Tread nosing
on 11” depth
treads
Issue brought up about the requirement for a nosing on a set of steps if
the steps had at least an 11 inch tread depth. On stone steps there is a
problem associated with steps having a small amount of nosing while
others are flush. Issue was discussed and a formal interpretation was
issued based upon the new code but application can still be used under
the 2002 Code since there were no changes in tread requirements. See
interpretation attached to minutes.
Anchor bolt
requirement
change for
townhouses
There is a new requirement for interior bearing walls on townhouses to
be anchored with standard ½” anchor bolt in Seismic design category C
which is our area. This requirement also has a much larger washer
specified in R602.11.1, this washer size is required on all bolts, exterior
or interior. Anchor straps used on townhouse will have to be by
engineering design based upon equivalent holding capacity.

requirements
Issue brought up about the exception that was allowed under the 2002
Residential Code, section R315.2, which is no longer in the 2006 Code.
This will prevent builders from using 2x4 railings on porches and decks
and a graspable type 1 or type 2 handrail as listed in the 2006 code will
need to be provided on structures permitted after January 1st, 2006. The
BCC is currently trying to getting an amendment approved to allow at
specific exterior locations the use of a 2x4 rail but currently has not
passed.
The Department is still moving toward plan review on all residential
new structures and will look at doing so once staff is in place to handle
loads in a timely manner. Currently projecting no earlier than March of
’08 but may be later.
There are several significant changes dealing with retaining walls (see
section R404.1.3, page 59 of the 2006 Code). Based upon new language
in the Code retaining walls that cross property lines and those that have
more than 48” of backfill against them anywhere on a residential lot will
be required to have an engineering design and permit. This retaining
wall can be pulled with the house and needs to be noted on the
application that retaining wall is included in construction cost or a
separate permit for retaining wall only can be pulled. The question that
came up during the meeting was how the Department will inspect these
retaining walls. The only wall that will need to be called in and checked
by an inspector will be the poured concrete foundation walls. Other
retaining wall systems like keystone blocks will need to be reviewed by
an engineer and a final sign off letter provided to the Code official and
final stating that the wall was installed per provided engineering plans.
So at final both the plans and sign off letter will be needed on
everything but poured in place concrete wall system.
Question asked about weep hole requirements and are they needed over
window and door openings regardless of opening width. Per NCDOI all
flashing lines will have to have at least 1 weep hole, example being if
you have a 2/0 window you must have 1 weep hole, best location is
centered on the opening. Code references are R703.7.5 and R703.7.6.

Tread nosing requirements
Reviewed by: 101, 139 & 147
Questions:
1. If a flight of stairs has a uniformed tread depth of 11” is a nosing required?
2. If a nosing is provided on an 11” tread depth stair are they required to be
uniformed?
Code reference: R311.5.3.3
ANSWER:
No to both questions. Exception #1 under R311.5.3.3 states that a nosing is not required
if an 11 inch tread depth is met. If in a flight of stairs there is a uniformed 11 inch depth
measured at the treads leading edges then no uniformed nosing is required. In this case,
as pictured below, treads could have a variety of nosing and no nosing application as
found on some stone steps as long as uniformity of the tread was maintained and depth
was enough to meet the requirements of exception #1. The structural support capacity of
any such nosing projection must be taken into account.
