Where should I start?

Why an address-level check is necessary
Two apparently similar properties can have different planning histories, constraints and rights. A description such as “terrace in Headingley” is not enough to determine whether a particular extension or change of use is lawful. The exact property boundary, existing building and proposed works matter.
Check the council map and records, applicable directions and the decision history. Previous conditions may restrict rights. Conservation-area status and listed-building status are separate designations, and their implications depend on the works.
Turn the shortlist into a decision
Gather accurate dimensions, dated plans and photographs, previous decisions and any evidence of use. Read the applicable national permitted-development provisions alongside the local constraints. If certainty is needed, discuss the appropriate lawful development certificate route.
The selections below only identify a starting point. They do not query live council data, assess all statutory conditions or substitute for advice on the actual proposal.
Your questions, answered
Does this check my postcode against Article 4?
No. It explains the relevant first step and links to the Leeds Article 4 guide and official mapping.
Can I start works after using this tool?
No. Establish the appropriate consent or lawful basis for the actual project first.
