Harrow HMO & Article 4 planning

0 applications in the last 12 months

Astor analyst's read

Harrow — 1 HMO-related Article 4 direction in our records; minimal recent application activity.

Profile

Outer London suburban borough, mixed density, family-oriented stock with significant terraced and semi-detached properties.

Planning

One HMO-specific Article 4 direction recorded in our database; verify current scope and coverage with Harrow Council planning as our sync may be incomplete.

Deal angle

Single HMO Article 4 restricts standard multi-let conversions in affected zones; thin recent activity suggests either established stock or constrained market opportunity — verify council for current designation footprint.

01 · Planning permission
Planning permission required for small HMOs

An Article 4 direction removes permitted development rights for small HMOs (C3→C4) across the whole borough 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.

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