Wisconsin Landlord-Tenant Laws
Wisconsin Security deposits
Wisconsin sets no cap on residential security deposits, but the landlord must return the deposit within 21 days — with a written statement itemizing every amount withheld — and a violation exposes the landlord to double damages plus attorney fees.
Wisconsin Rent increase notice
Wisconsin has no statute requiring advance notice of a rent increase — the 28-day figure commonly quoted for month-to-month tenancies is derived from Wis.
Wisconsin Late fees
Wisconsin puts no dollar or percentage cap on residential late fees and mandates no grace period, but a landlord may charge a late fee only if the rental agreement specifically provides for it.
Wisconsin Entry notice
Wisconsin landlords must give at least 12 hours' advance notice before entering a rental unit, may enter only at reasonable times, and only to inspect, make repairs, or show the unit to prospective tenants or purchasers — unless the tenant agrees to shorter notice, requests or consents to the entry, a health or safety emergency exists, or the tenant is absent and entry is reasonably necessary to protect the premises from damage.
How this record was verified: Direct read of statute and administrative code text on the official Wisconsin Legislature site (docs.legis.wisconsin.gov, which officially hosts both Wis. Stats. and Wis. Admin. Code): Wis. Stat. 704.28, 704.05(2), 704.19, and Wis. Admin. Code ATCP 134.06 and ATCP 134.09 each read TWICE via independent fetches of alternate stable deep links — all load-bearing figures (21-day deposit return and its three trigger events, 12-hour entry notice, 28-day periodic-tenancy termination notice, 7-day check-in window, the three late-fee paragraphs of ATCP 134.09(8)) matched verbatim across both reads. Also read in full once: Wis. Stat. 100.20(5), 704.95, 704.44, 704.45, 704.08, 704.10, 704.17(1g), 66.1015, 66.0104, and ATCP 134.01/134.02(11) (scope and 'security deposit' definition). Pending-bill statuses checked on docs.legis.wisconsin.gov 2026-07-09: the 2025-26 Legislature adjourned sine die and all landlord-tenant bills (AB 1064 application fees, AB 1048 repeal of 66.0104) failed to pass pursuant to Senate Joint Resolution 1 on 2026-03-23; AB 202 (Wisconsin Consumer Act exemption / void-lease remedy rewrite) passed both houses but was VETOED, so no 2025-26 enactment changes any field.
