The Secretary of the Interior's Standards for Rehabilitation provide a list of ten guidelines that must be met when rehabilitating a historic property for its new, modern use. Following these Standards ensures that the historic character of the property is maintained but that it will be safe and comfortable for its current inhabitants. There is a wealth of guidance available for the interpretation of these Standards. Every Part 2 that is submitted to the Louisiana Division of Historic Preservation is reviewed for conformance with these Standards. 

In Louisiana, we see a number of the same Standards issues time and time again. When planning your rehabilitation project, make sure to keep the following in mind:

  • Spray foam insulation is rarely approved as an appropriate insulation treatment.
  • Historic windows should be retained and repaired, rather then replaced.
  • The use of a replacement siding material on the facade is not approved.
  • Sand blasting and other forms of abrasive cleaning are rarely, if ever, approved.
  • Patchy plaster finishes are not approved. Historic plaster over brick, even fireplaces, must be retained.
  • The first rooms in a shotgun-style house must remain unaltered.
  • Sealers applied to masonry must be breathable and have a matte finish.
