UBE Landlord-tenant
Last updated: May 2, 2026
Landlord-tenant questions are one of the highest-leverage areas to study for the UBE. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
A lease creates a nonfreehold estate giving the tenant a present possessory interest and the landlord a reversion. The four leasehold estates are the tenancy for years, the periodic tenancy, the tenancy at will, and the tenancy at sufferance, each with distinct termination rules. The landlord owes the tenant the implied covenant of quiet enjoyment in every lease and, in residential leases, the implied warranty of habitability; the tenant owes rent and a duty not to commit waste. Breach by either side triggers a defined menu of remedies — for the landlord, eviction and damages (subject to a duty to mitigate in most jurisdictions); for the tenant, termination, rent withholding or abatement, repair-and-deduct, or a constructive-eviction claim where the premises are rendered uninhabitable.
Elements breakdown
Tenancy for Years
A leasehold of fixed duration that ends automatically on the stated end date without notice.
- Fixed beginning and ending date
- Writing if term exceeds one year (Statute of Frauds)
- Terminates automatically at end of term
- No notice required to terminate
Periodic Tenancy
A leasehold that continues for successive identical periods until properly terminated by notice from either party.
- Successive equal periods (month-to-month, year-to-year)
- Created expressly, by implication, or by holdover
- Notice required to terminate equal to one period (max six months for year-to-year)
- Auto-renews absent timely notice
Tenancy at Will
A leasehold of no fixed duration terminable by either party at any time, though most jurisdictions now require reasonable notice.
- No stated duration
- Either party may terminate at will
- Reasonable notice typically required by statute
- Ends automatically on death of either party
Tenancy at Sufferance
A 'tenancy' arising when a tenant wrongfully holds over after lease expiration, lasting only until the landlord acts.
- Tenant in possession after lease ends
- No landlord consent to remain
- Landlord may evict or bind tenant to new periodic tenancy
- Tenant liable for reasonable rental value
Implied Covenant of Quiet Enjoyment
In every lease, the landlord covenants not to disturb the tenant's possession through wrongful conduct or paramount title.
- Tenant in lawful possession under valid lease
- Substantial interference by landlord or paramount title holder
- Interference attributable to landlord (act or failure to act on duty)
- Damages or constructive-eviction remedy available
Constructive Eviction
A tenant-side doctrine treating uninhabitable premises caused by landlord conduct as an eviction terminating rent obligations.
- Substantial interference by landlord (SING-style: Substantial, by landlord, Notice given, Goes out)
- Landlord notice and reasonable opportunity to cure
- Tenant vacates within a reasonable time
- Premises rendered substantially unsuitable for intended use
Implied Warranty of Habitability
In residential leases, the landlord warrants that the premises are fit for human habitation; this warranty is non-waivable in most jurisdictions.
- Residential lease (not commercial)
- Defect making premises unfit for basic human habitation
- Notice to landlord and reasonable time to cure
- Tenant remedies: terminate, withhold/abate rent, repair-and-deduct, or sue for damages
Common examples:
- No heat in winter
- No running water
- Severe vermin infestation
- Defective plumbing or electrical
Tenant's Duty to Pay Rent and Avoid Waste
The tenant must pay rent when due and refrain from voluntary, permissive, or ameliorative waste of the premises.
- Pay rent at time and amount specified
- Avoid voluntary waste (affirmative damage)
- Avoid permissive waste (failure to make ordinary repairs)
- Avoid ameliorative waste (substantial alteration even if increasing value)
Landlord's Remedies on Tenant Breach
On nonpayment or holdover, the landlord may pursue summary eviction and damages, subject to a duty to mitigate in most jurisdictions.
- Statutory eviction (unlawful detainer / summary process)
- Damages for unpaid rent and reletting costs
- Duty to mitigate by making reasonable efforts to relet (majority rule)
- No self-help eviction in most jurisdictions
Assignment vs. Sublease
An assignment transfers the tenant's entire remaining interest; a sublease transfers less than the entire interest, retaining a reversion.
- Assignment: transfer of entire remaining term
- Sublease: transfer of less than entire term (reversion retained)
- Assignee in privity of estate with landlord (liable on real covenants)
- Original tenant remains in privity of contract (liable on rent)
Common patterns and traps
The Constructive-Eviction Trap (Tenant Stayed Put)
The fact pattern describes terrible conditions — no heat, sewage backup, persistent noise from the landlord's other operations — and the tenant complains but never vacates. Constructive eviction is the doctrine that comes to mind, but it requires the tenant to actually move out within a reasonable time. The correct doctrine for a tenant who stays is the implied warranty of habitability (residential only) or breach of the covenant of quiet enjoyment (commercial or residential).
An answer choice says 'Yes, because the landlord constructively evicted the tenant' even though the vignette shows the tenant still living there at the time of suit.
The Commercial-Habitability Mistake
The implied warranty of habitability protects residential tenants only. A commercial tenant whose leased space is unfit cannot invoke habitability — the doctrine does not exist for commercial leases in the majority of jurisdictions. Commercial tenants are limited to the covenant of quiet enjoyment, constructive eviction, and whatever express warranties the lease provides.
A choice grants relief to a restaurant or office tenant 'because the landlord breached the implied warranty of habitability,' which sounds plausible but applies the wrong doctrine to a commercial lease.
The No-Mitigation Distractor (Minority-Rule Trap)
Under the majority/Restatement rule, a landlord whose tenant abandons must make reasonable efforts to relet — failure to mitigate caps the landlord's damages at the difference between the lease rent and what reasonable efforts would have produced. A few jurisdictions still apply the old common-law rule of no duty to mitigate, but the bar tests the majority rule. An answer that lets the landlord recover the full remaining rent without any mitigation effort is testing whether you know the modern majority rule.
A choice awards the landlord 'the full unpaid rent for the remainder of the term' with no reference to reletting efforts, when the facts show the landlord let the unit sit empty for months.
The Assignment-vs-Sublease Cut
If the tenant transfers the entire remaining term, it is an assignment; if anything less (even one day), it is a sublease. After assignment, the assignee is in privity of estate with the landlord and liable on rent covenants directly; the original tenant remains in privity of contract and is also liable unless expressly released (a novation). Sublessees are in privity with the original tenant only — the landlord cannot sue them directly for rent.
A choice says the landlord 'cannot recover from the original tenant after assignment,' missing that privity of contract survives transfer absent a release.
The Holdover-Tenancy Election
When a tenant remains after the lease ends, the landlord may either evict (treating the tenant as a tenant at sufferance) or hold the tenant to a new periodic tenancy on the prior terms. The election is the landlord's, not the tenant's. Many candidates mistakenly think the tenant chooses, or that the prior lease automatically renews.
A choice declares that 'the lease automatically renewed' upon holdover, ignoring that the landlord may instead evict and recover holdover damages.
How it works
Start every landlord-tenant question by classifying the leasehold — duration determines what notice is required to terminate. Then identify which side is alleging breach: if it's the tenant, ask whether the complaint is about possession (quiet enjoyment / constructive eviction) or about condition (warranty of habitability, residential only). Suppose Patel rents an apartment from Reyes Properties, LLC, on a month-to-month tenancy. The boiler fails in January; Patel notifies Reyes, waits two weeks, then withholds February rent. If Patel stayed in the apartment, constructive eviction fails (no 'going out'), but the implied warranty of habitability supports rent withholding because no heat in winter is a textbook habitability breach. If Reyes sues for unpaid rent, Patel's defense is the warranty — not constructive eviction — and Reyes must show either no defect, no notice, or a reasonable cure window honored. The framework is mechanical once you sort the doctrine to the facts.
Worked examples
What is Liu's strongest defense to Reyes's claim for unpaid rent?
- A Constructive eviction, because the lack of heat in winter substantially interfered with Liu's use of the premises.
- B Breach of the implied warranty of habitability, because the lack of heat rendered the apartment unfit for human habitation and Liu gave notice. ✓ Correct
- C Breach of the covenant of quiet enjoyment, because Reyes's failure to repair disturbed Liu's possession.
- D Frustration of purpose, because the cold weather destroyed the value of the leasehold to Liu.
Why B is correct: The implied warranty of habitability applies to residential leases and is breached when a defect renders the premises unfit for basic human habitation; lack of heat in winter is a textbook violation. Liu gave Reyes notice and a reasonable opportunity to cure, then exercised the rent-withholding remedy while remaining in possession — exactly what the warranty permits. Because Liu stayed, this is the correctly fitted doctrine.
Why each wrong choice fails:
- A: Constructive eviction requires the tenant to vacate within a reasonable time. Liu remained in the apartment, so the doctrine fails on its 'goes out' element regardless of how bad conditions were. (The Constructive-Eviction Trap (Tenant Stayed Put))
- C: Quiet enjoyment is breached by interference with possession (typically by landlord acts or paramount title), and while it overlaps with habitability, it does not by itself authorize rent withholding while the tenant remains; habitability is the precise doctrine for unfit residential conditions with the tenant in place.
- D: Frustration of purpose is a contract-formation-era doctrine that excuses performance when an unforeseen event destroys the principal purpose; cold weather in winter is not unforeseen, and the doctrine is not the residential-tenant remedy here.
From whom may Hwang recover the unpaid rent?
- A Only Okafor, because the assignment substituted Okafor for Patel as the tenant.
- B Only Patel, because the original tenant always remains primarily liable on the lease.
- C Both Patel and Okafor, because Patel remains in privity of contract and Okafor is in privity of estate. ✓ Correct
- D Neither, because Hwang accepted rent from Okafor and thereby novated the lease.
Why C is correct: Patel's transfer of the entire remaining term is an assignment. After assignment, the assignee (Okafor) is in privity of estate with the landlord and directly liable on the rent covenant; the original tenant (Patel) remains in privity of contract and is liable unless expressly released by a novation. Both are therefore liable, and Hwang may proceed against either.
Why each wrong choice fails:
- A: This forgets that privity of contract survives an assignment. Without an express release, Patel remains liable on the original lease promises even though Okafor is now in possession. (The Assignment-vs-Sublease Cut)
- B: Patel is liable, but not exclusively — Okafor is also liable through privity of estate as the current holder of the leasehold. Limiting recovery to Patel ignores the assignee's direct liability on real covenants like rent.
- D: Mere acceptance of rent from an assignee is not a novation. A novation requires the landlord's express agreement to release the original tenant and substitute the new one, which the facts do not show.
How much, if anything, may Nguyen recover from Brennan?
- A The full sixteen months of rent, because Brennan abandoned the lease and Nguyen had no obligation to find a replacement.
- B Nothing, because by accepting the keys Nguyen accepted Brennan's surrender and terminated the lease.
- C The shortfall between the lease rent and what Nguyen could have collected with reasonable reletting efforts, because the landlord must mitigate damages. ✓ Correct
- D Three months of rent only, because that is the maximum a landlord may recover after a tenant abandons under the Restatement.
Why C is correct: Under the majority/Restatement rule, a landlord whose tenant abandons must make reasonable efforts to mitigate by attempting to relet, and damages are capped at the difference between the lease rent and what reasonable efforts would have produced. The facts show Nguyen made no effort despite a strong market where comparable houses rented within weeks, so recovery is limited accordingly.
Why each wrong choice fails:
- A: This applies the old common-law minority rule that imposed no duty to mitigate. The bar tests the majority/Restatement rule, which requires reasonable reletting efforts and caps damages when the landlord sits on its hands. (The No-Mitigation Distractor (Minority-Rule Trap))
- B: Acceptance of keys alone is not an acceptance of surrender; the landlord may take possession to mitigate without releasing the tenant from the lease. Surrender requires a clear intent by both parties to terminate, which the facts do not show.
- D: There is no fixed three-month cap under the Restatement. Damages are measured by actual shortfall after reasonable mitigation, not by an arbitrary statutory ceiling.
Memory aid
For constructive eviction: 'SING' — Substantial interference, by landlord (Inaction or action), Notice and chance to cure, tenant Goes out (vacates). Miss the 'G' and the doctrine fails.
Key distinction
Constructive eviction vs. implied warranty of habitability: both respond to bad conditions, but constructive eviction requires the tenant to vacate within a reasonable time, while habitability lets the tenant stay and withhold/abate rent. Pick the wrong one and the remedy doesn't fit the facts.
Summary
Classify the leasehold, identify whose duty is breached, then match the remedy — staying tenants invoke habitability; vacating tenants invoke constructive eviction; landlords sue for rent and possession but must mitigate.
