The hatched band is the yard — ground the code gives up. Drawn not to scale: the yards are proportional to each other, so the deepest one fills the band and the rest follow. The dimensions carry the real numbers, and the export draws them on the actual parcel outline.

Larkspur setbacks by district

Every row is produced by the same function the exporter calls, so this page cannot drift from what the drawing gets. The citation under each row is what prints on the sheet.

Larkspur setback FAQ

What are the residential setbacks in Larkspur?

In R-1 the code sets a 20 ft front yard, 6 ft sides, and a 15 ft rear yard. The full table is below, transcribed from Larkspur Municipal Code §18.20.060, R-1 with the citation attached to every row. This table has passed independent review, so Lekua draws the setback envelope on the site plan for a Larkspur parcel.

Does Lekua draw the setback envelope for Larkspur?

Yes. Larkspur is one of the jurisdictions whose table has passed review, most recently on 2026-07-23, so the envelope is drawn on the DXF and the PDF site plan with its citation in the title block.

Where do these Larkspur setback numbers come from?

They are transcribed from the adopted code — Larkspur Municipal Code §18.20.060, R-1 — and this page renders them by calling the same function the exporter calls, so what you see here is what the drawing gets. Zoning changes; verify against the current code and with the planning department before submittal.

Can I get a CAD base map for a Larkspur parcel?

Yes. Enter any Larkspur address and Lekua returns a layered DXF base plan and a PDF site report — property lines, 1–2 ft contours, building footprints, CAL FIRE defensible-space zones, soil, seasonal sun, and a native plant palette matched to the parcel, alongside the zoning determination.
