Sewer clean outs required?

[Alan Mills]

Got an inspection objection back with something I’ve not seen on my other rehab’s (this is a Colorado property):

“The seller agrees to have a licensed plumber install external sewer cleanouts per city code and scope the sewer line ensuring its integrity.”

This was a full interior/gut rehab and almost everything is brand new. Yes, sewer clean outs are required on new construction, but on a 1947 rehab house that didn’t have existing clean outs, is it really possible that I can be required to install them? Yes, I’ll check with regional building, but curious for additional thoughts here.

The code being cited by the inspector is below if you care to bother.

Thank you.
