National guidance cannot confirm every local scheme, Article 4 direction, planning condition or building history. Give the council a clear description of the current and proposed use, occupancy and works, and keep its written response.
Separate the permission questions
Create a record for each authority or decision relevant to the proposal.
- Planning concerns use and development; building control concerns compliance of controlled work; licensing concerns the letting and occupation. Check each separately.
- Add mortgage, insurance, lease, conservation or listed-building restrictions where relevant. A private consent can matter even when public approval is not required.
- Define the actual proposal: household, room use, number of dwellings and work. Vague enquiries can produce answers that do not cover the final plan.
Get an address-specific answer
Use the council and other responsible bodies' current information.
- Check maps, designations, conditions, expiry dates and exemptions. Keep the exact address and proposed use in correspondence.
- Ask for clarification where a boundary, conversion or previous use makes the answer uncertain.
- Keep historic approvals, but check whether they authorise the present layout and occupation. A former owner's description is not a permission document.
Track conditions through completion
Approval may be subject to work or information that must be supplied before occupation.
- List each condition, owner, due event and evidence needed.
- Review any change in design or household before proceeding, and obtain variations where required.
- Keep completion and discharge-of-condition evidence with the approval. An application reference does not prove that all conditions were met.
Example: planning permission exists for fewer occupants
A fictional property has planning consent but an HMO licence limits its occupation differently. Establish the combined lawful position before offering rooms. Choosing whichever document permits more occupants is not a valid method.
What to do
- Find the current local planning and property licensing information.
- Check the proposed use as well as the existing position.
- Ask building control or the Scottish verifier about the work.
- Resolve uncertain permission before relying on a rental appraisal or advertising rooms.
Evidence to keep
- Dated council sources and written decisions
- Plans, use history and licence conditions
