ESA letters in Wisconsin
Your core right (federal law)
The federal Fair Housing Act requires most landlords to make a reasonable accommodation for an emotional support animal, even under a "no pets" policy, once you have a legitimate letter from a licensed clinician. This right comes from federal law and applies the same way in Wisconsin as anywhere else in the US.
No extra waiting period
Wisconsin doesn't add the extended clinician-relationship requirement that a handful of other states do. A single consultation is enough for your clinician to make a determination.
Air travel: a note
Since a 2021 Department of Transportation rule change, airlines are no longer required to accommodate emotional support animals the way they once were, and they can treat an ESA as a regular pet, subject to pet fees and carrier policies. An ESA letter's strongest, most reliable protection today is housing, not air travel. We'd rather tell you this upfront than let a letter imply a guarantee it can't back up.
