Frequently asked questions

• How does the climate affect different fence materials?

  When choosing a fence, you should take into account the climate of the area where you live. For example, in colder climates, consider the frost line and use concrete anchors placed deep enough to support the fence posts. For warmer and wetter climates, you should stay away from most woods because they are susceptible to water damage. Vinyl is the best choice for more temperate regions as it can hold up in damp weather, but it can be damaged by extreme heat. If you live in an area that experiences frequent frigid temperatures, then you may want to stick with more durable materials. Metal, bamboo and specific species of wood are the most resilient materials in colder climates.

• How high can my fence be?

  Boundary walls and fences must be measured from the existing level of the ground that abuts the wall or fence. If the level of the ground on opposite sides of the fence or wall are not equal, the height should be measured from the higher of the two sides. If soil is retained by a boundary wall, the maximum permitted height of the retained soil is 2,1 m. This should be measured from the natural ground level in front of the wall. A balustrade wall not exceeding 1 m in height is permitted above the level of the retained soil.

• Do I need a plan for building a fence?

  For any fences that do not exceed 1.8 m in height you won’t need a plan as they are considered “minor building work”. However, you will still need authorisation by your local authority's building control officer.

• When is it legal to install barbed wire fence?

  You cannot install a barbed wire fence in a residential area or in a commercial area.
