Because a ZIP code is a mail delivery route and a city is a government, and on the Palos Verdes Peninsula the two were drawn at different times for different jobs. 90274 covers homes in Palos Verdes Estates, Rolling Hills Estates and Rolling Hills. The Postal Service’s own place name for 90274 is Palos Verdes Peninsula, and that is not a city: no city hall, building rules or tax rate go with it.
The cities came first. Palos Verdes Estates incorporated on December 20, 1939, Rolling Hills on January 24, 1957 and Rolling Hills Estates on September 18, 1957. ZIP codes arrived nationwide on July 1, 1963, and they were laid out to fit mail delivery, not city limits. Nothing required the two maps to agree, and here they don’t.
For an owner it is a mailing detail. For a buyer it decides who reviews the remodel, which rules govern the lot and which tax rate lands on the bill.
Does 90275 work the same way?
Yes, from the other side. Most Rancho Palos Verdes addresses use 90275, and that city incorporated in 1973, ten years after ZIP codes arrived. The Postal Service’s preferred place name for 90275 is Rancho Palos Verdes, but it also accepts Rolling Hills Estates, Palos Verdes Estates and Palos Verdes Peninsula on 90275 mail. A listing that reads Rolling Hills Estates, CA 90275 can sit inside Rancho Palos Verdes, so the city name on an address proves no more than the ZIP code does.
Where does “Palos Verdes Peninsula” show up instead of a city?
Most often on listings. On October 10, 2026, several active listings on our Monte Malaga page gave their address as Palos Verdes Peninsula, CA 90274. Monte Malaga is a neighborhood of Palos Verdes Estates, so those homes are in Palos Verdes Estates and under its rules. A buyer comparing a listing marked Palos Verdes Estates with one marked Palos Verdes Peninsula may be looking at houses on the same street.
What changes from one city to the next?
In Palos Verdes Estates, the Palos Verdes Art Jury reviews any change to a home’s exterior, and its approval is required before work begins. The Art Jury is administered by the Palos Verdes Homes Association under recorded deed restrictions.
Rolling Hills is a 1,920-acre city behind staffed gates at Main, Crest and Eastfield, which control all vehicle access around the clock.
In Rolling Hills Estates, value is carried by the lot, the view, the equestrian overlay and the distance to Peninsula Center, and building is reviewed under the City’s own codes.
Property tax follows the city too. Each city’s parcels sit in their own tax rate areas, so two 90274 homes bought at the same price can carry different annual bills.

How do you confirm the city for an address?
Look up the parcel on the Los Angeles County Assessor’s portal. The record lists the parcel’s tax rate area, and a tax rate area sits inside a single city. Then confirm with that city’s planning department before relying on any rule that depends on it.
Check every time near a city line. On our La Cresta, Silver Spur and Country Club pages, the line between Rolling Hills Estates and Rancho Palos Verdes crosses the neighborhood.
