Quick answer

A landlord may require an unauthorized sublease or prohibited use to stop, terminate the lease when the contract or law permits, recover proven losses, and—if the occupants refuse to leave—seek judicial ejectment. The landlord generally cannot remove occupants by force, change the locks, cut utilities, seize belongings, or rely on threats.

The result depends first on the lease and the type of property:

For residential units covered by current rent-control regulation—generally units with monthly rent of ₱10,000 or less nationwide during 2026—subleasing any part of the unit, including accepting boarders or bedspacers, requires the owner’s written consent. Unauthorized subleasing is a statutory ground for judicial ejectment.
Outside that coverage, Article 1650 of the Civil Code generally allows subleasing if the lease contains no express prohibition. Assignment is different: a tenant generally cannot transfer the lease itself without the lessor’s consent unless the contract provides otherwise.
Using the property contrary to an agreed residential, commercial, or other permitted purpose may justify termination, ejectment, rescission, or damages, depending on the wording of the lease, the seriousness of the breach, and whether the use caused deterioration or violated law.

A landlord should document the breach, review the contract, serve a legally sufficient written demand, comply with barangay conciliation when required, and file the correct court action within the applicable period.

Is the arrangement really a sublease?

A sublease ordinarily exists when the tenant gives another person the right to occupy all or part of the property—usually in exchange for rent or another benefit—while the original lease remains in place.

Possible indicators include:

Listings on Airbnb, Facebook Marketplace, rental groups, or similar platforms;
Advertisements for rooms, beds, office desks, storage space, or short stays;
Regular payments by occupants to the tenant;
Occupants having keys and exclusive use of a room or area;
The tenant living elsewhere while another person controls the premises;
Written house rules, receipts, messages, or agreements between the tenant and occupant; and
Multiple boarders or bedspacers not disclosed to the owner.

The presence of relatives, household employees, caregivers, visitors, or a romantic partner is not automatically a sublease. Payment, duration, control of the premises, the tenant’s continued residence, and the lease’s occupancy provisions all matter. A clause limiting occupancy to named persons may be enforceable even when the arrangement does not technically qualify as a sublease.

An assignment is also different from a sublease. An assignment generally transfers the tenant’s leasehold position to another person, while a sublease creates a subordinate rental arrangement and leaves the original tenant responsible to the landlord.

When written consent is required

Rent-controlled residential units

Section 8 of the Rent Control Act of 2009 prohibits assignment or subleasing of all or any part of a covered residential unit—including accepting boarders or bedspacers—without the owner or lessor’s written consent. Section 9 expressly makes unauthorized assignment or subleasing a ground for judicial ejectment.

The National Human Settlements Board continued rent regulation for January 1, 2025 through December 31, 2026 under NHSB Resolution No. 2024-01. Its 2026 coverage applies to residential units with monthly rent of ₱10,000 or less nationwide.

Coverage is not determined by the label placed on the contract alone. The property’s actual use, monthly rent, location, and the statutory definition of a residential unit must be examined. Hotels, hotel rooms, motels, and motel rooms are excluded from the Act’s definition. Mixed-use premises may require closer review.

Other leases

For leases not governed by that special prohibition, Article 1650 of the Civil Code provides that a tenant may sublet all or part of the leased property when the contract contains no express prohibition. The tenant remains responsible to the landlord for performing the original lease.

This means that a landlord outside rent-control coverage should not assume that every unapproved sublease is unlawful. Check for provisions such as:

“No subletting” or “no assignment”;
A requirement for prior written consent;
Restrictions on boarders, transient occupants, short-term rentals, or sharing;
Limits on the number or identity of occupants;
A ban on transferring possession or allowing third-party use; and
Conditions governing corporate affiliates, employees, concessionaires, or licensees.

Consent given only orally may create a factual dispute, especially where the contract requires written consent. Messages, emails, payment records, the landlord’s knowledge, and prior dealings may become relevant. A landlord who knowingly accepted the arrangement for a long period may face arguments involving consent or waiver, although the effect depends on the contract and evidence.

What counts as prohibited use?

Article 1657 of the Civil Code requires a tenant to use the property diligently and devote it to the use stipulated in the lease. If the contract specifies no use, the permissible use may be inferred from the property’s nature and local custom.

Examples of potentially prohibited use include:

Operating a store, office, clinic, restaurant, warehouse, or manufacturing activity in a residential-only unit;
Using long-term residential premises primarily for transient accommodation;
Storing hazardous, flammable, illegal, or unusually heavy materials;
Conducting activities that violate zoning, fire-safety, sanitation, building, licensing, condominium, or subdivision rules;
Creating excessive noise, smoke, odors, traffic, structural loading, or security risks;
Making unauthorized structural alterations;
Housing more people than the lease or applicable safety rules permit; or
Using the premises for unlawful activity.

Not every technical or minor departure automatically warrants immediate termination. Courts may consider the contract’s wording, whether the provision is material, the harm or risk created, whether the tenant was given an opportunity to cure, and whether the landlord previously consented to or tolerated the use.

Under Article 1673, judicial ejectment may be sought for violating a lease condition or for devoting the property to an unstipulated use that causes deterioration or fails to meet the tenant’s duty of proper use. Articles 1659 and 1673 may also support rescission and proven damages, depending on the breach.

Separate government enforcement may be available when the activity violates zoning, fire, sanitation, business-permit, building, environmental, or criminal laws. A landlord should report only facts that can be supported and should not use an agency complaint merely to pressure a tenant in a private dispute.

Remedies available to the landlord

1. Require compliance

If the breach is curable, the landlord may demand that the tenant:

End the sublease or unauthorized occupancy;
Remove prohibited operations, equipment, stock, or alterations;
Apply for written consent or amend the lease;
Restore the property;
Observe occupancy, safety, or operating restrictions; and
Pay documented costs for damage attributable to the breach.

A negotiated solution should be written and signed. It should identify approved occupants or uses, the effective date, added conditions, responsibility for permits and damage, and whether the landlord is waiving any existing breach.

2. Terminate or rescind the lease

Termination may be available under an express contractual clause, the Rent Control Act, or the Civil Code. The notice should identify the exact contractual or statutory ground and comply with any contractual cure or notice period.

A lease clause authorizing extrajudicial cancellation may affect how termination is carried out, but it does not authorize forcible repossession. If the tenant disputes termination and refuses to surrender possession, the landlord should obtain possession through court proceedings.

Judicial rescission and damages may be sought for a sufficiently serious breach. Whether rescission is appropriate depends on the importance of the violated obligation and the available proof; trivial or incidental breaches may not justify ending the entire contract.

3. File an unlawful-detainer case

When possession began lawfully under a lease but became unlawful after valid expiration or termination, the usual summary remedy is unlawful detainer under Rule 70.

The landlord generally must first demand both:

Compliance with the lease condition, when compliance is still being required; and
Surrender of the property.

For a building, Rule 70 ordinarily requires the landlord to wait at least five days after the demand before commencing the case, unless the parties validly stipulated otherwise. The demand and the applicable contract should be reviewed together; granting a longer cure or surrender period means the landlord should observe that period.

The complaint is filed in the proper first-level court—Metropolitan Trial Court, Municipal Trial Court in Cities, Municipal Trial Court, or Municipal Circuit Trial Court—where the property is located. It may seek restitution of possession together with appropriate rent, reasonable compensation, damages, attorney’s fees, and costs when properly pleaded and proved.

An unlawful-detainer action generally must be filed within one year from the unlawful withholding of possession, commonly measured from the demand that validly terminated the right to remain. The starting point can be disputed, particularly where there were several demands, a fixed-term lease, prior termination, or long-standing tolerance. Repeated letters should not be assumed to restart an expired filing period.

If more than one year has passed, the appropriate remedy may instead be an ordinary action to recover the better right of possession, often called accion publiciana. That action follows different jurisdictional and procedural rules. Prompt legal advice is important before the one-year period becomes an issue.

Ejectment cases filed from April 11, 2022 are governed by the Supreme Court’s Rules on Expedited Procedures in the First Level Courts. A defendant generally has 30 calendar days from service of summons to file an answer. Evidence and required affidavits should be prepared early because the procedure restricts extensions, pleadings, and motions.

4. Claim damages or restoration costs

A landlord may claim losses caused by the tenant’s breach, including properly supported repair or restoration costs, unpaid contractual charges, and reasonable compensation for continued occupation. The original tenant may remain responsible even if the immediate damage was caused by household members, guests, visitors, or subtenants.

Recoverable amounts require proof. Preserve invoices, inspection reports, photographs, contractor estimates, receipts, payment records, and evidence connecting the loss to the breach. A penalty or liquidated-damages clause may be reduced by a court if it is unlawful, iniquitous, or unconscionable.

For a covered residential lease, the statutory deposit may be applied only to qualifying unpaid obligations or damage and only in an amount commensurate with the pecuniary loss. It should not automatically be treated as a forfeitable penalty.

5. Seek urgent protective relief

Immediate legal or government assistance may be appropriate where the use involves:

Fire, explosion, structural-collapse, or serious health risks;
Violence, threats, weapons, or danger to occupants or neighbors;
Suspected criminal activity supported by concrete facts;
Ongoing destruction or unauthorized construction;
Hazardous materials or serious environmental violations; or
A genuine risk that evidence or property will be removed.

Depending on the facts, counsel may consider an injunction or another provisional remedy. Emergency reports should be directed to the appropriate police, fire, building, health, or local government authority. The landlord should not personally confront dangerous occupants.

Barangay conciliation may be required

Under Sections 408–412 of the Local Government Code, prior proceedings under the Katarungang Pambarangay system are generally required when the dispute is between individuals who actually reside in the same city or municipality and the matter falls within the lupon’s authority. A real-property dispute is ordinarily brought in the barangay where the property or its larger portion is located.

Important exceptions include disputes involving parties who reside in different cities or municipalities, unless the relevant barangays adjoin and the parties agree; cases involving a juridical entity rather than two individual residents; and situations where direct court action is allowed, such as an action coupled with an appropriate provisional remedy or one that would otherwise be barred by limitations.

If barangay conciliation applies, obtain the proper Certificate to File Action before going to court. Parties ordinarily appear personally and without lawyers during the barangay proceedings. Filing at the barangay interrupts the prescriptive period, but the statutory interruption does not exceed 60 days, so do not let conciliation create a deadline problem.

What landlords should not do

Even a clear lease violation does not permit a landlord to take the law into their own hands. Article 536 of the Civil Code requires a person claiming the right to possession to seek the aid of the competent court when the occupant refuses to surrender it.

Avoid:

Changing locks while the tenant or occupants remain in possession;
Cutting electricity, water, internet, or other essential services to force departure;
Removing doors, windows, roofing, fixtures, or belongings;
Entering without consent except as lawfully allowed by the lease and genuine circumstances;
Threatening, harassing, publicly shaming, or physically removing occupants;
Seizing or disposing of personal property as “payment”;
Collecting rent directly from a suspected subtenant without legal advice; or
Accepting continued performance in a way that could undermine a claimed termination.

These actions can expose the landlord to civil, criminal, administrative, or possessory claims and may weaken an otherwise valid case.

Evidence to preserve

Keep original or reliable copies of:

The signed lease, renewals, addenda, house rules, and move-in inventory;
The title, tax declaration, authority to administer, or other proof of the right to possess;
Written consent requests and approvals or denials;
Demand letters and proof of delivery, receipt, posting, or personal service;
Messages, emails, advertisements, platform listings, receipts, and payment records;
Lawfully obtained photographs and videos showing actual use or occupancy;
Names of occupants and witnesses, without harassment or unlawful surveillance;
Security, visitor, access-card, and incident records maintained in the ordinary course;
Notices or findings from the barangay, condominium corporation, homeowners’ association, building official, fire authorities, or local government;
Inspection reports and before-and-after condition records;
Repair quotations, invoices, official receipts, and proof of payment; and
A dated chronology of discovery, notices, responses, inspections, and incidents.

Preserve electronic evidence in its original form when possible. Save the full message thread or webpage, date and time, account or URL, and surrounding context—not only cropped screenshots.

A practical step-by-step response

Confirm the facts. Distinguish a paying subtenant from a guest, relative, employee, caregiver, or permitted occupant.
Review every governing document. Check the lease, amendments, occupancy lists, condominium or subdivision rules, and any written consent.
Determine the applicable law. Confirm whether the premises are residential or commercial and whether current rent-control coverage applies.
Document lawfully. Use existing records, authorized inspections, public listings, and witness accounts. Do not trespass or invade private communications.
Assess safety and legality. Report genuine urgent hazards to the proper authority while preserving evidence.
Choose the desired outcome. Decide whether compliance, written approval, restoration, negotiated surrender, or termination is proportionate.
Serve a precise written notice. State the facts, violated provision, required cure, deadline, termination basis, demand to vacate, and reservation of rights. Keep proof of service.
Avoid inconsistent conduct. Before accepting rent or negotiating new terms after termination, ask counsel whether the action could be treated as consent, waiver, or a new lease.
Complete barangay conciliation if required. Secure the correct certificate and monitor the one-year ejectment period.
File the proper action promptly. Prepare the complaint, judicial affidavits, documents, and damages evidence under the current expedited rules.

Common mistakes

Assuming that all subleasing requires consent even when Article 1650’s default rule applies;
Relying on an oral “no subletting” instruction when the written contract says otherwise;
Treating every long-term guest or family member as a subtenant;
Sending a vague notice that demands payment or compliance but does not also demand surrender;
Naming only the original tenant while ignoring occupants whose possession must be addressed;
Waiting beyond the Rule 70 one-year period;
Skipping mandatory barangay conciliation;
Demanding speculative damages without receipts or causation evidence;
Entering or photographing private areas without lawful authority;
Accepting rent after termination without documenting its purpose; and
Using lockouts or utility disconnection instead of judicial process.

When legal help is urgent

Consult a Philippine lawyer promptly if:

The one-year unlawful-detainer period may be close;
The lease has already expired or several demands have been sent;
The tenant claims oral consent, waiver, renewal, ownership, or a right to remain;
The property is being used for short-term lodging, business, hazardous storage, or suspected unlawful activity;
There are unidentified occupants or several layers of subtenants;
A corporation, estate, co-ownership, agent, or foreign owner is involved;
The landlord wants an injunction or other provisional relief;
There has already been a lockout, utility interruption, entry, or removal of property;
The rent-control status is uncertain; or
The landlord has received summons.

The Public Attorney’s Office may assist qualified indigent parties, subject to its mandate, merit assessment, and conflict rules. Local Integrated Bar of the Philippines chapters may also provide information about legal-aid options.

Frequently asked questions

Can a landlord evict a tenant immediately after discovering an unauthorized sublease?

Usually not by physical removal. The landlord should establish the breach, issue the required notice or demand, comply with barangay conciliation when applicable, and obtain a court order if the occupants refuse to leave.

Is oral permission enough?

For rent-controlled residential units, the statute requires the owner’s written consent. For other leases, the answer depends on the contract and evidence. Oral permission may be disputed and may not satisfy a clause requiring prior written consent.

Can the landlord sue the subtenant directly?

The subtenant or other actual occupants may need to be included in a possession case, particularly if they claim a right through the tenant. Articles 1651 and 1652 of the Civil Code also impose limited direct obligations on a subtenant concerning use, preservation, and certain rent due. The correct parties depend on the documents and relief sought.

Is listing the unit online enough to prove subleasing?

A listing is useful evidence of an offer, but it may not prove that possession was actually transferred or payment received. Preserve the complete listing and corroborate it with occupancy, messages, access records, witnesses, or payment evidence.

Can a tenant run a small online business from a residential unit?

Possibly. Merely working online from home may differ from operating a customer-facing shop, warehouse, kitchen, clinic, or production facility. The lease, actual impact, zoning, permits, condominium or subdivision rules, and the property’s nature control.

Does accepting rent waive the violation?

Not automatically, but it may complicate the case. The effect depends on timing, knowledge, the lease, accompanying written reservations, and the parties’ conduct. Obtain advice before accepting post-termination payments.

Can a landlord keep the entire security deposit?

Not automatically. The landlord should account for lawful deductions and prove unpaid obligations or actual damage. Ordinary wear and tear is not the same as tenant-caused deterioration.

What if the lease has no subletting clause?

If the unit is covered by current residential rent control, written owner consent is still required. If it is not covered, Article 1650 generally permits subleasing when there is no express prohibition, although occupancy, use, safety, and assignment restrictions may still apply.

Can neighbors or a condominium corporation act separately?

Yes. Conduct may independently violate condominium rules, subdivision restrictions, nuisance rules, permits, or local ordinances. Those remedies do not automatically replace the landlord’s need to follow proper lease-termination and ejectment procedures.
