When renovating or extending your home, one of the questions you might ask is, "Do I need planning permission for an attached garage?" The answer isn't always straightforward and depends on several factors. Let's delve into when planning permission is required, and when it's not.
Before we proceed, it's essential to understand that the rules and regulations regarding planning permission can vary depending on your location, primarily governed by local councils and planning authorities. Therefore, while this article aims to provide a general guide, it's always a good idea to check your local planning office for specific advice tailored to your situation.
Understanding Permitted Development Rights
In many cases, you won't need planning permission for an attached garage due to 'permitted development' rights. These are a set of rules that allow you to carry out certain building projects without needing planning permission. However, these rights are not absolute and come with size restrictions and specific conditions.
It's crucial to note that permitted development rights are not granted automatically; they come with the title of your property. If you own the freehold or leasehold with more than a year left on the lease, you should have these rights. However, these rights can be removed, for instance, if a property is listed or located in a designated area like a conservation area or an Area of Outstanding Natural Beauty.
Size Restrictions for Garage Conversions or Extensions
When considering an attached garage, the primary factor to check is the size. The new garage, or the extension to your existing one, should not exceed 50% of the size of the original property. This is measured by the "original floor area" of your house, excluding garages and sheds.
For instance, if your house had an original floor area of 200m², you could build an additional 100m² without needing planning permission. However, you should also consider that any previous extensions or additions are included in this 50% limit, not just the original property size.
Conditions for Permitted Development
Besides the size restrictions, there are other conditions attached to permitted development rights. For example, the new garage should not be higher than the highest part of your existing house. Moreover, any extension should be set back at least 2 meters from the boundary of your property if your house is terraced or semi-detached.
Additionally, these rights do not apply to properties that have been significantly extended or altered through planning permission in the past, as the original property size may have changed. Always consult your original planning permission documents to be sure.
When Planning Permission is Required
Despite your best efforts to comply with permitted development rights, there may be instances where you still need planning permission for an attached garage. Here are some scenarios to consider.
Firstly, if your property is located in a designated area, such as a conservation area, an Area of Outstanding Natural Beauty, or a National Park, you may need to seek planning permission even for permitted development projects.
Change of Use
If you're planning to change the use of your garage from its current purpose (e.g., parking a vehicle) to another use (e.g., a home gym, workspace, or studio), it's considered a 'change of use' and may require planning permission. This is because it could have an impact on your neighbors' amenities and may need separate consideration from the council.
Moreover, if you live in a flat or apartment, change of use for a garage often requires permission, as the garage may be part of the building's common areas.
Previous Extensions or Alterations
If your property has had significant extensions or alterations through planning permission in the past, your permitted development rights may have been affected. Always double-check any conditions attached to previous permissions to ensure you don't fall foul of any restrictions.
A general rule of thumb is that if your proposed work does not conform to the conditions of your current permitted development rights, or you're unsure whether it does, it's safer to apply for planning permission to avoid any potential issues down the line.
In concluding, whether or not you need planning permission for an attached garage heavily depends on the specifics of your property and the nature of the project. Though it's always tempting to assume that an extension or conversion will fall under permitted development rights, it's crucial to err on the side of caution and check with your local planning office if you're unsure. They can provide you with tailored advice and help ensure a smooth, stress-free building project.
