Weld County, CO Building Setbacks & Zoning: Lot Coverage Limits (2026)

Sec. 2 below lists the Bulk Requirements for the R-1, R-2, R-3, R-4 and R-5 Zone Districts. " Row G of that table sets Maximum LOT COVERAGE at 50% for R-1 (Low-Density Residential), 50% for R-2 (Duplex Residential), 60% for R-3 (Medium-Density Residential), 70% for R-4 (High-Density Residential, no longer permitted to be created after July 25, 2019 per Sec. 23-3-140), and 60% for R-5 (Manufactured Home Residential). The same table sets a 6,000-square-foot minimum lot size in R-1, R-2, R-3, and R-5, dropping to 3,000 square feet in R-4, and a 50-foot minimum lot width across all five districts, so the coverage percentage always applies against a lot that already meets those size floors.

A landowner who wants a structure that would push a lot over its row-G cap does not simply get denied: Sec. 2 lists "STRUCTURES exceeding maximum LOT COVERAGE" as a Use by Special Review in the R-1 district, with the identical provision repeated for R-2 through R-5, meaning the Planning Commission and Board of County Commissioners can approve an exception through the same $3,000 Special Review process used for Child Care Centers and other higher-impact uses. Outside the residential districts, the Commercial and Industrial Zone Districts run on a separate, more permissive bulk standard, Sec. 23-3-250(D) and Sec. 23-3-340(D), which each cap lot coverage at 85 percent instead of the 50-70% residential range.
