CIN and CIR in Milan and Lombardy: how to start a short let
On this page
Whether you have an apartment in Milan, a house on Lake Como or a chalet in Valtellina, renting to tourists in Lombardy follows the same pattern: a notice to the Comune (the town hall), then the regional code, then the CIN. Here's how it works, step by step.
Who it applies to
The procedure covers holiday homes and apartments (CAV) and homes, or parts of homes, let for tourist purposes, including short lets through Airbnb and Booking. Hotel-style services, or more than two apartments, count as a business and bring extra steps such as a SCIA (certified start-of-business notice).
Step by step
- Start-of-activity notice (CIA) to the Comune's SUAP. You file it online with the municipal business desk where the property is, usually through the impresainungiorno.gov.it portal.
- The Comune forwards it to the Province. For Milan and the surrounding area, it goes to the Metropolitan City of Milan.
- A record is created on ROSS1000. Once the notice arrives, the Province or Metropolitan City creates the property's record on the regional tourism-flows system ROSS1000 and contacts you with access details.
- Your CIR appears on Turismo5. You log in to the regional Turismo5 portal, where you find the property's regional code (CIR). The code is governed by Regional Council resolution XII/169 of 2023 and must appear in your listings as the law requires.
- CIN. With the CIR you log in to the Ministry of Tourism's accommodation database (BDSR) and get the CIN, after installing a fire extinguisher and gas/CO detector.
- Tourist-flow reporting on ROSS1000, by the regional deadlines.
- Alloggiati Web and tourist tax. Request police credentials from the Questura of your province. For tourist tax you register with the Comune; in Milan through the city's online services.
How long it takes
Step 3 is where patience is needed: you must wait for the Province or Metropolitan City to create the record and send you access. The Region sets no fixed deadline, so start well before your first booking.
Milan: guest identification
In Milan too, guests must genuinely be identified. Key boxes used without any check on the guest have been targeted by the authorities. Remote check-in is fine only if identity is really verified, for example by video call.
Frequently asked questions
I have a house on Lake Como. Is it the same as Milan?
Yes. Only the office that receives the notice from the Comune changes: the Province of Como instead of the Metropolitan City of Milan.
Can I file the SUAP notice without SPID?
Yes, through an intermediary acting under your delegation.
Are Lombardy's CIR and the CIN the same thing?
No. The CIR is regional and you need it to get the CIN, which is national. Both must be displayed.
