§ 9-5.101 Designation of Residential Zones.

[Ord. 672]
(a) 
LD Low Density Residential and Low Intensity Recreational.
(b)

(c) 
HD Multiple Residential - High Density.
(d) 
L/M Low and Moderate Income Housing.

§ 9-5.102 Intent and Purpose.

[Ord. 672]
The residential zones are established to provide residential districts of varying population densities that are compatible within each category for the purpose of family living permitted therein, and including the necessary appurtenant and accessory facilities and uses associated with such living areas.

§ 9-5.103 Inclusionary Requirements.

[Ord. 672]
Any residential tract development of greater than four units developed in LD, MD and HD zones shall be subject to the low and moderate income housing requirements of Chapter 9-11.

§ 9-5.201 Intent and Purpose.

[Ord. 672]
The intent of the LD zone is to provide a framework to guide and control the development of the sloping, undeveloped areas surrounding the urbanized areas of Avalon. Currently, the land is very sparsely developed with residential structures. There is a high degree of public interest in this area because of the visual quality that these perimeter slopes contribute to the overall ambience of the City. Thus, regulation is intended to minimize grading and landform alteration.
In reviewing and approving site plans and tract maps for the development of the area, the City Planning Commission shall be guided by the goals and policies of the General Plan, and the General Development and Use Standards specified herein. The Commission shall not permit variance from those standards unless it finds that such variance meets the intent of the original standards.
Finally, it is intended that the LD zone will lead to the creation of an area exhibiting the following characteristics:
(a) 
Residential uses of various densities.
(b) 
Low intensity recreational uses which will increase available recreational opportunities to the public.

§ 9-5.202 Principal Uses Permitted.

[Ord. 672]
(a) 
Detached residential structures on slopes under 30°.
(b) 
Outdoor recreation including, but not limited to, parks and other areas of passive recreational usage, trails, and other suitable corridors open to the public and areas for the preservation of outstanding scenic, geologic, historical and cultural value.
(c) 
The preservation of natural resources, including, but not limited to, areas required for preservation of plant and animal life.
(d) 
Small and large daycare facilities, as those terms are defined by Health and Safety Code section 1596.78 and as may be amended from time to time.
[Added by Ord. No. 1203-21, eff. January 6, 2022]

§ 9-5.203 Accessory Uses Permitted.

[Ord. 672]

Accessory buildings or structures, including private garages.
(b) 
Domestic animals, not to exceed three over three months old.

b. 
The peak height above grade does not exceed the applicable height limit provided in subsection 9-5.605(b) below.
(b) 
ADU Permit.
(1) 
Except as allowed under subsection 9-5.604(a) above, no ADU may be created without a building permit and an ADU permit in compliance with the standards set forth in subsections 9-5.605 and 9-5.606 below.
(2) 
The City may charge a fee to reimburse it for costs incurred in processing ADU permits, including the costs of adopting or amending the City's ADU ordinance. The ADU-permit processing fee is determined by the Director of Community Development and approved by the City Council by resolution.
(c) 
Process and Timing.
(1) 
An ADU permit is considered and approved ministerially, without discretionary review or a hearing.
(2) 
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:
a. 
The applicant requests a delay, in which case the 60-day time period is tolled for the period of the requested delay, or
b. 
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.
(3) 
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 9-5.604(c)(2) above.
(4) 
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.

§ 9-5.605 General ADU and JADU Requirements.

[Ord. No. 1173-19, effective 3-21-2019; amended 3-2-2020 by Ord. No. 1185-20, effective 4-1-2020; 3-2-2021 by Ord. No. 1194-21, effective 4-1-2021; 1-17-2023 by Ord. No. 1210-23, effective February 16, 2023]
The following requirements apply to all ADUs and JADUs that are approved under subsections 9-5.604(a) or 9-5.604(b) above:
(a) 
Zoning.
(1) 
An ADU or JADU subject only to a building permit under subsection 9-604(a) above may be created on a lot in a residential or mixed-use zone.
(2) 
An ADU or JADU subject to an ADU permit under subsection 9-5.604(b) above may be created on a lot that is zoned to allow single-family dwelling residential use or multifamily dwelling residential use.
(b) 
Height.
(1) 
Except as otherwise provided by subsections 9-5.605(b)(2) and 9-5.605(b)(3) 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.
(2) 
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 Section 21155 of the Public Resources Code, 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.
(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 18 feet in height.
(4) 
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 9-5.605(b)(4) may not exceed two stories.
(5) 
For purposes of this subsection 9-5.605(b), height is measured above existing legal grade to the peak of the structure.
(c) 
Fire Sprinklers.
(1) 
Fire sprinklers are required in an ADU if sprinklers are required in the primary residence.
(2) 
The construction of an ADU 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 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).
(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 10 years.
(g) 
Owner Occupancy.
(1) 
An ADU that is permitted after January 1, 2020, but before January 1, 2025, is not subject to any owner-occupancy requirement.
(2) 
Unless applicable law requires otherwise, all ADUs that are permitted on or after January 1, 2025 are subject to an owner-occupancy requirement. A natural person with legal or equitable title to the property must reside on the property as the person's legal domicile and permanent residence.
(3) 
As required by state law, all JADUs are 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 9-5.605(g)(3) does not apply if the property is entirely owned by another governmental agency, land trust, or housing organization.
(h) 
Deed Restriction. Prior to issuance of a building permit for an ADU or 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 their designee) and 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:
(1) 
Except as otherwise provided in Government Code Section 65852.26, the ADU or JADU may not be sold separately from the primary dwelling.
(2) 
The ADU or JADU is restricted to the approved size and to other attributes allowed by this section.
(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 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 Director, providing evidence that the ADU or JADU has in fact been eliminated. The Director may then determine whether the evidence supports the claim that the ADU or JADU has been eliminated. Appeal may be taken from the Director's determination consistent with other provisions of this Code. 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.
(5) 
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 ADU or JADU in violation of the recorded restrictions or abatement of the illegal unit.
(i) 
Income Reporting. In order to facilitate the City's obligation to identify adequate sites for housing in accordance with Government Code sections 65583.1 and 65852.2, the following requirements must be satisfied:
(1) 
With the building-permit application, the applicant must provide the City with an estimate of the projected annualized rent that will be charged for the ADU or JADU.
(2) 
Within 90 days after each yearly anniversary of the issuance of the building permit, the owner must report the actual rent charged for the ADU or JADU during the prior year. If the City does not receive the report within the 90-day period, the owner is in violation of this Code, and the City may send the owner a notice of violation and allow the owner another 30 days to submit the report. If the owner fails to submit the report within the 30-day period, the City may enforce this provision in accordance with applicable law.
(j) 
Building & Safety.
(1) 
Must comply with building code. Subject to subsection 9-5.605(j)(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 9-5.605(j)(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 section.

No impact fee is required for an ADU that is less than 750 square feet in size. For purposes of this subsection 9-5.607(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) 
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.)
(b) 
Utility Fees.
(1) 
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.
(2) 
Except as described in subsection 9-5.607(b)(1), converted ADUs on a single-family lot that are created under subsection 9-5.607(a)(1) 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.
(3) 
Except as described in subsection 9-5.607(b)(1), all ADUs that are not covered by subsection 9-5.607(b)(2) require a new, separate utility connection directly between the ADU and the utility.
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.

Unpermitted ADUs constructed before 2018.
(1) 
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:
a. 
The ADU violates applicable building standards, or
b. 
The ADU does not comply with the state ADU law (Government Code section 65852.2) or this ADU ordinance (AMC 9-5.6).
(2) 
Exceptions:
a.

The City may conduct its own inquiries and investigation to ascertain the veracity of the sworn statement, including but not limited to, surveying owners of nearby properties; and the City may require additional evidence of the applicant and owner as necessary to determine compliance with this requirement.
(6) 
Unit Standards.
a. 
Quantity.
1. 
No more than two dwelling units of any kind may be built on a lot that results from an urban lot split. For purposes of this paragraph, "unit" means any dwelling unit, including, but not limited to, a primary dwelling unit, a unit created under this section of this code, an ADU, or a JADU.
2. 
A lot that is not created by an urban lot split may have a two-unit project under this section, plus any ADU or JADU that must be allowed under state law and the City's ADU ordinance.
b. 
Unit Size.
1. 
The total floor area of each primary dwelling built that is developed under this section must be:
A. 
Less than or equal to 800 square feet; and
B. 
More than 500 square feet.
2. 
A primary dwelling that was legally established on the lot prior to the two-unit project and that is larger than 800 square feet is limited to the lawful floor area at the time of the two-unit project. The unit may not be expanded.
3. 
A primary dwelling that was legally established prior to the two-unit project and that is smaller than 800 square feet may be expanded to 800 square feet after or as part of the two-unit project.
c. 
Height Restrictions. New primary dwelling units are governed by the height restriction imposed by the underlying zone. This height restriction shall yield to the degree necessary to avoid physically precluding the construction of up to two units on the lot or either of the two units from being at least 800 square feet in floor area.
d. 
Demo Cap. The two-unit project may not involve the demolition of more than 25 percent of the existing exterior walls of an existing dwelling unless the site has not been occupied by a tenant in the last three years.
e. 
Setbacks.
1. 
Generally. All setbacks must conform to those objective setbacks that are imposed through the underlying zone.
2. 
Exceptions. Notwithstanding subparagraph (e)(6)e above:
A. 
Existing Structures. No setback is required for an existing legally established structure or for a new structure that is constructed in the same location and to the same dimensions as an existing legally established structure.
B. 
800 sf; four-foot side and rear. The setbacks imposed by the underlying zone must yield to the degree necessary to avoid physically precluding the construction of up to two units on the lot or either of the two units from being at least 800 square feet in floor area; but in no event may any structure be less than four feet from a side or rear property line.
3. 
Front Setback Area. Notwithstanding any other part of this code, dwellings that are constructed under this section must be at least 10 feet from the front property lines. The front setback area must:
A. 
Be kept free from all structures greater than three feet high;
B. 
Be at least 50 percent landscaped with drought-tolerant plants, with vegetation and irrigation plans approved by a licensed landscape architect;
C. 
Allow for vehicular and fire-safety access to the front structure.
f. 
Parking. Each new primary dwelling unit must have at least one off-street parking space per unit unless one of the following applies:
1. 
The lot is located within one-half mile walking distance of either:
A. 
A corridor with fixed route bus service with service intervals no longer than 15 minutes during peak commute hours or
B. 
A site that contains:
(AA) 
An existing rail or bus rapid transit station;
(BB) 
A ferry terminal served by either a bus or rail transit service; or
(CC) 
The intersection of two or more major bus routes with a frequency of service interval of 15 minutes or less during the morning and afternoon peak commute periods.
2. 
The site is located within one block of a car-share vehicle location.
g. 
Architecture.
1. 
If there is a legal primary dwelling on the lot that was established before the two-unit project, any new primary dwelling unit must match the existing primary dwelling unit in exterior materials, color, and dominant roof pitch. The dominant roof slope is the slope shared by the largest portion of the roof.
2. 
If there is no legal primary dwelling on the lot before the two-unit project, and if two primary dwellings are developed on the lot, the dwellings must match each other in exterior materials, color, and dominant roof pitch. The dominant roof slope is the slope shared by the largest portion of the roof.
3. 
All exterior lighting must be limited to down-lights.
h. 
Landscaping. Evergreen landscape screening must be planted and maintained between each dwelling and adjacent lots (but not rights of way) as follows:
1. 
At least one 15-gallon size plant shall be provided for every five linear feet of exterior wall. Alternatively, at least one 24-inch box size plant shall be provided for every ten linear feet of exterior wall.
2. 
Plant specimens must be at least six feet tall when installed. As an alternative, a solid fence of at least six feet in height may be installed.
3. 
All landscaping must be drought-tolerant.
i. 
Utilities.
1. 
Each primary dwelling unit on the lot must have its own direct utility connection to the utility service provider.
2. 
Notwithstanding subparagraph (e)(6)i1 above, a primary dwelling unit may have a direct utility connection to an onsite wastewater treatment system in accordance with this paragraph and the City's Code. Each primary dwelling unit on the lot that is or that is proposed to be connected to an onsite wastewater treatment system must first have a percolation test completed within the last five years or, if the percolation test has been recertified, within the last 10 years.
3. 
All utilities must be underground.
j. 
Building & Safety. All structures built on the lot must comply with all current local building standards. A project under this section is a change of use and subjects the whole of the lot, and all structures, to the City's current code.
(7) 
Fire-Hazard Mitigation Measures.
a. 
A lot in a very high fire hazard severity zone must comply with each of the following fire-hazard mitigation measures:
1. 
It must have direct access to a public street right-of-way with a paved street with a width of at least 20 feet. The public street right-of-way must have at least two independent points of access for fire and life safety to access and for residents to evacuate.
2. 
All dwellings on the site must comply with current fire code requirements for dwellings in a very high fire hazard severity zone.
3. 
All enclosed structures on the site must have fire sprinklers.
4. 
All sides of all dwellings on the site must be within a 150-foot hose-pull distance from either the public street right-of-way or of an onsite fire hydrant or standpipe.
5. 
If the lot does not have a swimming pool, the lot must have a water reservoir of at least 5,000 gallons per dwelling, with fire-authority approved hookups compatible with fire-authority standard pump and hose equipment.
b. 
Prior to submitting an application for an urban lot split, the applicant must obtain a certificate of compliance with all applicable fire-hazard mitigation measures in accordance with this subpart (e)(7). The City or its authorized agent must inspect the site, including all structures on the site, and certify as to its compliance. The certificate must be included with the application. The applicant must pay the City's costs for inspection. Failure to pay is grounds for denying the application.
(8) 
Separate Conveyance.
a. 
Primary dwelling units on the lot may not be owned or conveyed separately from each other.
b. 
Condominium airspace divisions and common interest developments are not permitted within the lot.
c. 
All fee interest in the lot and all the dwellings must be held equally and undivided by all individual property owners.
1. 
No timeshare, as defined by state law or this Code, is permitted. This includes any co-ownership arrangement that gives an owner the right to exclusive use of the property for a defined period or periods of time.
(9) 
Regulation of Uses.
a. 
Residential-only. No non-residential use is permitted on the lot.
b. 
No STRs. No dwelling unit on the lot may be rented for a period of less than 30 days.
c. 
Owner Occupancy. Unless the lot was formed by an urban lot split, the individual property owners of a lot with a two-unit project must occupy one of the dwellings on the lot as the owners' principal residence and legal domicile.
(10) 
Notice of Construction.
a. 
At least 30 business days before starting any construction of a two-unit project, the property owner must give written notice to all the owners of record of each of the adjacent residential parcels, which notice must include the following information:
1. 
Notice that construction has been authorized,
2. 
The anticipated start and end dates for construction,
3. 
The hours of construction,
4. 
Contact information for the project manager (for construction-related complaints), and
5. 
Contact information for the Building & Safety Department.
b. 
This notice requirement does not confer a right on the noticed persons or on anyone else to comment on the project before permits are issued. Approval is ministerial. Under state law, the City has no discretion in approving or denying a particular project under this section. This notice requirement is purely to promote neighborhood awareness and expectation.
(11) 
Deed Restriction. The owner must record a deed restriction, on a form approved by the City, that does each of the following:
a. 
Expressly prohibits any rental of any dwelling on the property for a period of less than 30 days.
b. 
Expressly prohibits any non-residential use of the lot.
c. 
Expressly prohibits any separate conveyance of a primary dwelling on the property, any separate fee interest, and any common interest development within the lot.
d. 
If the lot does not undergo an urban lot split: Expressly requires the individual property owners to live in one of the dwelling units on the lot as the owners' primary residence and legal domicile.
e. 
Limits development of the lot to residential units that comply with the requirements of this section, except as required by state law.
(f) 
Specific Adverse Impacts.
(1) 
Notwithstanding anything else in this section, the City may deny an application for a two- unit project if the building official makes a written finding, based on a preponderance of the evidence, that the project would have a "specific, adverse impact" on either public health and safety or on the physical environment and for which there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact.
(2) 
"Specific adverse impact" has the same meaning as in Gov. Code § 65589.5(d)(2): "a significant, quantifiable, direct, and unavoidable impact, based on objective, identified written public health or safety standards, policies, or conditions as they existed on the date the application was deemed complete" and does not include (1) inconsistency with the zoning ordinance or general plan land use designation, or (2) the eligibility to claim a welfare exemption under Revenue and Taxation Code section 214(g).
(3) 
The building official may consult with and be assisted by planning staff and others as necessary in making a finding of specific, adverse impact.
(g) 
Coastal Regulations Apply in Full. Nothing in this section alters or lessens the effect or application of the California Coastal Act.
(h) 
Remedies. If a two-unit project violates any part of this Code or any other legal requirement:
(1) 
The buyer, grantee, or lessee of any part of the property has an action for damages or to void the deed, sale, or contract.
(2) 
The City may:
a. 
Bring an action to enjoin any attempt to sell, lease, or finance the property.
b. 
Bring an action for other legal, equitable, or summary remedy, such as declaratory and injunctive relief.
c. 
Pursue criminal prosecution, punishable by imprisonment in county jail or state prison for up to one year, by a fine of up to $10,000, or both; or a misdemeanor.
d. 
Record a notice of violation.
e. 
Withhold any or all future permits and approvals.
f. 
Pursue all other administrative, legal, or equitable remedies that are allowed by law or the city's code.
