Wisconsin condominium reserve requirements

A plain-language summary of Wis. Stat. § 703.163. Last checked October 2026.

Who it applies to: Residential condominiums. Small condominiums are exempt unless they opt in, and an association may choose not to have a statutory reserve account with the written consent of a majority of the unit votes.
How often: If the condominium has a statutory reserve account, the annual budget must provide for reserve funds. The statute does not name a reserve study or set an interval for one.
Who can prepare it: The statute does not name a preparer. The association determines the reserve assessment.
What it must contain: In setting the amount, the association must consider the funds already in the account, the estimated cost of repairing or replacing common elements, and their estimated remaining useful life, among other factors.

Can a board do its own reserve study in Wisconsin?

Board may prepare it

Wisconsin asks the association to weigh current reserves, replacement costs and remaining useful lives when it sets reserve assessments. Those are the workbook's inputs, and no credentialed preparer is required.

Your governing documents may set stricter rules than the statute. Check them too.

The workbook

Reserve Study Kit is an Excel workbook that builds a 30-year reserve funding plan from your component list: every year's balance, percent funded, and the contribution that keeps you above your minimum.
