Plumbing in a condo: the shut-off, the strata and the schedule

The Panther Brief
One useful email a month — seasonal maintenance, real costs, and what to do before you call. No noise. Double opt-in.

Condo plumbing work is frequently simpler than the equivalent job in a house — smaller runs, more accessible, fewer surprises behind the walls.

Everything surrounding it is harder. The building, not the pipe, is what determines how a condo job goes.

The riser, and why it changes everything

A building's water supply runs vertically through risers, with branches to each suite. Anything that touches the riser — not just the suite's own branch — requires the building's water to be shut down.

That means the property manager, notice to residents, a scheduled window, and often a cost the building charges. It cannot be arranged at short notice and it cannot be arranged by you and a plumber alone.

The practical consequence: the first question on any condo job is whether it needs a building shut-down. If it does, the schedule is set by the building rather than by the work.

Some suites have their own isolation valves, which means the suite's water can be shut off without involving the building. That is a large convenience and it is worth knowing whether yours has them — before an emergency, not during one.

If your suite does not have them, having them installed during other work is one of the most useful small upgrades available to a condo owner.

The strata process

Most stratas require approval for work affecting plumbing, and many require it for anything involving contractors on site. Expect to provide details of the work, evidence that contractors are licensed and insured, and to agree to conditions about hours, elevator use and access.

Approval takes time — sometimes a council meeting cycle. Start it early.

The bylaws also usually govern working hours, which affects how many days a job takes. A job that would be one long day in a house may be two shorter days in a building that permits work only between certain hours.

Getting things in and out

This is the most consistently underestimated part of condo work.

A hot water tank has to come out of a hallway closet, along a corridor, into a service elevator, and out of the building — and a new one has to come the other way. Service elevator bookings, protective padding, loading bay access, and sometimes restrictions on which hours moves are permitted all apply.

For a common job with an uncommon complication, this is it: the plumbing might take an hour and the logistics take the day.

What is yours and what is the building's

The division between suite property and common property is set by the strata's own documents, and it varies. Generally the fixtures and the pipes within the suite are the owner's and the risers and mains are the building's — but where exactly the line falls is a question for your strata, and it determines who pays.

It matters most after a leak. A leak that originates in your suite and damages a neighbour's is a different conversation from one originating in common property, and both are different from one where the source is disputed.

Read your strata's insurance and bylaws before you need to. Knowing the deductible arrangement for water damage in your building is worth an hour of reading.

Leaks in a stack of homes

The particular anxiety of condo living is that a leak is rarely only yours. Water goes down, and a failure in your suite reaches suites below.

This is why the shut-off question matters so much, why suite isolation valves are worth having, and why an appliance hose or a toilet supply that would be a nuisance in a house is a bigger event in a building.

If you are in a condo and have never checked your washing machine hoses or your toilet supply lines, that is the cheapest risk reduction available to you.

For renovations

Layout changes are more constrained than in a house — drains and vents are where they are, and moving them may not be possible within the suite. Establish what can move before designing around it.

Sound transmission matters more, because your plumbing runs through walls shared with neighbours.

Working with us

Tell us the building, the suite, whether you have suite isolation valves if you know, and what the strata's requirements are. If a building shut-down is needed we will tell you early, because that is the item that sets the schedule.

FAQ

Frequently asked questions

Can I move the toilet in my bathroom renovation?

Sometimes. It depends on drain fall and floor construction — on a concrete slab or in a condo it is often the constraint that decides your layout. Ask before planning around it.

Can I put a sink in a kitchen island?

Usually in a house with accessible space below for the drain and venting. On a slab or in a condo it may not be feasible, so establish it before finalising the layout.

Do I need a permit for bathroom renovation plumbing?

Generally yes where fixtures are moved or lines altered. Like-for-like replacement in the same position often does not. Unpermitted renovation work surfaces at resale.

Will you install fixtures I bought myself?

Yes. We warrant our installation; the fixture's own warranty stays with the manufacturer. Worth knowing that the difference between a cheap tap and a good one is mostly the cartridge, which is the part that fails.

When should I choose my fixtures?

Before the rough-in, not after. Wall-mounted taps, wall-hung toilets and freestanding tub fillers all need specific rough-in work, and choosing late is the most common sequencing mistake in bathroom renovations.
