Do HMOs need planning permission in Camden?

Camden has 21 active Article 4 directions in our records. Where an Article 4 direction applies, permitted development rights to convert a home (use class C3) to a small HMO (C4) can be removed, so a full planning application is required. Coverage varies — verify with the council before relying on this.

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 Camden.

Astor analyst's read

Camden — 21 active Article 4 directions in our records; HMO-specific designations not yet captured in our sync.

Profile

Inner London borough, dense Victorian and Edwardian mixed-use stock, strong conservation character, high property values.

Planning

21 active Article 4 directions on record (HMO-related sub-count not yet synced); 873 applications in last 12 months suggest robust planning activity and a live consent market.

Deal angle

HMO play requires council verification of Article 4 footprint — our records show non-HMO A4s, but Camden's conservation density and historic Article 4 HMO controls are likely material; bridging viable in non-Article 4 pockets.

Full guides: HMO licensing in Camden ↗ · Article 4 directions ↗

01 · Planning permission

No HMO Article 4 in our records

No HMO Article 4 direction in our records for this borough. Where no direction applies, converting a home to a small HMO (C4, up to six occupants) is usually permitted development — but coverage can be incomplete, so verify with the council before relying on this.

See the full Article 4 picture below ↓

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 Camden. 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 Camden Council before relying on this. gov.uk: HMO licences ↗
