Corvallis Zoning & Land Use Guide
Key Zoning Facts
Corvallis Zoning Overview
Corvallis is home to Oregon State University and serves as the county seat of Benton County in the mid-Willamette Valley. The university is the city's largest employer and significantly influences housing demand, transportation patterns, and development activity. Corvallis is known for its highly educated population, cycling infrastructure, and commitment to sustainability. The city's zoning code is managed by the Community Development Department.
Corvallis faces typical college-town housing challenges, including rental demand near campus, neighborhood compatibility concerns, and housing affordability for both students and non-student residents. The city has worked to balance infill development with neighborhood preservation.
Key Zoning Districts
Corvallis uses residential zones (RS-3.5 through RS-20), mixed residential zones, commercial districts (GC, CC), industrial zones, and special area designations. The South Corvallis and downtown areas have specific planning frameworks encouraging mixed-use and higher-density development.
ADU Regulations
Corvallis allows ADUs in all residential zones per Oregon HB 2001. No parking or owner-occupancy is required. ADUs are an important housing option in this tight university-town market.
Development Process
Community Development processes permits and land use applications. Major projects are reviewed by the Planning Commission. Development must comply with both the city's comprehensive plan and Oregon statewide planning goals.
