Modular buildings for Seattle and Puget Sound
Material Handling USA supplies factory-built modular buildings to Seattle, Tacoma, Kent, Everett and the rest of Puget Sound. As an authorized dealer for a leading U.S. modular building manufacturer, we quote, coordinate freight and arrange installation.
Washington projects we have published include work for a Spokane contractor and a design firm with Seattle and Spokane offices.
Aerospace manufacturing, the Ports of Seattle and Tacoma, biotech and life sciences, technology and food processing drive demand, with the Kent Valley holding much of the region’s warehouse space. See our in-plant and industrial modular buildings and modular in-plant offices.

- Placement: keep doors out of forklift lanes and add guardrail or bollards where trucks pass (see our forklift protection guide).
- Layout: plan windows toward the floor you supervise; our in-plant office design guide covers sizing and room counts.
Seismic and weather notes for Seattle
Seattle sits in one of the most seismically active regions in the lower 48, with long wet seasons and marine air at port sites. Exterior buildings and in-plant offices with storage roofs or second floors are engineered and anchored for the site’s seismic design.
See the seismic anchorage guide and roofing and weather protection.
- Seismic: plan anchorage early; second floors and storage roofs get their own structural review.
- Marine air: ask about finishes for salt exposure at terminals.
- Rain: slope pads for drainage and confirm roofing details on exterior buildings.
- Permits: modular buildings usually still need a permit, so build plan review time into the schedule.
Permits in Seattle
Permits are usually required for occupied modular buildings, including many interior offices. Check with the Seattle Department of Construction and Inspections for sites in Seattle, or the building department of Tacoma, Kent, Everett or whichever city holds your site, and King, Pierce or Snohomish County for unincorporated areas, before you order. We supply drawings for the submittal; see our permits and code compliance guide.
