Conditions and limitations that defeat permitted development
A condition imposed on a permission years ago can withdraw permitted development rights across a whole estate. Nobody has to tell a purchaser, so the check belongs in the first hour of the job.
Article 3(4) of the General Permitted Development Order 2015 is the provision that quietly ends a lot of schemes. Nothing in the Order permits development that would be contrary to a condition imposed on a planning permission granted otherwise than by the Order. So conditions removing permitted development rights on a permission granted 15 years ago still bite today, they bind whoever owns the land now, and nobody is obliged to tell a purchaser about them.
How a condition displaces a permitted right
The mechanism is simple. Permitted development rights are a grant of planning permission by the Order. Where an earlier express permission carries a condition that the proposed development would breach, article 3(4) withdraws the Order's grant to that extent.
A condition on a housing estate permission stating that no development within Classes A to E of Part 1 shall be carried out without planning permission removes the right to build an extension, an outbuilding, a porch or hard surfacing on every plot covered by it. A condition restricting the hours of use of a commercial unit prevents reliance on any permitted right that would produce a use outside those hours.
The condition does not need to mention the Order by name, but it does need to be clear. Courts have consistently held that permitted development rights are not removed by implication, and that clear language is required to take away a right the Order grants.
Where clear language is used, it works. In Dunnett Investments Ltd v Secretary of State the Court of Appeal held that a condition limiting use to a specified class "and for no other purpose whatsoever" was sufficiently clear to exclude the change of use rights in the Order. A condition that simply names a use class, with nothing more, generally is not.
Limitations distinguished from conditions
A limitation is built into the permission itself rather than imposed on top of it. The description of development in a permission defines what was authorised, and anything outside that description was never permitted at all.
That distinction matters because the two are enforced differently and removed differently. A condition can be varied or removed under section 73. The description of development cannot be changed that way, following the Court of Appeal in Finney v Welsh Ministers, so a limitation inside the description generally needs a fresh application.
Limitations also appear inside the Order itself. Each class in Schedule 2 has its own limits on size, height, position and materials, and a development that breaches one of those is not permitted development at all, regardless of what any earlier permission says. Those limits are the first thing to check, and the detail matters: the depth limits for a Class A rear extension by house type and the volume allowances on roof enlargement both turn on measurements taken from the original dwellinghouse rather than the current one.
Reading a decision notice for hidden restrictions
Most restrictions are found in documents nobody asked for. Work through the planning history rather than the latest decision notice.
- Obtain the full planning history for the site from the authority's register, including outline permissions, reserved matters approvals, section 73 permissions and any prior approvals.
- Read every decision notice in that history rather than just the most recent, because a condition on the original outline permission binds the whole estate.
- Check the approved plans and the description of development on each notice for limitations.
- Obtain any section 106 agreement and read the restrictive covenants in it, which can bar development that planning conditions permit.
- Check the register for Article 4 directions affecting the area.
- Check the title register for private restrictive covenants, which are a different matter entirely.
The last point catches people. A private covenant on the title, often imposed by the original estate developer, is enforceable by whoever has the benefit of it and has nothing to do with planning. Planning permission does not override it. A homeowner can hold a lawful development certificate and still be injuncted by a neighbour under a covenant.
Estate wide conditions on modern housing
Volume housing permissions granted since the mid-2000s very commonly remove Part 1 rights across the whole site, sometimes with different conditions for different phases or house types.
The usual reasons given are the density of the layout, the need to protect amenity space, parking retention, or the appearance of a designed street scene. Whether those reasons still hold 12 years later is a fair question, and it is the question a section 73 application asks.
Conditions removing rights in the interests of biodiversity or drainage are more durable. Where permeable surfacing or private garden space formed part of the drainage or net gain calculations for the estate, an authority is rightly reluctant to release it plot by plot.
Check the phase. Estates are built out over years under multiple reserved matters approvals, and the conditions on phase one are not always the conditions on phase four.
Removing a condition through section 73
An application under section 73 to vary or remove the condition is the direct route. It is determined on the planning merits, so the authority reconsiders whether the restriction remains necessary rather than simply honouring the original decision.
Make the case specific to the plot. A statement showing the proposed extension, its relationship to neighbours, the retained garden area against the authority's standards and the parking retained is far more persuasive than an argument that the condition is outdated in principle. A short Planning Statement doing exactly that is usually all the application needs.
Two practical notes. The application produces a new permission with its own conditions, so read what comes back rather than assuming only the offending condition changed. And the fee for a section 73 on a householder scheme is modest against the cost of an enforcement dispute.
Where the objective is a larger house rather than this particular extension, it is worth checking whether another route avoids the condition altogether. Adding a storey under Class AA sits in Part 1 and will usually be caught by the same condition, but a full planning application for the same result is not.
Enforcement where the condition is breached
Building in breach of a condition is a breach of planning control. The authority can serve a breach of condition notice, against which there is no appeal to the Planning Inspectorate, or an enforcement notice, against which there is.
Immunity periods changed under the Levelling-up and Regeneration Act 2023, so the old four year rule for operational development no longer applies in the way many people remember. Work out the position by reference to the date the breach began and the law in force, rather than by habit.
The commercial consequence usually arrives at sale. A buyer's solicitor requests the planning history, finds the condition, finds the extension, and requires indemnity insurance or a retrospective application. That is a poor time to discover the problem.
Due diligence before design work starts
Build the check into the first hour of every job. Before measuring anything, pull the planning history, read the conditions, check the title and confirm whether an Article 4 direction applies. It takes an afternoon and it prevents a scheme being designed against a right that does not exist.
Where the answer is finely balanced, apply for a lawful development certificate under section 192 of the Town and Country Planning Act 1990. It is the only formal way to confirm that proposed works are lawful, it is decided on the law rather than on planning merits, and it gives the client something a purchaser's solicitor will accept.
For commercial premises the same discipline applies with different classes. Restrictions on hours, servicing, mezzanine floors and external plant regularly defeat rights that would otherwise be available, and the interaction with the Part 7 limits for extending a shop needs checking against the actual decision notice rather than the Order alone.

Frequently asked questions
Can a planning condition remove permitted development rights?
Yes. Article 3(4) of the General Permitted Development Order 2015 means nothing in the Order permits development contrary to a condition imposed on a planning permission granted outside the Order. The condition binds successive owners, and no separate notification is given when land changes hands.
How clearly must a condition be worded to remove rights?
Clearly. Rights granted by the Order are not taken away by implication. In Dunnett Investments the Court of Appeal held that a condition limiting use to a specified class and for no other purpose whatsoever was clear enough to exclude change of use rights, whereas a condition that merely names a use class generally is not.
What is the difference between a condition and a limitation?
A condition is imposed on top of a permission and can be varied or removed under section 73. A limitation is built into the permission, usually through the description of development, and cannot be changed under section 73 following Finney v Welsh Ministers. Each class in Schedule 2 also carries its own internal limits on size, height and position.
Do restrictive covenants affect planning permission?
No, they are separate. A private covenant on the title is enforceable by whoever holds the benefit of it and is unaffected by a planning permission or a lawful development certificate. A homeowner can be entirely lawful in planning terms and still be restrained by a neighbour under a covenant, so check the title as well as the register.
Can I get a condition removing permitted development rights lifted?
Apply under section 73 to vary or remove it. The authority reconsiders whether the restriction remains necessary on the planning merits. Make the case specific to the plot, showing the proposed works, the relationship to neighbours, the garden area retained against the authority's standards and the parking kept.
