What should developers know about Larkspur zoning?
Larkspur is a small, established Marin County community, and its 17 zoning districts reflect a town that is overwhelmingly residential and protective of its open hillsides. First Residential (R-1) is by far the largest district at roughly 935 acres, and when combined with Open Space (OS) at about 330 acres and the Planned Development (PD) designation at 255 acres, the picture is clear: this is a built-out, low-density place where single-family neighborhoods and preserved land dominate the map.
Higher-intensity housing exists but is geographically limited. Third Residential (R-3), the principal multifamily district, covers about 187 acres, while Second Residential (R-2) and the Residential Master Plan (RMP) districts handle more specialized housing patterns. Larkspur's small downtown is finely zoned into three distinct character areas - Storefront Downtown (SD), Transitional Downtown (TD), and Garden Downtown (GD) - a level of granularity that signals strong design control and a preference for context-sensitive infill over large-format development. Commercial land is modest, split among Administrative and Professional (AP), Restricted Commercial (C-1), and Commercial (C-2), with a small Light Industrial (LI) pocket of roughly 33 acres.
For developers and investors, the operative reality is that opportunity here is incremental: redevelopment, adaptive reuse, and infill within the downtown character zones or the multifamily R-3 areas, rather than greenfield expansion into protected open space. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.

Larkspur zoning: frequently asked questions
What kind of housing can realistically be developed in Larkspur?
The town is dominated by First Residential (R-1) single-family land at about 935 acres, so detached-home neighborhoods set the baseline character. Meaningful multifamily capacity is concentrated in Third Residential (R-3), roughly 187 acres, with smaller contributions from R-2 and the Residential Master Plan district. Most new units come from infill and redevelopment rather than new subdivisions.
How is downtown Larkspur zoned?
Downtown is split into three character-specific districts: Storefront Downtown (SD), Transitional Downtown (TD), and Garden Downtown (GD). This fine-grained approach means design and use standards shift block by block, so a mixed-use or commercial project's feasibility depends heavily on which of the three a parcel sits in.
Does Larkspur have much commercial or industrial land?
Very little. Commercial is divided among Administrative and Professional (AP), Restricted Commercial (C-1), and Commercial (C-2), each under 30 acres, plus a Light Industrial (LI) area of about 33 acres. Larkspur is not a destination for large retail or industrial development; the inventory simply is not there.
How do the Open Space and Planned Development designations affect a site?
Open Space (OS) covers roughly 330 acres of protected and hillside land where development is sharply constrained, and Planned Development (PD) at about 255 acres ties entitlements to project-specific approvals rather than by-right standards. Buyers should confirm whether a hillside parcel carries OS or PD designation, as either can materially limit buildable area.
Can California housing laws like SB-9 or ADUs help unlock value here?
State ADU law applies to single-family lots throughout Larkspur, and SB-9 lot splits and duplexes can be available on eligible single-family parcels, though hillside, flood, and other site constraints common in Marin can limit application. Because the town has so much R-1 land, these state tools are often the most direct path to added units - verify eligibility and any objective design standards with the city.
