Bayside homeowners have a June 24 Board of Review deadline to challenge assessments

Bayside property owners who think their 2026 assessment is wrong have a narrow window to act: the village’s Board of Review is set to adjourn to Wednesday, June 24, 2026, at 4:00 p.m. in the Village Board Room at 9075 North Regent Road. The village notice says Open Book was held May 20 from noon to 4:00 p.m., which is the earlier chance to talk informally with the assessor.

That timing matters because Open Book and the Board of Review are not the same step. The Wisconsin Department of Revenue says Open Book is when the assessment roll is open for examination and owners can discuss value with the assessor. The Board of Review is the formal hearing stage, where a property owner who still disputes the assessment must present evidence and ask for a change.

What to bring to the hearing

The state’s 2026 Guide for Property Owners says residents should be ready to explain the value they believe is correct and the information they used to reach that number. Practical documentation can include recent comparable sales, an appraisal, repair estimates, photos of condition problems, and prior records that help support the owner’s case.

Witnesses or experts can also help, but the guide says they should be prepared to document their testimony. The assessor will have a chance to present evidence too, so the hearing is meant to be a documented review, not a casual complaint session.

Residents now have a fresh state reference point to check before the hearing. On June 2, 2026, the Wisconsin Department of Revenue posted its updated Annual Assessment Summary Report, which includes general information, total taxable property value, real estate sales, and assessment levels and types for municipalities.

That summary can help Bayside owners compare their property with the broader assessment picture, but it is not a ruling on any individual home. It also does not mean every homeowner should appeal or that taxes will automatically change.

If you miss the hearing

If a resident still wants to appeal after the Board of Review, the DOR guide says the next step can be a certiorari appeal to circuit court within 90 days after receiving the board’s notice. That review is limited to the BOR record, which is why the local hearing window matters so much.

For Bayside homeowners, the practical next step is simple: check the notice, gather documents now, compare your assessment with recent sales and state summary data, and be ready for June 24 if you plan to object. In this process, a paper trail matters more than a last-minute argument.
