Well, I think that the issue will be whether the dog works for the tenant.

Hypothetical situation: I don't have a dog. I build one of these. A tenant signs a lease. Then I get a dog. But the tenant is terrified of dogs. But they've signed a lease, and (because nobody thought it would be an issue) there's nothing in the lease about whether the owner can have a dog. Now the tenant is really stuck - essentially they are at the owner's mercy.

I don't know if your standard agreement covers this situation, but if not, it's something to think about...

In my country (not US) it is by law allowed for either side of the lease to terminate it under extraordinary circumstances.

This situation would certainly fall under that. Obviously, if the other party objects to the termination, you'd need to get some sort of medical verification for your condition.

This is definitely something to think about as we get closer to renting these units. Our expectation is for tenant and homeowner to be fair and reasonable and we're developing a framework for what that looks like.
