HUD-VASH and Built for Zero: What’s Working — and How to Scale It

Homelessness among veterans is not unsolvable. Two complementary approaches — HUD-VASH vouchers that pair rental subsidies with intensive VA case management, and the community-driven, data-focused Built for Zero model — have driven measurable reductions in veteran homelessness. Below I summarize what the evidence shows, why these approaches work together, and clear, actionable steps to expand their success.

## What HUD‑VASH is — and why it works
HUD‑VASH (the HUD–VA Supportive Housing program) combines permanent housing vouchers from HUD with clinical case management and supportive services from the VA. That integration addresses both the primary barrier (affordable housing) and the underlying clinical and social needs that can lead to housing instability.

Evidence highlights:
– Multiple evaluations show HUD‑VASH significantly reduces returns to homelessness and decreases shelter and institutional stays compared with usual care (Urban Institute, VA studies). (See Urban Institute review of HUD‑VASH outcomes: https://www.urban.org)
– HUD‑VASH is targeted: vouchers are offered to veterans experiencing homelessness or at immediate risk, which concentrates resources where they prevent and end homelessness most efficiently (HUD program page: https://www.hud.gov/program_offices/comm_planning/hudvash).

Why this combination matters: rental assistance removes the immediate economic barrier to housing; intensive, coordinated case management addresses health, substance use, employment, and benefits access — preventing rapid returns to homelessness.

## Built for Zero: measurement, by‑name lists, and relentless problem solving
Built for Zero (run by Community Solutions) works with communities to reduce homelessness by using real‑time data, by‑name lists of people experiencing homelessness, and “rapid improvement” cycles to remove local process bottlenecks. The core idea: treat homelessness like a measurable problem to be solved, not an intractable condition to be managed.

Key outcomes:
– Dozens of communities using the Built for Zero model have achieved “functional zero” for veteran homelessness — meaning communities have systems low enough inflow that they can sustainably house veterans as they become homeless (Built for Zero/Community Solutions: https://community.solutions/built-for-zero).
– Communities using by‑name lists and active case conferencing shorten the time from identification to housing placement and improve match rates to programs like HUD‑VASH and Rapid Rehousing (NAEH descriptions and best practices: https://endhomelessness.org).

Why measurement works: a by‑name list makes each person visible to the system, enabling targeted outreach, faster referrals into HUD‑VASH slots or other housing resources, and the ability to monitor and iterate on process improvements in near‑real time.

## What the evidence says — concrete impacts
– Veteran homelessness has declined significantly over the last decade in the U.S., a reduction driven in part by outreach, targeted housing resources (including HUD‑VASH), and community strategies aligned with Built for Zero principles (see HUD and NAEH analyses: https://www.hud.gov and https://endhomelessness.org).
– Evaluations from independent researchers (including Urban Institute) demonstrate that permanent supportive housing and combined rental subsidy + supportive services models produce durable housing stability for vulnerable populations, including veterans.

These outcomes are not the result of a single tool but of coordinated tools: subsidies (to open housing slots), clinical supports (to stabilize), and data/process transformations (to direct scarce resources efficiently).

## What IS working — and what communities should replicate
1. Prioritize rapid matching of HUD‑VASH vouchers to veterans on by‑name lists. When communities maintain an accurate list and actively match people to HUD‑VASH as soon as vouchers become available, placement rates and retention improve.
2. Invest in landlord engagement and flexible move‑in assistance. Landlord outreach programs, damage mitigation funds, and short-term incentives reduce leasing barriers for voucher holders.
3. Pair vouchers with intensive, sustained case management. Short-term housing without supports risks turnover. VA case management tied to HUD vouchers reduces returns to homelessness.
4. Use real‑time data and daily/weekly case conferences. Built for Zero communities use regular “operational” meetings to remove bottlenecks (e.g., missing IDs, background check delays) that stall placements.
5. Make flexible funds available for non‑recurring expenses. Funding for furniture, transportation, and brief treatment needs prevents small but critical barriers from derailing housing.

## Actionable takeaways for policymakers and local leaders
– Expand and protect HUD‑VASH capacity. Increasing vouchers without the VA case management component reduces effectiveness; expansion should be matched with funding for supportive services (see HUD/VA program guidance: https://www.hud.gov/program_offices/comm_planning/hudvash).
– Scale by‑name lists statewide and train Continuums of Care in Built for Zero methods. Fund HMIS interoperability and staff time for active list maintenance and weekly case conferencing (NAEH and Built for Zero offer implementation guidance: https://endhomelessness.org; https://community.solutions).
– Invest in landlord incentives and rapid financial assistance. Small pots of flexible funds dramatically increase lease-up speed for voucher holders and reduce inventory loss.
– Measure outcomes that matter: inflow, average length of time homeless, and exits to permanent housing. Public dashboards and transparent targets keep stakeholders aligned.
– Prioritize equity and tailored strategies for veterans with compound needs (e.g., women veterans, veterans of color, those with serious behavioral health conditions). Disaggregated data uncovers disparities and targets resources where they will have the greatest impact.

## Final note: proven approaches + political will = scale
The combination of HUD‑VASH’s housing subsidies and VA supports with local, data-driven systems change (Built for Zero) has turned what was once an intractable problem for many communities into an achievable goal. Dozens of localities have shown that with the right resources — vouchers, sustained case management, landlord partnerships, and real‑time data systems — veteran homelessness can be ended at community scale.

If you work in local government, a VA medical center, a CoC, or a nonprofit partner: start by ensuring your by‑name list is accurate, prioritize HUD‑VASH referrals for the highest‑need veterans, and invest in landlord engagement and flexible move‑in funds. These are practical, evidence-backed steps that turn existing tools into durable housing outcomes.
