Title 1 — General Provisions (Abatement)Chapter 22.30 — STANDARDS FOR SPECIFIC COMMUNITIES

§ 22.64

Marin County Planning Code · 2026-07 edition · ingested 2026-07-08 · Marin County

22.64.010 - Purpose of Chapter.

This Chapter establishes procedures for various types of Housing Development Regulation Compliance Reviews (Housing Compliance Reviews) that provide for ministerial review of housing development project applications.

(Ord. No. 3780, § 1(exh. A), 2023)

22.64.020 - Applicability.

There are three distinct types of Housing Compliance Review applications, which apply as described below:

A.

Type 1. Development proposed in the Form Based (FB) combining district, under the regulations of the Marin County Form Based Code.

B.

Type 2. Development proposed under the statutory authority of Senate Bill 9 (2021, as subsequently amended). Urban lot split applications are reviewed under the Urban Lot Split provisions in section 22.80.064.

C.

Type 3. Development proposed under the statutory authority of Senate Bill 35 (2018, as subsequently amended), if applicable.

Application of the Housing Compliance Review preempts the application of discretionary development entitlements. Specific procedures for reviewing these three types of applications are provided in this Chapter. All of these types of review are ministerial in nature and shall conform to the requirements of Development Code Section 22.40.052 for ministerial planning permit reviews, except for those deviations specifically established in this Chapter.

(Ord. No. 3780, § 1(exh. A), 2023; Ord. No. 3819, § I(exh. A), 2024)

22.64.030 - Application Filing.

An application for a Housing Compliance Review shall be submitted, filed, and processed in compliance with and in the manner described in Chapter 22.40 (Application Filing and Processing, Fees).

Housing Compliance Review application forms are available online and at the Agency's public service counter.

(Ord. No. 3780, § 1(exh. A), 2023)

22.64.040 - Application Review for Type 1 Projects (Form Based).

The Director may only approve or conditionally approve an application for a Type 1 Housing Compliance Review if the project is consistent with all of the applicable standards in the Marin County Form Based Code. Deviations from these standards are subject to Design Review (Chapter 22.42), or the Exceptions process for civil engineering standards (Chapter 24.15) related to parking and access improvements.

(Ord. No. 3780, § 1(exh. A), 2023)

22.64.050 - Application Review for Type 2 Projects (SB 9).

The Director may only approve or conditionally approve an application for a Type 2 Housing Compliance Review if the project is consistent with all of the applicable standards in Section 22.32.184 (Senate Bill 9 Development Standards).

The County shall only deny a Type 2 Housing Compliance Review application that is otherwise eligible for SB 9 processing if the building official makes a written finding, based upon a preponderance of the evidence, that the proposed housing development would have a specific, adverse impact, as defined and determined in paragraph (2) of subdivision (d) of California Government Code Section 65589.5, upon public health and safety or the physical environment and for which there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact.

(Ord. No. 3780, § 1(exh. A), 2023)

22.64.060 - Application Review for Type 3 Projects (SB 35).

All sites for Type 3 (SB 35, if applicable) projects are governed by the FB (Form Based) Combining District. The Planning Commission is the Review Authority for Type 3 (SB 35) projects, and the Planning Commission may only approve or conditionally approve an application for a Type 3 Housing Compliance Review if the project is consistent with all of the applicable standards in the Marin County Form Based Code.

D.

Formal Application. If the development remains eligible to apply under Senate Bill 35 after scoping consultation consistent with Government Code Section 65913.4(b) has concluded, an applicant may file a formal Senate Bill 35 application for compliance review.

E.

Compliance Review.

1.

The final review of a formal application shall be done by the Planning Commission during a hearing to determine if the application complies with all of the provisions contained in this Development Code, Government Code Section 65913.4(a), and standards of the Marin County Form Based Code, and shall occur within the following timeframes:

a.

Within 90 calendar days of formal application submittal for applications that include 150 or fewer housing units.

b.

Non-Compliant Application. If the application does not demonstrate compliance with all of the provisions contained in this Development Code, Government Code Section 65913.4(a), and all applicable objective standards, then the Planning Commission shall provide the applicant with written documentation of which standards the development conflicts with and an explanation of the reasons the development conflicts with each standard.

2.

Conditions of Approval. The Planning Commission may impose conditions of approval provided those conditions of approval are objective and broadly applicable to development within the County.

G.

Post-decision Procedures.

1.

Subsequent Permits. Any necessary subsequent permits shall be issued on a ministerial basis subject to applicable objective standards. If a public improvement is necessary to implement a development subject to this Section, and that public improvement is located on land owned by the County, the County shall process any approvals needed as required by Government Code Section 65913.4(h).

2.

Post-Approval Modifications.

a.

Post-Approval Modification Request. An applicant or the County may request a modification to an approved development if that request is made prior to the issuance of the final building permit.

b.

Applicability of Objective Standards to Modifications. The County shall only apply objective standards in effect when the original application was submitted, except that objective standards adopted after the date of original submittal may be applied when: 1) the total number of residential units or total square footage of construction changes by 15 percent or more; or 2) when the total number of residential units or total square footage of construction changes by five percent or more, and it is necessary to subject the development to an objective standard beyond those in effect when the application was submitted in order to mitigate or avoid a specific adverse impact upon public health of safety, for which there is no feasible alternative

method to satisfactorily mitigate or avoid. Objective building standards contained in the California Building Code, as adopted by the County, shall be applied to all modifications.

c.

Post-Approval Modification Review Timeframe and Decision. The County shall determine if the modification is consistent with objective planning standards and issue a decision on the applicant's modification request within 60 days after submittal unless a new Type 3 Housing Development Review application is required, in which case a decision shall be made within 90 days.

3.

Expiration. An application approved consistent with this section shall remain valid for three years; however, an application approval shall not expire if the development includes public investment in housing affordability, beyond tax credits, where 50 percent of the units are affordable to households making at or below 80 percent of the area median income consistent with Government Code Section 65913.4(e).

4.

Extension. At the discretion of the Director, a one-year extension may be granted consistent with Government Code Section 65913.4(e).
