In this nеgligence action, the plaintiff alleged that the defendants’ failure to shovel the sidewalk abutting their property had caused him to fall and injure himself. The trial court concluded that there was no issue of material fact and that, as a matter of law, the defendants owed the plaintiff no duty to remove the snow and ice from the public sidewalk abutting their property. Accordingly, the court granted the defendants’ motion for summary judgment. The court of appeals affirmed,
I.
On March 4, 1981, at approximately ten o’clock in the morning, the plaintiff, Joseph W. Bittlе, was walking on a public sidewalk in front of the commercial property owned by the defendants. 1 The City and County of Denver (the City) owned the public sidewalk. The defendants, their tenants, and the City each had failed to make any effort *51 to remove the snow and ice from the sidewalk after the most recent snowfall. Bittle slipped on a coating of snow and ice and fell, injuring himself. He alleged that as a result of the fall, he incurred over $7,000 in actual expenses and lost earnings, as well as $100,000 in pain and suffering and future expenses.
The plaintiff contended that the defendants had a common law duty to maintain the sidewalks abutting their property in a reasonably safe condition. Based on an ordinance whiсh required the defendants to remove snow and ice from the public sidewalks adjoining their property immediately after every snowfall, he also argued that the defendants were liable under the doctrine of negligence per se. The defendants responded that the municipality, rather than the abutting property owner, had the primary duty to keep the public sidewalks in reasonably safe condition. The defendants also argued that the ordinance cited by the plaintiff did not impose a duty to the plaintiff on the defendants. Citing this court’s prior decisions, both the trial court and the court of appeals concluded that the defendants had no duty to the plaintiff, either undér the doctrine of negligenсe per se or under the common law.
See Kanter v. City & County of Denver,
II.
We first consider the question of whether commercial property owners have a legal duly under the common law to keep the public sidewalks abutting their property reasonably clear of natural accumulations of snow and ice. The plaintiff makes a two-pronged attack on the lower courts’ decisions on this question. First, he attempts to distinguish
W.T. Grant Co. v. Casady,
A.
In
Grant,
we decided that, under the common law, the abutting property owner had no duty to keep public sidewalks reasonably free of snow and ice. Bittle argues that
Grant
does not apply to his complaint because in
Grant
the abutting property owner had used reasonable care. 117 Colo, at 409,
In addition, the Grant rationale has since been applied in a variety of circumstances, making it clear that under Colorado’s common law, property owners owe no duty to pedestrians to keep the sidewalks abutting their property reasonably clear of naturally accumulating snow and ice. 2 The “no duty” rule is firmly embedded in Colorado’s *52 jurisprudence and is not limited to the exact fact pаttern in Grant.
B.
The no duty rule is the common law rule in the majority of jurisdictions.

Annotation,

C.
Our (common law no duty rule is also consistent with our general tort law in three important respects. First, we always have recognized the importance of ownership in determining an individual’s responsibilities.
The question of whether a duty exists is a question of law, requiring consideration of a variety of factors.
See Smith v. City & County of Denver,
The plaintiff correctly notes that we have imposed a duty on owners of property to act reasonably in light of the foreseeability of injury occurring on their property.
See Mile High Fence Co. v. Radovich,
These cases, as well as
Palmer Park Gardens,
Second, absent a special relationship between a plaintiff and a defendant, we will not impose a duty on the defendant to take affirmative measures to prevent a harm to the plaintiff.
See, e.g., University of Denver v. Whitlock,
Finally, we generally have been unwilling to impose liability for injuries caused by natural obstacles or conditions.
See Smith v. City & County of Denver;
*54 D.
The plaintiff in this case urges us to overrule the well-established common law no duty rule in Colorado. He contends that the risk of a pedestrian being hurt on an icy sidewalk is substantial and the cost to the abutting owner is minimal, so it is unfair not to make abutting owners liable. This argument essentially asks us to shift the risk of injuries incurred on snowy and icy public sidewalks from the group of injured pedestrians who presently bear the burden to the group of people owning or occupying private property abutting public sidewalks. The plaintiff has not pointed to any relevant difference between these two groups which could justify such judicial burden shifting, and we see none. The plaintiff does suggest that we distinguish bеtween commercial and noncommercial property owners, apparently to address this problem. However, as the amicus notes, there is no legitimate basis for such a distinction.
We recognize that New Jersey has decided that a commercial landowner’s failure to remove snow and ice from the adjacent sidewalk after actual or constructive notice can be the basis for civil liability.

See Mirza,
The New Jersey decisions illustrate some of the problems that can arise when courts attempt to make these types of policy decisions without guidance from the legislature. First, the New Jersey Supreme Court limited the liability to owners of commercial property, even though it conceded that all property owners, residential as well as commercial, have special interests in the sidewalks abutting their property and that “whether the ownership ... is commercial or residential matters little to the injured pedestrian.”
Stewart,
To summarize, there is no basis in our common law for distinguishing between commercial and residential property for these purposes. The development of New Jersey law following Stewart shows the lack of wisdom of courts entering into this policy-making arena without any legislative guidance. Therefore, we decline to follow the New Jersey approach.
*55 E.
For the reasons stated above, we reaffirm our holding in Grant that owners of property have no common law duty to remove naturally accumulating snow and ice from the public sidewalks abutting their property. This rule is a well-established part of the common law in Colorado and elsewhere, and it is consistent with other areas of negligence law in Colorado. Any necessary changes in this rule must come from the state legislature or the municipal government.
III.
The plaintiff argues that the defendants’ violation of Revised Municipal Code of the City and County of Denver, Colorado (the Code), section 352.10-1 (1950 & rev. 1975), was negligence per se. Section 352.10-1 provided that:
The owner, occupant, or agent of the owner of any building[,] property, or vacant lot in the City and County of Denver is required to maintain the sidewalks, the parking, and the curbs, i.e., the area from the properly line to the gutter, adjoining said building, property, or vacant lot in a clean condition and to remove snow and ice from adjoining sidewalks immediately after every snowfall. 7
The defendants argue that this snow removal ordinance cannot be the basis for civil liability because it is penal in nature. Alternatively, they contend that the City cannot shift its duty to third parties and that the ordinance is intended to benefit only the City, not pedestrians.
A.
The defendants’ contention that a penal ordinance cannot be the basis for negligence per se is overbroad. In order to establish negligence per se, the plaintiff must show that he is a member of the class which the statute or ordinance was intended to protect and that his injuries are of the type it was enacted to prevent.
See, e.g., Largo Corp. v. Crespin,
The use of the doctrine of negligence per se when a municipal law does not explicitly provide for civil liability is not a recent development.
See, e.g., Lambotte v. Payton,
In Grant, we decided only that a violation of the particular penal ordinance in question was not negligence per se. The discussion above should make clear that the fact that an ordinance is penal in nature does not preclude application of the doctrine of negligence per se.
*56 B.
The defendants also assert that a municipality cannot shift its duty to maintain safe sidewalks to private individuals or entitiеs. It is true that a municipality cannot shift its governmental authority to people or entities who are unaccountable to the voters.
See City & County of Denver v. Denver Firefighters Local 858,
By imposing a duty on the landowner, the City is attempting to perform its duty, not to avoid it. This approach is clearly within the municipality’s authority.
See
§ 31-15-702(1)(a)(III), 12B C.R.S. (1986) (municipality has power “to require the owner or occupant of any premises to keеp the sidewalks ... free from snow”).
See generally
19 E. McQuillin,
supra,
§ 54.84 (3d ed. rev. vol. 1985) (municipality can impose duty to remove snow on abutting landowner). We previously have upheld municipal action requiring a property owner to pay the costs of construction and maintenance of sidewalks and other public improvements pursuant to section 31-15-702, because the abutting property owner is “especially benefited by the improvements over and above the general benefit to the public at large.”
Bethlehem Evangelical Lutheran Church v. City of Lakewood,
In
Grant,
we stated that a municipality could not avoid or suspend its duty to keep public sidewalks reasonably safe. We then explained that we were not “determinpng] whether the municipality could legally impose a civil liability for [the] violation [of the snow removal ordinance], but in any event it has not, by this section, attempted to do so.” 117 Colo, at 412,
C.
The majority rule is that violation of a snow removal ordinance is not negligence per se. This apparent exception to the negligence per se doctrine most frequently has been justified by explaining that snow removal ordinances are intended to benefit the municipality by helping it to perform its duty to keep the public sidewalks safe. Undеr this theory, because the ordinances are enacted primarily for the benefit of the community as a whole, and individual pedestrians are only indirect beneficiaries, all the requirements for negligence per se are not satisfied. See 19 E. McQuillin, supra, § 54.84; Restatement, supra, § 288(c) & comment d.
Other commentators have offered a variety of justifications for treating snow removal ordinances differently from other safety statutes and ordinances for purposes of negligence per se. For example, in The Role of Criminal Statutes in Negligence Actions, Clarence Morris discusses the cases declining to impose negligence per se for the violation of a snow removal ordinance and other areas where the doc *57 trine has not been applied. He suggests the following analysis:
[Cjriminal legislation is neither binding nor irrelevant to the scope of civil liability, and ... civil courts have the problem of discriminating on a policy basis between (a) those cases in which civil liability should be extended by analogy to the criminal law, and (b) those cases in which it should remain unchanged even though the defendant has run afoul of the criminal law.
Morris, supra, at 25 (footnote omitted). Under Morris’ view, relevant factors might include whether a violation is a major or minor misdeed, id. at 27, and whether the criminal enactment imposes punishment in the absence of fault, id. at 28.
According to Prosser and Keeton, “the most satisfactory explanation” of the negligence per se cases is that the court voluntarily adоpts legislative standards when doing so furthers the policy underlying the statute. Under their approach, laws which are intended solely to protect the interest of the community at large should not result in negligence per se because that would not further the legislative purpose.
See
Pros-ser and Keeton,
supra,
§ 36 (giving as examples blue laws, snow removal ordinances, and auto registration statutes). Their legislative intent analysis focuses on the policies which the legislature intended to further, not on the remedies which it intended to provide.
Cf. Cort v. Ash,
Another approach was offered in Thayer, Public Wrong and Private Action, 27 Harv.L.Rev. 317 (1913-14), considered to be a classic article on this subject. Thayer distinguished between enactments prohibiting malfeasance and those prohibiting non-feasance. He concluded that civil liability should be imposed based on an enactment requiring action only when there was a common law duty to act; the enactment would then provide a more exact standard of care. Id. at 330-31. When, as in the sidewalk cases, there was no common law duty to act, the enactment should be understood to impose a duty only to the public as an entity, unless the legislature specifically provided a private remedy. Id. at 329-33. Yet another theory is that the courts imposed liability оn the municipality because the municipality was the best loss distributor in an era before liability insurance. James, Statutory Standards and Negligence. in Accident Cases, 11 La.L.Rev. 95, 116 (1950-51).
Although the reasoning is varied, the conclusion is almost universal — it is not fair or appropriate for courts to use snow removal ordinances to impose civil liability absent explicit instructions from the legislative branch of government.
D.
We have previously explained that “[i]n contrast to a statutory cause of action, the doctrine of negligence per se is a part of the common law, created by the courts.”
Largo Corp.,
Not every statute or ordinance will be held to establish a duty and a standard of care under the negligence per se doctrine. For example, we declined to hold that a statute requiring the industrial commission to inspect workplaces created a legally cognizable duty to employees.
Quintano v. Industrial Comm’n,
Here, while the fact that the Denver snow removal ordinance required property owners to shovel the public sidewalks is certainly an important factor in our analysis of whether a duty exists, it is not the only factor. We are not working on a blank slate and the well-established common law no duty rule cannot be ignored. While the ordinance obviously benefits pedestrians indirectly, in light of the common law no duty rule we conclude that the ordinance should be understood as one intended primarily to benefit the municipality by helping it to perform its duty to keep the public sidewalks safe. See generally 19 E. McQuillin, supra, § 54.84; Prosser and Keeton, supra, § 36 at 223; Restatement, supra, § 288(c) & comment d (snow removal ordinance used to illustrate rule that standard will not be adopted from legislation intended to impose on the actor a service which the government has undertaken to provide the public). The fact that the penalty imposed by the ordinance is unrelated to the amount it would cost the City to remove the snow does not, as the plaintiff suggests, preclude this interpretation.
Such an interpretation has several strengths. First, it gives due weight to our common law no duty rule. The plaintiff has not shown any relevant legal or factual changes subsequent to the development of the no duty rule. The hazards posed by snow and ice on sidewalks have not changed and snow removal methods have not changed appreciably. This situation is quite unlike
Largo Corp.,
Second, in
Grant
we stated that the purpose of the sidewalk ordinance clearly was “to eliminate a source of danger to pedestrians
by the imposition of a penalty.”
117 Colo, at 412,
We recognize that West Virginia and Pennsylvania have taken a different approach.
See, e.g., Fisher v. City of Philadelphia,
However, as explained above, because of the long history of the common law no duty rule and the absence of any changed сircumstances, we conclude that imposing negligence liability would do violence to people’s reasonable expectations for no legitimate reason. We therefore prefer the approach adopted in Oregon, which makes clear that a municipality can create a right of action against abutting owners “by express provision,” but that a snow removal ordinance imposing only a penalty does not change the common law no liability rule.
See Papen v. Karpow,
For the above reasons, we conclude that unless the municipal government or the General Assembly specifically states that property owners will be civilly liable for violation of a snow removal ordinance, we will continue to follow our common law no duty rule.
IV.
In conclusion, property owners have no common law duty to remove naturally accumulating snow and ice from public sidewalks abutting their property. Because the ordinance in question did not expressly provide for imposition of civil liability on violators, it did not create a duty to pedestrians and we will not use it as the basis for negligence per se.
We therefore affirm the court of appeals, which affirmed the district court’s grant of summary judgment in favor of the defendants.
Notes
. The plaintiff initially sued the owners, the occupants, and the City and County of Denver. John Does I-V were the owners’ tenants and occupied the commercial property. The plaintiff did not pursue his claims against them in this action. The plaintiff and the City and County of Denver reached an out-of-court settlement. Because the only claim before this court is the plaintiffs claim against the owners of the property adjacent to the sidewalk on which he fell, when we refer to "the defendants” we mean the owners of the property.
. See, e.g., Kanter,
. The scope of the duty of abutting owners or occupants under Pennsylvania law is not entirely clear.
Compare Starr,
. The amicus brief argues that the Denver Charter has been changed since our decision in Grant and that it no longer provides that the Department of Public Works has exclusive control over sidewalks. There is no question, however, that the City has retained ownership of the public sidewalks. The complaint stated that the sidewalk was a public street under the City’s management and control. See Revised Municipal Code of the City and County of Denver, Colorado (thе Code), §§ 320-21 (1950 & revs. 12-31-61 & 1966) (regulations for sidewalks on public right-of-ways); see also Code § 350 (1950 & rev. 1976) (showing that snow removal ordinance on which the plaintiff relies is an ordinance regulating "Maintenance and Care of Public Property"). See generally 10 E. McQuillin, supra, §§ 30.11, 30.62 (3d ed. rev. vol. 1981) (sidewalk is part of street). Because the City retained ownership, we need not address this "exclusive control" argument.
. The plaintiff contends that the current rule is unfair because if a property owner does not shovel the public sidewalk at all, he is immune from negligence liability, but if he shovels the public sidewalk negligently, he is liable. He cites no case law that supports his contention that one who shovels poorly will be liable, and we find none. We did note the absence of evidence that any “affirmative act" by the defendant had сaused the ice to form in
Kanter,
. Bittle contends that the West Virginia courts have imposed a similar duty on property owners. West Virginia has not modified the common law no duty rule; instead; it has determined that the relevant ordinances create liability. See discussion in part III.D, at 57-58.
. Section 352.10-1 did not include a specific penalty provision. The general penalty provision in effect at the time of the plaintiffs fall, Code, section 011.10 (1950 & rev. 4-30-58), stated that a fine and/or imprisonment could be imposed for the violation of a provision of the Code for which no specific penalty was provided. Neither that general penalty provision nor the snow removal ordinance made any mention of civil liability. No substantive changes in the snow removal ordinance have been made since Bittle fell. See Code, tit. II, ch. 49, art. VI, § 49-551 (1982 & supps. nos. 14 & 20).
