An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. Landlords in Chichester (PO19 and PO20) 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. Chichester has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.

Which rules apply in Chichester?

- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
- The Fire Safety Order 2005 applies to the common parts of HMOs, enforced by the fire and rescue authority.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
