Commercial Property Inspections & Building Inspections

We are experts in construction and design defects along with property and casualty claims assessment and documentation. Who are you going to trust with your next commercial property inspection?

We have a definite edge over others...

Commercial and multifamily property inspections, and building inspections,  are performed by a professional Civil Engineer (PE) with over 30 years of experience in design, building construction, project management, land development, solving building and construction problems, and real estate due diligence.


It is critical for potential buyers to understand the physical condition of the real estate and structures they intend to purchase.

Property Condition Assessments (PCAs) are performed based on ASTM Standard E2018 – 15, Standard Guide for Property Condition Assessments: Baseline Property Condition Assessment Process. ASTM Standard E2018 – 15 is a guidance document standard for conducting PCAs intended for use on a voluntary basis by parties who desire to obtain a baseline PCA of commercial real estate or building.

This type of commercial property inspection, or building inspection, is intended to assist the potential buyer with their Due Diligence process. It includes:

I. Initial Walk-Through Survey – We conduct an initial baseline Walk-Through Survey of the Property including the developed and improved grounds, building(s) exterior, and building(s) interior. The goal of the Walk-Through Survey is to identify and communicate Physical Deficiencies.

II. Property Condition Report – We prepare a complete. easy-to-understand, written Property Condition Report (PCR) that conveys and documents our observations made during the Walk-Through Survey. The PCR typically includes the following sections:

  1. Executive Summary
  2. Property-Specific & Client Information
  3. Disclaimer, Use & Purpose of Report
  4. Grounds & Exterior
  5. Building Envelope
  6. Foundation
  7. Roof
  8. Plumbing
  9. HVAC
  10. Electrical
  11. Fire Suppression Equipment
  12. Interior Areas
  13. Special Improvements (if any)
  14. Special or Custom Report Sections (if any)
  15. Summary of Observations

ASTM Standard E2018 – 15 recognizes that there are varying levels of property condition assessment, building inspections, and Due Diligence that can be exercised that are both more and less comprehensive than this guide, and that may be appropriate to meet the objectives of client. Consequently, we work closely with the client to collaborate on key aspects of the PCA that may require special attention. This may include documents and records research and analysis, engineer’s cost estimates to repair, refurbish or replace certain components, cost and feasibility studies to make improvements to the property, or similar customized deliverables.

Other, more specific and comprehensive Due Diligence services are also offered.

Note: Property buyer inspections are not offered for residential properties from 1 to 4 units at this time.
