What Are a Tenant’s Duties Under a Lease?
A tenant’s core obligations under a lease boil down to four things: pay rent, maintain the premises without committing waste, keep the property reasonably safe for invited third parties, and comply with the lease’s other covenants. Get these wrong on the exam — or in real life — and you’ll misjudge who owes what to whom.
Whether you’re prepping for the California Bar or you’re a tenant trying to understand your real exposure, these duties interact with landlord obligations, mortgage foreclosure, and even co-ownership in ways that aren’t obvious from a plain reading of a lease.
Tenant duties, defined in one sentence: a tenant must pay rent, avoid waste to the premises, keep the property reasonably safe for invitees, and comply with lease covenants, with liability for breach shaped heavily by California-specific statutes.
Duty to Pay Rent
If a tenant stops paying rent while still in possession, the landlord’s remedies are eviction or a lawsuit for unpaid rent — not self-help. California Civil Code § 789.3 flatly prohibits landlord self-help: no lockouts, no shutting off utilities. A landlord who violates this is liable for treble damages.
If instead the tenant abandons the property mid-lease, the calculus changes. Under Cal. Civ. Code § 1951.2, the landlord has an affirmative duty to mitigate damages by making reasonable efforts to re-let the unit. The landlord can then sue the departed tenant only for the deficiency — the gap between the original rent and what the replacement tenant pays. A landlord who lets the unit sit vacant for months without trying to re-let it will see that deficiency claim reduced or barred.
Duty to Repair: The Three Types of Waste
A tenant’s repair obligations track the same three categories used for a life estate:
- Affirmative (voluntary) waste — intentional destruction or removal of fixtures. A tenant generally cannot remove a fixture, even one the tenant installed, unless the trade-fixture exception applies.
- Permissive waste — failing to perform ordinary maintenance. Crucially, this liability is capped at the fair market rental value of the premises; a tenant can’t be on the hook for repairs that dwarf what they’re paying in rent.
- Ameliorative waste — unauthorized improvements. Even improvements that increase the property’s value can be prohibited at common law if unauthorized.
| Type of Waste | Conduct | Liability Cap |
|---|---|---|
| Affirmative (voluntary) | Intentional destruction/fixture removal | Full damages |
| Permissive | Failure to maintain | Capped at fair rental value |
| Ameliorative | Unauthorized improvement | Can be liable even if value increases |
Duty to Third Parties
A tenant remains liable to invitees injured on the premises, even where the lease shifts repair duties to the landlord. The tenant can seek indemnification from the landlord after the fact, but the tenant doesn’t get to point at the lease and walk away from a guest’s injury claim. This trips up a lot of students who assume a repair clause reallocates all liability.
Worked Example
Sofia leases a storefront from a landlord under a lease requiring her to “keep the premises in good repair.” Two years into the five-year term, the building’s aging roof develops a structural leak due to age and weather, not anything Sofia did. Sofia argues the landlord should pay for the repair since it’s not her fault.
Analysis: Because Sofia signed an express covenant to repair, she’s liable even for damage caused by ordinary wear, age, or the elements — this is treated close to strict liability at common law. If the damage is severe enough to be considered a substantial destruction of the premises, modern law may let Sofia terminate the lease instead of paying for the fix, but absent that, “good repair” language puts the cost on her, not the landlord.
How Recording and Ownership Changes Affect Tenant Duties
If a landlord sells the property, the buyer takes subject to a recorded lease and its terms, including repair obligations that run with the land. But a tenant’s personal covenants to the original landlord may not automatically bind or benefit a new owner absent privity or a covenant that runs with the land — a subtlety that matters when ownership changes mid-lease.
Mortgages complicate things further. If a landlord defaults and the property is foreclosed, a tenant generally must keep paying rent — to the original landlord or the new owner, depending on lease priority relative to the mortgage. A junior (subordinated) lease can be extinguished by foreclosure, but a tenant who keeps paying rent during the proceedings may have claims if wrongfully evicted afterward.
Common Mistakes to Avoid
- Assuming self-help eviction is legal in California. It isn’t — Civ. Code § 789.3 triggers treble damages for lockouts or utility shutoffs.
- Ignoring the landlord’s duty to mitigate. A landlord who sits on a vacant unit after abandonment can’t collect full rent damages.
- Treating permissive waste as strict liability. It’s capped at fair rental value, not open-ended.
- Applying the trade-fixture exception to residential tenants. It’s a commercial-tenant doctrine.
FAQ
Can a California landlord lock out a nonpaying tenant?
No. Self-help remedies like lockouts and utility shutoffs are prohibited under Cal. Civ. Code § 789.3, and a landlord who does this faces treble damages. The landlord must use the formal unlawful detainer (eviction) process.
What happens if a tenant abandons the unit mid-lease?
The landlord must make reasonable efforts to re-let the unit under Cal. Civ. Code § 1951.2. The former tenant is liable only for the deficiency between the original rent and what a replacement tenant pays, and that liability shrinks if the landlord fails to mitigate.
Is a tenant liable for damage from age or weather?
Under an express “good repair” covenant, generally yes — courts often treat this close to strict liability. Without such a covenant, ordinary permissive-waste rules apply, capped at fair rental value.
Key Takeaways
- A tenant’s core duties are paying rent, avoiding waste, protecting invitees, and following lease covenants.
- California prohibits landlord self-help eviction (Civ. Code § 789.3) and requires landlords to mitigate damages after abandonment (Civ. Code § 1951.2).
- Permissive waste liability is capped at fair rental value; affirmative and ameliorative waste are not.
- A tenant stays liable to invitees even if the lease shifts repair duties to the landlord.
- Trade fixtures are a narrow, commercial-tenant-only exception to the no-removal rule.
