Diamond Bar sits where the 57 and 60 freeways meet on the eastern edge of Los Angeles County, a hillside city of ridgelines, canyons, and cul-de-sac streets. Inventory runs from 1970s and 1980s tract homes through custom builds inside the gated Country Estates, and the city is divided between two school districts along Grand Avenue.

Frequently Asked Questions

Which school district serves Diamond Bar?
Two of them. Walnut Valley Unified serves most of the city south of Grand Avenue, and Pomona Unified serves the area north of it. Grand Avenue is only a rough dividing line, so confirm the assigned schools for a specific address rather than relying on the city name.
What ZIP codes cover Diamond Bar?
91765 and 91789. Both are shared with neighboring cities — 91765 also reaches Pomona and Rowland Heights, and 91789 also reaches Walnut, Rowland Heights, City of Industry, La Puente, and Pomona. A ZIP code alone does not establish that a home is in Diamond Bar.
What kind of homes are in Diamond Bar?
Predominantly detached single-family homes on hillside lots, with a concentration of 1970s and 1980s tract construction and larger custom properties in The Country Estates, a gated community in the southern hills. Townhomes and condominiums exist but make up a smaller share of the market.
