The Union County Zoning, Partition, and Subdivision Ordinance (UCZPSO) implements the county’s Comprehensive Plan and Oregon Statutes and Rules and establishes the rules for land use, development, and property divisions throughout unincorporated Union County. This ordinance defines what uses are allowed in each zone, sets standards for building placement and development, and outlines the processes for permits, variances, and land divisions. Whether you’re planning to build a home, divide property, or pursue other development, the UCZPSO provides the framework and requirements you’ll need to follow. For questions or assistance navigating the ordinance, contact the Planning Department at (541) 963-1014 or visit us at 1001 4th Street, Suite C in La Grande.
