San Anselmo setback requirements
Lekua resolves a parcel’s jurisdiction and zone, then draws this envelope on the site plan with its citation in the title block. Enter a San Anselmo address and the setbacks arrive already drawn.
The envelope
What the numbers below make on the ground. San Anselmo sets one bracket across every R district, so this is the whole rule rather than one district of several.
Zone R-1 — the envelope Lekua draws on the plan.
- Front
- 20′
- Side
- 8′
- Rear
- 20′
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.
San Anselmo 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.
Corner lots: 12′ on the secondary street frontage.
San Anselmo Development Standards Table 4A: front 20, interior side 8 (street side 12), rear 20. Table 4B residential-project exceptions (note 2) and ridgezone rules may modify. Verify with San Anselmo Planning.
What the export says about this table
San Anselmo R-1 reviewed 2026-07-20 against Development Standards Table 4A: front 20, interior side 8, street side 12, rear 20. Ridgezone overlay and creek-adjacent standards are not captured — confirm overlays with Town Planning.
Printed verbatim on every San Anselmo export — the same words the reviewer signed off, not a summary of them.
Setbacks are one layer of the San Anselmo site plan
The same address search returns the parcel boundary, 1–2 ft contours, building footprints, CAL FIRE defensible-space zones, the soil profile, four-season sun, and a native plant palette matched to the site. See everything Lekua resolves in Marin County→
San Anselmo setback FAQ
What are the residential setbacks in San Anselmo?
In R-1 the code sets a 20 ft front yard, 8 ft sides, and a 20 ft rear yard. The full table is below, transcribed from San Anselmo Development Standards Table 4A 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 San Anselmo parcel.
Does Lekua draw the setback envelope for San Anselmo?
Yes. San Anselmo is one of the jurisdictions whose table has passed review, most recently on 2026-07-20, so the envelope is drawn on the DXF and the PDF site plan with its citation in the title block.
Where do these San Anselmo setback numbers come from?
They are transcribed from the adopted code — San Anselmo Development Standards Table 4A — 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 San Anselmo parcel?
Yes. Enter any San Anselmo 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.
