What is an ADU?

An ADU, or Accessory Dwelling Unit, is a secondary housing unit on a single-family residential lot. ADUs come in various forms, including detached units, garage conversions, basement apartments, or additions to the existing structure. They typically include all the amenities of a small home, such as a kitchen, bathroom, and living space.

Why Build an ADU?

Building an ADU offers numerous benefits:

• Increased Property Value: Adding an ADU can significantly boost the resale value of your home.
• Additional Income: Rent out the ADU for extra monthly income.
• Multigenerational Living: Provide a comfortable living space for aging parents or adult children.
• Flexible Use: Use the ADU as a guest house, home office, or personal retreat.

Steps to Construct an ADU

1. Check Local Regulations and Zoning Laws

Before you begin planning your ADU, it’s crucial to understand the legal requirements in your area. Your ability to build an ADU is subject to state and city zoning, ordinances, and building codes. For example, in regions like Bend, OR, and Tigard, OR, specific regulations may dictate the size, placement, and design of your ADU.

• Zoning Laws: Verify that your property is zoned for an ADU.
• Building Codes: Ensure that your plans comply with local building codes.
• Permits: Obtain the necessary permits from your local building department.

2. Plan Your ADU Project

Once you have a clear understanding of the legal requirements, the next step is to plan your ADU project. This involves deciding on the type of ADU you want to build and how it will be used.

• Type of ADU: Decide between a detached unit, garage conversion, basement apartment, or addition.
• Purpose: Determine if the ADU will be used for rental income, housing a family member, or another purpose.
• Design and Layout: Create a floor plan that maximizes space efficiency and meets your needs.

3. Designing Your ADU

Designing an ADU requires careful consideration of space, functionality, and aesthetics. Working with an architect or designer can help ensure that your ADU is both practical and visually appealing.

• Space-Efficient Designs: Opt for designs that make the most of limited space.
• Custom ADU Design: Tailor the design to match your existing home’s style and layout.
• ADU Floor Plans: Develop detailed floor plans that include all necessary features.

4. Budgeting and Financing

Building an ADU is a significant financial investment. It’s essential to create a budget and explore financing options to ensure you can cover the costs.

• Cost Estimates: Obtain cost estimates for materials, labor, permits, and other expenses.
• Financing Options: Consider home equity loans, personal savings, or other financing methods.
• Budget Planning: Create a detailed budget to track your expenses throughout the project.

5. Obtaining Permits

Navigating the permit process can be complex, but it’s a critical step in building your ADU. Each locality has specific requirements, so it’s essential to understand and follow the process.

• Building Permits: Submit your ADU plans to the local building department for approval.
• Zoning Permits: Ensure your project complies with zoning regulations.
• Inspections: Schedule inspections at various stages of construction to ensure compliance.

6. Hiring Contractors

Hiring experienced contractors can make a significant difference in the quality and efficiency of your ADU construction. Look for professionals with experience in building ADUs and a strong reputation.

• Selecting Contractors: Interview multiple contractors and check references.
• Contract Agreements: Ensure you have detailed contracts outlining the scope of work, timelines, and costs.
• Project Management: Maintain regular communication with your contractors to keep the project on track.

• Installing Utilities: Ensure that plumbing, electrical, and HVAC systems are properly installed.

• Certificate of Occupancy: Obtain a certificate of occupancy, allowing the ADU to be legally inhabited.
