Buying a strata apartment in Sydney is not the same as buying a freestanding house. You are buying an individual lot, but you are also joining a shared building, shared decision-making structure and ongoing financial system.
That is why strata apartment due diligence should happen before exchange, not after. The contract, strata plan, by-laws, strata report and owners corporation records can all affect how you use the property, what you may need to pay, and what legal risks should be clarified before you sign.
This guide is general information for NSW buyers. It is not legal, financial, building, engineering or tax advice. If you are reviewing a specific contract, speak with a property lawyer before exchange.
Why strata apartments need extra legal checks
In a strata scheme, ownership is split between individual lots and common property. NSW Government guidance explains that when you buy a lot, such as an apartment, you also share ownership of common property with other lot owners.
That shared ownership changes the legal review. A buyer needs to understand the lot itself, the contract, the strata plan, the owners corporation, the by-laws, the levies and any building or management issues recorded for the scheme. If the apartment is not strata but company title, see our guide to company title property in NSW.

What you are buying in a strata scheme
A strata apartment buyer usually owns the inside of an individual lot. Common property may include shared parts of the building or land, such as roofs, external walls, lifts, driveways, gardens, stairwells, pools and services running through common areas.
The strata plan is important because it helps identify lot boundaries, common property and unit entitlement. Unit entitlement can affect a lot owner's voting power and share of levies.
Do not assume that a balcony, courtyard, car space, storage cage or external area is owned in the way it appears during an inspection. The contract, strata plan, title documents and by-laws should be checked carefully.
Review the contract before exchange
The contract is the starting point. A legal review can help a buyer understand the title, plan, inclusions, special conditions, settlement timing, cooling-off position, disclosure documents and any strata-specific material attached to the contract.
NSW Government guidance says the seller must include a copy of the strata plan as part of the contract of sale. A solicitor or conveyancer can also obtain the strata plan through NSW Land Registry Services if it is missing.
Before exchange, buyers should consider whether the contract raises issues about:
- the lot and common property boundaries;
- exclusive use or special privilege rights;
- parking, storage, balconies and courtyards;
- levies, outstanding contributions or proposed special levies;
- special conditions that shift risk to the buyer;
- settlement timing and finance-related conditions;
- strata by-laws and any restrictions on intended use; and
- whether further strata records or building advice should be obtained.

Check the strata report and records
A strata report or records inspection can help a buyer understand the practical history of the building. It is not a guarantee that every issue has been identified, but it can highlight matters that deserve further questions before exchange.
NSW Government guidance says a strata report can include information about finances, insurance, building defects and planned works, safety, legal matters, meeting notes and evidence of disputes.
Records and reports may be relevant to:
- annual general meeting minutes and strata committee minutes;
- administrative and capital works fund balances;
- levy history and proposed levy increases;
- special levies or major works discussions;
- building defects, waterproofing, fire safety or cladding references;
- insurance claims and disputes;
- by-law breaches or resident disputes; and
- strata manager or building manager arrangements.
Public NSW strata search information may also show details such as the strata plan number, registered address, lot information, managing agent details and annual reporting information.
Levies, special levies and capital works funds
Strata levies are ongoing ownership costs. NSW Government guidance explains that levies are set at the annual general meeting and paid into different funds for administration costs, building costs and planned works.
Buyers should look beyond the current quarterly levy amount. A low levy is not always a good sign if the building has limited reserves or major works are expected.
Key questions include:
- what are the current administrative and capital works fund balances?
- is there a 10-year capital works plan?
- are major repairs, remediation works or upgrades being discussed?
- have special levies been raised or proposed?
- are there unpaid levies for the lot?
- does the budget appear consistent with the building's age, size and facilities?
These are legal and transaction-risk questions. A buyer should obtain accounting, financial or building advice where those issues go beyond legal review.
By-laws, renovations and daily use restrictions
By-laws are the scheme rules. They can affect daily life in the apartment as much as the contract does.
NSW Government guidance says by-laws commonly cover pets, parking, noise, smoking and short-term rental accommodation. Buyers should also check rules about renovations, flooring, hard-surface works, air-conditioning, balconies, move-in procedures and use of common property.
For example, if you plan to renovate a kitchen, install new flooring, keep a pet, use a car space in a particular way or lease the property for short-term stays, the by-laws should be reviewed before signing.
By-laws have legal limits. They cannot conflict with existing laws and cannot be harsh, unconscionable or oppressive. However, a buyer should not rely on general assumptions. The specific scheme by-laws matter.
Common property, repairs and building defects
Common property responsibility is one of the most common areas of strata confusion. NSW Government guidance says owners are generally responsible for repairing their own property, while the owners corporation is responsible for repairing common property.
In practice, the answer can depend on the strata plan, by-laws, nature of the defect and whether the affected item is inside the lot, on a boundary, or part of common property.
Before exchange, buyers should look for signs of:
- water ingress, waterproofing or balcony issues;
- fire safety orders or rectification programs;
- cladding, facade or structural remediation discussions;
- major works contracts or proposals;
- insurance disputes or denied claims;
- building defect reports or expert reports mentioned in records; and
- large upcoming expenditure that may affect levies.
A legal review can help identify contractual and records-based issues. It cannot replace a building inspection, engineering advice or other technical assessment where the physical condition of the building is in question.
Off-the-plan strata apartments
Many Sydney strata apartments are bought off the plan. This creates extra timing and disclosure issues because the buyer may sign before the building is complete, before the final registered strata plan exists, or before the apartment can be physically inspected.
NSW Government guidance notes that new strata schemes involve special considerations, including the original owner's role during the initial period and documents to be provided around the first annual general meeting.
Off-the-plan buyers should understand how the contract deals with plan changes, sunset dates, deposits, disclosure material, by-laws, schedule changes, defects processes and settlement after registration.

When to speak with a property lawyer
It is sensible to seek legal advice before exchange if:
- the contract contains unusual special conditions;
- the strata report mentions disputes, defects, remedial works or legal matters;
- there are special levies or significant capital works proposals;
- you need to confirm car space, storage, balcony or exclusive use rights;
- you plan to renovate, keep pets, use short-term letting or rely on parking arrangements;
- the purchase is off the plan;
- you are a first home buyer and need the contract explained clearly; or
- you are unsure whether further strata, building, finance or tax advice is needed.
Legal review is most useful before you are bound. Once contracts are exchanged, options can narrow quickly.
