About Union Seattle Storage Group
Union Seattle Storage Group is a specialty self-storage facility in Seattle, Washington, established in 2008. The site supports climate-controlled storage, business inventory & records, with on-site staff, controlled access, and unit sizes ranging across the most-requested footprints. Renters in this market often choose Union Seattle Storage Group for the combination of climate stability, security posture, and proximity to Seattle's residential and business districts.
The facility tracks closely with the broader Washington specialty-storage profile: indoor units run climate-controlled with HVAC and dehumidification, while outdoor and drive-up bays support oversized goods, vehicles, and trailers. The on-site team is available during business hours for move-in coordination, packing supplies, and unit upgrades, and electronic keypad entry plus video surveillance secure the property outside staffed hours. If you're storing anything sensitive — wine, vehicles, fine art, archival records — request the climate logs and access policies before reserving; this facility will share them on request.
Specialty conditions
Each storage type at Union Seattle Storage Group has its own conditions and operating norms. Climate-controlled and wine-grade units are temperature- and humidity-managed with continuous monitoring. RV and boat bays are sized for full-size rigs and many cruiser-class boats, with shore power and dump-station access available at participating sites. Document and records storage follows industry chain-of-custody norms with logged retrieval. For vehicle and fine-art storage, expect indoor bays with battery tending or museum-grade conditions, respectively. Bring your specs and the facility will confirm fit before move-in.

What renters say
“For client document storage, the chain-of-custody and on-demand retrieval window matters more than price. StoreDash listed three local options that all met our standards. Booked the same week.”
Renee Castillo — Estate planner
“Museum-grade conditions for a fraction of what a commercial art warehouse charges. Their viewing room means we can show pieces to collectors without a full crating cycle.”
Priya Anand — Gallery operations director
“I store backup hard drives, archival prints, and seasonal gear here. Climate is dialed, and the keypad-only access actually feels like the data is safer than at my studio.”
