Birmingham Article 4 Direction: HMO Planning Permission Explained

Birmingham has both a property licensing regime and a city-wide Article 4 direction that removes permitted development rights for HMO conversions. Landlords regularly confuse the two — or assume that getting one means they have the other. They are entirely separate legal systems, administered by different council departments, and you can be penalised for lacking either one independently.

What the Article 4 Direction Does

Since June 2014, Birmingham City Council has enforced a city-wide Article 4 direction under the Town and Country Planning Act 1990. In most of England, converting a standard C3 dwelling into a small C4 HMO (three to six unrelated occupants sharing facilities) is permitted development — no planning application needed. Birmingham's Article 4 direction removes that right across all 69 wards.

The practical effect: converting any residential property in Birmingham into a shared house occupied by three or more unrelated people forming separate households requires formal planning permission. This applies whether you are converting a C3 dwelling to a C4 small HMO or to a larger Sui Generis HMO (seven or more occupants).

The 10% Concentration Rule

When Birmingham's planning officers assess an HMO planning application, they apply Policy DM11 of the Birmingham Development Plan and the Houses in Multiple Occupation Supplementary Planning Document. One of the key thresholds is the 10% concentration rule: if existing HMOs and exempt accommodation already account for more than 10% of residential properties within a 100-metre radius of the application site, the planning application will generally be refused.

This means that even if the property meets every licensing standard, the planning department can refuse the conversion on neighbourhood concentration grounds alone.

Planning Permission vs Property Licence

A property licence is issued by the Private Rented Sector Licensing team under Parts 2 and 3 of the Housing Act 2004. It confirms that the property meets housing standards and that the licence holder is a fit and proper person.

Planning permission is granted by the Planning department under the Town and Country Planning Act 1990. It confirms that the use of the property as an HMO is acceptable in land-use terms — considering neighbourhood character, parking, concentration and other planning matters.

Neither one substitutes for the other. A landlord who holds an additional HMO licence but lacks C4 planning permission (or a Certificate of Lawful Existing Use or Development proving continuous HMO use before June 2014) can receive a planning enforcement notice. That notice can compel the landlord to stop operating the HMO, evict occupants and reinstate the property as a single dwelling — regardless of whether the property licence is valid.

Which Properties Need Planning Permission

Not every licensed HMO needs fresh planning permission. If the property was already in continuous use as an HMO before Birmingham's Article 4 direction took effect in June 2014, the landlord may be able to obtain a Certificate of Lawful Existing Use or Development (CLEUD) to prove that the HMO use predates the restriction.

Properties that were converted to HMO use after June 2014 without planning permission are in breach — even if they have since been licensed. The planning enforcement team can take action on the unlawful change of use at any time.

Selective licensing does not involve planning permission at all. Single-family lets in the 25 designated wards need a selective licence but are not affected by the Article 4 direction because their use class remains C3.

What to Do if You Are Converting

If you are converting a standard house into a shared house in Birmingham, you need to check and satisfy both systems:

1. Apply for C4 (or Sui Generis) planning permission through the planning department before letting to unrelated sharers.
2. Apply for the correct property licence — additional HMO if three to four sharers forming two or more households, mandatory HMO if five or more — through the Private Rented Sector Licensing portal.

Both carry separate fees, separate timelines and separate enforcement consequences.
