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

The City of Yucaipa caps how much of a residential lot can be built or paved through two rows in each district's standards table: Maximum Lot Coverage and Maximum Building Coverage. The Rural Living (RL) District, § 84.0320, prints 40% for both. The Single Residential (RS) District, § 84.0325, prints 55% lot coverage and 40% building coverage. The Multiple Residential (RM) District, § 84.0330, prints 60% for both, and the High Density Multiple Residential (RM-24) District, § 84.0335, prints 60% lot coverage and 50% building coverage. The RM section states that Single Residential (RS) District development standards apply to all single-family land uses within the RM District, so a single-family house there falls under the RS 55% and 40% figures.

The two terms are not the same. Section 812.12130 defines lot coverage as the percentage of a lot that has been altered to create a surface area that is either impervious or is covered by a structure. Building coverage means the percentage of lot surface area occupied by any building, but it does not include roadways, swimming pools, tennis courts, or solar collection devices which are on top of, enclosed, or covered by a building. Impervious paving therefore counts toward the lot coverage figure under that definition.

The coverage rows sit beside minimum lot size: 1.0 gross acre in RL (map suffix will modify) and 7,200 sq. ft. in RS and RM. Section 87.0340 fixes how lot area is measured. Under one acre, the area is that within the legal boundaries exclusive of abutting planned rights-of-way. At one acre or greater, it includes planned right-of-way up to the centerline, not to exceed 60 feet from the legal boundary. Under § 84.0105(c), if other Development Code provisions and a land use district conflict, the more stringent provision prevails unless a less stringent one specifically modifies it.
