If you are planning to build a garden shed, you need permission from the local planning commission. You always need to check with the local authorities about garden planning permission. That being said, in most communities, permission is already granted in the building codes for building 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.
When planning a garden shed you may draw your own plans, but it is often inexpensive to purchase plans for a typical garden shed. These plans will give you a materials list and the exact length to cut each board. This can save a lot of time and effort on your part. If you are inexperienced at building, the plans can help you to build a shed that is structurally sound and designed to last for many years.
If you are required to get special permission for building the shed, having plans is an important part of the process. This allows the planners to see exactly what you have in mind, and may make it easier for you to get the approval that is needed.
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.
