A Tale of Two Zip Codes

Chantilly is unique in Northern Virginia because it straddles the border of the two most powerful counties in the state. For homebuyers, understanding the difference between 20151 and 20152 is the most critical step in the search process.

20151 (Fairfax County Side): This is the "classic" Chantilly. It features established neighborhoods with mature trees, no HOAs (or low fees), and diverse housing styles from the 1980s and 90s. It sits closer to Route 28 and I-66.

20152 (Loudoun County Side): This is the "new" Chantilly (often called South Riding). It is defined by massive master-planned communities with resort amenities, newer construction (2000+), and a slightly more suburban/planned feel.

Jamil Brothers Insight

The Value Difference

"We often see buyers start in 20152 because they want the shiny new construction of South Riding. However, savvy buyers often pivot to 20151 neighborhoods like **Chantilly Highlands** or **Brookfield** because you get a larger lot and lower HOA fees, while still being just 5 minutes from the same amenities."
