Jurupa Valley, CA Accessory Structures: ADU Rules (2026)

Jurupa Valley Municipal Code Sec. 290, as amended by Ordinance No. 2025-22, sets two approval tracks. ADUs of 800 sq ft or less that meet Government Code Sec. 66323 standards need only a building permit filed with Building and Safety; larger or nonconforming ADUs require a ministerial planning application decided within 60 days under Government Code Sec. 66317, with no public hearing. Development standards: a detached ADU may not exceed 850 sq ft (1,000 sq ft if more than one bedroom) and 16 feet in height (18 feet within a half mile of a major transit stop or on a multifamily lot, 20 feet to match the primary dwelling roof pitch near transit); an attached ADU may not exceed 50 percent of the primary dwelling's gross floor area or 25 feet in height; side and rear setbacks are 4 feet, with no setback required for conversions of existing structures.

One off-street parking space is required unless the ADU is near transit, within a historic district, or created within an existing dwelling or accessory structure. A recorded covenant must bar separate sale and short-term rental under 31 days. Impact fees are waived for ADUs under 750 sq ft. The city also runs a Permit-Ready ADU Program with free pre-approved plans in four prototypes (500 to 1,000 sq ft) and three architectural styles. In May 2026 the City Council was adopting Ordinance No. 2026-04 (ZCA26001) to implement SB 543, AB 1154, and SB 9 (effective Jan.

1, 2026), which allow up to three accessory units (one conversion ADU, one detached ADU, and one JADU) and four total dwellings on a single-family lot, and impose a 15-business-day application completeness review.
