What Is A CL-100 Letter?


If you’re buying or selling a home in Columbia SC and surrounding areas, you will be asked to obtain a CL-100 inspection report ( CL100). This report is commonly referred to as the termite letter.The CL-100 is the official South Carolina Wood infestation report and should include information based on the visual inspection for all wood-destroying insects, fungi and/or moisture issues. The CL-100 inspection should be completed by a qualified, licensed South Carolina home or pest inspectors. The inspection report is valid for 30 days from the day of inspection.

If you’re buying a home or selling a home, you should choose a home inspector to provide the CL-100 letter and the home inspection report.

What’s Included In A Wood Infestation Report?

The wood infestation report is a report of visible infestation and damage by insects ( e.g., termite and beetles) and  decay in accessible areas of the structure, with the inspection for decay fungi limited to the portion of the structure below the level of the first main floor. 

This report is mandatory as a protective measure, banks and lending institutions require that homes be inspected for damage from termites and other wood-destroying organism before you will be loaned money to purchase your dream home.

So, what’s included in this report? The wood infestation report is a two-page document. On the first page you will see basic information about the inspection, such as the address of the property, and answers that address the following questions:

  • Where was the damage found?
  • What caused the damage?
  • Is there any visible evidence of infestation or previous treatment?
  • Are there any obstructions or inaccessible areas which cannot be inspected?
  • Were all the damages reported?
