See: http://www.huduser.org/Publications/pdf/smartcodes.pdf) Background In many regions of the country older housing accounts for a substantial part of the housing inventory. In the Northeast almost 30 percent of all housing units in 2000 were originally constructed before 1939. In the Midwest, more than 21 percent of the existing homes were in place before 1939. These units have the potential to continue to provide housing for millions of Americans who might not be able to afford newly constructed, higher priced homes. Unfortunately, many of these older homes need repairs or renovation in order to be made marketable. Further, the local building code requirements often have resulted in inflated rehabilitation costs thereby reducing the affordability of the rehabilitated units. The problem is that building codes for new construction are rarely suited for use in rehabilitation or renovation projects. The provisions of traditional technical building codes are inappropriate for work in existing buildings; they are inappropriate for changing the use-category of an existing building; and they are inappropriate for regulating the task of making an addition to a building. Fortunately, ongoing regulatory reform efforts have resulted in the creation of the International Existing-Building Code (IEBC). This building code addresses many of the impediments to rehabilitation and renovation that were common in previous code iterations. Recent changes to the IEBC have made it an even more valuable tool for rehabilitation projects. The Old Approach Before the recent reforms were enacted, code officials used a formula to determine the acceptability of rehabilitation. Known as the “25-50 percent rule”, the older codes established different rules based on the “cost” of the planned construction relative to the value of the un-rehabilitated structure. Although the wording of the rule varied somewhat in different jurisdictions, generally it stated… If work would not exceed 25 percent of the structure’s present value, then the contractor and building officials could negotiate what work was required to bring the building into compliance with the current local code. For work that would cost between 25 and 50 percent of the value of the existing structure, the contractor would have to meet current building codes for all work being performed. If the planned work exceeded 50 percent, then the contractor would
