add outdoor cleanout or just plan on rodding through toilet

[Kimberly H.]

About to close on a single family home with single bathroom, the plan for it is to be a rental for years.

Would you add an outdoor cleanout, or just plan to rod sewer lines by removing the toilet every time? I've confirmed with a plumber who was at the house that that is how it would be done with no cleanout added.  

There is one arbor vitae close to where I believe the sewer lines run.

Other houses we've rodded already had cleanouts added at some point by previous owners. I've learned that current code is to have an outdoor cleanout, but it's not something that ever comes up with city rental inspections or inspections by home inspectors.
