When Is Garden Planning Permission Required?
Anytime you are building any permanent structure you need permission from the local authorities. If you are planning a garden structure, you will need to check about garden planning permission. In most communities permission for small structures is granted in the local building codes and you do not even need a building permit for a normal sized garden shed.
Most communities allow building of a garden shed without special permission that is under a certain size. Normally the maximum size allowed without special permission is 80 to 100 square feet. Additionally, there may be height restrictions and building setbacks that must be met.
In addition to the local planning groups, if you live in a subdivision, there may be covenants, conditions or restrictions that limit your ability to build a garden shed. You should have received a copy of these restrictions in a packet when you purchased your property.
You will need plans for a garden shed. If you are able, you may draw your own plans. Pre-made plans are available from several sources. These plans have the advantage of materials lists and cutting guides. Garden shed kits are also available with pre-cut materials. Plans and kits help to build structurally sound garden sheds that can last for many years.
If you need to apply for a building permit for your shed, it is important that you have building plans. It is easier to get the stamp of approval from planners when the see what you are wanting to do and that you have planned well for the building.
Since you must have the approval for the garden shed, you need to check with the local authorities to see if you need a building permit for the shed. This can often be taken care of with a simple phone call or by stopping by the authorities offices.
