ADU Construction in Bend, Oregon
Rockin' K General Contracting has been designing and building accessory dwelling units in Bend, Oregon since 2016. Whether the goal is rental income, housing for family members, or long-term resale value, an ADU represents a significant investment in a property, and the company builds with long-term performance in mind.
The crew works across Bend's varied property types, including urban infill lots on the east side, established west-side neighborhoods, acreage parcels in Tumalo, and resort properties in Sunriver. Rockin' K also serves Redmond, about 15 minutes north of Bend. Each ADU is designed around the specific conditions of the lot it sits on, including setbacks, utility access, slope, and the applicable zoning rules under the City of Bend or Deschutes County.
- Permitting handled through the City of Bend and Deschutes County
- Work kept largely in-house rather than subcontracted out
- Single point of contact from initial call through final walkthrough
- Engineer coordination, inspections, and code compliance included
- Units designed for long-term rental, short-term rental, or family use
Types of ADUs Built
Detached ADUs are fully separate structures, typically 400 to 900 square feet, with their own kitchen, bathroom, and entrance. This option offers the most privacy and generally the strongest rental income potential, along with the most flexibility in layout. It's the ADU type most frequently requested by Bend clients.
Garage Conversion ADUs turn an existing attached or detached garage into a code-compliant living unit. Because the foundation, walls, and roof already exist, this is typically the most cost-effective path, often running $200,000 to $300,000. It also tends to come with a shorter construction timeline, which suits tighter budgets or faster schedules.
Attached ADUs are new additions built onto the primary home, complete with a separate entrance, kitchen, and bath. This approach works well for multi-generational living situations or on lots where setback restrictions or limited space rule out a detached structure.
The Build Process
Rockin' K structures its ADU projects into four stages, starting with a free 15-minute introductory call to discuss the project, timeline, and budget, and whether an ADU is a realistic fit for the lot. This is followed by a site visit and feasibility review, where the team assesses setbacks, utilities, slope, and access, and checks zoning requirements specific to the property.
From there, clients receive a detailed written proposal with a clear cost breakdown. Once approved, Rockin' K manages permitting through the City of Bend or Deschutes County, coordinating directly with engineers and inspectors. Construction is carried out by the in-house crew, with a dedicated point of contact, regular progress updates, and a final walkthrough before the project is considered complete.
ADU costs in Bend generally range from $250,000 to $400,000, depending on size, finish level, and site conditions, with garage conversions on the lower end and fully custom detached builds at the higher end. Permitting for an ADU in Bend typically takes 6 to 12 weeks, and construction usually runs 4 to 7 months once permits are approved, with garage conversions often completing faster, in the 3- to 5-month range.
Long-term rentals are allowed throughout Bend, while short-term rental eligibility depends on the property's zoning. As of a 2025 code update, the City of Bend also allows up to two ADUs on a single-family lot in many cases, with the second unit capped at a smaller size, depending on lot size, setbacks, and available utilities.
