Classes. 1. Class 1: Statutorily Regulated. Class 1 ADUs and JADUs are approved under Government Code Section 66323. If an ADU or JADU complies with each of the general requirements in Section 17.28.050, it is allowed in each of the scenarios provided in this subsection (B)(1). An ADU and JADU approved under subsection (B)(1)(a) may be combined with an ADU approved under subsection (B)(1)(b), and ADUs approved under subsection (B)(1)(c) may be combined with ADUs approved under subsection (B)(1)(d).

Except for Class 1 ADUs approved under subsection (B)(1) above, all ADUs are subject to the standards set forth in Sections 17.28.050 and 17.28.060 below. 17.28.050 General ADU and JADU requirements. The following requirements apply to all Class 1 and Class 2 ADUs and: A. Zoning. 1. A Class 1 ADU approved under subsection 17.28.040(B)(1) may be created on a lot in a residential or mixed-use zone. Ordinance No. 388 ADU Amendments - 9 - 2. A Class 2 ADU approved under subsection 17.28.040(B)(2) may be created on a lot that is zoned to allow single-family dwelling residential use or multifamily dwelling residential use. 3. In accordance with Government Code Section 66333(a), a JADU may only be created on a lot zoned for single-family residences. B. Height. 1. Except as otherwise provided by subsections (B)(2) and (B)(3) below, a detached ADU created on a lot with an existing or proposed single family or multifamily dwelling unit may not exceed sixteen feet in height. 2. A detached ADU may be up to eighteen 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 high quality transit corridor, as those terms are defined in Section 21155 of the Public Resources Code, and the ADU may be up to two additional feet in height (for a maximum of twenty feet) if necessary to accommodate a roof pitch on the ADU that is aligned with the roof pitch of the primary dwelling unit. 3. 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 eighteen feet in height. 4. An ADU that is attached to the primary dwelling may not exceed twenty-five 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 subject to this subsection (B)(4) may not exceed two stories. 5. For purposes of this subsection (B), height is measured from existing legal grade or the level of the lowest floor, whichever is lower, to the peak of the structure. C. Fire Sprinklers. 1. Fire sprinklers are required in an ADU or JADU if sprinklers are required in the primary residence. 2. The construction of an ADU or JADU does not trigger a requirement for fire sprinklers to be installed in the existing primary dwelling. D. 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. E. No Separate Conveyance. An ADU or JADU may be rented, but, except as otherwise provided in Government Code Section 66341, no ADU or JADU may be sold or otherwise conveyed separately from the lot and the primary dwelling (in the case of a single-family lot) or from the lot and all of the dwellings (in the case of a multifamily lot). F. Septic System. If the ADU or JADU will connect to an onsite wastewater-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 ten years. G. Owner Occupancy. 1. ADUs are not subject to an owner-occupancy requirement. 2. JADUs. (a) Generally. As required by state law, all 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. (b) Exceptions. The owner-occupancy requirement in this subsection (G)(2) does not apply in either of the following situations: Ordinance No. 388 ADU Amendments - 10 - (i) The JADU has separate sanitation facilities (i.e., does not share sanitation facilities with the existing primary dwelling unit structure). (ii) The property is entirely owned by another governmental agency, land trust, or housing organization. H. Deed Restriction. Prior to issuance of a certificate of occupancy for a JADU, a deed restriction must be recorded against the title of the property in the County Recorder's office and a copy filed with the Director or other City employee as determined or designated by the City Manager. The deed restriction must run with the land and bind all future owners. The form of the deed restriction will be provided by the City and must provide that: 1. The JADU may not be sold separately from the primary dwelling. 2. The JADU is restricted to the approved size and to other attributes allowed by this Chapter. 3. The deed restriction runs with the land and may be enforced against future property owners. 4. The deed restriction may be removed if the owner eliminates the 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 Director or other City employee as determined or designated by the City Manager, providing evidence that the JADU has in fact been eliminated. The Director or other City employee as determined or designated by the City Manager may then determine whether the evidence supports the claim that the JADU has been eliminated. Appeal may be taken from the Director's or other City employee as determined or designated by the City Manager determination consistent with other provisions of this code. If the JADU is not entirely physically removed, but is only eliminated by virtue of having a necessary component of an JADU removed, the remaining structure and improvements must otherwise comply with applicable provisions of this code. 5. The deed restriction is enforceable by the director or other City employee as determined or designated by the City Manager 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 JADU in violation of the recorded restrictions or abatement of the illegal unit. I. Building & Safety. 1. Must Comply with Building Code. Subject to subsection (I)(2) below, all ADUs and JADUs must comply with all local building code requirements. 2. No Change of Occupancy. Construction of an ADU does not constitute a Group R occupancy change under the local building code, as described in Section 310 of the California Building Code, unless the Building Official or Code Enforcement 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 this subsection (I)(2) 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 Chapter. J. Certificate of Occupancy Timing. 1. Generally. No certificate of occupancy for an ADU or JADU may be issued before the certificate of occupancy is issued for the primary dwelling unit. 2. Limited Exception for State-declared Emergencies. Notwithstanding subsection (J)(1) 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: (a) The county is subject to a proclamation of a state of emergency made by the California Governor on or after February 1, 2025. Ordinance No. 388 ADU Amendments - 11 - (b) The primary dwelling was substantially damaged or destroyed by an event referenced in the Governor’s state of emergency proclamation. (c) The ADU has been issued construction permits and has passed all required inspections. (d) The ADU is not attached to the primary dwelling. 17.28.060 Specific ADU requirements. The following requirements apply only to Class 2 ADUs approved under subsection 17.28.040(B)(2) above: A. Maximum Size. 1. The maximum size of a detached or attached ADU subject to this Section 17.28.060 is 850 square feet of interior livable space for a studio or one-bedroom unit and 1,000 square feet for a unit of interior livable space with two or more bedrooms. 2. An attached ADU that is created on a lot with an existing primary dwelling is further limited to 50 percent of the floor area of the existing primary dwelling. 3. Application of other development standards in this Section 17.28.060, such as FAR or lot coverage, might further limit the size of the ADU, but no application of the percent-based size limit in subsection (A)(2) above or of an FAR, front setback, lot coverage limit, or open-space requirement may require the ADU to be less than 800 square feet. B. Floor Area Ratio (FAR). No ADU subject to this Section 17.28.060 may cause the total FAR of the lot to exceed 45 percent, subject to subsection (A)(3) above. C. Setbacks. 1. ADUs that are subject to this Section 17.28.060 must conform to four-foot side and rear setbacks. 2. ADUs that are subject to this Section 17.28.060 must conform to 30-foot front setbacks, subject to subsection (A)(3) above. 3.

No ADU subject to this Section 17.28.060 may cause the total lot coverage of the lot to exceed 50 percent, subject to subsection (A)(3) above. E. Minimum Open Space. No ADU subject to this Section 17.28.060 may cause the total percentage of open space of the lot to fall below 50 percent, subject to subsection (A)(3) above. F. Passageway. No passageway, as defined by Section 17.28.030(I) above, is required for an ADU. G. Parking. 1. Generally. One off-street parking space is required for each ADU or bedroom, whichever is less. The parking space may be provided in setback areas or as tandem parking, as defined by subsection 17.28.030(L). 2. Exceptions. No parking under subsection (G)(1) is required in the following situations: (a) The ADU is located within one-half mile walking distance of public transit, as defined in Section 17.28.030(K). (b) The ADU is located within an architecturally and historically significant historic district. (c) The ADU is part of the proposed or existing primary residence or an accessory structure. (d) When on-street parking permits are required but not offered to the occupant of the ADU. Ordinance No. 388 ADU Amendments - 12 - (e) When there is an established car share vehicle stop located within one block of the ADU. (f) When the permit application to create an ADU is submitted with an application to create a new single-family or new multifamily dwelling on the same lot, provided that the ADU or the lot satisfies any other criteria listed in subsections (G)(2)(a) through (e) above. 3. No Replacement. When a garage, carport, covered parking structure, or uncovered parking space is demolished in conjunction with the construction of an ADU or converted to an ADU, those off-street parking spaces are not required to be replaced. H. Architectural Requirements. 1. The materials and colors of the exterior walls, roof, and windows and doors must be the same as those of the primary dwelling. 2. The roof slope must match that of the dominant roof slope of the primary dwelling. The dominant roof slope is the slope shared by the largest portion of the roof. 3. The exterior lighting must be limited to down-lights or as otherwise required by the building or fire code. 4. The ADU must have an independent exterior entrance, apart from that of the primary dwelling. 5. The interior horizontal dimensions of an ADU must be at least ten feet wide in every direction, with a minimum interior wall height of seven feet. 6. No window or door of the ADU may have a direct line of sight to an adjoining residential property. Each window and door must either be located where there is no direct line of sight or screened using fencing, landscaping, or privacy glass to prevent a direct line of sight. 7. All windows and doors in an ADU less than thirty feet from a property line that is not a public right-of- way line must either be (for windows) clerestory with the bottom of the glass at least six feet above the finished floor, or (for windows and for doors) utilize frosted or obscure glass. I. Historical Protections. An ADU that is on or within six hundred feet of real property that is listed in the California Register of Historic Resources must be located so as to not be visible from any public right-of-way. J. Allowed Stories. No ADU subject to this Section 17.28.060 may have more than one story, except that an ADU that is attached to the primary dwelling may have the stories allowed under subsection 17.28.050(B)(4). 17.28.070 Fees. The following requirements apply to all Class 1 ADUs and JADUs and Class 2 ADUs that are approved under subsections 17.28.040(B)(1) or 17.28.040(B)(2) above. A. Impact Fees. 1. No impact fee is required for a JADU or for an ADU that is less than 750 square feet of interior livable space in size. For purposes of this subsection (A), "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. 2. 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. 3. Any impact fee that is required for an ADU that has 750 square feet or more of interior livable space must be charged proportionately in relation to the square footage of the primary dwelling unit. (E.g., the floor area of the ADU, divided by the floor area of the primary dwelling, times the typical fee amount charged for a new dwelling.) Ordinance No. 388 ADU Amendments - 13 - B. Utility Fees. 1. If an ADU or JADU is constructed with a new single-family home, a separate utility connection directly between the ADU or JADU and the utility and payment of the normal connection fee and capacity charge for a new dwelling are required. 2. Except as described in subsection (B)(1), JADUs and converted ADUs on a single-family lot that are created under subsection (B)(1)(a) are not required to have a new or separate utility connection directly between the JADU or ADU and the utility. Nor is a connection fee or capacity charge required. Notwithstanding the rest of this paragraph, a direct utility connection is required for separate conveyance of an ADU when separate conveyance is allowed under this code. 3. Except as described in subsection (B)(1), all ADUs that are not covered by subsection (B)(2), require a new, separate utility connection directly between the ADU and the utility for any utility that is provided by the City. All utilities that are not provided by the City are subject to the connection and fee requirements of the utility provider. (a) 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 (DFU) values, as defined by the Uniform Plumbing Code, upon the water or sewer system. (b) The portion of the fee or charge that is charged by the City may not exceed the reasonable cost of providing this service. 17.28.080 Nonconforming zoning code conditions, building code violations, and unpermitted structures. A. Generally. 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. B. Unpermitted ADUs and JADUs constructed before 2020. 1. Permit to Legalize. As required by state law, the City may not deny a permit to legalize an existing but unpermitted ADU or JADU that was constructed before January 1, 2020, if denial is based on either of the following grounds: (a) The ADU or JADU violates applicable building standards, or (b) The ADU or JADU does not comply with state ADU or JADU law or this ADU ordinance (Chapter 17.28). 2. Exceptions: (a) Notwithstanding subsection (B)(1), the City may deny a permit to legalize an existing but unpermitted ADU or JADU that was constructed before January 1, 2020, if the City makes a finding that correcting a violation is necessary to comply with the standards specified in California Health and Safety Code Section 17920.3.
