minimum closet depth

Our remodel now has finished walls, flooring , cabinets and custom closets are next. I just went to measure and although the plans say the closets are to be 2' deep... they are only 22".

Everything I read says minimum depth should be 2'...

What to do now?

Is this going to be an issue, should I work with builder to get it fixed or is it not that big of a deal.

Our guest closet and coat closet are deep. Master has a small walk in... So it's just teen daughter's closet and 2nd bedroom closet .

Any suggestions?
