These are Ministry of Tourism, Govt of India: Incredible India Bed and Breakfast guidelines.
Bed and Breakfast (BnB) owners have to go through an exhaustive process to register their homes as Silver or Gold category BnB. This process renders the accommodation safe for tourists and lets the tourists get a taste of real hospitality of India by staying in an Indian home with an Indian family.
