Do HMOs need planning permission in County Durham?

We do not hold Article 4 records for County Durham — no source we read publishes them for this council, which is not the same as there being none. Where no Article 4 direction applies, converting a home to a small HMO (up to 6 occupants) is often permitted development, but County Durham council is the authoritative source for whether a direction covers a given address.

When does an HMO need a licence in County Durham?

Nationally, a property let to 5 or more occupants forming 2 or more separate households and sharing a kitchen, bathroom or toilet must hold a mandatory HMO licence — this applies in every council in England, including County Durham. Some councils also run additional or selective licensing schemes covering smaller HMOs; check the current schemes with County Durham council.

What are the minimum room sizes for a licensed HMO?

A mandatory HMO licence enforces national minimum sleeping-room floor areas: 6.51 m² for one person aged over 10, 10.22 m² for two people over 10, and 4.64 m² for a child under 10. These are national statute and apply in County Durham.

Full guides: HMO licensing in County Durham ↗ · Article 4 directions ↗

01 · Planning permission

Article 4 status unknown — we hold no records

We hold no Article 4 records at all for County Durham — no source we read publishes them for this council, which is not the same as there being none. A direction may be in force, so treat this as unknown and check with the council before assuming a conversion is permitted development.

02 · Licence to operate

Mandatory HMO licence National

5 or more occupants forming 2 or more separate households

Any HMO occupied by five or more people making up two or more separate households (sharing a kitchen, bathroom or toilet) must hold a mandatory HMO licence. This applies in every council in England, regardless of the number of storeys.

No Additional or Selective licensing scheme in our records for County Durham. Many boroughs operate schemes that extend licensing to smaller HMOs or all rented homes, and these change on five-year cycles — check the council's current designation via the gov.uk licence finder ↗.

03 · Minimum room sizes

One person aged over 10	6.51 m²
Two people aged over 10	10.22 m²
One person aged under 10	4.64 m²
Any sleeping room	≥ 4.64 m²

Kitchen, bathroom & WC standards

Licensed HMOs must provide adequate, well-located cooking, washing and toilet facilities for the number of occupants, plus safe gas/electrics, working fire detection and proper waste storage. The exact ratios (occupants per bathroom, per WC, kitchen size) are set by each council in its own HMO amenity standards — confirm the figures with the borough before committing to a scheme.

Minimum room sizes and the mandatory-licensing threshold are national law (Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018), sourced under the Open Government Licence v3 — they apply in every council. Licensing designations shown are those in our records; verify the current position and exact amenity standards with County Durham Council before relying on this. gov.uk: HMO licences ↗
