Rocklin, CA Accessory Structures: ADU Rental Restrictions (2026)

Rocklin Municipal Code Section 17.67.040(C) governs junior accessory dwelling units (JADUs): they may not be sold separately from the primary residence, may be rented independently of the primary unit, and may not be rented for fewer than thirty consecutive calendar days. Section 17.67.040(D) applies the same rental floor to standard accessory dwelling units (ADUs), which likewise may not be rented for fewer than thirty consecutive calendar days and may not be sold separately from the primary residence, except as otherwise allowed by California law. Both provisions permit the ADU or JADU to be leased to a tenant separate from whoever occupies the primary home, so long as each rental term runs at least thirty days, which as a practical matter bars listing a Rocklin ADU or JADU on a nightly or weekly short-term rental platform.

The thirty-day floor mirrors the definition line the city's short-term rental ordinance in Chapter 5.22 draws between short-term and long-term tenancies, keeping ADU rentals out of that separate permitting and transient occupancy tax regime. For a JADU, the no-separate-sale and thirty-day rental floor are also written into the recorded owner covenant required before a building permit issues under Section 17.67.040(C)(6).
