Quick answer

A landlord may seek judicial ejectment when a tenant subleases in violation of the lease, uses the property for an unauthorized purpose that breaches the agreement, or uses it in a way inconsistent with the property’s nature and causes deterioration. For residential units covered by rent control, assigning the lease, subleasing any part of the unit, or accepting boarders or bedspacers without the owner’s written consent is expressly prohibited.

But unauthorized subleasing is not automatically established merely because another person is staying in the property. The lease terms, payment arrangement, control of the premises, length and purpose of the stay, and any written consent all matter. Outside the special rent-control rule, the Civil Code generally permits subletting if the lease contains no express prohibition, while assignment of the lease requires the lessor’s consent unless the contract says otherwise.

A landlord should document the breach, serve a legally adequate written demand to comply and vacate, complete barangay conciliation when required, and file an unlawful-detainer case in the proper first-level court within the applicable one-year period. A landlord should not forcibly remove occupants, change locks, cut utilities, seize belongings, or use threats in place of a court order.

First determine which rule applies

Residential units covered by rent control

The Rent Control Act prohibits assignment or subleasing of all or part of a covered residential unit—including accepting boarders or bedspacers—without the owner or lessor’s written consent. The same conduct is a statutory ground for judicial ejectment.

Current rental regulation under National Human Settlements Board Resolution No. 2024-01 runs through December 31, 2026. It covers qualifying residential units with monthly rent of ₱10,000 or less, subject to the resolution’s conditions. In 2026, the rent-increase ceiling for a qualifying unit occupied by the same continuing tenant is 1%. Coverage should be checked against the actual rent, occupancy history, type of unit, and current resolution.

The prohibition concerns subleasing without written consent. Oral permission, silence, or informal conversations can produce a factual dispute over consent, waiver, or acquiescence. Owners and tenants should put any permission, restrictions, duration, and approved occupants in writing.

Other leases governed principally by the Civil Code and contract

For leases outside that special rule, start with the written contract:

Under Article 1649 of the Civil Code, a tenant cannot assign the lease without the landlord’s consent unless the contract provides otherwise.
Under Article 1650, a tenant may generally sublet all or part of the property when the lease contains no express prohibition.
Even when subletting is permitted, the original tenant remains responsible to the landlord for performing the main lease.
Under Article 1651, the subtenant is bound to the landlord regarding acts involving the property’s use and preservation in the manner required by the main lease.
Article 1652 can make the subtenant subsidiarily liable for rent owed by the tenant, but only up to the rent the subtenant owed when the landlord made an extrajudicial demand.

Thus, a landlord cannot safely assume that every unapproved sublease violates a non-rent-controlled lease. If the agreement is silent, Article 1650 may permit it. The result can change if the arrangement is really an assignment, if another clause limits occupants or commercial activity, or if a statute, condominium rule, zoning rule, permit requirement, or lawful house regulation independently prohibits the use.

See Civil Code Articles 1649–1652.

What counts as prohibited use?

A tenant must use the property for the purpose stated in the lease. If no purpose is stated, the tenant must use it consistently with the property’s nature and local custom, exercising the care of a diligent person.

Common disputes include:

operating a store, office, warehouse, workshop, lodging business, or short-term accommodation in a residential-only unit;
accommodating paying boarders or bedspacers contrary to the lease or rent-control law;
conducting an activity prohibited by condominium rules, zoning classifications, building restrictions, or permits;
storing hazardous materials or carrying out alterations that threaten safety;
causing abnormal deterioration, overcrowding, repeated nuisance, or damage; and
allowing third parties to take control of the premises contrary to an occupancy clause.

Article 1673 allows judicial ejectment for violation of an agreed lease condition. It separately covers using the property for an unstipulated purpose that causes deterioration, or failing to observe the proper-use obligation under Article 1657.

The exact wording matters. A residential-use clause does not necessarily prohibit every work-from-home activity, visitor, caregiver, relative, or temporary guest. Evidence of payment, exclusive possession, advertising, room partitions, turnover of keys, repeated short-term occupants, business permits, deliveries, and the actual duration of stays may help distinguish a sublease or prohibited business from ordinary residential use.

Remedies available to the landlord

Demand compliance or correction

If the breach can be cured, the landlord may demand that the tenant:

stop the unauthorized use;
remove unauthorized commercial listings or advertisements;
end the sublease or boarding arrangement;
restore altered or damaged portions;
observe occupancy, safety, or condominium restrictions; and
comply within a definite, reasonable period stated in the demand.

Check the lease for any agreed notice-and-cure period. A landlord who ignores a contractual cure provision may weaken a later claim that the lease was validly terminated.

Terminate the lease and seek ejectment

Under Articles 1659 and 1673 of the Civil Code, breach of the tenant’s obligations or an agreed lease condition can support termination, damages, and judicial ejectment. The Supreme Court has recognized that a landlord need not always file a separate rescission case before seeking unlawful detainer; the demand and ejectment action may address termination and recovery of possession together. See Cetus Development, Inc. v. Court of Appeals.

An unlawful-detainer case generally requires proof that:

the tenant’s possession was initially lawful;
the right to possess later expired or was validly terminated;
the landlord demanded compliance with the lease and that the occupants vacate, when demand is required;
the tenant or occupants continued withholding possession; and
the complaint was filed within one year from the relevant unlawful withholding or last legally effective demand.

The allegations in the complaint—not merely its label—must establish these elements. If the one-year period has already elapsed, the appropriate remedy may be an ordinary action to recover possession rather than summary unlawful detainer.

Claim unpaid rent, reasonable compensation, and proven damages

A landlord may seek unpaid rent or reasonable compensation for continued use after termination. Proven repair costs and other foreseeable losses caused by the breach may also be claimed.

Damages are not automatic. The claimant must show the legal basis, causal connection, and amount through competent evidence such as contracts, receipts, photographs, inspection reports, invoices, testimony, or reliable market records. Attorney’s fees are recoverable only in circumstances allowed by law or by an enforceable contractual provision and remain subject to the court’s assessment.

Seek urgent protective relief when necessary

Immediate legal assistance may be needed if the use creates a fire, structural, environmental, public-health, or public-safety danger; involves violence or credible threats; causes continuing serious damage; or may destroy evidence.

The proper response may include notifying the building administrator or the appropriate fire, building, health, environmental, licensing, or law-enforcement authority. Reports should be truthful and supported by observable facts. Regulatory action does not automatically replace the need for a civil case to recover possession.

A legally careful enforcement process

1. Review every governing document

Collect and examine:

the signed lease and all renewals or amendments;
inventory, turnover, and condition reports;
written permissions or restrictions;
condominium declarations, master deeds, and house rules;
notices from the property manager or government authorities;
proof of ownership or authority to act for the owner; and
payment and deposit records.

Identify the precise clause breached. Do not rely only on a general belief that subleasing “must be illegal.”

2. Verify the facts without trespassing or harassment

Confirm who occupies the premises, how long they have stayed, whether they pay the tenant, and how the property is actually used. Use lawful sources such as publicly visible advertisements, communications voluntarily received, building records properly accessible to the owner, witness accounts, and authorized inspections.

A landlord’s right to inspect is controlled by the lease, law, privacy rights, and the tenant’s right to peaceful enjoyment. Ownership alone does not authorize an unannounced forced entry.

3. Preserve evidence properly

Keep original or complete copies of:

online listings showing the address, price, host, and dates;
messages admitting a sublease, boarding arrangement, or unauthorized business;
receipts, transfers, or acknowledgments of payments by occupants;
photographs and videos taken lawfully;
incident and security-log entries;
written complaints from neighbors or the condominium corporation;
permits, violation notices, or official inspection findings;
repair estimates and paid invoices; and
all notices, delivery receipts, acknowledgments, and returned mail.

For online evidence, preserve the full page, account name, URL, date, and surrounding context—not merely a cropped screenshot.

4. Send a clear written demand

For termination based on breach, the demand should ordinarily:

identify the lease and property;
state the specific acts and breached provisions;
demand compliance within the applicable cure period, if any;
state that the lease is being terminated when legally and contractually justified;
demand that the tenant and persons claiming under the tenant vacate and surrender possession;
demand payment or restoration where applicable; and
specify a deadline and delivery address.

Rule 70 generally requires a prior demand to pay or comply and to vacate when ejectment is based on breach of lease conditions. A notice that complains about the breach but never demands surrender may be inadequate.

Serve the notice through a method that produces reliable proof of delivery—such as personal service with acknowledgment, registered mail, an authorized courier, or another contractually valid method. Electronic service may supplement formal delivery, but whether it alone satisfies the law or contract depends on the documents and evidence.

5. Complete barangay conciliation when required

Katarungang Pambarangay proceedings may be a precondition when the parties are natural persons who actually reside in the same city or municipality and no statutory exception applies. The proper venue and exemptions depend on the parties, residences, urgency, nature of the dispute, and requested relief.

If applicable, obtain the proper certification to file action before going to court. Corporations and other juridical entities, disputes involving parties who do not meet the residence requirements, and matters falling under statutory exceptions require separate analysis. See Local Government Code, Sections 399–422 and the Supreme Court’s Katarungang Pambarangay guidelines.

6. File in the correct court on time

Unlawful detainer is filed in the Metropolitan Trial Court, Municipal Trial Court in Cities, Municipal Trial Court, or Municipal Circuit Trial Court with territorial jurisdiction over the property.

Ejectment cases are governed by the Rules on Expedited Procedures in the First Level Courts. The procedure uses short, strictly enforced periods. The defendant generally has 30 calendar days from service of summons to file an answer. Parties should not assume that ordinary civil-case extensions, motions, or delays are available.

The court may decide only the immediate right to physical possession in an ejectment case. Any ruling on ownership is provisional and only as necessary to resolve possession.

Rights and options of the tenant or alleged subtenant

A tenant receiving a demand should not ignore it. Promptly:

compare the accusations with the signed lease;
gather written consent, messages, receipts, and proof of the occupants’ relationship or purpose;
stop an ongoing curable breach if appropriate;
respond factually in writing without making unnecessary admissions;
continue paying undisputed rent through a traceable method; and
seek legal advice before surrendering possession, signing a waiver, or relying on an oral settlement.

Possible issues may include express written consent, a lease that does not prohibit subletting, waiver or acquiescence, failure to follow a cure period, defective or unserved demand, premature filing, incorrect barangay procedure, expiration of the one-year ejectment period, or failure to prove the alleged conduct.

A subtenant’s rights generally cannot exceed those of the principal tenant. If the principal lease is validly terminated, the subtenant may also be required to leave. However, removal must still occur through lawful process.

What landlords must not do

Even when the breach appears obvious, a landlord should not:

change the locks while occupants remain entitled to possession;
enter forcibly or remove doors;
disconnect water or electricity to compel departure;
confiscate, discard, or hold personal belongings;
threaten, intimidate, shame, or physically remove occupants; or
represent that an informal demand letter is already a court eviction order.

Articles 536 and 539 of the Civil Code prohibit acquiring possession through force when the current possessor objects and require recourse to the courts. Self-help measures can expose the landlord to civil liability and, depending on the acts committed, possible criminal or administrative consequences.

Common mistakes

Assuming all subleasing requires consent. Outside rent-controlled residential leases, Article 1650 may allow subletting when the contract contains no express prohibition.
Confusing a guest with a subtenant. Payment, control, duration, exclusivity, and the overall arrangement matter.
Treating assignment and sublease as identical. Assignment transfers the tenant’s leasehold position; subletting creates a subordinate arrangement while the original tenant remains responsible.
Sending a vague notice. The demand should identify the breach, require compliance when applicable, terminate on a valid basis, and demand surrender.
Accepting rent without documenting the legal effect. Continued acceptance after learning of the breach may generate arguments about waiver, acquiescence, or a continued tenancy.
Waiting too long. The one-year limit for summary ejectment can determine whether unlawful detainer remains available.
Filing before required barangay proceedings.
Using screenshots without preserving their source, date, URL, or context.
Claiming unproven repair costs or speculative lost income.
Removing occupants without a court order.

When legal help is urgent

Consult a Philippine lawyer promptly when:

the one-year ejectment deadline may be approaching;
the lease has conflicting termination, cure, or arbitration provisions;
the owner previously gave oral permission or repeatedly accepted the arrangement;
several occupants or businesses claim independent rights;
the tenant alleges illegal lockout, utility disconnection, harassment, or seizure of property;
there is serious damage, hazardous activity, violence, or a regulatory violation;
ownership, agency authority, succession, or the identity of the proper plaintiff is disputed;
barangay conciliation may or may not apply; or
summons, a complaint, a court order, or an appeal deadline has already been received.

Those unable to afford private counsel may inquire with the Public Attorney’s Office, subject to its legal and merit requirements.

FAQ

Can a landlord immediately evict a tenant for unauthorized subleasing?

No. The conduct may be a valid ground to terminate the lease and seek ejectment, but physical removal generally requires voluntary surrender or a court judgment implemented through lawful process.

Is subleasing always prohibited?

No. For covered residential units under the Rent Control Act, subleasing without the owner’s written consent is prohibited. For other leases, Civil Code Article 1650 generally permits subletting if the contract contains no express prohibition, subject to other lawful restrictions.

Is written consent necessary?

It is expressly required for subleasing covered by the Rent Control Act. In other cases, the contract determines whether consent is required. Written consent is strongly advisable because oral permission is difficult to prove and may not satisfy a statutory or contractual writing requirement.

Can relatives or friends stay without becoming subtenants?

Ordinarily, a genuine guest or family member is not automatically a subtenant. The conclusion depends on the lease’s occupancy restrictions and facts such as payment, duration, exclusive control, and whether rooms are being offered commercially.

Can a residential tenant run a business from the unit?

It depends on the lease, actual activity, property classification, condominium rules, and applicable permits. Quiet remote work is different from operating a shop, lodging business, warehouse, workshop, or customer-facing establishment. An unauthorized use that breaches the lease or causes deterioration may support ejectment.

Can the landlord sue the subtenant directly?

Persons claiming possession under the tenant may be included in an ejectment case when appropriate. Civil Code Articles 1651 and 1652 also recognize limited direct obligations of a subtenant to the landlord. Proper parties and claims should be assessed from the agreements and occupancy facts.

Does accepting rent after discovering the breach waive it?

Not automatically, but it may complicate the case. The result depends on the lease, communications, reservations made when accepting payment, and whether the landlord’s conduct objectively recognized continuation of the tenancy.

What if the tenant ignores the demand?

After completing any required barangay conciliation, the landlord may file the proper action within the applicable period. The landlord should preserve proof of service and avoid self-help eviction while the case is pending.
