In 1928, a small group of domestic mutual insurance companies decided to pool their interests and form an Inspection Bureau to eliminate the need for their company representatives to do building inspections. Thus, in July of 1929, the Pennsylvania Mutual Inspection Bureau was founded by seven companies. This service was limited to eastern Pennsylvania. In 1945, the service area extended into the state of New Jersey.

In the early 1940’s, the Pennsylvania Mutual Inspection Bureau also began offering replacement cost services to assist agents and their clients to establish appropriate replacement cost values of their buildings.

In 1950, the Mutual Inspection Bureau was formed to offer inspection services in Florida, Georgia and other southern states. In January 1958, in the interest of greater efficiency, new by-laws were drawn up, and these two Bureaus were merged into a single unit, the Mutual Inspection Bureau, Inc.

In January 1979, the Mutual Inspection Bureau, Inc. expanded and took over the Eastern Federation. At that time, MIB’s servicing territory was PA, NJ, MD, DE, and DC.

In 1990, the Mutual Inspection Bureau, Inc. moved into its present building located at 2217 Forest Hills Drive, Harrisburg, PA 17112.

Recognizing the need for change in the handling of large volume inspection requests and reports, in 2006, MIB stepped into the computer age with the development of its own web based system, Excel-A-Rater. This enhancement has significantly increased the speed and efficiency of the inspection process.

Over the years, MIB’s Valuation Department has earned an excellent reputation for the provision of detailed replacement cost analyses prepared by certified professionals. Updated revisions of replacement cost value are also offered.

Since its humble beginnings in 1929, MIB has undergone many changes. The current service territory is PA, MD, VA, NJ, NC, SC, DC and DE. The member base has grown from its original seven to over 40 member companies plus their subsidiaries. Non-member companies, insurance agencies and their clients also utilize MIB’s services. We remain a non-profit organization focused on quality and integrity.
