Private Home Detention in Maryland: How “The Box” Works in Criminal Cases
If you’ve spent any time around Maryland criminal courts, you’ve probably heard somebody mention “the box.” It sounds vaguely ominous, but it’s really just shorthand for private home detention: a GPS ankle monitor strapped to your leg that tracks your location and reports back to a monitoring company.
The box shows up in two very different places in a Maryland criminal case: before trial as a condition of bond, and after a conviction as a sentencing alternative to jail. The rules, the cost, and who pays are not the same in each stage. Here’s how it actually works.
What Private Home Detention Actually Is
Private home detention is supervised, electronically monitored confinement at your home, run by a company licensed under Title 20 of the Maryland Business Occupations and Professions Article. The court orders it, a private monitoring agency installs a GPS unit on your ankle, and the agency reports violations (leaving the house, tampering with the monitor, missed check-ins) back to the court.
It is not a slap on the wrist. Under Maryland law, private home detention counts as “custodial confinement.” If you walk away from it or break the monitor, you can be charged with second degree escape, a misdemeanor carrying up to 3 years in prison and a $5,000 fine under Md. Code, Criminal Law § 9-405.
Pretrial Home Detention: The Box as a Bond Condition
Before trial, a judge can require private home detention as a condition of pretrial release. The statute is Md. Code, Criminal Procedure § 5-201(b), which allows the court to require a defendant to be monitored by a licensed private home detention monitoring agency as a condition of release.
This usually comes up in one of a few situations:
- The defendant is facing a serious charge and the court is not comfortable releasing them on a regular bond or personal recognizance alone
- The defense wants to give the judge a reason to release the client instead of holding them without bond
- The defendant has a history that makes the State argue they are a flight or public safety risk
If you get placed on pretrial home detention, the default rule is that you pay the monitoring agency directly. There is an important exception: if you qualify as indigent under § 16-210 of the Criminal Procedure Article, or if a monitoring device is provided by the State or a local jurisdiction, you cannot be required to pay the fee. When that happens, the State is supposed to use available federal funds to cover the costs.
In plain terms: pretrial home detention can be subsidized in certain cases. That’s a big deal, because the fees add up fast.

Post-Trial Home Detention: The Box as a Sentencing Alternative
After a conviction (or a probation before judgment), private home detention shows up in a completely different role: as a way to serve a sentence without sitting in a county jail cell.
Maryland law defines “custodial confinement” in several places, including Md. Code, Criminal Procedure §§ 6-219, 6-220, and 6-225. Under each of those sections, “custodial confinement” includes home detention, corrections options programs that require home detention or similar restrictions equivalent to confinement, and inpatient drug or alcohol treatment.
That definition matters because a judge can order a defendant to a term of custodial confinement as:
- A condition of a suspended sentence
- A condition of probation
- A condition of probation before judgment
So instead of doing 90 days at the local detention center, a judge might suspend that time and order 90 days of home detention on the box, with work or school release built in at the discretion of the Court. For people with jobs, kids, or medication regimens, that can be the difference between keeping their life together and losing everything.
Here’s the catch: post-trial, the defendant pays 100% of the cost. The indigency exception and federal funding subsidy in § 5-201(b) are tied to pretrial release. Once you are sentenced, the statute does not provide a similar state-paid backstop, and courts expect the defendant to cover the monitoring fees for the full term.

How Much Does the Box Actually Cost?
Private monitoring agencies in Maryland set their own rates, but the numbers clients typically see look something like:
- A one-time setup or installation fee, often a few hundred dollars
- A monthly monitoring fee of several hundred dollars per month
On a 90-day pretrial hold, that can easily add up to over a thousand dollars plus setup. On a 6-month post-trial sentence, you are easily talking about several thousand dollars out of pocket. Some agencies offer payment plans. None of them run for free.
Confirm current pricing directly with the specific agency the court assigns, because rates change and some counties use preferred vendor lists.
County Pretrial Services: The Free (But Limited) Alternative
Nearly every Maryland county has some form of jail-based pretrial services unit. These units are run by the county corrections department, not a private company. If the court orders you onto county pretrial supervision, there is usually no fee, or a much smaller administrative fee compared to private monitoring.
Sounds like an easy win, but there are real limits:
- Limited number of monitors. County pretrial programs only have so many GPS units. If the units are all out on other defendants, the program may not be able to take your client, no matter how good a candidate they are.
- Geographic restrictions. Some county pretrial programs will only supervise defendants who live in that county, or within a certain radius. If you were arrested in Prince George’s County but live in Baltimore County, the PG program may not accept you.
- Program-specific rules. Each county runs its program differently, with its own check-in requirements, curfews, drug testing protocols, and eligibility criteria. What flies in Howard County may not work in Anne Arundel.
- Competing demand. Judges in busy jurisdictions sometimes have to ration the limited county slots. Private home detention does not have that capacity problem; if you can pay, the box is available.

Rules While You’re on the Box
Whether pretrial or post-trial, the conditions are similar. You stay at your approved residence except for pre-approved movements (work, school, medical appointments, court, attorney visits, treatment). You charge the device every day. You check in with the monitoring agency on their schedule. You do not cut the strap.
Breaking those rules is not a minor issue. Under Md. Code, Criminal Law § 9-405, a person commits second degree escape when they:
- Violate any restriction on movement imposed under the home detention order or agreement
- Fail to return to the place of confinement
- Remove, block, deactivate, or tamper with the monitoring device, including an ankle or wrist bracelet or GPS tracker
Second degree escape carries up to 3 years in prison and a $5,000 fine. Under § 9-407, an escape sentence must run consecutive to the underlying sentence and cannot be suspended. Translation: if you cut the box off a 1-year home detention sentence and get caught, you can end up serving the original year plus escape time on top.

When the Box Actually Makes Sense
Private home detention is not the right fit for every case, but it can be a strong option when:
- You are facing pretrial detention and the judge needs a reason to release you on bond
- You have a job, kids, or medical needs that make jail time especially damaging
- County pretrial services cannot take you because of capacity or geography
- You are looking at a short jail sentence that a judge might be willing to convert to home detention
- You are seeking probation before judgment and need a credible alternative to incarceration
It is usually not a good fit when the defendant has no stable housing, cannot afford the fees, or has a history of non-compliance with electronic monitoring.

FAQs
Q: Who pays for private home detention in Maryland?
A: Pretrial, the defendant pays the monitoring agency directly under Md. Code, Criminal Procedure § 5-201(b)(2), unless the defendant qualifies as indigent under § 16-210 or the State or local jurisdiction provides the device. In those cases, available federal funds cover the fee. Post-trial, the defendant pays 100% of the cost.
Q: Is the box the same as county pretrial services?
A: No. “The box” usually refers to private home detention, a program run by a for-profit company licensed under Title 20 of the Business Occupations and Professions Article. County pretrial services are run by the county jail and are typically free, but they have capacity limits and geographic restrictions.
Q: Can I leave the house while on home detention?
A: Only for pre-approved purposes listed in your order or agreement, such as work, school, medical appointments, court, attorney visits, or treatment. Leaving without permission can be charged as second degree escape under Md. Code, Criminal Law § 9-405.
Q: What happens if I cut the ankle monitor off?
A: Tampering with, removing, or deactivating a monitoring device is second degree escape under Md. Code, Criminal Law § 9-405(b)(2)(iii). It is a misdemeanor punishable by up to 3 years in prison and a $5,000 fine, and under § 9-407 the sentence must run consecutive to the underlying sentence and cannot be suspended.
Q: Can home detention be ordered instead of jail as a sentence?
A: Yes. Under Md. Code, Criminal Procedure §§ 6-219, 6-220, and 6-225, a Maryland court can order “custodial confinement,” which includes home detention, as a condition of a suspended sentence, probation, or probation before judgment.
Q: Does time on home detention count against my sentence if I get violated?
A: Yes. Under § 6-219(f) of the Criminal Procedure Article, if you violate probation, any time already served in custodial confinement (including home detention) is credited against any sentence of incarceration the court imposes.
