Justice BRISTER

delivered the opinion of the Court,

in which Justice HECHT, Justice WAINWRIGHT, Justice MEDINA, and Justice WILLETT joined.

Must a landowner warn an independent contractor’s employees of obvious hazards they already know about? Four times in the last ten years this Court has said the answer is “No.”1 The plaintiff in this case argues that all these cases are wrong because his knowledge of the hazard is simply a factor the jury should consider in assessing comparative negligence. We agree the jury alone can decide whether he was negligent, but disagree that a jury can decide what legal duties landowners owe to independent contractors. We hold the trial court correctly found no duty here, and the court of appeals erred in reversing it.

I. Background

Arthur Lee Moritz worked for an independent contractor that delivered General Electric parts to customers. Every day for 18 months, Moritz drove his pick-up to GE’s warehouse, which had a loading dock with two large doors. Both doors were about four-and-a-half feet above the paved driveway, but only one had a concrete ramp extending down to grade level. The ramp was straight, 10 feet wide, 40 feet long, and had six-inch curbs along both edges but no guard rails. Generally, Mor-itz loaded supplies either by backing his truck up the ramp and into the warehouse itself, or backing up next to the door without a ramp. But on some days, he would load his truck on the ramp or outside in the driveway.

On the day Moritz was injured, both doors were blocked by GE supplies, so he parked his truck up on the ramp. Two GE employees helped him load electrical conduit into the bed of his pickup, after which Moritz alone secured the load with rachet-type straps. He then tried to add a rub*214ber bungee cord, but the cord broke while he was leaning back to stretch it, causing him to fall off the ramp’s side and fracture his hip, pelvis, and thumb.

Moritz sued GE and others,2 alleging that as owners or occupiers of the premises they were liable for negligence regarding activities and premises conditions.3 The trial court granted summary judgment for the defendants, but the court of appeals found fact questions as to both theories and reversed.4 We address each theory in turn.

II. The Negligent Activity Theory

Moritz alleged a negligent activity claim solely against GE. Generally, an owner or occupier does not owe a duty to ensure that independent contractors perform their work in a safe manner.5 But one who retains a right to control the contractor’s work may be held liable for negligence in exercising that right.6 This right to control may be expressed by contract or implied by conduct.7

In the summary judgment record here, there was no evidence Moritz’s duties were governed by a contract. There was some evidence that in practice GE controlled where Moritz could load his truck, such as when it blocked some of his loading options. But there was no evidence it controlled how or where Moritz secured his load for delivery — the truck, straps, and rubber cords he used for that purpose were entirely his own.

Citing our opinion in Lee Lewis Construction, Inc. v. Harrison,8 the court of appeals held that a fact question was created if “GE retained the right to control any aspect of Moritz’s activities.”9 What we actually said in Lee Lewis (citing the Restatement of Torts and numerous opinions) was that a defendant’s duty “is commensurate with the control it retains over the independent contractor’s work.”10 Thus, it is not enough to show that the defendant controlled one aspect of Moritz’s activities if his injury arose from another.11

Here, GE’s control of where Moritz could load supplies did not dictate where *215he could secure that load. While some loads undoubtedly must be secured before they are moved an incli, that was not the case here; Moritz admitted at his deposition that he could have driven off the ramp before securing this load. As an independent contractor, Moritz was free to choose whatever vehicle he wanted for deliveries, and when, where, and how he would secure his load. Thus, none of the defendants had contractual or actual control of Mor-itz’s decision to carry loads in the back of a pick-up truck or secure them with rubber cords requiring him to use his body weight to pull them taut.

Accordingly, the court of appeals erred in finding a fact question on his negligent activity theory.

III. The Premises Condition Theory

Moritz alleged a premises-condition claim against all the defendants. Generally, a landowner is liable to employees of an independent contractor only for claims arising from a pre-existing defect rather than from the contractor’s work,12 and then only if the pre-existing defect was concealed: “With respect to existing defects, an owner or occupier has a duty to inspect the premises and warn of concealed hazards the owner knows or should have known about.”13 Moritz’s claimed defect — the absence of rails on the loading ramp — was obviously a pre-existing condition and obviously not a concealed hazard.

Limiting premises liability to concealed hazards is not unique to cases involving independent contractors. A lessor who relinquishes possession or occupancy of premises also has no duty to warn of defects except those that are concealed.14 In both cases, the landowner’s duty is limited because control is being turned over to someone else in a way that is not true of shoppers, sightseers, or other business invitees.

An independent contractor owes its own employees a nondelegable duty to provide them a safe place to work, safe equipment to work with, and warn them of potential hazards;15 it also controls the details and methods of its own work, including the labor and equipment employed.16 Thus, one who hires an inde-*216pendent contractor generally expects the contractor to take into account any open and obvious premises defects in deciding how the work should be done, what equipment to use in doing it, and whether its workers need any warnings. Placing the duty on an independent contractor to warn its own employees or make safe open and obvious defects ensures that the party with the duty is the one with the ability to carry it out.

The dissent argues that it “makes no sense” to allocate duty in this manner because Moritz had no “control over the workplace conditions.” GE may have controlled Moritz’s loading options, but not where he chose to secure his load. Accordingly, it had a duty only to warn him of concealed defects he might encounter in doing his own work. The absence of handrails here was clearly not a concealed defect. If owners and occupiers have no duty to warn an independent contractor of open and obvious defects, the defendants had no duty to warn Moritz that the ramp he had been using for more than a year had no handrails.

IV. The Duty to Independent Contractors and Parker

The court of appeals held the defendants still owed Moritz a duty to warn or make the ramp safe because this Court abolished all no-duty arguments in 1976 in Parker v. Highland Park?17 But Parker does not go that far, as we explained more than 20 years ago in Dixon v. Van Waters and Rogers.18

In Parker, a landlord mis-set a timing device that turned on the lights in an enclosed stairway of an apartment building, darkening the tenants’ only way down.19 In upholding a jury verdict in a visitor’s favor, we “expressly abolish[ed] the so-called no-duty concept in this case” and ordered that “[t]he reasonableness of an actor’s conduct under the circumstances will be determined under principles of contributory negligence.”20

But Parker abolished a certain kind of no-duty defense, not all duty questions whatsoever. The question in Parker was not whether the defendant owed the plaintiff a duty; the landlord unquestionably had a duty to provide second-floor renters some way down besides jumping. The question instead, as we explained in 1984 in Dixon, was whether the plaintiff had to prove she had no knowledge of the stairway’s darkness as part of her case-in-chief:

The term “no-duty,” as used in Parker, referred to the oddity that had uniquely developed in Texas to confuse negligence law. It meant that a plaintiff had the burden to negate his own knowledge and his own appreciation of a danger. The rule that the plaintiff does not have the burden to obtain findings that disprove his own fault does not, however, mean that a plaintiff is excused from proving the defendant had a duty and breached it. A plaintiff does not have the burden to prove and obtain findings that he lacked knowledge and appreciation of a danger; he must, however, prove the defendant had a duty and breached it.21

*217Like any other negligence action, a defendant in a premises case is liable only to the extent it owes the plaintiff a legal duty.22 Whether such a duty exists is a question of law for the court;23 it is not for the jury to decide under comparative negligence or anything else. If (for example) a defendant neither owns nor occupies the premises, a jury cannot impose a duty anyway on the theory that Parker abolished all no-duty defenses. Every court that has analyzed Parker and Dixon together has come to this same conclusion — including courts of appeals for the First,24 Seventh,25 Eighth,26 and Fourteenth Districts,27 and the federal Fifth Circuit.28

We do not, as the overwrought dissent suggests, overrule Parker, comparative negligence, or principles of premises liability law “that govern virtually all other jurisdictions.” We acknowledge that GE had a duty to exercise care with respect to matters over which it exercised control, but it did not control where or how Moritz chose to secure his load. Unlike other invitees, independent contractors are hired for special projects that often entail special expertise,29 and can be expected to use whatever equipment or precautions are necessary so long as a hazard is not concealed. If Moritz wanted to use bungee cords and lean over backwards, that was his business; but he could not require GE to keep him safe no matter how he chose to do his own work.

Nor has it been “settled in our state for more than thirty years” that someone besides Moritz’s employer must owe him a duty here. We expressly rejected any such duty forty years ago. Before then, we had held in the 1920s in Galveston-Houston Elec. Ry. Co. v. Reinle that a premises owner had to warn employees of an independent contractor of a hazard even if the employee already knew about it.30 But in 1967, Chief Justice Calvert *218writing for this Court expressly overruled that decision:

Reirile must either be followed or overruled. With due respect for the rule of stare decisis, we are convinced that the rule of Reinle imposes an unfair and, indeed, an intolerable burden on an owner or occupier of land who employs an independent contractor to do work or to perform services on the premises. While an owner owes a duty to employees of an independent contractor to take reasonable precautions to protect them from hidden dangers on the premises or to warn them thereof, an adequate warning to or full knowledge by the independent contractor of the dangers should and will be held to discharge the landowner’s alternative duty to warn the employees.31

This rule, repeated frequently and as recently as 2007, has never been abrogated — impliedly or otherwise — as the dissent asserts.

Nor is analysis of a defendant’s duty “no different” from analysis of a plaintiffs negligence. It is true that when a hazard is obvious, the plaintiff will usually know about it. But that does not mean the plaintiff is negligent, as some like Ms. Parker must encounter a hazard because they have no other choice.32 By contrast, duty depends on a legal analysis balancing a number of factors, including the risk, foreseeability, and likelihood of injury, and the consequences of placing the burden on the defendant.33 Those factors are not necessarily the same for shoppers, deliverymen, or independent contractors who perform their own work with their own equipment in their own way. It was because of those factors that we adopted the rule limiting landowner liability to independent contractors in 1967; the dissent addresses none of them in urging that we change that duty today, instead simply pointing to Parker, a case that did not involve independent contractors at all. The distinctions drawn in the law may not always be easy, but we decline the dissent’s suggestion that we simplify them by mashing them all together.

When a defendant hires an independent contractor to come on premises and perform work as it sees fit, the defendant may reasonably expect the contractor to instruct its own employees on the safe means and manner of doing so. Regardless of whether Moritz acted prudently, the defendants had no duty to warn him that the ramp he used daily had no handrails. Accordingly, we reverse the court of appeals’ judgment and render a take-nothing judgment in favor of the defendants.
