The claim: South Carolina law requires an ESA letter to be renewed annually.
The reality: it does not. The South Carolina Fair Housing Law sets no validity period and no state agency registers or dates these letters. The annual convention comes from housing providers.
The sensible reply: “There is no statutory expiry date, but I am happy to provide current documentation. Attached is a letter dated [date] from [clinician], licensed in South Carolina, with a verification contact.”
Why concede the point: because arguing that a three-year-old letter must be accepted wins the principle and loses the tenancy. Providing something current costs a review and ends the conversation immediately.
