How to Tell if a Switchboard Upgrade Becomes Common Property

The first five minutes tell you more than the old switchboard does#

A switchboard upgrade in an old brick unit can look like a simple inside-the-unit job right up until you find the meter panel in the hallway, the service fuse in a locked cupboard, or a feeder cable that disappears into a common riser. That’s where the budget blows out and the phone calls start.

If you’re asking, How do you tell early whether a switchboard upgrade in an old brick unit is going to turn into a common-property job instead of just an inside-the-unit job?, the answer is usually not in the board itself. It’s in the path feeding it.

For apartment owners in Melbourne, especially in older blocks around Northcote and Preston, the hard part is not the swap. It’s working out who owns the bit between the street supply and the unit board before anyone starts quoting as if it’s all yours.

The three clues that usually mean it’s not just your unit#

If you see any of these before opening the board, slow down and check ownership. They’re the early warning signs that the job may touch common property.

1. The meter isn’t in the unit.

If the meter is in a shared meter room, hallway cupboard, external meter panel, or a locked bank with other lots, you’re already dealing with shared infrastructure. That does not automatically make the whole job common property, but it means the supply path needs checking.

1. The incoming cable disappears into a shared wall, ceiling, or riser.

In old brick unit wiring, the cable often runs through voids nobody can see without opening up. If it heads into a common riser or service duct, treat it as a likely strata switchboard upgrade until proven otherwise.

1. The service fuse or main isolation point is outside the lot.

If the service protection is in a common meter box or shared panel, the electrician may not be able to isolate or alter the supply without strata access. That’s the point where an inside the unit job becomes a common property job fast.

Key takeaway: If the meter, service fuse, or feeder path is shared, assume you are dealing with a strata switchboard upgrade until you verify otherwise.

What old brick units usually hide#

Old brick units are famous for looking simple on the surface and messy underneath. A lot of them have been altered over the years, often one repair at a time, and nobody has kept clean records.

The usual setup goes like this:

• the meter is in a common bank near the stairs or car park
• the main feed runs through a shared riser or ceiling space
• the switchboard sits inside the unit, sometimes near the front door or laundry
• someone has swapped bits over the years without updating labels or strata records

That’s why How do you tell early whether a switchboard upgrade in an old brick unit is going to turn into a common-property job instead of just an inside-the-unit job? is really a question about tracing ownership, not just wiring.

The parts that usually reveal the boundary#

Look at the:

• meter position
• service fuse or main switch position
• feeder cable route
• point where the cable enters the lot
• location of any shared meter panel or riser

If the meter and service gear are in common property, the board may still be inside the unit, but the upgrade scope can still touch shared equipment. That matters for access, approvals, and who pays.

The stuff electricians misread most often#

The most common mistake is assuming the switchboard location tells you ownership. It doesn’t.

An electrician sees a board inside the unit and quotes it as an inside-the-unit job. Then the job starts, and suddenly the incoming supply is fed from a shared meter panel, the main fuse is in a locked common cupboard, or the feeder needs work in a common ceiling space. Now you need strata approval, access coordination, and sometimes a revised scope.

The other common misread is trusting old labels. In older strata blocks, labels are often:

• faded
• handwritten years ago
• swapped when a previous owner did a patch-up
• wrong because the meter bank was reconfigured
• useless because the unit numbers changed after a renumbering exercise

A label saying “Unit 4” on a panel door does not prove ownership. A meter tag does not prove the cable route. A neat board inside the flat does not prove the supply is private.

What actually helps settle ownership early#

The fastest useful information is usually a mix of documents, labels, and a physical trace. You need all three if the setup is old enough to have been modified.

Start with these documents#

• strata plan or plan of subdivision
• any electrical upgrade assessment or previous electrician’s notes
• building records showing meter locations
• body corporate or owners corporation maintenance records
• old compliance paperwork if the unit has had rewiring or a previous switchboard upgrade

If the strata manager has records of meter relocations, service fuse work, or common riser access, that’s gold. In older Melbourne blocks, especially around inner north suburbs, those records can be patchy. Still worth asking.

Use labels, but don’t trust them alone#

Labels help when they line up with what you can physically see. They mislead when they’re old, generic, or clearly copied from a previous setup.

A useful label usually matches:

• the unit number on the meter
• the physical route of the incoming cable
• the board you can actually isolate
• the current lot boundaries on the strata plan

If those don’t match, stop and verify.

The quickest verification method#

A proper electrical upgrade assessment should include a visual trace from the meter to the board, plus a check of what can be isolated inside the lot without touching shared gear. That often settles the question in one site visit.

If you can’t trace it cleanly, don’t guess. Guessing is how a simple quote becomes a dispute.

The modifications that blur the line between lot and common property#

Older units often have a history of little changes that make the boundary hard to read.

Typical signs include:

• a newer board fitted over older cabling
• mixed cable types, with old cloth or rubber wiring feeding newer breakers
• a meter panel that looks newer than the rest of the common area
• a feeder cable that has been extended or joined in a hidden space
• evidence of past patching around the meter bank or riser entry

That last one matters. If someone has extended the incoming supply or moved the board at some point, the current setup may not reflect the original ownership boundary at all.

This is where How do you tell early whether a switchboard upgrade in an old brick unit is going to turn into a common-property job instead of just an inside-the-unit job? becomes a tracing exercise. Follow the supply, not the assumptions.

When the board is inside the unit but the job still touches strata#

This is the bit people miss.

The board can sit neatly inside the unit and still require strata involvement if:

• the meter is in a common area
• the service fuse is shared
• the feeder runs through a common riser or ceiling
• the electrician needs access to a locked meter room
• the supply needs temporary isolation at common equipment

In that case, the work is often split into two parts:

1. Inside-the-unit work, which the lot owner usually controls
2. Common-property work, which needs owners corporation approval and access

That split is normal. It just needs to be identified before the quote is locked in.

If the electrician is also checking for safety switches and RCDs, this is a good time to sort the whole board properly rather than patching only the obvious fault. A switchboard upgrade should show exactly what is being replaced, what stays, and what depends on strata access.

What decides it when access is shared#

If the meter panel, riser, or service gear is shared, the deciding factor is usually control of the equipment, not where the final board sits.

Ask three blunt questions:

• Who can legally isolate the supply?
• Who controls access to the meter panel or service fuse?
• Does any part of the upgrade require work outside the lot boundary?

If the answer to any of those is “the owners corporation” or “the strata manager”, you are in common-property territory for at least part of the job.

That’s why a good sparky won’t just quote from the front door photo. They’ll check the supply path first. In a place like Preston or Northcote, where plenty of older brick units were built with shared service infrastructure, that saves everyone a mess later.

The trap that stalls jobs halfway through#

The most common reason these jobs stall is simple. Nobody agreed on ownership before the first hole was drilled.

The electrician starts inside the unit, then discovers:

• the service fuse is locked in common property
• the meter bank needs access booked through the strata manager
• the incoming cable has to be replaced through a shared riser
• the quote didn’t allow for after-hours access or extra isolation

Now the job stops while everyone argues about who pays for what.

You avoid that by making the ownership call before pricing. Not after the first fault is found. Not after the board is half stripped. Before.

Key takeaway: The job usually stalls when the quote treated a shared supply path like a private one.

What to do when the boundary is unclear#

If the ownership line is fuzzy, use a simple decision process.

1. Stop and document what you can see#

Take photos of:

• the existing board
• the meter location
• the service fuse
• the cable route if visible
• any labels or tags
• the common area access point

This is the minimum you need for a clean quote and for strata discussion.

2. Quote the known inside-the-unit portion separately#

If the board itself can be replaced without touching shared infrastructure, that part can often be priced as the lot owner’s job. Keep it separate from anything that depends on access to common property.

3. Mark the unknowns as provisional#

If the feeder route, service fuse arrangement, or meter access is unclear, don’t pretend it isn’t. Put the uncertain items in the quote as provisional or subject to inspection of common property. That’s better than underquoting and copping a fight later.

4. Bring in the strata manager early if shared gear is involved#

If the meter room, riser, or service fuse sits outside the lot, the strata manager needs to know before the work is booked. That’s not red tape for the sake of it. It’s how you avoid delays, access issues, and blame-shifting.

5. Push ahead with the lot work only if it stands alone#

If the inside-the-unit portion can be completed safely without touching shared gear, there’s no reason to hold that up while the common-property side is sorted. Just be clear about the boundary in writing.

What a good assessment should tell you before you commit#

A proper electrical upgrade assessment should answer these points before any work starts:

• Is the meter inside the lot or in common property?
• Is the service fuse shared?
• Can the board be isolated from inside the unit?
• Does the feeder run through a common area?
• Will the job need strata access or approvals?
• Is the quote for a lot-only upgrade, a common-property switchboard upgrade, or both?

If the answer sheet is vague, the quote will be vague too.

For owners trying to budget, that’s where the pain starts. For contractors, it’s where margins disappear. For property managers, it’s where everyone starts pointing at the plan and nobody wants the bill.

A plain way to handle it without overcomplicating it#

If you’re standing in an old brick unit and still asking, How do you tell early whether a switchboard upgrade in an old brick unit is going to turn into a common-property job instead of just an inside-the-unit job?, use this rule:

• if the board, meter, and supply path are all inside the lot, it’s probably a private job
• if any part of the supply, metering, or isolation gear is shared, treat it as a strata job for that portion
• if you can’t prove the boundary quickly, quote the known work and mark the rest provisional

That’s the cleanest way to avoid a half-finished job and a messy argument over ownership.

The practical next step#

Before you book the work, get three things sorted: a photo set of the board and meter area, the strata plan or lot boundary details, and a quote that separates lot work from any common-property work. If those three don’t line up, you do not yet have a clean scope.
