Is subletting legal in Italy, or does it depend?
It depends on one thing above everything else: which contract you signed. The baseline rule sits in Art. 1594 of the Codice Civile (the Civil Code), and it is surprisingly permissive: "Il conduttore, se non gli è vietato, ha facoltà di sublocare la cosa locatagli, ma non può cedere il contratto senza il consenso del locatore" — the tenant may sublet unless forbidden, but may never assign the lease itself without the landlord's consent, per the consolidated text on Brocardi.it.
Two Italian words matter here. Subaffitto (also sublocazione) means you stay the tenant and re-rent space to someone else. Cessione del contratto means you exit and someone replaces you on the original lease — that always needs the landlord's written agreement, no exceptions.
So "is subletting legal in Italy" has no yes/no answer. The law permits it by default; your specific contract almost certainly modifies that default. Read the contract before you promise a room to anybody.
What does Italian law say about subletting one room?

Residential leases get a stricter rule than the Civil Code baseline. Art. 2 of Legge 392/1978 — the equo canone law, still in force for ordinary residential subletting — splits the question in two, as published on Brocardi.it.
Subletting the whole apartment is prohibited unless the landlord agrees. Subletting part of it — one bedroom, say — is allowed salvo patto contrario, meaning unless your contract says otherwise. But the law attaches a procedural condition that almost nobody follows: you must notify the landlord in advance by lettera raccomandata (registered letter with proof of receipt), and that letter must state three things — the subtenant's identity, the duration of the sublease, and which rooms (vani) are involved.
Miss the letter and you have not "technically" complied. You have created a documented breach the landlord can use against you later. In practice a PEC (certified email) or a raccomandata A/R both give you the proof you want; a WhatsApp message does not.
Why do student and transitory contracts ban subletting anyway?

This is the part that catches Erasmus students. The Italian Ministry's official model contract for university students living away from home (contratto per studenti universitari, under Law 431/1998 and the Ministerial Decree of 30 December 2002) contains an explicit clause: beyond brief and occasional hospitality, the tenant may not give accommodation to anyone else, not even for free. La Legge Per Tutti quotes the ministerial facsimile and notes that breaking the clause is a contractual default the landlord can use to terminate the lease under Art. 1453 of the Civil Code.
The contratto transitorio (transitory-use lease, typically 1–18 months for a temporary need) carries the same restriction in its standard model. Between them, these two cover most foreign students in Italy.
Which contracts realistically leave room for a legal room-sublet? The free-market long lets: the classic 4+4 and the agreed-rent 3+2. If you signed one of those and the text does not forbid subletting, Art. 2 gives you a path. If you did not, assume the answer is no until the landlord writes otherwise. Not sure which you signed? Our breakdown of rental contract types in Italy shows how to tell them apart from the first page.
How do you sublet a room legally, step by step?
- Find the clause. Search your contract for sublocazione, subaffitto, ospitalità. If it bans subletting, stop here and go to the landlord instead.
- Notify in writing before anyone moves in. Registered letter or PEC, with the subtenant's full name, the sublease dates, and the specific rooms. That is exactly what Art. 2 of Legge 392/1978 asks for.
- Get consent in writing if the whole apartment is involved, or if the contract requires the landlord's approval at all. Verbal "sì, va bene" protects nobody.
- Write a real sublease contract. Names, codice fiscale (the Italian tax code, required for essentially every contract and payment here) of both parties, address, rooms, rent, dates, deposit, utilities split.
- Register it with the Agenzia delle Entrate within the deadline below, and pay rent by traceable transfer only.
Keep every document. If a dispute arrives six months later, the person with the paper trail wins.
Does a sublet contract have to be registered, and who pays tax on it?
Yes — a sublease is a rental contract, and the same registration rule applies. The Agenzia delle Entrate requires registration within 30 days of signing or of the start date, with one exception: contracts totalling 30 days or less per calendar year do not have to be registered. That exemption is why a two-week August sublet is administratively simple and a six-month one is not.
Tax is the piece most students never think about. If you sublet space for a maximum of 30 days at a time, the Agenzia delle Entrate's short-lets and cedolare secca guidance says the sublocatore (sub-landlord) can opt for the flat cedolare secca tax — 21% for a single unit, 26% otherwise — but must declare the income as redditi diversi (miscellaneous income), with no 5% deduction allowance. The original owner still declares their own rent separately.
Unregistered is not a grey area, it is a liability. According to SoloAffitti research reported by Skuola.net in October 2025, about 5% of reported student-rental cases involve undeclared rentals and unregistered contracts.
What money is actually at risk — deposit, rent, and scams?
The deposit first. Art. 11 of Legge 392/1978 caps the deposito cauzionale — what people colloquially call the caparra — at three months' rent, and it must earn legal interest paid to the tenant at the end of each year. A sub-landlord asking for five months upfront is outside the law, whoever they are. Photograph every room and every existing mark before you hand over cash, and get the amount written into the sublease.
Then the rent itself. According to Immobiliare.it Insights data reported by Sky TG24 in September 2025, the national average asking price for a single room in Italy was €613/month, up roughly 7–10% year-on-year: Milan €732, Bologna €632, Florence €606, Rome €575, against cheaper university cities like Chieti (~€228), Catanzaro (~€243) and Foggia (~€249). A second 2025 read — SoloAffitti data via Skuola.net — lands in the same order with different numbers (Milan €675, Rome €620, Turin €360, Florence €350, Bari €310), which is a useful reminder that a "market price" is a range, not a figure. If a sublet is priced far under it, that is a signal, not a bargain. We break the ranges down city by city in our Italy rental prices analysis for 2026.
Finally, fraud. That same SoloAffitti investigation reports online rental fraud up 20% over the previous two years, peaking at the start of each academic semester. PadovaOggi documented the classic pattern: two 20-year-old Erasmus students, one Spanish and one English, met a "landlord" in a Facebook housing group in August, paid a deposit to reserve the room, and the person vanished. Sublets are fertile ground for this because the seller can plausibly say "I can't show you the owner's contract."
What if your contract bans subletting and you still need to leave?
The honest options are better than the illegal one. Ask the landlord for a subentro — a replacement tenant who signs their own contract directly. Most landlords prefer this to an empty room, especially if you bring the candidate to them already vetted, with codice fiscale and proof of income or enrolment in hand.
If you are leaving mid-year, give notice in writing with the period your contract requires, and offer to help re-let. If you are the one looking for a sublet, ask three questions before paying anything: which contract type covers the apartment, has the landlord been notified in writing, and will you get a registered sublease in your own name. Anyone who dodges all three is selling you a problem.
For finding the replacement person, room-share platforms with real profiles beat anonymous Facebook groups precisely because the scam above starts with anonymity. Coinquilino (coinquilino.app), a free app for finding rooms and roommates in Italy, is one option — full disclosure: Coinquilino is our app — and our honest comparison of room-finding apps in Italy covers the alternatives, including the ones we do not run.
Can my landlord evict me for subletting without permission?
They can start proceedings, yes. Where the contract bans subletting — as the ministerial student model does — hosting someone else is a contractual default, and La Legge Per Tutti notes it is enforceable through Art. 1453 of the Civil Code, the provision on terminating a contract for breach. Outcomes depend on the judge and the facts, but you are defending, not attacking.
Can I sublet my room for a few weeks over the summer?
Legally the short duration helps with paperwork, not with permission. The Agenzia delle Entrate exempts contracts totalling 30 days or less per calendar year from registration, so a two-week sublet skips that step. It does not skip the contract clause or the registered-letter notice under Art. 2 of Legge 392/1978.
Does the subtenant need a codice fiscale and a permesso di soggiorno?
A codice fiscale, yes — you cannot register a contract, open utilities or pay properly without it. A non-EU subtenant will also hold a permesso di soggiorno (residence permit); an unregistered sublet gives them no housing document to show for the address, which can complicate permit renewals and residency (residenza) registration later.
Can I ask my subtenant for a deposit?
Yes, within the legal ceiling. Art. 11 of Legge 392/1978 caps the deposit at three months' rent and requires legal interest to be paid to the person who put it down, annually. Write the amount into the sublease and return it against a documented handover, not a memory of how the room looked.
Is a short Airbnb-style sublet the same thing?
Tax-wise it can be treated as a locazione breve: the Agenzia delle Entrate allows a sublocatore who re-lets for maximum 30 days at a time to opt into cedolare secca at 21% for a single unit or 26% otherwise, declared as redditi diversi. Legally it is still subletting, so the contract clause and the landlord notice still govern whether you may do it at all. Many municipalities add their own tourist-rental rules on top.
What is the safest single question to ask before signing a sublet?
"Can I see the head lease and the registered-letter notice sent to the owner?" A legitimate sub-landlord has both and shows them. That one request filters out most of the 20% rise in online rental fraud that SoloAffitti recorded, because a fabricated listing has no head lease to show.
