Fencing Contractor Hornsby NSW

Under Hornsby Shire Council's exempt development provisions, side and rear boundary fences up to 1.8 m in most residential zones do not require a DA. Front fences must generally not exceed 1.2 m. Properties within heritage conservation areas, Bushfire Attack Level zones or ridgeline protection areas may need a DA. We check your property's constraints before quoting.

Hornsby Shire contains extensive bushland, and many properties sit within Bushfire Attack Level (BAL) zones. For BAL-12.5 and BAL-19 rated lots, treated timber fencing is permitted but must be constructed with ember-resistant details. For BAL-29 and higher, we recommend Colorbond steel or aluminium fencing, which meets the requirements of AS 3959-2018 Construction of buildings in bushfire-prone areas.

Hornsby's hilly terrain means many blocks have significant falls across the boundary line. We use a combination of stepped Colorbond panels and retaining boards (timber or concrete) to manage the grade change cleanly. For drops greater than 300 mm, we recommend a retaining wall and fence combination, which we can also design and build.

Yes. Under the Dividing Fences Act 1991 (NSW), a fencing notice must be served on your neighbour before any dividing fence work. The notice must describe the proposed work and estimated cost. Your neighbour has 21 days to respond. We can assist you with preparing the fencing notice documentation.

Standard 1.8 m Colorbond fencing in Hornsby costs approximately a quoted rate per metre supply and install. This range reflects variations in site access, slope, soil type and post-hole difficulty. Rocky sandstone in parts of Hornsby Heights can increase excavation costs. We provide transparent, itemised quotes so you know exactly what is included.
