Do HMOs need planning permission in Croydon?

Croydon has 1 active Article 4 direction 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.

When does an HMO need a licence in Croydon?

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 Croydon. Some councils also run additional or selective licensing schemes covering smaller HMOs; check the current schemes with Croydon 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 Croydon.

Astor analyst's read

Croydon — high-volume planning authority (3,076 apps in 12m); 1 HMO Article 4 in our records — verify council holdings.

Profile

Outer London suburban borough with mixed-density stock; significant residential and commercial activity; strong application throughput.

Planning

1 HMO-specific Article 4 direction in our records; robust application volume (3,076 in 12m) suggests active but opaque approval climate — council verification on A4 footprint essential.

Deal angle

Single HMO A4 on our data is likely incomplete; high application throughput offers liquidity but regulatory read unclear without full council Article 4 mapping.

Two people aged over 10	10.22 m²
One person aged under 10	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 Croydon Council before relying on this. gov.uk: HMO licences ↗
