Credentials & honors

Spokane, Stevens County and Adams County are where Buildingroot Structures LLC works, as a general contractor whose recent record is public work. Between 2023 and 2024 it filed prevailing-wage jobs for the Spokane Department of Transportation, Stevens County and Adams County Fire District #3, usually as a subcontractor to a prime contractor. The business traces back to 2017 under an earlier Buildingroot Structures registration.

The state puts the crew at one to three people, with the owner working on the jobs. The state lists Leonard Ziegler as a principal since 2023. Most of the work comes through general contractors rather than straight from homeowners, and new jobs tend to arrive by referral and repeat business, not advertising. That shape suits a prime contractor who needs a small, prevailing-wage-ready sub for a municipal road or drainage job, or a fire district facility upgrade in eastern Washington. A homeowner planning new-construction framing will likely find a better fit with a residential builder. Whatever the job, get the scope written down before comparing bids. List the exact work, the materials or specs you expect, who pulls the permit, who handles cleanup and disposal, and what happens if hidden damage turns up once walls or ground are opened. Ask each bidder to price the same list so the numbers line up. On a rural Stevens or Adams County site, note access, distance from Spokane and any utility locates in writing, since those details are where quotes for the same project drift apart.
