Building Setbacks & Zoning in San Rafael, CA: What Residents Actually Need to Know

If you live in San Rafael or are thinking about moving there, building setbacks & zoning are one of those things you probably won't think about until they affect you directly. San Rafael has 3 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.

Structure Height Limits

San Rafael caps single-family homes at 30 feet in every R district, R2a, R1a, R20, R10, R7.5 and R5, under Table 14.04.030, with a lower 17-foot peak allowed only in the -EA Environmental/Architectural combining district.

Key details: Height limit: 30 feet, all R districts. EA overlay limit: 17 feet to peak. Multi-family limit: 30-36 ft, DR/MR/HR districts. Relief mechanism: Chapter 14.24 height exception.

Building above the 30-foot cap without an approved exception under Chapter 14.24 is a zoning violation; the city can withhold approvals, require modification, and enforce as a misdemeanor under the zoning code.

Lot Coverage Limits

San Rafael limits how much of a residential lot can be covered by buildings, from 20% in the largest-lot R2a district up to 40% in R10, R7.5 and R5, under Table 14.04.030, with ground-level walkways, patios and sheds under 120 sq ft excluded from the calculation.

Key details: R2a coverage cap: 20% of lot. R10/R7.5/R5 cap: 40% of lot. Excluded: sheds/decks under 120 sq ft. Defined at: SRMC § 14.03.030.

Exceeding the district's maximum lot coverage without an approved variance or exception under Chapters 14.23 or 14.24 is a zoning violation, subject to permit denial, required modification, and misdemeanor enforcement under the zoning code.

Setback Rules

San Rafael's single-family residential zones set separate front, side and rear yard minimums under Table 14.04.030: front yards run 15 to 20 feet, side yards from 6 feet up to 15% of lot width, and rear yards 10 to 25 feet depending on the R2a through R5 zone, all capped at 30 feet in building height.

Key details: Front setback: 20 ft in R2a/R1a/R20/R10; 15 ft in R7.5/R5. Side/street side setback: 6-15 ft, or 10% of lot width in R5. Rear setback: 25 ft in R2a/R1a; 10 ft in R20-R5. Max structure height: 30 feet in every single-family zone. Max lot coverage: 20% to 40% depending on zone.

Section 14.30.040 makes it unlawful to build without complying with the terms of any permit or approval issued under Title 14, and Section 14.30.050 treats each day a structure remains out of compliance as a separate violation. Under Section 14.30.060 the code enforcement officer or planning director may revoke the permit, issue a citation with fees under Section 1.42.010, or pursue nuisance abatement under Chapters 1.16 and 1.20; the city attorney may also prosecute a Title 14 violation as a misdemeanor under Section 1.42.010.

The Bottom Line

San Rafael's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming San Rafael is broadly strict or permissive.
