Can a Consent of Owner be included on a job sheet or does it have to be on a separate paper?
The langauge under §429.013 governing the Consent of Owner form, reads:
Such consent shall be printed in ten point bold font and signed separately from the notice required by section 429.012...
It appears that the best practice is to provide this form separately and kept for your records once signed. You can download a free MO Consent of Owner Form here to use.
