ADU Rental Restrictions: Rocklin vs Roseville
How do adu rental restrictions rules compare between Rocklin, CA and Roseville, CA?
Rocklin has fewer restrictions than Roseville.
Rocklin, CA
Placer County
Rocklin's ADU ordinance permits long-term rental of an ADU or JADU to a different party than the primary dwelling. Short-term rentals (under 30 days) of an ADU are also allowed, BUT — under RMC Chapter 17.67 — 'a short-term rental [permit] may not be issued for both a dwelling unit and accessory dwelling unit on the same parcel.' In practice, an owner must choose: STR the main house OR STR the ADU, not both. State law (Cal. Gov. Code §65852.2(a)(6)) prohibits any rental of an ADU for terms shorter than 30 days unless the local code permits it (which Rocklin partially does, subject to the dual-STR ban). Statewide rent cap and just-cause eviction protections under AB 1482 (Cal. Civ. Code §§1947.12 and 1946.2) apply to ADUs in the same way they apply to other residential rentals — single-family ADUs are typically exempt from AB 1482 if the §1947.12(d)(5) notice is given, but exemption is not automatic.

Rocklin FAQ
Can I Airbnb my ADU?
Yes, but only if you do not already have a short-term rental permit for the primary house. Rocklin's ADU chapter caps short-term rental permits at one per parcel. You also need a city STR permit and TOT registration.
Can I rent the ADU long-term to a tenant while I live in the main house?
Yes. RMC Chapter 17.67 expressly allows the primary unit and ADU to be 'rented to different parties' for long-term rentals. JADUs additionally require the owner to live on site.
Does AB 1482 rent control apply to my ADU?
It can. AB 1482 (Cal. Civ. Code §1947.12) caps rent increases at CPI + 5% (10% max). Single-family ADUs are exempt only if the owner provides the §1947.12(d)(5) notice in the lease and meets the alienability test.
Roseville FAQ
Can I rent my Roseville ADU on Airbnb?
No. California Gov. Code §65852.2(a)(7) requires ADU rentals of 30 days or more, and RMC Chapter 4.25 expressly bans short-term rental of any ADU or JADU. Even the primary dwelling on the lot cannot host an ADU STR — and new STR permits have been paused since February 13, 2023.
Does my Roseville long-term ADU rental need a permit?
No separate permit is required for rentals of 30 days or more. Standard California landlord-tenant rules apply, and the city collects no separate ADU rental license fee. AB 1482 just-cause and rent-cap rules may apply unless the ADU qualifies for the single-family exemption with the required notice.
