Key figures and differences between the four categories
| Type | Rooms / beds | Practical difference |
|---|---|---|
| Bed & Breakfast | 3 rooms / 10 beds + 1 bed per room for a child under 12 | B&B in the household’s residence and domicile; it may be business or non-business. Limit: 3 rooms/10 beds, plus any extra bed for a minor. |
| Affittacamere / regional equivalent | DOMOS: 6 rooms; no single overall bed cap in the definition | The regional category that replaced Affittacamere is the “domo”: up to 6 rooms in one unit or in no more than two apartments within 100 metres; the activity must be registered with the Companies Register. |
| CAV / holiday apartments | No single regional cap on rooms/beds | CAV/apartment-based accommodation follows regional classification and IUN rules; capacity is the authorised capacity of the units, not one single regional cap. |
| Tourist rental | No single regional cap on rooms/beds | Tourist rentals are distinct from accommodation facilities: regional notifications, IUN/CIN, tourist flows and public-safety obligations apply as appropriate. |

Checks to carry out before you start
1. Identify the correct accommodation category
Before filing any application, determine whether the project is a B&B, an Affittacamere, a CAV or a simple tourist rental: permitted services, accommodation capacity, taxation and procedures differ.
2. Municipality and SUAP
Check whether a SCIA, CIA or other notification is required, together with tourist tax rules, any local regulations and the online procedures of the competent Municipality.
3. Property and accommodation capacity
Check permitted use where required, minimum room sizes, bathrooms, safety requirements, condominium rules and the number of beds that can actually be authorised.
4. Identification codes and guest-related obligations
Obtain the regional or provincial code where required and then the CIN; activate tourism-statistics reporting, Alloggiati Web and any other applicable obligations.
