Our Services
General Contracting
As your general contractor, Kempf Construction LLC manages every moving part of your build, including design coordination, permitting with the City of Lebanon and Linn County, scheduling, licensed subcontractors, materials, inspections, and final delivery. Whether you are expanding a home, opening a storefront, or building from the ground up, we keep your project organized, fully code compliant, and on schedule.
Residential Construction
We build homes for the way Lebanon lives. Our residential construction services cover new single-family homes, full structural framing, and ground-up builds on infill lots, foothill parcels, and acreage throughout the area. From energy-efficient designs suited to the Willamette Valley climate to layouts that fit both Lebanon's established neighborhoods and its fast-growing subdivisions, we build durable, beautiful homes designed to last.
Commercial Construction
Lebanon business owners and developers rely on us for tenant improvements, retail and office build outs, and complete commercial construction. We coordinate with architects, engineers, and city officials to deliver code compliant commercial spaces that include restaurants, professional offices, medical facilities, retail environments, and mixed use projects. Every build is managed to minimize disruption to your operations and maintain a clear, predictable timeline.
Remodeling
Whether you own an established home in central Lebanon or a newer build near the medical campus, our remodeling services bring new life to existing spaces. We handle whole home renovations, room by room updates, and structural remodels that improve function, comfort, and resale value while respecting the character of your home.
Home Additions
Need more space without leaving Lebanon? Our home addition services add square footage where you need it most; primary-suite additions, second stories, expanded living rooms, sunrooms, and bump-outs. We tie new construction seamlessly into your existing structure so the addition looks and feels original to the home.
ADU Construction
Accessory dwelling units are one of the smartest ways to add value, rental income, or multigenerational living space in Lebanon. With the city’s growing medical campus and student population, rental demand continues to rise. As an experienced ADU builder, we handle detached and attached units, garage conversions, and shop conversions that are fully permitted under Oregon and City of Lebanon ADU rules. ADUs are popular near the medical campus for rental income and on the larger foothill and acreage lots throughout the area, offering flexibility and long term value for homeowners.
