Due Diligence and Site Assessment

Structural Inspection

A specialized assessment by a structural engineer evaluating a building's foundation, framing, and load-bearing systems — warranted whenever a general inspection flags something structural.

Definition

A structural inspection is a specialized assessment conducted by a licensed structural engineer to evaluate a building's structural integrity, including foundation, framing, and load-bearing systems. This more detailed and technical assessment goes beyond what a general property inspection covers, and is typically warranted when specific concerns arise or when planning significant building modifications.

When a structural inspection is warranted

A structural inspection becomes particularly important when a general property inspection reveals concerning signs (visible cracking, settlement, or unusual deflection), when planning significant modifications like adding a mezzanine or heavy equipment, or when verifying a building's actual floor load capacity for a specific heavy-use operation.

What to watch for before committing

Licensed structural engineer engagement

Engage a properly licensed structural engineer, not a general property inspector, for this specialized assessment.

Specific concern documentation

If a specific concern prompted the inspection, ensure the engineer specifically addresses and documents findings related to that concern.

Load capacity verification for intended use

If verifying floor load capacity for a specific heavy-use operation, confirm the assessment directly addresses your intended point and uniform loads.

Modification feasibility assessment

For planned modifications like mezzanine additions, ensure the structural inspection specifically evaluates feasibility and any required reinforcement.

Written report and documentation

Obtain a detailed written report documenting findings, methodology, and any recommendations, not just verbal assurance.

Cost and timeline for identified repairs

If issues are identified, get realistic cost and timeline estimates for any recommended structural repairs or reinforcement.

When you need to know this

  • General inspection reveals structural concerns — obtaining specialized expert assessment of flagged issues
  • Planning significant building modifications — verifying structural feasibility for additions like mezzanines
  • Verifying floor load capacity for heavy use — confirming structural capacity matches your specific operational needs
  • Purchasing or leasing an older building — assessing structural condition given age and potential wear

Frequently asked questions

What is a structural inspection? +
A structural inspection is a specialized assessment conducted by a licensed structural engineer to evaluate a building's structural integrity, including foundation, framing, and load-bearing systems.
When do I need a structural inspection versus a general property inspection? +
A structural inspection is warranted when a general inspection reveals concerning signs, when planning significant modifications, or when verifying floor load capacity for a specific heavy-use operation — it's a more specialized, technical assessment.
Who should conduct a structural inspection? +
A licensed structural engineer, not a general property inspector, should conduct this specialized assessment given the technical expertise required.
What triggers the need for a structural inspection? +
Common triggers include visible cracking or settlement noted during a general inspection, plans to add a mezzanine or heavy equipment, or the need to verify floor load capacity for a specific intended use.
