In an ideal world, you never have to renumber because your allocations were perfect from the get-go.Depends - If you're an Enterprise where 90% of the equipment is managed by people who work in the same building, it's not horrible. I renumbered a bunch of /20s onto a /18 where 75% of the equipment was not in my (or the company's) control. That sucked big time.
Right, but a /20 is a /lot/ more space than a /24. I think I'd say that shorter than a /21 is certainly a decent threshold of pain (personally). Even if its all in-house.
There are ways to make it less painful and special painless cases (an all NAT space), but as a shot-in-the-dark, that's a pretty good bet [you almost certainly have a decent mix of network and server gear, different authorities, different topologies, etc]
