I. FACTUAL AND PROCEDURAL BACKGROUND

Omar Jahal Daggao (a.k.a. Omar Jahal Ali-Daggao) was charged with committing three armed bank robberies, and was arrested on August 27, 1992. He was held in custody until September 9, 1992, when he appeared before a United States magistrate for a bail hearing. The magistrate released Daggao on a $100,000 property bond with several conditions. It was ordered that Dag-gao be confined to his parents’ house, and electronically monitored. He was required to be confined at his parents’ house at all times, except to attend a local community college, and for other reasons authorized by Pretrial Services. Pursuant to this order, Pretrial Services authorized him to leave his parents’ house every Monday through Friday from 8:00 A.M. to 5:00 P.M. Daggao remained in such in-house detention for approximately seven and a half to eight months. 1

Prior to sentencing, Daggao requested a downward departure from his Guideline sentence under U.S.S.G. § 5K2.0 on the basis of the approximately eight-month period of in-house detention. The district court denied the downward departure, stating that it did not believe that it had authority to depart downward for time spent under in-house detention under § 5K2.0. When the prosecutor requested that the district court specifically hold that even if it did have such authority, it would deny the request for a downward departure, the district court refused. Daggao was sentenced to 87 months imprisonment, followed by five years supervised release. The 87 month sentence was the low end of the applicable guideline range, based on a total offense level of 27, and Daggao’s category III criminal history.

Daggao timely appealed the district court’s sentence, claiming that the court erred in finding that it lacked authority under U.S.S.G. § 5K2.0 to depart downward for time spent under in-house detention. We affirm.

II. DISCUSSION

We review de novo the district court’s decision that it lacked authority to grant a downward departure from the Sentencing Guidelines. United States v. Lira-Barraza, 941 F.2d 745, 746 (9th Cir.1991) (en banc).

Daggao claims that the district court erred in finding that it lacked authority to depart downward from the Sentencing Guidelines for time spent under in-house detention prior 'to sentencing. U.S.S.G. § 5K2.0 states:

If the district court identifies an aggravating or mitigating circumstance not adequately taken into account by the Commission, then “the court is legally authorized to depart so long as the circumstance is consistent with *987 the sentencing factors prescribed by Congress in 18 U.S.C. § 3558 (a), with the Guidelines, and, of course, with the Constitution.” Lira-Barraza, 941 F.2d at 746 .

To the extent that the Sentencing Commission has not considered the conditions or time under which a defendant i's released or detained before trial or sentencing, it is simply because a sentencing court lacks statutory authority to consider it as a factor at sentencing, as the Supreme Court held in United States v. Wilson, — U.S. —, 112 S.Ct. 1351 , 117 L.Ed.2d 593 (1992). In Wilson , the Supreme Court held that the district court has no authority to grant a defendant credit for any time served in detention before sentencing, but rather that the Attorney General has the sole authority to grant credit for time already served.

In United States v. Huss, 7 F.3d 1444, 1448-49 (9th Cir.1993), we upheld the district court’s finding that it lacked authority to depart downward from the Guidelines on the basis of time which the defendant had already spent in state custody. We found that authority to depart was precluded by the Supreme Court’s decision in Wilson . In doing so, we rejected the defendant’s argument that “he was not asking the district court to circumvent Wilson , but rather to credit Huss for time that he served that would not be recognized by the BOP.” Huss, 7 F.3d at 1449 . The court stated that credit for such time served could only be pursued in district court once the defendant had exhausted administrative remedies by challenging the decision of the Bureau of Prisons (BOP) not to grant credit. Id. Therefore we refused to reverse the district court’s determination that it lacked authority to depart downward for time spent in state custody.

Daggao is also trying to receive a downward departure for time for which the BOP will not grant credit. 2 While Daggao’s confinement involved time spent in pre-trial detention rather than time spent in state custody, this is not a meaningful distinction for purposes of U.S.S.G. § 5K2.0. Accordingly, if Wilson precludes granting a downward departure for time spent in state custody, it also precludes departure for time spent under pre-trial in-house detention.

Daggao claims that Huss is not dispositive because the court couched its opinion under the rationale that rather than ask for a downward departure for time spent in state custody, the defendant should have exhausted administrative remedies before appealing. The administrative remedy the court referred to was a challenge to the Attorney General’s sentencing policy, followed by a habeas corpus petition on that issue. 3 As Daggao recognizes, our opinion in Huss was focused on the power to grant credit, an administrative action which is generally left to the Attorney General. For this reason, we did not discuss whether pre-trial detention was considered by the Guidelines, or constitutes a mitigating circumstance warranting a downward departure.

Daggao claims that this court in Huss did not discuss whether pre-trial detention was considered by the Guidelines, or constitutes a mitigating circumstance, because Huss asked for a downward departure for the purpose of obtaining credit he would otherwise not receive. Huss, 7 F.3d at 1448-49 . Daggao argues that his claim is different in that he has made it clear he is not asking for credit, only that his detention be considered as a mitigating circumstance. This argument misses the point of our holding in Huss . We denied the downward departure in terms of authority to grant credit because we determined that it was improper to circumvent the Attorney General’s policies regarding when credit should be granted. Such policies should be directly attacked. Even though in this case Daggao is asking for downward *988 departure as “mitigation,” the result is that he wants credit for time served in the form of a downward departure. In Huss we determined that a district court lacks authority to depart downward for time served.

Daggao argues that this construction is undermined by this court’s decision in United States v. Miller, 991 F.2d 552 (9th Cir.1993). In that ease, this court held that it was proper for the district court to depart downward from the Guidelines because of six-months of home detention which the defendant had already served under an erroneous sentence. The court specifically held that Wilson was inapposite to the district court’s power to depart downward from the Sentencing Guidelines. Id. at 554 n. 2. However, the circumstances of Miller were different from those of the case at bar. The posture of the case in Miller was that the district court’s initial downward departure from the Guidelines was remanded by this court because the district court failed to adequately explain its reasons for departing from the Guidelines. When the district court reimposed the same sentence, one of the reasons it gave was that Miller had already served most of the original six-month home detention sentence, and it would be a “travesty” to make her serve the Guideline sentence at this point. This court agreed in part:

991 F.2d at 554 . We specifically stated that it is “the issue of compensating for time erroneously served” which the Commission had not considered. Id. In Daggao’s case, the time served was not as part of an erroneous sentence, but was merely a bail condition based on Daggao posing a risk of flight.

Instead of distinguishing this case from Huss , the appropriate distinction is between Huss and Miller. Miller is distinguishable from both Huss and Wilson on the ground that it involved someone who had already been sentenced, whereas in Wilson and Huss , the question was credit for time spent before sentencing. The holding of Miller is limited to the unique situation where time was served under an erroneous sentence. The quotation from United States v. Cook, 938 F.2d 149 (9th Cir.1991) which Judge Tang cites in his concurrence in Miller is instructive on this point: “[A] unique combination of factors may constitute [a mitigating] ‘circumstance’ ... the departure is to occur when ‘a court finds an atypical case,’ one ‘where conduct significantly differs from the norm.’ ” 991 F.2d at 555 (Tang, J., concurring in part and dissenting in part) (quoting Cook, 938 F.2d at 153 ). This court, as well as the Sentencing Guidelines, have made it clear that downward departures are to be reserved for “atypical” situations, and will be highly infrequent. See U.S.S.G. Part A4(b). While one might characterize as atypical the situation where a defendant is sentenced erroneously, and upon resentencing may not be given any credit for time served under house arrest, Daggao’s situation is not atypical.

Daggao’s claim is further undermined by this court’s rejection of a direct attack on the BOP’s credit policy regarding in-house detention. In Fraley v. United States Bureau of Prisons, 1 F.3d 924 (9th Cir.1993), we affirmed the dismissal of a habeas corpus petition which challenged the denial by the BOP of credit for time spent under house arrest prior to trial. In doing so, we recognized the different purposes of imprisonment in home confinement as a sentence compared to pre-trial in-house detention as a bond condition. Like Daggao, the defendant in Fra-ley was not permitted to leave her home without permission from the probation office, and was electronically monitored. We held that the defendant was not entitled to credit, as the conditions did not approach those of incarceration. Id. at 926 . We rejected an equal protection challenge based on people with sentences of less than six-months being allowed to serve their terms in home confine *989 ment. The court found that the defendant was not similarly situated, because of a different legal status. In contrast to those sentenced to home confinement, “pre-sen-tence residents are not being punished; they are conditionally released to [the halfway house] to protect the community and assure their presence at trial and sentencing.” Id. (quoting United States v. Woods, 888 F.2d 653, 656 (10th Cir.1989), cert. denied, 494 U.S. 1006 , 110 S.Ct. 1301 , 108 L.Ed.2d 478 (1990)).

Daggao argues that Fraley is distinguishable because Daggao does not claim that he is entitled to credit for time served under in-house detention, rather only that the circumstances of his pre-trial home detention may be considered as a mitigating circumstance upon which to base downward departure. While Daggao is correct that Fraley is not dispositive of the issue at bar, Fraley effectively undermines any rationale for allowing in-house pre-trial detention as a mitigating circumstance warranting downward departure. The only rationale for granting such a downward departure would be recognition of such confinement as punishment. However, in Fraley we held that pretrial in-house confinement does not serve as punishment, instead serving a separate purpose. “In contrast, pre-sentenced residents are not being punished.” 1 F.3d at 926 (quoting Woods, 888 F.2d at 656 ).

It would be inconsistent to hold that a defendant should be allowed a downward departure based on time spent under in-house detention in light of the finding that credit for such time served is not warranted, as this court held in Fraley . Pre-trial in-house detention serves a separate purpose from punishment, that of safeguarding the community, and assuring that the defendant is present at trial and sentencing.

III. CONCLUSION

We affirm the district court’s determination that it lacked the authority under U.S.S.G. § 5K2.0 to depart downward from the Sentencing Guidelines on the basis of time spent under in-house detention. The Attorney General has sole authority to grant credit for time served in detention before sentencing. That authority cannot be circumvented by allowing for downward departures under U.S.S.G. § 5K2.0, except under exceptional circumstances such as when a defendant is sentenced erroneously, and has served time under that erroneous sentence.

AFFIRMED.

. The Government alleges that Daggao violated his release conditions, while Daggao claims to have abided by these terms until he surrendered himself at the prison to serve his sentence. The record shows a few minor violations of the conditions of his release. However, in the Presen-tence Report, prepared just prior to sentencing and after the above reported incidents, it was reported that "[t]o date, the defendant has not violated any conditions of his pre-trial services supervision.” Because this was the report relied upon by the district court in making its sentence, we accept the conclusion of the probation officer that Daggao did not violate any conditions of his release.

. The Attorney General, in Program Statement No. 5880.24, has determined that for the purposes of granting credit towards a sentence served for days spent in "custody” under 18 U.S.C. § 3568 or "official detention” under its replacement 18 U.S.C. § 3585 , only time spent in physical incarceration or a jail-type institution or facility would be credited. Pre-trial detention in residence or a residential community center is not given credit.

. As noted infra, this court rejected such a challenge under circumstances similar to those of Daggao’s pre-trial detention in Fraley v. United States Bureau of Prisons, 1 F.3d 924 (9th Cir.1993).
