Average Rent in Wisconsin: ZIP Rents & Heat-Included Budgets

What the rent evidence changes for a rental decision

Use Milwaukee’s tighter apartment evidence to investigate signed renewals rather than to remove all incentives automatically. For Madison and other Wisconsin rentals, identify who pays heat and how shared meters are allocated. Compare the complete tenant budget and the owner’s collectible premium separately.

Madison rental heating

A summer inspection cannot establish the winter operating budget

Madison’s Building Inspection guidance says 67°F must be maintained and that housing providers cannot choose a calendar date to turn heat on or off. Its repair guidance varies with outdoor conditions. This is municipal heating guidance, separate from the Dane County ZIP comparison.

A furnace that briefly runs during a showing does not establish peak-season reliability or cost. Transferring the utility payment to a tenant does not itself resolve a building’s condition or the owner’s applicable maintenance obligations.

Decision. Obtain a qualified heating-system inspection, service history and winter bills before the offer. Fund documented repair needs separately from the recurring heat allowance. Check the actual municipality rather than extending Madison’s guidance to every Dane County address.

What could change it. A documented efficient system and a complete service record can reduce uncertainty. A failing boiler, poorly controlled common system or unusually exposed unit can overturn a budget inferred from another apartment.

Records to obtain. Heating inspection, repair history and bids, complete winter bills, actual jurisdiction and lease utility responsibilities.

Compare rents across these county groups

These analyst-selected sets use the listed county labels and the same September 2026 observation month. Each ZIP receives one equal vote. They are not official metro definitions, exhaustive regions or bedroom comparisons.

32 distinct county labels appear in the current sample; geographic coverage is incomplete and uneven. Only currently available observations from the same latest month enter these comparisons. Older retained records and missing ZIPs do not enter as zero rents.

Keep the full-year heat bill inside the owner’s recurring budget

Hypothetical heat-included apartment: $1,525 monthly rent, 5% annual vacancy/noncollection, no free rent, $7,000 operating costs including $1,800 heat plus $5,200 other costs, $9,200 debt and $1,000 reserves. These are assumptions rather than Wisconsin survey expenses. Initial system replacement and acquisition cash require a separate budget.

Initial calculated result: $17,385 collected rent, $10,385 NOI before debt/reserves, and $185 cash after debt/reserves. Change the assumptions below to test your own budget.

Continue with the right geography and tool

• Wisconsin cap-rate research — Use a correctly allocated recurring income budget in a separate valuation analysis.
• Milwaukee County overview — Continue into the published county setting without assuming every building matches the apartment cohort.
• Dane County overview — Keep the Madison municipal rule and the broader county rent screen distinct.
• ZIP and bedroom HUD rent reference — a different measure from asking-rent ZORI; a PHA must still establish its payment standard and approve the actual contract.
• Property income calculator — use signed comparables and actual expenses for the subject property.

How these rent figures are calculated

State: Wisconsin · USPS WI · Census state FIPS 55. Zillow supplies postal ZIP observations with city and county labels. We filter to valid positive rents in this state and the latest common observation month, sort the values, and take the middle value, or the mean of the two middle values for an even count. Means are the sum divided by included ZIPs. No population, household or rental-unit weighting is added.

The all-home, all-bedroom ZIP series is smoothed, not seasonally adjusted. A bedroom rent cannot be inferred from it. Membership can change after a refresh, so a change in this page’s median is not a matched-sample rent-growth rate. This edition does not publish a ZIP-sample growth claim.

Data: Zillow Research · ZORI method · National ZIP source CSV. The state benchmark is our ZIP-based calculation, not a provider-published statewide estimate. Occupied-unit Census rent, listing medians, effective broker rents and HUD gross-rent references answer different questions and are not blended here.

The observation month identifies the rent data available for this comparison. Historical or missing latest observations stay out of the current sample. Check the date before comparing a property with a newly advertised offer.

Market and legal sources below were reviewed 2026-10-24. Their own periods are shown next to each claim. Broker samples and boundaries are not fully disclosed; surveys may share underlying providers and should not be treated as independent experiments. The market interpretation is conditional research, not a property-level income guarantee. Recheck local rules, signed comparable leases and actual expenses before using an illustration in a transaction.
