2 GRIMM V. CITY OF PORTLAND
SUMMARY **
Fourteenth Amendment Due Process Clause/Vehicular
Tows
The panel affirmed the district court’s grant of summary
judgment for the City of Portland in an action brought by
Andrew Grimm alleging that the City’s procedures for
notifying him that his car would be towed were deficient
under the Fourteenth Amendment’s Due Process Clause.
Grimm parked a car on the side of a downtown street,
paid for an hour and 19 minutes of parking through a mobile
app, and then left the car on the street for seven days. During
that time, City parking enforcement officers issued multiple
parking citations, which they placed on the car’s windshield.
After the car sat on the street for five days, a parking
enforcement officer added a red slip warning that the car
would be towed. Grimm did not move the car, and, two days
after the warning slip was placed on the windshield, the car
was towed.
The panel held that the City conformed with the
requirements of the Fourteenth Amendment by providing
notice reasonably calculated to alert Grimm of the
impending tow. The warning slip placed on the car’s
windshield five days after Grimm had parked the car and two
days before the car was towed, which explicitly stated that
the car would be towed if it were not moved, was reasonably
calculated to inform Grimm of the impending tow.

The panel further held that Grimm’s failure to remove
the citations and warning slip from the windshield did not
provide the City with actual knowledge that its attempt to
provide notice had failed.

OPINION
H.A. THOMAS, Circuit Judge:
Andrew Grimm parked a car on the side of a downtown
street in the City of Portland, Oregon, paid for an hour and
19 minutes of parking through a mobile app, and then left
the car on the street for seven days. During that time, City
parking enforcement officers issued multiple parking
citations, which they placed on the car’s windshield. After
the car had sat on the street for five days, a parking
enforcement officer added to this growing pile a slip warning
that the car would be towed. Grimm did not move the car,
and, two days after the warning slip was placed on the
windshield, the car was towed.
4 GRIMM V. CITY OF PORTLAND
Grimm sued the City, alleging that its procedures for
notifying him that his car would be towed were deficient
under the Fourteenth Amendment’s Due Process Clause.
The district court granted summary judgment to the City.
The district court explained that, although Grimm’s failure
to remove the citations from the windshield might have
alerted the City that its attempt to provide notice had failed,
no other form of notice was practicable under the
circumstances.
We have jurisdiction under 28 U.S.C. § 1291. We hold
that the City conformed with the requirements of the
Fourteenth Amendment by providing notice reasonably
calculated to alert Grimm of the impending tow. We further
hold that Grimm’s failure to remove the citations and
warning slip from the windshield did not provide the City
with actual knowledge that its attempt to provide notice had
failed. We therefore affirm the district court’s grant of
summary judgment.
I.
A.
Like many municipalities, the City of Portland offers
people the option to electronically pay for parking through a
mobile app. In Portland, people may pay for parking using
Parking Kitty, an app created and operated by Passport
Parking, Inc. (“Passport”). Users of Parking Kitty must
provide a phone number to register with the app. To pay for
parking, users must input a credit card number and the
license plate number of the car they wish to park. Users can
also provide their email address to the app if they wish to
receive receipts by email. Parking Kitty sends users a
notification shortly before a parking session expires, and
another notification when the session has expired. Passport
GRIMM V. CITY OF PORTLAND 5
is a private entity, and the City cannot send notifications
regarding citations or towing through Parking Kitty. Nor
does Passport regularly share users’ contact information
with the City.
On October 25, 2017, Andrew Grimm registered as a
user of Parking Kitty. He entered into the app his phone
number, email address, credit card information, and the
California license plate number for a Honda Accord. Just
under two months later, on December 14, 2017, Grimm
parked the Accord on the side of a street in downtown
Portland. Using the Parking Kitty app, Grimm paid to use
the parking spot from 5:41 p.m. to 7:00 p.m. Grimm received
notifications from Parking Kitty when his parking session
was about to expire and when it expired. Grimm did not pay
to extend his parking time or initiate a new parking session.
Nor did he move the car.
At the time Grimm parked the car on December 14, the
vehicle registration for the Accord was up to date, but the
registration tags on the car were only valid through June
2017. 1 On December 15, a City parking enforcement officer
issued two citations and placed them on the car’s windshield:
one for being unlawfully parked in a meter zone without
proof of payment, and another for failing to display current
registration tags. On December 18, a parking enforcement
officer issued two more citations for the same offenses and
placed them on top of the December 15 citations.
On December 19, a parking enforcement officer issued
yet another citation for parking unlawfully and placed it on
top of the other citations. This time, the officer also placed
1
The registration for the car listed Grimm’s father, Fredrick, as the
registered owner and “Imperial ECU” as a lienholder.
6 GRIMM V. CITY OF PORTLAND
on the car a red slip warning that the car would be towed.
The warning slip displayed the word “WARNING” in large
print on one side and included on the other side the following
sentence: “Your vehicle will be subject to tow/citation if it is
not moved.” The officer circled the words “tow/citation” and
underlined the word “tow.”
On December 21, seven days after Grimm had parked
the car, a parking enforcement officer issued a final citation
for parking unlawfully and placed it on top of the other
citations. The cherry on top of this pile was another red slip,
this time displaying the word “TOW” in large print on one
side, and an order to tow the car on the other. After placing
the red tow slip, the officer contacted Retriever Towing,
which towed the car. The City then mailed a tow notice and
information about how to retrieve the car to the addresses
listed on the car’s registration. The City did not otherwise
attempt to contact Grimm.
Grimm did not return to the car before it was towed and
did not see the citations, the warning slip, or the tow slip. He
picked up the car from Retriever Towing on December 30,
paying $514 to do so.
B.
On January 26, 2018, Grimm filed a complaint in the
district court, alleging that the City, two parking
enforcement officers, and Retriever Towing violated his
rights under the Fourteenth Amendment’s Due Process
Clause. The district court granted Retriever Towing’s
motion to dismiss, and Grimm conceded that the parking
enforcement officers were entitled to qualified immunity,
leaving only the City as a defendant. The City then filed a
motion for summary judgment, which the district court
granted in July 2018. The district court applied the three-
GRIMM V. CITY OF PORTLAND 7
factor balancing test set forth in Mathews v. Eldridge, 424
U.S. 319 (1976), to hold that the City’s procedures for
notifying Grimm about the tow were reasonable.
In a 2020 decision, we reversed the district court’s
judgment, holding that the district court had applied the
wrong legal standard. Grimm v. City of Portland (Grimm I),
971 F.3d 1060, 1065–68 (9th Cir. 2020). We first determined
that “some individualized form of pre-towing notice was
required before Portland could tow Grimm’s car.” Id. at
1064. We explained that the case did not involve an
exigency, such as a car parked in the path of traffic, that
could justify towing the car without any advance notice. Id.
We then concluded that the district court had incorrectly
relied on the Mathews balancing test to determine the
adequacy of the City’s pre-tow notice. Id. at 1065. We held
that the appropriate test was that set forth in Mullane v.
Central Hanover Bank & Trust Co., 339 U.S. 306 (1950),
which requires “notice reasonably calculated, under all the
circumstances, to apprise interested parties of the pendency
of the action and afford them an opportunity to present their
objections.” Grimm I, 971 F.3d at 1065 (quoting Mullane,
339 U.S. at 314). We emphasized that the distinction
between these standards could be dispositive because, in
Jones v. Flowers, 547 U.S. 220 (2006), the Supreme Court
had explained that applying the Mullane standard sometimes
requires governments to undertake additional attempts at
notice when they become aware that their previous attempts
have failed. Grimm I, 971 F.3d at 1066.
We declined, however, to determine in the first instance
whether the City’s notice procedures were adequate under
the Mullane standard. Id. at 1068. We therefore remanded
8 GRIMM V. CITY OF PORTLAND
the case to the district court to consider, among other issues,
the following questions:
(1) Is putting citations on a car that do not
explicitly warn that the car will be towed
reasonably calculated to give notice of a tow
to the owner?; (2) Did the red tow slip placed
on Grimm’s car shortly before the tow
provide adequate notice?; and (3) Was
Portland required under Jones to provide
supplemental notice if it had reason to
suspect that the notice provided by leaving
citations and the tow slip on Grimm’s
windshield was ineffective?
Id. We did not expressly ask whether the warning slip placed
on Grimm’s windshield on December 19 provided adequate
notice because, at the time of that appeal, the record was
unclear as to whether such a slip had been issued. See id. at
1062 n.2.
On remand, the district court granted summary judgment
to the City. The district court determined that a citation
lacking an express warning of an impending tow would be
inadequate under Mullane. But the district court held that the
red warning slip, which was issued two days prior to the tow,
provided adequate notice because it expressly warned
Grimm that the car would be towed. The district court then
found that, although the City’s notice procedures were
constitutional, the City had information indicating that
Grimm did not receive notice because the City’s citations
and slips had piled up on Grimm’s windshield. The district
court thus held that, under Jones, the City was required to
provide additional notice to the extent practicable. But the
GRIMM V. CITY OF PORTLAND 9
district court determined that the City had no practicable
alternative means of providing notice to Grimm.
II.
“We review the district court’s grant of summary
judgment de novo, viewing the evidence and drawing all
reasonable inferences in the light most favorable to the non-
moving party.” Anthony v. Trax Int’l Corp., 955 F.3d 1123,
1127 (9th Cir. 2020) (quoting Cohen v. City of Culver City,
754 F.3d 690, 694 (9th Cir. 2014)). “We must determine
whether there are any genuine issues of material fact and
whether the district court correctly applied the relevant
substantive law.” Id. (quoting Cohen, 754 F.3d at 694). We
may affirm on any ground supported by the record. Zellmer
v. Meta Platforms, Inc., 104 F.4th 1117, 1122 (9th Cir.
2024).
III.
A.
We first consider whether the City provided notice
reasonably calculated to alert Grimm of the impending tow.
“An elementary and fundamental requirement of due process
in any proceeding which is to be accorded finality is notice
reasonably calculated, under all the circumstances, to
apprise interested parties of the pendency of the action and
afford them an opportunity to present their objections.”
Mullane, 339 U.S. at 314. In determining what notice is
appropriate under the Mullane standard, we must “balanc[e]
the ‘interest of the State’ and ‘the individual interest sought
to be protected by the Fourteenth Amendment.’” Tulsa Pro.
Collection Servs., Inc. v. Pope, 485 U.S. 478, 484 (1988)
(quoting Mullane, 339 U.S. at 314). A plaintiff need not
10 GRIMM V. CITY OF PORTLAND
receive “actual notice” under this standard. Dusenbery v.
United States, 534 U.S. 161, 170 (2002).
In Clement v. City of Glendale, we held that governments
must provide notice in most circumstances before towing an
illegally parked car. 518 F.3d 1090, 1095–96 (9th Cir. 2008).
We explained that “[t]he punishment for illegal parking is a
fine, which is normally imposed by affixing a ticket to the
windshield.” Id. at 1094. We emphasized that the “ticket can
also serve as notice of the illegality and a warning that the
car will be towed if not moved or properly registered.” Id.
We further explained that our holding was consistent with
our prior decision in Scofield v. City of Hillsborough, where
we “held that there was a due process requirement that notice
be given—usually in the form of a ticket placed on the
windshield—before police could tow apparently abandoned
vehicles that are otherwise legally parked.” Clement, 518
F.3d at 1096 (citing Scofield v. City of Hillsborough, 862
F.2d 759, 764 (9th Cir. 1988)).
Here, the City provided Grimm with all the notice that
the Fourteenth Amendment requires. The red warning slip
placed on the car’s windshield five days after Grimm had
parked the car was reasonably calculated to inform him that
the car would be towed. Id. at 1094–96. Although the
subsequent tow slip was placed on the windshield the same
day the car was towed, the warning slip provided two days’
advance notice that the car would be removed from the city
street. Cf. Grimm I, 971 F.3d at 1068 (describing the tow slip
as having been placed on the car “shortly before the tow”).
And, unlike the earlier citations placed on the car, the
warning slip explicitly stated that the car would be towed if
it were not moved. See id.
GRIMM V. CITY OF PORTLAND 11
Grimm cites the Supreme Court’s decision in Mennonite
Board of Missions v. Adams, 462 U.S. 791 (1983), for the
proposition that the warning slip placed on the car’s
windshield was inadequate. And, indeed, the Court held in
that case that “posted notices were inadequate to apprise a
property owner of condemnation proceedings when his
name and address were readily ascertainable from both deed
records and tax rolls.” Id. at 797 (citing Schroeder v. City of
New York, 371 U.S. 208, 210–11 (1962)). But Mennonite
Board of Missions is readily distinguishable. There, the
Court addressed the notice that a mortgagee must receive
before the forced sale of real property. See id. at 792–93. At
issue here is the notice that an individual must receive before
the temporary seizure of a car. Our precedents have already
made clear that a ticket placed on a car generally provides
adequate notice of an impending tow. Clement, 518 F.3d at
1094–96. And while it is undoubtedly the case that an
individual has an interest against being even temporarily
deprived of a vehicle, see Grimm I, 971 F.3d at 1063–64,
that interest is different than an individual’s interest against
the permanent loss of real property. Compare Mennonite Bd.
of Missions, 462 U.S. at 798, with Clement, 518 F.3d at 1094.
Second, this is not a case in which Grimm’s “name and
address were readily ascertainable” to the City. Mennonite
Bd. of Missions, 462 U.S. at 797. The Accord was not
registered to Grimm, but to his father, with a third-party
lienholder. And the City had no access to Grimm’s
information—or any ability to contact him—through the
Parking Kitty app.
But even if the car had been registered to Grimm, or if
the City could have obtained Grimm’s phone number or
email address through the Parking Kitty app, we reject the
notion that the City would have been required to track him
12 GRIMM V. CITY OF PORTLAND
down in this way before towing the car. A tow warning
slip—or a similar document or ticket expressly warning of
an impending tow—placed on a car two days before a tow
takes place is notice reasonably calculated to alert the user
of that car to an impending tow. An individual with an
interest in preserving uninterrupted access to his car would
revisit the car after his parking session ended or his meter
ran, and, seeing such a notice, would either move the vehicle
or pay for additional parking time. 2
A standard requiring the City to mail out a notice, send
an email, or make a phone call in addition to leaving a
warning slip would strike the wrong balance between the
“‘interest of the State’ and ‘the individual interest sought to
be protected by the Fourteenth Amendment.’” Tulsa Pro.
Collection Servs., Inc., 485 U.S. at 484 (quoting Mullane,
339 U.S. at 314). It is thus perhaps unsurprising that Grimm
cannot point to any cases requiring such action before a car
is towed. While Grimm cites the D.C. Circuit’s decision in
Propert v. District of Columbia, 948 F.2d 1327 (D.C. Cir.
1991), for the principle that notice by mail is required before
a government can tow a car with up-to-date registration,
Propert held no such thing. That case concerned the notice
required before a car is destroyed, not before it is towed. Id.
at 1328–30. The D.C. Circuit acknowledged in Propert that
a “warning sticker” that the government had attached to the
plaintiff’s windshield could “provide[] adequate pre-
towing—as opposed to pre-destruction—notice.” Id. at
1335. Although we would not in any event be bound by a
contrary decision from that court, Al Ramahi v. Holder, 725
2
Our holding here applies with equal force to a car that is illegally parked
in a location that does not require payment. See Clement, 518 F.3d at
1094–96.
GRIMM V. CITY OF PORTLAND 13
F.3d 1133, 1138 n.2 (9th Cir. 2013), Propert is thus
consistent with our holding here that the warning slip left by
the City provided Grimm with adequate notice.
B.
We next consider whether the City should have known
that its attempt at notice had failed because the citations and
slips remained undisturbed on Grimm’s vehicle before it was
towed. Grimm argues that this fact gave the City “good
reason to suspect” that its attempt to notify him had not been
received, and, citing to the Supreme Court’s decision in
Jones, urges that the City was therefore obligated to use
additional methods of notifying him.
Grimm overstates the Court’s holding in Jones. In that
case, the Supreme Court addressed whether the plaintiff
received adequate notice of an upcoming tax sale of his
home when a state government sent the plaintiff notice of the
sale through certified mail, but the mail was returned and
marked as unclaimed. Jones, 547 U.S. at 223–24. The Court
explained that, although notice by mail was generally
sufficient, it had “never addressed whether due process
entails further responsibility when the government becomes
aware . . . that its attempt at notice has failed.” Id. at 227.
The Court therefore characterized the question presented as
“whether such knowledge on the government’s part . . .
varies the ‘notice required.’” Id. (quoting Walker v. City of
Hutchinson, 352 U.S. 112, 115 (1956)). And the Court
ultimately held that the state’s use of certified mail was
inadequate because the state should have been aware that its
attempts at notice had failed when the mail was returned. Id.
at 229–34.
Viewing the evidence in the light most favorable to
Grimm, we cannot draw a reasonable inference that the City
14 GRIMM V. CITY OF PORTLAND
ever became aware that its attempt to notify him of the
impending tow had failed. Cf. id. at 227. While in Jones the
Supreme Court emphasized that “a feature of the State’s
chosen procedure is that it promptly provides additional
information to the government about the effectiveness of
notice,” id. at 231, nothing about the City’s method of notice
required Grimm to confirm that he had received it. 3 Grimm’s
argument also leaves little room for our prior holding in
Clement that notice provided by a ticket is generally
sufficient. 518 F.3d at 1094. Under the approach Grimm
advocates, individuals would need to regularly remove
citations from their vehicles to demonstrate that they had
received notice—and would have good incentive not to do
so if they wished to avoid being towed. But notice does not
become adequate only when its receipt is confirmed. See
Dusenbery, 534 U.S. at 171–72 (rejecting any requirement
that a prisoner sign for a piece of mail notifying him of his
right to contest the administrative forfeiture of his property).
Rather, absent specific information demonstrating that
notice was not received, the ultimate “failure of notice in a
specific case does not establish the inadequacy” of the
attempt. Jones, 547 U.S. at 231.
3
In Jones, the Supreme Court also explained that “when a letter is
returned by the post office, the sender will ordinarily attempt to resend it
. . . especially . . . when . . . the subject matter of the letter concerns such
an important and irreversible prospect as the loss of a house.” Id. at 230.
Here, as we have discussed above, the “subject matter” of the warnings,
although also important, did not concern a matter as “irreversible” as that
at issue in Jones. Id. It instead involved the temporary deprivation of a
car that had not been accessed, moved, or otherwise required by its user
for a week.
GRIMM V. CITY OF PORTLAND 15
IV.
While we do not dictate the precise form of notice that a
municipality must provide before towing a vehicle, such
notice must contain an express warning that the vehicle may
be towed. A citation that lacks an express tow warning
would not provide the notice that the Fourteenth Amendment
requires. Nor would a warning provided only shortly before
towing takes place be constitutionally adequate. 4
In the case before us today, Portland complied with these
requirements. By placing a warning slip on the windshield
of the Accord two days before the car was towed, the City
provided notice reasonably calculated to alert Grimm of the
impending tow. The fact that the citations and warning slip
remained on the car undisturbed did not provide the City
with actual knowledge that its attempt to notify Grimm had
failed. 5 The district court’s grant of summary judgment to
the City is therefore AFFIRMED.
4
Our decision today does not disturb the exceptions to the pre-towing
notice requirement that we recognized in Grimm I, Clement, and
Scofield. See Grimm I, 971 F.3d at 1064.
5
Because the City did not have actual knowledge that its attempt to
provide notice had failed, we do not reach the question whether any
additional forms of notice would have been practicable under the
circumstances.
