Since 2005, we’ve been fighting for a better future for brokers.

We’ve been fighting for a better MLS solution for California real estate professionals for more than a decade. Now, it’s time to take action — once and for all.


The It’s My Business campaign is sponsored by California Regional MLS (CRMLS). With your help, we’re working to eliminate the political and historical hurdles that prevent MLSs in California from sharing data with each other.


It’s My Business is a grassroots effort for California real estate professionals to demand better data access.


Whether you’re a broker or an agent, you can help us get the statewide MLS data access we need and want, and break through the artificial barriers that get in the way of growing your business. We’re on your side.


Why a Statewide Data Access Initiative?

By 2005, virtually everyone was unhappy with the MLS landscape. It was both highly fragmented and inefficient. Brokers had to join and pay for multiple MLSs that ran incompatible systems with different sets of rules. This hobbled their ability to efficiently run their businesses in nearby and contiguous MLS areas.


That’s when the California Association of REALTORS® (C.A.R.) adopted its Six Guiding Principles for the MLS — and formally announced the statewide MLS initiative. The first result of the initiative was the formation of calREDD®, the state’s inaugural statewide MLS structure.


calREDD had a positive statewide impact. Many existing MLSs began to aggregate their data more aggressively, and vendors in the MLS technology space started to make their software platform-neutral. This led to greater consolidation, regionalization, and new levels of data sharing.


Statewide data access will be a win for brokers and agents everywhere in California.


In 2010, it became clear that merging calREDD with the Multi-Regional Multiple Listing Service (MRMLS) in Southern California would be the best way to carry on with the statewide data access initiative. When calREDD and MRMLS merged, the new entity became known as CRMLS.


It’s important to note that while CRMLS inherited the vision for a statewide MLS, CRMLS was created, and continues to operate, as a separate and independent entity from C.A.R.


CRMLS expanded its footprint many times this decade, and now serves more than 93,500 real estate professionals in California. It is the largest MLS in the United States.


CRMLS’s Objective

CRMLS’s objective is to facilitate data sharing between MLSs. Every broker and agent should be able to see all MLS listing data throughout the state – without having to join multiple associations and/or MLSs.


CRMLS also understands that brokers own their listing data, and MLSs should not make decisions about broker access to, or syndication of, data. The It’s My Business campaign focuses on data sharing between MLSs, not data syndication.


At the very least, we should share data.


CRMLS has developed technology internally to provide data shares with other MLSs throughout the state of California at a fraction of the cost of other data sharing techniques. In addition, CRMLS’s data sharing technology ensures a seamless technology experience for all that will view and use the shared data.

CRMLS’s development of these data sharing tools, and the It’s My Business campaign, aligns with the purpose of an MLS — to foster and facilitate cooperation and compensation.


You can help.

If you’re tired of the politics and the expense of belonging to multiple MLSs, raise your voice. If you’re tired of learning multiple systems just to do your job, join the campaign.


Tell your association that you want your MLS to share data, starting now. Let your MLS executive team and your volunteer leadership know that it’s no longer acceptable to operate as if the Internet didn’t exist — and consumers aren’t empowered.
