read moreOregon is a trailblazer when it comes to accessory dwelling unit (ADU) legislation. In 2017, Oregon passed House Bill 2007, which required cities with populations over 2,500 to allow ADUs in single-family residential zones. Then in 2019, Senate Bill 10 further pushed Oregon's housing reform by encouraging higher-density development statewide. These landmark laws make Oregon one of the most ADU-friendly states in the country, creating a thriving market for experienced ADU contractors in Oregon who understand the evolving regulatory landscape.
While state law sets a baseline, individual cities and counties in Oregon maintain their own specific rules. Portland, Eugene, Bend, and Salem each have unique zoning codes, setback requirements, and permitting processes that ADU contractors must navigate carefully. For example, the City of Portland allows both attached and detached ADUs and has worked to reduce system development charges (SDCs) to encourage ADU construction. Skilled Oregon ADU contractors stay up to date with these local nuances to ensure every project moves forward without costly delays.
Experienced ADU contractors in Oregon are well-versed in building a variety of unit types to suit different property configurations and homeowner needs. Common ADU types include:
Choosing the right ADU contractor in Oregon is critical to the success of your project. Oregon requires all general contractors to be licensed through the Oregon Construction Contractors Board (CCB). Homeowners should always verify a contractor's CCB license before signing any agreement. Beyond licensing, look for contractors with specific ADU experience, a strong portfolio of completed projects, and familiarity with Oregon's energy efficiency standards under the Oregon Residential Specialty Code (ORSC).
Building an ADU in Oregon offers significant advantages for homeowners. These include:
With Oregon's supportive legislative environment and a growing network of qualified ADU contractors, now is an excellent time for Oregon homeowners to invest in accessory dwelling unit construction. Working with a licensed, experienced contractor ensures your ADU is built safely, legally, and to the highest standards.
