Los Angeles County · Land Surveying
Commerce incorporated in 1960 to keep its industrial land from being annexed away, and industry still covers most of the city — rail-corridor plants, warehouses, and the Citadel's landmark reuse of a former tire factory — alongside residential neighborhoods that make it more than a work zone.
Industrial scopes start from documents — send the title report and the address and we will take it from there. Call (213) 787-3342 to talk it through.
Industry built Commerce: the Santa Fe main line arrived in 1887, the plants followed, and by mid-century the district incorporated as 'The Model City' to protect its tax base from neighboring cities. Industrial uses cover well over half the land — big parcels, rail spurs, truck yards, and generations of manufacturing history in the records.
But unlike its neighbor Vernon, Commerce houses a real residential community — roughly twelve thousand residents in neighborhoods threaded between the industrial districts. That gives the city two survey dockets at once: transaction and construction work on the industrial side, and the familiar line, setback, and ADU questions on the residential blocks.
Industrial retracement here reads a century of records: early acreage subdivisions, railroad conveyances along the corridors, street vacations, and parcels assembled and reassembled as plants grew. ALTA/NSPS surveys for acquisitions and refinances plot that history against the physical site; as-built and topographic mapping support the retrofits and yard rebuilds that keep old plants competitive.
Adaptive reuse adds a modern layer — the Citadel's conversion of a landmark tire factory is the famous example, and smaller conversions happen continually. Reuse projects inherit industrial-era title: old easements, rail rights, and utility corridors that must be located before redevelopment commits. On the residential side, the work is classic small-lot surveying, done with the same record discipline.
Six services cover both fabrics — three transactional and construction-side, three for lines and documentation:
Typical Commerce situations that reach a surveyor:
Industrial scopes run on paper; residential ones on basics:
We build the record chain, confirm scope in writing, then schedule fieldwork around operations. The broader sequence is on our how it works page.
The industrial dockets look alike — rail-era records, assembled parcels, ALTA-driven transactions. The difference is Commerce's residential neighborhoods, which add everyday line and setback work Vernon barely has. We treat them as two dockets with one standard of record research.
The railroad's conveyance history — a chain of instruments as old as the 1887 main line — plus your own parcel's chain. Corridor boundaries are retraced from both, and the result shows exactly where your yard ends against the right-of-way. Fieldwork near active track gets planned conservatively.
Reuse inherits title. Converted parcels carry their industrial past as recorded easements, rail rights, and utility corridors that survive the change of use, and redevelopment lenders want them plotted, not assumed. An ALTA/NSPS survey does exactly that — the paper history mapped onto the modern site.
The method is standard small-lot surveying; the context adds value. Where homes border industrial parcels, a clearly monumented line prevents the gradual drift of pavement, storage, and fencing across it. We mark residential lines durably and document restored corners with the county.
Yes — lease and operations agreements often call for the occupied edge to be verified against the recorded boundary. We locate the fence and the line, report the relationship, and provide the exhibit the lease file needs. When the fence is off the line, the measured map is what gets it corrected or papered.
