Do ESA Letters Expire? The Renewal Rules, Federal and State
Federal law sets no expiration date for ESA letters, but the working standard is documentation of a current need, and most landlords treat a letter older than 12 months as stale. Several states now add explicit timing rules. The practical answer: renew annually, and always before a move.
The Federal Rule: No Expiration, but a Currency Standard
Nothing in the Fair Housing Act stamps an expiry date on ESA documentation. What landlords and courts look for is reliable documentation of a disability-related need that exists now, the standard HUD's 2020 guidance also articulated. Landlords translate that into a simple screen: is the letter dated within the past year? A fresh date reads as a current need; a three-year-old letter invites questions no tenant wants to answer mid-application.
States That Put Renewal Timing in Statute
- Iowa: the written finding must be made within 12 months of the start of the rental agreement and is valid for 12 months or the lease term, whichever is greater (Iowa Code § 216.8C).
- Arkansas: the provider must complete a clinical evaluation at least once each year and review the need yearly to renew the documentation (Ark. Code Ann. § 20-14-1003).
- California, Montana, Louisiana: the 30-day provider relationship rules apply to issuing documentation, which makes renewing with the same provider the efficient path: the relationship already exists, so no new waiting period starts (California, Montana, Louisiana).
Every state's rules are tracked with citations in the state law hub.
When to Renew
- Annually, on scheduleThe 12-month mark is the standard landlords actually apply. Set the reminder when you get the letter.
- Before any moveA new accommodation request should lead with a current letter, dated within the past year, ideally within the past few months.
- Before lease renewal in a stricter stateWhere statute ties validity to the lease term, renew ahead of the new lease so the paperwork never lapses.
