Fencing across Blue Mountains City Council

What we install in Blue Mountains

• Colorbond fencing – new boundary fences and replacements in 1.5 m to 2.4 m heights, any Colorbond colour, either sheet profile
• Timber fencing – treated pine paling, lapped and lap-and-cap on galvanised steel posts
• Retaining walls under fences – treated pine or aluminium sleeper walls built directly under the new fence where levels differ
• Fence and gate repairs – leaning posts, storm damage, insurance repairs and gates that will not latch

Ground, access and local conditions

Sandstone ridges with shallow soil in places – post holes sometimes need coring – and bushfire-prone land on the edges of most villages.

• On bushfire-prone lots steel fencing and posts are the sensible choice; Colorbond does not add fuel load the way timber does.
• Tree roots and rock are common on the ridge blocks – we allow for coring and stepped fences in the quote.
• Front fences are usually low and open to keep the leafy streetscape; heritage areas in Leura, Blackheath and Katoomba have specific controls.

Fence rules in Blue Mountains City Council

Under the NSW exempt development rules a boundary fence behind the building line can be up to 1.8 m high without approval on most residential lots. Blue Mountains City Council has extensive heritage conservation areas and bushfire mapping that can change what is exempt – confirm before building. Pool barriers must meet AS 1926.1-2012 regardless of council. Read our NSW pool fencing guide, and confirm anything about your own block with Blue Mountains council.
