The research surveyors and architects run before they draw a line — now for your own property in Los Angeles County. Enter an address or parcel number and see what's on record, free. When you're ready, one dollar takes the whole package home: the map, the report, and a tentative CAD file — accurate, not precise, and not a survey.
Free to look · $1 to take it home · no card needed to run
↑ A real project screen: the property outlined in red, every recorded survey and map drawn where it lies, control points at the corners — the same screen a surveyor works from.
First, the thing nobody tells you
Most owners believe they have a survey. What they have is the assessor's parcel map — and it says on its face that it is not a survey. AEC First Phase shows you what is actually on record for your lot: the recorded surveys and maps around it, the corner records, the benchmarks, the zoning, the terrain — placed on one map, with the distance from your property to each one.
How it works
Or the 10-digit parcel number. It is verified against the county parcel record and its jurisdiction identified, so the right records are searched automatically.
Recorded surveys, parcel and tract maps, corner records, benchmarks, zoning and terrain around your site — about ten minutes, while you watch the checklist.
Everything found, drawn at its true location. Pick what you want. One dollar unlocks the property and the package downloads as one zip — and stays yours to come back to.
The deliverable
Compiled from public records, as found. Not a survey; sets no boundary. Verify before you rely on it — and hand it to your professional when it's time.
See an example
A simplified cut of one real project: the lot and its neighbours, the streets, the aerial and the 1-ft contours. This is only a portion of what you actually get — the full package adds the property report, the records you pick, slopes, utilities and easements where the city publishes them, and every reference link in the CAD file.
Who it's for
Survey-level record research: the recorded surveys, parcel and tract maps, corner records, benchmarks and control around the site, placed and listed, with the compiled CAD base on State Plane.
How you'll use it: run the address the day the job comes in, unlock the package, start the boundary analysis from the DXF and the record set.
A tentative base to start concepts: parcel geometry, zoning, terrain and existing conditions from the public record.
How you'll use it: open the DXF as the first base; replace it with a survey before design development.
Site context before the estimate: the parcel map, the terrain, and easements and utilities where the city publishes them.
How you'll use it: bid with fewer unknowns; keep the report in the job file.
Zoning and constraints on day one — the zoning card, the parcel lines and the terrain in one package.
How you'll use it: bring it to the feasibility conversation before anyone draws.
Screen a property in minutes, before a site visit, for a dollar.
How you'll use it: run every candidate address; unlock the ones worth a second look.
Your project's first phase: everything the professionals pull, for your own lot — the records, the report, and a tentative CAD file you can open, measure and hand off.
How you'll use it: open the CAD file in a free viewer (Autodesk Viewer online, DWG TrueView, or LibreCAD) and measure and annotate; drop the report into an AI assistant and ask what the zoning allows; hand the package to your architect, contractor or surveyor.
