Simi Valley, CA Accessory Structures: ADU Rental Restrictions (2026)

160(A)(10), part of the General Provisions governing every ADU and Junior ADU (JADU) permitted under the City's ministerial ADU ordinance, states that the rental of any ADU or JADU, or the primary single-family dwelling, if the owner lives on site in the ADU or JADU, must be for periods of 30 days or more. The rule reaches three scenarios: renting out a detached or attached ADU itself, renting out a JADU, and renting out the main house when the owner has moved into the ADU or JADU and is renting the larger unit instead.

In every case, the minimum stay is 30 days, meaning the unit cannot be advertised or booked as a vacation or short-term rental. The restriction is embedded in the same section that grants ADUs streamlined, ministerial Zoning Clearance approval within 60 days of a complete application under Subsections A(3) and A(6), so a property owner who accepts that faster ADU approval path takes on the 30-day minimum rental term as one of the General Provisions attached to it. 160, regardless of the zoning district, lot size, or whether the ADU is attached, detached, or converted from an existing structure.
