A large HMO is a shared house for seven or more people. In Plymouth, a place of roughly 260,000 people in Devon, the work is planned around the HMO rules for England and the council’s written HMO standards. Plymouth has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.

- Mandatory HMO licence for 5 or more people in 2 or more households (since October 2018); councils can add additional licensing for smaller HMOs.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.

- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
