Wisconsin 21-Day Security Deposit Rule

If the tenancy ends normally, Wisconsin generally gives the landlord 21 days after the end of the rental agreement to return the deposit less lawful withholdings. If the tenant leaves before the agreement ends, an earlier re-rental can move the trigger forward.

DATCP explains that the clock can run from the end of the agreement or the date a new tenant moves in, whichever comes first.

Do not assume “key return date” is always the deadline trigger

An early surrender can leave the rental agreement running. Preserve the lease end date and any proof that a replacement tenant moved in, because those facts can control the 21-day calculation.

Check the exact trigger and charge type. Wisconsin’s 21-day rule can work differently after early move-out, and routine turnover cleaning should not be confused with tenant-caused damage. Educational information only.
