Yes, you can, but it depends heavily on your local zoning laws, property lines, and Homeowners Association (HOA) rules. Always consult your local municipality’s "setback" requirements to ensure you are legally far enough away from the property line.
The Boundary Distance
Therefore, you can place the garden shed as close as you want to a boundary (example fence), without the concern of planning permission.
Typically, you should aim for at least 3 feet of space, but this is entirely dependent on local zoning laws. This distance helps with maintenance, ventilation, and access. It also makes learning how to make a shed look nice and keep it looking in good shape easier.
When deciding how close to place your shed next to a fence, consider accessibility. You'll need enough space to move around the shed for maintenance tasks such as painting or repairing the structure. A gap of at least 0.5 to 1 metre is recommended to allow easy access to all sides of the shed.
The main guidelines for shed height compliance are as follows: Distance from boundaries - any shed taller than 2.5 metres (8 feet 2 inches) should be placed at least 2 metres from the boundary line. Smaller sheds can be positioned closer, but they should still consider the impact on neighbouring properties.
The 2.5-metre rule applies to the maximum height of a garden room when it is built within 2 metres of your property boundary. If your garden space is placed within 2 metres of any boundary (e.g., fences, walls, or hedges), the total height must not exceed 2.5m to qualify as permitted development.
Your HOA or local zoning and building regulations will have a say in where you can put your shed. Always check with them first. Many building permits will only allow you to place an accessory structure (their term for a shed or other outbuilding) in the side or rear of your yard.
Gravel or bark can be a quick win for drainage and appearance. Soil or grass may need to be levelled for a path or small structure.
Permitted Development rights often let a home extension reach up to 50 mm from a shared boundary with a neighbour. A bigger project might require more space or a formal Party Wall Notice. Some choose to stay at least three metres away from a fence if they're planning deep foundations.
Ideally your garden shed should have a clear space at least 18" wide on all sides, if possible. This ensures easy access for both installation and future maintenance. In reality this is often not practical and at many sites it is not needed. A reduced clearance is often possible on one or two sides.
Are you allowed to put trellis on top of a 6ft fence? Yes, you can add trellis on top of a 6ft (1.8m) fence, but depending on your area you still may not be able to have it with the fence above 2 metres unless you have planning permission.
As a general rule of thumb, Ottawa by-law requires that there be two (2) feet of clearance from the edge of the roofline of the shed to fences and property lines for all sheds up to 160 square feet.
Provided the summerhouse is less than 2.5m tall and do not infringe the above conditions you can build close to the fence. We recommend leaving about 30cm to allow access for treating the building. It is also highly recommended to talk to your neighbours to let them know what you would like to do.
Outbuildings are considered to be permitted development, not needing planning permission, subject to the following limits and conditions: No outbuilding on land forward of a wall forming the principal elevation.
'An ideal pergola should be around 5ft, or 1.5m away from a fence, for aesthetic purposes. This distance also allows ease in maintaining and constructing the piece. It should also keep things civil with your neighbours as it won't cast shade on their garden. '
Ideally, your shed should sit at least 4-6 inches off the ground. This height is perfect for keeping the base dry and safe from rot and bugs.
Or, to be on the safe side, you can simply position your shed at least 2 metres (6 ft.) or more from the boundary. Here's the easy to remember version: Under 15m² (no sleeping): typically no Building Regs application.
5 common mistakes to avoid when building a shed
As a rule, if a fence is not a boundary fence, it must be built at least two feet inside your property line. The best options for building near a neighbor's existing fence are placing the new one right up against the current one or leaving enough space between the fences for someone to mow.
If your neighbour's pergola is freestanding, open-sided, and within height limits, it's likely permitted. But if it's oversized, enclosed, or fixed directly to your fence, they may be crossing the line—literally and legally. Before making any assumptions, it's worth reviewing the official guidelines.
One of the main motivators for adding a trellis to a fence is garden privacy, but, unfortunately, you have no legal right to privacy in your garden, so without permission, you cannot add a trellis to a neighbour's fence. 'In terms of courtesy steps, talk to your neighbour beforehand, even if the fence is yours.
The biggest roadblocks to effective storage are moisture, pests (like rodents and vermin), and temperature fluctuations and extremes.
Unfortunately, the answer is yes. Rats are agile climbers, capable of scaling brick walls, wooden fences, trellises, drainpipes, trees, and climbing plants. This climbing ability is one of the reasons it's so important to physically block entry points, which we'll cover in more detail in the next section.
Sprinkling cayenne pepper around the fence line can also be an effective deterrent. The sharp scent and irritation discourage dogs from digging. Just be sure to use it sparingly and avoid areas where children might play.
