Hi all, long time lurker, first time poster. I'd love to get anyone's take/advice on how you'd handle a situation with code compliance. I'm new to an office and was asked to help do some field reports for a project far along in CA. I was specifically asked to check the stairs and found one to have landings that were not compliant per Georgia's NFPA 101 7.2.2.3.2.2, stairs and intermediate landings shall continue with no decrease in width along the direction of egress travel. I flagged it along with a number of other deficiencies/observations and moved on with my life (though I admit this issue would be a big cost to fix compared to other items). The construction arm of the business (same firm) first spent a couple weeks under the tact that I must be measuring wrong. Shops had the landing dimensions from inside of stringer to edge of nosing to equal stair width (inside of stringer to inside of stringer.) I've always measured it from wall to inside of guardrail, but I could see inside of stringer to inside of stringer as long as you were consistent with both the stair width and landing measurement.
Q1) how do you guys measure the stairs/landing widths?
Well, eventually everyone seemed to get on the same page and I thought this would go away. Then I got an email from the Arch-side project manager as an FYI forwarding a city office of buildings code official response that I quote:
The below is an elaboration to the stair landing requirements & clarification we discussed this morning & follow up photo documentation.
Although LSC 7.2.2.3.2.4 (cited below) includes the provision that the 48” max dimension in the direction of egress travel is applicable “provided the s the stair has a straight run”, the IBC has no such restriction.
The IBC states, “Every landing shall have a minimum depth (sic) equal to the width of the stairway or 48” whichever is less”.
In this case, the IBC shall prevail due to the rationale spelled out in our discussion.
NFPA-101 (LSC), 7.2.2.3.2.2
Stairs and intermediate landings shall continue with no decrease in width along the direction of egress travel.
7.2.2.3.2.3
In new buildings, every landing shall have a dimension, measured in the direction of travel, that is not less than the width of the stair.
7.2.2.3.2.4
Landings shall not be required to exceed 48 in. (1220 mm) in the direction of travel, provided that the stair has a straight run.
IBC, 1011.6 Stairway Landings
There shall be a floor or landing at the top and bottom of each stairway. The width of landings, measured perpendicularly to the direction of travel, shall be not less than the width of stairways served. Every landing shall have a minimum depth, measured parallel to the direction of travel, equal to the width of the stairway or 48 inches (1219 mm), whichever is less. Doors opening onto a landing shall not reduce the landing to less than one-half the required width. When fully open, the door shall not project more than 7 inches (178 mm) into a landing. Where wheelchair spaces are required on the stairway landing in accordance with Section 1009.6.3, the wheelchair space shall not be located in the required width of the landing and doors shall not swing over the wheelchair spaces.

I am not sure who was in on the conversations above but I have the following issues:
1) IBC is trumped by NFPA in Georgia for egress concerns to my understanding
2) both IBC and NFPA match anyway, landing widths should be the width of the stair, minimum
3) the code official seems to have been confused/misled into understanding the problem as a depth of stair issue and is referencing that part of the code instead of the width of stair
4) Everyone on arch and construction seem to be satisfied with the above email to put the issue to bed without addressing the landings, which if measured either from inside of string to inside of stringer or from wall to inside of guardrail, are less wide than the stairs they serve
Q2) How would have any of you proceeded in situations like these? I feel like if I don't want to drop this, my next step would either be 1) escalate to corporate HQ in-house since the PM is regional level leadership, 2) go to the OoB AHJ official (dep. chief) and point out his errors verbally and see if he wants to address it again, or 3) file something with the fire marshal so that when they do their Cert of Occ inspections they know to catch/flag it
