New Castle

New Castle spans zip code 19720 — one of the largest single zip codes in the state, covering everything from the historic waterfront district near the Delaware River to newer residential developments further inland.

Because 19720 covers so much ground, “New Castle” can mean very different things depending on the specific neighborhood — from the cobblestone streets and colonial-era homes of Historic New Castle, to established mid-century neighborhoods, to newer construction communities. We help buyers understand which part of 19720 actually fits what they’re looking for, since price, style, and lot size vary significantly across the zip code.

New Castle offers some of the most historically distinctive housing stock in the state, along with strong value relative to comparable homes in Newark or North Wilmington, plus easy access to Route 13, I-295, and I-95.

Living here means having Historic New Castle’s dining scene right outside your door — Jessop’s Tavern serves Colonial-inspired fare and one of the largest Belgian beer selections in the area inside an actual 18th-century building, while newer spots like Zollie’s Jazz Cucina add fresh energy to the same cobblestone streets.
