MCMINNVILLE, OR – July 06, 2026 – PRESSADVANTAGE –
All Building Construction, an owner-operated general contractor based in McMinnville, today announced the formal launch of a dedicated home addition and accessory dwelling unit construction service for homeowners across Yamhill County and the surrounding Willamette Valley. The service is led by company founder Mark Prine, who has held an active Oregon Construction Contractors Board license since 2006 and oversees every project from initial consultation through final walkthrough.
The new service offering responds to a pattern the company has tracked across nearly 20 years of Yamhill County projects: homeowners in McMinnville, Newberg, Dayton, and the surrounding communities are increasingly looking to expand existing homes rather than move, often to accommodate multigenerational living, rental income, or home office space. Accessory dwelling units, commonly referred to as ADUs, are small self-contained living spaces built on the same lot as a primary residence. They can take the form of a detached cottage, a converted garage, or an addition built above or alongside the main home.
All Building Construction handles each addition and ADU project as a full-scope build. That includes site evaluation, design coordination, permitting through the local jurisdiction, foundation and framing, mechanical and electrical rough-in, finish carpentry, and the final inspection process. The company pulls all required permits and coordinates directly with city and county inspectors so the homeowner is not left navigating code requirements alone. Mark Prine personally walks each site before work begins and remains the primary point of contact throughout the build.
The company brings a perfect Oregon CCB record to the new service line, with no complaints, penalties, or suspensions logged against license number 174384 since it was issued in 2006. The in-house crew includes trained laborers and journeymen who handle framing, custom carpentry, and finish work without relying on rotating subcontractor teams for core scopes. The company has completed projects ranging from a 100-year-old barn renovation to a multi-window wall addition with a covered porch, drawing on Mark Prine’s hands-on construction experience across Oregon, California, Hawaii, and Kenya.
The service is available to homeowners in McMinnville, Newberg, Carlton, Dayton, Hillsboro, Sherwood, Wilsonville, Dundee, Amity, Lafayette, and the broader Yamhill County region. Each project begins with an on-site consultation and a detailed written estimate provided before any work is scheduled, reflecting the company’s commitment to transparent pricing. During the build phase, the team conducts morning check-ins with the homeowner to confirm the previous day’s work meets expectations before moving forward.
“After almost 20 years of doing this work in Yamhill County, I’ve watched a lot of families wrestle with the same question: do we sell and start over, or do we make the home we have work better. An addition or an ADU is often the right answer, but only if it’s built honestly, permitted correctly, and finished the way the homeowner pictured it. That’s the work I want to put my name on, and that’s the work I show up to oversee every day,” said Mark Prine, owner of All Building Construction.
