1What Portuguese Law Says About Subletting

Subletting (subarrendamento) in Portugal is governed by several provisions of the Civil Code and the NRAU. The fundamental rule is clear: a tenant may not sublet without the landlord's express written authorization.

Art. 1038º of the Civil Code lists the tenant's core obligations, which include not subletting or lending the property without consent. Art. 1049º reinforces this by making the landlord's written authorization a prerequisite for any lawful subletting.

This applies to: - Full subletting (tenant moves out and sublets the entire property) - Partial subletting (tenant remains but sublets a room or portion) - Short-term subletting (including Airbnb-style arrangements)

The prohibition is strict — even if the lease is silent on subletting, the default legal position is that subletting requires authorization.

2Authorized vs. Unauthorized Subletting

When subletting is authorized, the landlord gives written consent (ideally in the lease contract itself or via a separate written agreement). Key points for authorized subletting:

•The sublease cannot exceed the term of the main lease

•The sub-tenant's rent cannot exceed the main tenant's rent (in some cases)

•The main tenant remains responsible to the landlord for all lease obligations

•The authorization may be general ("tenant may sublet") or specific ("tenant may sublet to [named person]")

When subletting is unauthorized, the tenant has violated a fundamental lease obligation. Under Art. 1083º CC, unauthorized subletting constitutes grounds for the landlord to seek judicial termination (resolução) of the lease. This is one of the strongest grounds for eviction under Portuguese law.

Additionally, the landlord may claim damages for unauthorized subletting, including any profits the tenant earned from the illegal sublease.

3Short-Term Rentals and Airbnb

A common modern issue is tenants subletting on platforms like Airbnb without landlord consent. Portuguese courts have consistently held that:

•Short-term tourist rentals by a tenant constitute subletting

•These require the same landlord authorization as traditional subletting

•The property may also need a Alojamento Local (local accommodation) license

•Operating without both landlord consent and proper licensing creates dual legal liability

Landlords should address short-term subletting explicitly in the lease to avoid ambiguity. A clear prohibition in the contract makes enforcement straightforward if the tenant violates the restriction.

The Mais Habitação law also introduced additional restrictions on Alojamento Local licenses in certain areas, further complicating unauthorized tourist rentals by tenants.

4Common Mistakes to Avoid

For landlords:

•Not addressing subletting explicitly in the lease — while the law defaults to prohibition, a clear contractual clause prevents any argument about implied consent

•Failing to monitor the property — unauthorized subletting may go undetected for months, especially with short-term rentals

•Giving verbal consent without written documentation — verbal authorization is difficult to prove in court

For tenants:

•Assuming the landlord won't find out about unauthorized subletting — neighbors, utility bills, and online listings are common ways landlords discover it

•Subletting on Airbnb without understanding the legal consequences — this can result in lease termination, damages, and fines for unlicensed tourist accommodation

•Relying on informal agreements — "my landlord said it was fine" means nothing without written authorization

For both parties:

•Confusing subletting with having guests — a long-term guest who pays rent is effectively a sub-tenant, even without a formal sublease agreement

5How CompliantLease Handles Subletting Provisions

CompliantLease addresses subletting in the generated lease contract:

•Living rules clause — the contract includes a clear subletting provision, defaulting to prohibition unless the landlord specifically authorizes it

•Legal citations — Art. 1038º and Art. 1049º CC are referenced, ensuring both parties understand the legal basis

•Bilingual clarity — subletting restrictions appear in both Portuguese and English, preventing claims of misunderstanding by foreign tenants

•Consequence statement — the clause explicitly states that unauthorized subletting constitutes grounds for lease termination under Art. 1083º CC

This proactive approach ensures the subletting position is clear from the start of the tenancy, reducing the risk of disputes.

Frequently Asked Questions

Can a tenant sublet an apartment in Portugal?

Only with the landlord's express written authorization. Under Art. 1038º and Art. 1049º CC, subletting without consent is prohibited and constitutes grounds for lease termination under Art. 1083º CC.

What happens if a tenant sublets without permission in Portugal?

Unauthorized subletting is a fundamental breach of the lease. The landlord can seek judicial termination (eviction) under Art. 1083º CC and claim damages, including any profits the tenant earned from the unauthorized sublease.

Can a tenant rent out a room on Airbnb without landlord permission?

No. Short-term tourist rentals by a tenant constitute subletting and require landlord authorization. Additionally, the property needs an Alojamento Local license. Operating without both creates dual legal liability.

Does the lease need to mention subletting if it is already prohibited by law?

While the law defaults to prohibition, including an explicit clause prevents any argument about implied consent and makes enforcement straightforward. It also allows the landlord to set specific conditions if they wish to allow limited subletting.
