doesn't look like it...maybe it's a slither space?

It's not a "crawl" space until it is 4'. 18" and slither work for me, which is about what we have here.

Another correction involved headroom to clean-outs of which there were three located in the underfloor area. I asked for a 30"wide, 30" high clear space from the access to in front of the clean-outs. The clean-outs have been relocated out of the underfloor area.

I probably shouldn't have mentioned this because it may not be part of a code. If that's the case, let me say in advance that I'm not even a little bit surprised nor am I sorry.

IRC 3005.2.5 Accessibility 18 inches in front of clean out

I'm not so sure that will work in California.

And A day later I looked at the code that does work in California.

Here it is:

707.9 Each cleanout in piping two (2) inches (50 mm) or less in size shall be so installed that there is a clearance of not lessthan twelve (12) inches (305 mm) in front of the cleanout. Cleanouts in piping exceeding two (2) inches (50 mm) shall

have a clearance of not less than eighteen (18) inches (457mm) in front of the cleanout. Cleanouts in under-floor piping shall

be extended to or above the finished floor or shall be extended outside the building when there is less than eighteen (18) inches

(457 mm) vertical overall, allowing for obstructions such as ducts, beams, and piping, and thirty (30) inches of (762 mm)

horizontal clearance from the means of access to such cleanout. No under-floor cleanout shall be located exceeding twenty (20)

feet (6,096 mm) from an access door, trap door, or crawl hole.

The only 30" dimension is horizontal. The code even allows for "obstructions such as ducts, beams, and piping" so ultimately the vertical clearance could be zero with zilch for access to the cleanout.

Well I was halfway correct. If we leave the vertical clearance at 18", the job is halfway correct. I think the better outcome is if I'm halfway correct. And that's OK with me because I really don't mind being half wrong....now entirely wrong is another thing.
