OPINION

GOULD, Circuit Judge:

Chris Kohler appeals from a grant of summary judgment to defendant Bed Bath & Beyond of California ("BB & B") on Kohler's claims under Title III of the Americans with Disabilities Act ("ADA"), and also appeals the award of attorneys' fees and costs to BB & B as a prevailing defendant. Regarding summary judgment, Kohler contends that the district court erred in concluding that the ADA does not require wall space within the maneuvering clearance next to the frame of a restroom door that must be pulled open; and that the district court erred in ruling that, BB & B, as a tenant, was not liable for ADA violations occurring in the parking lot outside of its store. Kohler further contends that the district court erred in concluding that several of his claims warranted the award of attorneys' fees to BB & B; and that the district court erred in its calculation of fees awarded. We have jurisdiction under 28 U.S.C. § 1291. We conclude that Kohler's substantive claims related to maneuvering clearance and tenant liability must be rejected and accordingly we affirm summary judgment. However, we agree that BB & B was not entitled to attorneys' fees for any of Kohler's claims, and so we reverse the district court's fee award.

Kohler is disabled; he is a paraplegic and requires the use of a wheelchair to move in public. Several times in May 2011, Kohler visited the BB & B store at the Lake Elsinore Marketplace in Lake Elsinore, California. During those visits he encountered purported architectural barriers, both within the store and in the parking lot of the shopping center, that he claimed impeded his ability to fully use the store. Kohler brought suit against BB & B in the U.S. District Court for the Central District of California. Kohler claimed violations of the ADA, 42 U.S.C. §§ 12101-12213, and related state law provisions. In his complaint, Kohler alleged ten purported access barriers; those relevant to this appeal relate to: (1) floor and wall space adjacent to the restroom door; (2) slopes and cross-slopes in the shopping center's parking lot; and (3) the placement and operation of toilet paper and paper towel dispensers within the BB & B's restroom.

The parties filed cross-motions for summary judgment. With respect to the claims of insufficient clearance next to the restroom door, the district court concluded that the ADA Accessibility Guidelines ("Guidelines"), which set out the ADA compliance requirements for physical structures, required only a minimum amount of floor space, rather than both floor and wall space on the pull side of a door. The district court also concluded that BB & B did not "own, lease or operate" the shopping center parking lot, and therefore was not liable for any ADA barriers occurring there. Finally, the district court concluded that Kohler had not asserted an actionable barrier with regard to the location of the toilet paper dispenser, as his complaint asserted only violations of state law, and that any violations related to the paper towel dispenser had been rendered moot when BB & B installed a new, compliant dispenser.1 On this basis, the district court denied Kohler's motion and granted BB & B's motion on all of Kohler's ADA claims. The district court declined to exercise supplemental jurisdiction over Kohler's state law claims and dismissed them without prejudice.

BB & B thereafter moved for attorneys' fees as the "prevailing party" under 42 U.S.C. § 12205. The district court concluded that eight of Kohler's ten claims "were, at a minimum, litigated without any foundation." Regarding Kohler's maneuvering space claims, the district court noted that it had described the claims as "illogical" in its summary judgment order, and that Kohler's counsel had unsuccessfully litigated similar claims. Regarding the parking lot claims, the district court held that Kohler should have been aware that BB & B did not own, lease or operate the parking lot for approximately the last year, as he had sued the shopping center's landlord and settled with it over the parking lot violations in September 2011. Regarding the toilet paper dispenser claim, the district court concluded that it was frivolous because it alleged a violation of a requirement not found in the ADA. Finally, the district court also concluded that Kohler's paper towel dispenser claim was "filed without any basis in law or fact," because Kohler alleged that operating the dispenser required "tight grasping, pinching or twisting of the wrist" but it was undisputed that he had full use of his hands. The district court made adjustments to BB & B's claimed lodestar, reduced that amount by twenty percent (to account for the proportional number of claims found frivolous), and awarded BB & B fees of $59,892.

Kohler timely appealed the district court's judgment, which is now before us.

We review a district court's grant of summary judgment de novo. Doran v. 7-Eleven, Inc., 524 F.3d 1034, 1047 (9th Cir.2008). We will uphold a summary judgment if "there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law." Fed.R.Civ.P. 56(a). We may affirm the district court on any basis supported by the record. Forest Guardians v. U.S. Forest Serv., 329 F.3d 1089, 1097 (9th Cir. 2003).

We review a grant of attorneys' fees for an abuse of discretion. Armstrong v. Davis, 318 F.3d 965, 970 (9th Cir.2003). However, "[a] court may abuse its discretion if it uses incorrect legal standards, which we review de novo." EEOC v. Bruno's Rest., 13 F.3d 285, 287 (9th Cir.1993)

III

Congress passed the ADA in 1990 "to provide clear, strong, consistent, enforceable standards addressing discrimination against individuals with disabilities." 42 U.S.C. § 12101(b)(2). Title III of the ADA prohibits discrimination in public accommodations, stating that "[n]o individual shall be discriminated against on the basis of disability in the full and equal enjoyment of the goods, services, facilities, privileges, advantages, or accommodations of any place of public accommodation by any person who owns, leases (or leases to), or operates a place of public accommodation." Molski v. M.J. Cable, Inc., 481 F.3d 724, 730 (9th Cir.2007) (quoting 42 U.S.C. § 12182(a)). Discrimination includes "a failure to remove architectural barriers... in existing facilities ... where such removal is readily achievable." Id. (quoting 42 U.S.C. § 12182(b)(2)(A)(iv)).

In appealing the summary judgment order, Kohler addresses only two sets of claims: those dealing with maneuvering clearance around the BB & B restroom doors, and those dealing with the slopes and cross-slopes in the shopping center parking lot.2

A

Kohler argues that the Guidelines require at least eighteen inches of clear wall length opposite the hinge side of a door that is pulled open. In Kohler v. Bed Bath & Beyond of California, LLC, No. 12-56727, we rejected the same claim; as a matter of law, the Guidelines do not require any length of wall space on the side of the doorframe opposite the hinges. 778 F.3d 827, 832-33 (9th Cir.2015). We affirm the grant of summary judgment to BB & B on this claim.

B

Kohler claims that the district court erred in determining that BB & B did not lease the parking lot at the shopping center, and that BB & B should have been obligated to remediate purported access barriers occurring in the parking lot. Further, he contends that BB & B's lease, which defined the parking lot as a "Common Area" and further stated that the "Landlord shall operate, maintain, repair and replace the Common Areas ... [and] shall comply with all applicable Legal Requirements," was an attempt to contract away its ADA liability in violation of our decision in Botosan v. Paul McNally Real., 216 F.3d 827 (9th Cir.2000). However, Kohler's reliance on that case is misplaced; our decision did not create liability for tenants, or landlords, where the ADA did not already impose it.

In Botosan, a landlord argued that it could not be held liable for ADA violations on leased property because all ADA compliance responsibility had been shifted to its tenants. See id. at 832. Examining the text and history of the ADA, as well as its implementing regulations, we concluded that the ADA imposes concurrent obligations on landlords and tenants, and that a landlord, as an owner of the property, should be liable for ADA compliance even on property leased to, and controlled by, a tenant. See id. at 832-34. The landlord could not contract away its responsibility under the ADA.

Here, Kohler seeks to extend Botosan to the inverse situation, to extend ADA liability for tenants to those areas of the property controlled by the landlord. But such an extension undermines the fundamental logic of Botosan. BB & B has no liability to contract away on parts of the parking lot over which it has no control. Absent a lease, a landlord remains in full control of an entire property, as its owner. The ADA imposes compliance obligations on "any person who owns, leases (or leases to), or operates a place of public accommodation." 42 U.S.C. § 12182(a). The existence of a lease that delegates control of parts of that property to a tenant has no effect on the landlord's preexisting obligation, because under the ADA, a party is prevented from doing anything "through contractual, licensing, or other arrangements" that it is prevented from doing "directly." 42 U.S.C. § 12182(b)(1)(A)(i). Here, in contrast, BB & B, like any tenant, has no preexisting control of a property. Absent a lease, it lacks any legal relationship at all to the property. That it takes control of a part of the property, subject to a lease, imposes ADA compliance obligations on it for that part of the property it controls; the landlord's preexisting obligations to the entire property continue unaffected. Botosan allowed a plaintiff to sue both landlord and tenant for ADA violations, confident that one party would be liable for barrier removal notwithstanding the lease provisions; this outcome served the goals of the ADA by "hamper[ing] efforts of a landlord and a tenant to evade ADA requirements." Botosan, 216 F.3d at 834. But Kohler's reading of our decision would impose upon a single tenant — e.g., the cell phone kiosk operating in a shopping center's lobby — liability for ADA violations occurring at the far end of the shopping center's parking lot; such an outcome serves no purpose other than to magnify the potential targets for an ADA lawsuit.3

Kohler points to the same two provisions of the ADA quoted above to support his argument, but neither is amenable to the construction he urges. To reiterate, § 12182(a) imposes compliance obligations on "any person who owns, leases (or leases to), or operates a place of public accommodation," while § 12182(b)(1)(A)(i) prohibits discrimination, either "directly, or through contractual, licensing, or other arrangements." 42 U.S.C. § 12182(a)-(b). However, there is no dispute that both landlords and tenants have compliance obligations under the ADA, and neither provision explains the scope of such an obligation, the crux of the matter here. As in Botosan, reference to the legislative history behind each provision suggests a particular construction of that scope. The history behind § 12182(a) explains that the provision

H.R.Rep. No. 101-485, pt. III, at 55-56 (1990) (Conf. Rep.). And the history behind § 12182(b) further explains that

Id., pt. II at 104 (emphasis added). Taken together, these conference reports from the legislative history highlight the implausibility of Kohler's urged construction of the ADA.

Our conclusion today is further supported by regulations, promulgated by the Department of Justice ("DOJ"), which implement the ADA. Specifically, § 36.403, which speaks to the scope of landlord and tenant obligations dealing with what is known as the "path of travel," implies that a tenant's obligations as to ADA compliance are limited to those parts of the property that it controls:

28 C.F.R. § 36.403. This reading is further supported by the DOJ's formal interpretation of the regulation in its Technical Assistance Manual, which includes the following scenario:

DOJ, Technical Assistance Manual on the Americans with Disabilities Act § III-6.2000 (1994) (emphasis added). "The [DOJ]'s interpretation of its own regulations, such as the Technical Assistance Manual, must also be given substantial deference and will be disregarded only if plainly erroneous or inconsistent with the regulation." Bay Area Addiction Research & Treatment, Inc. v. City of Antioch, 179 F.3d 725, 732 n. 11 (9th Cir.1999) (internal quotation marks omitted). Here, the DOJ's formal interpretation is entirely consistent with the regulation, and we give it the deference it is due.

We hold that neither the ADA, nor our decision in Botosan, imposes upon tenants liability for ADA violations that occur in those areas exclusively under the control of the landlord.5

IV

Finally, we reverse the district court's award to BB & B of attorneys' fees.

The ADA allows a "prevailing party" its fees. 42 U.S.C. § 12205. But while prevailing plaintiffs regularly recover their fees, "policy considerations which support the award of fees to a prevailing plaintiff are not present in the case of a prevailing defendant." Christiansburg Garment Co. v. EEOC, 434 U.S. 412, 418-19, 98 S.Ct. 694, 54 L.Ed.2d 648 (1978). Accordingly, "fees should be granted to a defendant in a civil rights action only upon a finding that the plaintiff's action was frivolous, unreasonable, or without foundation." Summers v. A. Teichert & Son, 127 F.3d 1150, 1154 (9th Cir.1997) (internal quotation marks omitted).

The district court erred in concluding that eight of Kohler's ten claims were frivolous. We have repeatedly cautioned that district courts should not "engage in post hoc reasoning," awarding fees simply "because a plaintiff did not ultimately prevail." Bruno's Rest., 13 F.3d at 290. This admonition applies even in cases which are resolved at summary judgment because no "reasonable jury could return a verdict in [the plaintiff's] favor." See Thomas v. Douglas, 877 F.2d 1428, 1434 & n. 8 (9th Cir.1989). Here, Kohler's claims regarding maneuvering space and the liability of a tenant for common areas were not clearly resolved by our prior caselaw interpreting the ADA. Kohler was entitled to bring this suit to seek resolution of these questions. See Gibson v. Office of Att'y Gen., State of Cal., 561 F.3d 920, 929 (9th Cir. 2009) ("Because Plaintiffs raised a question that was not answered clearly by our precedent, we hold that their claim was not frivolous."). The law grows with clarity for benefit of the public through such actions even if they are not successful.

We also reverse the district court regarding Kohler's paper towel dispenser claim, which was rendered moot by BB & B's voluntary remediation of the barrier. Though Kohler may indeed have litigated the claim without foundation, resolution of a claim via the mooting of any possible relief does not make BB & B a "prevailing party" entitled to fees, as there is no "judicially sanctioned change in the legal relationship of the parties." Buckhannon Bd. & Care Home, Inc. v. W. Va. Dep't of Health & Human Resources, 532 U.S. 598, 605, 121 S.Ct. 1835, 149 L.Ed.2d 855 (2001).

Kohler's final claim, related to the toilet paper dispenser, was also not frivolous. Kohler alleged that the dispenser was "difficult — if not impossible — for [him] to reach and use" due to its distance from the front of the toilet. The applicable Guideline does require dispensers to be "within reach," though it imposes no requirement that a dispenser be mounted a particular distance from the front of the toilet (only from the floor). 28 C.F.R. Pt. 36, App. D § 4.16.6. Kohler supported his claim by relying on a requirement found in California law, which the district court correctly concluded did not govern an ADA claim. But in this instance, Kohler's claim did not become frivolous simply because he referred to a state law requirement, and we reverse the district court's contrary conclusion.

V

The district court did not err in granting summary judgment to BB & B on Kohler's ADA claims and we affirm as to summary judgment. But the district court erred in determining that any of Kohler's claims were frivolous, and we reverse the award of attorneys' fees. Each party shall bear its own costs.

AFFIRMED in part and REVERSED in part.
