Do the provisions of the Los Angeles Housing Code apply to a property with an ADU/JADU?
The Los Angeles Housing Code (Article I, Chapter XVI of the LAMC) applies to all residential rental properties with two or more units, including those with an ADU/JADU, where at least one unit is rented or offered for rent. If you add an ADU/JADU to a lot with an existing unit, your property falls within the scope of the Los Angeles Housing Code. For more information, visit the Los Angeles Municipal Code, Housing Code here.
What happens if my property with an ADU/JADU fails an inspection under the Los Angeles Housing Code?
If your property fails an inspection, the inspector will issue an order listing all violations. Generally, the LAHD provides 30 days to comply with the order. In some cases, an extension may be granted. If the violations are not corrected within the specified compliance period or any extensions, the case will be forwarded for enforcement.
During enforcement, a General Manager’s hearing is typically held. After considering all relevant evidence and arguments, the hearing officer may grant a continuance, refer the property for inclusion in the Rent Escrow Account Program (REAP), and/or refer the case to the City Attorney’s Office for prosecution.
