The Commercial Alliance Community

The Commercial Alliance is a community created to bring together commercial real estate practitioners from across the Chicagoland area. Through seminars, networking events, education, and advocacy, we unite REALTOR® and non-REALTOR® commercial practitioners, and others in the industry to help our members effectively compete in the marketplace.

Our goal is to advance the interests of our members through legislative influence, professional development, resources, and opportunities.

Existing members of the Alliance can access commercial forms and keep up-to-date with commercial-related news and events by joining our Commercial Facebook page.
