Oregon State ADU Laws

Oregon has embraced ADU-friendly legislation to address housing needs. State law requires cities to allow ADUs on single-family residential lots.

Key Oregon ADU Regulations:

• Size Limits: Typically up to 800-900 sq ft, depending on local jurisdiction.
• Parking: Many Oregon cities have eliminated parking requirements for ADUs.
• Owner Occupancy: Oregon law limits owner-occupancy requirements.
• Approval Timeline: Streamlined permitting processes in most jurisdictions.

Tualatin Local Requirements

GatherADU works with Tualatin homeowners to navigate local building codes and zoning requirements specific to your property and neighborhood.

California law (AB 68, AB 881, SB 9, and subsequent legislation) guarantees your right to build ADUs. Cities cannot:

• Require owner-occupancy for ADUs permitted after 2020
• Require additional parking for ADUs near transit
• Charge impact fees for ADUs under 750 sq ft
• Deny ADUs that meet state minimum standards
• Impose lot coverage limits that prevent a 800 sq ft ADU

If you believe your ADU application is being unfairly denied, California HCD can intervene on your behalf.

Oregon ADU Legislation Overview

Oregon has been at the forefront of ADU-friendly legislation, recognizing ADUs as an important housing solution.

Key Oregon ADU Laws:

• HB 2001 (2019): Required cities to allow ADUs on all single-family residential lots.
• SB 458 (2021): Allowed lot splits for homes with ADUs.

Oregon ADU Benefits:

• Streamlined approval process
