🏡 So You Bought a Duplex… 🏡
(With a Shared Wall Dividing Both Lots)
Welcome to strata living — even if it’s “just two of you.”
If your property is part of a 2-lot strata scheme (duplex), you are automatically part of an Owners Corporation (OC) under NSW strata law.
Even if you and your neighbour get along perfectly.
Even if you’ve “always just split things 50/50.”
Even if you don’t have meetings.
The legislation still applies.

✅ OWNERS CORPORATION COMPLIANCE CHECKLIST
(NSW – Strata Schemes Management Act 2015)
📋 1. Records & Sale Compliance
Your Owners Corporation must have:
· A properly maintained strata roll
· Accurate levy records
· AGM minutes (kept for 7 years minimum)
· Up-to-date financial statements
· A current 10-year Capital Works Plan
· Insurance records available
· Section 184 Certificate issued correctly on sale
If you’re selling, levies and any special levies must be correctly disclosed.
🏢 2. Capital Works Fund
Even in a 2-lot scheme, you must:
· Maintain a Capital Works Fund (unless formally exempt)
· Have a 10-year plan (reviewed every 5 years)
· Strike levies properly at an AGM
Informal arrangements are not compliant.
💰 3. Insurance (Critical in Duplexes)
The OC must:
· Insure the building for full replacement value
· Hold $20 million public liability insurance
· Obtain a building valuation at least every 5 years
· Ensure the policy is current at settlement
Important for duplexes:
· The dividing wall is usually common property
· The full building envelope must be insured
· “We each insure our half” is often unlawful
🔥 4. Fire & Safety
The OC must ensure:
· Fire separation between lots is intact
· No unauthorised penetrations in the dividing wall
· Smoke alarms are compliant
· Any essential fire measures maintained
The dividing wall fire rating is critical.
🛠 5. Maintenance Obligations (Section 106)
The Owners Corporation must maintain:
· The dividing wall (if common property)
· Roof structure
· External walls
· Structural elements
· Common plumbing and drainage
· Shared services
Failure to maintain exposes the OC to damages claims.
📜 6. By-Laws & Alterations
Check for:
· Registered by-laws
· No informal side agreements
· No unauthorised structural changes
· Air-conditioning penetrations
· Roof penetrations
· Decks or pergolas
· Fence responsibility clarity
🧾 7. Levies
Levies must:
· Be struck at a general meeting
· Follow unit entitlements
· Be formally recorded
“No need for levies — we just split it” is not compliant.
📐 8. Boundary & Wall Clarity
In duplexes this is often misunderstood:
· Is the dividing wall common property?
· Has either lot altered structural elements?
· Are fencing arrangements lawful?
· Are boundaries clearly defined in the strata plan?
·
⚠ Common Risks in 2-Lot Schemes
Non-compliance commonly includes:
· No Capital Works Fund
· No building valuation
· No formal AGMs
· Underinsured buildings
· Informal cost-sharing arrangements
· Unregistered by-law changes
Even if both owners agree — these are still breaches.
🎯 Before You Sell (or Buy)
You should confirm:
1. Current building insurance sum insured
2. Date of last valuation
3. Capital Works Fund status
4. Any unpaid levies
5. Dividing wall classification
6. Any special levies determined pre-contract
