The Ordinance Every Winnetka Teardown Now Has To Build Around

In 2023, Vijay and Shiraz Kotte paid $12.3 million for a century-old Spanish Revival mansion on Sheridan Road, the kind of property most buyers would restore rather than raze. A year later, the Village of Winnetka passed a construction rule that the Kottes believed would cost them millions in value. So they joined a lawsuit against it.

By August 2025, the mansion was gone. By December 2025, the Kottes had dropped their lawsuit. And today, on the same lakefront lot, they are building one of the largest lakefront homes in Winnetka, roughly 28,690 square feet, at an estimated construction cost of $10 million, fully compliant with the very ordinance they once fought to overturn.

That reversal is not really a story about one family changing its mind. It is a story about what happens when a rule written to stop a single project becomes the rulebook for everyone who comes after it, including the people who hated it most.

A Rule Built For One House, Now Applied To All of Them

The ordinance traces back to a much larger fight. In 2024, Winnetka moved to limit construction on and near the bluffs along Lake Michigan, a response widely understood as targeting billionaire Justin Ishbia's proposed $77 million megamansion on Sheridan Road. The village could not write a rule for one address, so it wrote one for the bluff itself. Anyone building or rebuilding along that stretch of lakefront now answers to it, regardless of what they intended to build or when they bought the land.

That is the part sellers and buyers along Winnetka's lakefront tend to underestimate. A rule aimed at stopping an outlier does not stay contained to the outlier. It becomes the baseline. Vijay Kotte, CEO of Chicago-based GoHealth, told village officials at the 2024 meeting where the ordinance passed that he would have reconsidered both the purchase and the price he paid had he known the restriction was coming. The Kottes bought before the rule existed and are building after it took effect, on a lot they already owned. The next buyer of bluff-adjacent land in Winnetka does not get that sequencing. They inherit the rule from day one, priced in or not.

What Building Under It Actually Looks Like

The Kotte project is the clearest live example of what compliance costs in practice. The permit application shows the couple received approval to build in June 2025, and reporting on that application found little conflict between the design and the ordinance's terms once the plans were submitted. The new house does not simply replace the Clement Stone Mansion, a landmark built in 1912 that had passed through owners including hotel magnate Albert Pick and Wander Company president James G. McMillan before self-help author W. Stone Clement lived there until his death in 2005. It replaces it under a different set of rules than existed when the mansion was standing.

For anyone else weighing a teardown on or near the bluff, that is the practical takeaway: the design phase now includes a bluff-compliance review that did not exist for the home currently on the lot. Setbacks, shoreline structures, and grading all get checked against the 2024 rule before a demolition permit is even considered, not after.

The Closing Quirk Nobody Warns You About

The bluff ordinance is the headline-grabbing piece of Winnetka's teardown market, but it is not the only mechanic that catches people off guard at the closing table. Winnetka operates its own municipal electric utility, an arrangement most Illinois villages do not have. That means a Winnetka closing cannot complete until the seller's final village electric and water charges are settled directly with the village, a step that simply does not exist in most Illinois residential closings and routinely surprises out-of-market buyers, sellers, and even attorneys who have not closed a Winnetka deal before.

For a teardown specifically, the list gets longer. Before a demolition permit clears, the closing team typically confirms the property is not landmarked or sitting inside a historic district that would block demolition outright. Winnetka has real stakes here: the village is home to the landmark Crow Island School and houses designed by George Maher, Walter Burley Griffin, Howard Van Doren Shaw, and David Adler. A survey gets reviewed for easements that could conflict with the new footprint. And the gas line, run by Nicor, needs coordinated municipal shutoff rather than a simple disconnect, since a teardown is treated as a development project rather than a routine sale.

None of these steps are unusual on their own. What makes Winnetka different is how many of them stack on a single transaction, and how few closings anywhere else in the region combine a municipal utility payoff with bluff-compliance review and historic-district screening in the same file.

What the Numbers Are Actually Telling You

The headline price data on Winnetka can be read as a straightforward story of appreciation. As of the update posted May 31, 2026, the average home value in the village stood at $1,876,083, up 11.8% over the prior year. Read alone, that looks like ordinary North Shore demand.

Look at what actually changed hands and the picture sharpens. The median sale price in Winnetka reached $2,247,500 in May 2026, well above that broader average value figure. A median sitting that far above the village-wide average value is what you would expect in a market where the transactions actually closing skew toward the high end, the kind of sale where a buyer is underwriting a construction project on the land rather than simply purchasing the structure sitting on it.

That distinction matters for how a seller should think about pricing an older home in Winnetka right now, particularly on or near the bluff. The conversation is less about what the existing structure is worth and more about what the lot can support once the ordinance, the demolition permit process, and the closing mechanics are all accounted for. A buyer's team is already pricing that complexity in. A seller's asking price should reflect the same read of the market, not a comparison to a home sale that closed before any of these rules existed.

A Few Questions Worth Settling Early

Does the bluff ordinance only affect homes directly on Lake Michigan? It targets construction on and near the bluffs specifically, which means the properties most affected sit along the lakefront corridor rather than the village broadly. Anyone considering a rebuild in that zone should have the parcel checked against the ordinance before finalizing design plans, not after.

Is the electric utility payoff only a teardown issue? No. Because Winnetka runs its own electric utility, the final payoff applies to any residential sale in the village, not just projects involving demolition. It is simply more visible in a teardown closing because it appears alongside several other village-specific steps at once.

Is a demolition permit the same as a building permit here? They are handled as separate steps, and the demolition permit typically requires confirming the property is not landmarked or inside a historic district before it will clear, which is why that check happens early in a teardown transaction rather than as a formality at the end.

If you are weighing whether a Winnetka property still makes sense as a home to keep, a home to sell as-is, or a lot to rebuild under the current rules, that is exactly the kind of conversation worth having before you list or make an offer, not after.
