Where can I find information about change of use class from C3 to C2?

An application for full planning permission for a change of use is often required when changing from a house (use class C3) to a residential institution (use class C2). This is due to the increased activity which a C2 use would have on the local street area through the addition of visitors, staff and changes to parking.

Common Questions

Do new external steps outside my house need planning permission or building control approval?

Planning permission is not normally required for steps in a garden, however, permission may be required if the steps are part of a larger project such as a raised deck attached to the front of the house.

If the external steps are attached to the house and a roof is constructed, this will become a porch which has different rules attached. Read full details on the planning rules for porches in our common projects section.

Different rules may apply if you live in a designated area such as a conservation area or if the building you live in is listed.

External steps will not normally require building regulations approval unless they are part of the access to the building. If they are then you must ensure that you do not reduce the level of accessibility to the house.

You should contact your local planning authority for further project advice, alternatively, you can apply for a lawful development certificate for confirmation that any changes you make do not require planning permission.

Do I need planning permission or building control approval to change a bathroom to an accessible wetroom for disabled access?

Planning permission is not required for internal changes such as changing a bathroom to an accessible wetroom, however, if you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.

Building regulations approval will likely be required for changes to a make a bathroom accessible, specifically when the change will impact the structure of the room, drainage and electrical systems. It is recommended to have work completed by a member of the competent person scheme.

What is the 10-year rule for planning enforcement?

The failure to obtain planning permission or comply with the details of a permission is commonly known as a 'planning breach'.

A planning breach usually occurs when:

  • A development that requires planning permission is undertaken without the permission being granted - either because the planning application was refused or was never applied for
  • A development that has been given permission subject to conditions breaks one or more of those conditions.

If the breach involves a previously rejected development (or the retrospective application fails) the council can issue an enforcement notice requiring you to put things back as they were.

There are statutory time limits for enforcement, these vary based on when the breach took place.

If the breach took place prior to 25 April 2024
  • Change of use of a building, or part of a building, to use as a single dwelling house - Enforcement action can no longer be taken once the unauthorised use has continued for four years without any enforcement action being taken
  • Operational development relating to building, engineering or mining - Enforcement action can no longer be taken from four years, beginning the date where the operations were substantially completed.
If the breach took place on or after 25 April 2024
  • Change of use of a building, or part of a building, to use as a single dwelling house - Enforcement action can no longer be taken once the unauthorised use has continued for ten years without any enforcement action being taken
  • Operational development relating to building, engineering or mining - Enforcement action can no longer be taken from ten years, beginning the date where the operations were substantially completed.
Other time limits:

There is no time limit for enforcement on breaches of planning control relating to relevant demolition.

For any other breach of planning control, ten years beginning with the date of the breach. This predominantly applies to changes of use.

Do I need planning permission to put up a shed?

Rules governing outbuildings apply to sheds, playhouses, greenhouses and garages as well as other ancillary garden buildings such as swimming pools, ponds, sauna cabins, kennels, enclosures (including tennis courts) and many other kinds of structures for a purpose incidental to the enjoyment of the dwellinghouse.

If you are unsure if your planned building falls into the category of 'outbuildings' or if you are unsure if planning permission is required, please contact your local planning authority.

Outbuildings are considered to be permitted development, not needing planning permission, subject certain limits and conditions.

How can I find out if my land is in a green belt?

The green belt is a specially designated area of countryside protected from most forms of development. It is protected to help stop urban sprawl, preserve the character of existing settlements and encourage development within existing built-up areas.

The government are working on improving access to public land records, allowing you to check certain restrictions on land. You can view their progress here and see whether your land is greenbelt (note: this tool is currently under development).

You should contact your local planning authority to find out if your land is in a green belt area, and any policies or restrictions that may apply as a result.
