Buyer and lease due diligence

A structured checklist for buyers and tenants of land, sheds and warehouses — and how to run it.

Why a structure helps

Due diligence covers title, records, planning, permissions, utilities, environment and the physical site — and different professionals handle each. A single open-issues list keeps it from fragmenting.

The checklist

Title and records

  • Title chain and advocate's opinion
  • Current revenue or estate records; mutations
  • Encumbrances, litigation, stays

Planning and permissions

  • Applicable plan and zone; CLU or licence held, with conditions
  • Approved building plans; completion/occupation certificates
  • Estate-authority permissions for transfer or lease
  • Fire, pollution-control and other consents for the existing use

Utilities and access

  • Recorded access and its width
  • Sanctioned power load and meter details
  • Water source; groundwater permission if extracting
  • Sewer/drainage arrangement

Physical and environmental

  • Survey of boundaries and area
  • Structural condition of buildings (engineer)
  • Flooding, PLPA/forest, heritage and airport-height checks

For tenants specifically

Ask to see the landlord's title and permissions: a lease from someone without the right to lease, or a building without occupation-stage approval, puts your operation at risk.

Running it

  1. Issue a document request list on day one.
  2. Read documents against each other, not one by one.
  3. Grade each open issue: could it stop the deal, change the price, or just need paperwork?
  4. Send each to the right professional and track to closure.
