Amity Manufactured Home Installation & Site Development
Amity is a small rural community in southern Yamhill County nestled against the Eola-Amity Hills. 3-A Construction, LLC provides manufactured home installation and site development to Amity-area property owners from our Jefferson headquarters, about 40 minutes northwest.

About Amity
Amity sits at the southern edge of Yamhill County where the flat valley floor meets the Eola-Amity Hills, a prominent ridgeline that separates the Yamhill Valley from the Willamette Valley to the east. The terrain immediately around Amity is gently rolling to flat, but properties on the surrounding hillsides can have significant slopes. Soils in the area include Amity silt loam on the valley floor, a poorly drained soil series actually named for this community, and Nekia and Jory silty clay loams on the hillsides. The Amity silt loam is notorious for seasonal water retention and requires careful drainage design and appropriate foundation engineering. Our crews are experienced with these conditions and plan accordingly for every project in the area.
Amity's small size means it has limited city planning resources, and many of the properties we work on in the Amity area are in unincorporated Yamhill County, falling under county planning and building permit jurisdiction. Yamhill County Environmental Health handles septic system permitting for rural properties, which is critical because virtually all residential properties outside the small Amity city boundary rely on individual septic systems. We manage the full permitting process including septic feasibility testing, system design, county approvals, and final inspection coordination.
Amity is surrounded by the vineyards and hazelnut orchards that define this part of the Yamhill Valley. The Eola-Amity Hills AVA (American Viticultural Area) is one of Oregon's premier wine-growing regions, and the hillsides above Amity are dotted with vineyards and tasting rooms. The Amity School District serves the local community. Key work areas include properties along Highway 99W through town, the Bellevue Highway toward Salem, the Amity-Dayton Highway to the north, and rural parcels in the Eola-Amity Hills accessed from Walnut Hill Road, Rice Lane, and the various vineyard roads in the area.
From our Jefferson headquarters, Amity is approximately 40 minutes northwest via Highway 99W through Monmouth, or alternatively via Highway 22 west and Highway 99W north. The drive is straightforward, and Amity's location between McMinnville and Monmouth means we often coordinate Amity projects with other work in the southern Yamhill County area. Our crews can stage materials and equipment efficiently for Amity-area projects.
Amity's rural character, small-town feel, and proximity to wine country make it an appealing location for property owners seeking affordable acreage. Manufactured homes are a practical and economical housing choice for rural Amity-area parcels, and our complete site development package ensures that every aspect of the installation is handled professionally, from clearing and grading through septic installation, foundation work, home placement, and final utility connections.
