Quick Answer
A survey plan on an ACT property title defines your lot boundaries, easements, and building envelopes. In the Australian Capital Territory, every residential block sits on a Crown lease—so the plan number on your title links to conditions that restrict what you can build, subdivide, or alter. Ordering a title search survey plan before exchange lets you verify boundaries, identify restrictive covenants, and check whether the lease conditions match your intended use.
What a Survey Plan Shows on an ACT Property Title
In the ACT, land titles reference a plan number—typically a deposited plan or unit plan—registered in official property records. This plan is the graphical reference that defines:
- Lot boundaries and dimensions
- Easements (drainage, right of way, services)
- Building envelopes and set-back lines
- Common property areas (for unit plans)
- Notations of restrictive covenants
The plan number printed on your title is not decorative. It is the primary link to the spatial and legal framework that governs what exists on the block and what can exist there in the future.
Key Risks Hidden in ACT Survey Plans
Crown Lease Conditions and Boundaries
Every ACT residential block is held under a Crown lease (also called a state lease). The lease document specifies the permitted use, the lease term, and any development conditions. When you order a title search survey plan, cross-check the lease purpose against your intended use. A lease limited to "single residential dwelling" blocks subdivision or dual occupancy. The boundary dimensions on the survey plan must also match the physical fences—discrepancies can signal encroachments or lost boundary pegs that cost thousands to resolve.
Unit Plans and Common Property
If you are buying a townhouse or apartment, the title will reference a unit plan rather than a standard deposited plan. The unit plan shows your unit boundaries, utility lots, and common property. Check:
- Whether your car space is a utility lot or part of common property
- The exact unit boundaries—some unit plans include internal walls; others define boundaries at the median line
- Whether common property areas (driveways, gardens, roof) impose maintenance obligations you have not budgeted for
Restrictive Covenants
Restrictive covenants registered on the plan limit what owners can do. In newer ACT estates, covenants may mandate specific building materials, roof colours, fence styles, or minimum construction timeframes. Older blocks may carry covenants restricting building height or prohibiting certain structures. These covenants run with the land—they bind every future owner regardless of when they were first registered. The survey plan notation is your early warning. If a covenant exists, order the full instrument text to read the exact restrictions before you commit.
Lease Variations
A Crown lease can be varied after initial registration. Lease variations might change the permitted use, add development conditions, or extend the lease term. The current title will show whether a variation has been registered, but the survey plan itself may still reference the original layout. Always check the title for registered variations and compare them against the plan. A lease variation allowing higher density might explain why a neighbouring block looks different from what the original plan suggests.
Planning Certificate Cross-Check
A planning certificate tells you the zoning and any planning overlays that apply. Cross-referencing the planning certificate against the survey plan and Crown lease is essential because:
- The zone may permit uses that the Crown lease prohibits
- Planning overlays (heritage, bushfire, tree protection) may impose conditions not shown on the survey plan
- Development approval history may have altered site constraints
You need all three documents—survey plan, Crown lease, and planning certificate—to form a complete picture.
What to Order and When
| Document | What It Reveals | When to Order |
|---|---|---|
| Current Title / State Lease Search | Crown lease purpose, term, variations, registered interests | Before making an offer |
| Survey Plan (Deposited or Unit) | Lot boundaries, easements, building envelopes, common property | Before exchange |
| Planning Certificate | Zoning, overlays, development conditions | Before exchange, alongside title search |
| Restrictive Covenant Instrument | Exact wording and obligations of registered covenants | If covenants appear on the plan or title |
A Current Title / State Lease search through TitleFinder is $74.50 AUD and gives you the lease purpose, term, encumbrances, and any registered variations in one document.
Buyer's Checklist: ACT Survey Plan Review
- Verify the plan number on the title matches the plan you receive
- Confirm lot dimensions match the physical boundaries on-site
- Identify every easement on the plan and understand who benefits
- Check for restrictive covenants—order the full instrument if any appear
- Read the Crown lease purpose clause and confirm it covers your intended use
- Look for registered lease variations and compare against the original terms
- For unit plans, check unit boundaries, utility lots, and common property obligations
- Order a planning certificate and cross-check zoning and overlays against the plan
- If the block is on a new estate, check developer covenants and design guidelines
- If anything does not line up, get professional advice before proceeding
Frequently Asked Questions
How do I find the survey plan number on my ACT title?
The plan number appears in the property description section of the title, usually formatted as "Lot X Block Y DP CCCC" or "Unit X UP CCCC." Use this number when ordering a title search survey plan through TitleFinder.
Can a Crown lease purpose be changed after purchase?
Yes, through a lease variation. This requires application and approval through official channels. It is not automatic, and there is no guarantee of success. Check the existing lease purpose before you buy—do not assume you can vary it later.
What is the difference between a deposited plan and a unit plan in the ACT?
A deposited plan defines standard residential or commercial lots with their boundaries and easements. A unit plan defines individual units within a multi-unit complex, plus common property and utility lots. The risks differ: unit plans involve body corporate obligations and shared infrastructure that deposited plans do not.
