Using Zillow Home Value Index numbers from March 2026, researchers ranked the most expensive ZIP codes in the state based on typical home value. The results paint a very clear picture—if you want to live in some of Connecticut’s most desirable commuter towns near New York City, it’s going to cost you.

Greenwich didn’t just appear on the list, it practically took it over, claiming multiple spots in the Top 10, including the top three positions. Every single ZIP code in the ranking came from Fairfield County, showing just how concentrated high-end real estate is in that part of the state.

Here is the Top 10 Most Expensive ZIP Codes in Connecticut:

1. 06878 – Greenwich – $2,515,258
2. 06870 – Greenwich – $2,502,548
3. 06830 – Greenwich – $2,326,491
4. 06820 – Darien – $2,259,614
5. 06853 – Norwalk – $2,091,582
6. 06840 – New Canaan – $2,045,176

That means even the “cheapest” ZIP code in the Top 10 still has a typical home value of more than $1.4 million. That’s not entry-level housing—that’s elite airspace.

Experts say demand remains high in these towns because of their access to New York City, strong schools, coastal charm, and overall lifestyle. Translation: people are paying top dollar for convenience and prestige.

For everyone else in Connecticut, this list is also a reminder that there are more affordable options if you head farther from the Gold Coast.

But if your dream is Greenwich, you may need a trust fund, a hedge fund, or to invent something life-changing before the weekend.

It’s still kind of wild to step back and look at numbers like this and realize just how much wealth is packed into a relatively small corner of Connecticut. You don’t really feel it day to day until you see it laid out in rankings like this, where entire ZIP codes are sitting at multi-million-dollar averages like it’s completely normal.

It annoys me to know that I'm smarter than 80% of the people that hold that wealth.
