Building Setbacks & Zoning in Santa Monica, CA

Santa Monica maintains 115 local ordinances across all categories, and 3 of those deal specifically with building setbacks & zoning. Here is a breakdown of what the city actually requires, what is prohibited, and where Santa Monica falls on the strict-to-permissive spectrum compared to other cities.

Lot Coverage Limits

R1 zone floor area ratio (FAR) ranges from 0.45 to 0.55 depending on the number of stories and whether the project involves an addition to an existing structure rather than new construction.

Key details: One-story < 18 ft. (R1): 0.5 FAR (or 2,500 sq. ft. on small lots). One-story ≥ 18 ft. or two-story (R1): 0.45 FAR (or 2,250 sq. ft.). Addition to existing structure (R1): 0.55 FAR (or 2,750 sq. ft.). Second-story cap on small lots: Max 1,125 sq. ft. on 2nd story for two-story; 1,375 sq. ft. for additions. Small parcel threshold: Under 5,000 sq. ft. uses absolute sq. ft. cap instead of FAR ratio.

Exceeding FAR limits is a zoning violation; building permits are denied for non-compliant designs and code enforcement may require removal of excess floor area.

Setback Rules

In the Bergamot Districts, buildings must be set back from the street curb face by 10 to 20 feet depending on the specific street, and in Mixed-Use/Commercial Districts, buildings adjacent to residential zones must respect a daylight plane starting at 30 feet above the shared property line.

Key details: Nebraska Ave / Pennsylvania Ave setback (Bergamot): 20 feet from curb. Colorado Ave / Olympic Blvd setback (Bergamot): 15 feet from curb. All other streets setback (Bergamot): 10 feet from curb. Daylight plane start height (adjacent to residential): 30 feet above property line. Daylight plane angle: 45 degrees from vertical toward interior.

Projects not meeting building frontage line setbacks or daylight plane requirements would not receive development approval. Encroachments into required setbacks may require a modification or waiver under Chapter 9.43, Modifications and Waivers, which requires specific findings.

Structure Height Limits

In Mixed-Use and Commercial Districts, base (Tier 1) building height is 2 stories/32 feet in most zones, with higher limits available for projects providing affordable housing or community benefits under a tiered system.

Key details: Tier 1 Base Height (most zones): 2 stories / 32 ft. Tier 1 Base Height (NC Ocean Park Blvd & Montana Ave): 2 stories / 27 ft. Tier 1 with On-Site Affordable Housing (MUBL, GC): 3 stories / 36 ft. Tier 2 with Community Benefits (MUB): 3 stories / 45 ft. Tier 2 with Community Benefits + 100% Residential Above Ground (MUB): No story limit / 50 ft maximum.

Construction exceeding permitted heights without required approvals is subject to code enforcement, stop-work orders, and may require removal of non-conforming elements.

The Bottom Line

Santa Monica'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 Santa Monica is broadly strict or permissive.

These rules come from Santa Monica's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
