How Big Can a Shed Be Without Planning Permission?

Diving straight into the heart of the matter, many of you might be pondering, "How big can a shed be without planning permission?" Well, the quick answer is up to 120 square feet in many areas, but there's a bit more to it than just square footage.

As seasoned experts in the world of shed-building kits, we've navigated the complexities of local regulations and zoning laws to bring you a comprehensive guide.

This article is designed to unfold the nuances of building a shed within legal bounds, ensuring you're well-informed and ready to embark on your shed-building journey without the need for planning permission.

What this article covers:

How Big Can a Shed Be Without Planning Permission?

After putting it to the test in various backyards and gardens, we've found that the largest shed without permit is around 120 square feet. This size limit seems to be a sweet spot for many local authorities, allowing homeowners to add a functional structure without overstepping regulatory boundaries.

A 10x12 or an 8x15 shed translates into a practical yet spacious area, perfect for storing your gardening tools, setting up a cozy workshop, or even creating a peaceful backyard retreat.


It's a size that fits well in most gardens without dominating the landscape, ensuring your outdoor space remains balanced and inviting.

What Is Planning Permission Exactly?

When we talk about planning permission, we're referring to the formal nod of approval from your local council or planning authority for construction projects.

This process is in place to maintain the aesthetic harmony and safety standards of neighborhoods, ensuring that new structures don't obstruct views, reduce privacy, or disrupt the local ecosystem.

It's essentially a check-and-balance system that keeps urban and rural development in line with community standards and regulations.

Obtaining planning permission means your project has been reviewed and meets the necessary criteria, giving you the green light to proceed without fear of future legal or regulatory complications.

It's a crucial step for larger projects, but for smaller sheds within the 120-square-foot guideline, you might just skip this step and dive straight into your building plans.

Why Is It Important to Get a Permit?

At first glance, bypassing the shed building permit process might appear as a clever shortcut, saving you both time and the hassle of paperwork. However, this path can quickly turn bumpy, leading to unforeseen challenges that could have been easily avoided.

Building permits act as a seal of approval from your local authorities, signifying that your shed not only aligns with the aesthetic and structural standards of your community but also adheres to safety regulations.

If you're asking yourself is it legal to build a shed on your property, a permit will allow you to do so. Getting a permit will also clear up questions such as how many sheds can you have on your property.

This is particularly crucial in areas prone to specific environmental challenges, such as high winds or heavy snowfall, where the structural integrity of outdoor buildings is paramount.

Moreover, obtaining a permit ensures that your shed is positioned in a manner that respects zoning laws, safeguarding against disputes with neighbors or the local council. In essence, the permit process is there to protect you, your investment, and the well-being of your community.

What Happens If You Don't Get A Permit?

The immediate consequences might include hefty fines that can quickly escalate, turning what was once a budget-friendly project into a costly ordeal. In more severe cases, you might be ordered to dismantle your newly built shed, a disheartening outcome that wastes both your efforts and resources.

Furthermore, the absence of a permit can become a significant stumbling block if you decide to sell your property. Prospective buyers, upon learning of unpermitted structures, might reconsider their purchase, or worse, demand a lower price, devaluing your property.

In our experience, the risks associated with skipping the permit process are substantial, making it a gamble that's best avoided for the sake of your peace of mind and financial well-being.

How to Get Planning Permission

  1. Check Local Regulations: Start by consulting your local planning authority's website or office. Regulations can vary widely, even within the same country.
  2. Submit Your Plans: You'll likely need to provide detailed plans of your proposed shed, showing dimensions, materials, and location on your property.
  3. Consider Neighbors: Inform your neighbors about your plans. Their support can smooth the process, especially if they have concerns about your shed impacting their property.
  4. Wait For Approval: Once submitted, there's often a waiting period for review and approval. Use this time to refine your shed plans or start gathering materials.
