National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
7 or more sharers is a sui generis large HMO and normally needs planning permission.
A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.

Questions about house to HMO conversion in East Sussex

Do I need planning permission to turn a house into an HMO?

It depends on the nation, the council and the number of sharers. In England, three to six unrelated sharers is use class C4, and moving from a family house is usually permitted development unless the council has an Article 4 direction; seven or more normally needs permission. In Wales a change to an HMO always needs permission, in Northern Ireland all new HMOs need it, and in Scotland council policy decides. We check the address before drawings start.

Will the house pass licensing once the works are done?

We build to the standards your council publishes and give you the certificates and drawings an inspection asks for. The licence decision belongs to the licensing authority, so we never promise approval, but we design to meet the written standards from day one.
