Dwellinghouses (C3) to small HMOs (C4) - borough-wide Article 4 Direction. Named permitted development rights are withdrawn here.
An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.

The council has declared the area as failing an air quality objective.
