Los Angeles County · Land Surveying
Norwalk's neighborhoods rose in a single postwar generation on former dairy and beet fields, and today the city is one of the county's steadiest sources of small-lot survey questions: fences, driveways, garage conversions, and room additions on compact tract parcels.
Fence, ADU, or escrow question — describe it in a sentence and we will tell you which survey answers it. Call (213) 787-3342 to talk it through.
Before the subdivisions, this was farm country — development began with the Sproul brothers in 1869, and dairies and sugar beets dominated the landscape into the postwar years. The tracts that replaced them filled quickly with modest single-family homes on rectangular lots, the housing stock that still defines Norwalk today.
Compact lots keep survey questions practical: where exactly the side line runs before a fence is replaced, whether a garage sits far enough from the rear line to become an ADU, how much yard a driveway widening can legally take. Owners also call ahead of sales and refinances when something on the ground looks different from the paperwork.
Postwar tracts here were recorded rapidly but to consistent standards, so the record geometry is usually sound. The field evidence is the variable: decades of curb replacements, sewer work, and fence cycles have buried or destroyed many original monuments. We retrace from what survives across the block and re-establish missing corners against the recorded map, filing county corner records where corners must be reset.
The city's freeway frame — I-5 through the middle, I-605 on the west side, the 91 at the south — put Norwalk within commuting reach of the whole region, which keeps its housing turning over and its parcels changing hands. Transactions are where boundary surprises surface, and a survey before close is far easier than a dispute after.
Five services answer most Norwalk questions — the first two differ in whether the line is trusted or contested:
The calls we get from Norwalk owners typically involve:

We start from the recorded tract map and nearby surveys, confirm what deliverable your project needs, then set fieldwork. The step-by-step is on the how it works page.
One early fence gets built off the line and every neighbor matches it — a pattern we see across postwar tracts. The recorded map controls, not the fences; a retracement shows each parcel where its true lines are, and neighbors can then decide together what to do about the drift.
Requirements come from the city's plan review, not from us, but conversions near a property line commonly need measured setbacks taken from located lines rather than estimates. That is a compact scope on a typical Norwalk lot, and it addresses the question reviewers most often raise.
Fences off the line, a neighbor's planter or driveway over it, or a simple accumulation of small encroachments. The record width is geometric; the survey shows where that geometry lands on the ground and what currently occupies it — from there the difference has an explanation.
That is a decision for you, your neighbor, and possibly your title company — our role is the measured fact of where the shed sits relative to the line. Many owners simply document the situation; others negotiate or relocate. All of those options start with the survey.
When corners are re-established, California practice calls for documenting the work, typically through a corner record filed with Los Angeles County. It creates a public record of the monuments so future surveys and owners inherit the evidence rather than the mystery.
