Carlsbad FAQ
Can I list my Carlsbad ADU on Airbnb?
No. Any ADU permitted on or after January 1, 2020 carries a recorded deed restriction prohibiting rentals shorter than 30 days. Carlsbad's STR ordinance (CMC 5.60) also categorically excludes ADUs from the short-term rental permit program.
What's the minimum lease term for a Carlsbad ADU?
30 days. Government Code 65852.2(a)(6) and CMC 21.10.030 require a 30-day or longer rental term for any ADU permitted in Carlsbad on or after January 1, 2020. Long-term tenants, monthly rentals, and family living arrangements are all permitted.
What happens if I rent my ADU on Vrbo anyway?
Carlsbad enforces CMC 5.60 with administrative citations of up to $1,000 per day, deed-restriction enforcement, and revocation of the Certificate of Occupancy. The city also reports unpermitted listings to Airbnb and Vrbo for removal.
El Cajon FAQ
Can I rent my El Cajon ADU on Airbnb?
No. California Gov. Code §65852.2(a)(7) and ECMC Title 17 require ADU rentals to be 30 days or longer. Short-term rental of an ADU is not permitted, and the El Cajon Code Compliance Division can cite ADU short-term listings.
Does my El Cajon long-term ADU rental need a city permit?
No separate permit is required for rentals of 30 days or more. Standard California landlord-tenant law applies, including the Tenant Protection Act of 2019 (AB 1482) where the property qualifies. Rent should be reported as income.
