Zoning Report
Columbus, OH Zoning
Columbus regulates land use through its city zoning code, zoning map, and public hearing processes administered by Building and Zoning Services. The city states that zoning governs land use, placement, spacing, setbacks, height, lot size, lot coverage, parking, and related site requirements. The available source set confirms a major 2024 zoning code document and a current city zoning portal, but the research provided here does not include a complete district-by-district use table for the full city, so this report is necessarily partial in several sections.
