Cure. After receiving a notice that the application is incomplete, the applicant may cure and address the items that were deemed by the city to be incomplete.
Subsequent submittals. If the applicant submits additional information to address incomplete items, within 15 business days of the subsequent submittal the city will determine in writing whether the additional information remedies all the incomplete items that the city identified in its original notice. The city may not require the application to include an item that was not included in the original notice.

The planning commission will review the written appeal and affirm or reverse the denial and provide a final written determination to the applicant within 60 business days after receipt of the appeal.
Demolition of Detached Garages. In instances where a detached garage is to be demolished and replaced by an ADU, the application for the demolition of the garage will be reviewed with the application for the ADU and the permit for the garage demolition and ADU will be issued at the same time.
General ADU and JADU Requirements. The following requirements apply to all ADUs and JADUs that are approved under Sec. 830.A.4.a. Type 1 – Building Permit Only or Sec. 830.A.4.b. Type 2 - Building Permit Only:
Zoning
An ADU or JADU subject only to a building permit under Sec. 830.A.4.a. Type 1 – Building Permit Only, may be created on a lot in a residential or mixed-use zone.
An ADU or JADU subject to a building permit under Sec. 830.A.4.b. Type 2 - Building Permit Only, may be created on a lot that is zoned to allow single unit dwelling residential use or multi-unit dwelling residential use.
Height
Except as otherwise provided by Sec. 830.A.5.b.2. and Sec. 830.A.5.b.3. General ADU and JADU Requirements, below, a detached ADU created on a lot with an existing or proposed single family or multifamily dwelling unit may not exceed 16 feet in height.
A detached ADU may be up to 18 feet in height if it is created on a lot with an existing or proposed single family or multifamily dwelling unit that is located within one-half mile walking distance of a major transit stop or a high quality transit corridor, as those terms are defined in the California Public Resources Code (Section 21155), and the ADU may be up to two additional feet in height (for a maximum of 20 feet) if necessary to accommodate a roof pitch on the ADU that is aligned with the roof pitch of the primary dwelling unit.
A detached ADU created on a lot with an existing or proposed multifamily dwelling that has more than one story above grade may not exceed 18 feet in height.
An ADU that is attached to the primary dwelling may not exceed 25 feet in height or the height limitation imposed by the underlying zone that applies to the primary dwelling, whichever is lower. Notwithstanding the foregoing, ADUs must not exceed two stories.
For purposes of this Sec. 830.A.5.b., Height is the vertical distance measured from the adjoining curb level to the highest point of the structure, exclusive of chimneys and ventilators.
Fire Sprinklers
Fire sprinklers are only required in an ADU or JADU if sprinklers are required in the primary residence. For purposes of this paragraph, in the case of multi-unit structures, the entire residential structure will be considered the primary residence.
The construction of an ADU or JADU will not trigger a requirement for fire sprinklers to be installed in the existing primary dwelling or existing multi-unit dwelling.
Rental Term. No ADU or JADU may be rented for a term that is shorter than 30 days. This prohibition applies regardless of when the ADU or JADU was created.
No Separate Conveyance. Except as otherwise provided in the California Government Code (Sec. 65852.26.), an ADU or JADU may be rented, but no ADU or JADU may be sold or otherwise conveyed separately from the lot and the primary dwelling (in the case of a single-unit lot) or from the lot and all of the dwellings (in the case of a multi-unit lot).
Septic System. If the ADU or JADU will connect to an on-site water-treatment system, the Owner must include with the application a percolation test completed within the last five years or, if the percolation test has been recertified, within the last 10 years.
Owner-Occupancy.
ADUs. ADUs are not subject to an owner-occupancy requirement.
JADUs.
Generally. As required by state law, JADUs are generally subject to an owner-occupancy requirement. A natural person with legal or equitable title to the property must reside on the property, in either the primary dwelling or JADU, as the person’s legal domicile and permanent residence.
Exceptions. The owner-occupancy requirement in this subsection does not apply in either of the following situations:
The JADU has separate sanitation facilities (i.e., does not share sanitation facilities with the existing primary dwelling unit structure).
The property is entirely owned by another governmental agency, land trust, or housing organization.
Deed Restrictions. Prior to the issuance of a certificate of occupancy for an ADU or JADU, a deed restriction must be recorded against the title of the property in the Los Angeles County Recorder's office and a copy filed with the Director of Development Services. The deed restriction must run with the land and bind all future owners.
A deed restriction or similar instrument that runs with the land, must be recorded against the property and must include the following:
Except as otherwise provided in the California Government Code Sec.66340 to 66342, the ADU or JADU may not be sold separately from the primary dwelling.
The ADU or JADU is restricted to the approved size and to other attributes allowed by this section.
The deed restriction runs with the land and may be enforced against future property owners.
The deed restriction may be removed if the owner eliminates the ADU or JADU, as evidenced by, for example, removal of the kitchen facilities.
To remove the deed restriction, an owner may make a written request of the Development Services Director, providing evidence that the ADU or JADU has in fact been eliminated.
The Director of Development Services may then determine whether the evidence supports the claim that the ADU or JADU has been eliminated.
Appeal may be taken from the Director of Development Service’s determination consistent with Sec. 1170.E. Director Determination. If the ADU or JADU is not entirely physically removed, but is only eliminated by virtue of having a necessary component of an ADU or JADU removed, the remaining structure and improvements must otherwise comply with applicable provisions of this Code.
The deed restriction is enforceable by the Development Services Director or their designee for the benefit of the City. Failure of the property owner to comply with the deed restriction may result in legal action against the property owner, and the City is authorized to obtain any remedy available to it at law or equity, including, but not limited to, obtaining an injunction enjoining the use of the ADU or JADU in violation of the recorded restrictions or abatement of the illegal unit.
Building and Safety
Must Comply with the Building Code. Subject to Sec. 830.A.5.i.2. No Change of Occupancy, below, all ADUs and JADUs must comply with all local building code requirements.
No Change of Occupancy. Construction of an ADU does not constitute a Group R occupancy change under the local building code, as described in the California Building Code (Sec. 310), unless the building official or Code Enforcement Division officer makes a written finding based on substantial evidence in the record that the construction of the ADU could have a specific, adverse impact on public health and safety. Nothing in Sec. 830.A.5.i.2. No Change of Occupancy prevents the City from changing the occupancy code of a space that was uninhabitable space or that was only permitted for nonresidential use and was subsequently converted for residential use in accordance with this section.
Specific ADU Requirements. The following requirements apply only to ADUs that require a building permit under Sec. 830.A.4.b. Type 2 - Building Permit Only, above.

A certificate of occupancy may be issued concurrently for both the Primary Dwelling Unit and the ADU.
Limited Exception for State-declared Emergencies. Notwithstanding subsection (f)(10)(A) above, a certificate of occupancy for an ADU may be issued before a certificate of occupancy for the primary dwelling if each of the following requirements are met:

For purposes of this subsection (a)(i), “impact fee” means a “fee” under the Mitigation Fee Act (Gov. Code § 66000(b)) and a fee under the Quimby Act (Gov. Code § 66477). “Impact fee” here does not include any connection fee or capacity charge for water or sewer service.
A JADU or ADU with less than 500 square feet of interior livable space does not increase assessable space by 500 square feet for purposes of Education Code section 17620(a)(1)(C), and is therefore not subject to school fees under Education Code section 17620.
Any impact fee that is required for an ADU that is 750 square feet of interior livable space or larger in area must be charged proportionately in relation to the square footage of the primary dwelling unit. (E.g., the floor area of the primary dwelling, divided by the floor area of the ADU, times the typical fee amount charged for a new dwelling).
Utility Fees and Connections
If an ADU is constructed with a new single-family home, a separate utility connection directly between the ADU and the utility and payment of the normal connection fee and capacity charge for a new dwelling are required.
With exception to Sec. 830.A.7.b.1. Utility Fees and Connections, above, converted ADUs on a single-family lot that are created under Sec. 830.A.4.a.1. Interior ADU on a Single-Unit Lot are not required to have a new or separate utility connection directly between the ADU and the utility. Nor is a connection fee or capacity charge required.
With exception to Sec. 830.A.7.b.1. Utility Fees and Connections, all ADUs that are not covered by Sec. 830.A.7.b.2. Utility Fees and Connections require a new, separate utility connection directly between the ADU and the utility.
The connection is subject to a connection fee or capacity charge that is proportionate to the burden created by the ADU based on either the floor area or the number of drainage- fixture units values, as defined by the Uniform Plumbing Code, upon the water or sewer system.
The portion of the fee or charge that is charged by the City may not exceed the reasonable cost of providing this service.
Nonconforming Code Conditions, Violations, and Permitted Structures General. The City will not deny an ADU or JADU application due to a nonconforming zoning condition, building code violation, or unpermitted structure on the lot that does not present a threat to the public health and safety and that is not affected by the construction of the ADU or JADU.
Unpermitted ADUs constructed before 2018
Permit to Legalize. As required by state law, the City may not deny a permit to legalize an existing but unpermitted ADU that was constructed before January 1, 2018, if denial is based on either of the following grounds:
The ADU violates applicable building standards; or
The ADU does not comply with the California Government Code 830.A. Accessory Dwelling Units.
Exceptions
Notwithstanding Sec. 830.A.8.b.1. Permit to Legalize, above, the City may deny a permit to legalize an existing but unpermitted ADU that was constructed before January 1, 2018, if the City makes a finding that correcting a violation is necessary to protect the health and safety of the public or of occupants of the structure.
Sec. 830.A.8.b.1. Permit to Legalize, above, does not apply to a building that is deemed to be substandard in accordance with the California Health and Safety Code (Sec. 17920.3.).
