OPINION OF THE COURT
Olgа Gaydos appeals her conviction for malicious destruction of property by means of fire, contending that the evidence at trial did not meet the interstate commerce nexus required under 18 U.S.C. § 844(i). She also argues that the district court faded to make the required findings to support her sentence and restitution order; and, that the district court improperly refused to reach the merits of her untimely post-trial motions for judgment of acquittal and for a new trial. We conclude that thе government failed to prove the jurisdictional element of 18 U.S.C. § 844(i), and will reverse her conviction on that count. We will also vacate the restitution order and remand the matter for the district court to make the required findings and, if indicated, enter a new order of restitution. In all other respects, we will affirm.
I.
Olga Gaydos owned a house located on Shadeland Avenue in Pittsburgh, Pennsylvania that she rented to William Minor, Jeannie McComb and their children. In December 1992, a fire of incendiary origin damаged its garage. Kenneth Evans testified that he saw David Minor (William Minor’s brother) coming out of the garage at approximately the same time the garage was afire. There was also testimony that Gaydos offered two other tenants $15,000 each to bum down the house and that she had suggested starting a fire in the garage. Gaydos filed an insurance claim with her homeowner’s insurance carrier for damage to the garage and contents allegedly lost in the fire.
In June 1993, Fidelity Savings Bank began foreсlosure proceedings on the property. While the foreclosure proceedings were pending, Gaydos met with Jeannie McComb to discuss a lead contamination problem the Health Department had found at the Shade-land Avenue house. McComb testified that at this, meeting Gaydos told her that she (Gaydos) intended to burn down the house. Gaydos and McComb then supposedly struck a deal whereby Gaydos would allow McComb, William Minor, and their children, to move to another house wherе they could live rent-free if they remained silent about the fire Gaydos was planning for the Shade-land Avenue house.
Soon after, Gaydos discussed the lead problem with William Minor. According to Minor’s testimony, Gaydos told him that she did not want to put any money into the house to correct the lead problem. Gaydos also allegedly offered Minor $10,000 to burn down the house, which he refused. Minor, McComb and their children, did, however, leave the house and moved into another house owned by Gaydos. Approximately two weeks later, the Shadeland Avenue house burned to the ground in a fire determined to be of incendiary origin. Gaydos again submitted a claim to her homeowner’s insurance carrier.
*507 Gaydos was charged in a six count indictment alleging four counts of mail fraud in violation of 18 U.S.C. §§ 1341 and 1342 (Counts 1-4), one count of use of fire to commit a felony in violation of 18 U.S.C. §§ 844(h)(1) and (2) (Count 5), and one count of malicious destruction of property by means of fire in violation of 18 U.S.C. § 844(i) (Count 6). Her codefendant, David Minor, was charged in two of the mail fraud counts (Counts 1 and 2). Gaydos was found guilty on all counts and David Minor was acquitted of the two charges against him.
Gaydos was sentenced to 51 months in prison for mail fraud and malicious destruction of property by means of fire, and to 60 months for use of fire to commit a felony. The district court ordered the sentences to run consecutively for a total of 111 months, to be followed by supervised release for three years. The court also ordered restitution in thе amount of $190,139.42.
II.
Gaydos challenges her conviction for malicious destruction of property by means of fire, contending that there was insufficient evidence for the jury to conclude that the government had satisfied the jurisdictional element of 18 U.S.C. § 844(i), which requires the government to prove that the property was used in an activity affecting interstate commerce. She contends that a vacant and uninhabitable building, with neither prospect nor intention of being returned to the stream of commerce, cannot satisfy the interstate commerce nexus required for a conviction under § 844(i).
Gaydos also argues that the district court committed two sentencing errors. First, she asserts that a vacant and uninhabitable building cannot be characterized as a “dwelling” for purposes of Section 2K1.4(a)(l)(B) of the United States Sentencing Guidelines. Second, she contends that the district court did not make the findings of fact necessary to support the restitution order it imposed.
Gaydos’ final argument on appeal is her claim that the district court erred by finding that it lacked jurisdiction to consider her untimely post-trial motions for judgment of acquittal and for a new trial.
III.
Section 844(i) provides in pertinent part:
Whoever maliciously damages or destroys ... by means of fire or an explosive, any building, vehicle, or other real property or personal property used in interstate or foreign commerce or in any activity affecting interstate or foreign commerce shall be imprisoned for not more than twеnty years....
In
Russell v. United States,
Gaydos concedes that
Russell
clearly stands for the proposition that renting real estate is an activity which affects interstate commerce within the meaning' of § 844(i). She argues, however, that
Russell
is inappo-site. First, Gaydos asserts that the Supreme Court’s recent decision in
United States v. Lopez,
A.
Gaydos asserts that the district court lacked subject matter jurisdiction over her alleged offense because § 844(i) exceeds the authority of Congress to regulate commerce under the Commerce Clause. In support of her argument, Gaydos relies on the Supreme Court’s recent decision in Lopez. Lopez, she argues, stands for the proposition that criminal statutes that regulate activities affecting interstate commerce pass constitutional muster only where the regulated activity “substantially affects” interstate commerce.
In
Lopez,
the Supreme Court invalidated the Gun-Free School Zones Act of 1990, which made it a federal offense “for any individual knowingly to possess a firearm at a place that the individual knows, or has reasonable cause to believe, is a school zone.” 18 U.S.C. § 922(q)(2)(A) (1994);
Lopez,
514 U.S. at-,
Quickly disposing of the first two categories, the
Lopez
Court focused on the third category. The Court held that the statute could not “be sustained under our cases upholding regulations of activities that arise out of or are connected with a commercial transaction, which viewed in the aggregate, substantially affеcts interstate commerce.”
Id.
at-,
We conclude that
Lopez
does not render § 844(i) unconstitutional. Unlike the statute at issue in
Lopez,
§ 844(i) contains a jurisdictional element which ensures, on a case-by-ease basis, that the property in question must be “used in interstate or foreign commerce or in any activity affecting interstate or foreign commerce_” 18 U.S.C. § 844(i). The jurisdictional element in § 844(i) makes the holding in
Lopez
readily distinguishable.
See, e.g., United States v. McMasters,
We believe that Russell’s interpretation of § 844(i), and its holding, that the statute constitutionally regulates arson of business property that satisfies the requisite jurisdictional element, is still authoritative precedent. Accordingly, we join the other circuits which have concluded that § 844(i) remains constitutionally viable after
Lopez. See, e.g., McMasters,
B.
Gaydos’ best argument is that the evidence was insufficient to satisfy the interstate commerce nexus necessary to support her conviction under § 844(i) because the government could not prove beyond a reasonable doubt that the house on Shadeland Avenue was used, or intended to be used, in an activity affecting interstate commercе at the time of the fire. Gaydos did not preserve this issue for appeal by filing a timely motion for a judgment of acquittal, so we review the sufficiency of the evidence under a plain error standard.
United States v. Zolicoffer,
In
Zolicoffer,
we held that “the failure to prove one of the essential elements of a crime is the type of fundamental error which may be noticed by an appellate court notwithstanding the defendant’s failure to raise it in the district court.”
Russell
established that renting real estate is an activity that affects interstate commerce for purposes of § 844(i).
The government argues that a
temporary cessation
of activity at a business property does not place that property beyond the scope of § 844(i). Again, we agree. This argument has been accepted by every Court of Appeals that has addressed the issue.

*510
Moreover, courts in both the Fifth and the Ninth Circuits have held that the destruction of uncompleted commercial buddings by means of fire falls within the coverage of § 844(i).
See Patterson,
We note that in each of these cases, however, there was a clear intention that the property at issue either remain in, or return to, the stream of commerce. Indeed, despite the temporary removal of the rental or business properties from the commercial market, the trial records in these cases demonstrate that the particular properties were treated by their owners as if they had never left the stream of commerce. 2 Moreover, in the two cases involving partially completed commercial buildings, the courts relied on significant connections to out-of-state factors to satisfy the interstate commerce nexus required under § 844(i), factors which are not present in this case. 3
Here, we do not believe that the trial record could support the conclusion that the house on Shadeland Avenue either remained in, or was intended to return to, the stream of commerce. In reaching this conclusion, we are persuaded by a number of factors. First, the record clearly demonstrates that all tenants had vacated the house. Indeed, the property was unfit for human habitation. It was contaminated by lead, and Gaydos had removed permanent fixtures such as ceiling fans and Mtehen cabinets. Second, there is no evidence that Gaydos had any intent to improve the living conditions at the house. She undertook no significant abatement measures to correct the lead problem and expressly stated that she was not going to devote any money to fixing the house. Finally, there was no evidence to refute Gaydos’ contention that the house had been permanently removed from the rental market and *511 had no prospect of generating any future rental revenue.
We conclude that given the confluence of factors in this case, the house on Shadeland Avenue ceased to be a rental property before it was destroyed by fire. Consequently, we conclude that the evidence here was insufficient to establish that the house was involved in an activity affecting interstate commerce at the time of the fire. The status of the house as a rental property was “the interstate hook on which the government hung its argument.”
Martin,
We note that our decision here may be perceived to be in tension with the decision reached by the court in
Parsons,
which affirmed a jury’s finding that a vacant house used as rental property for two to three years before the fire and that, at the time of the arson, was insured as rental property, qualified as “rental property” for purposes of § 844(i).
See
The facts here, unlike those in Parsons, demonstrate that the property at issue was both vacant and uninhabitable at the time of the fire. Moreover, Gaydos expressed a clear intent not to take necessary measures to make the house habitable for future tenants. We conclude that a reasonable juror could not have done more than speculate that the house on Shadeland Avenue had a real prospect of generating any future rental revenue.
In sum, we hold that the government could not prove beyond a reasonable doubt that the house on Shadeland Avenue was used in an activity affecting interstate commerce. Consequently, we will reverse Gaydos’ conviction for malicious destruction of property by mеans of fire in violation of 18 U.S.C. § 844(i). 4 •
IV.
Gaydos also challenges the restitution order entered by the district court. More specifically, Gaydos alleges that the district court failed to make the required findings of fact that she had the ability to pay before it entered a restitution order against her. We agree.
In ordering Gaydos to pay $190,139.42 in restitution, the district court relied on a listing of Gaydos’ assets contained in the pre-sentence report. At the sentencing hearing, however, both Gaydos and her counsel raised doubts concerning her ability to pay restitution. The district court never made specific factual findings with respect to these contentions. Rather, the court settled the issue by agreeing to a proposal by counsel for the government that, if necessary, the amount of restitution ordered could be remitted at a later date.
We have held that specific findings of fact regarding a defendant’s ability to pay are required before a restitution order may be imposed.
See, e.g., United States v. Maurello,
V.
Gaydos’ final argument is that the district court erred by refusing to reach the merits of her untimely post-trial motions for judgments of acquittal and a new trial. Federal Rule of Criminal Procedure 29(c) states in pertinent part, “[I]f the jury returns a verdict of guilty ... a motion for judgment of acquittal may be made ... within 7 days after the jury is discharged or within such further time as the court may fix during the 7-day period.” District courts are without discretion to consider untimely motions for judgment of acquittal under Rule 29(c).
Carlisle v. United States,
— U.S. -, -,
Similarly, Rule 33 requires that a motion for a new trial be filed “within 7 days after verdict or finding of guilty or within such further time as the court may fix during the 7-day period.” We have held that the time limit for filing motions for a new trial under Rule 33 is jurisdictional.
United States v. Coleman,
VI.
In summary, we will reverse Gaydos’ conviction under 18 U.S.C. § 844(i), vacate her sentence and restitution order, and remand the cause to the district court.
Notes
.
See Martin,
.
See, e.g., Martin,
.
See Patterson,
. At sentencing, Gaydos’ convictions for mail fraud (Counts 1-4) and for malicious destruction of prоperty by means of fire (Count 6) were grouped together and assigned a base offense level of 24 pursuant to U.S.S.G. § 2K1.4(a)(1)(B) (destruction of a "dwelling” by fire). Gaydos argues that because the house was vacant, uninhabitable, and without prospect of future rental, it was not a “dwelling” within the meaning of § 2K1.4(a)(l)(B). Instead, Gaydos asserts that her base offense level for these Counts should have been 20 pursuant to U.S.S.G. § 2K1.4(a)(2)(B) (destruction of a structure other than a dwelling). We need not reach the merits of Gaydos' contention because our reversal of her conviction on Count 6 requires the district court to readjust its application of the grouping rules and to recalculate Gaydos’ sentence.
. Gaydos also contends that the district court erred by failing to hold a factual hearing so that we could rule directly on the merits of her ineffectiveness of counsel claims. We have emphasized our preference that claims of ineffectiveness of counsel be raised in a collateral proceeding under 28 U.S.C. § 2255.
