Permitted development removed by a planning condition

A condition on your planning permission can switch off permitted development rights that would otherwise apply to the house, and most owners discover it two years after completion when they start pricing an extension. The mechanism sits in article 3(4) of the Town and Country Planning (General Permitted Development) (England) Order 2015: permission granted by the Order does not apply where it would be contrary to a condition imposed on a planning permission granted under Part III of the Town and Country Planning Act 1990.

So the condition wins. And building in reliance on a right the condition has removed is a breach of planning control, not a technicality.

How the condition actually operates

The GPDO grants planning permission for the classes of development set out in Schedule 2. Article 3(4) makes that grant subject to any condition on an express permission that would be contravened by the works.

Nothing needs to be registered separately and no further notice is served. If your decision notice contains the condition, the right is gone for that property from the date of the permission, and it stays gone unless the condition is removed or varied.

Two related mechanisms are often confused with it. An Article 4 direction is made by the council over an area, after a formal procedure, and it withdraws specified classes from every property in that area. A restrictive covenant is a private law obligation between landowners with no planning effect at all. Only the condition and the direction bind the planning system.

Reading the wording carefully

Conditions removing rights come in two shapes, and the difference matters.

The specific version names the classes. Something along the lines of: notwithstanding the provisions of the GPDO 2015, no development within Classes A, B or E of Part 1 of Schedule 2 shall be carried out without planning permission. That is enforceable, and you know exactly what you have lost.

The blanket version removes everything in a Part, or occasionally everything in Schedule 2, with a short reason about protecting the character of the area. National guidance on the use of planning conditions is clear that conditions restricting future permitted development or changes of use will rarely pass the test of necessity, and that they should be used only where the circumstances are unusual. A condition drafted so widely that it is not obvious what it prohibits also sits awkwardly with the precision test.

A third shape turns up on prior approvals and on conversions, where the condition is buried in a schedule of a dozen others and refers to a Class by letter alone. Those are the ones owners miss, because nothing in the wording says permitted development.

Read the reason as well as the condition. A reason that identifies a specific harm on a specific site is much harder to argue with than one that recites a general policy aim. The reason is also where you look first when you want the condition varied.

When a council may lawfully impose one

There are situations where the case is properly made out. The pattern is usually that the permission was only acceptable because of something the permitted development right would undo.

• A dwelling in the Green Belt, where the openness of the site is the reason the scheme was acceptable and unrestricted extensions and outbuildings would erode it.
• A small plot where the private amenity space, parking or drainage was assessed as adequate at the exact size approved and nothing more.
• A site in a conservation area or the setting of a listed building where roof alterations and boundary treatment carry heritage weight.
• A conversion or a new dwelling next to a neighbouring window where an extension permitted under Class A would create an overbearing relationship the council refused to accept at the outset.
• A scheme where surface water drainage was designed to a fixed impermeable area, so a right to lay unlimited hardstanding would defeat it.

Where you are the applicant and you can see one of those arguments coming, address it in the planning statement rather than waiting for the condition. Offering a narrow condition on the one class that matters is a better outcome than receiving a broad one.

Getting a condition removed or narrowed

Three routes, with different costs and different odds.

1. A section 73 application to vary or remove the condition. This is the normal route. The council considers only that condition, and you can propose replacement wording that keeps what the officer was worried about while releasing the rest. Expect eight weeks and a fee.
2. An appeal under section 78 against the condition, within six months of the decision. Weigh this carefully, because the Inspector redetermines the application and the permission itself comes back into play.
3. A planning application for the specific works you want, which sidesteps the argument about the condition altogether. On a single modest extension this is often faster than fighting the principle.

For a section 73, build the case around the reason for the condition. If the reason was drainage capacity, produce the drainage calculation showing the additional hardstanding can be accommodated. If the reason was amenity space, show the space remaining after the proposed extension against the council's own standard. Where the condition covers a conservation area, a short design and access statement explaining the design response does more work than an argument about whether the condition should have been imposed.

There is also the awkward option of arguing the condition is unlawful, on the basis that it fails the necessity or precision tests. That argument belongs in an appeal or in submissions on an enforcement notice, and it needs proper advice. A lawful development certificate will not resolve it for you, because the certificate process asks whether the works are lawful, and if the condition stands they are not.

What happens when you sell, or when a neighbour asks

The condition runs with the land. It binds you, your buyer and everyone after them, and it will appear in the conveyancing search on the permission.

Illustrative example: a self-builder completes a detached house on a former garden plot, granted with a condition removing Part 1 Classes A, B, C and E because the original approval turned on the amount of garden retained. Four years later a buyer's solicitor raises it. The sale proceeds, at a reduced price, because the buyer had planned a garden room. A section 73 application before marketing, with a drawing showing where an outbuilding could sit without affecting the retained garden, would have been the less expensive fix.

One more point about timing. A section 73 application is easier to argue while the officer who imposed the condition is still in post and the file is fresh, and harder once the estate is built out and the council is looking at cumulative effect across a dozen plots. If you intend to challenge a condition, do it early rather than at the point of sale.

The habit that avoids all of this is small. When a decision notice arrives, read every condition, list the ones that restrict future work, and keep that list with the deeds. Most disputes about permitted development rights are really disputes about a document nobody reread.

This is general guidance rather than legal advice. A lawful development certificate is the only formal way to confirm that works are lawful, and you should check the position with your local planning authority or a qualified professional before relying on any rule of thumb about permitted development.
