Clackamas County

Clackamas County covers a large area south and east of Portland, from suburban communities like Oregon City and West Linn to rural areas around Molalla, Canby, Estacada, and Sandy. 3-A Construction, LLC serves property owners across the county, with most job sites about 50 to 75 minutes from our Jefferson headquarters depending on location. The county's varied terrain, from valley floor to mountain foothills, means site conditions vary widely and our experience across different soil types and slopes is a real advantage.

Clackamas County's Planning and Zoning Division oversees development in unincorporated areas, and the county has numerous manufactured home parks and rural residential properties where manufactured homes are the primary housing type. Individual cities within the county maintain their own permitting processes. We handle the full permitting and coordination process regardless of jurisdiction, ensuring compliance with all local requirements.

Our Clackamas County work includes manufactured home replacement in established parks, new installations on rural acreage, site development on the basalt-influenced soils common in the area, septic system installation, and foundation construction. We also serve the growing demand for ADUs in Clackamas County's urban and suburban zones.
