Old Arcadia:
The Earliest Platted. The Largest Lots.
The Deepest Pedigree.

Phoenix, Arizona · 85018 · The Western Core

Old Arcadia is the western, earliest platted portion of the original 1919 Arcadia subdivision. It contains the largest lots and the deepest historical pedigree in the entire Arcadia area, including some of Phoenix’s most architecturally significant midcentury residences designed by prominent Arizona architects of the postwar era. This is where the Arcadia story began, and it is where the most historically important homes in the neighborhood still stand.

“Old Arcadia is where Arcadia began. The 1919 plats, the largest lots, and some of the most important midcentury residences in all of Phoenix. For buyers who value architectural history and provenance, there is no substitute.”
— Anne Sostman | The Scottsdale Agent

Overview

What Is Old
Arcadia?

Old Arcadia is the western, earliest platted portion of the original 1919 Arcadia subdivision, the area where the Jordan, Grace and Phelps Land Company first created what they called the only large scale upper class rural estate development in the central Salt River Valley.

The lots here are the largest in the entire Arcadia area, often exceeding one acre. Many contain original midcentury residences designed by prominent Arizona architects of the postwar era, including homes that are recognized as significant examples of midcentury modern, Pueblo Revival, and early contemporary desert architecture.

Old Arcadia attracts buyers who value architectural history, provenance, and the prestige of owning a landmark property. The combination of lot size, historical significance, and irreplaceable positioning at the foot of Camelback Mountain creates a market where properties are rarely available and command premium pricing when they do appear.
