Buying or Selling a Home in Ontario, California: A Local Orientation

Where Ontario sits

Ontario is a city in the western part of San Bernardino County, in the region Southern Californians call the Inland Empire, roughly 35 miles east of downtown Los Angeles. The City of Ontario reports that it was incorporated on December 10, 1891, covers about 50 square miles and sits at roughly 925 feet of elevation. Ontario International Airport (ONT) lies within the city and is governed by the Ontario International Airport Authority, a joint powers authority of the City of Ontario and San Bernardino County. Metrolink commuter rail serves the area through the Ontario–East station, with Rancho Cucamonga station connecting to the airport by bus.

For a buyer that means a city with its own employment base, regional shopping and transport, next to Rancho Cucamonga, Upland, Montclair and Chino. For a seller it means a buyer pool drawn from across the Inland Empire and from people leaving Los Angeles and Orange counties for more space. The Ontario area page keeps the fuller, regularly reviewed orientation — layout, transit, what buyers and sellers should check — and links to the pages for Rancho Cucamonga, Chino and Fontana next door.

The three ZIP codes

Residential Ontario is covered by ZIP codes 91761 (the south and east, including the newer Ontario Ranch area), 91762 (the west) and 91764 (the north, toward the airport and the I-10). Housing stock ranges from early-twentieth-century homes near the historic core to mid-century tracts to new construction in the south. Rather than describe neighborhoods with claims we cannot source, we suggest using the property search, which shows current listings available through CRMLS for all three ZIP codes with photos, maps and details, no account required.

How property tax works here (and everywhere in California)

California property tax is set by Proposition 13. The general levy is 1 percent of the property’s assessed value, plus any voter-approved additional rates and direct assessments that apply to the parcel. A property’s assessed value is reset to market value when it changes ownership — so a buyer’s tax bill is based on what they pay, not what the previous owner paid — and thereafter can rise by no more than 2 percent a year under the inflation adjustment. Some newer developments also carry special assessments for community facilities; these appear on the tax bill and in the seller’s disclosures, and are worth asking about when you compare monthly costs between homes. Questions about your own tax situation belong with a tax professional or the San Bernardino County Assessor.

If you are buying in Ontario

The sequence is the same as anywhere in California: financing and pre-approval first, then the search, then an offer, inspection and appraisal, and closing. Locally, pay attention to the age of the home and its systems, HOA dues where they exist, special assessments in newer tracts, and the airport’s flight paths if noise matters to you. How buying works gives the overview, and requesting a showing on any home in the search is a request, not a commitment.

If you are selling in Ontario

Sellers here have the same three routes as anywhere: a prepared listing, an as-is listing, or a direct offer. Which fits depends on the home’s condition, your timeline and how much you want to be involved — here is how to compare them fairly. California disclosure duties apply to every route. Sapphire Realty’s office is at 3400 Inland Empire Blvd, Suite 101, Ontario, CA 91764, and a conversation about your home commits you to nothing.

About the numbers you will not find here

We deliberately do not publish median prices, days-on-market averages, school rankings or commute times on this page. Those figures change constantly and are often quoted without a source. When we cite a statistic anywhere on this site, we name where it came from and when. For current inventory and prices, the live search is the honest answer.
