Washington’s tower crane permit law takes effect January 1

Starting January 1, 2026, Washington state will require tower crane permits for all construction work involving tower crane operation, assembly, disassembly, and reconfiguration.

Before issuing permits, Washington Department of Labor & Industries (L&I) will conduct safety conferences to ensure all parties understand the safety requirements and related responsibilities. Prime contractors will be required to follow manufacturers’ instructions for operating, assembling, disassembling, and reconfiguring tower cranes. Additionally, contractors must also immediately correct deficiencies that could affect the crane’s structural integrity or safe operation.

Washington L&I began accepting permit applications on December 5. The department requires 20 working days to process permit applications and requests for permitted activities. More information can be found on the L&I website.
