Common landlord planning breaches and the LPA's enforcement toolkit

Planning breach = development without planning permission (TCPA 1990 s.55) or breach of planning condition. Common landlord breaches: (1) C3→C4 HMO conversion in Article 4 Direction area (no permitted development right where A4D applies); (2) C3→C5 short-term let conversion where LPA has designated an area requiring planning permission (England from April 2024); (3) extension/outbuilding exceeding PD limits (height; size; coverage; proximity to boundary — GPDO 2015); (4) breach of planning conditions (using property beyond permitted use; failing pre-commencement conditions; unapproved materials). LPA tools: PCN (formal information request; 21 days to respond; criminal offence to fail); BCN (condition breach; faster; minimum 28-day compliance; unlimited fine for non-compliance); Enforcement Notice (main tool; specifies breach; requires steps; compliance period; 28-day appeal suspends notice); Stop Notice (requires immediate cessation; LPA pays compensation if withdrawn or quashed; rarely used); High Court injunction (s.187B TCPA 1990; contempt if breached).

  • Article 4 Directions: C3→C4 HMO conversion requires planning permission in A4D areas — check with LPA before converting any dwelling to HMO in an A4D area
  • PCN failure: criminal offence (fine up to £1,000); providing false information: unlimited fine — respond fully within 21 days
  • Enforcement notice: 28-day appeal lodged with Planning Inspectorate suspends notice — landlord not required to comply and LPA cannot enforce during appeal
  • Stop Notice: requires immediate cessation; LPA faces compensation liability if stop notice withdrawn or quashed — LPAs are cautious about serving stop notices

Limitation periods, Certificate of Lawful Use and appeal procedure

TCPA 1990 limitation periods: (1) Building operations (extensions; structural works): 4 years from substantial completion; (2) All other breaches including change of use (C3→C4 HMO; C3→C5 short-term let; any material change in use) and breach of planning conditions: 10 years from date breach FIRST occurred. After limitation period: breach immune from enforcement; apply for Certificate of Lawful Use or Development (CLU) on Form 1APP to LPA (same fee as householder application; 8 weeks to determine) to confirm immunity — valuable for sale and mortgage purposes. Appeal against enforcement notice to Planning Inspectorate within 28 days: grounds include (a) planning permission ought to be granted (deemed application — if inspector grants PP, notice falls away); (b) breach not occurred; (c) notice improperly served; (d) steps excessive; (e) compliance period too short. Criminal liability for non-compliance after notice takes effect: unlimited fine (s.179 TCPA 1990); LPA direct action at landowner's expense.

  • 10-year limitation for HMO use change: if property has been used as HMO for 10+ years without planning permission, breach is immune — apply for CLU to confirm lawfulness
  • 4-year limitation for building operations: extensions substantially completed 4+ years ago are immune from enforcement — CLU confirms lawfulness for sale/mortgage purposes
  • CLU: registerable as land charge; passes to future buyers; lenders typically require CLU before mortgage lending on property with unresolved planning breach
  • Appeal suspends notice: use 28-day appeal window to take planning/legal advice; simultaneous retrospective planning application for the breach is possible during appeal
