San Rafael Zoning Intelligence

San Rafael has an explicit tiered multifamily zoning structure. HR1, HR1.5, and HR1.8 High Density Multi Family districts (covering 69, 74.83, and 50.35 acres respectively) permit the densest residential uses, while MR2, MR2.5, MR3, and MR5 Medium Density Multi Family districts provide a range of intermediate densities. Collectively, these districts make San Rafael one of the better-zoned multifamily markets in Marin County, which has historically constrained housing supply. Density bonus applications on qualifying sites in HR and MR zones can unlock additional units above base zoning.

The /C overlay applies to properties along the San Rafael Canal, one of the Bay Area's most distinctive waterfront corridors and a historically underserved neighborhood undergoing reinvestment. Projects in /C-designated zones face design review focused on canal access, view corridors, building orientation, and compatibility with the waterfront character. Districts like DR-C (Duplex Residential Canalfront), HR1-C, and M-C (Marine Canalfront) combine their base use standards with this additional review layer. Developers evaluating canal-adjacent sites should engage early with the planning department on design standards.

Light Industrial Office (LI/O) at 188.40 acres and Core Canal Industrial Office (CCI/O) at 36.63 acres are the primary employment districts, accommodating light manufacturing, research and development, professional offices, biotech, and warehousing in appropriate configurations. The /O suffix indicates that office uses are integrated with industrial, making these districts well-suited for Marin County's technology and life-science tenants that need flexible lab-office-light manufacturing space. Industrial (I) at 54.04 acres provides a more intensive industrial tier.

The Marine (M) district at 14.96 acres and the M-C Marine Canalfront variant at 22.75 acres govern water-adjacent and water-dependent uses along the San Rafael waterfront, including boat storage, marine services, waterfront restaurants, and compatible commercial uses. Residential uses are typically restricted in pure M zones but may be permitted in mixed-use marine contexts with discretionary approval. The Wetland Overlay (/WO) variant adds coastal and wetland environmental review for any parcel with a /WO designation. Marina or waterfront hospitality investors should engage early with both the city and the Bay Conservation and Development Commission (BCDC).

The FBWC district at 36.63 acres governs the Francisco Boulevard West corridor - a commercial strip with auto-oriented and service retail uses that the city has been seeking to reimagine as a more pedestrian-friendly mixed-use area. It differs from the broader General Commercial (GC) district in that it applies specific design and use standards tailored to the corridor's redevelopment context. Developers interested in mixed-use infill along this corridor should review the FBWC standards alongside any adopted specific plan or corridor plan for Francisco Boulevard West.
