The Most Expensive Zip Codes in Connecticut – Gold Coast Continues to Dominate

Quick facts:

  • Greenwich’s 06830 is the #1 most expensive zip code in Connecticut
  • 7 Connecticut zips feature medians above the $1 million mark
  • Fairfield’s 06824 saw the highest sales activity with 540 transactions
  • South Kent prices grew by a whopping 48%

Connecticut’s real estate market continued to perform modestly throughout 2017, although real estate indicators showed markedly more positive signs than during the year before. While 2016 saw prices dip, 2017 brought modest price gains, with December figures up 1% for single-family homes and 0.9% for condominiums, per the Connecticut Association of Realtors (CTR).

When it comes to Connecticut’s 50 most expensive zip codes, however, The Constitution State saw medians grow in 25 zips, while 5 zip codes maintained year-ago figures. Furthermore, 10 new zips made it into our top 50, and only one zip code – 06777 in New Preston Marble Dale – experienced double-digit price reductions. On the other end of the spectrum, 8 zip codes saw their medians grow by double-digit percentages.

Among them was Greenwich’s 06830, which saw its median sale price expand by 16%. Reaching a median of $1,597,500, this pricey zip rose from last year’s #2 to become the #1 most expensive zip code in Connecticut. In fact, 06830 is among the 100 most expensive zip codes nationwide, ranking 89th.

Greenwich was also the setting for Connecticut’s largest sale in 2017. Trading hands in late November, 9 Sabine Farm Road, Greenwich fetched $25,000,000 in zip 06831, the #8 most expensive in the state. The 19.5-acre farm was initially listed for $31.5 million by hedge fund billionaire Stanley Druckenmiller, after picking up the property for a reported $23 million back in 2004, per  Greenwich Time.

Built in 1910, the decadent estate was designed by famed architects Hunt & Hunt for publishing tycoon H. J. Fisher. The 12,200-square-foot mansion underwent significant upgrades and renovations during Druckenmiller’s ownership. The estate includes an 8-bed main house, a 3-bed guest cottage, pool, cabana, 4-car garage, a bevy of fireplaces, and meticulously landscaped grounds.

While Greenwich’s 06831 may have boasted the year’s priciest sale, the largest sales volume was registered in Fairfield’s 06824. Connecticut’s #14 most expensive zip closed 540 sales in 2017 with a $625,000 median sale price. Stamford’s 06902 was close behind with 513 sales, although at a noticeably lower median of $368,500.

With a median sale price of $1,575,000, Riverside’s 06878 ranks as the #2 most expensive zip in Connecticut, thanks to a whopping 37% price expansion. Ending the year as Connecticut’s #10 priciest zip, Southport’s 06890 also saw a major gain in its median sale price, expanding by 23%. At a jaw-dropping 48% appreciation in median sale price, South Kent’s 06785 emerged as the #1 fastest rising zip code in Connecticut in 2017.

Due to a modest 2% median price growth, 06870 in Old Greenwich slid from 2016’s #1 spot to become the #3 most expensive zip code in Connecticut with a median of $1,450,000 and 91 sales. Comparatively, 06870 ranked as the #77th priciest zip code in the U.S. in 2016.
