Local authority permitted development under Part 12

Councils do not need planning permission for everything they build. Part 12 of Schedule 2 to the General Permitted Development Order 2015 gives local authority permitted development rights over small ancillary buildings, works and equipment on land they own or maintain, and over a defined list of street items such as lamp standards, bus shelters, seats, bins and barriers. That is why a new bin store appears in a park, or a set of bollards on a verge, with no notice on a lamppost and no application to read.

The rights are narrow. They are also widely misunderstood, in both directions, by residents who assume the council can do anything and by officers who assume Part 12 covers more than it does.

What Part 12 actually permits

Part 12 has two classes. The first covers the erection, construction, maintenance, improvement or alteration by a local authority of small ancillary buildings, works and equipment, required on land belonging to or maintained by that authority, for the purposes of a function it carries out on that land. The second covers specified public service items: lamp standards, information kiosks, passenger shelters, public shelters and seats, telephone boxes, fire alarms, drinking fountains, refuse bins and baskets, barriers for controlling people and vehicles, and similar structures needed to run a public service.

Three limbs of the first class do the work. The building must be small and ancillary. The land must belong to or be maintained by the authority. And the development must be required for a function the authority exercises on that land. A depot building on a park depot site qualifies. A commercial unit on the same site, let to a third party, does not.

Read the Part's own limits in the Order rather than relying on a summary, because the class carries size restrictions and the drafting is specific. The text on legislation.gov.uk is the one to work from.

Where the right stops and an application starts

The right runs out quickly in practice. It does not cover a new building that is not ancillary to a function on that land, a change of use, anything above the size limits in the class, or development on land the authority neither owns nor maintains.

Nor does it cover development by someone else on council land. If a school, a leisure trust, a parish council or a developer is carrying out the work, Part 12 is not available even where the council owns the freehold, because the class is tied to development by the local authority itself. That distinction matters when a site is leased out.

Highways work is a separate point. Section 55(2)(b) of the Town and Country Planning Act 1990 takes most works carried out by a highway authority on land within the boundaries of a road, for maintaining or improving the road, outside the definition of development altogether. So a resurfacing scheme, a new crossing or a build-out usually needs no permission because it is not development, rather than because Part 12 permits it. The same is true of many statutory undertakers' works under Part 8 and Part 9 and under their own legislation.

Listed buildings, conservation areas and Article 4

Permitted development is permission under the planning Acts. It is not consent under the heritage regime. Works to a listed building that affect its character as a building of special interest still need listed building consent under the Planning (Listed Buildings and Conservation Areas) Act 1990, whoever carries them out, and a council is in exactly the same position as a private owner.

In a conservation area the duty under section 72 of that Act applies to the authority's own decisions, and demolition of most buildings still needs planning permission. An Article 4 direction can also withdraw Part 12 rights for a defined area, which some authorities have done to control street clutter in historic centres.

Protected trees are the other common overlap. Works to a tree covered by a Tree Preservation Order need consent even where the associated building work is permitted, and councils often serve orders on trees in their own parks. If a project involves working near those trees, a tree survey to BS 5837:2012 is the document that establishes root protection areas before anything is dug.

Publicity, consultation and why you never heard about it

Nothing in Part 12 requires public notice. There is no application, so there is no site notice, no neighbour letter, no 21-day consultation period and no committee report. That is the honest answer to the common complaint that a council built something without telling anyone.

Some authorities consult anyway, through ward councillors, a park users group or a parish council, as a matter of local practice rather than obligation. Others publish a schedule of planned works. Neither is a statutory requirement, and the absence of consultation is not by itself a ground of challenge.

If the work matters to you, the practical step is to ask early, in writing, which permission the authority is relying on. The answer is usually one of four things: Part 12, section 55(2)(b), a separate permission already granted, or an application that is about to be made.

Challenging works carried out under Part 12

Start by testing whether the right applies at all. The questions are whether the land belongs to or is maintained by the authority, whether the development is ancillary to a function carried out there, whether it is within the size limits, and whether a heritage consent or tree consent is also needed.

If it does not apply, the works are unauthorised and the authority can be asked to regularise them, although enforcement against itself is a theoretical remedy rather than a practical one. The realistic routes are a formal complaint through the council's own procedure, then the Local Government and Social Care Ombudsman on maladministration, or judicial review in the Planning Court where there is a public law error and the timing allows it. Judicial review is expensive and the window is short.

Where the works affect a listed building or a protected tree without the necessary consent, the position is stronger, because those are criminal offences and the enforcement powers sit with the authority and, for listed buildings, with others too.

Where a council has to apply to itself

For anything outside Part 12 and outside section 55(2)(b), a local planning authority must apply for permission for its own development. The Town and Country Planning General Regulations 1992 set out how. Regulation 3 covers development by the authority on its own land, and a permission granted under it benefits only that authority. Regulation 4 covers development by the authority jointly with someone else, or on land it owns where another party will carry out the work.

Those applications are publicised and consulted on in the ordinary way, and they are usually determined by committee rather than by delegated officers, because of the obvious interest in the decision. The authority still needs the same supporting documents as anyone else, including a Planning Statement and, where the local list requires one, a design and access statement.

Our note on permeable front garden surfaces and Class F shows how tightly a single class can be drafted, and the piece on the curtilage rule for garden outbuildings shows how those limits are measured in practice. The same reading discipline applies to Part 12.

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 under section 191 or 192 of the 1990 Act is the only formal way to confirm that works are lawful.
