Extra legal requirements apply to HMOs.
The property must be used as the tenants' only or main residence to be an HMO and it should only or mainly be used to house tenants.

HMOs need to be well managed and the structure, facilities and equipment within them need to be kept in good repair and well maintained. Specific management regulations apply for this purpose.
The housing fire safety guide (LACORS) also provides useful guidance on the fire safety provisions for certain types of existing housing including HMOs, single dwellings and buildings converted to flats.
In addition the Regulatory Reform (Fire Safety) Order 2005 replaces previous fire safety legislation and requires that the "responsible person" perform a fire risk assessment for the common areas of all HMOs.

By law, HMOs with 5 or more occupants, who share a bathroom, toilet or kitchen must be licenced with us.
It is a serious criminal offence to have a HMO without a licence. It can result in prosecution or a civil penalty.
We aim to work with landlords to help and advise them to meet the HMO standards. We can use our housing enforcement powers if we need to.
You can apply for a licence if you own or manage a HMO.
We keep a public register of all licenced HMO’s which we update regularly.
