Yucaipa, CA Accessory Structures: Garage Conversions (2026)

Yucaipa's garage conversion standard is written into Chapter 17 of the Development Code, which governs two-unit residential development and urban lot splits under Senate Bill 9. It appears as paragraph (14) of the objective design standards in § 88.01715(a). The chapter applies only to lots designated for single family residential uses under the City's General Plan, and § 88.01701(b) screens out parcels with prime farmland, wetlands, or historic resources, and parcels in a high or very high fire hazard severity zone unless fire hazard mitigation measures are met.

When a garage becomes a new unit, the garage door opening is removed and closed in. It is replaced with exterior wall coverings, or residential windows, doors, or a combination, to match the existing exterior garage wall covering and detailing of the structure. Paragraph (13) adds that accessory dwelling units developed within or added onto an existing non-historic structure must match its architectural style, massing, and detailing, including siding, windows, doors, roofing, trim, light fixtures, hardware and railings, and roof slopes and building entry design.

Parking still counts. Paragraph (4) requires one parking space for each duplex unit created, unless the parcel is within one-half mile of a high-quality transit corridor or a major transit stop, or a car share vehicle is located within one block. Parking cannot be provided within a front setback, and rear lot parking is accessed via an alley if there is one. Paragraph (19) allows a 400 square foot garage or carport, not to exceed 12 feet in height, no closer than four feet from a side or rear property line, or otherwise within the district setbacks.

Under § 88.01710(a), every SB 9 project goes through the City's Land Use Compliance Review process to determine whether the criteria for ministerial approval are met. Paragraph (12) requires a complete landscaping and irrigation plan approved by the Development Services Department before building permits issue for a two-unit development.
