Evidence status: This is an independent explanation of a published government dataset entry. It is not confirmation that this direction is operative, that a particular building lies within it or that a licence is required. The signed council instrument and mapped boundary take precedence over this page.

Associated mapped areas

The following area entities reference this direction within the same source organisation. Their coordinates are approximate representative points; the actual boundary must be checked using the government's full geometry and the signed council map.

How to use this evidence for an HMO investment

  1. Identify the correct full address and existing lawful use. A change from a dwellinghouse (C3) to a small HMO (C4) can raise a different question from a large sui generis HMO.
  2. Read the linked council document, not only this catalogue entry. Identify the precise permitted-development rights withdrawn, confirmation or effective date, exceptions and exact mapped boundary.
  3. Compare the distinct mapped area records above, then obtain the authoritative map for the actual building footprint.
  4. Check any existing planning permissions separately from mandatory, additional and selective HMO licensing obligations; these are different regimes.
