ADU Contractors in Beaverton, Oregon: Building in a Fast-Growing Tech Hub
Beaverton, Oregon, home to Nike's global headquarters and a thriving tech corridor, has experienced significant population growth in recent years. This rapid expansion has made Accessory Dwelling Units (ADUs) an increasingly popular housing solution for homeowners looking to maximize their property value, generate rental income, or house extended family members. Finding experienced ADU contractors in Beaverton, OR is essential to navigating the city's specific building requirements and creating a high-quality living space.
Beaverton ADU Regulations and Zoning Requirements
Before breaking ground, homeowners must understand that Beaverton ADU construction is governed by Washington County and City of Beaverton zoning codes. Beaverton falls under Oregon's statewide ADU-friendly legislation, which has significantly loosened restrictions in recent years. Key regulations that qualified ADU builders in Beaverton must work within include:
- Owner-occupancy requirements have been eliminated statewide in Oregon, allowing non-owner-occupied properties to include ADUs
- ADUs are permitted in all residential zones throughout Beaverton
- Detached ADUs are generally limited to 800 square feet or 75% of the primary dwelling's size, whichever is smaller
- Setback requirements typically mandate a minimum of 5 feet from rear and side property lines
- Height restrictions for detached ADUs are generally capped at 25 feet
- System Development Charges (SDCs) may apply, though Oregon law limits certain fees for smaller ADUs
Types of ADUs Built by Beaverton Contractors
Experienced ADU contractors in Beaverton are skilled in constructing several types of accessory dwelling units suited to the area's typical residential lots and architectural styles. The most common ADU types include:
- Detached ADUs (DADUs): Standalone structures built in backyards, popular in Beaverton's established neighborhoods
- Attached ADUs: Units connected to the primary home, sharing at least one wall
- Garage Conversions: Transforming existing garages into livable spaces, a cost-effective option for many Beaverton homeowners
- Basement Conversions: Converting existing basement space into a fully permitted dwelling unit
Why Hire a Local Beaverton ADU Contractor?
Working with a local ADU contractor in Beaverton, Oregon offers distinct advantages.

They understand the area's soil conditions, common utility configurations, and neighborhood design standards that can impact your project timeline and budget.
When selecting the best ADU builder in Beaverton, look for contractors who are licensed with the Oregon Construction Contractors Board (CCB), carry proper liability insurance, and have a proven portfolio of completed ADU projects in the Beaverton and greater Portland metro area. A qualified contractor will guide you through design, permitting, construction, and final inspections, ensuring your ADU is built safely, legally, and to the highest standards.
