What Is a Bed and Breakfast?
A bed and breakfast (B&B) is a lodging business that offers short-term stays in a private home or in a small building converted for the purpose. The US industry code for B&B inns adds two defining traits: highly personalized service and a full breakfast included in the room rate (NAICS Code 721191 Bed-and-Breakfast Inns).

How a bed and breakfast works
B&Bs are typically located in private properties with live-in owners (What is a bed and breakfast? (Booking.com)).
State law can also define a B&B, and Wisconsin's statute shows what such a definition can include. A Wisconsin B&B rents 8 or fewer rooms to no more than 20 guests in total (Wisconsin Statutes s. 97.01 (1g)). It serves no meal other than breakfast, and serves breakfast only to the people renting rooms (Wisconsin Statutes s. 97.01 (1g)). Those limits apply in Wisconsin only, so an owner elsewhere checks the state and local rules where the property sits.
Federal accessibility rules draw a separate line. The ADA rules on public accommodations leave out lodging in a building with no more than five rooms for rent that the proprietor actually lives in (28 CFR 36.104 Definitions). That exclusion covers small owner-occupied lodging in general, B&Bs included, and whether a given property qualifies is a question for a lawyer.
Why it matters for hotel distribution
B&Bs are usually much smaller than hotels and have only a few rooms (What is a bed and breakfast? (Booking.com)).
That size changes the stakes of every booking. Even at Wisconsin's cap of 8 rooms, one room is an eighth of what the property can sell on a given night, so an unsold room or a double booking moves the night's results far more than it would at a 200-room hotel.
The segment is also hard to measure. It has long been overshadowed by the hotel industry and has lacked definitive market research to size it (The State of B&Bs in the U.S. (Phocuswright, Feb 2018)). For an owner, the property's own booking data is the most reliable guide to which channels earn their place.
Booking.com and Airbnb file B&Bs under their own property types, apart from hotels, as the comparison below shows. An owner selling on more than one channel describes the same property in each channel's categories, then keeps rooms, rates and availability matched across all of them.
Bed and breakfast compared with hotels, inns, vacation rentals and B&B rates
| Compared with | How it differs from a B&B |
|---|---|
| Hotel | Booking.com's connectivity codes list Hotel (code 20) as a hotel type and Bed and Breakfast (code 4) under Home properties (Property Class Type Codes, Booking.com Connectivity docs). |
| Inn | Inn (code 21) is also a hotel type in Booking.com's codes Property Class Type Codes, Booking.com Connectivity docs, even though the US industry code for B&Bs is titled "Bed-and-Breakfast Inns" (NAICS Code 721191 Bed-and-Breakfast Inns). |
| Guest house or homestay | Booking.com lists Guest House (code 40, OTA name "Pension") and Homestay (code 5004) as Home types of their own, separate from Bed and Breakfast (Property Class Type Codes, Booking.com Connectivity docs). |
| Vacation rental or Airbnb listing | Airbnb's listing types define a bed and breakfast as a hospitality business offering guests breakfast with a Host on-site, and keep it separate from the "Boutique hotel" type (How to define what kind of space you're hosting (Airbnb Resource Center)). |
| Bed-and-breakfast rate | A meal plan: OTA meal plan code 3, "Bed & breakfast", which Booking.com maps to its Breakfast plan (code 19) (Meal Plan Types, Booking.com Connectivity docs). |
