Yorkville Was the Fastest-Growing County in the U.S. in 2010. Two-Thirds of Its Homes Are Less Than 25 Years Old, and More Are Being Built Right Now.

Yorkville is a market shaped by a single decade. Kendall County, where Yorkville serves as the county seat, was the fastest-growing county in the United States around 2010 according to CNN's analysis of Census data. That growth wave produced hundreds of acres of planned subdivisions across Bristol, Kendall, and Fox townships, all built on former farmland, all with active HOAs, and all from an era of construction that buyers now evaluate alongside 2022 to 2025 new builds competing in the same price range. The practical challenge for appraisers: a 2006 colonial in Grande Reserve and a 2024 single-family in Caledonia may both be listed near $450,000, but they are not the same product from a buyer's perspective, and treating them as equivalent comps introduces error.

The price distribution in Yorkville reflects a market that has matured but not homogenized. The largest segment, 36.4% of homes, is in the $415,000 to $553,000 range. The next largest, at 30.7%, sits between $277,000 and $415,000. Active new construction at the city's north and west edges is pushing premium product into the $600,000 to $800,000 range. The 25.9% of homes built from 1970 to 1999 occupy the lower end of the market alongside townhomes from communities like Bristol Bay, which runs $220,000 to $380,000. Yorkville's 79.5% owner-occupancy rate, a median household income of $108,513, and 29.6% of the population under 18 point toward a family-formation market with strong underlying demand.

Yorkville also has appraisal factors that go beyond the typical fast-growth suburb. The BNSF rail line runs through the northern portion of the city, producing a noise and proximity discount for properties adjacent to the tracks. The Fox River creates both a premium for riverfront and downtown parcels and a flood zone complication for low-lying properties along the river corridor. Wrigley, a Mars Inc. manufacturing facility, is a significant local employer, adding an employment base that reduces the purely commuter-dependent nature of residential demand. Raging Waves Waterpark, at 45 acres the largest waterpark in Illinois, generates summer traffic on Yorkville's main corridors without meaningfully affecting residential values except for very proximate properties.

Yorkville's subdivision landscape is deep and well-documented. Grande Reserve is the city's largest planned community, with a mix of single-family and townhomes across multiple builder phases, an amenity center, and pricing from roughly $280,000 to $500,000 depending on vintage and size. Bristol Bay combines townhomes and detached homes in the $220,000 to $380,000 range and is the city's largest HOA community for attached product. Windett Ridge and Raintree Village represent established mid-range subdivisions on the north side, generally $350,000 to $550,000. Autumn Creek, which includes its own elementary school, and Heartland Circle sit in the $320,000 to $500,000 range. Caledonia is the newest high-end development, with recent construction from $400,000 to $650,000.

The downtown and Bridge Street area is Yorkville's oldest and most distinct neighborhood, with pre-1940 homes on both sides of the Fox River at Bridge Street. These properties are the hardest to comp in all of Yorkville: limited sales volume, strong lifestyle demand for walkability to the river and downtown commercial core, and no direct subdivision equivalents in the comp pool. Yorkville CUSD 115 serves the vast majority of the city with an A- Niche rating and is a consistent driver of buyer demand. The district operates Yorkville High School and the Freshman Academy. Properties near the Oswego border may fall under Oswego CUSD 308. Confirming attendance zone by parcel address is standard in every appraisal we complete near the city's eastern edge.
