Morning all,
I’m working on a code footprint for a wood stake factory (think wood building layout stakes). Currently calling the 7,500 s.f. building F-1/S-1 non separated non sprinklered type VB (IBC 2018). Calling it VB because of some of the wood infill walls -even though it is a PEMB (pre engineered metal building Type II-B)
Question 1 on sprinks 903.2.4.1. “Woodworking operations” says that you have to sprink any area over 2500s.f that generates “finely divided combustible waste”. Is...
This is the definition in Florida. Does it match up with the definition in your state?
CHANGE OF OCCUPANCY. Either of the following shall be considered as a change of occupancy where this code requires a greater degree of safety, accessibility, structural strength, fire protection, means of egress, ventilation or sanitation than is existing in the current building or structure:
1.Any change in the occupancy classification of a building or structure.
2.Any change in the purpose of, or a...
Hi all!
I have looked for the answer here and in the IBC but I'm coming up empty.
I am laying out workstations in a large open room. One end of these cubes will form a 'path' to the exit access doorway. I have always assumed that it needs to be 44" and done it this way (although in this particular case, 36" will do -but I don't use it because it's too tight regardless of what the code says about min. OL)
Long story short, I was just told by a colleague that if the end panels are less than...
How do we classify mechanical rooms when they support an open air A-5 occupancy such as a splish splash park, or a padel court for purposes of specifying fire alarm, fire suppression, emergency lighting, signage etc?
Group U maybe? S-2?
Going with Group U practically exempts these areas from all requirements. Not even emergency lighting....
I have asked a a similar question in an older thread here but the subject was different and the question is not really visible, sorry for repeating...
Working on a project where we have intermediate elevator rail support steel that is inside an elevator shaft wall framed with studs and sheathing.
Is it acceptable for elevator guide rail support steel to interrupt a 2-hour rated elevator shaft wall assembly made of metal studs and two layers of gypsum board in a four-story, steel-framed Type 1B building?
If the steel is exposed in the shaft, does it need to be fireproofed? My colleague is suggesting intumescent paint is required and I...
I am working on a project for a local Co-op and am seeking guidance or thoughts on the appropriate occupancy classification. Obviously, I can run this by the local AHJ, but thought I'd start here, in this forum.
Adopted Codes: 2021 IBC, 2021 IFC
Construction Type: IIB
Fire Protection: To be Determined according to need.
The building in question is a simple (enclosed) PEMB structure with two bays and two sectional overhead doors on both ends, allowing trucks to pull in and drive through...
Hey all,
I am working on a 105,000 sf building of type IIB construction. The building had a change of occupancy/use about 6 years ago from Business / Storage 1 to A3 because a large gun range took over 65,000 sf. The previous architect classified it as A3 unlimited at that time. I'm looking over the code for A3 unlimited area buildings, but I don't see any mention of mixed use with A3. At the time the rest of the building remained S1/B. Is this combination of uses actually permitted...
I recently saw this detail for an new apartment project - -it's the wall between the unit and the corridor, so it's one hour rated and also STC 50+ sound rated.
The corridors are open near the ends and so it is unconditioned, but these walls are far within the corridor and not directly exposed to rain.
Why would there be tyvek on the warm / interior face of stud, underneath the resilient channels? Is it some kind of thermal bridging thing?
2 part question. This is a generic scenario in the attached sketch. No need to overthink.
1. A meeting room requires 2 exits. It has an adjacent small closet (or office or toilet or whatever) that on its own would require 1 exit access. What is the correct way to measure the 1007.1.1 diagonal: red dashed line or blue dashed line?
2. What is the correct way to measure the distance between exits to comply with 1007.1.1.1.1: Thin green line representing the closest opening edges, thin...
We are proposing a space underneath 5 stories of IIIB residential construction. Due to grades and cost of backfilling, we are proposing to basically create a building on "stilts" but surrounded with walls (a crawl space if you will). The next story up (level 2) will connect to the building at the level. It's rather confusing but look at my previous post to see the layout.
Now, we will consider this a story and provide a 3-hr horizontal separation of IA construction. However, we want to...
We have a project for which we have approved the plans, but we can't issue the permit because the engineer (from another state) can't seem to figure out how to complete a statement of special inspections. Last Friday I had a long telephone discussion with the contractor, who is also the applicant, explaining what the issues are. About an hour later, I received a phone call from the owner of named testing laboratory asking why we had rejected them as the special inspections agency. I told him...

This is a general question.
I am looking at a Historic Building project.
This is a 100.000 sqft Museum which will undergo Level 3 Alteration and an addition of another 200.000 sqft area.
The addition will be a basement of sorts.
Which ICC codes would apply? I am thinking IEBC for the existing part and IBC for the addition, but some questions arise.
If the IBC requirements for addition lead to a significantly different architectural and aesthetic approach, what do we do? How do we...
In California, are there any requirements to have an electrical room be fire rated in a single-story medical office building?
The entire building is occupied by a single tenant. Construction is V-B, Group B occupancy for the whole building. The electrical room is accessed from the exterior and is small compared to the rest of the building (less than 5% of the entire building area). There's a few electrical panels, a transformer (which should meet the exception in CEC 450.21), a switchboard...
Newbie here, trying to muddle my way through the code on my own before I present it to a lead. I have a 99,628 bakery addition which I have assigned an F-1 occupancy to. When I did my occupant load the first time around I used "group h-5 fabrication and manufacturing areas" with 200 sf allowance. Now I'm questioning myself if it meant "group h-5 manufacturing" or just "manufacturing". After a look in here, I think I was wrong and should have used "industrial" with 100 sf allowance. So this...
Howdy!
I have a car dealership project with a service drive canopy attached to the service building on one side, then open on the other 3 sides. The sales building is ~5' from the opposite side of the canopy. We have confirmed the canopy complies with Section 3105. The AHJ is contending this canopy is an extension of the service building and we must "demonstrate compliance with Section 705.3". I do not consider this as a reasonable intepretation of the code. There are no walls to the canopy...

Is a warehouse overhead door dock seal governed by the IBC as an Exterior Wall Projection or Combustible Materials on the Exterior Side of Exterior Walls?
705.2 Projections. Cornices, eave overhangs, exterior balconies and similar projections extending beyond the exterior wall shall conform to the requirements of this section and Section 1405. Exterior egress balconies and exterior exit stairways and ramps shall comply with Sections 1021 and 1027, respectively. Projections...
I had an internal code review of a project and there was a comment on an exterior ramp that is part of the Exit Discharge route noting that we needed to provide 10' between the property line and the edge of our ramp and 10' between the ramp and our building per the 2021 edition of the IBC Chapter 10 Exterior Exit Stairways and Ramps Section 1027.5. My understanding is that this section of the code is in reference to stairs and ramps that are Exit Components ie "That portion of the egress...
A building that I am working on has an existing mezzanine that was permitted. The mezzanine is used only for storage. The existing common path of travel exceeds 100'. Are there any exceptions in the code that allow the common path of travel to be disregarded for storage mezzanines? I understand that for equipment and mechanical platforms that the common path of travel does not apply. Does this also include storage mezzanines? Also, if the mezzanine was previously permitted and approved...
at my current job, we do commercial work in restaurants. We've had a discussion at my office concerning the requirements of draft curtains. I was told that they are only required in NYC. This is usually behind the front counter and are used to mount the menuboard on. Sometimes in a remodel of the store we have to modify this. In NYC we have to make sure it matches the existing construction which in NYC is usually onw or 2 layers of gyp board. We had a discussion about if this is required...
In Type I or II construction, other than a plenum space, what are the limitations of using PVC or PEX in Type I or II buildings?
IBC 2018 - 2902.5 Drinking Fountain Location
Drinking fountains shall not be required to be located in individual tenant spaces provided that public drinking fountains are located within a distance of travel of 500 feet (152 m) of the most remote location in the tenant space and not more than one story above or below the tenant space. Where the tenant space is in a covered or open mall, such distance shall not exceed 300 feet (91 440 mm). Drinking fountains shall be located on an accessible...
I have a client that wants to use a wood "pergola like" element suspended by airplane cable or threaded rod over areas of a retail space. I am trying to determine where this falls in the code to provide their millworker with direction on the flame spread and other code requirements. They intend to do this in various locations throughout the country, so I don't have a specific version of the code that I will reference. In some cases this will be suspended below a ceiling and other times it...
I am working on an existing landmarked building from the 50's that is being converted into a Daycare facility. The distance between the building and the property line to the north is 17'-8". There are several doors that egress through this Yard/Egress Court.

Where an egress court serving a building or portion thereof is less than 10 feet (3048 mm) in width, the egress court walls shall have not less than 1-hour fire-resistance-rated construction for a distance of 10 feet (3048...
