A property, be it a home, a condominium, an apartment complex, or a commercial building, is a huge investment. At ABI, we consider the pre-purchase building inspection an opportunity for you to get to know a residential or commercial building before you commit to it. Our primary role in this journey is to provide you with as much information as possible about the building so you can make wise and informed decisions about its purchase and care. 


ABI is an independent and unbiased home inspection company for premium home and commercial building buyers who want a more comprehensive look into the anatomy of the property they are purchasing. ABI combines a registered architect's training and 40+ years of experience in the inspection, architecture and construction industry to provide unparalleled on-site building evaluations, and written reports that both help clients make good decisions about their purchase, and serve as property owner's manuals in the years to come.

ABI also offers expert witness services for personal injury and construction defect cases. Working with both plaintiff and defense attorneys ABI contributes superior technical skills and a deep knowledge of building technology and codes kept sharp and current through continued work in the field. 


Though many parties may be involved with a single real estate transaction, not all of them will share your goals and objectives for the property. Contractors may have one agenda, the seller of the home another, and the real estate agent a third. When you hire a professional building inspector, you expect him or her to look out for your interests alone and deliver an accurate and objective evaluation of the property. However, when faced with pressure from so many different  sides, it is not uncommon for inspectors to misjudge or overlook important points about the property.

Having been fortunate enough to get involved with the building inspection business when it began, ABI has always been able to adhere to a strict moral and ethical code. Regardless of the circumstances surrounding a property's purchase or sale, our inspections and reports are always independent and unbiased. This is why over 90% of our business is generated through referrals from past clients, attorneys, and other professionals who know that ABI's only interests in the purchase of a client's building are the client's own.
