Planning Portal And Council Route Checker
This page is built for searches about house extensions in Yorkshire. It gives you the local reading first, then sends you to the guide most likely to answer the remaining question.
If the search is still broad in Yorkshire, open the county guide first, then follow the project or topic page that resolves the remaining doubt fastest.
Use The Official Portal, Then Pick The Project Route
Working answer
Use this hub when a planning portal search needs to become an official council source check and then a project-specific planning route.
Checks most likely to change it
- Start with the official council portal or validation source.
- Move into the project guide as soon as the build type is clear.
- Check conservation, Article 4, HMO or validation controls before relying on a broad council result.
Best next move
Use the council route for orientation, then move into the project or topic page that decides the issue.

Working answer
This search is usually a starting query rather than a final answer. Use it to reach the county guide first, then the strongest project or planning-topic page once the real blocker is clearer.
Why this search exists
People search for planning portal council checker when the local route is still broad. This page turns that broad query into a short list of authority, topic and project pages that are actually worth your time.
Best next step
Start with the county page if the search is still broad, then move into the strongest project or planning topic page as soon as the real blocker is clearer.
The Checks Worth Making Before You Pay For More Work
Main local signal
Some house extensions can be permitted development in England under Class A, but the answer depends on whether the proposal is rear, side or two storey, whether it stays behind the principal elevation and whether the house remains within the 50% curtilage limit. Around historic cores and mixed streets, roof form, brick detailing and how the work meets the original house can matter as much as the raw permitted development measurements.
Checks most likely to matter
- Conservation areas can change the answer faster than the broad search query suggests.
- Listed buildings can change the answer faster than the broad search query suggests.
Before you spend money
Use this page to narrow the question first, then spend time on the main guide that resolves it. Broad local queries are useful for orientation, but they are a weak basis for drawings, quotes or an application strategy on their own.
Open The Page Most Likely To Settle The Remaining Question
Treat this as a short route map: county guide first, then the strongest project or local rule page, then a process FAQ or tool if the answer still needs tightening.

When A Broad Local Search Stops Being A Safe Stopping Point
When to escalate
If the proposal is borderline, affected by special controls or financially sensitive, use the linked pages to narrow the issue and then move to a lawful development certificate, pre-application advice or another formal check before relying on assumptions.
Formal checks that often help
- Use a lawful development certificate when the project only works if the simpler route still holds up.
- Use pre-application advice when the design is sensitive, locally constrained or already drifting toward a full application.
- Keep measured drawings, site photos and planning-history notes together before you rely on any borderline answer.
How to use this page well
Treat this as a starting point, not a stopping point. Its job is to get you to the authority, project, topic and tool pages that make the next real decision easier.
