State residential Ad Hoc Committee) that
•
•
•
explains/illustrates many sections of the code to help with
interpretations and Code intent. Work will begin in October on
the 1st NC version of a commentary and hope to have out with
the Code change next year.
Deck Code appendix M-Cantilever section of the code has been
changed as far as item #9. There is a new cantilever section in
chapter 5 of the Code that will allow for 2x8 and other lengths of
cantilevered floor systems. This will also be allowed to be used
when building decks.
Table 602.10.5- Committee moved to keep this table as it relates
to a single wall line the same as is currently used. New version
of the Code had language that if you could not get your bracing
like at garage lugs then you could use this table only if you
completely sheathed the entire house with OSB/plywood.
Currently it looked at as only that braced wall line has to be all
plywood/OSB.
Appendix P cantilevers has been deleted completely in 2006
Code.
Closed crawl
spaces
Closed crawl spaces are currently being installed and are permitted now;
see Code changes on DOI website for the September 2004 building
Code council minutes. The issue that has recently come up is that this is
being installed way too early. A sealed crawl space cannot have walls
and floor covered before the foundation inspection has passed. It also is
not practical to have the floor covered until after frame due to the
likelihood that liner will trap moisture under the house (house not dried
in) and that trades may damage liner. Foundations that are covered over,
meaning poly and foam on walls, prior to foundation inspection will be
turned down.
CPCC Code
change training
Discussed efforts to put together a 1/2 day training class on just dealing
with the Code changes in the 2006 NC Code. Intent is to have
something available to builders through CPCC that can be taught on
campus or at builder’s offices and be ready by March of 2006. Will let
builders know once this course has been set up.
Question raised about porch suspended slabs and if inspection is
required. General rule is if space under the slab can be seen at a later
time like at final with crawl access then not generally required. If
suspended slab well area cannot be seen then it should be checked prior
to concrete placement.
This question was asked as a follow up to the effective date of any
Code change and the issue date of the permit applies to the code being
enforced at that time. Question presented to mechanical and they will
require 13 SEER system on any permits issued after January 1, 2006.
