Salem, the vibrant capital of Oregon in Marion County, is an ideal location for custom ADUs perfect for multigenerational living, rental income, or extra space. With landmarks like the Oregon State Capitol and its golden pioneer statue, it's a dynamic community ready for your next project.
In Salem, ADUs are typically limited to a maximum of 900 square feet or 75% of the primary home’s square footage (whichever is smaller), with a minimum size often around 350 sq ft to meet health code requirements. We help you design within these limits while maximizing usable space and value—whether detached, attached, or a conversion.
Costs vary based on size, type (detached vs. conversion), finishes, and site conditions, but most Salem ADUs range from $100,000–$250,000+. We provide transparent, upfront pricing with no hidden fees, including site work, permits, construction, and your chosen upgrades. During your free consultation, we’ll give you a personalized estimate based on your goals and property.
Many clients come to us with just general ideas. We can help you discover your preferences through our portfolio, idea books, and by asking the right questions about your lifestyle. We have a systematic approach to guiding you through decisions without overwhelming you.
Popular upgrades include enhanced kitchen features (custom cabinetry, premium appliances), primary bathroom luxury elements, smart home technology, outdoor living spaces, and upgraded flooring. We can show you the impact of various upgrades on both the initial cost and long-term value of your home.
Yes, we manage the entire permitting process as part of our service, including submittal, fees, revisions, and scheduling all required inspections. Our familiarity with local building departments helps avoid delays. We keep you informed of the permitting status but handle all the paperwork and meetings.
No owner-occupancy requirement exists for most ADUs in Salem (thanks to Oregon state law). Off-street parking is often not required for the ADU itself. Rentals are allowed (including long-term), but short-term rentals like Airbnb may have restrictions. We stay up-to-date on current Salem and Oregon regulations to ensure your project complies fully.
