When it comes to making the most of your outdoor space, a garden shed can be a gamechanger. These infinitely useful, multi-purpose additions can house garden tools and supplies, keep kids bicycles rust free in the rainy weather, and even double as an outdoor hobby room. 

But before you start envisioning your new storage haven or workshop, you must ask the most important question…Do I need planning permission for a garden shed?
The good news is that many types of garden sheds can be built without planning permission, but there are some important guidelines to keep in mind before you begin. 

Let’s break it down so you can get started on your garden project without any worries!

Do I need planning permission for a garden shed?

Not always…

Here are the key exemptions that allow you to skip the planning permission process and get straight to enjoying your new garden shed:

  • Size limits
  • Height restrictions (including the eaves)
  • Distance from boundaries
  • Open space requirements
  • Use restrictions

Size limits:

You don’t need planning permission if the total floor area of your shed is 25 square metres or less.¹ However, the catch is that this total includes any other similar structures on your property. So, if you already have a shed, garage, or log cabin, the combined total area of all of them must fall below this limit.

Rules for garden shed height:

So, how high can a shed be without planning permission? To avoid planning permission requirements, your garden shed should not be taller than 3 metres in height at its apex. This ensures that your new addition remains within acceptable limits and doesn’t disrupt the overall aesthetic of your neighbourhood. These height restrictions are also in place as a consideration to your neighbours who don’t want their natural light and scenic view overshadowed by excessively tall garden sheds.

Eave height restrictions:

In addition to overall height limits, the eave height (the lower edge of the roof) should not exceed 2.5 metres. This restriction ensures that sheds remain unobtrusive and do not obstruct views or light for neighbouring properties.

Distance from boundaries:

Your new shed must be located at least 2 metres away from any boundary of your property. This rule ensures there is enough space to prevent potential disputes with neighbours.

Open space requirements:

You must also be sure that building your shed doesn’t reduce the open space left in your garden to less than 25 square metres. This stipulation is designed to preserve the character and functionality of residential properties. 

Usage restrictions:

You may not live in your shed or keep animals or livestock in it. If you intend your shed to have an irregular use, you should apply for permission to make sure you are in line with planning permission use case guidelines. 

How big can my shed be without planning permission?

The maximum shed size without planning permission in Ireland is 25 square metres area and 3 metres height.

When do I need shed planning permission – Ireland rules

So, when do you need planning permission for a shed?

The short answer is, when your shed exceeds the size and height restrictions laid out in the Planning and Development Act you will need to seek approval first.² Namely 25 square metres of floor area and 3 metres in height. You’ll need permission if you want to live in your shed or use it to house animals or livestock, or if your property is a listed building in a conservation area. 

While many sheds can be built without needing to first get permission, there are specific circumstances where you will need to get approval before erecting one. 

Here’s a detailed breakdown of when planning permission is required for a garden shed in Ireland:

Listed buildings and conservation areas

If your property is classified as a listed building or is located within a conservation area you will probably need planning permission to build a shed³. These areas have strict regulations to preserve their historical and architectural significance⁴. Any new structure, even something as simple as a small garden shed, could impact the character of the area, so you must consult with your local planning authority before undertaking any work.

Size, height, open space, and boundary restrictions

If your proposed shed is bigger than 25 square metres, higher than 3 metres, or needs to be within 2 metres of the property boundary, you will need permission to build it.

Similarly, if your new shed means the remaining open space is less than 25 square metres, you will need to get approval.

2 storey shed planning permission 

Since a 2 storey shed will exceed the general height restriction of 3 square metres, you will need to get planning permission. 

Existing structures

If you already have other structures on your property like garages or other sheds, the combined area of them along with the new shed must fall under 25 square metres. If adding a new shed pushes you above this threshold you’ll need to get approval.

Specific types of sheds

Certain types of sheds may have different requirements based on their materials and intended use. It’s advisable to check the local regulations as sometimes you may need planning permission regardless of size.

If you are planning to live in your shed or house animals, you’ll need permission even if the structure falls within the exemption limits.

Getting planning permission for sheds of different types

When it comes to building a garden shed, not all structures are created equal. Different types of sheds may have varying requirements for planning permission in Ireland. 

Let’s explore the specific rules for various types of sheds to help you navigate the planning process with ease.

Do you need planning permission for a brick shed?

If you’re considering a brick shed, it’s advisable to consult with your local authority to ensure compliance with all regulations. While there are no limitations on using brick as a material to build, it makes your shed significantly more “permanent” and may need permission if it’s significantly different in looks to the current buildings in your neighbourhood. You will also need to lay a foundation that complies with building regulations.

Do I need planning permission for a steel shed?

Much like a brick shed, a steel shed needs a stable foundation, so even if you’re coming in under the designated size and height restrictions it’s a good idea to ask your local planning authority before beginning to build. 

If the steel shed is going to be used for industrial purposes or to store hazardous materials, additional regulations apply and you will need permission.

Do I need planning permission for a lean-to shed?

So long as your lean to shed complies with the general guidelines, you shouldn’t need special permission. However, since lean-to sheds are attached to another building, it’s essential to ensure that the connection does not violate any structural integrity guidelines or local building codes.

How to apply for planning permission for a shed?

If your shed doesn’t meet the exempted criteria, you will need to get permission. Here’s a step-by-step guide to make the process easier for you.

What documentation do you need for garden shed planning permission?

Typically, your application will need the following documents:

  1. A completed application form
  2. A site map
  3. The design drawings/blueprints
  4. An environmental impact assessment (if needed)
  5. Supporting documents (letters of support from neighbours and photographs of the site for example)

How long does shed planning permission take?

Generally, a straightforward application with all the necessary documentation will take around 8 weeks to process.

If your application is denied, you can appeal the decision with An Bord Pleanala within 4 weeks⁵.

How much does planning permission cost for a shed?

Garden shed application fee€34
Agricultural shed€80 or €1 per m² for buildings exceeding 200m²
Newspaper notice€140
Planning maps€126

** It’s a good idea to check the website of your local authority as they often outline the fees in detail.

Additional expenses:

Depending on the scope and complexity of your build, there may be additional costs.

  • Hiring architects or planning consultants to ensure your application meets the requirements.
  • Depending on your site’s current condition, you may need to budget for ground preparation or levelling if you need a foundation laid first.
  • Environmental assessments if this is a consideration for your shed.
  • Legal fees – if there are objections or appeals.

Consequences of building a shed without planning permission

Constructing a garden shed without getting the right planning permission can have serious consequences. While it may seem tempting to bypass the regulations it’s crucial to understand the repercussions before considering this route.⁶ 

Here are some of the consequences you might face:⁷

Enforcement action

If your shed is deemed to be an unauthorised development, local authorities have the power to take enforcement action against you. This can include issuing a warning notice requiring you to stop building or if you’ve finished already, to take it down. Failure to comply, will escalate the situation to legal action. 

The fines are way more than the cost of applying for the correct permission from the start. If you’re prosecuted in a district court, you face fines of up to €5000 and 6 months imprisonment. In more severe cases, if taken to the circuit court, fines can reach €12,600 with potential imprisonment of 2 years. 

Retention planning permission may be required

If you build a shed without permission and are later found out, you may be required to apply for retention permission. This process is lengthy, expensive, and uncertain, as there is no guarantee your application will be approved after the fact. If denied, you may be forced to dismantle your garden shed.

Impact on property value

Unauthorised builds can have a negative impact on your property value. Potential buyers may be put off by an unpermitted shed, fearing they may be in the firing line for future legal complications or enforcement actions.

Strained community relations

Constructing a shed without permission can strain relationships with neighbours in your community. If your shed disrupts views or light for nearby properties, it could lead to complaints and disputes, complicating your living situation.

Demolition orders

Local authorities may demand that you remove the unauthorised build at your own expense. This is not only time consuming and expensive, but it means all the time you spent building it was wasted too. 

Last thoughts

Whether you’re looking to create a cosy workshop, a storage area for your gardening tools, or an agricultural shed for livestock, knowing when you need planning permission and how to apply can save you from inadvertently landing in hot water with the authorities, so take the time to do it right.

Happy Building!

FAQ

What is the largest shed without planning permission?

The maximum size shed you can build in Ireland without planning permission is 25 square metres. The key component of this limit is that it’s a combined total, meaning you could have two sheds, one of 10 square metres and one of 15 square metres, or three sheds of 8 square metres each, so long as together they don’t exceed 25 square metres.

Can I build a shed next to my neighbours fence in Ireland?

No. You should build it at least 2 metres away from the boundary between your property and theirs.

What are the rules for getting planning permission for sheds on agricultural land?

There is no simple and straightforward set of guidelines for farmers. There are so many factors that come into play when building on farmland. The best advice is to get professional help from someone who understands the local laws and zoning regulations to guide you.⁸

What are the slatted shed planning permission guidelines in Ireland?

Since slatted sheds are used to house animals and effectively get rid of their waste in an underground tank system, you will need to get permission.⁹

A slatted shed that does not house animals can be built without planning permission if it has a floor area of 300 square metres or less. However, if you plan to build multiple agricultural buildings within 100 metres of another, their combined floor area must also be considered. These structures should also be at least 10 metres from any public road and at least 100 metres away from other residential buildings, schools, hospitals, etc… unless written permission has been granted by the occupants.

What are the agricultural shed planning permission guidelines?

The following agricultural builds are exempt from planning permission.¹⁰ However, if you plan to change the use at different times of the year, you may fall foul of planning permission rules. 

TYPELIMIT PER BUILD in m²AGGREGATE TOTAL in m²
Roofed animal housing200300
Pig and poultry housing75100
Roofless cubicles200300
Dry stores, barns, sheds300900

What are the farm shed planning permission guidelines?

A shed that isn’t going to house animals or store effluent, can be built without planning permission provided the floor area is 300 square metres or under. If you build more than one, the total area of all your builds may not exceed 900 square metres.¹¹
