Supported housing and the Class C2 or C3 boundary

Whether supported housing falls in Class C2 or Class C3 turns on the level of care provided and whether the residents live together as a single household. Not on the number of bedrooms, not on whether the flats are self-contained, and not on who owns the freehold. Two identical six bed houses on the same street can sit in different use classes because one runs a rota of waking night staff and the other has a support worker calling for two hours a day.

That is why the question cannot be answered from a floor plan. It is answered from the care specification, the staffing model and the occupancy agreements, and a submission that does not include those three documents is asking the case officer to guess.

What Class C2 covers

Class C2 of the Use Classes Order 1987 is headed residential institutions. It covers use for the provision of residential accommodation and care to people in need of care, other than a use within Class C3, together with use as a hospital or nursing home and use as a residential school, college or training centre.

The phrase that does the work is other than a use within Class C3. Class C2 is residual in this respect, so you test Class C3 first and only reach Class C2 if the use falls outside it.

Care has a defined meaning. Article 2 ties it to need arising from old age, disablement, dependence on alcohol or drugs, or mental disorder, and it extends to the personal care of children and to medical care and treatment. A warden service, a cleaner, a meals delivery and an alarm pull cord are not care within that definition, which is why sheltered housing with a scheme manager is usually ordinary Class C3.

Where supported living remains Class C3

Class C3(b) covers use by not more than six residents living together as a single household where care is provided to residents. Class C3(c) does the same where no care is provided and the use is not within Class C4.

So a small supported living scheme can be Class C3 even with a substantial care package, provided two things hold. Six residents or fewer. And genuine single household living.

Single household is the harder limb and it is a question of fact. Indicators pointing towards it include shared cooking and eating, a shared living room used in common, residents choosing to live there and holding their own tenancies, staff who are not resident, and an arrangement with some permanence rather than a short assessment placement.

Indicators pointing away from it include locked bedroom doors with separate kitchenettes, a staff office and sleep-in room, individual care plans delivered separately with no communal life, rapid turnover, and residents placed rather than choosing. None of these is decisive on its own. Together they describe the character of the use, which is what a decision maker is assessing.

Level of care as the determining factor

Take the two limbs together and a useful way to think about it emerges. Class C3(b) contemplates a household that happens to receive care. Class C2 contemplates an establishment whose purpose is the provision of care, in which people happen to live.

Ask what would happen if the care provider withdrew tomorrow. If the residents would carry on living there as a household, you are probably in Class C3. If the building would empty, you are probably in Class C2.

That last row is why authorities care. A building in Class C3(b) can revert to a family house with no application at all, because it stays within the class. A Class C2 building cannot, so the council retains control.

Extra care and retirement schemes

Extra care housing is the most argued category. Self-contained flats with their own front doors, a care team on site 24 hours, communal facilities, and occupancy tied to an assessed care need.

Practice varies, and authorities commonly treat schemes with a substantial contracted care package and communal facilities as Class C2, while treating age-restricted flats with an optional care offer as Class C3. Some schemes are properly sui generis, falling within neither class because they combine independent living with an institutional care operation.

Do not fight for a label. Describe the use precisely in the application, say which class you consider it falls within and why, and offer a condition that fixes the operating model. An inspector confronted with an honest description and a workable condition rarely gets stuck on nomenclature. An inspector confronted with a claim that the scheme is Class C3 because the flats have kitchens will get stuck immediately.

Affordable housing and levy consequences

The classification has money attached, which is why it is contested.

Affordable housing policies are often drafted around dwellings or Class C3 development, and where they are, a Class C2 scheme may fall outside the requirement. Others catch all residential development, or set a bespoke extra care requirement. Read the policy wording rather than the summary table in the plan.

The Community Infrastructure Levy depends on the charging schedule. Rates are set by use and many schedules treat institutional development differently from housing, sometimes at a nil rate. Check the current schedule for the authority, because rates are indexed and revised.

Housing land supply is a third consequence. Class C2 bedspaces are counted through a ratio rather than as dwellings, which affects both the authority's monitoring and the weight given to the scheme's housing contribution. Where you are arguing that a Class C2 scheme meets housing need, say how, and put the arithmetic in the Affordable Housing Statement rather than leaving it in a covering letter.

Conditions tying occupation to care need

A condition restricting occupation to people in need of care is standard, and badly drafted versions of it fail on appeal.

Three drafting points. Define care by reference to the Use Classes Order definition rather than inventing a new one. Say who assesses the need and on what basis, because a condition depending on an undefined assessment is unenforceable. And deal with spouses, partners and dependants living with a resident, or you create a condition that cannot be complied with.

Where the restriction needs a nomination agreement, a care provider covenant or an affordability element, that belongs in a section 106 agreement with the condition cross-referring to it.

Evidence of the care package

Submit five documents. A care specification setting out hours per resident per week and the tasks covered. A staffing rota showing day and night cover. A specimen occupancy agreement, tenancy or licence. The referral or nomination route. And a schedule of communal facilities with their floor areas.

Then write two paragraphs in the Planning Statement explaining how those documents answer the single household question and the level of care question. As an illustrative example, a five bedroom house with five assured shorthold tenancies, a shared kitchen and living room, and 14 hours of support per resident per week from a visiting team, reads as Class C3(b). The same house with five licences, five kitchenettes, a staff sleep-in room and 24 hour on-site cover does not.

Where the existing lawful use is unclear, that has to be settled first, and evidencing a lawful use where the history is silent sets out how. A lawful development certificate is the only formal way to confirm the position.
