What can affect your quote?
- Floor area and storeysThe published bands step up with size; a double-storey house takes longer to bring down and produces more material.
- Construction typeFibro and weatherboard come down faster than brick veneer, and full brick or concrete takes the longest to sort and remove.
- AsbestosBonded asbestos removal is quoted from the assessment. Friable asbestos is removed by our Class A licensed partner.
- Access and machineryNarrow frontages, battle-axe blocks and steep sites limit the machine we can bring in, which changes the time on site.
- Pools, slabs and retaining wallsStructures beyond the house are priced as their own items so you can see what each one adds.
- Council, certifier and utility feesApproval and disconnection fees are set by others. They are itemised separately in your written quote.

Council and approvals
Demolition approvals in the Hills District
We prepare and lodge the relevant demolition application. Council boundaries do not always follow our service areas, so we check the council, planning controls and any heritage requirements for your address.
If you already have approval for a new home, check whether it includes demolition. The council or certifier confirms the DA or CDC pathway and conditions. Your quote identifies responsibilities and external fees.
Our Hills District service area spans four council areas: The Hills Shire Council, Hornsby Shire Council, City of Parramatta Council and Blacktown City Council. All four councils publish heritage requirements that affect demolition and flood or bushfire mapping that can change the approval pathway. The Hills Shire Council and Hornsby Shire Council name specific conservation areas.
The Hills Shire Council19 of our suburbs in this region
- Approvals
- The Hills Shire Council suggests first checking whether a project is exempt or needs council approval, and applications can be lodged and tracked online.
- Heritage
- All heritage items and conservation areas are listed in The Hills’ local environmental plan; the Bella Vista Homestead Complex is one example of a conservation area.
- Trees
- Consent is needed to prune more than 10% of a tree, remove any non-exempt tree or substantially change soil levels within 3 metres of a trunk; priority weeds and fruit trees are exempt. The council says unauthorised removal can be fined up to $1,100,000.
- Flood and bushfire
- Bushfire prone land is land that can support a bushfire or is likely to face bushfire attack, and the council’s interactive map shows a property’s classification.
Hornsby Shire Council9 of our suburbs in this region
- Approvals
- Hornsby Shire Council requires a Waste Management Plan for any development creating demolition or construction waste, aiming to reuse or recycle at least 76%. Demolishing a heritage item or a building in a heritage conservation area needs a Heritage Impact Assessment.
- Heritage
- Hornsby has six heritage conservation areas, with owners’ obligations set out in the council’s development control plan. Demolishing a heritage item or a building in a conservation area needs a Heritage Impact Assessment. Named conservation areas include Beecroft/Cheltenham, Hornsby West Side, The Crescent (Pennant Hills), Wahroonga, Wahroonga (North), Barker College.
- Flood and bushfire
- The NSW Rural Fire Service Commissioner certifies Hornsby’s bushfire prone land map. Complying development there needs a Bush Fire Attack Level certificate, and DAs need a bushfire risk assessment or detailed bushfire report.
City of Parramatta Council3 of our suburbs in this region
- Approvals
- City of Parramatta Council’s demolition page describes the Development Application (DA) pathway through the NSW Planning Portal; a Complying Development Certificate may still be available under the state Demolition Code where the property qualifies. Demolishing something originally built as exempt development may itself be exempt if it meets the state criteria, which rule out heritage-listed properties and heritage conservation areas.
- Heritage
- Work on heritage items and properties in heritage conservation areas needs a DA, and the council says it is highly unlikely to allow their demolition. Some minor works can go ahead through a heritage minor works application.
- Trees
- You need the council’s permission to remove any tree or palm five metres or taller, planted trees three metres or taller, and trees on heritage items or in heritage conservation areas. Removal can’t be approved because of a planned development, only on the tree’s own merits.
- Flood and bushfire
- Parramatta maps high, medium and low flood risk precincts. A DA in a flood risk area needs a flood enquiry application as well as a section 10.7 planning certificate, and redevelopment in medium or high risk precincts needs a flood study and modelling.
Blacktown City Council3 of our suburbs in this region
- Approvals
- Blacktown City Council requires all demolition to meet Australian Standard 2601 and SafeWork NSW (formerly WorkCover) requirements. Small structures like sheds, awnings and fences can conditionally come down without approval; anything else needs a DA with a site investigation (including asbestos), work plan, site plan and waste management plan.
- Heritage
- On heritage-listed properties and in heritage conservation areas, the council does not issue tree permits; tree work there needs a DA with an arborist’s assessment.
- Trees
- A permit is needed for trees over 3 metres high and/or with a trunk 200 mm or wider at 1 metre above ground, while routine pruning and deadwood removal are exempt. Applications take up to 28 days after payment, or 48 hours for an extra urgent fee.
- Flood and bushfire
- Blacktown City Council says some parts of the city are bushfire prone, and its maps can be viewed at the council’s Information Centre.
