IDX in Ontario
MLS listings on your website, for Ontario agents and brokers.
Ontario listings live in California Regional MLS (CRMLS), the MLS covering San Bernardino County. A Ontario agent or broker gets them on a website with two things: a CRMLS-licensed IDX vendor and an IDX Request Form signed by the broker of record. HomesIDX is that vendor: the full CRMLS feed as a JSON API, a one-line embed, or a hosted search page, refreshed about every 15 minutes, with attribution and display rules handled, from $49 a month.
The Ontario market, from a website's point of view
Ontario Ranch is among Southern California's largest new-home builds, layered on an established airport-adjacent city. New-community buyers research heavily online before ever visiting a model home.

Common questions
Is Ontario covered by CRMLS?
Yes. Ontario is in San Bernardino County, which sits inside California Regional MLS (CRMLS) coverage, so Ontario listings are entered in CRMLS and available to IDX displays run by CRMLS participants and subscribers.
How do I get Ontario MLS listings on my website?
Through a CRMLS-licensed IDX vendor plus a CRMLS IDX Request Form signed by you and your broker of record. Once CRMLS confirms, the vendor serves Ontario listings to your site as an API, an embed, or a hosted search page.
How current are Ontario listings in the feed?
HomesIDX replicates the CRMLS feed incrementally about every 15 minutes with a daily reconciliation pass, well inside the 12-hour refresh MLS rules require, so new Ontario listings and status changes show up in minutes.
