The new year is going to bring excitement, hope, and change.

In this spirit, we are pleased to announce the launch of the NorCal MLS Alliance on January 20, 2021.


The NorCal MLS Alliance is a coalition of the seven leading Northern California MLS’s whose goal is simple: provide you with access to the most listing data possible all in one place.

This means that the data available to you from our NorCal MLS Alliance partners will now be accessible in its entirety on our home platforms. You will no longer need to sign in to another MLS to view their data, it will all be available on Paragon and ConnectMLS.


The NorCal MLS Alliance is made up of bridgeMLS, BAREIS, Bay East, CCAR, SFAR, MetroList, and MLSListings.

Because of this powerful new alliance there will be some changes. Single Sign-On to other MLSs will be deactivated starting on January 20, 2021, as there will no longer be a need for it.

In light of this, below are some things you’ll need to do:

Load all listings in Paragon

If you have any active or pending listings on other MLSs, you will need to input them on your bridgeMLS Paragon before or after January 20.

All SSO Datashare Listings will be cancelled

On January 20 any listings you have on datashare MLSs will be cancelled and Paragon listings will be picked up and displayed in their place.


You’ll want to export any contact or client information you want to keep that is hosted on the datashare MLSs and import them into paragon or ConnectMLS.

Recreate Saved Searches and Auto notifications

After the launch, you’ll want to recreate any saved searches or automatic notifications that you’ve set up for clients on any datashare MLSs and put them on Paragon or ConnectMLS
