Notice of  Potential Safety Hazard
From the U.S. Department of Housing and Urban Development

All property managers need to be aware of lawsuits that have been initiated against various manufacturers of hardboard siding products installed on many structures built during the last two decades.  Many of these suits have been settled and property owners may be entitled to cash recoveries amounting to thousands of dollars per building. 

The covered materials are hardboard siding products manufactured by Georgia Pacific, Louisiana-Pacific, Cladwood, Masonite, and several others.  Eligible properties are generally those built between 1980 and 1998.  In some instances, property owners may also recover for money expended on repair and replacement of covered siding products.  The amount of the recovery depends on the amount of eligible siding products used on the property, the age of the building, the current condition of the hardboard siding, the particular style of siding, and the average cost of labor and materials in the geographic vicinity of the property.  For owners with major sidings problems, the awards run anywhere from $3000 to $50,000 per building.

For those who do not feel able to handle the claim on your own, there are several companies that will do the work and file it for you for a percent of the recovery.  They can be found on the Internet.
