Airbnb Rules Milan: 2026 Guide to Laws and Regulations

Milan Airbnb Compliance Checklist

• ☐ Obtain the CIR Code from Regione Lombardia

  • Register on the Regione Lombardia tourism portal and obtain your Codice Identificativo Regionale (CIR) before accepting any booking.

  • Confirm the registration category matches the property type: locazione turistica, B&B, or affittacamere.

• ☐ Verify Primary Residence Status If Applicable

  • Check whether the property qualifies as a primary residence under Milan's 90-day cap rules, or whether it falls under the non-primary-residence licensing tier with stricter limits.

• ☐ Confirm Condominium and HOA Approval

  • Review the condominium bylaws (regolamento condominiale) for any short-term rental prohibitions. A blanket ban by the condominium assembly is legally enforceable under Italian civil law.

• ☐ Register Guests with Polizia di Stato via Alloggiati Web

  • Submit each guest's identification data through the Alloggiati Web portal within 24 hours of check-in.

  • Retain copies of submitted records for a minimum of 5 years.

• ☐ Collect and Remit the Imposta di Soggiorno

  • Apply the applicable tourist tax per guest per night based on property category and star classification.

  • File returns and payments with Comune di Milano on the schedule set by the municipality, currently quarterly for most operators.

• ☐ Display the CIR Code on All Listings

  • Add the CIR code to every listing on every platform where the property is advertised. Platforms operating in Lombardy are required to display this code under Regional Law 27/2015.

• ☐ Install Required Safety Equipment

  • Fit operational smoke detectors in every sleeping area and hallway.

  • Install a CO detector where gas appliances are present, and confirm a fire extinguisher is accessible to guests.

• ☐ Verify TARI and Utility Classification

  • Confirm with Comune di Milano whether the property's waste tax (TARI) has been reclassified for commercial use, given STR activity. Misclassification is a common audit trigger.

• ☐ Configure the 90-Day Limit in Platform Settings

  • Set a booking calendar block

1. Regulatory Overview

Short-term rental activity in Milan operates under three distinct compliance layers: municipal rules set by the Comune di Milano, regional rules established by Regione Lombardia, and national legislation enacted by the Italian government.

All three apply simultaneously. A host who satisfies city requirements but ignores regional obligations is still non-compliant.

The primary governing instruments are Legislative Decree No. 79 of May 23, 2011 (the Tourism Code, which defines tourism accommodation categories at the national level) and Regione Lombardia Regional Law No. 27 of October 1, 2015, which classifies and regulates non-hotel accommodation, including private short-term rentals.

At the national level, Law No. 178 of December 30, 2020, introduced mandatory registration codes for all tourist accommodations across Italy, effective January 1, 2021.

Under Italian law, a short-term rental is defined as a residential lease of no more than 30 consecutive nights to the same guest. Rentals exceeding this threshold fall under standard tenancy law and exit the STR regulatory framework entirely.

Enforcement in Milan sits primarily with the Comune di Milano's Sportello Unico per le Attività Produttive (SUAP), which processes registrations and handles compliance for tourist accommodation.

Regione Lombardia's Direzione Generale Turismo, Marketing Territoriale e Moda retains oversight of regional classification standards and the Codice Identificativo Regionale (CIR) system.

2. Registration, Notification, and Airbnb License Requirements in Milan

Lombardy Regional Registry (cir Code)

Lombardy Regional Law No. 27 of December 2, 2019, established the mandatory regional tourism registry administered by the Regione Lombardia.

All hosts offering short-term rentals in Milan must register through the regional portal and obtain a Codice Identificativo Regionale (CIR) before accepting bookings. The registry became mandatory on January 1, 2021.

• Who Must Register: Any natural person or legal entity renting a residential property for periods under 30 consecutive days, including both primary and non-primary residences.

• Application Submission: Registration is completed through the Regione Lombardia online portal (SIRED system). No in-person filing is required.

• Required Documentation: Property title or lease authorization, host identity documents, and property address details. Condominium bylaw restrictions must not prohibit short-term rental use.

• Your assigned CIR code isn't a secret. It must appear in every single listing you have, from Airbnb and Vrbo to Booking.com. It's a non-negotiable requirement. This rule comes from Italy's national Decree-Law No. 50 of April 24, 2017, which forces platforms to ensure the 10-digit CIR code is visible and even handle tax withholding remittance. Bottom line: no code, no listing.

There is no primary-residence day threshold under Lombardy's framework. The 30-day rental duration ceiling is the operative boundary, not an annual night cap. Hosts renting the same property for a single period exceeding 30 days fall outside STR rules and into standard residential tenancy law.

National Suitup Registry

Italy's national short-term rental registry, established under Law No. 213 of December 30, 2023, introduced the Codice Identificativo Nazionale (CIN) mandatory from September 2, 2024. The CIN operates through the Ministry of Tourism's SUITUP platform and applies to all STR listings nationally, including Milan properties already holding a CIR code.

• Dual-Code Obligation: Milan hosts must display both the regional CIR and the national CIN on every listing and on physical signage at the property entrance.

• Safety Compliance Trigger: CIN registration requires hosts to certify that the property meets minimum safety standards, including a functioning carbon monoxide detector and

3. Building Rules, Condo Restrictions, and Neighborhood Limits

Don't go looking for Milan's version of NYC's Class A/B building rules, because you won't find one. It's a totally different system here.

The city doesn't maintain a master "prohibited buildings" list under national law or the Comune di Milano's local ordinances. Instead, whether your property, even a standard flat in a 1960s palazzo, is eligible for short-term rental activity depends on a messy overlap of three different private and public frameworks.

Condominium and HOA Bylaws

Under Articles 1135 and 1138 of the Italian Civil Code, condominium assemblies may vote to restrict or prohibit short-term rental activity within shared buildings.

A resolution passed by a majority representing at least 500 thousandths of the building's total ownership shares is legally binding on all unit owners, including those who voted against it.

Hosts must obtain and review the building's regolamento condominiale before listing. Violations can result in injunctions and civil damages claims from the condominium administrator.

• Regolamento Condominiale: The primary document governing permitted uses within a condominium building; supersedes platform terms on property eligibility.

• Assembly Resolutions: Post-purchase votes restricting STR activity are enforceable against all owners under Civil Code Article 1137.

Zoning and Urban Planning Constraints

Zoning dictates everything in Milan. The Comune di Milano's Piano di Governo del Territorio (PGT), freshly revised in 2023, is the document that matters most, as it carves the city into different land use zones.

If your property is in a strictly residential zone (zona residenziale pura) like the quiet streets of the Fiera district, you'll face much tougher scrutiny when applying for a CIR code under Lombardy Regional Law 27/2015.

And forget that farmhouse dream just outside the city; rural properties are almost always ineligible without a painful change-of-use approval. Good luck with that.

4. Operational Requirements and Restrictions

Host Presence

Milan does not impose a mandatory host-presence requirement under Lombardy Regional Law No. 27/2015 or the national short-term rental framework established by Law Decree No. 50/2017 (converted with modifications by Law No.

Hosts may rent without being physically present during guest stays. Remote management through a designated property manager or co-host is legally permissible, provided the SCIA (Segnalazione Certificata di Inizio Attività) filed with the Comune di Milano identifies a contact person reachable at all hours for emergencies.

Guest Limits and Occupancy

Occupancy ceilings are set by the habitability certificate (certificato di abitabilità) attached to each property, not by a citywide fixed number. The certificate specifies the maximum number of persons per unit based on floor area calculations under the Italian Ministerial Decree of July 5, 1975.

• Standard calculation: One person per 14 square meters of living space for the first occupant; one additional person per 10 square meters thereafter.

• Listing obligation: The declared maximum occupancy on any booking platform must not exceed the figure stated in the habitability certificate.

Exceeding the certified occupancy figure constitutes a violation reportable to the Comune di Milano's Sportello Unico Attività Produttive (SUAP).

Minimum-Stay Thresholds

No minimum-stay floor applies to non-professional hosts under national law. Stays under 30 consecutive days are classified as short-term rentals, subject to the cedolare secca flat tax regime.

Stays of 30 days or more fall outside the short-term rental classification and require a formal lease contract under the Codice Civile, Articles 1571–1614.

Note: A national bill currently under parliamentary review (DDL Concorrenza 2024, Senate Act AS-1698) proposes introducing a minimum two-night stay for STRs in high-density urban centers, including Milan. No effective date has been confirmed as of May 2026.

5. Taxes, Fees, and Reporting Obligations for Milan Hosts

City Tax (imposta Di Soggiorno)

Milan charges a tourist tax under Deliberazione del Consiglio Comunale n. 11/2012, subsequently revised by municipal resolution in January 2023.

The rate is €2.00 per person per night for standard short-term rental accommodations, capped at 10 consecutive nights per stay. Children under 12 are exempt. Hosts collect this tax directly from guests and remit it to the Comune di Milano quarterly.

National Tax Obligations

Total Combined Tax Rate: €2.00 per person/night (tourist tax) plus 21% cedolare secca on gross rental income, the minimum tax burden for a Milan STR host electing the flat-rate regime. Hosts outside that election face marginal IRPEF rates up to 43%.

Platform Collection Requirements

6. Safety, Habitability, and Guest Information Rules

Mandatory Safety Equipment

Milan enforces fire and safety standards through the Comando Provinciale dei Vigili del Fuoco di Milano (Milan Provincial Fire Command) under Decreto del Presidente della Repubblica n. 151 of August 1, 2011.

Short-term rental properties must maintain:

• Smoke Detectors: Operational detectors in every sleeping room and corridor, compliant with UNI EN 14604 standards.

• Carbon Monoxide Detectors: Required in any unit with gas appliances or non-electric heating systems.

• Fire Extinguisher: Minimum one 2kg ABC-rated extinguisher accessible per floor.

• Emergency Exit Signage: Illuminated exit indicators are required in multi-unit buildings with shared corridors.

Building Compliance

• Habitability Certificate (Certificato di Agibilità): Properties must hold a valid certificate issued by the Comune di Milano confirming structural and sanitary compliance.

• Electrical Safety: Wiring must meet Legge n. 46 of March 5, 1990 certification standards.

• Minimum Room Dimensions: Sleeping areas must meet the 9 m² per-person minimum under national sanitary housing regulations.

7. Booking Platform Requirements

Milan's short-term rental framework, established under National Decree-Law 50/2017 and reinforced by the Italian Revenue Agency's (Agenzia delle Entrate) subsequent implementation circulars, imposes direct obligations on booking platforms operating in Italy.

These are not voluntary compliance measures. Platforms that intermediate short-term rental transactions in Italy are legally required to act as withholding agents and data reporters.

Verification Requirements

• CIN Display: Platforms must verify that a valid Codice Identificativo Nazionale (CIN) is present on each listing before publication, per Article 13-ter of Decree-Law 145/2023, effective January 1, 2025.

• Listing Removal: Platforms are required to remove listings that lack a valid CIN upon notification from the Ministero del Turismo.

Reporting Requirements

• Tax Withholding: Platforms must withhold the 21% cedolare secca flat tax on rental income and remit it directly to the Agenzia delle Entrate on behalf of non-professional hosts.

• Annual Data Submission: Platforms must submit annual transaction reports covering host identity, property address, and gross rental income to the Agenzia delle Entrate. Non-compliant platforms face penalties up to €4,000 per violation under Article 4 of Decree-Law 50/2017.

Milan does not have a dedicated statute that prohibits the advertising of a short-term rental before a booking transaction occurs.

General consumer-protection rules under Italian national law apply to all commercial advertising, but those rules are not STR-specific and do not create a pre-transaction advertising prohibition of the kind that would trigger this section.

Property eligibility restrictions and registration requirements govern what hosts may legally operate, not what they may list or promote.

Hosts must ensure that any listing accurately reflects the property's registered status under the Codice Identificativo Nazionale (CIN) framework, but that is a disclosure obligation tied to the registration system, not an advertising ban.

8. How Enforcement Works and What Penalties Hosts Should Expect

Civil Penalties

Fines for non-compliance are not symbolic. They're real, and they sting. Milan's enforcement framework, established under Legge Regionale Lombarda.

27/2015 and the national Tourism Code (Decreto Legislativo n. 79/2011), carries significant financial penalties for violations, with fines often ranging from €500 to €5,000 per infraction. Don't test them.

• Operating without a valid CIR code: €500 to €5,000 per violation, applied per booking period under regional tourism law.

• Failure to display the CIR code in listings: €500 to €2,000 per listing, per platform where the omission appears.

• Non-payment or under-remittance of the tourist tax (imposta di soggiorno): Penalties equal to 100% of the unpaid amount, plus statutory interest under Decreto Legislativo n. 23/2011, Article 4.

• Failure to submit guest registry data to the Portale Alloggiati: €103 to €1,549 per unreported stay under Testo Unico delle Leggi di Pubblica Sicurezza (TULPS), Article 109.

Enforcement Mechanisms

• Platform data sharing: Airbnb transmits host and revenue data to the Agenzia delle Entrate under the 21% flat-tax withholding regime active since January 1, 2024.

• Complaint-driven inspections: The Comune di Milano's SUAP office and Polizia Locale respond to neighbor complaints, which have increased sharply in central districts since 2023.

• Proactive monitoring: Regional tourism authorities cross-reference Alloggiati Web submissions against active listings on major platforms.

• Tax audits: The Agenzia delle Entrate flags hosts whose declared rental income falls below platform-reported gross receipts.

Registration Denial and Revocation

The Comune di Milano can deny or revoke a CIR registration on the following grounds:

• False declarations in the SCIA or supporting documents.

9. Special Considerations

Rent-Controlled and Subsidized Units

Milan's rent-controlled housing stock, governed by the national framework under Law 431/1998 and regional Lombardy agreements, carries an absolute prohibition on short-term rental activity.

Lease contracts subject to canone concordato (agreed rent) explicitly forbid subletting in any form. A landlord who discovers STR activity in a rent-regulated unit may pursue immediate eviction under Article 1587 of the Italian Civil Code, and the tenant forfeits statutory rent protections accumulated over the tenancy.

• Subletting clauses: Standard concordato leases prohibit subletting without written landlord consent; STR activity constitutes unauthorized subletting regardless of duration.

• Social housing (edilizia residenziale pubblica): Any short-term rental in publicly assisted housing is prohibited outright and may trigger criminal referral to the Procura della Repubblica.

Condominium Properties

Milan's dense condominium stock is where most Airbnb regulation conflicts actually surface.

Under Legislative Decree 220/2004 and Article 1138 of the Civil Code, a condominium assembly may pass an STR prohibition with a majority representing at least 500 thousandths of the building's millesimal table. Once adopted, that rule is binding on all unit owners, including subsequent buyers.

• Regolamento condominiale: Contractual bylaws (adopted at founding) can restrict STR activity and bind owners even without an assembly vote.

• Noise and common-area rules: Guest violations of condominium rules expose the host to fines set by the building's administrator, separate from municipal penalties.

Historic and Protected Buildings

Properties listed under Legislative Decree 42/2004 (the Cultural Heritage Code) require prior authorization from the Soprintendenza Archeologia, Belle Arti e Paesaggio di Milano before any change of use, including frequent short-term rental activity.

Operating without that clearance risks fines starting at €1,549 per violation and potential criminal liability under Article 169 of the same decree.

10. Exemptions

Not all short-term accommodation activity in Milan falls under the municipal STR registration framework or the regional Lombardy licensing rules.

• Stays of 30 consecutive days or more: These qualify as medium-term residential tenancies under Italian Civil Code provisions and are governed by standard rental contract law, not short-term letting restrictions.

• Licensed hotels and hotel residences (residenze turistico-alberghiere): These operate under a separate commercial hospitality regime administered by Regione Lombardia and are not subject to the CIR code requirements applied to private STR hosts.

• Registered B&Bs with owner-presence: Where the owner resides on-site and rents no more than three rooms, a distinct regional classification applies with separate capacity and safety thresholds.

• Student housing and university accommodation: Purpose-built student residences operate under national education housing regulations, outside the scope of Airbnb rules Milan enforces on private listings.

11. Legislative Developments

Milan's short-term rental framework has been relatively stable since the Lombardy Region formalized its STR registration requirements under Regional Law No. 27 of 2015 and subsequent amendments through 2022.

No major municipal bills targeting Airbnb rules in Milan were pending at the time of the most recent review.

Regional Council Proposal (2023–2024 Review Cycle)

The Lombardy Regional Council initiated a review of its tourism accommodation framework in late 2023, examining potential amendments to the CIR (Codice Identificativo Regionale) assignment process. The review considered:

• Stricter owner-presence requirements: Proposed limits on non-resident operators holding multiple STR registrations.

• Faster CIR revocation: Reduced administrative timelines for suspending non-compliant listings.

• Platform data-sharing mandates: Requiring booking platforms to report occupancy data quarterly to the Regione Lombardia tourism office.

As of May 2026, none of these proposals has been enacted into binding law. Hosts should monitor the Regione Lombardia official portal for any formal legislative action.
