Title 18 — ZONING

Chapter 18.31 — ACCESSORY DWELLING UNITS/JUNIOR ACCESSORY DWELLING UNITS

Corte Madera Municipal Code · 2026-09 edition · updated 2026-10-02 · Corte Madera

Editor's note— Ord. No. 1043, § 5, adopted December 17, 2024, repealed the former Ch. 18.31, §§ 18.31.010—18.31.130, and enacted a new Ch. 18.31 as set out herein. The former Ch. 18.31 pertained to similar subject matter and derived from Ord. 961 § 8, adopted Dec. 6, 2016; Ord. No. 962, § 7, adopted Dec. 6, 2016; Ord. No. 992, § 8, adopted Jan. 21, 2020; and Ord. No. 993, § 6, adopted May 19, 2020.

18.31.010 - Purpose.

The purpose of this chapter is to establish the procedures and development standards for the ministerial, non-discretionary processing of applications for new accessory dwelling units ("ADUs") and junior accessory dwelling units ("JADUs") in compliance with California Government Code Sections 66310 through 66342 and consistent with the policies, goals and programs of the Housing Element of the General Plan. ADUs and JADUs increase the overall supply of housing within established residential neighborhoods or as part of new residential subdivisions. Such units are intended to increase the supply of smaller, more affordable housing within existing residential neighborhoods and provide independent living units for prospective and current residents, including family members, students, local employees, the elderly, in- home health and childcare providers, and single adults, among others.

The intent of the Town in adopting the code section is to ensure that the Town's ordinance has the effect of providing for the creation of ADUs and JADUs and that the provisions in this chapter relating to matters including size, parking, and other development standards are not arbitrary, excessive, or burdensome so as to unreasonably restrict the ability of homeowners to create ADUs or JADUs consistent with state law intended to promote their development.

Approval of an Urban Lot Split application is a ministerial act, and therefore is not subject to the California Environmental Quality Act.

At least 10 days prior to rendering a decision, the Planning Division shall mail a courtesy notice to all owners of property within 300 feet of the site of the Urban Lot Split. The notice shall have a brief description of the project and state that this is a ministerial application that is not subject to Design Review, public hearing, or discretionary review.

If staff determines that the application is incomplete, the notification shall include a detailed description of the information needed to complete it.

(c)

Compliance Review:

The Zoning Administrator's review shall be limited to consistency with Government Code Section 65852.21 and the then-current objective standards applicable under this chapter.

(d)

Decision on the Project.

The Zoning Administrator shall approve the project if it complies with Section 68582.21 and the then- applicable objective standards in this chapter.

Approval of a Two-Unit Development application is a ministerial act, and therefore is not subject to the California Environmental Quality Act.

The Zoning Administrator may grant an exception to the requirements of this section for a Two-Unit Development, but only to the extent required by Government Code Section 66852.21(b) to avoid physically precluding either of the two units from being 800 square feet.

The Zoning Administrator may impose such conditions of approval that are objective, broadly applicable to housing in the Town and consistent with Section 68582.21.

If the Zoning Administrator finds that the project is non-compliant, staff will provide the applicant with notice of the standards not met by the project and an explanation of the conflict with each such standard. The applicant may re-submit the application with corrections to achieve compliance. The Zoning Administrator shall review the resubmitted application and render a finding regarding compliance within 30 days.

In addition to the criteria listed in Section 18.31A.050, a proposed Two-Unit Development may be denied if the Building Official makes a written finding, based on a preponderance of the evidence, that the proposed housing development project would have a specific, adverse impact upon public health and safety, as defined and determined in Section 65589.5(d)(2) for which there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact.

If the project is ineligible for processing and approval under Section 65852.21 and this chapter, the applicant may submit the project under other applicable chapters of this title.

Any modifications proposed following the approval of the project shall be submitted to the Planning Division for review and approval. The Zoning Administrator shall review the post approval project modifications to ensure the modifications comply with Section 68582.21 and the applicable objective standards in Section 18.31A.050(b) and Title 22.

The fee for a review request shall be the fee established in the adopted fee schedule in effect at the time of submittal.

(e)

Subsequent Review of the Record. The decision of the Zoning Administrator granting or denying a Two- Unit Development is a ministerial decision as required by state law and shall not be subject to a public hearing. Following the decision of the Zoning Administrator, an interested party may request in writing a review of the record with the Town Clerk within ten calendar days of the date of the decision. Within ten calendar days after receipt of the request for review of the record, the Town Manager, or his/her designee, shall conduct a review of the record based on all documents submitted as part of the application and review process. In calculating the ten days for review of the record, the request for review will be deemed to be received on the first day that Town Hall is open to the public after receipt of the request. The fee to request a review shall be the fee established in the adopted fee schedule in effect at the time of submittal. The Two-Unit Development applicant and individual(s) filing for the review shall be notified in writing of the decision and such decision shall be final.

(f)

A limitation restricting the property to residential uses only; and

B.

A requirement that any dwelling units on the property may be rented or leased only for a period of longer than thirty (30) days.

The Town Manager or that person's designee is authorized to enter into the covenant and agreement on behalf of the Town and to deliver any approvals or consents required by the covenant.

(g)

In addition to the criteria listed in this section, a proposed Two-Unit Development may be denied if the Building Official makes a written finding, based on a preponderance of the evidence, that the proposed housing development project would have a specific, adverse impact upon public health and safety as defined and determined in Section 65589.5(d)(2) for which there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact.
