An Article 4 Direction is a planning tool used by local authorities in England to remove specific permitted development rights within a defined area. When a council makes an Article 4 Direction relating to houses in multiple occupation (HMOs), it means that planning permission is required before a residential property can be converted into a shared house. Without the direction, this conversion would be allowed automatically under permitted development rights.
This guide explains how Article 4 Directions work, why councils use them, and what they mean for landlords and property investors.
Under the Town and Country Planning (General Permitted Development) (England) Order 2015, certain changes of use are allowed without needing to apply for planning permission. One of the most significant for the rental sector is the change from Use Class C3 (dwelling house) to Use Class C4 (house in multiple occupation for 3 to 6 people).
This means that, in most parts of England, a property owner can convert a family home into a shared house occupied by up to six unrelated people without applying for planning permission. The conversion happens as a permitted development right.
An Article 4 Direction removes this specific right. Once a direction is in force, planning permission must be obtained before making the C3 to C4 conversion.
Councils typically introduce Article 4 Directions in areas where the concentration of HMOs has become a concern. Common reasons include:
Protecting community balance. When a high proportion of properties in a street or ward are converted to HMOs, the character of the area can change significantly. Fewer families remain, school rolls decline, and local services shift to serve a transient population.
Managing environmental impact. High concentrations of HMOs can lead to increased waste, parking pressure, and antisocial behaviour. Councils use Article 4 Directions to manage these impacts by controlling where new HMOs are established.
Preserving housing stock. In areas with high demand for family housing, councils may wish to prevent further loss of family homes to HMO conversions.
Responding to resident concerns. Many Article 4 Directions are introduced following sustained lobbying from residents who have experienced the effects of HMO clustering in their neighbourhoods.
A council can make an Article 4 Direction under section 4 of the Town and Country Planning (General Permitted Development) (England) Order 2015. The process involves:
Consultation. The council must give notice of the proposed direction and allow representations. For non-immediate directions, there is a 12-month notice period before the direction takes effect.
Confirmation. After considering representations, the council confirms the direction. Once confirmed, it comes into force on the specified date.
Notification. The council must notify affected landowners and publicise the direction.
There are two types of Article 4 Direction:
| Type | Notice period | Compensation |
|---|---|---|
| Non-immediate | 12 months from notice to effect | No compensation payable |
| Immediate | Takes effect immediately upon making | Compensation may be payable for 12 months |
Most councils use non-immediate directions to avoid the risk of compensation claims. The 12-month notice period means that any property owner who wishes to convert before the direction takes effect can do so without needing planning permission.
If you wish to convert a property from a single dwelling (C3) to a small HMO (C4) in an area covered by an Article 4 Direction, you must apply for planning permission. The council will assess your application against its local plan policies.
Most councils with Article 4 Directions also have local plan policies that set a threshold for HMO concentration. A common threshold is 10% of properties within a defined radius (typically 50 or 100 metres). If the area already exceeds this threshold, the application is likely to be refused.
An Article 4 Direction only applies to future conversions. If your property was already in use as an HMO before the direction came into force, you do not need retrospective planning permission. You may wish to obtain a Certificate of Lawful Existing Use from the council to confirm this.
An Article 4 Direction is a planning restriction. HMO licensing is a separate housing regulation under the Housing Act 2004. Even if you obtain planning permission for an HMO, you may still need a mandatory or additional HMO licence depending on the number of occupants and the council's licensing schemes. Both requirements must be checked independently.
As of June 2026, approximately 173 councils in England have active or incoming Article 4 Directions restricting C3 to C4 conversions. Coverage varies significantly:
Borough-wide directions cover the entire council area. Examples include Oxford, Nottingham, and Manchester.
Partial directions cover specific wards, streets, or zones within the council area. Examples include Leeds (selected wards), Sheffield (selected areas), and Bristol (specific zones).
Some councils in Wales, Scotland, and Northern Ireland also have equivalent restrictions, though the legal framework differs.

| Article 4 Direction | HMO Licensing | |
|---|---|---|
| What it controls | Change of use from C3 to C4 | Standards and management of existing HMOs |
| Legal basis | Town and Country Planning Act 1990 | Housing Act 2004 |
| Who administers it | Planning department | Housing/environmental health department |
| When it applies | Before converting to an HMO | Once a property is already an HMO |
| Penalty for breach | Enforcement notice, potential prosecution | Criminal offence, civil penalties up to £40,000, rent repayment orders |
No. It simply requires planning permission for the conversion from C3 to C4. If planning permission is granted, the conversion can proceed. Existing HMOs are not affected.
Potentially, yes. Planning permission (if required under the Article 4 Direction) deals with the change of use. An HMO licence deals with the ongoing management and safety standards of the property once it is occupied as an HMO. These are separate legal requirements administered by different council departments.
Yes. Councils can modify or revoke Article 4 Directions at any time. If the direction is revoked, permitted development rights are restored and planning permission is no longer required for C3 to C4 conversions. Set up a Tuxa property alert to be notified if this happens.
Large HMOs (Use Class Sui Generis, 7 or more people) always require planning permission regardless of whether an Article 4 Direction is in place. The Article 4 Direction specifically addresses small HMOs (3 to 6 people, Use Class C4).
