Councils require approval
Do I require any council approvals to install an umbrella with a 5m diameter around a poolside? It is an offset, freestanding cantilever-style with 360-degree rotations and will be bolted to a concrete pad
Going back quite a few years, the essential sun protection device in everyone’s backyard was the shade sail. These were available in various shapes and sizes, and used over vehicles, pools and entertainment areas.
At first, council approval was not requested or issued (except for large commercial sails), because they fell outside the standards that triggered the requirement for an approval. In some cases, the application cost more than the sail itself, so why would you bother?
These installations caused a lot of damage and complaints during the first winter that this trend took off.
Problems typically resulted from incorrect post footings being used for the very high posts that were often positioned close to, and sometimes over the boundary.
In a storm, these posts were ripped out of the ground and fell on boundary fences and other property.
Other anchor points included brick walls, the home (wall and roof), and existing patios or pergolas. Often these chosen anchor points were not designed to withstand the imposed wind loads, which particularly damaged fences, masonry walls and roof fascias.
An engineer is required to determine a suitable anchor point (structural building element) and the anchorage type, but they are often not engaged to calculate the design loads.
Once these incidents started being reported, councils insisted on approvals for shade sails and started advising their removal in windy weather. Your large outdoor umbrella is not dissimilar. An engineer would need to design the concrete footing suitable for anchoring the umbrella in a worst-case scenario to ensure it is secure.
They will also determine a suitable distance for the umbrella from the pool structure.
Building work that includes structural work, requires a building permit. Plus, you must check if there are any local planning requirements, depending on the location of the pool.
