In short: England's overcrowding rules use a "room standard", which bars people of the opposite sex aged 10 or over, other than couples, from having to share a sleeping room, and a "space standard" based on the number and size of rooms, where living rooms can count. In practice, a one-bedroom flat usually suits one or two adults, possibly with a young child. HMOs have minimum bedroom sizes, such as 6.51 m² for one adult and 10.22 m² for two. Landlords can also limit occupants in the tenancy agreement.
