Conditions that remove permitted development rights
Article 3 makes permitted development rights subject to any condition on a planning permission, so the condition wins. Applying for the extension itself is usually faster than removing it.
If your planning permission carries a condition removing permitted development rights, you cannot build the extension, outbuilding or porch that the rules would otherwise allow, even though a neighbour three doors down can. Article 3 of the General Permitted Development Order 2015 makes the rights subject to any condition imposed on a planning permission, so the condition wins. The way out is an application to vary or remove it, or an application for the extension itself, and the second is usually quicker.
New build estates carry these conditions more often than older housing. Check the permission before you buy, because the restriction travels with the house.
Why rights are removed by condition
The purpose is to keep control of something the authority was worried about when it granted permission.
On a tight infill plot, the house was approved at a size and position that just worked against the neighbours. Allow a 3 metre rear extension and an outbuilding as of right, and the relationship the officer assessed disappears.
In the Green Belt, incremental additions across an estate of new houses add up to a loss of openness that no single application would have been granted.
In a conservation area or a National Landscape, the appearance of the group matters, and rooflights, cladding and large rear boxes change it.
On a new estate, the layout was consented as a whole, with distances between facades, garden sizes and parking all balanced. The condition protects that balance against forty separate householder projects.
None of those reasons is unreasonable. The question in any particular case is whether the reason applies to your house.
When such a condition is justified
National guidance treats these conditions as exceptional. A condition has to be necessary, relevant to planning, relevant to the development permitted, enforceable, precise and reasonable in all other respects, and a blanket removal of rights struggles on more than one of those tests.
Two faults are common.
Imprecision. A condition saying no development within Schedule 2 of the Order shall be carried out, with no indication of which Parts or Classes are withdrawn or why, is hard to apply and hard to enforce. A condition that names Part 1 Classes A to E, with a reason tied to the plot sizes on the approved layout, is defensible.
Absence of justification. The reason for the condition should appear on the decision notice, and where it does not, the officer's report usually explains it. If neither says anything beyond protecting amenity, that is useful to you on an application to remove.
The condition only withdraws what it says it withdraws. A condition removing Part 1 Class A rights, which cover extensions, leaves Class E outbuildings and Class F hard surfaces intact unless they are named too. Read the words carefully before concluding you can do nothing.
Finding the condition on a new build estate
Estates are granted in layers, and the condition can be in any of them.
- Search the authority's planning register by the estate address or the site name rather than by your house number, which often did not exist when permission was granted.
- Find the outline permission and the reserved matters approval, and read the conditions on both.
- Look for later section 73 permissions, which replace earlier ones and carry their own condition schedules.
- Check any discharge of conditions decisions, which sometimes refine what was originally imposed.
- Check whether an Article 4 direction covers the area, which withdraws rights across a whole area rather than for one permission and is a separate thing entirely.
- Check the title for restrictive covenants, which are private law obligations to the developer or a management company and are enforced in the courts rather than by the council.
That last distinction catches people. A covenant preventing extensions is not a planning matter, and removing the planning condition does not release you from it.
Where the officer's reasoning matters, the case file is worth requesting, and the method in getting consultee responses and the officer's case file applies here too.
Applying to vary or remove it
Two routes exist and they answer different questions.
An application under section 73 of the Town and Country Planning Act 1990 to vary or remove the condition asks the authority to lift the restriction generally. If granted, you get the rights back for future work as well as the project in hand. It is the right route where you expect to do several things over time.
An ordinary householder planning application for the specific extension asks the authority to approve one defined project. It is usually faster to prepare, easier for the officer to assess, and more likely to succeed, because the officer can see exactly what is proposed rather than being asked to give up control.
| Section 73 to remove the condition | Application for the extension | |
|---|---|---|
| What you get | Rights restored for future work | Permission for one project |
| What the officer assesses | Whether control is still needed | A drawing of a specific proposal |
| Determination period | Eight weeks | Eight weeks |
| Appeal right | Yes | Yes, through the householder service where applicable |
For most householders the second route is the sensible one. Fees differ between the two, and some reductions apply, so check planning fee exemptions and reductions before paying.
Evidence that persuades an authority
Whichever route you take, the argument is the same: the harm the condition was imposed to prevent would not happen here.
What helps:
- A measured plan showing the distance from the proposed extension to each boundary and to the nearest neighbouring window, with the approved layout drawing alongside for comparison.
- A section through the boundary showing the 45 degree relationship to the neighbour's nearest habitable window, or whatever test the council's own design guidance uses.
- Photographs showing existing boundary screening, with its height, and whether it has matured since the estate was built.
- Confirmation of the garden area remaining after the extension, measured, against any standard in the local design guidance.
- Written support from the immediately affected neighbours, which carries real weight on an amenity point.
- References to similar extensions already approved on the same estate, by application number, which you can find on the register.
A short Planning Statement setting out the condition, its stated reason, and why the reason does not apply to this proposal gives the officer a recommendation to write. Two pages is enough.
Appealing a refusal
A refusal can be appealed to the Planning Inspectorate. For a householder application the appeal deadline is twelve weeks from the decision, which is much shorter than the six months that applies to most other appeals, so diary it immediately.
Householder appeals run on a short written representations procedure using the standard forms and the questionnaire, with no new evidence allowed after submission. Put everything in at the start, including the photographs and the measured drawings, because you will not get a second chance to add them.
Where the authority has not decided within the statutory period, waiting is sometimes better than appealing, and the considerations are set out in appealing non-determination, and whether to wait.
Expect the inspector to focus on one question: whether the specific proposal causes the harm the condition was designed to prevent. Answer that question and nothing else.
Checking before you buy
Three questions to put to your conveyancer in writing, and keep the answers.
Does the planning permission for this house, or for the estate, remove any permitted development rights, and if so which Parts and Classes.
Is the property in a conservation area, a National Landscape, the Green Belt or an area covered by an Article 4 direction.
Does the title contain restrictive covenants limiting alterations, and who has the benefit of them.
A standard local search answers the designation question and does not always surface the condition, so ask for the decision notice itself. If the agent's particulars mention scope to extend, treat that as marketing rather than advice.
This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it, and remember that a lawful development certificate is the only formal way to confirm that works would be lawful.

Frequently asked questions
Can a planning condition really take away my permitted development rights?
Yes. Article 3 of the General Permitted Development Order 2015 makes the rights subject to conditions imposed on a planning permission, so a condition withdrawing a Class prevents you relying on it. The restriction attaches to the property and passes to each new owner until it is formally varied or removed.
How do I find out whether my house has such a condition?
Search the council's planning register by the estate name or original site address rather than your house number, then read the conditions on the outline permission, the reserved matters approval and any later section 73 permission. Ask your conveyancer for the decision notice itself, because a standard local search does not always surface it.
Is it better to remove the condition or apply for the extension?
For most householders, apply for the extension. The officer can assess a specific drawing rather than being asked to give up control for the future, which makes approval more likely. A section 73 application to remove the condition suits owners who expect to carry out several projects over time.
What is the deadline to appeal a refusal?
For a householder application the appeal must be made within twelve weeks of the decision, which is much shorter than the six months that applies to most other appeals. Householder appeals use a short written procedure with no new evidence allowed after submission, so include every drawing and photograph at the start.
Is a restrictive covenant the same as a planning condition?
No. A covenant is a private obligation in the title, usually to the developer or a management company, enforced through the courts rather than by the council. Removing a planning condition does not release you from a covenant, and complying with a covenant does not give you planning permission.
