CES' project, the Los Angeles Center for Affordable Tenant Housing (LACATH), provides outreach, training and organizing assistance to tenants living in HUD subsidized housing where owners are seeking to opt-out of the project-based Section 8 rent subsidy contract or prepay the HUD subsidized mortgage, thus removing federal rent restrictions.

Assistance is also provided to subsidized housing tenants living at complexes subject to HUD's Mark-to-Market (M2M) program which reduces the subsidized rents where the HUD rent subsidy is above the area's market rents.

CES established a Countywide Alliance of HUD Tenants (CAHT), which is a federation of HUD tenant associations organized by CES. CAHT provides a forum for HUD tenants to support each other, develop strategies to preserve their affordable housing and contribute to national efforts to defend the rights and homes of low income HUD subsidized tenants.

CES is an affiliate of the National Alliance of HUD Tenants (NAHT), the leading voice of HUD tenants on federal legislative and regulatory issues.
