Navigating ADU Permits: A Simplified Guide for Oregon Homeowners

December 18, 2024

Adding an Auxiliary Dwelling Unit (ADU) to your property can be an excellent investment, providing additional living space, rental opportunities, or even a comfortable space for multigenerational living. However, the permitting process can seem daunting. This guide is designed to simplify the ADU permit process for homeowners in Oregon, particularly those in Newberg and the surrounding areas.


Understanding ADU Basics


Before diving into the permit process, it's essential to understand what an ADU is and its benefits. An ADU is typically a secondary housing unit on a single-family residential lot. These units come in various forms, including detached units, converted garages, or basement apartments. They are increasingly popular for their ability to provide flexible living spaces that maximize property value.


Research Local ADU Regulations


The first step in navigating the ADU permitting process is to research local regulations. Oregon has statewide standards for ADUs, but local jurisdictions, like those in Newberg, may have additional zoning codes, development standards, and land use regulations. You can usually find this information on your local government or planning department’s website.


Key factors to consider:

  • Zoning Requirements: Determine if your property is zoned for an ADU. Some zones may have restrictions on the size, height, setback, and design of the ADU.
  • Lot Size and Coverage: Check the minimum lot size and maximum lot coverage provisions to ensure your property meets these standards.
  • Utility Connections: ADUs often require separate utility connections, including water, sewer, and electricity, which may require additional permits.


Design with Compliance in Mind


Once you understand the local regulations, the next step is to design your ADU in compliance with these requirements. Collaboration with a reputable construction company like PHD Construction Co. LLC can simplify this process. Our team of skilled professionals can help tailor your ADU design to meet both your needs and local code requirements.


Several design elements to consider:

  • Size and Dimensions: Ensure your ADU meets the maximum allowable size. In Oregon, ADUs are typically limited to a percentage of the main dwelling’s size or a specific square footage, whichever is smaller.
  • Access and Parking: Address requirements for separate access and parking provisions. Some jurisdictions may require off-street parking for the ADU.
  • Aesthetic Harmony: Strive to maintain architectural harmony with the main dwelling and the neighborhood. This may include matching rooflines, materials, and colors.


Submitting Your Permit Application


After finalizing your ADU design, the next step is to submit your permit application. In some areas, you may need multiple permits, including building permits, electrical permits, plumbing permits, and possibly a land use permit.


Here's a step-by-step guide for submission:

  • Prepare Required Documents: Gather all necessary documents, including site plans, floor plans, elevation drawings, and any required environmental or energy efficiency reports.
  • Complete Application Forms: Fill out all required application forms meticulously. Incomplete applications can result in delays or rejections.
  • Pay Appropriate Fees: Be prepared to pay various application fees. Costs can vary widely based on your location and the complexity of your ADU project.
  • Schedule Inspections: Once your permit is approved, schedule required inspections. These will typically include preliminary foundation inspections, rough carpentry, plumbing, and electrical inspections, and final inspections once the ADU is completed.


Work with Experienced Professionals


The ADU permitting process can be complex and nuanced, making it essential to work with experienced professionals. PHD Construction Co.

Common Challenges and How to Overcome Them


Navigating the ADU permit process may present some challenges. Here are a few common obstacles and tips on how to overcome them:

  • Lengthy Approval Times: Permit processing times can be lengthy. To mitigate this, ensure your application is complete and complies with local requirements from the start.
  • Design Alterations: Design changes may be necessary to meet regulatory standards. Work closely with your construction team to make these adjustments efficiently.
  • Budget Constraints: Unanticipated costs can arise. Keep a contingency budget and work with a contractor who provides transparent, detailed cost estimates.
