Deadline to approve or deny ministerial approvals. The City must approve or deny an application to create an ADU or JADU within 60 days from the date that the City receives a completed application. If the City has not approved or denied the completed application within 60 days, the application is deemed approved unless either:

1.

The applicant requests a delay, in which case the 60-day time period is tolled for the period of the requested delay, or

When an application to create an ADU or JADU is submitted with a permit application to create a new single-family or multifamily dwelling on the lot, the City may delay acting on the permit application for the ADU or JADU until the City acts on the permit application to create the new single-family or multifamily dwelling, but the application to create the ADU or JADU will still be considered ministerially without discretionary review or a hearing.

d.

Denial. If the City denies an application to create an ADU or JADU, the City must provide the applicant with comments that include, among other things, a list of all the defective or deficient items and a description of how the application may be remedied by the applicant. Notice of the denial and corresponding comments must be provided to the applicant within the 60-day time period established by subsection (d)(3)(c) above.

e.

Appeal of denial. An applicant may appeal the City's denial of the application by submitting a written appeal to the City Clerk. 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.

f.

A demolition permit for a detached garage that is to be replaced with an ADU is reviewed with the application for the ADU and issued at the same time.

(1)

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

3.

If the lot has an existing multifamily dwelling, the quantity of detached ADUs does not exceed the number of primary dwelling units on the lot.

(2)

Class 2: Locally regulated. Class 2 ADUs are approved under Government Code §§ 66314 through 66322. Except for Class 1 ADUs approved under subsection (e)(1) above, all ADUs are subject to the standards set forth in subsections (f) and (g) below.

(f)

General requirements. The following requirements apply to all ADUs and JADUs that are approved under subsection (d)(1) or (d)(2) above:

(1)

Zoning.

a.

A Class 1 ADU approved under subsection (e)(1) may be created on a lot in a residential or mixed-use zone.

b.

A Class 2 ADU approved under subsection (e)(2) above may be created on a lot that is zoned to allow single-family dwelling residential use or multi-family dwelling residential use.

In accordance with Government Code § 66333(a), a JADU may only be created on a lot zoned for single-family residences.

(2)

Height.

a.

Except as otherwise provided by subsections (f)(2)(b) and (f)(2)(c) below, a detached ADU created on a lot with an existing or proposed single-family or multi-family dwelling unit may not exceed 16 feet in height.

b.

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 multi-family 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 Public Resources Code § 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.

c.

A detached ADU created on a lot with an existing or proposed multi-family dwelling that has more than one story above grade may not exceed 18 feet in height.

d.

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 subject to this subsection (f)(2)(d) may not exceed two stories.

e.

For purposes of this subsection (f)(2), height is measured from existing legal grade to the peak of the structure.

(3)

Fire sprinklers.

a.

Fire sprinklers are required in an ADU if sprinklers are required in the primary residence.

b.

The construction of an ADU does not trigger a requirement for fire sprinklers to be installed in the existing primary dwelling.

(4)

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.

(5)

No separate conveyance. An ADU or JADU may be rented but, except as otherwise provided in Government Code § 65852.26, 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).

(6)

Septic system. If the ADU or JADU will connect to an onsite wastewater-treatment system, 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.

(7)

Owner occupancy.

a.

ADUs. ADUs created under this section on or after January 1, 2020, are not subject to an owner occupancy requirement.

b.

JADUs. As required by state law, JADUs are subject to an owner-occupancy requirement when sanitation facilities are shared with the primary dwelling on the site. JADUs with independent sanitation facilities are not 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. However, the owner-occupancy requirement in this subsection (f)(7)(b) does not apply if the property is entirely owned by another governmental agency, land trust, or housing organization.

(8)

Deed restriction. Prior to issuance of a building permit 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 planning department. 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:

a.

Except as otherwise provided in Government Code § 66341, the JADU may not be sold separately from the primary dwelling.

b.

The JADU is restricted to the approved size and to other attributes allowed by this section.

c.

The deed restriction runs with the land and may be enforced against future property owners.

d.

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, providing evidence that the JADU has in fact been eliminated. The director may then determine whether the evidence supports the claim that the JADU has been eliminated. Appeal may be taken from the director's 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 a JADU removed, the remaining structure and improvements must otherwise comply with applicable provisions of this Code.

e.

The deed restriction is enforceable by the Director or his or her 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 JADU in violation of the recorded restrictions or abatement of the illegal unit.

(9)

Reserved.

(10)

Building and safety.

a.

Must comply with building code. Subject to subsection (f)(10)(b) below, all ADUs and JADUs must comply with all local building code requirements.

b.

No change of occupancy. Construction of an ADU does not constitute a Group R occupancy change under the local building code, as described in California Building Code § 310, unless the building official or code compliance department 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 (f)(10)(b) 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.

(11)

Certificate of occupancy timing.

a.

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.

b.

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:

1.

The county is subject to a proclamation of a state of emergency made by the California Governor on or after February 1, 2025.

2.

The primary dwelling was substantially damaged or destroyed by an event referenced in the Governor's state of emergency proclamation.

3.

The ADU has been issued construction permits and has passed all required inspections.

4.

The ADU is not attached to the primary dwelling.

(g)

Specific ADU requirements. The following requirements apply only to ADUs that require an ADU permit under subsection (d)(2) above.

(1)

Maximum size.

a.

b.

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.

c.

Application of other development standards in this subsection, such as lot coverage, might further limit the size of the ADU, but no application of the percent-based size limit in subsection (g)(1)(b) 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.

(2)

Setbacks.

a.

An ADU that is subject to this subsection must conform to an 18-foot front-yard setback, subject to subsection (g)(1)(c) above.

b.

An ADU that is subject to this subsection must conform to four-foot side- and rear-yard setbacks.

c.

Exceptions. No parking under subsection (g)(4)(a) is required in the following situations:

1.

The ADU is located within one-half mile walking distance of public transit, as defined in subsection (c)(11) above.

2.

The ADU is located within an architecturally and historically significant historic district.

3.

The ADU is part of the proposed or existing primary residence or an accessory structure under subsection (d)(1)(a) above.

4.

When on-street parking permits are required but not offered to the occupant of the ADU.

5.

When there is an established car share vehicle stop located within one block of the ADU.

6.

When the permit application to create an ADU is submitted with an application to create a new single-family or new multi-family dwelling on the same lot, provided that the ADU or the lot satisfies any other criteria listed in subsections (g)(4)(b)(1) through (5) above.

c.

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.

(6)

Architectural requirements.

a.

The materials and colors of the exterior walls, roof, and windows and doors must match the appearance and architectural design of those of the primary dwelling.

b.

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.

g.

All windows and doors in an ADU are less than 30 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.

(7)

Historical protections. An ADU that is on or within 600 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.

(8)

Allowed stories. No ADU subject to this subsection may have more than one story, except that an ADU that is attached to the primary dwelling may have the stories allowed under subparagraph (f)(2)(d) of this section.

(h)

Fees. The following requirements apply to all ADUs that are approved under subsections (d)(1) or (d)(2) above.

(1)

Impact fees.

a.

No impact fee is required for an ADU that is less than 750 square feet in size. For purposes of this subsection (h)(1), "impact fee" means a "fee" under the Mitigation Fee Act (Government Code § 66000(b)) and a fee under the Quimby Act (Government Code § 66477). "Impact fee" here does not include any connection fee or capacity charge for water or sewer service.

b.

Any impact fee that is required for an ADU that is 750 square feet or larger in size 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.)

(2)

Utility fees.

a.

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.

b.

Except as described in subsection (h)(2)(a), converted ADUs on a single-family lot that are created under subsection (d)(1)(a) above 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.

c.

Except as described in subsection (h)(2)(a), all ADUs that are not covered by subsection (h)(2)(b) 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.

1.

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.

2.

The portion of the fee or charge that is charged by the City may not exceed the reasonable cost of providing this service.

(i)

Nonconforming zoning code conditions, building code violations, and unpermitted structures.

(1)

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.

(2)

Unpermitted ADUs and JADUs constructed before 2020.

a.

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:

1.

The ADU or JADU violates applicable building standards, or

2.

The ADU or JADU does not comply with the state ADU or JADU law or this ADU ordinance (Section 30-467).

b.

Exceptions.

1.

Notwithstanding subsection (i)(2)(a) above, 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 Health and Safety Code § 17920.3.

2.

Subsection (i)(2)(a) above does not apply to a building that is deemed to be substandard in accordance with California Health and Safety Code § 17920.3.
