Strata Conversion Building Certifiers

Strata conversion is the process of converting an existing building from a single title to a strata scheme, creating individually ownable lots within the building. This is commonly done for existing apartment buildings, townhouse complexes, and mixed-use buildings that were originally built as a single entity but are to be sold as individual units. The building certification required for strata conversion involves assessing the existing building against current NCC requirements for the relevant building classification and verifying that the building meets the minimum standards for strata subdivision.

The strata conversion process is often more complex than strata subdivision of a new building because the existing building may not meet current NCC standards. Buildings constructed under earlier building codes may lack adequate fire separation between proposed lots, may not have sufficient accessibility provisions, and may have building systems (such as electrical, plumbing, and fire safety systems) that need to be upgraded or reconfigured to serve individual lots independently. The building certifier must assess these issues and determine what upgrade work is required before the strata conversion can proceed.

Fire safety is typically the most significant compliance area for strata conversions. Adequate fire separation between proposed lots must be established, which may require upgrading walls, floors, and ceilings to achieve the required fire resistance levels. Fire detection and alarm systems must cover each lot independently, and emergency egress routes must be maintained and compliant with current standards. For older buildings, achieving fire safety compliance can involve substantial construction work, and the certifier's early assessment of fire safety requirements is essential for planning the conversion budget accurately.

The building certifier works closely with the registered surveyor who prepares the strata plan. The certifier must verify that the physical construction accurately reflects the proposed lot boundaries, that common property areas comply with relevant standards, and that each lot has the required services connections and access. Any discrepancies between the strata plan and the physical building must be resolved before the certifier can issue the strata subdivision certificate. This may involve either amending the strata plan or carrying out building work to match the proposed boundaries.

Strata conversion certification costs vary significantly based on the age and condition of the building, the number of lots being created, and the extent of upgrade work required. Simple conversions of relatively modern buildings that largely comply with current standards might cost $5,000 to $15,000 for the certification component. Conversions of older buildings requiring significant fire safety, accessibility, and building fabric upgrades can cost $20,000 to $50,000 or more. A feasibility assessment by an experienced certifier before committing to a strata conversion project is a wise investment, as it identifies the likely compliance costs and helps determine whether the conversion is commercially viable.
