INDEPENDENT GUIDANCE — not project-specific legal/design advice or a compliance certificate. Check the official current requirements and applicable transition.

A central framework for controlling development, planning permissions, conditions and enforcement. For an England project, determine whether the proposal is development and how it is authorised. Permission may depend on local policy and conditions; Building Regulations approval and land ownership are separate matters.

WHAT TO CHECK
[ ] Establish the existing lawful use, proposed operations and relevant site constraints.
[ ] Check whether permission is needed, already exists or is provided by a valid permitted-development route.
[ ] Review the local plan, relevant national policy and the authority's application information requirements.
[ ] Track every condition, approved drawing and obligation affecting start, construction or occupation.
[ ] Check the correct procedure for amendments and keep written confirmation instead of relying on informal assumptions.

RECORDS TO KEEP
- Planning history, constraints search and lawful-use evidence.
- Decision notice, approved drawings and applicable conditions or obligations.
- Condition-discharge and amendment decisions linked to site revisions.

WHEN TO GET SPECIALIST HELP
Seek planning advice from the local authority or a competent planner for uncertain lawful use, conditions, enforcement or material changes before committing to work.
