Editing Sui generis (section)

===Town planning law===
In [[town and country planning in the United Kingdom]], in particular, relating to the [[Town and Country Planning (Use Classes) Order 1987]], many common types of land use are categorised into specific "use classes". Change of use of land within a use class does not require planning permission; changing between use classes might require planning permission, and approval is always needed if the new use is {{lang|la|sui generis}}.

Examples of {{lang|la|sui generis}} uses include [[embassy|embassies]], [[theatre]]s, [[amusement arcade]]s, [[laundrette]]s, [[Taxicab|taxi]] or [[vehicle hire]] businesses, [[filling station|petrol filling stations]], [[scrapyard]]s, [[nightclub]]s, [[car dealership|motor car showrooms]], retail warehouses, clubs and [[hostel]]s.<ref>{{Cite web |title=Use Classes - Change of use - Planning Portal |url=https://www.planningportal.co.uk/permission/common-projects/change-of-use/use-classes/ |access-date=2024-04-26 |website=www.planningportal.co.uk}}</ref>

The grant of private hire vehicle (taxicab) operators licences by local authorities frequently has a condition that the appropriate ''sui generis'' change of use planning permission is granted to those premises to ensure those businesses cannot trade lawfully without the relevant planning consent.
