Astor analyst's read

Camden — Grade B+ for HMO; 22 active Article 4 directions in our records (1 HMO-specific) suggest council controls but verify with planning authority.

Profile

Inner London, dense Victorian terrace stock, high-value conservation areas, mixed residential and commercial character — core bridging and HMO territory.

Planning

22 active Article 4 directions in our records indicate heavy regulatory footprint; only 1 flagged as HMO-specific, so verify conservation-area or wider HMO restrictions directly with council.

Deal angle

Strong HMO candidate despite thin A4 HMO metadata; 346 applications annually signals active planning market, but Article 4 footprint demands pre-deal council direction check.

HMO Requirements in Camden

What it takes to run a House in Multiple Occupation in Camden — whether you need planning permission, the licence the property must hold, and the statutory minimum room sizes. Verify current details with the council before committing.

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

01 · Planning permission
Planning permission required for small HMOs

An Article 4 direction removes permitted development rights for small HMOs (C3→C4) in 1 designated area in our records — converting a family home to a small HMO needs full planning permission here. Confirm whether your property falls within the designated area.

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 ↗
