Access Control Permit Requirements in Snohomish County, Washington

Installing access control systems in unincorporated Snohomish County requires understanding both electrical permit requirements and building code compliance for egress doors. Whether you're installing card readers, electronic locks, or enterprise access control systems, this guide covers what contractors and property owners need to know.

Quick Answer: Do You Need a Permit?

Yes, most access control installations require permits. Washington State L&I requires electrical permits for low-voltage work including access control systems. Additionally, installations affecting egress doors must comply with IBC requirements as adopted by Snohomish County and may require building permit review.

• New access control system installations

Even exempt installations must comply with IBC egress requirements and ADA accessibility standards.

Contractor Licensing Requirements

For doors with electromagnetic locks released by motion sensors. Permitted in occupancy groups A, B, E, I-2, M, R-1, and R-2:

• Motion sensor: Must detect occupants approaching and unlock door automatically
• Fail-safe operation: Loss of power to sensor or lock must unlock door
• Manual release button: Must directly interrupt power to lock (independent of access control electronics)
• Button location: 40-48 inches above floor, within 5 feet of secured doors
• Unlock duration: Minimum 30 seconds after manual release activation

Electromagnetically Locked Egress Doors (IBC 1010.1.9.9)

Alternative compliance using door-mounted release hardware. Permitted in occupancy groups A, B, E, M, R-1, and R-2:

• Listed hardware with built-in switch to release magnetic lock immediately
• Obvious method of operation, operable with one hand
• Works under all lighting conditions
• Loss of power to hardware automatically unlocks door

Door Hardware Requirements
