Aurora's UDO limits lot coverage (buildings and impervious surfaces) by zoning district. Typical residential coverage is 30-40% of lot area. All structures including house, garage, shed, and ADU count toward coverage.
Aurora's Unified Development Ordinance establishes maximum lot coverage for each zoning district. Lot coverage includes all buildings, structures, and impervious surfaces such as driveways, patios, and walkways. Typical single-family residential zones allow 30-40% maximum coverage. All structures including the primary dwelling, garage, sheds, ADUs, and carports count toward the total. Driveways and paved patios also count as impervious coverage. Permeable pavers and green infrastructure may receive partial credit. The building division calculates coverage during the permit review process.
Exceeding lot coverage: must reduce or seek variance. Unpermitted coverage: code violation.
