Key Risks & Red Flags

Commercial property has different risk factors:

  • Vacancy risk: Finding and retaining commercial tenants can be more difficult.
  • Tenant quality: Your investment depends on tenants paying rent.
  • Market cycles: Commercial property values are more sensitive to economic cycles.
  • Compliance costs: Commercial buildings have higher compliance requirements (fire safety, earthquake strengthening, accessibility).
  • Environmental liability: Contamination from previous commercial/industrial use.
  • Lease complexity: Commercial leases are complex legal documents.

Due Diligence Checklist

  • Assess building compliance (earthquake rating, fire safety, accessibility)
  • Check for contamination (especially for industrial/former industrial sites)
  • Review the BWOF (Building Warrant of Fitness) status
  • Obtain a commercial property valuation
  • Check zoning and permitted activities
  • Review any resource consents and compliance obligations
  • Standard checks: LIM report, building inspection, title review

Frequently Asked Questions

What is a BWOF?

A Building Warrant of Fitness (BWOF) is an annual certification that a commercial building's specified safety systems (fire, lifts, etc.) have been inspected and maintained. Building owners must display a current BWOF.

Is commercial property a good investment?

Commercial property can offer higher yields than residential, but comes with higher risk (vacancy, tenant default, compliance costs) and typically requires more capital. It suits experienced investors who can assess these risks.
