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

Chino Municipal Code § 20.04.040 sets the development standards for every single-family residential zoning district in Table 20.04-3, adopted with the 2010 zoning code (Ord. 2010-05, § 1(exh. A), 2010) and most recently amended by Ord. 2021-001, §§ 3, 4, 2021. The table's 'Lot Coverage, Maximum' row reads '25%' for the RD 1 (one-acre minimum lot) and RD 2 (20,000-square-foot minimum lot) districts, then '60%' for the RD 4.5 (7,200-square-foot lot) and RD 8 (4,500-square-foot lot) districts, meaning the smallest-lot single-family zones allow more than double the proportional building footprint of the estate-lot zones.

Lot coverage is not the only footprint control in the table. The 'Floor Area Ratio, Maximum' row caps total floor area at .20 in RD 1, .30 in RD 2, .50 in RD 4.5 and .55 in RD 8, a separate ceiling that accounts for multi-story square footage rather than ground-floor footprint. The table also sets a 'Front Yard Landscape Coverage, Minimum' of 70% in RD 1 and RD 2 and 50-60% in RD 4.5 and RD 8, which indirectly limits how much of the front setback area can be paved or built upon even within an allowed lot-coverage percentage.

These standards apply only to single-family districts; Table 20.04-4, governing the RD 8 through RD 20 multifamily districts, does not carry a maximum lot coverage figure at all, instead controlling density (8 to 20 dwelling units per acre) alongside a 'Landscape Coverage, Minimum' of 40% and building separation standards. A property owner in a single-family district who wants to exceed the Table 20.04-3 lot coverage figure has no administrative waiver built into this section; the standard applies to 'all lots and structures located in single-family residential zoning district' under § 20.04.040(A).
