In my experience, we were given the set of covenants when we signed a contract to purchase a home. We had 3 days to fully review and ask any questions about the covenants with the option to back out of the contract during that window. I don’t know if that’s still the case.

That said, it sounds like the fencing for your doggos is a priority. So don’t get hung up on Columbia, check Ellicott City and nearby communities. You might find a more suitable home. Good luck!
