Topics/Subject Decisions/Conclusions/Actions Old Business None New Business Ice shield protection requirement New guard detail on open side of stairs This requirement has been added to table R301.2(1) and in the discussion about the application of this section, also listed under R905.2.7.1, it was determine there were no figures given to indicate the average January temperature nor is there a source referenced in the Code to verify an area’s weather conditions by. The National weather service is the best source of information in determining an area’s average temperature for January. The NWS gives a 30 year high and low history and based upon that information the average temperature in January for Charlotte is 41 degrees. The Ice shield protection will not be required for this area, see NWS handout attached. Passed out detail from NC Code commentary and 2006 Code text that shows a new requirement for guards on open side of stairs. In the past a handrail on the open side of the stairs could be used as a guardrail/handrail combo at a mounting height of 30”-38”. Still can use as a guardrail/handrail combo but new Code requires standard IRC mounting height of 34”-38” which means some builders will need to raise their mounting heights on open side of stairs, see section R312.1. The other issue is also on open side of stairs dealing with guard opening limitations per section R312.2. Exception #2 will allow for a guard opening on the side of stairs that will not allow a 4 3/8” sphere to pass through, depending on the baluster or picket this may require 3 balusters at each tread instead of two. Issue is being addressed at the State level due to the fact there appears to be a conflict between the text and the Under stair protection exception. Code allows 6” on open side of stairs and exception reduces back down to 4 3/8” on open side of stairs. Attached to the minutes is a copy of the handout. The requirement for under stair protection was left out of the code and was actually mistakenly deleted in section R311.2.2. Since it was approved like that it cannot currently be enforced. The BCC however is placing back in the 2009 code and it should be required again under the next Code currently scheduled to be mandatory on January 1st, 2009. March 3rd 2008 full plan review & retaining walls Discuss the effective date for full plan review on all new residential homes and footprint additions which is March 3rd 2008. Retaining walls required to have a permit will also have to be submitted for plan review which will require an engineering plan on wall installation. Field staff will currently only look at poured concrete retaining wall systems all others will require engineer to verify installation and sign off letter at final. Energy star homes There was a question asked from several builders that are going to an energy star home program. In so doing several areas of the home like behind the fireplace and tub areas will be encapsulated with an interior wall covering. Issue of concern is how will frame and insulation be inspected for these areas when they will be covered up at frame check. Issue will be discussed with building staff and brought back to next consistency team meeting to determine how to handle. Exterior exit door requirements Question came up about size requirement for exterior egress door that is not the 1 required exit door as listed under section R311.4.1 & R311.4.2. If another door is installed in addition to the 3/0x6/8 is there any requirement under the code that additional doors meet a certain door size. Under section R311.4.2 the last sentence states that other doors shall not be required to comply with these minimum dimensions. Based upon the language listed under this section we would not regulate other door sizes installed on the exterior of a home. Brick veneer up roof lines Issue discussed about how to support brick veneer up rake climb, currently both sections dealing with this application have changed somewhat under section R703.7.2.1 there is a specific requirement for lag screws to be used and lintel to support veneer to wall framing. This requires screws at double stud’s 16”o.c. or single studs with solid blocking between studs. It is important to make sure screws are into support framing and not just sheathing but this is not a bolt on lintel and not required to be up at sheathing inspection. The second option is supporting lintel on roof. What changed under this section R703.7.2.2 is that support members must be tripled rather than doubled under previous code. Neither application is required to be up at frame or sheathing inspection.
