Yucaipa, CA Home Business: Zoning & Home Occupation Permits (2026)

Development Code § 84.0615 treats home occupations and cottage industries as commercial uses that are accessory to a residential land use. They are permitted only where the use will clearly not alter the character or the appearance of the residential environment, and only with a Home Occupation Permit. The section splits its standards into three groups: general standards for both uses in subsection (b), home occupation standards in subsection (c), and cottage industry standards in subsection (d).

The general standards require the work to be confined to an enclosed structure under (b)(3). Item (b)(4) bars any change to the appearance of the structure through colors, materials, construction, lighting or signs, and bars sounds, noises and vibrations that make the premises differ from residential character. A tenant must submit notarized written permission from the property owner under (b)(5), and all permits required by other agencies go in with the permit application under (b)(6). Noise cannot exceed 55 dBA at the property lines at all times under (b)(7), and glare cannot spill onto an adjacent parcel under (b)(8). Hazardous materials are used and stored under San Bernardino County Department of Environmental Health Services, Hazardous Materials Division regulations per (b)(9).

Subsection (c) allows a home occupation on any property in a land use district that allows residential uses. All employees, partners and operators must be members of the resident family and live on the premises, and up to 25% or 250 square feet of floor area, whichever is greater, can hold storage. Subsection (d) allows a cottage industry only on properties of at least one acre in districts with a minimum lot area of 2.5 acres or greater. Two workers can be non-family, and storage can reach 35% of floor area or 500 square feet, whichever is greater.
