A house to HMO conversion turns a single-family home into a house in multiple occupation: a shared home for unrelated people with private bedrooms and shared kitchen or bathroom space. Landlords in Plymouth (PL1, PL2, PL3 and PL4) usually come to us with a council letter, a fire risk assessment or a house they have just bought. We price from whichever you have. With students as well as working sharers renting in Plymouth, we plan bigger jobs for the gap between academic-year tenancies where we can.

Which rules apply in Plymouth?
House to HMO conversion in Plymouth must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- 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.
- Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
