Haringey Article 4 Direction: HMO Planning Permission Explained

The Trap: Licensing and Planning Are Separate Systems

One of the most expensive mistakes Haringey landlords make is assuming that a property licence gives them planning permission. It doesn't. Property licensing operates under Parts 2 and 3 of the Housing Act 2004. Planning permission operates under the Town and Country Planning Act 1990. They run on separate legal tracks, administered by different council teams, with different requirements.

A landlord can hold a valid HMO licence from Haringey's Private Sector Housing team while simultaneously breaching planning law. The council's planning enforcement team can and does issue enforcement notices requiring a property to revert to single-family use — even when the licensing team has granted a licence for the same building as an HMO.

What the Article 4 Direction Does

Normally in England, converting a single-family house (Use Class C3) into a small HMO occupied by three to six unrelated people (Use Class C4) is permitted development — no planning application needed. The change happens automatically under national Permitted Development Rights.

Haringey's Article 4 Direction, in force since 30 November 2013, removes this automatic right in 14 designated wards: Bounds Green, Bruce Castle, Harringay, Hermitage and Gardens, Noel Park, Northumberland Park, Seven Sisters, South Tottenham, St Ann's, Tottenham Central, Tottenham Hale, West Green, White Hart Lane, and Woodside.

In these wards, converting a C3 dwelling into a C4 small HMO requires a full planning application under Policy DM17 of Haringey's Development Management DPD. The seven western wards are unaffected — permitted development still applies there for C3-to-C4 conversions.

For large HMOs (seven or more occupants), the planning position is simpler but more restrictive: these are classified as Sui Generis use and always require planning permission, everywhere in the borough, regardless of Article 4.

How This Affects You in Practice

If you're converting a family house to a small shared let (3–6 sharers) in one of the 14 wards: you need planning permission before tenants move in, even if you already hold or intend to apply for an HMO licence. Without planning permission, you risk a planning enforcement notice ordering reversion to single-family use.

If the property has been operating as an HMO since before 30 November 2013: the Article 4 Direction doesn't apply retrospectively to existing uses. You can apply for a Certificate of Lawfulness for an Existing Use or Development (CLEUD) to confirm the property's legal planning status. The same applies if the HMO use has been continuous for over 10 years without enforcement — this establishes immunity under the planning time limit.

If the property is in one of the seven western wards: permitted development still allows C3-to-C4 conversion without a planning application. But remember, a large HMO (7+) needs planning permission regardless.

The Licensing-Planning Matrix

Here's how the two systems interact for a property in one of the 14 Article 4 wards:

Single household or two sharers: needs a selective licence (licensing), no planning change required (planning — still C3 use).

Three to six unrelated occupants: needs an additional HMO licence (licensing), AND needs planning permission for C4 use (planning — Article 4 removes permitted development).

Seven or more unrelated occupants: needs a mandatory HMO licence (licensing), AND needs planning permission for Sui Generis use (planning — always required for large HMOs).

What to Do Before Letting

If you're converting a property to shared use in one of the 14 wards, check the planning position first:

1. Search Haringey's planning records for any existing HMO planning consent on the property
2. If the property has been used as an HMO continuously, consider whether a CLEUD application is appropriate
3. If no planning consent or lawful use exists, submit a planning application before starting the licensing application
4. Apply for the appropriate property licence once planning is in order

Getting this sequence wrong is costly. A planning enforcement notice can require you to stop letting to multiple tenants, even while your HMO licence remains technically valid.
