Strata survey costs in Sydney range from $5,000 to $25,000+ depending on building type, number of lots, complexity of common property, and how “clean” the as-built outcome is compared to the approved plans. A simple 2-lot strata (typical duplex) often costs $5,000-$8,000.
A 4–6 unit townhouse development can be $8,000-$15,000. Larger apartment buildings (10+ units) can be $15,000-$25,000+ or more.
What’s Included in Strata Survey Costs?
Strata survey costs typically include:
- Building measurement and floor plan preparation
- Defining lot boundaries and common property
- Preparing the Strata Plan (SP) for NSW LRS
- Unit entitlement calculations and schedules
- Coordination with certifiers/council for subdivision certificate requirements
- Plan lodgement support for NSW Land Registry Services (LRS) registration
Strata isn’t just “drawing floor plans”. The survey must reflect the as-built building and meet NSW LRS examination standards.
Why Strata Surveys Cost More Than Torrens
Strata surveys are usually more expensive than Torrens because they require detailed internal/external measurement of the building, interpretation of lot boundaries (often defined to wall faces), and accurate delineation of common property.
As a comparison point:
- 2-lot Torrens title survey work is often simpler where no common property is created
- 2-lot strata (duplex) commonly costs $5,000-$8,000 for survey work
Legislation and Documentation (NSW)
Strata plans are prepared and registered under NSW strata legislation (learn more about strata vs Torrens), including the Strata Schemes Development Act 2015. Depending on the project, the strata outcome may also need easements/restrictions created by a Section 88B instrument under the Conveyancing Act 1919 (e.g., for drainage, access, or services).
When Do You Need a Strata Survey?
You need a strata survey when creating separate titles for units, apartments, townhouses, or duplexes where there is any shared land or facilities (driveways, gardens, lobbies). If the dwellings share any land, strata is usually required rather than Torrens.
How Long Does a Strata Survey Take?
A strata survey typically takes 4–8 weeks (and overall timing is covered in our subdivision timeline guide) from initial measure to plan completion, but timeframes depend heavily on construction progress and documentation readiness. The building must be substantially complete before final measurements can be taken.
After certification, registration with NSW LRS commonly takes a further 2–4 weeks after lodgement (subject to examination queues and requisitions).
Common Issues That Add Cost (And How to Avoid Them)
Strata costs can increase if:
- As-built differs materially from approved drawings (requires extra measurement and coordination)
- Common property boundaries are unclear (storage cages, car spaces, courtyards)
- Access to all areas is not available at measurement time
- Documentation (architectural plans) is incomplete or inconsistent
Practical tip: schedule measurement when the builder can provide safe, clear access to all lots and common areas, and ensure the latest architectural set is available.
Different Strata Outcomes (Building vs Lot, Common Property Details)
Even within “strata”, the documentation requirements can differ depending on the development type:
- Small duplex strata: often simpler, but shared driveways and service routes still need careful definition
- Townhouse strata: more lots, more common property detail, and more opportunity for as-built variation
- Apartments: complex common property (lobbies, corridors, plant rooms) and more detailed measurement requirements
Authority Fees and Other Costs to Budget For
In addition to the survey fee, you may also encounter:
- NSW LRS lodgement and registration charges
- Subdivision certificate fees (council or certifier)
- Solicitor/conveyancer fees for instruments and coordination
- Potential costs to resolve requisitions if NSW LRS requests changes
How to Keep Your Strata Survey Efficient
- Provide the latest architectural drawings and any changes made during construction
- Ensure safe access to all lots, balconies, courtyards, car spaces, and common areas on measurement day
- Confirm early whether any easements/restrictions will be required via Section 88B
Timing: When to Engage Your Surveyor in the Build Process
For the best outcome, involve your surveyor early—ideally at the design or pre-DA stage—so strata implications can be considered in the site layout. Common timing milestones:
- Pre-DA: discuss lot layout, common property, and likely documentation needs
- During construction: preliminary floor plan checks if significant variations arise
- Post-construction: final measurement once the building is substantially complete
- Post-certification: lodgement with NSW LRS for registration
Leaving strata considerations to the end often results in more measurement visits, documentation rework, and delays—especially if the as-built outcome differs significantly from the approved plans.
FAQ
How much does a duplex strata survey cost in Sydney?
Typically $5,000-$8,000 for the survey work, depending on design complexity and documentation.
Do I need the building finished before the strata survey?
Generally the building must be substantially complete so the survey reflects the final constructed outcome.
What is unit entitlement and why does it matter?
Unit entitlement affects voting power and levies in the strata scheme. It’s part of the strata documentation and must be prepared carefully.
Is NSW LRS registration included in the price?
Survey fees typically cover plan preparation and lodgement support. NSW LRS charges and other authority fees may be separate—confirm when quoting—or contact us for a Sydney strata survey quote.
Can strata be used for a small townhouse project?
Yes. Strata is commonly used for 2–6 townhouse developments in Sydney, particularly where there are shared driveways or shared services.
