What Csi Support & Development Services does

Csi Support & Development Services is a resident-controlled non-profit cooperative housing organization headquartered in Warren, Michigan, providing affordable rental housing primarily to low-income seniors aged 62 and older across four U.S. states: Michigan (28 properties), California (16), Maryland (14), and Massachusetts (7). Since 1965, CSI has operated as a mission-driven provider of 65+ affordable housing communities under a cooperative governance model where resident members vote on operating decisions, participate in budget creation, and elect a 13-member Board of Directors; some properties (e.g., Mariposa Villa) extend eligibility to mobility-impaired disabled persons aged 18 and older. The core technology stack is the RENTCafe property management platform (Yardi Systems), which powers the website's property search, online applications, resident login portal, and electronic rent payment processing, supplemented by the Walk-in Payment System (WIPS) via PayNearMe for cash-paying members.

The revenue model combines rent paid by residents (capped at 30% of income) with federal and state housing subsidies covering the remainder, creating a stable, recurring revenue stream that is heavily dependent on government affordable housing programs (HUD, Section 8, LIHTC). CSI pursues development, acquisition, and renovation strategies — historically contributing 22 new co-ops totaling 1,455 units, 10 acquired properties totaling 1,180 units, and renovations of 1,807 units — alongside an affiliated CSI Housing Foundation that recycles property-sale proceeds into grants and favorable loans. The organization employs 251-500 people across four regional offices (Warren MI, Monrovia CA, Middle River MD, Malden MA) and is recognized by NAHMA through the Communities of Quality Corporate Partner designation and multiple Vanguard Awards, including the 2016 award for Wabash Estates.
