Electrical & Safety Requirements for Automated Gate Systems

Installing an automated gate isn’t just about convenience—it’s about safety, compliance, and long-term reliability. In Washington State, an electrical permit and inspection from the Department of Labor & Industries (LNI) is required for any gate operator installation; although some cities like Bellevue choose to inspect themselves. Additionally, state entrapment laws mandate proper safety measures, including photo eyes, safety loops, and obstruction sensors to prevent accidents.


For gated properties, a separate pedestrian gate is also required to ensure safe access without forcing people to walk through an automated vehicle entrance. These regulations aren’t optional—they’re in place to protect lives and ensure your system operates legally and safely.


At Coho Construction, we handle all permitting, electrical work, and inspections in-house, ensuring your gate system is installed correctly, meets all safety codes, and operates seamlessly. Cutting corners isn’t an option when it comes to security and compliance—this must be done right and right changes based on where you live.

 Sliding Gates – Reliable, Powerful & Built to Last

Sliding gates are the go-to choice for heavy-duty security and smooth operation. Designed to handle heavy loads with ease, they require a track, motor base, and durable wheels or a cantilever system for seamless movement. Our top pick for automation is the LiftMaster CSL24UL, paired with a metal-wood gate combo for the perfect balance of strength, style, and longevity.

Swing Gates – Classic, Secure & Custom-Built

Swing gates offer timeless functionality with smooth automation. Our expert team ensures proper control box mounting for clean, secure installations that protect your system from the elements. We take a creative approach to every project, designing swing gates that seamlessly integrate with your property while prioritizing reliability, safety, and ease of use.

They cared about family and wellbeing rather than just a sale. They are good local people that actually care about you and your project. They helped find other services to finish the job as well. Great estimates, program and communication. ​
