Retaining wall permits usually need existing grades plus property-line and setback information — especially on slopes. We provide the survey your LA building department and engineer need.
Tell us what the city, county, architect, or engineer requested — we’ll help determine whether you need boundary, topo, setback, hillside, or permit survey support. Call now to discuss your project.
A retaining wall holds back earth, so the building department and your structural engineer need to know the existing grades and where the wall sits relative to the property lines. That usually means a topographic survey plus property-line/setback information — and on a slope, more detail still.
Walls close to a boundary draw extra scrutiny — and disputes. We verify the true line so the wall is placed correctly and your setbacks are documented before you build. See setback verification.
Hillside walls combine steep grades and stricter review. We capture denser terrain data and can pair the survey with hillside and grading-plan work so your engineer has what they need.
Usually yes — the building department and your structural engineer need existing grades and, when the wall is near a boundary, property-line/setback information.
Often both: a topo for grades and drainage, plus property-line/setback work if the wall is near a line. We’ll scope it for your wall and lot.

Timing depends on site size, terrain, access, and records research; we confirm the expected schedule with your quote.
No. It provides the survey your permit and engineer need; the city makes the final decision.
A survey supports plan check, design, and code review. It does not guarantee permit approval — the city or county building and planning departments make the final decision. Our job is to make your project survey-ready.
Survey scope and deliverables depend on title records, site conditions, and what your project requires. Call (213) 787-3342 to discuss the property and the survey you need.
