Community Strata Divisions in Adelaide
Understanding Community Strata Divisions
Community Strata Divisions are most commonly associated with multi-storey buildings, apartment complexes and mixed-use developments where lots sit above or below each other. Unlike traditional land divisions where boundaries are measured and marked on the ground, Community Strata boundaries are defined by the physical structure itself.
This means the individual lot boundaries follow the walls, floors, ceilings and structural components of the building. In most cases, a plan sheet is created for each level of the development, clearly depicting all lots, common areas and service locations.
Because the boundaries rely on the finished construction, a Community Strata Division cannot be finalised until the building is complete, structurally sound and ready for survey.
When Are Community Strata Divisions Used?
A Community Strata Division can be created for a broad range of residential and commercial developments, including:
- Apartments
- Multi-level townhouses
- Commercial buildings with multiple floors
- Mixed-use developments
- Converted buildings
- Small developments with as few as two lots
- Large-scale complexes with dozens or hundreds of lots
Whether your project involves two levels or twenty, a Community Strata scheme provides a structured, legally compliant way to define lot ownership and allocate common property

How Community Strata Boundaries Are Defined
Under South Australian legislation, the structural components of a building—such as:
- External walls
- Internal load-bearing walls
- Floors and ceilings
- Roof structures
- Columns and beams
are generally defined as Common Property owned collectively by the Community Corporation.
Individual lot boundaries are then determined by the interior surfaces of these structural components, meaning:
- Owners maintain what’s inside their lot
- The Corporation is responsible for the building’s external structural integrity
This arrangement provides clarity around maintenance responsibilities, insurance requirements, and future building upgrades.

Why Community Strata Divisions Are Important
A properly prepared and registered Community Strata scheme ensures:
- Clear and Legal Ownership Boundaries
Each lot owner knows exactly what they own and what is shared.
- Defined Common Property Areas
Lobbies, lifts, stairwells, shared services and structural components are clearly allocated.
- Simplified Building Management
The scheme establishes a Community Corporation with clearly defined responsibilities.
- Smooth Buying and Selling Process
Buyers, lenders, agents and conveyancers all rely on accurate, up-to-date strata documentation.
- Compliance With SA Legislation
Professional surveying ensures your development meets all state requirements and can be lodged with the relevant authorities.
