When preparing for a Development Application (DA)Construction Certificate (CC), or Complying Development Certificate (CDC) in New South Wales (NSW), it's essential to understand how project costs are categorised. Two key categories often misunderstood or combined are Consultant Fees and Other Related Development Costs.

This article provides a clear, accurate, and comprehensive explanation of the differences between these two categories, along with a detailed list of the typical expenses that fall under “Other Related Development Costs” during the planning and building approvals process.

1. Definitions & Key Distinctions

Consultant Fees

These are the costs paid to qualified professionals who play a direct role in designing, assessing, certifying, and coordinating various aspects of your project to ensure it complies with planning and construction regulations.

Common consultants include:

  • Architectural Consultant – Architectural design, DA/CC documentation, consultant coordination
  • Town Planner – Planning advice, Statement of Environmental Effects (SEE)
  • Civil Engineer – Site drainage, driveway/access design, bulk earthworks
  • Structural Engineer – Foundations, slabs, beams, retaining walls, and framing
  • Stormwater / Hydraulic Engineer – On-site detention (OSD), water reuse, stormwater infrastructure
  • Geotechnical Engineer – Soil investigations and foundation reports
  • Land Surveyor – Boundary definition, topographic survey, detail and contour plans
  • BASIX / NatHERS Assessor – Energy and water performance assessment
  • Certifier / PCA (Principal Certifying Authority) – Certification of the CC and construction phase inspections
  • Bushfire Consultant – BAL (Bushfire Attack Level) assessments for bushfire-prone areas
  • Acoustic Consultant – Noise assessments for sensitive uses such as childcare or mixed-use developments
  • Traffic Consultant – Traffic and parking impact assessments
  • Flood or Environmental Consultant – Where applicable due to flood overlays or environmental restrictions

In summaryConsultant Fees are professional service costs essential for preparing, certifying, or supporting your application through the approval process.

Other Related Development Costs

These are non-consultancy expenses incurred during the approvals and pre-construction phase. While they do not involve professional consultancy services directly, they are often mandatory or highly recommended due to legal, environmental, or council-related requirements.

These costs are typically paid to government agencieslegal authorities, or specialist third parties, and not to design consultants.
