Astor analyst's read

York — 231 applications in last 12 months; 3 Article 4 directions in our records (1 HMO-specific).

Profile

Historic cathedral city; mixed Georgian, Victorian and modern stock; moderate density; strong conservation character throughout.

Planning

3 active Article 4 directions in our records (1 HMO-specific); verify council coverage as only 7 of 231 applications decided to date.

Deal angle

Limited data on approval pace (only 7 decisions from 231 received); HMO-specific A4 footprint appears light, but council verification essential before proceeding.

Full guides: HMO licensing in York ↗ · Article 4 directions ↗

01 · Planning permission

See the full Article 4 picture below ↓

02 · Licence to operate

Mandatory HMO licence National

5 or more occupants forming 2 or more separate households

Any HMO occupied by five or more people making up two or more separate households (sharing a kitchen, bathroom or toilet) must hold a mandatory HMO licence. This applies in every council in England, regardless of the number of storeys.

No Additional or Selective licensing scheme in our records for York. Many boroughs operate schemes that extend licensing to smaller HMOs or all rented homes, and these change on five-year cycles — check the council's current designation via the gov.uk licence finder ↗.

03 · Minimum room sizes

One person aged over 10	6.51 m²
Two people aged over 10	10.22 m²
One person aged under 10	4.64 m²
Any sleeping room	≥ 4.64 m²

Kitchen, bathroom & WC standards

Licensed HMOs must provide adequate, well-located cooking, washing and toilet facilities for the number of occupants, plus safe gas/electrics, working fire detection and proper waste storage. The exact ratios (occupants per bathroom, per WC, kitchen size) are set by each council in its own HMO amenity standards — confirm the figures with the borough before committing to a scheme.

Minimum room sizes and the mandatory-licensing threshold are national law (Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018), sourced under the Open Government Licence v3 — they apply in every council. Licensing designations shown are those in our records; verify the current position and exact amenity standards with York Council before relying on this. gov.uk: HMO licences ↗
