Covina incorporated in 1901 as 'One Mile Square and All There,' grew into one of the world's leading orange producers, then traded its groves for postwar neighborhoods. Its parcels span a century of records, from the original townsite to the tract era.
Townsite lot, grove-era tract, or downtown building — name the parcel and we will shape the scope. Call (213) 787-3342 to talk it through.
The original townsite — the famous square mile — still anchors downtown Covina, with its early-1900s commercial blocks and the city's oldest residential streets around them. By 1909 the groves surrounding that core made Covina the third-largest orange producer in the world, and when the postwar boom arrived, those groves converted to housing tract by tract.
The result is a city in rings, and survey questions follow the rings. Townsite and early lots carry the oldest records and scarcest monuments. Grove-conversion tracts carry mid-century geometry with the usual worn evidence. Everywhere, the practical questions are the same: where the lines are, what the setbacks measure, and what the record says when fences disagree.
Retracing the townsite core is research work: century-old plats, generations of deeds, and evidence that survives in fragments beneath rebuilt streets. Grove-conversion tracts are friendlier — their maps are younger and internally consistent — but the conversions happened orchard by orchard, so adjacent tracts sometimes meet at seams where geometry deserves careful reconciliation.
Downtown adds a commercial layer: older buildings close to or on their lines, shared walls, and remodels that need measured documentation. Residentially, Covina generates steady setback and ADU work on lots where garages and additions have accumulated for seventy years. Whatever the ring, the survey's job is constant — convert the record into reliable lines on the ground.
Six services cover most Covina requests — lines and corners first, documentation where projects need it:
The projects that bring Covina owners in usually involve:
Any of these focus the research and firm the number:
We identify the parcel's ring — townsite, grove tract, or later — assemble its record, confirm scope, then field-measure and deliver. Steps on our how it works page.
The townsite's records are the city's oldest, so retracement there leans harder on research — early plats, long deed chains, and block-wide evidence searches. Outside the square, grove-conversion tracts carry younger, cleaner records. Same method everywhere; the square just asks for more history.
Mostly clean tract geometry — and occasional seams. Groves converted one at a time, so neighboring subdivisions can meet at slight angles or leave slivers where the orchard boundaries ran. Most lots retrace without drama; when something odd appears at a tract edge, the grove-era parcel fabric usually explains it.
A survey that shows exactly how the building, its walls, and its neighbors sit relative to the lines — typically an ALTA/NSPS survey for financed purchases, or a detailed boundary survey otherwise. Old commercial blocks grew up interdependent, and the measured picture is what title and lenders want before close.
It can be either a sketch or a measured drawing, and reviewers increasingly want the latter when the fence runs near a line. A survey-based plot plan shows the located boundary and the proposed fence with real dimensions — which is precisely what removes the reviewer's doubt and keeps the permit moving.
That is a measurement, not a mystery: we locate the line and the current wall and report the distance to the inch. Accumulated projects often consume more margin than owners realize, and knowing the true remaining setback is the first fact any future addition — or sale — will need.
