Walkthrough: an HMO application in an Article 4 area

The concentration count decided this application before a single drawing was produced. The following walkthrough is illustrative: a three-bedroom Victorian terrace in a university city, inside an Article 4 direction area covering four wards, being converted to a six-bedroom house in multiple occupation. The property sat on a street with on-street parking at capacity and a local plan policy capping HMOs at a stated proportion of residential properties within 100 metres.

Nine weeks from validation to committee, one revision, and a permission with seven conditions. The work that mattered happened in the fortnight before submission.

The property, the licensing position and the direction

The Article 4 direction had withdrawn the Part 3 Class L right allowing a change of use between C3 and C4 across the named wards. So a conversion to a six-person shared house needed planning permission even though it stayed within Class C4.

Two checks came first. The direction document itself, read for the classes withdrawn, the effective date and the extent of the area rather than relying on the council's webpage summary. And the planning history of the property, which showed continuous single-family occupation and therefore no argument that an HMO use was already lawful.

Licensing ran alongside and separately. Six sharers in more than one household brings the property within mandatory HMO licensing under the Housing Act 2004, and the city also operated an additional licensing scheme. The licence application was prepared in parallel, with the explicit understanding that a licence would not cure a planning breach and permission would not satisfy the licensing standards.

The concentration policy and the radius it applies over

This is the calculation to do before exchanging contracts, and it took an afternoon.

The policy capped HMOs at a stated percentage of residential properties within a 100 metre radius, measured as a straight-line distance from the application property. The method used:

1. Plot a 100 metre radius on an Ordnance Survey based plan and count every residential property whose front door falls inside it.
2. Count known HMOs inside the radius from the council's published licensing register, cross-checked against planning permissions granted for HMO use.
3. Express the existing HMOs as a percentage, then recalculate including the application property.
4. Compare both figures against the policy threshold.

The result came out below the threshold with the application property included, by a small margin. That margin was the whole case, so the count was submitted as a plan with a numbered schedule of every property, its address and its status, showing the source for each HMO identified. An officer can check that in twenty minutes. A statement asserting compliance without the underlying count cannot be checked, and it invites the officer to do their own count and reach a different answer.

Two properties were arguable: one licensed HMO whose front door fell just outside the radius, and one property with a lapsed licence. Both were declared and treated the unfavourable way, which meant the submitted figure was the worst case rather than the best.

The parking stress survey and its methodology

The street was visibly full most evenings, so the parking evidence mattered more than the policy argument.

The survey followed the Lambeth methodology: kerb capacity measured along every street within 200 metres, then vehicle counts on two nights, one midweek and one at the weekend, both between 00:30 and 05:30 when overnight parking demand is at its peak. The survey was carried out in late October, a neutral month avoiding school holidays and the start of the academic year.

Stress came out at 88 per cent on the application street and 79 per cent across the wider survey area. Above 85 per cent is generally treated as saturated. On its own that reads badly, so the submission did three further things: it recorded the existing property's own parking demand as a family house, it set out the absence of any off-street provision either before or after, and it proposed a car-free condition with a management commitment not to let rooms to car-owning tenants.

That last measure is imperfect, and the honest position is that a car-free condition on an HMO is hard to enforce. Saying so in the statement, and offering a management plan with tenancy clauses, went further with the officer than pretending the condition was watertight.

Room sizes, amenity space and refuse storage

The drawings did the work here. Every room dimensioned, areas scheduled in m², and a clear statement of six lettable rooms for six occupants.

What the council's HMO standards required, and what the scheme provided:

• A communal living room in addition to the kitchen, retained at the rear of the ground floor rather than converted to a sixth bedroom. Converting it would have lost the application.
• Kitchen facilities, washbasins and sanitary provision at the ratios in the council's standards, which meant an additional shower room at first floor.
• Bedroom areas above the statutory minimum sleeping room sizes for licensed HMOs, with areas under low head height excluded from the measurement.
• Rear yard retained as usable amenity space, with the cycle store and bin store positioned so they did not fill it.

The bin store was drawn at 1:50 with the number and capacity of bins the council issues for a six-person household, sited behind the front boundary wall with a gate to the pavement so bins could be presented without crossing the neighbour's frontage. That detail appeared in two of the fourteen objections and the officer's report quoted the drawing directly.

Objections from the street and the officer's assessment

Fourteen objections arrived, and they grouped into four themes: parking, refuse, noise and anti-social behaviour, and the cumulative change in the character of the street. Only the first three are material planning considerations in the form they were put, and character was material only through the concentration policy.

The officer's report worked through each. Parking was accepted as harmful but weighed against the car-free condition and the absence of any change in off-street provision. Refuse was resolved by the drawn store. Noise was addressed through a management plan condition rather than an acoustic report, which was proportionate for a six-bed C4 use. Character was resolved by the concentration figure falling below the policy threshold.

A Planning Statement engaging the adopted policies by number, with the concentration schedule and the Parking Survey as appendices, is what allowed the officer to write that report quickly. The recommendation was approval.

The committee decision and the conditions

The application went to committee because a ward councillor requested it, and the debate ran for eighteen minutes on parking and on whether the concentration policy threshold should be applied more strictly than its wording allowed. Members voted to approve in line with the recommendation.

Conditions imposed:

• Development in accordance with the approved plans.
• Occupation limited to no more than six persons, in no more than six lettable rooms.
• Cycle and refuse stores provided before first occupation and retained thereafter.
• A management plan submitted and approved before occupation, covering refuse, noise, tenancy conditions and a contact for complaints.
• The car-free provision.
• Retention of the ground floor communal room as communal space.

Every one of those conditions has to be discharged or complied with, and the management plan condition in particular needs a document submitted and approved before anyone moves in. The sequence for discharging pre-commencement conditions applies equally to pre-occupation conditions, and treating them as paperwork to deal with later is how a lawful conversion becomes an unlawful occupation. Validation itself repays the same attention, and the discipline described in a five-plot infill taken through validation applies to a single terraced house just as much.
