Boulder has no shortage of desirable neighborhoods, breathtaking views, and homes that seem to blend seamlessly with the foothills. But when it comes to the single most expensive and wealthiest ZIP code in town, one area consistently rises to the top: 80304.
Covering a wide stretch of North Boulder—from the tree-lined streets of Mapleton Hill to the quiet ridgelines above Wonderland Lake—80304 has become one of Colorado’s most sought-after destinations. With soaring home values, limited inventory, and some of the city’s most iconic outdoor access points, it’s a ZIP code that tells the story of modern Boulder: natural beauty, strong community, and a premium way of living.
Why 80304 Is Boulder’s Wealthiest ZIP Code
According to recent home-value data from sources like the U.S. Census Bureau and the Colorado Association of Realtors, 80304 has consistently ranked at or near the top of Boulder’s real estate market in both median sale price and median household income. Limited housing stock mixed with extraordinary demand has pushed prices into territory usually associated with elite ski towns and tech-driven hotspots. Many properties here routinely exceed two to five million dollars, and renovated or custom-built homes can climb far higher.
But the explanation isn’t just the numbers. People pay a premium here because the area offers something rare—even for Boulder.
