Appellant, Willie D. Young, appeals from an order of the trial court granting summary judgment to appellee, District of Columbia (District), on Young’s complaint for damages for wrongful eviction, negligence, and deprivation of constitutional rights under 42 U.S.C. § 1983. In his complaint, Young alleged that the District, acting through officers of the Metropolitan Police Department, assisted his sublessor in wrongfully evicting him from property in which he claimed to be a sublessee. Concluding that Young was “a mere occupant, arguably a trespasser, wrongfully in possession,” the trial court dismissed the wrongful eviction claim. The court dismissed the constitutional claim for lack of evidence to establish a protectable interest, and the negligence claim, for failure to designate an expert witness. Young argues for reversal, contending that the trial court erred in granting summary judgment because: (1) the District assisted his sublessor in wrongfully evicting him; (2) no expert witness is required to prove negligence because Young’s claim is that the District failed to provide any training for police enlisted to assist with evictions; and (3) evidence of the District’s past practice of assisting with evictions contrary to law formed an adequate basis for his constitutional claims. We hold that a material disputed issue of fact on Young’s wrongful eviction claim precludes summary judgment. Finding no error in the trial court’s ruling on the remaining claims, we affirm summary judgment with respect to those claims.
I.
A. Factual Background
For purposes of the summary judgment motion, except as otherwise indicated, the following facts were undisputed. William Bibbs leased an apartment at 1360 Peabody Street, N.W. from Washington Realty Company under the terms of a lease agreement which prohibited Bibbs from subletting or transferring possession of the premises in whole or in part. Several years later, Bibbs allowed Young to five in the apartment with Bibbs’ son. Bibbs did not occupy the apartment. In early April 1994, Bibbs notified his landlord that he would vacate the apartment on April 30, 1994. Although Bibbs informed Young of his plans, demanded his keys and said that he would no longer pay rent for the apartment, Young would not leave. 1 Young filed an application with the landlord to rent the apartment in his own name, but, according to his deposition testimony, his application was “squashed.” After Bibbs had vacated the apartment, the landlord contacted him and explained that he was responsible for getting all occupants out, or he would remain liable. Bibbs again explained this situation to Young and requested him to vacate, but Young still refused to leave. 2 Finally, on May 14th, Bibbs summoned the police for assistance. Police officers came to the building two times that day in connection with this mat *141 ter. 3 Initially, a police officer told Bibbs that he could not remove Young from the premises. Finally, an officer arrived who informed Young that Bibbs had said Young was a trespasser and wanted him to leave and turn over his keys. When Young inquired about the basis for the officer’s authority, the officer pointed to his shield. Young told the officer that he would not give him his keys, but would place them on the table. Young also took the keys from Bibbs’ son, who was apparently to leave also, and placed them next to his, and told the officer he would have to pick up the keys himself. 4 The officer picked up the keys and put both Young and Bibbs’ son out of the apartment. Bibbs’ version of these events differs from Young’s. Bibbs stated in a sworn response to an interrogatory that he had no conversation with Young on May 14, 1994, the day of Young’s ouster. It was Bibbs’ recollection that his wife spoke to Young that day and that “[s]he explained the situation to the police.” Four days later, Young secured a temporary restraining order requiring Bibbs to allow him to reenter the apartment; however, by the time Young returned, his possessions were no longer there.
The parties also dispute the circumstances surrounding Young’s occupancy. According to Bibbs, he allowed Young to stay in the apartment with his son temporarily, while he looked for a place to live because Young had no job and was homeless. Bibbs stated that he paid the rent and bought food for his son and for Young and that he did not charge Young rent. According to Bibbs, from time to time, Young offered small amounts of cash to help out with the food and rental expenses that Bibbs was paying, but they never had any agreement that Young would be a subtenant, and Young never paid rent. According to Young, the lease was in Bibbs’ name, and he sublet the premises to his son before Young moved in. In describing his agreement with Bibbs, Young stated in response to interrogatories that
When he [Young] moved into the premises in 1983, ... Bibbs was paying the rent for his son. My agreement with [Bibbs] was that I was to pay half the rent for the premises. I paid the rent ($200 a month) to ... Bibbs.
B. Trial Court’s Ruling
The trial court granted summary judgment for the District. The court concluded that Young was “a mere occupant, arguably a trespasser” and a stranger to the landlord. The court reasoned further that Young’s rights, if any, derived from Bibbs who had relinquished possession. Therefore, the actions of the police in ejecting Young were against someone wrongfully in possession. The trial court also concluded that the wrongful eviction claim must fail because such a claim will he only against a landlord, and the District was not a landlord and had no possessory interest in the property involved.
The trial court granted summary judgment for the District on the negligent training claim because Young did not designate an expert witness to establish the standard of care for training police officers assisting with evictions at the request of the person lawfully in possession. When the trial court granted summary judgment, the time for designating an expert witness had expired, and discovery was closed. The court also rejected Young’s § 1983 claim because: (1) Young’s right to remain in the property was not a federally protected right; and (2) in opposition to the motion for summary judgment, Young had failed to show a pattern of police conduct, “from which a de facto government policy to violate the statutory right of tenants may be inferred.” For similar reasons, *142 the trial court granted summary judgment for the District on Young’s remaining constitutional claims. The court also concluded that the District could not be held liable under a respondeat superior theory for Young’s remaining constitutional claims.

Young argues on appeal that the trial court erred in concluding that he was not lawfully in possession as Bibbs’ subtenant. Therefore, he contends, Bibbs could not evict him without court process, and the District is jointly and severally liable with Bibbs for assisting in his wrongful eviction. It is well settled in this jurisdiction that a landlord may not use self-help to evict a tenant and that “the legislatively created remedies for reacquiring possession [of real property] are exclusive.”
Mendes v. Johnson,
Where a tenant subleases property, the tenant has a responsibility to see that the subtenant vacates the premises in order to surrender them to the landlord without further liability.
See Sanchez v. Eleven Fourteen, Inc.,
It is undisputed that Bibbs and Young had no written agreement establishing a subtenancy. However, certain tenancies may arise by oral agreement of the parties. Where real property is rented by the month without a written agreement, by statute, the estate created “shall be deemed [an] estate[] at sufferance.” See D.C.Code § 45-220;
see also Comedy, supra,
*143
The question is whether the undisputed facts showed that Young was not a tenant, as the trial court concluded. “A landlord-tenant relationship does not arise by mere occupancy of the premises; absent an express or implied contractual agreement, with both privity of estate and privity of contract, the occupier is in adverse possession as a ‘squatter.’ ”
Nicholas v. Howard,
The District argues that even if Young’s evidence is credited, he could be no more than a paying guest or a roomer who is not a tenant within the meaning of the law governing landlord-tenant relationships. It contends that a paying resident in a rooming house cannot be a tenant within the meaning of the law governing landlord-tenant relationships. 12 The District contends that Young’s evidence shows that he had only an informal agreement with Bibbs to pay half the rent so long as Bibbs allowed him to stay in the apartment. Therefore, when Bibbs asked Young to leave, and Young refused, he became a trespasser.
The critical distinction between a tenant and a roomer is that “[a] tenant is a purchaser of an estate, entitled to exclusive legal possession, but a roomer has merely a right to use the premises.”
Beall v. Everson,
The factual dispute concerning whether a landlord-tenant relationship existed between Bibbs and Young is a material fact essential to a determination of whether Bibbs wrongfully evicted Young with the assistance of the District’s police officers.
15
Where there is a genuine issue of material fact in dispute, summary judgment cannot be granted.

See Drejza v. Vaccaro,
III.
Young argues that the trial court erred in dismissing his claims for negligent training and supervision, deprivation of constitutional rights under 42 U.S.C. § 1983, and other constitutional claims for failure to name an expert witness. He contends that no expert is required because the alleged negligent conduct is within the reahn of common knowledge and everyday experience.
See District of Columbia v. Hampton,
In a negligence case, the plaintiff has the burden of establishing “‘the applicable standard of care, a deviation from that standard by the defendant, and a causal relationship between the deviation and the plaintiffs injury.’ ”
District of Columbia v. Hampton, supra,
IV.
Finally, Young contends that he showed an adequate basis to prevail on his § 1983 claim. Specifically, he relies upon facts purporting to show that the police engaged in a series of unconstitutional acts which support an inference that such acts were pursuant to a
de facto
policy.
See Gomez v. City of West Chicago,
Assuming that the police assisted Bibbs in wrongfully evicting Young, an issue which remains for determination, Young failed to show evidence supporting the § 1983 claim, as the trial court concluded. “Local governing bodies ... can be sued directly under § 1983 for monetary, declaratory, or injunctive relief where ... the action that is alleged to be unconstitutional implements or executes a policy statement, ordinance, regulation, or decision officially adopted and promulgated by that body’s officers.”
Monell v. Dep’t of Social Servs. of City of New York,
For the foregoing reasons, summary judgment hereby is reversed on Young’s wrongful eviction claim, and affirmed on the remaining claims.
So ordered.
Notes
. According to Young, Bibbs did not inform him that he was giving up the apartment until early May 1994.
. Young explained at deposition that the reason that he did not leave was
[b]ecause I had made preparation to obtain an apartment myself, and plus I felt that he had no authority to even ask me to leave because I was making preparations to move in myself and he had gave up any right, any authority for the apartment.
. Police officers came one other time at Young’s request on an unrelated matter concerning a dispute he had with a friend of a tenant on the second floor of the building.
. Bibbs' son told Young that the police were going to put them both out before Young went in to converse with the last officer who came.
. The definitions of a tenancy at sufferance in D.C.Code § 45-820 is the same in material respects to the definition in D.C.Code § 45-220.
. There may be a contractual prohibition to subletting, as there was here. However, "restrictions contained in the original lease against subletting do not affect, as between *143 the lessee and the sublessee, the validity of the sublease." 49 Am. Jur.2d Landlord and Tenant § 1162 (1993). See also Freedman on Leases § 7304d (4th ed. 1997).

Anderson, supra,
the issue under consideration was whether two men who occupied an apartment in partial compensation for performing services in the building were tenants.
Anderson,
. For disposition of this appeal, we need not address the rights of Bibbs’ landlord as against any subtenant.
See Sanchez, supra
. "This court has 'ruled on several occasions that rent control statutes [such as the 1985 [Housing] Act] prevail over provisions adopted earlier that govern evictions, to the extent that the provisions conflict.’ ”
Anderson, supra,
. D.C.Code § 45-2503(15) and (36) provide respectively that:
"Housing provider” means a landlord, an owner, lessor, sublessor, assignee, or their agent, or any other person receiving or entitled to receive rents or benefits for the use or occupancy of any rental unit within a housing accommodation within the District. “Tenant” includes a tenant, subtenant, lessee, sublessee, or other person entitled to the possession, occupancy, or the benefits of any rental unit owned by another person.
.A "rental unit” is defined in the Housing Act, in pertinent part, to mean:
any part of a housing accommodation as defined in paragraph (14) of this section which is rented or offered for rent for residential occupancy and includes any apartment, efficiency apartment, ... suite of rooms, or duplex.
D.C.Code § 45-2503(33). D.C.Code § 45-2503(14) referenced in subsection (33) describes a "housing accommodation,” in relevant part, as "any structure or building in the District containing 1 or more rentals units
.The District did not argue in the trial court that Young was a roomer. Therefore, the trial court did not consider whether Young was a roomer and whether the rights accorded tenants under the Housing Act extend equally to roomers. We do not, and need not resolve whether individuals who rent a single room within a person’s home or a rental unit are tenants within the meaning of the Act. See D.C.Code §§ 45-2503(14), (15), (33) and (36) and notes 10 and 11,

.The prior tenant formerly owned the property, but apparently remained in possession after foreclosure under a deed of trust, by reason of which the former owner and those in possession claiming under him are construed by statute as tenants at will. D.C.Code § 45-222;
Thompson v. Mazo,
. On the day that the police came, Bibbs’ son came outside and met Young. According to Young, he was "upset and crying,” and he told Young that "the police are going to put us out.”
. The District argued in the trial court that, even assuming that Young was Bibbs’ tenant, the District could not be held responsible for a wrongful eviction because "[Young] had no privity of estate or privity of contract with the John Doe Police Officer or the District of Columbia.” It contended that a claim for wrongful eviction could be maintained only against those having a possessory or ownership interest in the property, and therefore the claim could not be prosecuted against the District. Young argues on appeal that the District is a joint tortfeasor.
See Knell v. Feltman,
.According to Young’s deposition testimony, when the police came to the apartment and requested him to leave, he did not protest that he was a lawful tenant or otherwise explain that he had the right to be there. The District did not argue in the trial court that it was undisputed that the police had no reason to know that Young was anything other than a trespasser, and therefore, cannot be held in tort for acting on the basis of the knowledge available at that time. Thus, the District did not treat this as a "material fact” relevant to its summary judgment motion, and calling for a response by Young. In such a posture, we do not address this issue on appeal.
