An Accessory Dwelling Unit (ADU) is defined in the Los Angeles Municipal Code (“LAMC”) Section 12.03 as follows: An attached or detached residential dwelling unit that provides complete independent living facilities for one or more persons and is located on a lot with a proposed or existing primary residence. It shall include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same lot as the single-family or multifamily dwelling is or will be situated. ADUs include efficiency units as defined in Section 17958.1 of the Health and Safety Code, manufactured homes as defined in Section 18007 of the Health and Safety Code, and Movable Tiny Houses.

Yes, the City of Los Angeles approved ordinance # 186,481 which codified the ADUs/JADUs related information in the LAMC Section 12.22.A.33. You may also refer to the State of California Government Code Sections 65852.2 and 65852.22.
Los Angeles Housing Code
The Los Angeles Housing Code (Article I, Chapter XVI of the LAMC) apply to all residential rental properties with two or more units and where one or more of these units are rented or offered for rent. If you have added an ADU/JADU on a lot with an existing unit, the property would come within the scope of the Los Angeles Housing Code.

If your property does not pass an inspection, the inspector will issue an order which will list all violations. Generally LAHD provides 30 days to comply with the order. In some cases an inspector may grant an extension of time. However, if the violations have not been corrected by the compliance period specified on the order or any extension thereafter, the case is forwarded for enforcement.
Generally, during enforcement, a General Manager’s hearing is held. After considering all relevant evidence and arguments, the General Manager’s hearing officer may grant a continuance, refer the property for inclusion into the Rent Escrow Account Program (REAP), and/or refer the case to the City Attorney’s Office for prosecution.
Rent Stabilization Ordinance
Generally, the RSO (Article I, Chapter XV of the LAMC) applies to all residential units offered for rent in the City of Los Angeles which were built on or before October 1, 1978, unless there is only one Single Family Dwelling on the parcel. If an ADU/JADU (Junior Accessory Dwelling Unit) is added to a parcel with an existing residential structure, the ADU/JADU and/or the existing structure, may be subject to the RSO depending on when the existing structure at the property was built.
Scenario 1: ADU/JADU detached from original structure. If the ADU/JADU is completely detached from the original Pre-1978 Single Family Dwelling (SFD) structure, then the ADU/JADU is generally not subject to the RSO, but the SFD is subject to the RSO because of the construction of a second unit on the same parcel. However, the ADU/JADU could be subject to the RSO if LAMC Section 151.28 applies, regarding replacement units under the Ellis Act (California Gov’t Code Sections 7060 et seq.).
Scenario 2: ADU/JADU attached to original structure. If the ADU/JADU is attached to the Pre 1978 SFD structure, then both structures are subject to the RSO. In this instance, California Civil Code 1954.52(a)(1), aka the Costa Hawkins Act, would apply. The Costa Hawkins Act allows residential property owners to establish the initial and all subsequent rental rates for a dwelling or a unit that was issued a Certificate of Occupancy after February 1, 1995. As a result, the rent increase protections of the RSO do not apply. All other protections of the RSO remain in force, which include registration of rental units and eviction protections.
Scenario 3: If the ADU/JADU is converted from a portion (whether habitable or not) of the Pre 1978 SFD structure, then both are fully subject to the RSO.
Yes. If your property with an ADU/JADU is subject to the RSO, you will have to pay the annual RSO registration fee. The current RSO registration fee is $38.75 per unit per year. For more information visit https://housing.lacity.org/rental-property-owners/billing-fee-schedule
Rental units subject to the RSO may receive a temporary, one-year exemption from registration and SCEP fees if the units are: 1) occupied by the landlord, family members and/or where no rents are collected; or 2) held vacant for a year or longer with the units secured and the exemption is recorded against the title. Temporary exemptions requests must be submitted on a yearly basis. The renewal of temporary exemptions is due by January 31 of each year as part of the annual registration process. Additional information is available online: https://housingbill.lacity.org/billing.
That depends on whether the ADU/JADU is subject to the RSO. Home-sharing is not allowed in units subject to the RSO.
The RSO requires a reduction in rent when a housing service provided at the inception of tenancy is removed. Landlords who reduce housing services without a corresponding reduction in rent effectuate an increase in rent in violation of the RSO. When a tenant has suffered a reduction of services that are severable and specific to that tenant (i.e. loss of parking space, loss of storage, etc.), the corresponding reduction of rent may be calculated based on the reasonable replacement cost. Landlords can be proactive and issue the reduction at the time of removal of the parking. Any change to terms of tenancy requires a written notice in compliance with state law.
