Opening an HMO in Southampton: the Article 4 guide

Southampton City Council scores 7 on our strictness scale (1 HMO direction (C3→C4 right removed); HMO direction described as borough/city/town-wide; 10 householder rights also removed (extensions, roofs, exterior)). Below: every HMO Article 4 area it has published, when each came into force, which categories of right the council has removed across all its areas, and an outline of the planning route. Live from planning.data.gov.uk — indicative, verify with the council.

1. Where — the HMO Article 4 areas

One direction is described as covering the whole borough/city — assume every residential address is inside unless the council confirms otherwise.

Boundaries are polygons — a postcode is a point. The free check tells you whether an address is inside one of these areas; the paid report adds the rights each direction removes, the council reference, the direction document and the full planning route for that address.

Limits of this guide
  • Coverage depends on each council publishing its Article 4 Directions to planning.data.gov.uk. 'No Article 4 found' means none is published for this point — it does not prove that none exists. Verify with the local planning authority (LPA) before committing money.
  • A postcode is a point, not a building outline. Properties on the boundary of an Article 4 area can fall either side — confirm the exact address with the LPA.
  • Large HMOs (7 or more occupiers, sui generis) always need planning permission, Article 4 or not. Mandatory HMO licensing (Housing Act 2004) is separate from planning and is not checked here.
  • This report is indicative information from published datasets, not legal or planning advice.
