Rohnert Park, CA Building Setbacks & Zoning: Lot Coverage Limits (2026)

020 adopts a single development standards table covering every zoning district's minimum lot size, width, depth, density, height, setbacks, open space and Maximum Lot Coverage (Percent), the table's final column. 010 direct a reader to find the district on the left of the table and read across to the coverage figure in that district's row, so a coverage percentage only means something tied to its own district, not as a citywide number. The R-R (Rural Residential) row caps coverage at thirty percent, the most restrictive figure in the table, reflecting the district's forty-thousand-square-foot minimum lot size at the city's rural edge.

R-E (Estate Residential) allows forty percent. 020(C), is capped at fifty percent, while the higher-density R-M and R-H residential districts are held to forty percent despite their smaller minimum lot sizes. Commercial districts run higher: C-O caps at fifty percent, C-N, C-R and I-L cap at sixty percent, while the mixed-use M-U and DTM-U districts top out at eighty percent and the downtown residential DTR-H district is held to forty percent. The table's footnotes qualify related figures, not coverage directly: footnote (13) lets rear yard setbacks shrink to ten feet for narrow one-story additions, and footnote (18) sets floor area ratio maximums, but no footnote is attached to any Maximum Lot Coverage cell, so the printed percentages apply without exception language in the table itself.
