Building Partners NW is a general contractor that builds homes and prepares the ground they sit on. It works out of Greenacres, in the Spokane Valley, for homeowners planning new construction, garages, porches or accessibility changes to an existing house. The state insures its crew for excavation, underground utility lines, foundations and flatwork alongside framing and finish carpentry, so site work and the build itself can stay with one outfit.

The company says it handles custom home building, retirement homes, land development and project management, including budget tracking and final cleanup. It also lists smaller jobs: insulation, driveway and roof work, backup generator installation, heated bathroom floors, wheelchair accessible modifications and snow load roof design. The workers'-comp classes back up the range, covering ditch work, landscaping, masonry, drywall, painting and remodeling. The work traces to a predecessor business, MH5 Construction, dating to 2017. The state lists Mark Folsom and Heidi Folsom as principals since 2025, and the crew runs in the four-to-six range. Building Partners NW suits a homeowner around Greenacres who wants one contractor to take a lot from dirt to finished house, or to adapt a home for aging in place. A crew this size, working mostly through referrals and repeat clients, fits residential builds better than large commercial developments. Homeowners who need only a standalone plumbing or electrical job are better served by a specialty trade, since this is a general contractor that coordinates several specialties. Around Spokane, older homes built on modest foundations sit beside newer subdivisions on fresh lots, and each raises different questions. On a new build, ask how drainage and utility trenching will be handled before the foundation goes in, and how the roof is designed for snow. On an older house, accessibility work like wider doorways or a zero-step entry often reveals framing, wiring or insulation that needs attention, so ask how the contractor plans for what turns up once walls open.
