In regards to ESAs, the application of law is from the Fair Housing Act which states a "a refusal to make reasonable accommodations in rules, policies, practices, or services, when such accommodations may be necessary to afford such person equal opportunity to use and enjoy a dwelling."

I make sure all of our couches are pullouts, so a 2 bedroom can accommodate 6 or sometimes 8 people.
