Full guides: HMO licensing in County Durham ↗ · Article 4 directions ↗
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.
See the full Article 4 picture below ↓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.
| 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 |
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 ↗
