How To Convert Your Property into a HMO

A house in multiple occupation, better known as HMO, is a property that is rented to three or more tenants, who aren’t part of the same household, that share amenities. 

The good news, HMO’s provide more people with affordable accommodation, while generating a rental income increase of four to five times your current return – compared to a single tenanted property.

If you are considering converting your current property into an HMO, here’s what how to do it.

Step 1: Location, location, location

Before you consider converting your property to an HMO, check that it is in the right location. For example, a busy student area or close to good transport connections.

Step 2: HMO Licensing

A critical legal aspect of letting an HMO is getting the relevant licence. If you’re letting an HMO, it’s highly likely you’ll need some sort of licence to ensure that the property:

  • is safe for tenants to live in
  • is in good condition
  • has an adequate number of smoke detectors
  • has appropriate fire exits
  • has enough sinks, cookers, baths and toilets for the number of tenants
  • is well managed

To check if your property needs to be licenced, you can contact your local council. Or speak to us about our HMO Licensing service, which includes applying for the local Council’s property licensing scheme on your behalf.

Step 3: Safety Compliance

There are various compliance measures you’ll need to meet to let an HMO. This includes:

  • getting an annual gas safety certificate
  • installing the required number of smoke alarms and carbon monoxide detectors 
  • getting safety certificates for electrical appliances
  • keeping exits clear from obstructions and marking fire exits clearly
  • providing emergency lighting for fire safety

Step 4: Minimum Room Size Requirements

Your HMO property will need to comply to the following minimum HMO room sizes:

  • No room less than 4.64 square metres can be used as sleeping accommodation. This size can only be used by one person aged under 10 years 
  • A room size of 6.51 square metres minimum, can only be used by one person aged over 10 years
  • A room size of 10.22 square metres minimum, can only be used by two persons aged over 10 years

Depending on your local council, there may be other criteria to meet.

Step 5: Converting to an HMO

You may need to adjust make your property suitable for three or more tenants from separate households to rent.

The key areas to focus on in the conversion is providing sufficient space, a good layout, the right facilities, good furniture and reliable appliances.

For example, if you own a three-bedroom house, this can typically be converted into six units with the following suggested conversions:

  • Adding a loft unit on the second (or third) floor 
  • Extending the rear of the property to add a unit (if the backyard is large enough)
  • Converting existing living areas into separate units
  • Installing ensuites and kitchenettes in all units
  • Converting the current kitchen to a communal kitchen and laundry
  • Converting the garage into an additional living space

You may need to move or construct walls to alter room sizes or add plumbing to “spare” rooms to create a shared bathroom. 

Whatever works are needed, we recommend engaging a professional. Remember, you may also need planning permission for the renovations.
