Private Prison Lockup Quotas: Contracts, Payments, and State Bans

Private prison lockup quotas are contract clauses that require a government agency to keep a privately run prison or detention center filled to a set percentage of its capacity, or to pay for the empty beds as though real people occupied them. A 2013 review of 62 private prison contracts found 65% contained these guarantees, with thresholds ranging from 80% to 100% of capacity.¹ The clauses shift the financial risk of falling incarceration rates from the operator to the taxpayer, and they have cost governments millions for beds no one slept in.

How the Guarantee Is Written Into the Contract

A lockup quota sits inside the service agreement between a government agency and a private operator. The contract fixes a total bed capacity for the facility, then names a percentage of those beds the government promises to fill or pay for each day. The operator charges a per diem rate per bed covering housing, food, staffing, and overhead, usually negotiated up front and adjusted annually for inflation or labor costs.

From the company’s side, the logic is about predictable revenue. Operators carry heavy upfront costs to build or renovate facilities, often financed through bond markets, and investors want assurance the facility will generate steady income regardless of crime trends or sentencing changes. The occupancy guarantee is that assurance: a revenue floor the company can show lenders. That is why these clauses tend to be non-negotiable once financing closes.

Some contracts use a tiered per diem, with a higher rate for each bed up to a guarantee threshold and a lower rate for beds above it.² The company earns its best margin on the guaranteed beds. The government, in turn, pays its highest rate on exactly the beds it is obligated to cover whether they are used or not. Occupancy is usually counted by a midnight headcount: whoever is in the facility at midnight is billed for that day.

Typical Guarantee Levels

Ninety percent is the most common threshold, though contracts range from 80% at the low end to 100% at the high end.¹ Put concretely: a 1,000-bed facility with a 90% quota means the government pays the full daily rate for 900 people even on a day when only 600 are actually incarcerated there.

The highest guarantees have shown up in a handful of states. Three Arizona facilities operated under 100% occupancy guarantees, with the state paying for every bed every day regardless of use.² Oklahoma carried three contracts at 98%, Louisiana had guarantees at 96%, and Virginia had one at 95%.¹ Detention centers for pretrial populations and immigration detainees sometimes carry different thresholds than long-term state prisons because their populations swing more and their operating costs differ. Facilities in remote locations or those providing specialized medical care tend to demand higher guarantees to offset steeper overhead.

What Governments Pay for Empty Beds

When the actual population falls below the guarantee, the government pays the per diem for every empty bed as though it were occupied. These payments are sometimes called ghost inmate fees or low-crime taxes. The math is straightforward: subtract the real headcount from the guaranteed minimum, multiply by the daily rate, and that is the bill for beds no one used.

In Colorado, where crime fell by roughly a third over the preceding decade, occupancy guarantees across three private prisons cost taxpayers an extra $2 million.¹ Arizona paid $3 million for empty beds at a single facility after the state stopped transferring inmates there following a 2010 escape.

At the federal level, Immigration and Customs Enforcement has shown the problem at scale. As of May 2020, ICE was paying for an average of 12,027 empty detention beds per day at a cost of roughly $20.5 million per month. At 11 facilities reviewed by the Government Accountability Office, ICE paid $41.2 million in a single month while using just 38% of the beds it had guaranteed.³ The GAO found ICE had not taken a strategic approach to setting those guaranteed minimums.

Operators argue the payments are necessary to keep facilities staffed, maintained, and ready to accept new arrivals on short notice. You cannot fire half the guards on Monday and rehire them Thursday when the population ticks up. But the fiscal pressure on agencies is real, and shortfall payments draw from the same general funds that pay for public safety, education, and rehabilitation.

How Quotas Shape Sentencing and Programming

Quotas affect more than budgets. A National Bureau of Economic Research study found that opening a new private prison increased sentence lengths in that state’s courts by about 1%, or roughly 14 additional days for the average sentence. The effect concentrated in the first two months after a facility opened, when vacant capacity was highest. Public prison openings produced no comparable effect.⁴

The researchers tested whether direct influence through campaign contributions or revolving-door hiring explained the pattern and found no evidence for it. The data pointed to a subtler mechanism: when private prisons reduce the perceived marginal cost of incarcerating one more person, judges hand down slightly longer sentences because the fiscal constraint feels less binding. The effect was twice as large in states that legally require private prisons to operate at least 10% cheaper than public facilities.⁴ Occupancy guarantees sharpen that dynamic by driving the marginal cost of an added inmate to effectively zero up to the quota.

Quotas also squeeze rehabilitation. At Ohio’s Lake Erie Correctional Institution, the operator converted space that had held prisoner re-entry classes into sleeping quarters for 300 additional beds to meet a 90% requirement. The result was overcrowding, triple bunking, and the loss of programs built to reduce recidivism.¹

Ohio’s North Coast Correctional Treatment Facility shows an even sharper mismatch. The facility was designed for nonviolent drunk-driving offenders, but a 95% bed guarantee for 700 beds forced the state to fill it even when it did not have enough of those offenders. To hit the quota, Ohio transferred people convicted of sexual battery, assault, arson, and robbery into a facility that was not built for them. The result was riots, safety breakdowns, and chronic staffing problems.¹ When the alternative is paying millions for empty beds, governments have repeatedly chosen the mismatch.

Federal Contracts and ICE

Federal use of lockup quotas has grown, driven mainly by ICE. From fiscal year 2017 to 2019, ICE increased its number of contracts with guaranteed minimums by 38%, from 29 to 43. The number of beds the agency guaranteed to pay for climbed from 19,342 to 28,043 over the same period, and ICE consistently failed to use all of them. The GAO noted that ICE added facilities with troubling performance histories to its guaranteed-minimum portfolio, including one previously under a Bureau of Prisons contract with chronic understaffing in correctional and health services.³

Federal policy has swung back and forth. In January 2021, President Biden signed Executive Order 14006, directing the Department of Justice not to renew contracts with privately operated criminal detention facilities. The order applied to the Bureau of Prisons and the U.S. Marshals Service but never covered ICE detention contracts. On January 20, 2025, President Trump revoked the order, reopening the door for the Bureau of Prisons and the Marshals Service to sign new contracts with private operators.⁵ The expansion of federal detention capacity and the return of Bureau of Prisons contracts mean federal-level lockup quotas are growing.

State Bans and Court Rulings

Several states have moved to ban private prisons or restrict minimum occupancy clauses. The result is a patchwork: an operator shut out of one state often builds in a neighboring state that still welcomes the contracts. Legislative approaches typically target the specific contract language that triggers payments for unoccupied beds, trying to eliminate the financial incentive to keep facilities full.

State bans run into a wall when they touch federal immigration enforcement. The Ninth Circuit Court of Appeals held in GEO Group, Inc. v. Newsom (2022) that federal immigration law preempted California’s private prison ban, meaning a state cannot prohibit a private company from running a facility that houses federal immigration detainees even if the state has banned private prisons entirely. The ruling carved out the fastest-growing category of private detention from state regulation.

Changing or Ending a Quota Contract

Contracts include ways to modify or end an occupancy guarantee, but the openings are narrow. A force majeure clause can suspend the quota during extraordinary events like natural disasters or pandemics that make high occupancy impossible or dangerous. Outside emergencies, governments typically have opt-out windows tied to the annual renewal cycle, when they can propose adjustments to the guaranteed minimums based on the prior year’s actual usage.

Renegotiating mid-contract usually requires formal written notice and documented evidence that conditions have changed, such as new sentencing laws or a sustained drop in the regional incarceration rate. Amendment provisions specify exact notification timelines, and missing those deadlines can automatically extend the existing quota for another year. Both parties must sign a formal addendum before any change takes effect.

Walking away entirely is harder still. The contracts run for years and sometimes decades: Ohio’s Lake Erie Correctional Institution agreement was a 20-year deal.¹ Early termination typically triggers substantial buyout costs negotiated into the original agreement, and those figures vary widely and are often sealed from public view. There is no standard industry range for termination penalties, because each deal is structured around its own financing, bond obligations, and remaining term. For many governments, the arithmetic turns out simpler than it should be: paying for empty beds year after year is cheaper than paying the lump sum to leave.
