Editor's note— Ord. No. 296, § 3(Exh. A), adopted April 14, 2021, repealed the former Ch. 8.124., §§ 8.124.010, 8.124.030—8.124.160, and enacted a new Ch. 8.124 as set out herein. The former Ch. 8.124 pertained to similar subject matter and derived from Ord. No. 195, adopted 2003; Ord. No. 274, adopted Feb. 14, 2018; Ord. No. 293, § 3(Exh. A), adopted November 10, 2020.
This chapter provides for the creation of accessory dwelling units (ADUs) and junior accessory dwelling units (JADUs) in the town as required by state law, and in accordance with the Town's General Plan and Housing Element as a means to provide a variety of housing types to meet the town's projected housing needs. This chapter provides for the ministerial approval of ADUs and JADUs in areas zoned to allow residential uses. The Town encourages ministerial review of ADUs and JADUs when possible. This Ordinance also provides procedures and standards for review of accessory dwelling units that do not meet the ministerial requirements as set forth herein that are intended to increase opportunities for ADUs to be developed within the Town.

(Ord. No. 296, § 3, 4-14-2021)
The purpose of this article is to provide procedures and standards for the review and approval of ADUs that do not meet one or more of the development and/or design standards set forth in Sections 8.124.130 and 8.124.140, respectively. The intent of these procedures is to reasonably allow such units to be established, subject to administrative adjustment or discretionary review, even when they would not qualify for ministerial review and approval pursuant to the requirements of state law, thereby increasing the opportunities for ADUs to be developed in the town.
(Ord. No. 296, § 3, 4-14-2021)
This article is only applicable to provide alternative processes to the statutory requirements for ministerial review, and to thereby provide for minor administrative adjustments and a system of discretionary review in a manner designed to increase opportunities for ADUs to be developed in the town beyond that which is required by state law. In no event shall this article be interpreted to expand or otherwise amend the requirements for ministerial review set forth in Article 3.
(Ord. No. 296, § 3, 4-14-2021)
A.
Allowable Adjustments. The planning director may approve a minor adjustment to the development or design standards applicable to an application for an attached or detached standard ADU governed by Article 3, to the extent identified in Table 8.124-1. Only a maximum of two of the allowable adjustments may be granted for such an ADU per parcel. A request for more than two adjustments or that exceeds the adjustment limitations identified in Table 8.124-1 may not be reviewed under Article 3, governing ministerial review, and this Section 8.124.170 and shall require an application for a conditional use permit in accordance with Section 8.124.180.
Table 8.124-1: Allowable Adjustments
B.
Application. An application for an administrative adjustment shall be made to the planning department pursuant to the procedures set forth in Chapter 8.12.
C.
Findings and Decision. The planning director shall, after notice and hearing in accordance with the procedures set forth in Government Code Section 65905, approve, approve with conditions or deny an adjustment application. The director may approve an adjustment application, with or without conditions, only after the following findings are made:
(1)
The adjustment would allow for an ADU of superior design, livability or quality than could be constructed without the adjustment.
(2)
The ADU will not adversely affect the privacy, light, air or views of neighboring properties.
(3)
The adjustment will not be detrimental to the public health, safety and welfare.
(4)
The ADU complies with the other applicable standards set forth in Sections 8.124.130 and 8.124.140.
D.
Appeal. The decision of the planning director may be appealed, in accordance with the procedures set forth in Chapter 8.12.
(Ord. No. 296, § 3, 4-14-2021)
A proposed attached or detached ADU that an applicant seeks to establish that does not comply with the development standards set forth in Section 8.124.130 may be allowed subject to a conditional use permit. The applicant shall be required to obtain a building permit prior to the construction of any attached or detached ADU for which a conditional use permit is required, and shall also meet the requirements set forth in Article 5 of this chapter. Design review for such attached or detached ADUs may also be required pursuant to Section 8.124.190. An application for a conditional use permit (CUP) for an ADU subject to this Article 4 shall be processed in accordance with Chapter 8.12 of the Moraga Municipal Code, except as expressly set forth in this Section 8.124.180 and Section 8.124.190. In addition to the required findings set forth in Section 8.12.120, the following supplemental findings shall also be made prior to the issuance of a CUP for an attached or detached ADU:
A.

(Ord. No. 296, § 3, 4-14-2021)
The purpose of this article is to provide procedures and standards for the review and approval of ADUs that do not meet one or more of the development and/or design standards set forth in Sections 8.124.130 and 8.124.140, respectively. The intent of these procedures is to reasonably allow such units to be established, subject to administrative adjustment or discretionary review, even when they would not qualify for ministerial review and approval pursuant to the requirements of state law, thereby increasing the opportunities for ADUs to be developed in the town.
(Ord. No. 296, § 3, 4-14-2021)
This article is only applicable to provide alternative processes to the statutory requirements for ministerial review, and to thereby provide for minor administrative adjustments and a system of discretionary review in a manner designed to increase opportunities for ADUs to be developed in the town beyond that which is required by state law. In no event shall this article be interpreted to expand or otherwise amend the requirements for ministerial review set forth in Article 3.
(Ord. No. 296, § 3, 4-14-2021)
A.
Allowable Adjustments. The planning director may approve a minor adjustment to the development or design standards applicable to an application for an attached or detached standard ADU governed by Article 3, to the extent identified in Table 8.124-1. Only a maximum of two of the allowable adjustments may be granted for such an ADU per parcel. A request for more than two adjustments or that exceeds the adjustment limitations identified in Table 8.124-1 may not be reviewed under Article 3, governing ministerial review, and this Section 8.124.170 and shall require an application for a conditional use permit in accordance with Section 8.124.180.
