ADU rules in Perris, CA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
The City of Perris permits accessory dwelling units and junior ADUs ministerially under its own Zoning Code Chapter 19.81, implementing California Government Code Chapter 13 (Gov. Code 66310 et seq.). Detached ADUs may reach 1,200 sq ft, JADUs are capped at 500 sq ft, and ADUs may not be rented for under 31 days.
Perris adopted Chapter 19.81 of its Municipal Code (rewritten in full by Ordinance No. 1449, adopted Feb. 11, 2025) to implement California's statewide ADU law, Government Code Chapter 13 of Division 1 of Title 7. ADUs and JADUs that meet the chapter's standards receive ministerial approval (Sec. 19.81.040). On single-family lots, a detached ADU may be up to 850 sq ft (studio/one-bedroom) or 1,200 sq ft or 75% of the primary dwelling, whichever is less, for larger units (Sec. 19.81.080). Attached ADUs are limited to 50% of the primary dwelling's floor area, capped at 850 sq ft (studio/one-bedroom) or 1,000 sq ft (more than one bedroom) (Sec. 19.81.070). A JADU must be no more than 500 sq ft and contained within the single-family residence (Sec. 19.81.100). Detached ADUs are limited to 16 feet in height, rising to 18 feet within one-half mile of a major transit stop, plus up to two extra feet to match the main roof pitch; attached ADUs may reach 25 feet (Sec. 19.81.060). Side and rear setbacks are a minimum of four feet (Sec. 19.81.060). Generally one off-street parking space is required, with broad exemptions near transit or for conversions (Sec. 19.81.120). A deed restriction must be recorded before permit issuance (Sec. 19.81.130).
Building an ADU or JADU without the required permits, deed restriction, or compliance with Chapter 19.81 standards can trigger code enforcement, correction orders, and orders to obtain permits or remove unpermitted construction. Renting an ADU or JADU for periods shorter than 31 days violates Sec. 19.81.130(b).
