The Case Manager's Field Guide to Maricopa County Resources

By Common Ladder · Updated May 20, 2026 · 10 min read

This guide is written for social workers, case managers, and outreach workers who navigate Maricopa County's homelessness service ecosystem daily. It covers the key programs, how coordinated entry works, and the fastest paths to stable housing for different client profiles.

The Coordinated Entry System (CES)

Maricopa County operates a Coordinated Entry System (CES) that standardizes how people experiencing homelessness are assessed and matched to appropriate housing and services. Understanding CES is foundational to navigating the system effectively.

How clients enter CES

Access points are distributed across the county. Clients can enter through:

Assessment tools

The primary assessment tool used in Maricopa County is the VI-SPDAT (Vulnerability Index — Service Prioritization Decision Assistance Tool), though the system has been transitioning toward newer assessment approaches. Scores help determine prioritization for housing interventions.

Housing intervention types

Understanding which intervention is appropriate for which client profile saves time and improves outcomes.

Emergency shelter

Short-term, low-barrier accommodation. Appropriate for clients who need immediate safety. Not a solution — a first step. Key providers: CASS (adults and families), UMOM (families and youth), Sojourner Center (domestic violence survivors).

Rapid Rehousing (RRH)

Short-term rental assistance plus case management to move clients from homelessness into permanent housing quickly. Best for clients who can sustain housing independently with modest support. The assumption is that the primary barrier is financial, not a need for intensive ongoing services. Typical duration: 3–24 months of rental assistance.

Permanent Supportive Housing (PSH)

Long-term or permanent housing with on-site or linked supportive services. Appropriate for clients with chronic homelessness and/or high service needs — significant mental illness, substance use disorder, physical disability. PSH does not require sobriety or treatment compliance as a condition of tenancy.

Transitional Housing

Time-limited housing (typically up to 24 months) with structured programming. Increasingly less common as the field has moved toward Housing First models, but still valuable for specific populations — particularly youth and people leaving correctional settings who benefit from structured environments.

Key providers by population

Single adults

Families

Youth (under 25)

Veterans

Domestic violence survivors

Benefits navigation essentials

Getting clients connected to benefits is often the difference between housing stability and return to homelessness. Key programs:

ID recovery

Missing ID is one of the most common barriers to housing and benefits. The process in Arizona:

Several Phoenix nonprofits have ID Clinics that handle the full process in one visit — check with CASS, Lodestar, and St. Vincent de Paul for current clinic schedules.

The fastest path to housing stability is almost always: get ID, get benefits, get into rapid rehousing, then work toward long-term stability. The sequence matters.
