Fire suppression and fire sprinkler contractors in Washington are typically required to hold a state contractor license specific to fire protection work. Licensing requirements vary — some jurisdictions additionally require NICET certification for field technicians, and companies that also service fire alarm systems may need a separate fire alarm license. Always verify a contractor's license with Washington's state licensing board before hiring. Listings on this directory marked License Verified have been cross-referenced against the state database.

NFPA 25 is the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. It mandates a schedule of inspections ranging from weekly (water supply for high-rise buildings) to every 5 years (internal pipe inspections). For most commercial buildings, the core requirements include quarterly inspections of control valves and water flow alarms, annual inspection of all sprinkler heads and components, and a formal written inspection report after each visit. Your local Authority Having Jurisdiction (AHJ) may impose requirements beyond the NFPA 25 minimums.
