It costs more to jail someone than to house them.
Supportive housing keeps people housed and, for the expensive high-need cases, costs less than the jail-and-ER status quo it replaces. The evidence is randomized, not anecdotal.
This page grades the housing evidence and the cost comparison separately, and keeps the limits in view: the savings are strongest for the highest-need people, not everyone, and the famous “we ended homelessness” headlines are oversold.
What this page is about
Housing First puts people into stable housing without preconditions, then adds voluntary support. Across the largest randomized trials it keeps people housed far better than the treatment-first status quo. For the highest-cost cases, people cycling through jail, the ER, and detox, it costs less than leaving them on the street.
The honest version has limits, and we keep them. The cost savings are strongest for high-need people, not everyone; some famous figures like Utah's “91% drop” are oversold; and for the most disabled, housing is ongoing support, not a path to a paycheck.

It costs more to jail someone than to house them.
Supportive housing keeps people housed and, for the expensive high-need cases, costs less than the jail-and-ER status quo it replaces. The evidence is randomized, not anecdotal.
A prison cell costs more than a housing unit
The Vera Institute put the average cost to hold one person in state prison at $33,274 a year, ranging from $14,780 in Alabama to $69,355 in New York. City jails run higher still. Supportive housing, by contrast, generally costs about $10,000 to $25,000 a year per person.
| Cost per person, per year | Amount |
|---|---|
| Incarceration, state prison (Vera, average) | $33,274 (range $14,780–$69,355) |
| Supportive housing (typical range) | ~$10,000–$25,000 |
| Big-city jail (e.g., New York City) | Several hundred thousand per person |
The rural sharpener makes it worse for the prison side. Prisons are built on the cheapest rural land, in the lowest-cost counties, so that $33,274 average is measured in the most favorable possible setting, and it still runs above the cost of housing someone in a city.

The record, claim by claim
Housing First keeps people housed, and the proof is randomized trials, not anecdote.
FACTAt Home/Chez Soi, a $110 million randomized controlled trial run by the Mental Health Commission of Canada across five cities with more than 2,000 participants, found that Housing First rapidly and durably housed people with serious mental illness compared with treatment as usual. The 2018 National Academies consensus report reached the same conclusion: the evidence that permanent supportive housing improves housing stability is strong.
For high-need people, supportive housing cuts jail stays, police contacts, and emergency care.
FACTThe Denver Supportive Housing Social Impact Bond, a five-year randomized controlled trial of 361 chronically homeless people with frequent criminal-justice and emergency contact, found that those referred to supportive housing had large gains in housing stability and roughly 34 to 40 percent fewer jail stays and police contacts, along with reduced detox and emergency use. It is the direct test of housing versus jail, at randomized-trial strength.
It costs less per person to house someone than to jail them.
FACTThe Vera Institute put the average cost of a year in state prison at $33,274, from $14,780 in Alabama to $69,355 in New York, with city jails higher still. Supportive housing typically costs $10,000 to $25,000 a year. Even at the high end of housing, the number sits below the prison average, and far below a big-city jail. One caveat, from Vera itself: cutting the prison population by one person does not save the full average, because much of the cost is fixed, which is why the randomized Denver result, measuring actual reduced service use, carries the point.
Prison is a compounding cost: most people released are rearrested, partly because a record bars them from jobs and housing.
FACTThe Bureau of Justice Statistics found that about 68 percent of released state prisoners were rearrested within three years and about 77 percent within five. The recidivism research documents part of the reason: prison erases work history, and a criminal record locks people out of jobs and apartments, so the system helps generate the reoffending it then pays again to incarcerate. A prison sentence is a multi-year cost that tends to refill itself; housing assistance is usually time-limited and can end.
The honest limit: the savings are strongest for high-need cases, and for the most disabled the win is stability, not a paycheck.
FACTThe 2018 National Academies review is explicit that the evidence for cost offsets is strongest for high-need, high-utilizer people, and thinner at the population level. And the 'becomes a taxpayer' outcome applies mainly to the non-chronic majority, people one crisis from the street who can re-enter work once housed. For the most disabled, permanent supportive housing is ongoing, and the real win is avoided jail and emergency costs plus stability, not employment. We hold that line so the case cannot be dismissed as overselling.
Where the evidence is strong, and where it stops
- Housing stability is the settled part. Large randomized trials show Housing First keeps people housed. That is the strongest, least-contested finding, and the National Academies agrees.
- Cost savings are strongest for the expensive cases. For chronically homeless people who cycle through jail and the ER, housing them cuts those bills, shown in the Denver trial. Population-wide, the National Academies calls the cost-offset evidence thinner. We claim the first, not the second.
- Average is not marginal. Vera warns that removing one prisoner does not save the full $33,274, because much of prison cost is fixed. The clean proof is the randomized reduction in actual jail and emergency use, not a subtraction on a spreadsheet.
- We leave the oversold numbers out. Utah's widely repeated “91% reduction in chronic homelessness” leaned on counting-definition changes and later rebounded. It is the kind of stat that discredits a real policy, so it is not part of this case.
The expensive option is the one that fails
The country spends more than $33,000 a year to hold one person in prison, and most of them are rearrested within five years. It spends less to house someone, and the housing tends to end while the jail cost refills itself. The “we can't afford to house people” objection is choosing the more expensive path on purpose. That is the double standard the Austerity Myth hub documents across every program.
Questions worth taking seriously
Doesn't Housing First just enable addiction by giving housing with no strings?
The no-preconditions design is the point, and the randomized evidence tests it. Housing First improves housing stability and engagement with services without requiring sobriety first, and the trials do not show it worsening outcomes. The gains are measured in controlled studies, not assumed.
Does it actually save money?
For high-need, high-cost people, yes: the Denver randomized trial shows housing cuts jail, police, and emergency use. Population-wide, the National Academies says the cost-savings evidence is thinner. We claim the first and not the second, which is the honest version.
Isn't it cheaper to just jail people?
No. A year in state prison averages $33,274 and runs to $69,355 in New York, with city jails higher, while supportive housing costs about $10,000 to $25,000. Prison also refills itself: about 68% of people released are rearrested within three years. It is the expensive option that does not work.
