State of Washington Improvements for L&I’s Factory Assembled Structures (FAS) Program

June 20, 2023

The Washington State Department of Labor & Industries (L&I) is considering a fee increase to cover operating expenses, including new technology improvements for L&I’s Factory Assembled Structures (FAS) Program.

A fee increase by the fiscal growth factor rate of 6.22 percent is under consideration. At the end of this notice is a list of areas the increase would affect in the Washington Administrative Code.

Why this is happening

FAS staff reviews and inspects about 10,000 alterations to manufactured homes each year. The program also reviews plans for commercial coaches, factory commercial structures, and food trucks. The fee increase will:

  • Keep up with operational costs for the program; and
  • Help fund new technology to improve service. The current FAS system application is outdated and unable to meet program or customer needs.

The agency filed a Pre-proposal Statement of Inquiry (CR-101) on June 6 regarding the fee increase.
