Mill Valley 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 Mill Valley address and the setbacks arrive already drawn.
The envelope

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.
Mill Valley 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.
Mill Valley MVMC §20.16.040(C): exterior (street-facing) yards 15 ft; interior yards 1 ft per 1,000 sq ft of effective lot area, min 5 / max 15 — interior 5–15 ft by formula (lot area unavailable — rings drawn at the 15 ft maximum). §20.60.070 exceptions apply; RS-3A/5A/10A require a Planning Commission site development plan (§20.16.025). Verify with Mill Valley Planning.
What the export says about this table
Mill Valley reviewed against MVMC §20.16.040(C) (captured 2026-06-11): exterior (street-facing) yards 15 ft; interior yards 1 ft per 1,000 sf of effective lot area, limited to 5-15 ft. RS-3A/5A/10A site-plan districts and the effective-versus-gross lot area rule (§20.08.090) are not captured. Confirm the parcel is inside city limits — Mill Valley mailing addresses extend into unincorporated Marin, which has its own standards.
Printed verbatim on every Mill Valley export — the same words the reviewer signed off, not a summary of them.
Setbacks are one layer of the Mill Valley 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→
Mill Valley setback FAQ
What are the residential setbacks in Mill Valley?
In RS the code sets a 15 ft front yard, 15 ft sides, and a 15 ft rear yard. The full table is below, transcribed from Mill Valley MVMC §20.16.040 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 Mill Valley parcel.
Does Lekua draw the setback envelope for Mill Valley?
Yes. Mill Valley 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 Mill Valley setback numbers come from?
They are transcribed from the adopted code — Mill Valley MVMC §20.16.040 — 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 Mill Valley parcel?
Yes. Enter any Mill Valley 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.
