Ross 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 Ross address and the setbacks arrive already drawn.
The envelope
What the numbers below make on the ground. Shown for the first district in the table; the rest follow the same geometry at their own dimensions.

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.
Ross 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.
Ross Municipal Code §18.16.050, R-1 (incl. :B-6/7.5/10/15/20/A): front 25, side 15, rear 40. Detached rear garages: >=10 ft from side/rear lines; design review applies broadly in Ross. Verify with Town of Ross Planning.
What the export says about this table
Ross reviewed against RMC §18.16.050 (captured 2026-06-12): side yard 15 ft in all R-1 districts; general R-1 25/15/40. The :B-5A and :B-10A districts carry a 70 ft rear yard — confirm the district suffix with the Town before relying on a rear yard. Design review applies broadly.
Printed verbatim on every Ross export — the same words the reviewer signed off, not a summary of them.
Setbacks are one layer of the Ross 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→
Ross setback FAQ
What are the residential setbacks in Ross?
In R-1 the code sets a 25 ft front yard, 15 ft sides, and a 40 ft rear yard. The full table is below, transcribed from Ross Municipal Code §18.16.050, 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 Ross parcel.
Does Lekua draw the setback envelope for Ross?
Yes. Ross 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 Ross setback numbers come from?
They are transcribed from the adopted code — Ross Municipal Code §18.16.050, 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 Ross parcel?
Yes. Enter any Ross 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.
