What is the TIP zone map?
Monday, June 18, 2018
TIP is an acronym that stands for Termite Infestation Probability, and the TIP map divides up the U.S. into zones according to the likelihood of subterranean termites infesting a house. The four zones range from “Very Heavy” to “None to Slight” probability and, since termites are moisture-dependent and do not tolerate severely cold weather, the Southeastern states and California are rated as the highest risk areas for termite infestation.
The map was originally published by the U.S. Forest Service as part of an old termite prevention bulletin, then updated based on newer data in the 1980s. It is significant because the TIP Zone Map is used by VA and some other mortgage lenders to determine if a termite inspection will be required as part of the loan approval process. “Very Heavy” and “Moderate to Heavy” zones require the WDO (Wood Destroying Organism) inspection by the VA. Also, the International Residential Code (IRC) uses the map as a guide for local building officials to determine areas where termite-prevention soil treatment is necessary at the footprint of a new home.
