Maintaining Balconies in Strata and Community Titled Properties

Balconies Are Common Property — and They're Exposed

Balconies are one of the few parts of a strata building that sit out in the weather year-round, completely unprotected. Sun, rain, and salt all take their toll, and unlike a roof or a fence, a failing balcony can fall on someone. Active inspection isn't optional — it's the most important safety duty a Management Committee has.

Who Owns the Balcony?

Strata Title

Under Section 25 of the Strata Titles Act, the corporation must administer and maintain the common property. Balconies are common property — the unit holder owns the space inside the balcony if it's designated a unit subsidiary on the strata plan, but the balcony structure itself belongs to the corporation.

Community Strata Plan

For community titled groups where one lot sits above another (a Community Strata Plan), balconies are treated the same way as in strata title. Section 75 of the Community Titles Act requires the corporation to administer, manage, control, and maintain the common property.

Primary Community Plan

Where each lot sits side by side on its own land, the lot owner owns the building on their lot — including any balcony — and is responsible for its maintenance.

How Balconies Are Built

Most balconies fall into one of three structural categories:

• Cantilevered balconies — the deck joists run a significant distance back into the building proper, anchoring the balcony to the structure with no posts at the outer edge. Visually clean but heavily reliant on the integrity of the connection points inside the wall.
• Post-supported balconies — the outer edge of the balcony rests on vertical posts running back to the building or down to ground footings.
• Footing-supported balconies — variations on the above, with the outer support resting on its own dedicated footings.

Knowing which type you're dealing with matters when something starts to fail, because the failure modes are different.

Common Failure Modes

• Weathering — UV, rain, and temperature swings degrade timber and finishes. Repainting and re-sealing on a regular cycle slows this down dramatically.
• Timber rot — fungi develop wherever water settles into joints between two pieces of timber. Most rot starts at connection points, not in the middle of a beam.
• Steel corrosion — bolts, brackets, and reinforcing rods rust. Coastal and seaside environments accelerate this enormously.
• Concrete spalling — the rebar inside concrete rusts, expands, and pushes chunks of concrete off. Once visible from below, the damage is usually well advanced.

Inspecting a Timber Balcony

Walk through this checklist at least once a year, and after any major storm or unusually wet period:

• Identify the timber species. Oregon (Douglas Fir) is unsuitable for external structures — it's a softwood with a broad pink-tinged grain when freshly exposed. If the balcony is built from Oregon, treat it as already at risk.
• Look for compression or deformity in any structural members. Sagging, splayed posts, or visible bowing are warning signs.
• Probe with a screwdriver. Decayed timber feels soft and spongy. Probe at every connection point, every join, and every place where two pieces of timber meet.
• Get underneath. Use a ladder to inspect connection points at the beams from below. Test the brackets and bolts for rust.
• Check the building anchor. Make sure cantilevered joists actually run into the building, and that bolted connections are secure.
• Inspect post bases. Probe for rot at the base of any timber post. Check that posts are anchored into the ground or into a proper footing — not just bolted to the surface of the paving.
• Test handrails and balustrades. They should not be loose, rotting, or unstable. A rickety handrail is a fall waiting to happen.

Inspecting a Concrete Balcony

• Look for signs of deflection. If the balcony slopes or leans, there's a structural problem. Use a long spirit level if you're not sure.
• Examine the underside. Rust stains on exposed steel reinforcing are a sign of serious internal corrosion.
• Check the handrails and balustrades. Same as for timber — they must not be loose, rusting, or rotting.
• Take spalling seriously. If you can see chunks of concrete flaking off — especially with rebar exposed — get a structural engineer to inspect the whole balcony before it gets worse.

If You're Worried About a Balcony

If a balcony shows any of the warning signs above and you're not sure whether it's still safe to use, block access immediately. Don't wait for the structural engineer's report. Physically secure the access doors so the balcony can't be used until a structural engineer or building consultant has assessed it and certified it safe.

The financial cost of inconveniencing residents for a fortnight is trivial compared to the cost of a balcony collapse — for the people on it, for the corporation, and for the manager who knew there was a problem and didn't act.

Best Practice

• Add a balcony walk-through to the corporation's annual maintenance inspection cycle
• Repaint timber and re-seal timber decks on a regular schedule — before visible deterioration sets in
• In coastal locations, accelerate the inspection cycle to twice yearly and use marine-grade fixings on any new work
• Engage a structural engineer for any concern about deflection, spalling, exposed rebar, or rotted structural members — not a general handyman
• Keep the inspection records — they protect the committee and the manager if a defect is later discovered
