Rohnert Park, CA Accessory Structures: ADU Rental Restrictions (2026)

040(J) is a single, direct sentence: no ADU or JADU shall be rented for a period of fewer than thirty consecutive days. It sits at the end of the city's comprehensive ADU and JADU regulations, after the design, height, parking and fee standards in the same section, and applies to every accessory dwelling unit and junior accessory dwelling unit in the city regardless of zoning district or when it was built. 230(D), which separately prohibits short-term rentals in accessory dwelling units and accessory structures altogether; together the two sections mean an ADU cannot be advertised on a nightly or weekly basis under either the short-term rental permit process or as an unregulated month-to-month unit dressed up as a vacation stay.

The same thirty-day floor appears again inside the JADU-specific provisions at subsection (F)(6)(4), which restates that no JADU may be rented for fewer than thirty consecutive days as part of the recorded deed restriction package required before a JADU with shared sanitary facilities receives its certificate of occupancy. Because the restriction is written into the zoning code rather than only the short-term rental chapter, it applies even to an ADU host who never sought a short-term rental administrative use permit at all: renting an ADU for a week is an unpermitted use of the property under Title 17, not merely an unlicensed short-term rental.
