Nonaccessible lavatories: minimum spacing in code?

[Yikes]

I need to reconfigure an existing multi-user restroom for ADA. To get more space for ADA fixtures, I need to relocate the non-ADA wall-hung lavs, squishing them together as closely as possible.
In the past, for a 17" wide x 19" deep wall-hung nonaccessible lav, I've typically seen (A) 15" from and adjacent side wall to centerline of lav, and (B) 30" o/c for all other sinks thereafter.
Are either of them CODE minimums, or can I go less than that for either (A) or (B)?

(If they are in a code, please help me find the actual reference. Thanks!)

Thanks, Steve Ray. I just now found it in the California Plumbing Code in 402.5 "Setting". Apparently, CPC is similar, except that it is silent on lavatories, and it lets urinals be closer: 12" to a side wall, and 24" center-to-center.

Set the lav back and you can get your sink and water closet closer. Use a short grab bar behind the water closet. Use a short lav that is wall hung. You only need to fit clear floor space inside the small toilet room.

See CBC 11B vs PC, 18" min. to center for accessible lav & urinal

Thanks everybody, but to repeat, the original question is solely about spacing of NON-ACCESSIBLE lavatories, not accessible fixtures.

Back in the day, 1927' published refs indicated 30" min. for stalls when folks were skinnyer. 1/2 of 30 = 15"

The only thing in the CPC is ..."The clear space in front of a water closet, lavatory, or bidet shall be not less than 24 inches..." So, I read that as 24" wide by 24" deep.

maybe for residential but 11B requires 30 x 48 for lavs and 18" min from adjacent wall.

poster stated "...non-ADA wall-hung lavs..."

Code is not always common sense, or touchy feely....
