[Vampires, general] Can my landlord let vampires into my apartment?

Depends often on the lore.

And how the threshold is created (or if it's threshold based)

Typically a threshold is a form of magic from the thought of "home = safe" so anybody who considered the place to be home (or sanctuary) could likely invite the vampire in.

In the case of there being no threshold, then it depends on the legalities of who has permission to let a vampire in.

Usually in that case, anybody currently inside the house can invite in the vampire, but simply owning the building would not be enough.
