Wisconsin compliance obligations

Wisconsin landlords commonly track 6 state and local compliance obligations, each listed below with its schedule, its sources, and the date we last verified it. Among them: confirm local rental contact registration requirements, file Wisconsin LLC annual report by your formation quarter's end, and pay property tax in full or first installment by January 31.

Confirm local rental contact registration requirements

Wisconsin law bars cities, villages, towns, and counties from requiring rental licenses or certificates, but a local government may require a simple registration naming one owner or contact person with an address, phone number, and email, so check whether yours does and update the filing whenever ownership, management, or contact details change, which keeps code and inspection notices reaching you.

File Wisconsin LLC annual report by your formation quarter's end

Wisconsin LLCs must file an annual report with the Department of Financial Institutions each year by the end of the calendar quarter containing the formation anniversary ($25 online, $40 by paper), and an LLC that falls behind is marked delinquent and, after notice, can be administratively dissolved.

Pay property tax in full or first installment by January 31

Wisconsin real property tax is due January 31, either in full or as the first installment (a bill under $100 must be paid in full), and missing it makes the whole year's unpaid tax delinquent as of February 1, with 1 percent monthly interest plus any local penalty of up to 0.5 percent a month.

Pay the final property tax installment by July 31

If you paid your Wisconsin property tax bill in installments, the last installment is due by July 31 to the treasurer named on your bill (some municipalities set extra or later installment dates, so check it), and missing it makes the whole unpaid balance delinquent with 1 percent monthly interest plus up to 0.5 percent monthly local penalty, charged back to February 1.

Return security deposit with itemized statement within 21 days of move-out

Wisconsin law (ATCP 134.06) requires delivering or mailing the deposit balance, less any properly withheld amounts, and a written statement explaining any withholding within 21 days after the tenancy ends, and noncompliance exposes the landlord to double damages plus attorney fees.

Test smoke and carbon monoxide detectors and log maintenance

Wisconsin owners must install smoke detectors and, where the home or building has a fuel-burning appliance, fireplace, or attached garage, carbon monoxide detectors, must maintain the common-area smoke detectors and every CO detector in buildings of 3 or more units, and must fix a unit's detector within 5 days of a tenant's written notice that it is not working, so a documented annual test keeps you compliant and defensible.

Seasonal maintenance for Wisconsin

Landlords in Wisconsin plan upkeep around a cold climate: this guide lists 7 seasonal maintenance items for Wisconsin in calendar order, each with its timing and the date we last verified it. Among them: inspect roof, foundation, and test sump pumps at spring thaw, smoke and CO detector seasonal test, and winterize exterior plumbing and irrigation before first freeze.

Inspect roof, foundation, and test sump pumps at spring thaw

Snow cover in southern Wisconsin usually lasts only part of March and in the north lingers into April, while precipitation climbs from about 2 inches in March to about 3 to 4 inches in April, so a mid-March sump pump test, with a roof and foundation check once the snow is off, catches a failed pump or winter damage before meltwater and spring rain turn it into a flooded basement or a ceiling leak.

Smoke and CO detector seasonal test

An annual full test of smoke and CO detectors (beyond battery swaps) confirms every alarm actually sounds.

Get snow removal contract quotes before contractors book up

Reliable snow contractors fill their schedules early and offer better rates before the season, and Wisconsin cities, villages, and towns can fine owners or occupants who leave public sidewalks uncleared, so gathering quotes in mid-August lines up a dependable provider before the first inch of snow, which typically falls around November 1 in the far north and in late November or early December in the south.

Winterize exterior plumbing and irrigation before first freeze

Median first freezes arrive in the last week of September across inland northern Wisconsin, in early to mid October across central and inland southern Wisconsin, and in late October along the southern Lake Michigan shore, and in about 1 year in 10 the north freezes by mid-September, so draining hose bibs and blowing out sprinkler lines by September 15 keeps an early freeze from bursting an outdoor line.

Furnace inspection before heating season

A pre-season furnace inspection prevents mid-winter heating failures and carbon monoxide risk.

Gutter cleaning after leaf fall

Clearing gutters after leaf drop prevents ice dams and roofline water damage in winter.

Around November · Verified before August 2026

Monitor roof snow load and ice dams through winter

Wisconsin averages about 10 to 15 inches of snow a month from December through February, far more in the northern snowbelt, and from Wausau north snow at least 5 inches deep covers the ground most days from late December into March, so roof snow and ice dams can push meltwater into ceilings and walls while heavy buildup strains the roof.
