McCormack Baron Salazar is an American real estate development firm based in St. Louis, Missouri specializing in economically integrated urban neighborhoods[1] with more than $4.23 billion invested in affordable and mixed-income housing projects.

Baron was representing tenants in a public housing rent strike and McCormack was working with the local Teamsters as part of a coalition called in to help resolve the conflict.

In contrast to large-scale urban renewal projects, early McCormack Baron developments focused on small, single site, mixed income rental properties with access to schools, services and local economic opportunities for residents.

Sunwheel installs solar panels on public, affordable and mixed income housing developments to help lower energy costs.

[10] The firm uses the federal New Markets Tax Credit Program to bring renewable energy components to affordable housing communities in St. Louis, New Orleans, Memphis and various cities in California.
