You would probably expect all extensions to require planning permission, but they sometimes don't.

Permitted developments - no planning permission required

Some extensions may be classed as a 'permitted development' and won't require any planning permission at all.

As long as your project complies with all other permitted development criteria, you can generally build:

• for a detached house - the permitted rear extension is 4 metres from the original rear wall of the house
• for all other houses - the permitted rear extension is 3 metres beyond the original rear wall of the house

Permitted developments - prior approval required

Some larger single storey rear extensions might still be classed as a permitted development, and won't require planning permission either, but you must let us know you are building it. This is called 'prior approval, or prior notification' and is a much simpler process than householder planning permission.

As long as your project complies with all other permitted development criteria, you can generally build:

• for a detached house - the permitted rear extension is 8 metres from the original rear wall of the house
• for all other houses - the permitted rear extension is 6 metres beyond the original rear wall of the house.

Read more about costs and how to apply.

Please note: this process is NOT available for any house in a conservation area.

Extensions which aren't a permitted development

Any extension that doesn't fall into either of the above categories, will require a householder planning application.

These might include:

• an extension to the side of your property
• the height of your single-storey extension is more than 4 metres
• a two-storey extension to the rear of your property
• an extension which wraps around the side and back of your property
• an extension which is being added to an existing extension, that would extend your property more than permitted development rules allow.

These are only some examples of common extensions which will require a planning application.

Planning permission is only needed for a new vehicular access onto a classified road, such as those beginning with an A, B or C. Most houses on an estate will not need planning permission.

However, all works on a public highway will need our agreement and you will need to purchase a 'Vehicular Access Pack' which will give you more information about getting a dropped kerb.

This pack explains the council's requirements and the procedure to be followed.

If you are considering installing a new vehicular access you must have sufficient room on your property for a vehicle to be parked without it overhanging the public highway/footway. The parking space will be a minimum length of the vehicle parked straight on to your property. Parking parallel to the footway is not allowed. The minimum length required is 4.8 metres. If you intend to have gates, this distance will need to be longer as gates must open inwards onto your property.

Charges for this pack and associated inspection fees can be found on the Highway charges page.

You can order and pay in one of two ways:

• credit card, debit card or cheque at any Customer Service Centre
• credit card or debit card by calling customer services on (01482) 393939 - select 'Other Services' and then 'Highways'.

Your pack will then be posted out to you.

Please note: all construction costs must be covered by yourself and there will be a further fee for inspections, if the proposal goes ahead. Extra charges may apply if a Traffic Regulation Order is affected, such as removal of parking bay.

Removing trees?

If your proposed work involves the removal of trees, you should first check if the trees are protected by a Tree Preservation Order or protected by virtue of the property being within a Conservation Area. This can be done by contacting us:

For only £60 we can tell you if you will need to apply for planning permission. It's better to be safe than sorry when it comes to planning permission and building control. We know how confusing it can be so we're happy to help and hopefully take the stress out of your building project:

• we provide a cheap and quick service - only £60 (inc. VAT)
• we confirm whether you need to apply for planning permission
• we establish if you need building regulation approval
• you only need to provide basic sketch plans, making sure that dimensions are clearly indicated (in metres, not feet)
• you get a decision from the council normally within 14 days stating whether or not you need to apply for planning or building regulations approval, however please note that due to very high workloads and the limitations of working from home at this present time, it may take longer to respond to you than usual.
• our decision is written proof if planning permission or building regulations were not required, which is useful when selling your home

Check if you need planning permission and building regulation approval

You can also find out if you need planning permission by submitting a formal application known as a 'Lawful Development Certificate' via the Planning Portal website.

However, this option is rarely used in the East Riding, and is not recommended for the following reasons:

• As this is a national procedure fees vary, but a house extension application will cost £103
• This service does not tell you if building regulations apply
• Full plans of the existing and proposed development have to be provided
• Applications can take up to 8 weeks, as the council still has to consult on them
