Laws & Rules

The state Legislature approves laws overseeing manufactured and mobile homes, food trucks, and other mobile or modular structures.

Laws for those areas are located in chapters 43.22 and 43.22A of the Revised Code of Washington (RCW).

2018 Rulemaking – Fee Increase

FAS Rule Development
The Washington State Department of Labor & Industries is proposing fee increases for the Contractor Registration, Elevator, and Factory Assembled Structures (FAS) programs.

This includes:

  • Chapter 296-96 WAC.
  • Chapter 296-150C WAC.
  • Chapter 296-150F WAC.
  • Chapter 296-150I WAC.
  • Chapter 296-150M WAC.
  • Chapter 296-150P WAC.
  • Chapter 296-150R WAC.
  • Chapter 296-150T WAC and,
  • Chapter 296-150V WAC.

The proposed changes would increase fees by the fiscal-growth factor rate of 4.0 percent. This is the maximum increase allowed under the state Office of Financial Management. A fee increase is needed to cover operating expenses for inspections and other program public safety activities.
