21 days after the tenancy ends
Wisconsin does not cap how large a residential security deposit may be. Unused deposit plus an itemized list is generally due within 21 days (Wis. Stat. § 704.28). If you never gave a move-in checklist, you generally cannot deduct for pre-existing damage (ATCP 134).
A month-to-month tenancy generally takes at least 28 days’ written notice (Wis. Stat. § 704.19).
Except in an emergency, the landlord must give advance notice. Twelve hours is the usual statutory standard (Wis. Stat. § 704.05).
A Wisconsin rent increase should be in writing. Many landlords use at least the same notice they would use to end a month-to-month tenancy. A month-to-month tenancy generally takes at least 28 days’ written notice (Wis. Stat. § 704.19). The lease may require more. Local rent-control rules can cap the amount even when the notice period is met.
Wisconsin residential leases commonly need these statewide disclosures. The lease generator adds them when your answers trigger them.
ATCP 134 disclosures
Wisconsin’s residential rental practices rule requires specific disclosures, a check-in sheet, and limits on certain fees. Statewide clauses are not a substitute for the ATCP 134 packet.
