Keizer Manufactured Home Installation & Site Development
Keizer borders Salem to the north and is one of Marion County's fastest-growing cities. 3-A Construction, LLC provides complete manufactured home installation and site development services to Keizer property owners from our Jefferson headquarters, just 20 minutes south.

About Keizer
Keizer occupies a relatively flat area on the east bank of the Willamette River, directly north of Salem. The city's topography is predominantly level valley floor with Willamette silt loam soils that are generally well-suited for construction but can present drainage challenges during the wet season. Our crews are experienced with Keizer's soil conditions and design site drainage, foundations, and septic systems accordingly. The water table can run high in parts of Keizer near Claggett Creek and the Willamette River, which factors into foundation and utility planning.
The City of Keizer Community Development Department handles planning and building permits within city limits. Keizer has specific manufactured dwelling standards that differ from neighboring Salem, including setback requirements, skirting specifications, and site plan expectations. We manage the full permitting process with the city, including site plan preparation, application submittal, and inspection scheduling. Our long history of working with Keizer's planning staff means we understand their expectations and can keep your project moving without unnecessary delays.
Keizer has several established manufactured home communities, particularly along Cherry Avenue, River Road, and Chemawa Road, where homeowners regularly replace aging units with modern manufactured homes. We also work on individual residential lots throughout the city where manufactured homes are permitted, including properties in the Keizer Station area and neighborhoods east of River Road. The city's relatively compact layout and accessible road network make it efficient for our crews to mobilize from Jefferson.
From our headquarters at 1690 Harvey St SE in Jefferson, we reach Keizer job sites in approximately 20 minutes heading north on I-5 or River Road. This short drive means we can be on-site quickly for evaluations, and we often manage multiple Keizer projects during the same period. Our services in Keizer include complete manufactured home installation, foundation construction, site grading and excavation, septic system installation for properties not connected to municipal sewer, demolition of old structures, and ADU construction.
