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

37 (Accessory Dwelling Units) cannot be used as one, regardless of who owns or occupies it. The prohibition also independently reaches any dwelling unit, ADU or otherwise, that carries a recorded covenant specifically barring rentals of 30 days or less; such covenants are common where an ADU was approved under a deed restriction tied to state ADU law. Because California's Government Code sections 66310 through 66342 preempt cities from imposing local restrictions on ADUs that conflict with state law, Upland's ban is framed narrowly as a short-term rental use restriction under the city's short-term rental chapter, rather than as a general limit on renting an ADU: a homeowner can still rent an ADU as a long-term tenancy of more than 30 days, which state ADU law protects, but cannot list that same unit as a nightly or weekly short-term rental.

090(B), which already confines a host's short-term rental permit to the main dwelling unit that is the host's primary residence, so an ADU on that same parcel is doubly excluded.
