What this class covers

ANZSIC class 3019 classifies Australian businesses primarily engaged in the construction of residential buildings that are not freestanding houses. This includes managing, organising, or physically carrying out the building work. The core activity involves creating new structures or significantly altering existing ones through additions, renovations, or structural modifications. This classification is used by government agencies like the Australian Bureau of Statistics for economic data collection, and by businesses for accurate reporting on registration forms, insurance applications, and industry analysis.

Typical businesses operating within this class include:

  • A construction company specialising in building new apartment complexes
  • A builder focused on constructing rows of terrace houses or duplexes
  • A renovation contractor undertaking major structural alterations to existing flats
  • A project management firm organising the construction of a new residential high-rise development
  • A company that builds semi-detached housing estates

Primary activities in plain English

Businesses in this class primarily engage in:

  • Constructing apartment buildings and residential units within multi-level complexes
  • Building duplex houses (two dwellings sharing a common wall)
  • Constructing flats and units in low-rise or medium-rise buildings
  • Building high-rise residential towers with multiple dwelling units
  • Performing renovations, alterations, or additions to existing residential buildings that aren't freestanding houses
  • Constructing semi-detached houses (pairs of houses sharing one common wall)

Practical guidance

When registering your business or completing official documentation, use ANZSIC class 3019 if your primary activity matches the description. The corresponding Business Industry Code (BIC) 30190 should be used on your ABN registration and business tax returns. This ensures accurate classification for statistical purposes and may affect your eligibility for industry-specific grants or programs.

For workers' compensation insurance, construction businesses typically fall under specific risk categories based on the nature of work performed. Ensure you accurately describe your activities to insurers, as premiums can vary significantly between different types of construction work. Keep detailed records of your projects, as some government reporting may require breakdowns between new construction versus renovation work.

If your business engages in multiple activities across different ANZSIC classes, you should classify based on your main revenue-generating activity. The Australian Bureau of Statistics provides that businesses should be classified according to their primary activity, which is the activity that contributes most to value added.
