8.14.1.2.2 (02 ed) specifically allows LIMITED ACCESS in concealed spaces. It isn't that the space has to be constructed such that you can not get into it, It's what you do with the space with limited access. Thats why the LIMITED ACCESS is followed by NOT permitting occupancy or storage of combustibles.

I have a small non combustible crawlspace below a new 3-story NFPA-13 protected commercial building. There is access via a ships ladder and a small hatch. The height of the crawl space to structure is 2.5 feet, the area is below grade and unheated. Installing a dry system would be a task coordinating around ducts and maintenance would be a nightmare with no floor or exterior drain location.

If there wasn't a hatch it would be a non-combustible concealed space. What is your experience/thoughts with controlling storage administrativly and allowing the space unsprinklered?

Thanks
