What is the planning approval rate in York?

87.4% of householder planning applications were approved in York over 2025 Q2 to 2026 Q1, from 619 decisions. 78 were refused. These are the council's own statutory returns, not an estimate. Most people guess far lower, which is why plenty of good projects never get submitted at all.

Do I need planning permission for an extension in York?

Often not. Many single storey rear extensions fall under permitted development, a national grant of permission you do not apply for. Article 4 directions in parts of York remove that, though. The Project Calculator will tell you which side of the line your project sits on in about a minute.

How long does planning permission take in York?

93.8% of householder decisions here were made within the eight week target, comfortably ahead of the national picture. Add three to six weeks before that for survey, design and validation. Realistically, expect twelve to eighteen weeks from first call to a decision you can build from.

Is there an Article 4 direction in York?

Yes. 4 directions are published for York on the government Planning Data platform. Check whether your address falls inside one before you spend anything on design.

How many applications get refused in York?

12.6%, or 78 in the year. Refusals almost always come down to depth, bulk, overlooking, or a design that reads as bolted on rather than part of the house. Nearly all of them can be built in some form after a redesign.

York Planning Permission: 87.4% Approval Rate (2026)

What the numbers actually say

Householder planning in York is far more predictable than most people assume. Over 2025 Q2 to 2026 Q1 the council decided 619 householder applications and approved 87.4%. 78 were refused. That puts it 12 of 15 in Yorkshire and the Humber on approval rate.

Speed is the other half of the story. 93.8% of those decisions landed inside the eight week statutory target, comfortably ahead of the national picture.

Permitted development here

York has 4 Article 4 directions published on the government Planning Data platform. Inside those boundaries permitted development is withdrawn, so work that would be automatic elsewhere needs a full application.

35 conservation areas are mapped in York. Inside one you lose roof extensions under Class B entirely, and you lose the larger rear extension route.

The route most people miss

46 larger householder extension applications were made here in the year. That is the prior approval route which lets a terraced or semi detached house go beyond three metres without a full application, and 63.0% of them got through. It is a genuinely usable route and most homeowners have never heard of it.
