Condo Conversions in San Leandro, CA

San Leandro’s conversion candidates fall into two groups: the small apartment buildings and duplexes scattered through its flat postwar tracts, and the more ambitious industrial-to-residential projects the city has encouraged as older commercial and industrial buildings find new life. Both follow the same legal template — a subdivision map under the Subdivision Map Act (parcel map for four or fewer units, tract map for five or more) plus a condominium plan under the Davis-Stirling Common Interest Development Act defining unit boundaries, common area, and exclusive-use areas. Maps are reviewed by the Alameda County Surveyor’s office, and map and condominium plan record with the Alameda County Recorder. And as in every East Bay city, San Leandro’s own local rules on converting existing units are the practical gatekeeper — confirming the current ordinance with the city is step one, before survey dollars are spent.

San Leandro adds a boundary consideration few cities can match: the Hayward fault runs directly through town, creeping aseismically at a measurable rate — famously visible in offset curbs and sidewalks. For a conversion property near the fault trace, the boundary survey under the map deserves particular care, because monuments and improvements on opposite sides of the trace are slowly moving relative to each other. We retrace the record boundary, evaluate what the monuments are actually telling us, and preserve controlling monuments as Business and Professions Code §8771 requires before the map records. West of I-880, mapped liquefaction zones raise the separate issue of long-term building settlement.

That settlement is exactly why we scan. Whether the building is a 1950s fourplex or a former industrial structure being carved into residential units, our Trimble terrestrial laser scanner captures every unit, common space, and the exterior in a single visit as a survey-grade point cloud. Industrial conversions especially benefit: irregular column grids, sloped warehouse slabs, and mezzanines make hand measurement unreliable, while the point cloud lets us draft three-dimensional unit boundaries that match the structure as built. The same dataset serves the architect’s design work — see 3D laser scanning.
