Demolition and Your Neighbours in Boroondara
Demolition in Boroondara is rarely a solo activity. Blocks in Balwyn, Canterbury and Camberwell often sit close together, older homes were sometimes built to or over the boundary, and shared fences, garage walls and mature trees straddle property lines that nobody has looked at in fifty years.
The neighbour side of a demolition is not simply good manners. Parts of it are legal obligations with formal processes, and getting them wrong is one of the few things that can stop a demolition after it has started.
Protection work: the formal obligation
Victorian building law contains a process for what happens when building or demolition work could affect an adjoining property. If the work may undermine, damage or reduce the support of a neighbouring building or land, the owner has to give the adjoining owner formal notice of proposed protection work.
The adjoining owner can agree, disagree, or ask for more information, and the relevant building surveyor makes the determination. It also triggers requirements around insurance and around a survey of the neighbouring property's condition before work begins.
The important practical point is timing. This process runs before demolition, not during, and it takes time. On a tight Boroondara block where the house being removed is close to or attached to something next door, protection work is likely to apply, and it belongs in the program from the beginning alongside the demolition permit.
Dilapidation surveys
Even where formal protection work notice is not required, a dilapidation survey is worth doing on any block with close neighbours.
It is simply a documented record of the condition of adjoining properties before work starts: photographs and notes covering existing cracks, uneven paths, fence condition, render damage. It usually takes an hour and it is inexpensive.
Its value shows up when a neighbour raises a crack after the demolition. Without a survey the argument is unwinnable in both directions, and the usual outcome is that the demolishing owner pays for something that was already there. With a survey, the question is settled by looking at the photographs. It protects the neighbour equally, which is why most neighbours agree to it readily when it is explained that way.
Shared and boundary walls
Older Boroondara properties throw up two versions of this. The first is a genuinely shared wall between attached dwellings. The second, more common, is a garage or outbuilding built hard on the boundary, where the wall serves both properties in practice even if only one owner built it.
Neither can simply be knocked down. A shared wall usually has to be retained, and the neighbouring side made structurally sound and weatherproof once your building is gone. That means engineering input, and it means the exposed face has to be treated and finished rather than left as raw brickwork open to the weather.
This is work that has to be identified at the quoting stage. A demolition quote that has not accounted for retaining and making good a boundary wall will not survive contact with the site, and heritage-sensitive and partial demolition is a different scope from a straightforward clear.
Fences
Dividing fences are shared property, and the rules about who pays for what are set out in fencing legislation. A fence removed or damaged for demolition access is your responsibility to reinstate.
The practical approach is to agree in advance and in writing: whether the fence comes down, when it goes back, what it is replaced with, and who pays. Most disputes here are not about money but about a neighbour finding their back yard open to a building site with no notice and no timeline for it being closed again. Temporary fencing during the works usually resolves that entirely.
Trees
Boroondara has strong tree protections and a lot of mature vegetation, and trees are the single most common source of neighbour conflict during demolition in this area.
The complications are that root systems cross boundaries, canopies overhang, and a tree wholly on a neighbouring property can still have its structural root zone extending well under your block. Excavation, machine tracking and material stockpiling within that zone can damage a tree you do not own and are not permitted to harm.
Identify every protected and significant tree on and adjacent to the site before work starts, get the protection zones marked and fenced, and where a neighbouring tree is involved, tell the neighbour what protection is being put in place. Protecting significant trees during demolition is far cheaper as a planned measure than as a remediation.
Noise, dust and trucks
These are the day-to-day irritations, and they are governed by permitted working hours as well as by dust suppression obligations.
The single most effective thing an owner can do is tell the neighbours what is happening before it happens. A short note or conversation covering the start date, expected duration, working hours and a contact number for problems prevents the majority of complaints, because most complaints are really about surprise rather than about noise.
Give people a name and number to call. A neighbour who can ring the site supervisor about a truck blocking their driveway will do that. A neighbour with nobody to ring will call the council instead, and a council visit costs you a day.
The sequence worth following
Walk the boundaries before you finalise a quote and note every shared structure, fence and significant tree. Have your building surveyor confirm early whether protection work notice applies, because that determination sets your timeline. Commission a dilapidation survey of adjoining properties. Agree fence arrangements in writing. Then, a week or two out, tell the neighbours the dates and give them a contact.
None of this is expensive relative to a demolition. All of it is dramatically cheaper than a dispute with someone you will be living next to for the next twenty years.
