Carlsbad setback requirements
Lekua resolves a parcel’s jurisdiction and zone, then draws this envelope on the base plan, offset from the county’s parcel line, with its citation. Yards are measured from the surveyed line, so confirm against a survey before siting anything near them.
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.
Carlsbad 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.

What the export says about this table
Carlsbad reviewed 2026-09-25 against Municipal Code Title 21, checked on R-1, R-2 and R-3 lots; the R-A, R-E, R-W and RD-M standards are drawn from the same chapters but were not checked on a sample lot. In R-A, R-1, R-2 and R-3, each side yard is 10% of lot width (5 to 10 ft), and one side may be narrowed to 5 ft if the other is widened by as much; a dwelling must stand twice the side yard from the rear line, and small detached non-habitable structures may sit 5 ft from side, rear and alley lines. The 20 ft front drawn may be 15 ft on key lots and lots beside commercial or industrial property, and 15 or 10 ft in RD-M under stated garage and landscaping conditions. Much of Carlsbad lies inside a master or specific plan whose standards can replace the zone's; the yards drawn are the zone's. Where mapped, coastal overlays add a coastal permit, a stringline ocean setback, a 100 ft lagoon and wetland buffer, and steep-slope and brush-management limits, and the Beach Area Overlay limits height to 30 ft. Master-plan standards, flag lots, other overlays and commercial zones are not yet reviewed.

Setbacks are one layer of a Carlsbad base 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 San Diego County →
Carlsbad setback FAQ
What are the residential setbacks in Carlsbad?
In R-A the code sets a 20 ft front yard, 5 ft sides, and a 10 ft rear yard. The full table is below, transcribed from Carlsbad MC Ch. 21.08 with the citation attached to every row. This table has passed independent review, so Lekua draws the setback envelope on the base plan for a Carlsbad parcel.
Does Lekua draw the setback envelope for Carlsbad?
Yes. Carlsbad is one of the jurisdictions whose table has passed review, most recently on 2026-09-25, so the envelope is drawn on the DXF and PDF base plan, with its citation.
Where do these Carlsbad setback numbers come from?
They are transcribed from the adopted code — Carlsbad MC Ch. 21.08 — 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 Carlsbad parcel?
Yes. Enter any Carlsbad address and Lekua returns a layered DXF base plan and a PDF site report — county parcel lines, fine contours (1–2 ft on demand, or the county’s own where it publishes them), building footprints, CAL FIRE defensible-space zones, soil, seasonal sun, and a native plant palette matched to the parcel, alongside zoning.
