The purpose of this chapter is to establish the procedures for the development of Accessory Dwelling Units and Junior Accessory Dwelling Units on lots zoned to allow single-family or multifamily dwelling residential use and that include a proposed or existing dwelling pursuant to Government Code Sections 65852.2 and 65852.22.
(Ord. 1687 § 3, 2023)
"Accessory dwelling unit" (ADU)
means an attached, a detached, or converted 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. An ADU shall include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as the single- or multi-family dwelling is or will be situated. An ADU also includes the following: an efficiency unit as defined in Section 17958.1 of the Health and Safety Code and a manufactured home as defined in Section 18007 of the Health and Safety Code. Accessory dwelling units may be attached to the primary dwelling unit, detached from the primary dwelling unit or may involve the conversion of floor area of an existing structure.
"ADU ordinance"
means Chapter 25.17 and all objective standards applicable to ADUs contained in Title 25.
"Attached ADU"
means an ADU that is constructed as a physical expansion of the primary dwelling unit and is attached to the primary dwelling unit.
"Converted ADU"
means an ADU that is constructed within the walls of the primary dwelling unit or an existing detached structure, including conversion of an existing attached or detached garage into an ADU.
"Detached ADU"
means an ADU that is within an independent structure entirely separate from the primary dwelling unit and other accessory structures.
"Junior accessory dwelling unit" (JADU)
means a unit that is no more than 500 square feet in size and contained entirely within a single-family residence. A JADU may include separate sanitation facilities or may share sanitation facilities with the existing structure. The JADU shall include a separate entrance from the main dwelling.
"Primary dwelling"
means an existing or proposed residential structure and includes both livable and non-livable areas. Detached structures, such as a detached garage is not considered part of the primary dwelling.
"Public transit"
means a location, including but not limited to a bus stop or train station, where the public may access buses and other forms of transportation that charge set fares, run on fixed routes, and are available to the public. This definition includes Laguna Beach Transit and Trolley.
(Ord. 1687 § 3, 2023)
(A) 
Effect of Consistency. An ADU or JADU that conforms to the requirements of this chapter is:
(1) 
Deemed consistent with the allowable density for the lot upon which such unit is proposed to be established.
(2) 
Deemed consistent with the existing general plan and zoning designations for the lot.
(3) 
Not counted towards the calculation for major remodel projects, except as necessary to comply with Section 30253 of the Coastal Act limiting alterations of existing bluff top, beachfront, and coastal canyons, and to determine the applicability of Section 30235 of the Coastal Act and equivalent LCP policies.
(B) 
Exceptions to Ministerial Review. Discretionary review may be required as follows.
(1) 
Coastal Zone. ADUs that are not exempted or excluded under Chapter 25.07 (Coastal Development Permits) require issuance of a coastal development permit, subject to the noticing and appeal requirements in that chapter.
(2) 
Deviations from Objective Standards. ADU and JADU applications that deviate from the standards of this chapter may still be permitted but shall not qualify for ministerial review. Such applications shall be subject to applicable design review, variance, coastal development permit, and other entitlements pursuant to Title 25.
(C) 
Processing Time. Zoning plan check shall be required for compliance with applicable zoning regulations and applicable building and construction requirements set forth in Titles 14 (Buildings and Construction) and 17 (Sewers).
(1) 
Ministerial Review Time. Except as set forth in paragraph (2) below, applications must be approved or denied within 60 days from the date the city receives a completed application if there is an existing single-family or multifamily dwelling on the lot, or the application shall be deemed approved. Where an application deviates from the objective standards of this chapter, the application may be reviewed pursuant to the procedures of Section 25.17.030(B)(2) (Deviations).
(2) 
If the applicant requests a delay, the 60-day period shall be tolled for the period of the delay.
(3) 
Exception to Review Time. If the permit application to create a purely ministerial ADU or JADU is submitted with an application to construct a new dwelling, the following shall apply:
(a) 
The ADU or JADU shall not be subject to the 60-day approval period but shall instead be subject to the approval period for the new dwelling. However, the ADU or JADU itself shall be considered without a public hearing.
(b) 
An ADU or JADU may only be constructed concurrently with or after the construction of a new dwelling unit on the same lot. A certificate of occupancy for an ADU shall not be issued prior to the certificate of occupancy for the new primary dwelling unit.
(4) 
If the city denies an application for an ADU or JADU, it shall provide a full set of comments with the denial listing the items that are defective or deficient and shall describe how the application can be remedied by the applicant.
(5) 
The City shall not deny a permit to an unpermitted ADU or JADU that was constructed before January 1, 2018 due to violations of building standards or this chapter provided that correction of the violation is not necessary to protect the health and safety of the public or the occupants of the structure. This provision shall not apply to substandard buildings.
(D) 
Precedence in Provisions. Applications shall comply with the objective standards outlined in this chapter and the zoning district in which the ADU or JADU is located. In the event of a conflict between the development standards set forth in the zone and the standards of this chapter, the provisions of this chapter shall take precedence.
