Off- and on-street parking are different beasts! The TROs are made under different sections of the RTRA and the contravention codes and the wording of PCNs and ‘notices to owner’ for enforcement vary. For an off-street order you don’t define where the bays are – you just reference the whole car park. In two-tier areas, off-street is usually a district council responsibility, whereas on-street is county (unless formally delegated).
