OPINION
In this appeal, we consider whether our decision in United States v. Grisel has retroactive effect. We conclude that it does, and we reverse the judgment of the district court.

I
Hector Reina-Rodriguez appeals the district court's denial of his 28 U.S.C. § 2255 motion to correct a federal sentencing enhancement imposed on account of his Utah conviction for burglarizing a "dwelling." Reina-Rodriguez was indicted in federal district court for illegal re-entry after deportation, in violation of 8 U.S.C. § 1326 and he pled guilty without a plea agreement.
Under the Sentencing Guidelines, a violation of 8 U.S.C. § 1326 has a base offense level of eight. U.S.S.G. § 2L1.2. The district court applied a 16-level enhancement because Reina-Rodriguez had previously been convicted of second-degree *1186 felony burglary in Utah  specifically, "burglary of a dwelling" under Utah Code Ann. § 76-6-202(2)  which the court concluded was a felony "crime of violence" under the Guidelines. See U.S.S.G. § 2L1.2(b)(1)(A)(ii) & n.1(B)(iii). Taking into account other adjustments and mitigating factors, the district court sentenced Reina-Rodriguez to 51 months, followed by 36 months of supervised release, and a $100 special assessment.
At his sentencing, Reina-Rodriguez objected to the 16-level enhancement. He conceded that he had been convicted of burglarizing a dwelling under Utah law. But he claimed the enhancement did not apply because "dwelling" was defined more broadly under Utah law, see Utah Code Annotated § 76-6-201(2),[1] than under the Guidelines and the record did not establish that the building he burglarized was a "dwelling" under the Guidelines. As a result, he argued, his Utah burglary conviction did not qualify as burglary of a dwelling under the Guidelines.
The district court disagreed. The judge told Reina-Rodriguez at sentencing that he had conducted a sua sponte investigation and had taken judicial notice of public property records in Weber County, Utah, which showed that the burglarized building was a single-resident building and, hence, a "dwelling" under the Guidelines. Thus, the court concluded, Reina-Rodriguez's conviction matched the Guidelines' definition of burglary.
After being sentenced, Reina-Rodriguez filed a Rule 35 motion to modify his sentence. See Fed.R.Crim.P. 35(a). He argued that the district court erred by not providing him notice of its sua sponte investigation or its reliance on the public property records. The district court denied the motion, concluding that any error was harmless.
Reina-Rodriguez filed a direct appeal, challenging the 16-level enhancement. A panel of our Court affirmed the district court. United States v. Reina-Rodriguez, 468 F.3d 1147 (9th Cir.2006). The panel concluded that it did not need to address the question of whether the district court correctly relied on the public property records. Id. at 1154 n. 8. Instead, the panel applied the categorical and modified categorical analysis first articulated in Taylor v. United States, 495 U.S. 575, 110 S.Ct. 2143, 109 L.Ed.2d 607 (1990),[2] and determined that "burglary of a dwelling under Utah law categorically fits the Guidelines' definition of burglary of a dwelling." Reina-Rodriguez, 468 F.3d at 1157. As part of its analysis, the panel reasoned that structures adapted for sleeping or lodging, which are "dwellings" under Utah law, categorically qualify as dwellings under the Guidelines. See id. at 1156-57. Thus, the panel concluded, the *1187 district court correctly applied the 16-level enhancement.
After the panel affirmed the district court in Reina-Rodriguez, our Court issued an en banc opinion in United States v. Grisel, 488 F.3d 844 (9th Cir.2007) (en banc). In Grisel, we overruled Reina-Rodriguez and other decisions "to the extent that [they] suggest[ed] that state statutes satisfy [Taylor's] categorical inquiry when they define burglary to include non-buildings adapted for overnight accommodation...." 488 F.3d at 851 n. 5. After Grisel, courts must utilize the modified categorical approach to determine whether a "dwelling" in Utah meets the Guidelines' definition of "dwelling." See id. A non-building adapted for accommodation  e.g., a vehicle or boat  may still qualify as a "dwelling" under the Guidelines, but "it does not do so categorically." Id.
In light of Grisel, Reina-Rodriguez filed a motion with the district court under 28 U.S.C. § 2255, asking it to vacate, set aside, and correct his sentence. He argued that Grisel should be applied retroactively and that his conviction should be set aside because "the Grisel court specifically overruled the previous Reina-Rodriguez panel's opinion." The district court denied the motion because Reina-Rodriguez did not "establish that the decision in Grisel should operate retroactively or that Grisel provides him any relief."
Reina-Rodriguez moved for reconsideration, but the district court denied that motion, as well. The district court acknowledged that Grisel overruled Reina-Rodriguez, at least in part: "[A]fter Grisel, a modified categorical analysis must be utilized in the Ninth Circuit to determine if there has been a crime of violence that involved a dwelling as defined by Grisel." But, the court reasoned, both it and we had met the dictates of the new rule by applying a modified categorical approach.
Reina-Rodriguez requested a certificate of appealability, but the district court denied the request. Among other reasons, it concluded that "the issues raised in the COA have previously been addressed to, seriously considered by, and resolved against this Court and the Ninth Circuit Court of Appeals." We, however, granted Reina-Rodriguez's request for a certificate of appealability with respect to the question of "whether appellant's sentence is unlawful based on his sentencing enhancement for a prior crime of violence based on a Utah burglary conviction."
We have jurisdiction, under 28 U.S.C. § 2253, to review the district court's denial of Reina-Rodriguez's § 2255 motion and his motion for reconsideration. We review de novo: (1) the district court's denial of a 28 U.S.C. § 2255 motion, United States v. Gamba, 541 F.3d 895, 898 (9th Cir.2008); (2) the district court's interpretation of the Sentencing Guidelines, United States v. Salazar-Mojica, 634 F.3d 1070, 1072 (9th Cir.2011); and (3) all other questions of law, United States v. Millis, 621 F.3d 914, 916 (9th Cir.2010).

II
Generally speaking, new constitutional rules of criminal procedure do not operate retroactively for cases filed by state prisoners[3] seeking collateral federal habeas relief. Teague v. Lane, 489 U.S. 288, 310, 109 S.Ct. 1060, 103 L.Ed.2d 334 (1989). The primary question in this case is whether Teague precludes retroactive application of Grisel. We conclude that it does not.
*1188 The threshold questions for Teague application are whether the articulated rule is (1) a new constitutional rule and (2) procedural or substantive. If the threshold qualifications for Teague applicability are satisfied, there are two identified additional exceptions to the doctrine. Beard v. Banks, 542 U.S. 406, 411, 124 S.Ct. 2504, 159 L.Ed.2d 494 (2004) (citations and internal quotation marks omitted). The first Teague exception that the Supreme Court has described is for "rules forbidding punishment of certain primary conduct [or to] rules prohibiting a certain category of punishment for a class of defendants because of their status or offense." Id. at 416, 124 S.Ct. 2504 (citations and internal quotation marks omitted). However, as the Supreme Court has noted, rules falling under this "exception" are "more accurately characterized as substantive rules not subject to the bar." Schriro v. Summerlin, 542 U.S. 348, 352 n. 4, 124 S.Ct. 2519, 159 L.Ed.2d 442 (2004). In other words, what has been categorized traditionally as an exception is a restatement of the threshold requirement that the new rule be procedural rather than substantive. See Beard, 542 U.S. at 411 n. 3, 124 S.Ct. 2504 (citations and internal quotation marks omitted).
Under the second exception, Teague does not apply to "watershed rules of criminal procedure implicating the fundamental fairness and accuracy of the criminal proceeding." Id. at 417, 124 S.Ct. 2504 (citations and internal quotation marks omitted).
There are several reasons why Teague does not apply to Grisel.

A
First, Teague applies only to "new constitutional rules of criminal procedure." Danforth v. Minnesota, 552 U.S. 264, 274, 128 S.Ct. 1029, 169 L.Ed.2d 859 (2008) (quoting Teague, 489 U.S. at 310, 109 S.Ct. 1060) (emphasis added). If the new rule is not founded on constitutional concerns, it does not implicate Teague. See, e.g., United States v. Talk, 158 F.3d 1064, 1071 (10th Cir.1998) (concluding that retroactive application of a decision was not Teague barred because the decision was "neither new nor constitutional.... [The] prescriptions [of the decision] are not constitutional."), abrogated on other grounds as recognized in United States v. Harms, 371 F.3d 1208, 1210 (10th Cir. 2004); Oliver v. United States, 90 F.3d 177, 179 (6th Cir.1996) ("Teague stands for the proposition that new constitutional rules of criminal procedure will not be announced or applied on collateral review" (quotation marks and citation omitted)).
Here, Reina-Rodriguez seeks to avail himself of a rule from Grisel that limits the definition of burglary under the Armed Career Criminal Act. Grisel is a new rule. See Whorton v. Bockting, 549 U.S. 406, 416, 127 S.Ct. 1173, 167 L.Ed.2d 1 (2007) ("The explicit overruling of an earlier holding no doubt creates a new rule." (quoting Saffle v. Parks, 494 U.S. 484, 488, 110 S.Ct. 1257, 108 L.Ed.2d 415 (1990))). But it is not a new constitutional rule, since it does not implicate constitutional rights. The rule simply delimits the conduct that qualifies as burglary under Taylor's categorical-approach analysis. As a result, Teague's retroactivity bar does not apply.

B
Second, as we have previously explained, a "threshold question in a Teague analysis is whether the rule that the petitioner seeks to apply is a substantive rule or a procedural rule, because `Teague by its terms applies only to procedural rules.' Bousley v. United States, 523 U.S. 614, 620, 118 S.Ct. 1604, 140 L.Ed.2d 828 (1998)." Hayes v. Brown, 399 F.3d 972, *1189 982 (9th Cir.2005). "New substantive rules generally apply retroactively." Summerlin, 542 U.S. at 351, 124 S.Ct. 2519.
"For Teague purposes, a new rule is one of `procedure' if it affects the operation of the criminal trial process, and a new rule is one of `substance' if it alters the scope or modifies the applicability of a substantive criminal statute." Hayes, 399 F.3d at 982 (citing Bousley, 523 U.S. at 620, 118 S.Ct. 1604). Substantive rules "include[] decisions that narrow the scope of a criminal statute by interpreting its terms...." Summerlin, 542 U.S. at 351, 124 S.Ct. 2519.
In Grisel, we considered the scope of a state criminal statute, Or.Rev.Stat. § 164.215(1), in the context of ascertaining the scope of a federal criminal statute, 18 U.S.C. § 922(e). See 488 F.3d at 845. In doing so, we carefully examined the statutory history, congressional intent, and Supreme Court construction of the federal statute. Id. at 847-49. We concluded that "second-degree burglary under Oregon law is not a categorical burglary for purposes of the [Armed Career Criminal Act]...." Id. at 851. One could hardly have a clearer example of a "decision[] that narrow[s] the scope of a criminal statute by interpreting its terms...." Summerlin, 542 U.S. at 351, 124 S.Ct. 2519; see also United States v. Shipp, 589 F.3d 1084, 1091 (10th Cir.2009) (holding that the Supreme Court's construction of the scope of the Armed Career Criminal Act was a decision of substance, entitled to retroactive effect in federal habeas proceedings).
Grisel was grounded in substantive law, not criminal procedure. In short, as the Supreme Court has instructed, Teague's anti-retroactivity principle "is inapplicable to the situation in which this Court decides the meaning of a criminal statute enacted by Congress." Bousley, 523 U.S. at 620, 118 S.Ct. 1604. As such, Teague does not apply here.
The Government's arguments to the contrary are not persuasive. The Government first remarks that Grisel "did not alter the range of conduct or the class of persons that Utah law may punish for second degree burglary." Of course it did not, but that is quite beside the point. Grisel altered the punishment that can be imposed on federal defendants under the Armed Career Criminal Act. Under Grisel, federal courts can no longer categorically enhance a sentence for such defendants if the underlying state statute defines "burglary to include non-buildings adapted for overnight accommodation." 488 F.3d at 851 n. 5.
Second, the Government argues, "[T]he new rule [only] altered the permissible methods for determining" whether a sentencing enhancement can be imposed on account of a state burglary conviction. Not so. Grisel did not alter the procedural dimensions of Taylor's categorical approach. Rather, it altered the conduct that substantively qualifies as burglary under the categorical approach.
Because Grisel announced a substantive rule, rather than a procedural one, Teague does not bar retroactive application of Grisel.

C
Although we need not, and do not, reach this question, we must note before leaving our discussion of Teague that there is some doubt under current Supreme Court jurisprudence whether Teague applies to federal prisoners, such as Reina-Rodriguez, who seek federal habeas relief. As Chief Justice Rehnquist noted, the Teague rule was "motivated by a respect for the States' strong interest in the finality of criminal convictions, and the recognition that a State should not be penalized for *1190 relying on `the constitutional standards that prevailed at the time the original proceedings took place.'" Lockhart v. Fretwell, 506 U.S. 364, 372, 113 S.Ct. 838, 122 L.Ed.2d 180 (1993) (quoting Teague, 489 U.S. at 306, 109 S.Ct. 1060).
Recently, in Danforth, Justice Stevens discussed Teague at length and further amplified that "the text and reasoning of Justice O'Connor's opinion also illustrate that the rule was meant to apply only to federal courts considering habeas corpus petitions challenging state-court criminal convictions." 552 U.S. at 279, 128 S.Ct. 1029. To be sure, Danforth did not directly consider whether Teague applied to federal prisoners seeking federal habeas relief; it concerned a different question. However, as the Sixth Circuit has noted, there is now some doubt as to whether Teague applies to federal-prisoner petitioners. See Duncan v. United States, 552 F.3d 442, 444 n. 2 (6th Cir.2009) ("It is not entirely clear that Teague's framework is appropriate for federal habeas petitions under 18 U.S.C. § 2255 because many of the comity and federalism concerns animating Teague are lacking.... But it has been this Court's practice to apply Teague to § 2255 petitions, and we adhere to it today.").
After Lockhart, but prior to Danforth, we squarely held that Teague applied to federal prisoner petitioners. United States v. Sanchez-Cervantes, 282 F.3d 664, 667-68 (9th Cir.2002); see also United States v. Montalvo, 331 F.3d 1052, 1058 (9th Cir.2003) ("We have already held that Teague applies equally to sections 2254 and 2255 habeas cases." (citing Sanchez-Cervantes)). We need not consider in this case whether that holding requires re-examination in light of Danforth's construction of Teague  a question that we highlight, but leave for another day.

D
For the reasons we have discussed, Grisel applies to this case, and the district court erred in concluding otherwise. Grisel was a non-constitutional, substantive decision concerning the reach of a federal statute. Grisel overruled the prior holding in this case that the Utah conviction categorically qualified as a predicate offense under the Armed Career Criminal Act. That conclusion applies to this habeas proceeding, and the district court erred in concluding that it did not.

III
Having decided that the Utah burglary does not categorically qualify as a predicate offense, we must now decide whether the district court erred in its modified categorical analysis. Under that familiar examination, if the statute criminalizes conduct that would not constitute an aggravated felony under federal sentencing law, as is the case here, then the conviction may not be used for sentence enhancement unless the record includes "`documentation or judicially noticeable facts that clearly establish that the conviction is a predicate conviction for enhancement purposes.'" United States v. Rivera-Sanchez, 247 F.3d 905, 908 (9th Cir.2001) (en banc) (quoting United States v. Casarez-Bravo, 181 F.3d 1074, 1077 (9th Cir. 1999)), superseded on other grounds by U.S.S.G. § 2L1.2 cmt. n.4 (2002), as recognized in United States v. Narvaez-Gomez, 489 F.3d 970, 977 (9th Cir.2007). "`[I]f the statute and the judicially noticeable facts would allow the defendant to be convicted of an offense other than that defined as a qualifying offense by the guidelines, then the conviction does not qualify as a predicate offense.'" Rivera-Sanchez, 247 F.3d at 908 (quoting Casarez-Bravo, 181 F.3d at 1077).
*1191 Thus, the relevant inquiry is whether the judicially noticeable documents establish that the conviction necessarily includes all of the elements of the qualifying offense. Rosas-Castaneda v. Holder, 630 F.3d 881, 886 (9th Cir.2011). Judicially noticeable documents under the modified categorical approach include the "charging document, written plea agreement, transcript of plea colloquy, and any explicit factual finding by the trial judge to which the defendant assented," as well as other documents with sufficient indicia of reliability. Shepard v. United States, 544 U.S. 13, 16, 125 S.Ct. 1254, 161 L.Ed.2d 205 (2005); see also United States v. Snellenberger, 548 F.3d 699, 701-02 (9th Cir. 2008) (en banc) (per curiam).

A
With these considerations in mind, we must examine the judicially noticeable documents in this case and determine whether they establish that the defendant committed the "crime of burglary of a dwelling," as that crime has been generically defined. The generic definition of "burglary of a dwelling" under the Guidelines is the "`unlawful or unprivileged entry into, or remaining in, a building or other structure [that is a dwelling], with intent to commit a crime.'" United States v. Rodriguez-Rodriguez, 393 F.3d 849, 852 (9th Cir.2005) (quoting Taylor, 495 U.S. at 598, 110 S.Ct. 2143).
The salient question for us is whether the judicially noticeable documents in this case establish that the burglary was of a "dwelling." After Grisel, the modified categorical analysis requires courts to analyze the nature of the structure to determine whether it is a "dwelling" under the Guidelines. We have held that a person's residential house qualifies. See Reina-Rodriguez, 468 F.3d at 1154-58; United States v. Guerrero-Velasquez, 434 F.3d 1193, 1196-97 (9th Cir.2006); United States v. Matthews, 374 F.3d 872, 877-80 (9th Cir.2004); United States v. Wenner, 351 F.3d 969, 972-74 (9th Cir. 2003).
However, after Grisel  and contrary to our reasoning in this case on direct appeal  "a non-building adapted for overnight accommodation" no longer qualifies automatically as a "dwelling" under the Guidelines. Grisel, 488 F.3d at 851 n. 5. A non-building might qualify in some circumstances, but "it does not do so categorically." Id.

B
In this case there are five documents urged for our consideration: (1) the information; (2) the judgment; (3) the presentence report; (4) the district court's report of its sua sponte property investigation; and (5) a transcript of the state court plea colloquy. We conclude that the information and the judgment of conviction are documents that may properly be considered under the modified categorical approach. Shepard, 544 U.S. at 16, 125 S.Ct. 1254. However, the remainder of the documents cannot.

1
A district court may rely on an uncontroverted presentence report for purposes of a categorical analysis when "the issue is only whether the documents provided by the probation officer supported the fact of the ... conviction." United States v. Felix, 561 F.3d 1036, 1045 (9th Cir.2009) (emphasis added). But it is inappropriate to use a presentence report "to determine the type or character of the conviction." Id. (emphasis in original). Accordingly, a district court cannot rely on a presentence report when employing a modified categorical analysis. As we noted in United States v. Corona-Sanchez, 291 F.3d 1201, 1212 (9th Cir.2002) (en *1192 banc), "[A] presentence report reciting the facts of the crime is insufficient evidence to establish that the defendant pled guilty to the elements of the generic definition of a crime when the statute of conviction is broader than the generic definition." See also United States v. Potter, 895 F.2d 1231, 1237-38 (9th Cir.1990). Ascertaining whether Reina-Rodriguez's conviction under Utah Code Ann. § 76-6-202(2) qualifies as a "crime of violence" requires resort to the modified categorical approach; the contents of the presentence report, therefore, may not be consulted.

2
The district court also relied on its own independent examination of Utah property records in concluding that the defendant had committed the offense of burglary of a dwelling. At sentencing, the judge stated:
Furthermore, my office did a check of the public property records in Utah, which I think this court can take judicial notice of  I can take judicial notice of  in fact I think the documents can be considered judicially noticeable for purposes of enhancement, and those property transfer records for Weaver County Utah show that the address as listed in the indictment at 2521 Jamerci Avenue (ph) is, in fact, a single resident building. So Mr. Reina-Rodriguez appears to have been charged with the burglary of a residence. And by statute and by public records that is a dwelling, and therefore I think he committed a burglary, a crime of violence and should be enhanced by 16 levels.
The district court did not place the document in the record, so we have no means of reviewing it. It was not part of the presentence report, and the parties had no notice before sentencing that the court would consider it.
In any event, the court erred in considering the document  as the government concedes on appeal  and it cannot form part of a modified categorical analysis. A central thesis of Taylor is the avoidance of "subsequent evidentiary enquiries into the factual basis for the earlier conviction." Shepard, 544 U.S. at 20, 125 S.Ct. 1254. Such inquiries are the "evil Taylor sought to prevent  inquiries into the underlying facts that would essentially turn the sentencing hearings into mini-trials on the issue of whether the prior crimes were committed." Franklin, 235 F.3d at 1170 (quoting United States v. Bonat, 106 F.3d 1472, 1476 (9th Cir.1997)). Under Taylor, "respect for congressional intent and avoidance of collateral trials require that evidence of generic conviction be confined to records of the convicting court approaching the certainty of the record of conviction in a generic crime State." Shepard, 544 U.S. at 23, 125 S.Ct. 1254.
Thus, the "judicially noticeable documents" that are appropriate for consideration are materials such as the "charging document, written plea agreement, transcript of plea colloquy, and any explicit factual finding by the trial judge to which the defendant assented." Id. at 16, 125 S.Ct. 1254. We have held on numerous occasions that, under the modified categorical approach, courts are to conduct only a limited examination of "the record of conviction" to determine whether the defendant was convicted of the elements of the generically defined crime. See Espinoza-Morales, 621 F.3d at 1144; see also Young v. Holder, 634 F.3d 1014, 1019 (9th Cir. 2011); United States v. Moriel-Luna, 585 F.3d 1191, 1200 n. 7 (9th Cir.2009); Malta-Espinoza v. Gonzales, 478 F.3d 1080, 1082 (9th Cir.2007); Chang v. INS, 307 F.3d 1185, 1189 (9th Cir.2002), abrogated on other grounds, Nijhawan v. Holder, ___ U.S. ___, 129 S.Ct. 2294, 174 L.Ed.2d 22 (2009).
*1193 Neither the parties nor the court is permitted in a Taylor analysis of a past crime to develop new evidence outside the record of conviction to prove the underlying elements of the crime. Here, the public property records were clearly outside the record of conviction, and the district court erred by relying on them at sentencing.

3
On appeal, the government urges us to consider the transcript of the state court plea colloquy. However, it did not present this document to the district court, and it is not part of the district court record. We decline to supplement the record on appeal. First, we rarely take judicial notice of facts presented for the first time on appeal. United States v. Torres-Flores, 502 F.3d 885, 894 (9th Cir. 2007) (citations omitted). Second, we take judicial notice of a fact only if it is "not subject to reasonable dispute." Id. (citing Fed.R.Evid. 201(b)). Here, the language of the colloquy is subject to varying interpretations, and there is a reasonable dispute as to what the plea colloquy establishes. Finally, and most importantly, it is not within our province to sentence the defendant based on considerations outside the sentencing decision. Appellate courts are not sentencing courts. These questions are best left to the sentencing court for consideration in the first instance. Thus, we decline the government's invitation to consider material outside the district court record and deny its motion to supplement the record.

IV
Because our decision in Grisel was a non-constitutional decision of substantive law, it applies retroactively. Under Grisel, the defendant's burglary conviction does not qualify categorically as a predicate offense. All but two of the documents tendered for our consideration in the modified categorical approach do not qualify as judicially noticeable documents under Shepard. The two remaining documents require reexamination through the lens of Grisel and its progeny.
We reverse the district court and remand for resentencing on an open record. United States v. Matthews, 278 F.3d 880, 885 (9th Cir.2002) (en banc).
VACATED and REMANDED.
NOTES
[*]  The Honorable Nancy Gertner, District Judge for the U.S. District Court for Massachusetts, Boston, sitting by designation. Judge Gertner retired from the judiciary on September 1, 2011, but concurred in the opinion prior to her retirement.
[1]  Under Utah Code Annotated § 76-6-201(2), "[d]welling" means a building that is usually occupied by a person lodging in the building at night, whether or not a person is actually present.
[2]  To determine whether a prior conviction qualifies as a "crime of violence" under U.S.S.G. § 2L1.2, we first apply the "categorical approach." United States v. Espinoza-Morales, 621 F.3d 1141, 1144 (9th Cir.2010).

Under that approach, we first consider whether a prior offense is categorically a crime of violence by assessing whether the full range of conduct covered by the statute falls within the meaning of that term. If the statute of conviction is overbroad  that is, if it punishes some conduct that qualifies as a crime of violence and some conduct that does not  it does not categorically constitute a crime of violence. In that case, we must then apply the "modified categorical approach" to determine whether the record of conviction shows that the defendant was convicted of the elements of the generically defined crime.
