Prerequisites match in two sources for all levels. Clinic stars are a hidden extra condition that only one source lists, so check the upgrade window in game.

Frequently asked questions
What do I need for Sanctuary 30?
Research Lab 29, Training Grounds 29 and Antitoxin Workshop 15, plus the clinic stars the game asks for.
Why is my Sanctuary upgrade locked?
Usually the Research Lab is one level short, or clinic stars are missing. Both show in the upgrade window.
What hero level does each Sanctuary allow?
15 at Sanctuary 4, 25 at 5, then 5 more per level, so 100 at 20 and 150 at 30.
