Who’s Responsible For A Blocked Drain In A Strata Property?

Brisbane renters and owners alike, you’re going to want to read this one! Because if you’ve got a blocked drain strata situation on your hands, you’re not only staring at a slowly rising puddle. You’re also wondering who to call. The property manager, perhaps. The body corporate?

Or do you just have to deal with it yourself?

We’ve got two bits of good news for you. First, you’re not alone. And second … we’re here to help!

We know all too well that strata drainage responsibility is one of those topics that somehow manages to be confusing even when it shouldn’t be. So we’ve come up with a straightforward breakdown of who owns what when the water stops moving in a Brisbane strata or apartment building.

First, understand how strata drainage actually works

You all know what we’re talking about when we say strata buildings, right?

• Units
• Townhouses
• Apartment complexes.

They all share drainage infrastructure. There’s pipework running inside your lot (your unit), and then there’s pipework running through common property that serves the whole building.

The basic rule is this:

You’re responsible for what’s inside your lot, and the body corporate is responsible for common property.

Sounds simple in theory. A little less simple when the blocked drainage is sitting somewhere between the two …

What you’re generally responsible for

If the blockage is in a pipe that only services your unit – think your shower drain, kitchen sink waste, or toilet – that’s typically your problem to sort. If you’ve been pouring cooking grease down the sink or flushing wipes (please don’t!), that one’s on you.

Signs it’s likely your responsibility:

• Only your fixtures are affected
• The blockage is at or near a single drain point (e.g. one slow shower)
• A plunger or basic clearing would sort it.

What the body corporate is generally responsible for

Common property drains – the main sewer lines, shared stormwater systems, and pipes that run through walls or under the building serving multiple lots – are body corporate territory.

Signs it might be body corporate territory:

• Multiple units are experiencing drain issues at the same time
• The blockage is in a shared pipe or main line
• Water is backing up through floor drains or external overflow points
• The problem keeps coming back even after you’ve had it cleared.

In Queensland, the Body Corporate and Community Management Act 1997 underpins how this is divided up, and most schemes will have a maintenance plan that outlines shared infrastructure responsibilities. Your body corporate manager should be your first call if you suspect the issue is in common property.

The grey zone (And there’s always a grey zone!)

Here’s where it gets fun. Drain pipes don’t always sit neatly inside or outside your lot boundary. In older Brisbane apartment buildings, especially, pipe routes can be all over the place – running through other lots, under common areas, or through structural elements that blur the line entirely.

If your drain is backing up because tree roots have cracked a pipe that happens to serve just your unit, but runs under the common garden, it gets complicated fast. This is exactly why CCTV drain inspection matters – it shows precisely where the blockage or damage is – which means there’s no arguing about who’s responsible for fixing it.

What about renters?

Renters sit one step further removed from this whole thing. If you’re a tenant with a blocked drain strata Brisbane property issue, your job is to notify your property manager promptly and in writing. Don’t ignore it and don’t try to fix it yourself beyond basic plunging – you don’t want to be blamed for making a pipe situation worse.

Your property manager then needs to work out whether it’s a lot owner issue or a body corporate issue. Either way, it’s not your bill to pay unless you caused the blockage through misuse (see: wipes, grease, foreign objects).

The practical stuff: What to do right now

Regardless of who ends up responsible, here’s what to do when you’ve got block drainage happening in a strata property:

1. Document it.

Photo or video the affected drain(s) before anything changes.

2. Check with neighbours.

If others are affected too, it’s almost certainly body corporate territory.

3. Notify the right people.

Renters contact the property manager. Owners contact the body corporate manager or strata committee.

4. Don’t ignore it.

Blocked drains in apartment buildings can back up fast, especially during heavy rain. Brisbane’s wet season doesn’t wait around.

5. Get a professional inspection.

A CCTV drain inspection will settle the question of where the problem actually sits – which protects you whether you’re the owner, the body corporate, or a renter trying to prove it wasn’t your fault.

Why Brisbane strata drain issues need a specialist

Generic plumbers aren’t always across strata drainage layouts. Brisbane apartment buildings – particularly older ones in suburbs like New Farm, Newmarket, Wilston, and Nundah – can have ageing infrastructure, unusual pipe routes, and shared systems that require proper diagnosis before anyone starts clearing drains.

We carry CCTV camera equipment on every job, which means we can show you exactly where the blockage is and what’s causing it – useful information whether you’re a tenant, a lot owner, or a body corporate rep trying to work out who foots the bill.
