West Jordan, UT Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 13-5B-3(A)'s lot and bulk standards table sets a "Maximum Building Coverage" column for every residential subzone alongside minimum lot area, yard setbacks and building height. minimum), get the most coverage at 45%; R-1-6, R-1-8, R-1-9 and R-1-10 are capped at 40%; the larger R-1-12 and R-1-14 lots drop to 35%. single-family lots) is capped at the highest residential figure of 50%, and the large-lot rural residential/estate zones R-R-20/R-E-20, R-R-30/R-E-30 and R-R-40/R-E-40 are all held to 35%. Agricultural zones (A-1, A-5, A-20) and the R-M mobile home/multi-family zone carry no maximum building coverage figure in this table (listed "n/a"), leaving those subject instead to the underlying setback, height and parking standards.

City Code section 13-2-3 defines "lot coverage" as the total horizontal area of a lot covered by any building or structure that extends above ground level, including covered automobile parking spaces, so garages and carports count toward the cap even though open patios and uncovered driveways do not. The limit also governs accessory construction: section 13-5B-8 requires an external accessory dwelling unit to meet the setback, height, lot coverage and separation requirements of 13-5B-3, meaning an EADU's footprint is added to the primary house's footprint when checking the zone's percentage cap.

Building Services and the Community Development Department check proposed footprints against these percentages during site plan and building permit review, before a permit is issued.
