--- (1) ---

Editor's note— §§ 6, 7, Ord. 825-C.S., effective November 8, 2017, repealed Art. 4.5 and enacted a new Art. 4.5 to read as set out herein. Former Art. 4.5, §§ 4.5.451—9-456, pertained the second residential units and derived from § I, Ord. 357-C.S., effective December 8, 1982; §§ I, II, Ord. 452-85, effective October 23, 1985; §§ III(A)—(C), Ord. 491-C.S., effective October 28, 1987; §§ 1—6, Ord. 584-C.S., effective February 12, 1992; and § I(A)—(F), Ord. 613-C.S., effective April 13, 1994.


Sec. 9-4.451.- Purpose.

The City Council finds and declares its intent as follows:

(a)

To enact regulations governing accessory dwelling unit and junior accessory dwelling unit construction in compliance with Section 65852.2 and Section 65852.22 of the Government Code. The provisions of this article shall be liberally construed in order to accomplish development of accessory dwelling units and junior accessory dwelling units. In the event of a conflict between the provisions of this article and any other ordinance of the City of Pacifica regulating accessory dwelling units or junior accessory dwelling units, the provisions of this article shall prevail.

(b)

To establish a process for ministerial review and approval of accessory dwelling units and junior accessory dwelling units. No local ordinance, policy, or regulation other than this article and regulations referenced therein shall be the basis for the denial or delay of a building permit for an accessory dwelling unit or junior accessory dwelling unit.

(c)

To mitigate a widespread and ongoing shortage of affordable housing within the City. The United States Census Bureau's 2013—2017 American Community Survey estimates that forty-four (44%) percent of renter households in Pacifica pay thirty (30%) percent or more of their household income for housing-related expenses. The Census Bureau considers households that pay thirty (30%) percent or more of their household income for housing-related expenses as "cost burdened";

(d)

To provide for additional housing supply without converting Pacifica's open space areas into developed sites. More than thirty (30%) percent of the City of Pacifica's twelve and six-tenths (12.6) square mile land area is preserved as permanent open space, resulting in a limited supply of developable vacant sites for the construction of new housing units in the City. Accessory dwelling unit and junior accessory dwelling unit construction, by creating new housing units within existing neighborhoods, can expand access to affordable housing while avoiding significant environmental impacts associated with traditional residential development on vacant sites;

(e)

To provide for additional affordable housing opportunities without a commitment of public funds which are usually necessary to subsidize large-scale affordable housing development projects;

(f)

To provide for convenient child care opportunities within residential neighborhoods. For working-age residents with children, accessory dwelling units allow family members or other child care providers to reside in close proximity to the household requiring child care. The nearby availability of child care for their children offers working-age residents convenience, and more importantly, may enable them to work and support their families without the burden of commercial child care costs;

(g)

To provide for convenient elder care opportunities within residential neighborhoods. Accessory dwelling units and junior accessory dwelling units enable multi-generational living on a common site. The United States Census Bureau's 2013—2017 American Community Survey estimates that thirteen (13%) percent of Pacifica's population is sixty-five (65) years or older, an increase from eleven (11%) percent in 2010. As Pacifica's population ages, accessory dwelling units and junior accessory dwelling units allow family members or other caregivers to reside in close proximity to those receiving care while affording them the privacy of their own living space. For those receiving care, accessory dwelling units and junior accessory dwelling units will enable many to remain in their homes longer than would otherwise be possible without needing to relocate to an assisted living or other facility;

(h)

To provide supplemental income opportunities to those living on fixed incomes in retirement. Accessory dwelling units and junior accessory dwelling units may provide an important source of rental income to many property owners, especially those who are retired. The United States Government Accountability Office, in its report "Retirement Security: Most Households Approaching Retirement Have Low Savings" (Report No. GAO-15-419), estimated that in 2013, fifty-two (52%) percent of households age fifty-five (55) years and older had no retirement savings in a defined contribution plan or individual retirement account, and that Social Security provides most of the retirement income for about half of households age sixty-five (65) years and older. The report also found that among the forty-eight (48%) percent of households age fifty-five (55) years and older with some retirement savings, the median amount is approximately One Hundred and no/100ths ($109,000.00) Dollars, or equivalent to an inflation-protected annuity of Four Hundred Five and no/100ths ($405.00) Dollars per month at current rates for a sixty-five-year old. The report further found that nearly thirty (30%) percent of households age fifty-five (55) years and older have neither retirement savings nor a defined benefit plan, and that Social Security is the largest component of household income in retirement, making up an average of fifty-two (52%) percent of household income for those age sixty-five (65) years and older. Based on United States Census Bureau 2013—2017 American Community Survey estimates, the median rent in Pacifica in 2017 was Two Thousand One Hundred Ten and no/100ths ($2,110.00) Dollars per month. The addition of income from the long-term rental of an accessory dwelling unit or a junior accessory dwelling unit could meaningfully strengthen the finances of retired persons or those nearing retirement;

(i)

To preserve affordable housing opportunities within accessory dwelling units and junior accessory dwelling units. An analysis of listings on the short-term rental site Airbnb in November 2019 found two hundred sixty-nine (269) accommodations listed within the City of Pacifica, sixty-two (62%) percent of which offered for rent an entire house. The average price per night for the listed accommodations was One Hundred Fifty-Seven and no/100ths ($157.00) Dollars per night, equivalent to a monthly rent of Four Thousand Seven Hundred Ten and no/100ths ($4,710.00) Dollars. According to the United States Census Bureau's 2013—2017 American Community Survey estimates, median monthly rent during 2017 was Two Thousand One Hundred Ten and no/100ths ($2,110.00) Dollars, equivalent to Seventy and 33/100ths ($70.33) Dollars per night. Even if rented fewer than thirty (30) days per month, the potential to yield significantly greater rents from short-term rentals of residential property than from long-term rental provides a strong financial incentive to remove housing from the long-term rental market in favor of offering it for rent in the short-term rental market. In order to conform to state law and preserve public health, safety, and welfare by increasing access to affordable housing, the City Council desires to impose a prohibition on the short-term rental of accessory dwelling units and junior accessory dwelling units for periods less than thirty (30) days in order to preserve their use for long-term residential occupancy.

(j)

To preserve public health and safety by prohibiting attached and detached accessory dwelling units at sites fronted by unpaved streets or streets with widths of twenty-six (26') feet or less. Appendix D of the 2016 California Fire Code, adopted by ordinance by the City Council, establishes minimum street width and construction-type standards to ensure safe access by fire apparatus. Among other standards, Appendix D requires streets to be paved with asphalt, concrete, or another approved surface capable of supporting the load of fire apparatus weighing at least seventy-five thousand (75,000) pounds. It further requires streets to be at least twenty (20') feet in width and prohibits on-street parking on streets twenty-six (26') feet or less in width. Appendix D allows on-street parking on one side of streets greater than twenty-six (26') feet but less than thirty-two (32') feet in width. In order to preserve public safety, it is necessary to prohibit attached and detached accessory dwelling unit construction on unpaved streets and on streets where Appendix D of the 2016 California Fire Code prohibits on-street parking. Such a prohibition is necessary because accessory dwelling unit construction will generate intensified demand for on-street parking. Increased demand for on-street parking may result because off-street parking facilities may be unavailable to offset the demand, and because no mechanism exists to limit the number of automobiles owned by households occupying accessory dwelling units. In particular, accessory dwelling units located within one-half (½) mile of transit generally will not have sufficient off-street parking facilities because the City is prohibited under state law from requiring off-street parking for such accessory dwelling units (see Gov. Code §§ 65852.2(d), (e)). Additionally, households occupying accessory dwelling units located elsewhere may own more vehicles than can be accommodated in the off-street parking facilities the City is permitted to require for accessory dwelling units under state law (not more than one space per bedroom or per unit, whichever is less; see Gov. Code § 65852.2(a)(1)(D)(x)(I)). Therefore, it is possible and likely that accessory dwelling unit construction on streets twenty-six (26') feet or less in width could result in increased on-street parking demand. On-street parking on streets of inadequate width has the potential to narrow or obstruct the path of travel of fire apparatus and other emergency vehicles, delaying response time and endangering public safety.

(9)

No passageway shall be required in conjunction with the construction of an accessory dwelling unit.

(10)

Any accessory dwelling unit may have an interior point of access connecting the primary dwelling unit and accessory dwelling unit provided it is possible for the occupants of both the primary dwelling unit and the accessory dwelling unit to independently secure the point of access to prevent unauthorized entry by occupants of the other dwelling unit.

(11)

A building permit shall be required to construct an accessory dwelling unit or to establish an accessory dwelling unit within the existing space of a primary dwelling unit or accessory structure. Occupancy of an accessory dwelling unit shall be prohibited until the accessory dwelling unit receives a successful final inspection pursuant to a valid building permit and receives a certificate of occupancy issued on or after the date of the successful final inspection.
