What is a two-lot strata scheme?
A two-lot strata scheme is a strata plan with only two lots — usually a duplex, dual occupancy or pair of villas. What that means legally, how it differs from a bigger scheme, what the 2026 "small strata scheme" changes do, and what the two owners actually have to do.
If you've been told your duplex is "in strata" and you're not sure what that means, this is the page. Two-lot, 2 lot, duplex strata, small strata scheme — they all describe the same thing.
The plain definition
A strata scheme is a way of dividing one parcel of land into separately owned "lots" plus shared "common property". When a builder puts two homes on one block and sells them on separate titles, they register a strata plan with two lots. Each home is a lot; the land, and usually the roof, slab, external walls and any shared driveway or fence, are common property.
The two owners together are the owners corporation — the legal body that owns the common property and carries the obligations under the Strata Schemes Management Act 2015 (NSW). There's no third party; it's just the two of you.
How to tell if you're in one
- Your rates notice, insurance certificate or contract of sale shows a strata plan number: SP followed by digits.
- Your title describes the property as "Lot 1 in Strata Plan 12345" rather than "Lot 12 in Deposited Plan …".
- Not every duplex is strata. Some are Torrens-title (each half on its own DP lot, no owners corporation) and some are community title. If your title says DP not SP, none of this applies to you.
What makes two-lot schemes different
Legally, a two-lot scheme has always been an owners corporation like any other — meetings, committee, levies, records. In practice almost none of them operate that way, which is exactly the gap the 2026 reforms address.
The new "small strata scheme" (s 7A) — a scheme with two lots and no committee — will not need annual general meetings or office-bearers. Every decision is a written resolution both owners sign. From 1 October 2026, two-lot schemes also stop lodging the annual Strata Hub report.
What does not change: the building must be insured in the owners corporation's name for full replacement value with $20 million public liability; common property must be repaired; a strata roll and records must be kept; and a Section 184 certificate must be provided when a lot is sold.
The five things the two of you actually have to do
- Know your strata plan number and hold a copy of the registered plan and by-laws.
- Insure the building correctly — right name, right sum, $20m liability, renewed every year.
- Agree each year, in writing, on what the scheme will spend and how it's split (by unit entitlement, s 83(2)).
- Keep a strata roll: both owners' names, notice addresses, contact details, any mortgagee.
- Write down and both sign every shared decision, and keep the file where both can reach it.
If that's more admin than you want, that's what Duplex Strata does for $395 + GST a year — without ever holding your money.
Is "2 lot strata" the same as "two-lot strata" and "duplex strata"?
Yes. They're the same thing in everyday use. "Small strata scheme" is the new legal term for a two-lot scheme with no committee once s 7A commences.
Can a two-lot scheme be two detached houses?
Yes — a strata plan can cover two separate buildings on one block. Detached two-lot schemes have an extra option: the owners can resolve in writing not to insure jointly and each insure their own building (s 160(4)).
Do we have to have a strata manager?
No. The Act doesn't require a two-lot scheme to appoint one. See our guide on whether you need a strata manager for a duplex.
What's a unit entitlement?
A number on the strata plan for each lot that sets its share of costs and voting. Most duplexes are equal (say 50/50) but not always — check the plan.
- 1 October 2026: two-lot schemes stop lodging the annual Strata Hub report (NSW Fair Trading, "Changes to strata laws").
- Small strata scheme rules (no meetings, decisions by written resolution of both owners, new s 7A): in a Bill that has passed the Legislative Assembly and is before the Legislative Council. They start on a date to be proclaimed. Until then, where the law still requires a meeting we hold a short online one for you at no extra cost.
- Unchanged: the duty to insure the building for full replacement value in the owners corporation's name, to keep common property in repair, to keep a strata roll and records, and to provide a Section 184 certificate when a lot is sold.
No meetings, no commissions, no money handled. Both owners sign online.
