What Are Sub-Stratum Rights?

  • Sub-stratum rights pertain to the ownership or use of land below the surface level, separate from surface or air rights.
  • These rights are typically utilised for underground developments like:
  • Tunnels (e.g., subways or roadways).
  • Basements in commercial or residential properties.
  • Mining operations.
  • Underground utilities or storage facilities.
  • Sub-stratum rights can be leased, sold, or assigned independently of surface property rights.

For valuation requirements involving property purchased before completion, AC Valuers also provides Off the plan valuations.

Legal and Regulatory Considerations

  • Ownership of Sub-Stratum Space: In many jurisdictions, the ownership of subterranean rights is tied to the surface property unless explicitly separated by law or contract.
  • Compulsory Acquisition: Governments may acquire sub-stratum rights for public purposes (e.g., transportation or utilities) and require valuations to determine compensation.
  • Easements and Licenses: Sub-stratum spaces may be subject to easements, licenses, or other agreements that impact their valuation.
  • Environmental Regulations: Restrictions on resource extraction or underground developments can affect value.
