What to Know Before Hiring an ADU Builder in Central Oregon

Accessory Dwelling Units (ADUs) are transforming the way Central Oregon families live. From Bend to Redmond and Sisters, homeowners are investing in ADUs to accommodate multi-generational living, generate rental income, or create flexible home office space. But building an ADU is a major investment, and choosing the right builder is critical to ensure a smooth project, on-time completion, and a high-quality result.

Here’s what every homeowner in Central Oregon should know before hiring an ADU builder.

1. Check Local Experience

Not every contractor has experience building ADUs, especially in Central Oregon where zoning rules, building codes, and climate considerations can vary widely.

Tip: Look for a builder who has completed multiple ADU projects in Central Oregon. Ask for references, visit completed projects, and check online reviews. Local experience helps ensure compliance with city regulations and smooth permit approvals.

2. Verify Licensing and Insurance

Always verify that your builder is licensed, bonded, and insured.

Why it matters: ADU construction involves plumbing, electrical work, and structural modifications. Proper licensing ensures your builder is qualified to handle these tasks safely. Insurance protects you from liability in case of accidents or damage during construction.

3. Understand Permitting and Zoning

Central Oregon cities—Bend, Redmond, Sisters, and Sunriver—each have specific regulations for ADUs. This includes size limits, setbacks, parking requirements, and occupancy rules.

Tip: Ask your builder how they handle permits and inspections. Experienced builders can guide you through the process and avoid costly delays.

4. Discuss Budget and Hidden Costs

Many homeowners underestimate the total cost of building an ADU. Beyond construction, consider:

• Utility hookups and meters

• Site preparation and grading

• Landscaping

• Architectural or engineering fees

Tip: Get a detailed written estimate and contingency plan. Expect to set aside 10–20% of the budget for unexpected costs.

5. Clarify Timeline and Communication

ADU projects can take 6–12 months, depending on size, design, and permitting. Delays are common if expectations aren’t clear.

Tip: Ask your builder about:

• Estimated start and completion dates

• How often they provide updates

• Who will be your primary point of contact

Clear communication prevents misunderstandings and ensures your ADU is delivered on time and on budget.

6. Prioritize Design and Functionality

A beautiful ADU is important, but functionality matters just as much. Consider:

• Who will live in the unit (seniors, adult children, renters)

• Storage and layout needs

• Privacy from the main house

Tip: Work with a builder who collaborates with architects or designers to create an ADU that fits your family’s lifestyle.

Hiring the right ADU builder in Central Oregon is essential to ensure your project is safe, compliant, and tailored to your family’s needs. By prioritizing local experience, proper licensing, permitting expertise, budget transparency, and functional design, you can avoid costly mistakes and enjoy a flexible, high-quality ADU for years to come.
