10 Most Expensive ZIP Codes in Connecticut

Here’s a report card you should be paying attention to. And you may want to think twice about living in a place that was graded with a D. Niche has come out with its new 2019 rankings of the “Best Places to Live” in Connecticut, but for at least the third year in row, it took a bit of a unique approach: The consumer rankings service assigned a grade, on an A+-to-D scale, to almost every town in the state.

The most expensive ZIP codes in the country are in California and New York, according to America’s most expensive ZIP codes rankings by PropertyShark. To find the priciest enclaves, PropertyShark analyzed all real estate transactions—condominiums, single- and two-family homes, as well as coops—that were completed in 2018, excluding package deals.

Not surprisingly, New York City and San Francisco were the two cities with the most ZIP codes in the ranking. Just across the Long Island Sound, Connecticut had its share of pricey neighborhoods, with four ZIP codes making the top 100 list—the most expensive being Riverside (06878). The city snagged the 49th spot. Connecticut’s Old Greenwich (06870), Greenwich (06830), and Cos Cob (06807) also made the site’s top 100.


  • Four Connecticut cities ranked among the top 100 list of most expensive ZIP codes in the country.
  • Riverside was the highest in the 49th spot with a median home price of $1.855 million.
  • Old Greenwich, Greenwich’s 06830, and Cos Cob also made the top 100.
  • Other most expensive ZIP codes in Connecticut are Darien, New Canaan, and Norwalk.
  • Westport, Greenwich’s 06831, and Southport rounded out the top 10 most expensive ZIP codes in Connecticut.

What $1.855 Million Buys You in Riverside

The median home price in Greenwich is $1.855 million, which could be considered a relative bargain for the area. At that price, buyers can expect homes of about 4,000 square feet, with four bedrooms and six baths, fireplaces, gourmet kitchens, French doors, pools and plenty of outdoor space with great landscaping—all on about one acre of land.

The most expensive home on the market in Riverside is a 0.88-acre home priced at $3.595 million, complete with five bedrooms and six baths, and almost 5,300 square feet of living space.

The Bottom Line

Connecticut’s most expensive ZIP codes are all part of Fairfield County on the Gold Coast, and are an easy commute to the New York City area. Many people who work in New York City live in Connecticut, where they’ll get a lot more house for their money. For $1.855 million in Riverside, you can get into a home that is a few thousand square feet with several bedrooms on a couple of acres. At that price in Manhattan, you’ll probably be looking at a modest two-bedroom condo—if that. And Connecticut offers plenty of green space to enjoy the outdoors and get away from the city.SPONSORED
