The increase will go into effect on March 16 for 350,000 customers who have either a Texas Family Home Policy or a Next Generation Home Policy.
The rate request was filed last October with the Texas Department of Insurance after the insurer said they had lost $250 million in Texas over the last 3 years.
Regulators with the state had no objection to the increase.
Farmers last raised rates in Texas in 2011 by almost 4 percent.
