State of Iowa, IDNR Time of Transfer Inspection

Iowa's Time of Transfer septic system inspection law (SF261) was passed by the Iowa legislature in April of 2008 and took effect July 1, 2009. The new law requires that every home/building served by a septic system have that septic system inspected prior to the sale or deed transfer for the home/building. The purpose of the law is to eliminate sub-standard or polluting septic systems.   For information concerning Time of Transfer, go to the Iowa Department of Natural Resources web site (click here).
