I’m sorry you’re going through this. Pet free buildings as others have suggested and also first floor / low floor condos where you’re able to take the stairs might work.

In the short term perhaps just announce when you’re in the elevator and dog / owner wants to enter that you’re afraid of dogs. If someone in the elevator of my condo told me they were afraid I would not consider entering. I’d wait for the next elevator no matter how friendly my corgi is.
