GIR, quickly, ride the pig!
Yaaaaaay! I don't know what you just said!
That is correct. From page 8 in the rules, the italicized writing under "Zoning Restrictions":
Buildings “placed” or “moved” via card effect also ignore zoning restrictions.
Ah, perfect! I had completely passed over that when the italicized part started by mentioning parks. It's nice to at least have something to point to to say we've been doing it right.
