Chino Hills Adu / Granny Flat Ordinance – California Accessory Dwelling Units
ORDINANCE NO.321
AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF CHINO HILLS, CALIFORNIA AMENDING TITLE 16 OF THE CHINO HILLS MUNICIPAL CODE, CHAPTER 16.02 GENERAL PROVISIONS AND DEFINITIONS, CHAPTER 16.10
RESIDENTIAL DISTRICTS, AND APPENDIX A REGULATION OF USES BY ZONING DISTRICT TO REGULATE ACCESSORY DWELLING UNITS AND GUEST HOUSES IN RESIDENTIAL ZONES AND FINDING PROPOSED MUNICIPAL CODE AMENDMENT 17MCA08 EXEMPT FROM REVIEW UNDER THE CALIFORNIA ENVIRONMENTAL QUALITY ACT
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF CHINO HILLS DOES HEREBY ORDAIN AS FOLLOWS:
SECTION 1. The City Council does hereby make the following findings of fact:
A. The City’s ability to exercise its powers in accordance with Article XI, § 7 of the California Constitution to regulate land useis well established. This Ordinance is intended to regulate aesthetics, traffic, parking, public peace, and other similar matters related to public health, safety, and welfare.
B. In 2016, the State of California enacted Senate Bill 1069 (SB 1069) and Assembly Bill 2299 (AB 2299) to encourage and facilitate the development of accessory dwelling units (ADUs) in residential zoning districts. These bills amended State law to require the ministerial approval of ADUs within a single-family residential zone, while further limiting the regulations and standards that local agencies can impose on these uses and structures. The provisions of previously adopted Ordinances addressing ADUs, including some of the City’s current second dwelling unit provisions, which do not conform to the provisions in State law became null and void as of January 1, 2017, the effective date of the bills.
State law, as amended by SB 1069 and AB 2299, allows the City to “designate areas within the jurisdiction of the local agency where accessory dwelling units may be permitted.“ The designation may be based on the impact of accessory dwelling units to traffic flow, public safety,and adequacy of utilities.
In reviewing the amendments to State law and developing the proposed standards to regulate the location and design of ADUs,the City performed a survey of existing detached single–family residential neighborhoods and existing detached single-family residential lots. Approximately 17% (3,442) of the City‘s 19,954 single-family detached residential lots are 10,000 square feet or greater. Lots of a minimum of 10,000 square feet
are considered larger lots as they provide for greater separation from adjacent detached single-family houses, greater interior yard space in
which to accommodate an ADU and to park an additional vehicle(s). Permitting attached or detached ADUs on larger lots provides greater opportunity for the development of ADUs in conformance with zoning standards, while minimizing potential adverse impacts to surrounding
properties. Properties within the City that exhibit a lot size of 10,000 square feet or greater provide a greater opportunity for attached or detached ADUs to be constructed without significant detriment to the public health, safety, and welfare. Lots of this size can provide adequate
building separation and open area to ensure sufficient natural lighting and air flow between buildings and structures. The increased lot size also provides greater opportunity to reduce potential noise and artificial light
impacts generated by the use and occupancy of ADUs. Furthermore, these lots are more able to accommodate the increased parking demand associated with the construction of new ADUs and the decreased density of areas featuring lots of this size reduce the potential for the ADUs to contribute additional traffic to areas already experiencing traffic congestion. Thus, properties with a lot size of 10,000 square feet or greater are more suitable for the construction of ADUs. The development of attached or detached ADUs on lots smaller than 10,000 square feet would be more likely to conflict with the setback, lot coverage, parking, and building separation requirements established for the protection of the public health, safety, and welfare. Additionally, smaller lots provide less opportunity for attached or detached ADUs to be located and constructed
in a way that minimizes the visual disruption to existing residential neighborhoods. ADUs within existing single-family residential structures are permitted on the remaining 83% (16,512) existing single–family detached residential lots within the City. These provisions allow for the development of ADUs on virtually every single-family detached residential lot within the City in fullcompliance with State law.
E. The Planning Commission of the City of Chino Hills held a duly noticed public hearing on September 19, 2017, opened the public hearing, and took public testimony on the project. The Planning Commission discussed the proposed Municipal Code Amendment and continued the hearing to their next meeting, directing staff to consider provisions addressing the maximum building height for ADUs, development on sloped areas,and the minimum size for accessory efficiency dwelling units.
F. Staff subsequently revised the proposed amendment to the Municipal Code regarding the regulation of ADUs and guest houses in residential zones to incorporate the Planning Commission‘s comments.
G. On October 3,2017, the Planning Commission held a duly noticed public hearing to receive oral and documentary evidence from the public
regarding the proposed amendments. The Commission discussed the revisions to the proposed amendment and adopted a resolution recommending to the City Council the adoption of the proposed Municipal Code Amendment.
H. Notice of the public hearing was published in the Chino Hills Champion newspaper on November 4, 2017.
I. A duly noticed public hearing before the City Council was conducted on November 14, 2017, at which time all interested persons were given an opportunity to testify in support of, or in opposition to the project.
SECTION 2. The City Council finds that this Ordinance is exempt from review under the California Environmental Quality Act (California Public Resources Code §§ 21000, et seq.,“CEQA”) and CEQA regulations (Title 14 California Code of Regulations
§§ 15000, et seq.) pursuant to 14 California Code Regulations § 15282{h) (Other
Statutory Exemptions) because the project consists of the adoption of an Ordinance regarding accessory dwelling unit in a single-family or multi-family residential zone by a City or County to implement the provisions of Sections 65852.1 and 65852.2 of the Government Code as set forth in Section 21080.17 of the Public Resources Code.
SECTION 3. As required under Government Code § 65860, the City Council finds that Chino Hills Municipal Code amendments proposed in Municipal Code Amendment 17MCA08 are consistent with the Chino Hills General Plan as follows:

The proposed amendment would establish development standards to ensure that ADUs do not adversely impact the residential character, aesthetic quality, or quality of life within the City‘s residential zoning district, while providing opportunity for additional development of low- and moderate–income housing.
SECTION 4. In accordance with Chino Hills Municipal Code § 16.62.040, the City Council makes the following findings of fact:
A. FINDING: That the proposed Municipal Code Amendment is consistent with the goals, policies and objectives of the General Plan.

The proposed amendment would establish development standards to ensure that ADUs do not adversely impact the residential character, aesthetic quality, or quality of life within the City’s residential zoning district, while providing opportunity for additional development of low- and moderate-income housing.
B. FINDING: That the proposed Municipal Code Amendment will not adversely affect surrounding properties.
FACT: That proposed Municipal Code Amendment would be effective in single–family residentialzoning districts throughout the City.The Municipal Code Amendment establishes reasonable standards to regulate the size and location of ADUs, Including the 10,000–square foot minimum lot size for attached or detached ADUs,to preserve the health,safety, and welfare of the community and ensure surrounding properties are not adversely affected .
