Credentials & honors

Imperial Building & Insts LLC is a Spokane Valley general contractor whose record runs through public agencies rather than private homes. Its prevailing-wage filings, from 2018 into 2026, show subcontract work for Stevens County, Lincoln Public Hospital District #3, the City of Ellensburg, Spokane County Purchasing and Cheney School District #360. That spread, from Spokane County out to central Washington, is the most telling thing about how this business operates.

The public-works filings are the clearest picture of the work. Every one lists Imperial as a subcontractor working under a prime contractor, on jobs for counties, a hospital district, a city and a school district. That means the business has worked under prevailing-wage rules and the paperwork that comes with them, across several counties. The state lists Scott Norton and Amy Norton as principals since 2018, and Imperial holds a Washington general contractor registration through L&I, with a general specialty. Imperial mostly works for other contractors rather than directly for homeowners, and its work history is with public owners. It suits a general contractor looking for a registered sub on a school, county or municipal job around Spokane, Spokane Valley or Cheney. A homeowner planning a kitchen remodel or an addition is likely to find better fit with a residential firm that runs its own jobs from start to finish. Spokane's building stock pulls general contractors in two directions. Older neighborhoods near downtown and the South Hill have early-1900s framing, plaster walls and foundations that rarely match modern dimensions, so opening a wall often turns up surprises. Newer subdivisions in Spokane Valley, Liberty Lake and Airway Heights are mostly standard framing and drywall, where work goes more predictably. Public buildings bring their own mix of older masonry and newer steel. When hiring, ask what kinds of buildings a contractor has actually worked in, and match that to yours.
