HMO bedroom size checker

Check a bedroom against the national minimum sleeping room sizes for a licensed house share, leaving out any area under a low ceiling.

The minimum bedroom sizes for a licensed HMO

A licensed house in multiple occupation must meet national minimum sleeping room sizes. The rules count only usable floor area, so any part of the room where the ceiling is lower than 1.5 metres is left out. That matters in loft rooms and under sloping roofs.

Who sleeps in the roomMinimum usable floor area
One person aged 10 or over6.51 square metres
Two people10.22 square metres
One child under 104.64 square metres

A worked example

A loft bedroom measures 9.4 square metres on the floor, and 1.6 square metres of it sits under a ceiling lower than 1.5 metres. The area that counts is 7.8 square metres. That meets the 6.51 square metre minimum for one adult, but it is far short of the 10.22 square metres needed for two people. In a house share we never let a room to a couple for exactly that reason, and because a second person in a room can take the house to five occupiers and trigger a licence.

Where this fits

Room size is one part of HMO licensing, alongside fire safety, the Management Regulations and planning permission under the Article 4 Direction that applies across Tameside. Our HMO licence guide covers the whole picture, and our HMO management service runs licensed house shares for landlords in Ashton-under-Lyne, Stalybridge, Hyde and across Tameside.

Questions

Common questions

What are the minimum bedroom sizes for an HMO?

For a licensed HMO the minimum is 6.51 square metres for one person aged 10 or over, 10.22 for two people and 4.64 for a child under 10.

Does the whole floor count?

No. Any area where the ceiling is lower than 1.5 metres is not counted when you measure the room.

Does a bigger room mean a licence is not needed?

No. A licence depends on how many people from how many households live in the property. Room size is one of the standards a licensed HMO must meet.

Can I let a double room to a couple?

Only if it is at least 10.22 square metres, and remember a second person in a room can take a house to five occupiers, which needs a licence.

Is anything stored or sent when I use the checker?

No. It is worked out in your browser and nothing is stored or sent anywhere.
